Phys.org / How boundary geometry helps embryonic cells organize themselves
One of the most striking biological transitions in nature happens early in development, when an embryo transforms from a simple ball of cells into a highly ordered structure with distinct tissue layers that later develop ...
Medical Xpress / Neural pathways reveal a push-pull system for coordinating goal-directed behavior in mice
Most of the tasks that humans complete daily entail carefully coordinating movements and tracking progress made toward a desired goal. Past studies have highlighted the role of the basal ganglia (BG), a set of interconnected ...
Phys.org / Portugal braces for high temperatures in new heat wave
Parts of Portugal, including the Lisbon region, will be placed on red alert after being relatively spared from Europe's worst heat wave, which set records in several countries.
Phys.org / A thermodynamic approach to gravity could explain cosmic acceleration without dark energy
Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general relativity. This framework describes gravity as the curvature of spacetime, the invisible four-dimensional ...
Tech Xplore / Surface oxidation, not water, drives Prussian blue battery failure
Like a delicate fabric that becomes damaged during drying, a promising next-generation battery material has faced an unexpected challenge: Removing water to improve performance can actually shorten battery life. Now, a Korean ...
Phys.org / How mating competition, age and sex shape immune systems in wild bats
A new study of wild bats reveals that an animal's immune system is shaped by more than its need to fight infections. Researchers from the University of Maryland have found that sex, age and competition for mates influence ...
Phys.org / The invasive fern that science misidentified for decades
Salvinia molesta can double its biomass in 36 hours. It spreads across ponds, lakes and slow-moving waterways in a smothering green mat, blocking sunlight, consuming oxygen and collapsing the ecosystems beneath it. Now present ...
Tech Xplore / New smart bicycle can tell when riders mean to turn—and when they may be falling
Two-wheeled vehicles with conventional stability-control systems must lean to change direction, making it difficult for rider-assistance systems to determine whether a rider is intentionally cornering or experiencing instability ...
Phys.org / 13,000 tons of space junk clutters Earth orbit. Here's how it could be cleaned up
Seventy years ago, Earth had only one satellite: the moon. Now it has more than 15,000—about 10,000 of which are owned by Elon Musk's SpaceX. The world's first trillionaire plans to launch 1 million more satellites, each ...
Tech Xplore / LiDAR approach could change factory inspections for tiny hard-to-reach parts
Researchers have developed a new LiDAR approach that makes it possible to image small objects with much greater precision and accuracy than conventional LiDAR. The method could be useful for acquiring noncontact measurements ...
Phys.org / 3D genome analysis of germ cell formation tracks 350 million years of vertebrate evolution
A research team led by the Universitat Autònoma de Barcelona (UAB) has revealed how the genome is reorganized in 3D during male germ cell formation in vertebrates, leading to important new insights into how biodiversity is ...
Tech Xplore / Meta shares surge on report of new AI cloud business
Shares of Meta Platforms jumped more than 6% on Wall Street on Wednesday after a report said the social media giant is preparing to launch a cloud computing business that would sell AI computing power to outside customers.
