Photo by ANDREW CABALLERO-REYNOLDS/AFP via Getty Images Last night a commercial airliner carrying 64 passengers collided with a U.S. Army Black Hawk helicopter over the Potomac River near Reagan International Airport in Washington D.C. This morning authorities said theyd pulled 27 bodies from the crash. They dont expect to find any survivors. The plane was a 20-year-old Bombardier CRJ700 on its way from Wichita, Kansas, and approaching its runway at the airport. The Black Hawk was flying a training mission out of nearby Fort Belvoir. The night was clear and both FAA and Army officials have told the public that there were no indications of malfunctions or miscommunications. The jet was flying north towards its runway. The helicopter was coming south from the fort. They collided with each other just after 9 p.m. on Wednesday. The crash was captured on video and uploaded to social media after it occurred and the debris field spread across the water of the Potomac. Recovery efforts are ongoing. The hunt for an explanation or someone to blame has begun. In a post on Truth Social last night after midnight, President Donald Trump suggested that air traffic controllers were at fault.The airplane was on a perfect and routine line of approach to the airport, Trump said on Truth Social. The helicopter was going straight at the airplane for an extended period of time. It is a CLEAR NIGHT, the lights on the plane were blazing, why didnt the helicopter go up or down, or turn. Why didnt the control tower tell the helicopter what to do instead of asking if they saw the plane. This is a bad situation that looks like it should have been prevented. NOT GOOD!!! The tragedy comes less than a month after the start of his presidency and just days after the Senate confirmed Pete Hegseth as the Secretary of Defense. The Federal Aviation Administration is, at the moment, leaderless.Michael Whitaker assumed the post in 2023 and announced his intention to resign back in December following Trumps victory. Whitaker was a vocal critic of SpaceX and had chastised Elon Musks space program for skirting safety regulations. The only way to bring them to heel, he said, was to levy massive fines. Musk told him to resign from the FAA in a post on X. Whitaker did just that, leaving his post on January 20. At the moment, its unclear who is running the FAA. The administrator is a post that requires Senate confirmation but Trump hasnt named a successor. Former FAA official Chris Rocheleau returned to the agency recently and sources inside D.C. have told some news outlets that hes the de-facto leader. So the FAA is officially leaderless after the first major mid-air collision in the U.S. in 16 years. Adding to the confusion is the federal hiring freeze, which Trump enacted by dictate and has been unevenly applied and widely misunderstood. Though the executive order appeared to have a carve-out for officials related to safety, there was mass confusion about whether or not that involved air traffic controllers.On January 22, a week before the crash, ranking members of the House Committee on Transportation and Infrastructure called out the hiring freeze in a joint statement. Hiring air traffic controllers is the number one safety issue according to the entire aviation industry. Instead of working to improve aviation safety and lower costs for hardworking American families, the Administration is choosing to spread bogus DEI claims to justify this decision, Rick Larsen (D-WA) said in the statement. Im not surprised by the Presidents dangerous and divisive actions, but the Administration must reverse course. Lets get back to aviation safety and allow the FAA to do its job protecting the flying public.On /r/ATC, a subreddit dedicated to air traffic controllers, members vented their confusion and asked what was going on with jobs. Anybody else notice that all ATC job postings on usajobs have been removed besides DOD positions? Ive been told that all vacancy announcements that closed before today will still go through the selection process. Anyone else heard anything? One Redditor said three days ago. Conditions at some federally-run aviation towers are so bad that theyll soon be completely unstaffed. According to a memo fromAirport Manager Gretchen Kelly, the San Carlos Federal Contract Tower will have absolutely no ATC services starting in February. The FAA has awarded a new contract for air traffic services at SQL to Robinson Aviation, the letter said. However, the contract does not include locality pay to account for the high cost of living in the San Francisco Bay Area. As a result, none of the air traffic controllers decided to stick around The FAA was formed in 1958, in part, because a series of mid-air collisions convinced Washington and the public that a federal agency was needed to regulate the skies.Daily NewsletterYou May Also Like By AJ Dellinger Published January 29, 2025 By Matt Novak Published January 29, 2025 By Matt Novak Published January 28, 2025 By Matt Novak Published January 27, 2025 By AJ Dellinger Published January 24, 2025 By Lucas Ropek Published January 24, 2025

A plot of land on Frther Street in Nuremberg is being developed to close a construction gap in the backyard, creating new residential space. A three-story residential building with three units was constructed, oriented towards the courtyard. The building fits into the plot's volume, which is surrounded by buildings on three sides. As a result, a shared courtyard is established between the existing front house and the new rear house, available for use by all residents. For the new rear house, large faade openings were chosen to ensure sufficient lighting for the north-facing apartments in this densely built-up area.Save this picture!Save this picture!Save this picture!Access to the residential units is via an external, freestanding staircase. The deep stair landings also serve as open areas for the residents, offering views of the courtyard. Each of the three residential units follows the same floor plan: a single room, which is divided by a rear addition containing the bathroom, dressing area, and storage space. The sleeping area can be separated from the living and dining area by a curtain. A long bench at the window facing the courtyard provides storage space and a flexible seating option for the kitchen-dining area.Save this picture!Save this picture!Save this picture!The building features a faade cladding made of bare aluminum in a jagged form, which strongly distinguishes it from the surrounding context, giving it an independent architectural identity. This light-colored faade reflects onto the courtyard, adding extra brightness to the space. At the same time, it also reflects the colors of the surroundings and the sky, changing slightly each day.Save this picture!Due to war-related soil embankments, the building had to be founded on micro-drilled piles. The construction was built as a solid structure using high-hole bricks with a ventilated, cladding faade. The ceilings consist of prefabricated elements, similar to the stairs. As a color accent, the balustrades of the access area and the wood-aluminum sliding windows are painted green. This color can also be found as an accent in the visible screed of the apartments and in small details such as the cabinetry and bathroom tiles.Save this picture!Project gallerySee allShow lessAbout this officePublished on January 30, 2025Cite: "Backyard House / super future collective" 30 Jan 2025.

Most of us hope well be healthy into our late 80s or early 90s and then die peacefully in our sleep, preferably after a wonderful evening with loved ones. But thats rarely the way it works out. All too often, our later years are plagued with ill health.Life expectancy has been steadily increasing throughout the world since 1900, but those gains have not been matched by equivalent gains in health, says Armin Garmany, a researcher who studies regenerative medicine at the Mayo Clinic.People outlive their good health by an average of 9.6 years 12 years for those who live in the U.S. according to research by Garmany and Andre Terzig, a pioneer in the field of regenerative medicine, also at Mayo.Garmany and Terzig were the first to quantify the gap, but the idea has been around for decades. In a paper published in Science in 1987, John Rowe and Robert Kahn introduced the term health span, a measure not of how long we live but of how long we live without significant health problems. Since then, scientists have increasingly embraced the concept and are working to close the gap.Addressing Shorter Health SpansRecent advances in medicine, both surgical and pharmaceutical, have made aging much easier, dramatically improving the quality of life of older people. Joint replacements, stents, and medicines for controlling cholesterol blood pressure, and maintaining heart function are just a few examples.But these therapies do not eliminate illnesses; they just make them easier to live with. And they come with a cost, says Kenneth Boockvar, geriatrics director at the Integrative Center for Aging Research at the University of Alabama at Birmingham. The trade-off is that we face a life of taking medicines, getting injections, and interacting with the healthcare system. We may be maintaining our health, he says, but it is taking some work.Garmany and Terzig think we can do better. In a 2021 paper, they describe several new approaches that would go much further toward eliminating illness. For example, as more patient data becomes available, scientists can use artificial intelligence to analyze that data and identify people at risk for developing disease, enabling physicians to intervene before people become ill, or as Terzig puts it, extinguish the fire before the fire even starts.Another approach involves targeting aging cells and preserving healthy cells, something called anti-senescence. And then theres regenerative medicine, therapies that aim to restore the form and function of diseased or aging organs using stem cells or other methods. Advances in these areas open the possibility of not only mitigating the symptoms of disease but ultimately finding cures, says Garmany.Preventing the GapHowever, closing the health span/lifespan gap is not just about cutting-edge technologies. Prevention plays a huge role, too. We can reduce the chances of getting those illnesses that so often plague our later years by eating well, exercising, maintaining a healthy weight, and avoiding behaviors that put us at risk, such as smoking and excessive alcohol use, says Boockvar.The consequences may come late, but prevention starts early and is often a matter of public health. Terzig points out that the foundation of a healthy life begins with programs that get children off to a healthy start, as well as education, both at school and at home, about healthy living.Maximizing Good HealthThe steady increase in lifespan over the past two centuries is partly due to factors such as better nutrition, sanitation, neonatal healthcare, vaccines, antibiotics, reductions in poverty, and an emphasis on disease prevention. Maximizing the years of good health will also require extending these improvements in public health to more of society.We have a healthcare I hesitate to say system because it doesnt feel like a system to me that is largely commercial, and insurance is not available to everyone, says Boockvar. People often defer healthcare because of the cost or because they dont have access to care. A federal campaign to provide basic healthcare to everybody could narrow the disparities.If we are to narrow the gap between lifespan and health span, well need to focus on all these approaches new technologies, improved public health, greater access to care, timely interventions, and better prevention.The impact of medicine, even during my career, has advanced more than I would have expected, says Boockvar. Hes hopeful that this progress will continue until were able to enjoy robust health until the moment we die.Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.

NewsAnimalsFeeding sharks junk food takes a toll on their healthA diet of poor-quality scraps is changing the behavior and physiology of blacktip reef sharks Blacktip reef sharks (Carcharhinus melanopterus) on the island of Mo'orea receive food scraps from tourists, but it may not be great for their long-term health.Johann MourierBy Jake Buehler11 seconds agoIn general, sharks have a reputation as swimming garbage cans that unflinchingly dine on whatever they can fit in their jaws. But in French Polynesia, blacktip reef sharks that frequent places where tourists toss them low-quality scraps are taking a hit to their metabolic and reproductive health, researchers report December 24 in Animal Conservation.Around the world, snorkeling or diving tourists who want to see sharks in their natural habitat may lure them with food. A particularly popular location for shark feeding is Moorea, a small island near Tahiti.On the sand bank shallows, tourists in boats and kayaks congregate to see the sharks and stingrays, tossing them everything from frozen squid to human food scraps.

Nature, Published online: 29 January 2025; doi:10.1038/d41586-025-00199-9Methanol is metabolized into the natural gas methane by many microbes living under Earths surface, but its source has been unclear. It emerges that some bacteria convert formate molecules into methanol and transfer it to methane-metabolizing archaea. Such a metabolic transfer of methanol between microbes has not been reported before.
