Big and Small Underwater Faces — 3rd Place. Trips to the Antarctic Peninsula always yield amazing encounters with leopard seals (Hydrurga leptonyx). Boldly approaching me and baring his teeth, this individual was keen to point out that this part of Antarctica was his territory. This picture was shot at dusk, resulting in the rather moody atmosphere.   Credit: Lars von Ritter Zahony (Germany) / World Ocean’s Day Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday. The striking eye of a humpback whale named Sweet Girl peers at the camera. Just four days later, she would be dead, hit by a speeding boat and one of the 20,000 whales killed by ship strikes each year. Photographer Rachel Moore’s captivating image (seen below) of Sweet Girl earned top honors at the 2025 United Nations World Oceans Day Photo Competition. Wonder: Sustaining What Sustains Us — WinnerThis photo, taken in Mo’orea, French Polynesia in 2024, captures the eye of a humpback whale named Sweet Girl, just days before her tragic death. Four days after I captured this intimate moment, she was struck and killed by a fast-moving ship. Her death serves as a heartbreaking reminder of the 20,000 whales lost to ship strikes every year. We are using her story to advocate for stronger protections, petitioning for stricter speed laws around Tahiti and Mo’orea during whale season. I hope Sweet Girl’s legacy will spark real change to protect these incredible animals and prevent further senseless loss.Credit: Rachel Moore (USA) / United Nations World Oceans Day www.unworldoceansday.org Now in its twelfth year, the competition coordinated in collaboration between the UN Division for Ocean Affairs and the Law of the Sea, DivePhotoGuide (DPG), Oceanic Global, and  the Intergovernmental Oceanographic Commission of UNESCO. Each year, thousands of underwater photographers submit images that judges award prizes for across four categories: Big and Small Underwater Faces, Underwater Seascapes, Above Water Seascapes, and Wonder: Sustaining What Sustains Us. This year’s winning images include a curious leopard seal, a swarm of jellyfish, and a very grumpy looking Japanese warbonnet. Given our oceans’ perilous state, all competition participants were required to sign a charter of 14 commitments regarding ethics in photography. Underwater Seascapes — Honorable MentionWith only orcas as their natural predators, leopard seals are Antarctica’s most versatile hunters, preying on everything from fish and cephalopods to penguins and other seals. Gentoo penguins are a favored menu item, and leopard seals can be observed patrolling the waters around their colonies. For this shot, I used a split image to capture both worlds: the gentoo penguin colony in the background with the leopard seal on the hunt in the foreground.Credit: Lars von Ritter Zahony (Germany) / United Nations World Oceans Day www.unworldoceansday.org Above Water Seascapes – WinnerA serene lake cradled by arid dunes, where a gentle stream breathes life into the heart of Mother Earth’s creation: Captured from an airplane, this image reveals the powerful contrasts and hidden beauty where land and ocean meet, reminding us that the ocean is the source of all life and that everything in nature is deeply connected. The location is a remote stretch of coastline near Shark Bay, Western Australia.Credit: Leander Nardin (Austria) / United Nations World Oceans Day www.unworldoceansday.org Above Water Seascapes — 3rd PlaceParadise Harbour is one of the most beautiful places on the Antarctic Peninsula. When I visited, the sea was extremely calm, and I was lucky enough to witness a wonderfully clear reflection of the Suárez Glacier (aka Petzval Glacier) in the water. The only problem was the waves created by our speedboat, and the only way to capture the perfect reflection was to lie on the bottom of the boat while it moved towards the glacier.Credit: Andrey Nosik (Russia) / United Nations World Oceans Day www.unworldoceansday.org Underwater Seascapes — 3rd Place“La Rapadura” is a natural hidden treasure on the northern coast of Tenerife, in the Spanish territory of the Canary Islands. Only discovered in 1996, it is one of the most astonishing underwater landscapes in the world, consistently ranking among the planet’s best dive sites. These towering columns of basalt are the result of volcanic processes that occurred between 500,000 and a million years ago. The formation was created when a basaltic lava flow reached the ocean, where, upon cooling and solidifying, it contracted, creating natural structures often compared to the pipes of church organs. Located in a region where marine life has been impacted by once common illegal fishing practices, this stunning natural monument has both geological and ecological value, and scientists and underwater photographers are advocating for its protection.

Being surrounded by millions of jellyfish, which have evolved to lose their stinging ability due to the absence of predators, was one of the most breathtaking experiences I’ve ever had.Credit: Dani Escayola (Spain) / United Nations World Oceans Day www.unworldoceansday.org Underwater Seascapes — 2nd PlaceThis shot captures a school of rays resting at a cleaning station in Mauritius, where strong currents once attracted them regularly. Some rays grew accustomed to divers, allowing close encounters like this. Sadly, after the severe bleaching that the reefs here suffered last year, such gatherings have become rare, and I fear I may not witness this again at the same spot.Credit: Gerald Rambert (Mauritius) / United Nations World Oceans Day www.unworldoceansday.org Wonder: Sustaining What Sustains Us — 3rd PlaceShot in Cuba’s Jardines de la Reina—a protected shark sanctuary—this image captures a Caribbean reef shark weaving through a group of silky sharks near the surface. Using a slow shutter and strobes as the shark pivoted sharply, the motion blurred into a wave-like arc across its head, lit by the golden hues of sunset. The abundance and behavior of sharks here is a living symbol of what protected oceans can look like.Credit: Steven Lopez (USA) / United Nations World Oceans Day www.unworldoceansday.org  Above Water Seascapes — 2nd PlaceNorthern gannets (Morus bassanus) soar above the dramatic cliffs of Scotland’s Hermaness National Nature Reserve, their sleek white bodies and black-tipped wings slicing through the Shetland winds. These seabirds, the largest in the North Atlantic, are renowned for their striking plunge-dives, reaching speeds up to 100 kph (60 mph) as they hunt for fish beneath the waves. The cliffs of Hermaness provide ideal nesting sites, with updrafts aiding their take-offs and landings. Each spring, thousands return to this rugged coastline, forming one of the UK’s most significant gannet colonies. It was a major challenge to take photos at the edge of these cliffs at almost 200 meters (650 feet) with the winds up to 30 kph (20 mph).Credit: Nur Tucker (UK/Turkey) / United Nations World Oceans Day www.unworldoceansday.org Above Water Seascapes — Honorable MentionA South Atlantic swell breaks on the Dungeons Reef off the Cape Peninsula, South Africa, shot while photographing a big-wave surf session in October 2017. It’s the crescendoing sounds of these breaking swells that always amazes me.Credit: Ken Findlay (South Africa) / United Nations World Oceans Day www.unworldoceansday.org Wonder: Sustaining What Sustains Us — Honorable MentionHumpback whales in their thousands migrate along the Ningaloo Reef in Western Australia every year on the way to and from their calving grounds. In four seasons of swimming with them on the reef here, this is the only encounter I’ve had like this one. This pair of huge adult whales repeatedly spy-hopped alongside us, seeking to interact with and investigate us, leaving me completely breathless. The female in the foreground was much more confident than the male behind and would constantly make close approaches, whilst the male hung back a little, still interested but shy. After more than 10 years working with wildlife in the water, this was one of the best experiences of my life.Credit: Ollie Clarke (UK) / United Nations World Oceans Day www.unworldoceansday.org Big and Small Underwater Faces — 2nd PlaceOn one of my many blackwater dives in Anilao, in the Philippines, my guide and I spotted something moving erratically at a depth of around 20 meters (65 feet), about 10 to 15 centimeters in size. We quickly realized that it was a rare blanket octopus (Tremoctopus sp.). As we approached, it opened up its beautiful blanket, revealing its multicolored mantle. I managed to take a few shots before it went on its way. I felt truly privileged to have captured this fascinating deep-sea cephalopod. Among its many unique characteristics, this species exhibits some of the most extreme sexual size-dimorphism in nature, with females weighing up to 40,000 times more than males.Credit: Giacomo Marchione (Italy) / United Nations World Oceans Day www.unworldoceansday.org Big and Small Underwater Faces – WinnerThis photo of a Japanese warbonnet (Chirolophis japonicus) was captured in the Sea of Japan, about 50 miles (80 kilometers) southwest of Vladivostok, Russia. I found the ornate fish at a depth of about 30 meters (100 feet), under the stern of a shipwreck. This species does not appear to be afraid of divers—on the contrary, it seems to enjoy the attention—and it even tried to sit on the dome port of my camera.Credit: Andrey Nosik (Russia) / United Nations World Oceans Day www.unworldoceansday.org Wonder: Sustaining What Sustains Us — 2nd PlaceA juvenile pinnate batfish (Platax pinnatus) captured with a slow shutter speed, a snooted light, and deliberate camera panning to create a sense of motion and drama. Juvenile pinnate batfish are known for their striking black bodies outlined in vibrant orange—a coloration they lose within just a few months as they mature. I encountered this restless subject in the tropical waters of Indonesia’s Lembeh Strait. Capturing this image took patience and persistence over two dives, as these active young fish constantly dart for cover in crevices, making the shot particularly challenging.Credit: Luis Arpa (Spain) / United Nations World Oceans Day www.unworldoceansday.org

Al Hajar Mountains in OmanL_B_Photography/Shutters​tock A section of Earth’s mantle beneath Oman appears to be unusually warm, in what researchers say may be the first known “ghost plume” – a column of hot rock emanating from the lower mantle without apparent volcanic activity on the surface. Mantle plumes are mysterious upwellings of molten rock believed to transmit heat from the core-mantle boundary to the Earth’s surface, far from the edges of tectonic plates. There are a dozen or so examples thought to occur underneath the middle of continental plates – for instance, beneath Yellowstone and the East African rift. “But these are all cases where you do have surface volcanism,” says Simone Pilia at the King Fahd University of Petroleum and Minerals in Saudi Arabia. Oman has no such volcanic clues. Pilia first came to suspect there was a plume beneath Oman “serendipitously” after he began analysing new seismic data from the region. He observed the velocity of waves generated by distant earthquakes slowed down in a cylindrical area beneath eastern Oman, indicating the rocks there were less rigid than the surrounding material due to high temperatures. Other independent seismic measurements showed key boundaries where minerals deep in the Earth change phases in a way consistent with a hot plume. These measurements suggest the plume extends more than 660 kilometres below the surface. The presence of a plume could also explain why the region has continued to rise in elevation long after tectonic compression – a geological process where the Earth’s crust is squeezed together – stopped. It also fits with models of what could have caused a shift in the movement of the Indian tectonic plate. “The more we gathered evidence, the more we were convinced that it is a plume,” says Pilia, who named the geologic feature the “Dani plume” after his son. Unmissable news about our planet delivered straight to your inbox every month. Sign up to newsletter “It’s plausible” that a plume indeed exists there, says Saskia Goes at Imperial College London, adding the study is “thorough”. However, she points out narrow plumes are notoriously difficult to detect. If it does exist, however, the presence of a “ghost plume” contained within the mantle by the relatively thick rocky layer beneath Oman would suggest there are others, says Pilia. “We’re convinced that the Dani plume is not alone.” If there are many other hidden plumes, it could mean more heat from the core is flowing directly through the mantle via plumes, rather than through slower convection, says Goes. “It has implications, potentially, for the evolution of the Earth if we get a different estimate of how much heat comes out of the mantle.” Journal referenceEarth and Planetary Science Letters DOI: 10.1016/j.epsl.2025.119467 Topics:

By TREVOR HOGG Images courtesy of Pixar. The character design of Glordon is based on a tardigrade, which is a microscopic water bear. Rather than look at the unknown as something to be feared, Pixar has decided to do some wish fulfillment with Elio, where a lonely adolescent astrophile gets abducted by aliens and is mistaken as the leader of Earth. Originally conceived and directed by Adrian Molina, the coming-of-age science fiction adventure was shepherded by Domee Shi and Madeline Sharafian, who had previously worked together on Turning Red. “Space is often seen as dark, mysterious and scary, but there is also so much hope, wonder and curiosity,” notes Shi, director of Elio. “It’s like anything is ‘out there.’ Elio captures how a lot of us feel at different points of our lives, when we were kids like him, or even now wanting to be off of this current planet because it’s just too much. For Elio, it’s a rescue. I feel that there’s something so universal about that feeling of wanting to be taken away and taken care of. To know that you’re not alone and somebody chose you and picked you up.” The character design of Glordon is based on a tardigrade, which is a microscopic water bear. There is a stark contrast between how Earth and the alien world, known as the Communiverse, are portrayed. “The more we worked with the animators on Glordon and Helix, they began to realize that Domee and I respond positively when those [alien] characters are exaggerated, made cute, round and chubby,” states Sharafian, director of Elio. “That automatically started to differentiate the way the Earth and space feel.” A certain question had to be answered when designing the United Nations-inspired Communiverse. “It was coming from a place of this lonely kid who feels like no one wants him on Earth,” Shi explains. “What would be heaven and paradise for him? The Communiverse was built around that idea.” A sense of belonging is an important theme. “It’s also inspired by Adrian Molina’s backstory, and our backstories too, of going to animation college,” Sharafian remarks. “For the first time, we said, ‘This is where everybody like me is!’” Green is the thematic color for Elio. Visual effects are an important storytelling tool. “Especially, for our movie, which is about this boy going to this crazy incredible world of the Communiverse,” Shi observes. “It has to be dazzling and look spectacular on the big screen and feel like paradise. Elio is such a visual feast, and you do feel like, ‘I want to stay here no matter what. I can’t believe that this place even exists.’ Visual effects are a powerful tool to help you feel what the characters are feeling.” A wishlist became a reality for the directors. “Claudia Chung Sanii [Visual Effects Supervisor] gave Domee and me carte blanche for wish fulfillment for ourselves,” Sharafian remarks. “What do you want Elio’s outfit in space to look like? It was a difficult costume, but now when we watch the movie, we’re all so proud of it. Elio looks fabulous, and he’s so happy to be wearing that outfit. Who would want to take that off?” The Communiverse was meant to feel like a place that a child would love to visit and explore. Methodology rather than technology went through the biggest change for the production. “The Communiverse is super complex and has lots of moving pieces. But there’s not much CG can’t do anymore,” notes Claudia Chung Sanii. “Elemental did effects characters. We did long curly hair, dresses, capes, water and fire. What we hadn’t done before was be a part of that design process. How do we get lighting into layout? How do we see the shaders in animation in layout? The tools department was working on a software called Luna which does that. I went to the tools department and asked, ‘Can I play around with it?’ They were like, ‘Okay. But it’s not ready yet.’ Tools will basically be bringing RenderMan and an interactive lighting workflow to the pipeline across all of these DCCs. Because we light in Katana, you can’t get back upstream. The conceit that we were dipping our toe in on Elio was, ‘Whatever you do in lighting, anyone on the pipeline can see it.’” The influence of microscopic forms and macro photography grounded the Communiverse in natural phenomena. The variety in the Communiverse is a contrast to the regimented world on the military base. There were no departmental borders, in particular with cinematography. “We had our layout and lighting DPs start on the same day. Derek Williams wouldn’t shoot anything without Jordan Rempel, our lighting DP, seeing it,” Sanii states. “Jordan would drop in lighting and start doing key lighting as Derek’s team was laying out. It wasn’t like you had to hit the render button, wait for the render to come up and go, ‘Oh, my god, it’s dark! I didn’t know that it was nighttime.’” A new term was adopted. “Meredith Hom [Production Manager] and I pulled the entire crew and leadership into this mental concept that we called the ‘college project.’ For some of us, college was a time when we didn’t have titles and crafts. You begged, borrowed and stole to hit that deadline. So much of our world has become linear in our process that I wanted to break that down to, ‘No. We’re all working together. The scope of this film is too large for us to wait for each other to finish our piece. If this person is slammed, fine. Figure out a different idea to do it with what tools you have.’” Directors Domee Shi and Madeline Sharafian are drawn to chubby, exaggerated and cute characters. Forgoing the word ‘no’ led to the technology breaking down. “I remember times when crowds [department] is dressing all of the aliens and because of forgetting to constrain it to the Communiverse, they all show up at the origin, and you’re going, ‘Why is there a whole party going on over there?’” Sanii laughs. “On Elio, it was always forward. There were no rules about locking things down or not installing over the weekend. It was always like, ‘Put it all in, and we’ll deal with it on Monday.’ There would be some funny stuff. We never QC’d something before walking it into the room. Everyone saw how the sausage was made. It was fun and not fun for Harley Jessup [Production Designer] because sometimes there would be a big thing in the middle screen, and he would say, ‘Is that finished?’ There was no way we could get through this film if we kept trying to fix the thing that broke.” An aerial image of Elio as he attempts to get abducted by aliens. Part of the design of the Coummuniverse was inspired by Chinese puzzle balls. A former visual effects art director at ILM, Harley Jessup found his previous experiences on projects like Innerspace to be helpful on Elio. “I liked that the directors wanted to build on the effects films from the 1980s and early 1990s,” reflects Jessup. “I was there and part of that. It was fun to look back. At the time, the techniques were all practical, matte paintings and miniatures, which are fun to work with, but without the safety net of CG. One thing Dennis Muren [VES] was keen on, was how people see things like the natural phenomenon you might see in a microscopic or macro photography form. We were using that. I was looking at the mothership of Close Encounters of the Third Kind, which Dennis shot when he was a young artist. It was nice to be able to bring all of that history to this film.” Earth was impacted by a comment made by Pete Docter (CCO, Pixar). “He said, ‘The military base should feel like a parking lot,” Jessup reveals. “You should know why Elio wants to be anywhere else. And the Communiverse needs to be inviting. We built a lot of contrast into those two worlds. The brutalist architecture on the military base, with its hard edges and heavy horizontal forms close to the earth, needed to be harsh but beautiful in its own way, so we tried for that. The Communiverse would be in contrast and be all curves, translucent surfaces and stained-glass backlit effects. Things were wide open about what it could be because each of the aliens are from a different climate and gravity. There are some buildings that are actually upside down on it, and the whole thing is rotating inside like clockwork. It is hopefully an appealing, fun world. It’s not a dystopian outer space.” Exploring various facial expressions for Elio. A tough character to get right was Aunt Olga, who struggles to be the guardian of her nephew. Character designs of Elio and Glordon. which shows them interacting with each other. Architecture was devised to reflect the desired tone for scenes. “In the Grand Assembly Hall where each alien has a desk and booth, the booth is shaped like an eyelid that can close or open,” Jessup explains. “It increases the feeling that they’re evaluating and observing Elio and each of the candidates that have come to join the Communiverse.” A couple of iconic cinematic franchises were avoided for aesthetic reasons. “As much as I love Star Wars and Star Trek, we wanted to be different from those kinds of aliens that are often more humanoid.” Ooooo was the first alien to be designed. “We did Ooooo in collaboration with the effects team, which was small at that time. She was described as a liquid supercomputer. We actually used the wireframe that was turning up and asked, what if it ended up being this network of little lights that are moving around and can express how much she was thinking? Ooooo is Elio’s guide to the Communiverse; her body would deform, so she could become a big screen or reach out and pluck things. Ooooo has an ability like an amoeba to stretch.” Flexibility is important when figuring out shot design. “On Elio, we provided the layout department with a rudimentary version of our environments,” states David Luoh, Sets Supervisor. “It might be simple geometry. We’re not worried necessarily about shading, color and material yet. Things are roughly in place but also built in a way that is flexible. As they’re sorting out the camera and testing out staging, they can move elements of the set around. Maybe this architectural piece needs to be shifted or larger or smaller. There was a variation on what was typically expected of set deliveries of environments to our layout department. That bar was lowered to give the layout department something to work with sooner and also with more flexibility. From their work we get context as to how we partner with our art and design department to build and finalize those environments.” Regional biomes known as disks are part of the Communiverse. “There are aquatic, lush forest, snow and ice, and hot lava disks,” Luoh remarks. “The hot disk is grounded in the desert, volcanic rock and lava, while for the lush disk we looked at interesting plant life found in the world around us.” The Communiverse is a complex geometric form. “We wanted these natural arrangements of alien districts, and that was all happening on this twisting and curving terrain in a way that made traditional dressing approaches clunky. Oftentimes, you’re putting something on the ground or mounted, and the ground is always facing upward. But if you have to dress the wall or ceiling, it becomes a lot more difficult to manipulate and place on something with that dynamic and shape. You have stuff that casts light, is see-through and shifting over time. Ooooo is a living character that looks like electronic circuitry that is constantly moving, and we also have that element in the walls, floors and bubble transport that carry the characters around.” Sets were adjusted throughout the production. “We try to anticipate situations that might come up,” Luoh states. “What if we have a series of shots where you’re getting closer and closer to the Communiverse and you have to bridge the distance between your hero and set extension background? There is a partnership with story, but certainly with our layout camera staging department. As we see shots come out of their work, we know where we need to spend the time to figure out, are we going to see the distant hills in this way? We’re not going to build it until we know because it can be labor-intensive. There is a responsiveness to what we are starting to see as shots get made.” Combining the familiar into something unfamiliar was a process. “There was this curation of being inspired by existing alien sci-fi depictions, but also reaching back into biological phenomena or interesting material because we wanted to ground a lot of those visual elements and ideas in something that people could intuitively grasp on to, even if they were combined or arranged in a way that is surprising, strange and delightful.”

In the past, we've featured year-end roundups of cool science stories we (almost) missed. This year, we're experimenting with a monthly collection. May's list includes a nifty experiment to make a predicted effect of special relativity visible; a ping-pong playing robot that can return hits with 88 percent accuracy; and the discovery of the rare genetic mutation that makes orange cats orange, among other highlights. Special relativity made visible Credit: TU Wien Perhaps the most well-known feature of Albert Einstein's special theory of relativity is time dilation and length contraction. In 1959, two physicists predicted another feature of relativistic motion: an object moving near the speed of light should also appear to be rotated. It's not been possible to demonstrate this experimentally, however—until now. Physicists at the Vienna University of Technology figured out how to reproduce this rotational effect in the lab using laser pulses and precision cameras, according to a paper published in the journal Communications Physics. They found their inspiration in art, specifically an earlier collaboration with an artist named Enar de Dios Rodriguez, who collaborated with VUT and the University of Vienna on a project involving ultra-fast photography and slow light. For this latest research, they used objects shaped like a cube and a sphere and moved them around the lab while zapping them with ultrashort laser pulses, recording the flashes with a high-speed camera. Getting the timing just right effectively yields similar results to a light speed of 2 m/s. After photographing the objects many times using this method, the team then combined the still images into a single image. The results: the cube looked twisted and the sphere's North Pole was in a different location—a demonstration of the rotational effect predicted back in 1959.

Chimpanzees are known to "drum" on the roots of trees as a means of communication, often combining that action with what are known as "pant-hoot" vocalizations (see above video). Scientists have found that the chimps' drumming exhibits key elements of musical rhythm much like humans, according to  a paper published in the journal Current Biology—specifically non-random timing and isochrony. And chimps from different geographical regions have different drumming rhythms. Back in 2022, the same team observed that individual chimps had unique styles of "buttress drumming," which served as a kind of communication, letting others in the same group know their identity, location, and activity. This time around they wanted to know if this was also true of chimps living in different groups and whether their drumming was rhythmic in nature. So they collected video footage of the drumming behavior among 11 chimpanzee communities across six populations in East Africa (Uganda) and West Africa (Ivory Coast), amounting to 371 drumming bouts. Their analysis of the drum patterns confirmed their hypothesis. The western chimps drummed in regularly spaced hits, used faster tempos, and started drumming earlier during their pant-hoot vocalizations. Eastern chimps would alternate between shorter and longer spaced hits. Since this kind of rhythmic percussion is one of the earliest evolved forms of human musical expression and is ubiquitous across cultures, findings such as this could shed light on how our love of rhythm evolved.

Distinctive styles of two jazz greats Jazz lovers likely need no introduction to Joe Pass and Wes Montgomery, 20th century guitarists who influenced generations of jazz musicians with their innovative techniques. Montgomery, for instance, didn't use a pick, preferring to pluck the strings with his thumb—a method he developed because he practiced at night after working all day as a machinist and didn't want to wake his children or neighbors. Pass developed his own range of picking techniques, including fingerpicking, hybrid picking, and "flat picking." Chirag Gokani and Preston Wilson, both with Applied Research Laboratories and the University of Texas, Austin, greatly admired both Pass and Montgomery and decided to explore the underlying the acoustics of their distinctive playing, modeling the interactions of the thumb, fingers, and pick with a guitar string. They described their research during a meeting of the Acoustical Society of America in New Orleans, LA. Among their findings: Montgomery achieved his warm tone by playing closer to the bridge and mostly plucking at the string. Pass's rich tone arose from a combination of using a pick and playing closer to the guitar neck. There were also differences in how much a thumb, finger, and pick slip off the string:  use of the thumb (Montgomery) produced more of a "pluck" compared to the pick (Pass), which produced more of a "strike." Gokani and Wilson think their model could be used to synthesize digital guitars with a more realistic sound, as well as helping guitarists better emulate Pass and Montgomery. Sounds of an ancient underground city Credit: Sezin Nas Turkey is home to the underground city Derinkuyu, originally carved out inside soft volcanic rock around the 8th century BCE. It was later expanded to include four main ventilation channels (and some 50,000 smaller shafts) serving seven levels, which could be closed off from the inside with a large rolling stone. The city could hold up to 20,000 people and it  was connected to another underground city, Kaymakli, via tunnels. Derinkuyu helped protect Arab Muslims during the Arab-Byzantine wars, served as a refuge from the Ottomans in the 14th century, and as a haven for Armenians escaping persecution in the early 20th century, among other functions. The tunnels were rediscovered in the 1960s and about half of the city has been open to visitors since 2016. The site is naturally of great archaeological interest, but there has been little to no research on the acoustics of the site, particularly the ventilation channels—one of Derinkuyu's most unique features, according to Sezin Nas, an architectural acoustician at Istanbul Galata University in Turkey.  She gave a talk at a meeting of the Acoustical Society of America in New Orleans, LA, about her work on the site's acoustic environment. Nas analyzed a church, a living area, and a kitchen, measuring sound sources and reverberation patterns, among other factors, to create a 3D virtual soundscape. The hope is that a better understanding of this aspect of Derinkuyu could improve the design of future underground urban spaces—as well as one day using her virtual soundscape to enable visitors to experience the sounds of the city themselves. MIT's latest ping-pong robot Robots playing ping-pong have been a thing since the 1980s, of particular interest to scientists because it requires the robot to combine the slow, precise ability to grasp and pick up objects with dynamic, adaptable locomotion. Such robots need high-speed machine vision, fast motors and actuators, precise control, and the ability to make accurate predictions in real time, not to mention being able to develop a game strategy. More recent designs use AI techniques to allow the robots to "learn" from prior data to improve their performance. MIT researchers have built their own version of a ping-pong playing robot, incorporating a lightweight design and the ability to precisely return shots. They built on prior work developing the Humanoid, a small bipedal two-armed robot—specifically, modifying the Humanoid's arm by adding an extra degree of freedom to the wrist so the robot could control a ping-pong paddle. They tested their robot by mounting it on a ping-pong table and lobbing 150 balls at it from the other side of the table, capturing the action with high-speed cameras. The new bot can execute three different swing types (loop, drive, and chip) and during the trial runs it returned the ball with impressive accuracy across all three types: 88.4 percent, 89.2 percent, and 87.5 percent, respectively. Subsequent tweaks to theirrystem brought the robot's strike speed up to 19 meters per second (about 42 MPH), close to the 12 to 25 meters per second of advanced human players. The addition of control algorithms gave the robot the ability to aim. The robot still has limited mobility and reach because it has to be fixed to the ping-pong table but the MIT researchers plan to rig it to a gantry or wheeled platform in the future to address that shortcoming. Why orange cats are orange Credit: Astropulse/CC BY-SA 3.0 Cat lovers know orange cats are special for more than their unique coloring, but that's the quality that has intrigued scientists for almost a century. Sure, lots of animals have orange, ginger, or yellow hues, like tigers, orangutans, and golden retrievers. But in domestic cats that color is specifically linked to sex. Almost all orange cats are male. Scientists have now identified the genetic mutation responsible and it appears to be unique to cats, according to a paper published in the journal Current Biology. Prior work had narrowed down the region on the X chromosome most likely to contain the relevant mutation. The scientists knew that females usually have just one copy of the mutation and in that case have tortoiseshell (partially orange) coloring, although in rare cases, a female cat will be orange if both X chromosomes have the mutation. Over the last five to ten years, there has been an explosion in genome resources (including complete sequenced genomes) for cats which greatly aided the team's research, along with taking additional DNA samples from cats at spay and neuter clinics. From an initial pool of 51 candidate variants, the scientists narrowed it down to three genes, only one of which was likely to play any role in gene regulation: Arhgap36. It wasn't known to play any role in pigment cells in humans, mice, or non-orange cats. But orange cats are special; their mutation (sex-linked orange) turns on Arhgap36 expression in pigment cells (and only pigment cells), thereby interfering with the molecular pathway that controls coat color in other orange-shaded mammals. The scientists suggest that this is an example of how genes can acquire new functions, thereby enabling species to better adapt and evolve.

Not a Roman "massacre" after all Credit: Martin Smith In 1936, archaeologists excavating the Iron Age hill fort Maiden Castle in the UK unearthed dozens of human skeletons, all showing signs of lethal injuries to the head and upper body—likely inflicted with weaponry. At the time, this was interpreted as evidence of a pitched battle between the Britons of the local Durotriges tribe and invading Romans. The Romans slaughtered the native inhabitants, thereby bringing a sudden violent end to the Iron Age. At least that's the popular narrative that has prevailed ever since in countless popular articles, books, and documentaries. But a paper published in the Oxford Journal of Archaeology calls that narrative into question. Archaeologists at Bournemouth University have re-analyzed those burials, incorporating radiocarbon dating into their efforts. They concluded that those individuals didn't die in a single brutal battle. Rather, it was Britons killing other Britons over multiple generations between the first century BCE and the first century CE—most likely in periodic localized outbursts of violence in the lead-up to the Roman conquest of Britain. It's possible there are still many human remains waiting to be discovered at the site, which could shed further light on what happened at Maiden Castle.

Ancient Roman structures have always been a major attraction for both common people and researchers. The durability of those magnificent architectural feats like the Pantheon of Rome has made researchers curious about how they are standing tall nearly after two thousand years of the height of the Roman empire. While The longevity of these structures can be attributed largely to Roman concrete, question still prevails about the speciality and the materials used in the concrete itself. Ingredients of Roman concreteAccording to the study published in the journal Science Advances, an international team of researchers led by the Massachusetts Institute of Technology (MIT) found that not only are the materials slightly different from what we may have thought, but the techniques used to mix them were also different.One key ingrediant was pozzolan, or ash. The Romans used ash from the volcanic beds of the Italian city Pozzuoli and shipped it all over the empire. The silica and alumina in the ash react with lime and water in a pozzolanic reaction at ambient temperatures, resulting in a stronger, longer lasting concrete.Another key ingredient is lime clasts, or small chunks of quicklime.These clasts give Roman concrete its self-healing capability. Concrete weathers and weakens over time, but water can infiltrate its cracks and reach the clasts. When they react with the water, the clasts create crystals called calcites that fill in the cracks.Difference with modern day cementThe high-temperature kiln process used today to make modern day Portland cement, grinds all materials into fine powder. It eliminates the lime clasts which results into the lack of the self-healing properties of Roman cement.The Romans utilized a method known as hot mixing, which involves combining quicklime with pozzolan, water and other ingredients and then heating them up. The MIT team found that this method helps unlock the lime clasts' self-healing abilities, and can result in faster setting than cement made with a quicklime-water solution called slaked lime.
