Designed to enhance manufacturing capabilities in harsh environments, the initiative prioritized battle damage repair and the production of large metal components. SPEE3Ds strong performance during the trial showcased its ability to tackle cold-weather manufacturing challenges effectively.Byron Kennedy, CEO of SPEE3D said, The positive results of the Point of Need Challenge demonstrate that the XSPEE3D can print metal parts from anywhere and in most weather conditions with the same successful outcomes.He noted prior collaborations with the Australian Army, where the technology demonstrated its effectiveness in the extreme heat of the rugged Australian bush. The recent trial, he added, confirms its capability to perform equally well in sub-zero environments, supporting the DoDs efforts to enhance manufacturing capabilities in remote and austere locations.Proven performance in extreme cold environmentsAmong the 11 organizations chosen for the PONC, SPEE3D participated in the Staying in the Fight Challenge. Partnering with LIFT, a Manufacturing Innovation Institute based in Detroit, SPEE3D tested its XSPEE3D printer at the Cold Regions Research and Engineering Laboratory (CRREL) in Hanover, New Hampshire.Temperatures during the trial dipped as low as -20C (4F), yet the system managed to print a variety of components, including tools, replacement parts for military vehicles, and copper samples. Engineers introduced additional parts during the live exercise, demonstrating the systems adaptability in real-time scenarios.XSPEE3D set up and ready for cold testing in CRREL location. Photo via SPEE3D.Results from months of testing at the New Jersey Institute of Technology (NJIT) confirmed that the components met material strength standards, including yield and ultimate tensile strength, with minimal changes in ductility.These findings validated the EMUs ability to manufacture parts in extreme environments without compromising quality. Such performance underscores the systems potential to redefine manufacturing in harsh conditions, providing organizations with greater control over their operations.Noel Mack, Chief Technology Officer, LIFT, praised the efforts of participants, emphasizing the significance of their contributions stating, The Point of Need Challenge winners have proven to be champions of research and innovation and are helping drive the United States militarys technological advantage through the latest in advanced materials and manufacturing process technologies.He further explained, that SPEE3Ds work demonstrated that the technology to support warfighters not only exists but can also be deployed closer to where it is needed, enabling successful mission execution.US soldiers with copper part printed with XSPEE3D in CRREL location. Photo via SPEE3D.Addressing logistical challenges in remote manufacturingSourcing parts in cold environments often presents significant logistical hurdles, from lengthy lead times to high transportation costs.SPEE3Ds EMU directly tackles these issues by enabling on-site manufacturing, reducing downtime, and ensuring uninterrupted operations in critical settings. Its role in overcoming such obstacles during the PONC trial cements its position as a vital asset for defense and other industries operating in remote locations.Housed in two 20-foot containers with twist locks, the EMU integrates the XSPEE3D printer with the SPEE3Dcell post-processing unit. This mobile manufacturing solution offers end-to-end capabilities, including heat treatment, CNC milling, and quality testing.SPEE3D technician reviews part printed with XSPEE3D in CRREL location.

Can a wildlife management area support both wildlife and human recreational opportunities, particularly hunting?Canada Geese (Branta canadensis) take to the air over the Delmarva peninsula. (Credit: Alexego01, ... [+] via GoodFon)Alexego01 via a Creative Commons licenseCanada geese are more wily than most people think. For example, a new study by a team of researchers at Pennsylvania State University reports that Canada geese, Branta canadensis, seem to understand when and where hunters will arrive, and yet they still refuse to leave their favourite haunts, despite the risks. This studys findings aligns with a previous study conducted in Chicago (more here).Canada geese many of which are non-migratory in Pennsylvania account for about half of the total harvest of waterfowl within the state of Pennsylvania, said the studys senior author, Frances Buderman, an assistant professor of quantitative wildlife ecology. However, we know very little about how resident geese respond to hunting pressure on Middle Creek and Pymatuning Wildlife Management Areas (WMAs) and similar areas across the country.Pymatuning WMA comprises 9,661-acres in the northwest corner of Pennsylvania and Middle Creek WMA comprises 6,207-acres in the southeast. Both WMAs are operated and maintained by Pennsylvania Game Commission specifically to increase game species and to create hunting opportunities. These WMAs are comprised of cropland, forest, lake and wetlands that serve to provide refuge for geese that may help alleviate the effects of hunting. The agency additionally maintains stationary waterfowl hunting blinds which are allocated to duck and goose hunters using a lottery system.Because these WMAs are designed to provide two conflicting services to maintain wildlife habitat and to offer recreation, including hunting opportunities that may scare the birds away no one really knows how the resident geese perceive the situation. This is where Professor Buderman and collaborators enter the picture.MORE FOR YOUWe looked at whether hunting pressure on these sites is causing geese to leave the WMAs, Professor Buderman said about the study.To monitor the movements of the geese, Professor Buderman and collaborators trapped a total of 134 female geese and fitted them with GPS collars to track their movements over two hunting seasons. During that time, the researchers collected and analyzed 7.4 million observed locations provided by the 134 geese.The data revealed that resident geese abandoned location where hunters were active for short periods of time to avoid being killed, but overall, they maintained their long-term fidelity to the WMAs themselves. This finding surprised the researchers and ran counter to findings from similar waterfowl studies, according to Professor Buderman.Professor Buderman and collaborators explained in their study (ref) that the geese are probably relying on both a cognitive map of risks a landscape of fear as well as an awareness of when the danger is present a schedule of fear to move around their environment and to make decisions about the trade-offs between refuges, resources and habitats.Further, the studys findings suggest that if geese find sufficient refuge pockets of habitat where they can remain hidden from hunters they are not likely to abandon a WMA at all.Many aspects of wildlife biology are simultaneously centered on two types of objectives: supporting the population of the animal and supporting human activities, such as maximizing recreational opportunities, which can include hunting, Professor Buderman explained. It turns out the WMAs, which are being managed by the Game Commission for hunted species, including Canada geese, really are serving their twofold purpose to provide habitat for the species throughout its life-cycle and to provide opportunities for hunters.Hunter satisfaction is important to agencies like the Game Commission, Professor Buderman pointed out. Satisfied hunters support wildlife and habitat programs, which ultimately support the conservation of hunted and non-hunted species.In terms of waterfowl hunters nationwide, theyre some of the biggest contributors through their required purchase of a federal Duck Stamp, Professor Buderman said.According to the US Fish and Wildlife service, the Federal Duck Stamp program is amongst the most successful conservation tools ever created to protect habitat for birds and other wildlife. Ninety-eight percent of the purchase price of a duck stamp goes directly to acquire and protect wetlands, to help purify water, aid in flood control, reduce soil erosion and sedimentation, and enhance outdoor recreation opportunities. Since 1934, over $1.1 billion dollars have been raised from sales of Federal Duck Stamps to conserve over 6 million acres of land within the National Wildlife Refuge System. In addition to hunters, birdwatchers, conservationists, stamp collectors and others also purchase the Duck Stamp stamp in support of habitat conservation.Source:Karen E. Beatty, Nathaniel R.

(Photo by Jeff Bottari/Zuffa LLC)Zuffa LLCWhittaker discussed the possibility on a recent episode of his MMArcade podcast. Whittaker was asked by his co-host Jonny Roses who would win if Pantoja moved up in weight to challenge Merab for his bantamweight title.I love Pantoja, but Merab murders him, murders him, Whittaker said. If Pantoja goes up to Merab, Merab murders him...bad. I like Pantoja. Hes won me over a lot. Hes killed the division, but I dont think Merab is where his double belt lies.Dvalishvili would seemingly be a terrible matchup for Pantoja. While cardio isn't an Achilles' heel for Pantoja, there may be no one in the history of the sport with a deeper gas tank than Dvalishvili.MORE FOR YOUINGLEWOOD, CALIFORNIA - JANUARY 18: Merab Dvalishvili of Georgia reacts after a decision victory ... [+] against Umar Nurmagomedov of Russia in the UFC bantamweight championship fight during the UFC 311 event at Intuit Dome on January 18, 2025 in Inglewood, California. (Photo by Jeff Bottari/Zuffa LLC)Zuffa LLCWhat we saw the Georgian do against Nurmagomedov at UFC 311 was legendary. Dvalishvili's pace, wrestling, and strength could be too much for the Brazilian.Against Pantoja, Dvalishvili would enjoy something that he never gets at bantamweight: a size advantage.Dvalishvili is not only an inch taller at 5-foot-6, but he's also a naturally thicker-built man who would almost certainly be the bigger guy in the Octagon.If Sean O'Malley and Nurmagomedov couldn't get the better of Dvalishvili in the stand-up, it's unlikely Pantoja would find success in that area of the fight.While Pantoja's submission skills are probably superior to Dvalishvili's, the latter's wrestling and power should allow him to hold his own in any grappling situations.Quite honestly, there may not currently be a fighter who matches up well with Dvalishvili at flyweight or bantamweight.Remember, Dvalishvili has already faced and defeated most of the top-ranked guys in his division. As for Pantoja, he is coming off a successful title defense against Kai Asakura in the main event of UFC 310 at the T-Mobile Arena in Las Vegas in December 2024.He called out retired former flyweight kingpin Demetrious Johnson during his post-fight interview. Johnson quickly shot down the idea, saying he was happy staying retired and being a content creator on YouTube.Rising contenders like Tatsuro Taira, Asu Almabayev, Tagir Ulabekov, Charles Johnson, and Joshua Van could be next. However, perennial contenders and former champions like Brandon Royval, Brandon Moreno, Manel Kape, Kai Kara-France, and others would like another chance to dethrone Pantoja.What's Next for the UFC?There are no men's flyweight fights scheduled for the next UFC card. However, there are two noteworthy middleweight scraps on tap for the February 1 card in Saudi Arabia.Israel Adesanya vs. Nassourdine Imavov - Middleweight (185 lbs)Sharabutdin Magomedov vs. Michael Page - Middleweight (185 lbs)Sergei Pavlovich vs. Jairzinho Rozenstruik - Heavyweight (265 lbs)Said Nurmagomedov vs. Vinicius Oliveira - Bantamweight (135 lbs)Ikram Aliskerov vs. Andr Muniz - Middleweight (185 lbs)Muhammad Naimov vs. Kaan Ofli - Featherweight (145 lbs)Shamil Gaziev vs. Thomas Petersen - Heavyweight (265 lbs)Terrance McKinney vs. Damir Hadovi - Lightweight (155 lbs)Fares Ziam vs. Mike Davis - Lightweight (155 lbs)Jasmine Jasudavicius vs. Mayra Bueno Silva - Flyweight (125 lbs)Bogdan Grad vs. L.

Highly anticipated: As Bethesda and id Software start the final hype cycle before the launch of Doom: The Dark Ages on May 15, the official PC system requirements reveal that ray tracing, a once-optional feature that dramatically reduces frame rates, is increasingly becoming mandatory in major game releases. Notably, the game also requires an NVMe SSD. Doom: The Dark Ages, the upcoming prequel to id Software's 2016 revival of the classic FPS franchise, is now available for pre-order and is set to launch on May 15 on Steam, the Microsoft Store, Game Pass, Xbox series consoles, and PlayStation 5. Customers who pre-purchase the premium edition can begin playing on May 12.The system requirements confirm that the game requires a GPU capable of hardware-assisted ray tracing, even at the lowest graphics settings. Other examples of this trend include Star Wars Outlaws, Indiana Jones and the Great Circle, and the upcoming Assassin's Creed Shadows.Gameplay at 1080p and 60fps with low settings requires an Nvidia RTX 20 series, AMD Radeon RX 6000 series, or newer graphics card with at least 8 GB of VRAM. For higher graphics settings at 1440p, 32GB of RAM and 10GB of VRAM are recommended, while maxed-out 4K gameplay increases the VRAM requirement to 16GB.After showcasing the game at this week's Xbox Developer Direct, id Software also confirmed that Doom: The Dark Ages supports path tracing. Titles like Indiana Jones, Alan Wake 2, and Cyberpunk 2077 have used path tracing, also known as full ray tracing, to render extremely comprehensive lighting and shadows, albeit with a substantial performance cost. Further details on Doom's implementation of the feature are forthcoming.Click to enlargeAnother new mandate that might concern users with older PCs is 100GB of NVMe storage. High-end games now commonly require SSDs but typically also support SATA drives, and many will still launch on hard disk drives. // Related StoriesIn a roughly 10-minute demonstration (watch below), id showcased new weapons and other features from Doom: The Dark Ages. The chainsaw appears to have been replaced with a mace, flail, electrified gauntlet, and a throwable shield. New guns include a rail spike launcher, skull chipper, and a double-barreled plasma cannon. Additionally, the new entry boasts the largest and most densely populated levels in the franchise's history.Doom: The Dark Ages also gives players more granular control over the difficulty settings than prior titles. The options menu includes sliders for player damage, enemy damage, the parry window, overall game speed, and more.
