The human dorsolateral prefrontal cortex is involved in cognitive control including attention selection, working memory, decision making and planning of actions. Changes in this brain region are suspected to play a role in schizophrenia, obsessive-compulsive disorder, depression and bipolar disorder, making it an important research target. Researchers from Forschungszentrum Jülich and Heinrich-Heine University Düsseldorf now provide detailed, three-dimensional maps of four new areas of the brain region.

In order to identify the borders between brain areas, the researchers statistically analysed the distribution of cells (the cytoarchitecture) in 10 post mortem human brains. After reconstructing the mapped areas in 3D, the researchers superimposed the maps of the 10 different brains and generated probability maps that reflect how much the localization and size of each area varies among individuals.

High inter-subject variability has been a major challenge for prior attempts to map this brain region leading to considerable discrepancies in pre-existing maps and inconclusive information making it very difficult to understand the specific involvement of individual brain areas in the different cognitive functions. The new probabilistic maps account for the variability between individuals and can be directly superimposed with datasets from functional studies in order to directly correlate structure and function of the areas.

Trains that run on hydrogen.

Re-sharing.

(CNN) — The future of environmentally friendly travel might just be here — and it’s Germany that’s leading the charge, with the first ever rail line to be entirely run on hydrogen-powered trains, starting from Wednesday.

The journey of half a million miles – the first flight of the Artemis Generation – is about to begin. The uncrewed Artemis I mission will jump-start humanity’s return to the Moon with the thunderous liftoff of NASA’s powerful new Space Launch System rocket and Orion spacecraft. This critical flight test will send Orion farther than any human-rated spacecraft has ever flown, putting new systems and processes to the test and lighting the way for the crew missions to come. Artemis I is ready for departure – and, together with our partners around the world, we are ready to return to the Moon, with our sights on Mars and beyond.

An exploration of the option of moving planets through gravitational migration and the idea of Earth getting ejected from the solar system and wander the galaxy as a rogue planet, perhaps to be captured by another star in the far future.

In a blood sample, the protein neurofilament is like the presence of rubble in a river — a sign of destruction upstream.

Seen most recently in sci-fi shows like ‘Westworld’ and ‘Severance,’ the sinister substance also exists in the real world—where it may control us all.

“If we could solve the problems of poverty by not pushing the button to launch men to the Moon tomorrow, then we would not push that button.”

NASA is prepping to send humans back to the Moon as soon as 2026. But Americans remain deeply divided on whether the agency would be better using its money on other endeavors.

When the MIT Lincoln Laboratory Supercomputing Center (LLSC) unveiled its TX-GAIA supercomputer in 2019, it provided the MIT community a powerful new resource for applying artificial intelligence to their research. Anyone at MIT can submit a job to the system, which churns through trillions of operations per second to train models for diverse applications, such as spotting tumors in medical images, discovering new drugs, or modeling climate effects. But with this great power comes the great responsibility of managing and operating it in a sustainable manner—and the team is looking for ways to improve.

“We have these powerful computational tools that let researchers build intricate models to solve problems, but they can essentially be used as black boxes. What gets lost in there is whether we are actually using the hardware as effectively as we can,” says Siddharth Samsi, a research scientist in the LLSC.

To gain insight into this challenge, the LLSC has been collecting detailed data on TX-GAIA usage over the past year. More than a million user jobs later, the team has released the dataset open source to the computing community.

A radical new idea for offshore wind turbines would replace tall unwieldy towers that had blades on top with lightweight, towerless machines whose blades resemble the loops of a whisk. Now new software can help optimize these unusual designs to help make them a reality, researchers say.

This new work comes as the U.S. government plans to boost offshore wind energy. In March, the White House announced a national goal to deploy 30 gigawatts of new offshore wind power by 2030. The federal government suggested this initiative could help power more than 10 million homes, support roughly 77,000 jobs, cut 78 million tonnes in carbon emissions, and spur US $12 billion in private investment per year. As part of this new plan, in June, the White House and eleven governors from along the East Coast launched a Federal-State Offshore Wind Implementation Partnership to further develop the offshore wind supply chain, including manufacturing facilities and port capabilities.

One reason offshore wind is attractive is the high demand for electricity on the coasts. People often live far away from where onshore wind is the strongest, and there is not enough space in cities for enough solar panels to power them, says Ryan Coe, a mechanical engineer in Sandia National Laboratories’ water-power group in Albuquerque.
