A growing number of firms are turning fungi roots into clothing and building material.

Dedicated to ending the HIV epidemic — dr. moupali das, MD, MPH, executive director, HIV clinical research, gilead sciences.

Dr. Moupali Das, MD, MPH, is Executive Director, HIV Clinical Research, in the Virology Therapeutic Area, at Gilead Sciences (https://www.gilead.com/), where she leads the pre-exposure prophylaxis (PrEP) clinical drug development program, including evaluating the safety and efficacy of a long-acting, twice yearly, subcutaneous injection being studied for HIV prevention. Her responsibilities also include expanding the populations who may benefit from PrEP.

NASA has released a breathtaking time-lapse video captured from the International Space Station showing a recent aurora over Earth.

Scientists have made a freak discovery that’s potentially brought us closer to dinosaurs than we’ve ever been before.

Archaeologists uncovered one of the most well-preserved dinosaur fossils — so preserved that its very skin was still intact after all these years.

Talk about a good skincare routine, the discovery is now being hailed as a ‘one-in-a-billion’ find.

Sir Fred Hoyle was an English astronomer who formulated the theory of stellar nucleosynthesis. He also held controversial stances on other scientific matters — in particular his rejection of the “Big Bang” theory, a term coined by him on BBC radio, and his promotion of panspermia and the Steady-state theory of the universe.

Galaxies spotted by the James Webb Space Telescope seem far too massive to have formed so early on in the universe’s history, which could be a problem for our ideas of galaxy formation.

Experts consider glass nanoparticles kept inside extreme vacuum layers as potential platforms for examining the quantum world’s limits. However, a question in the field of quantum theory remains unanswered: at which size does an object start being described by quantum physics laws rather than classical physics laws?

Achieving Quantum-State Cooling in More Than One Direction Is Challenging

Computer models are an important tool for studying how the brain makes and stores memories and other types of complex information. But creating such models is a tricky business. Somehow, a symphony of signals—both biochemical and electrical—and a tangle of connections between neurons and other cell types creates the hardware for memories to take hold. Yet because neuroscientists don’t fully understand the underlying biology of the brain, encoding the process into a computer model in order to study it further has been a challenge.

Now, researchers at the Okinawa Institute of Science and Technology (OIST) have altered a commonly used computer model of memory called a Hopfield network in a way that improves performance by taking inspiration from biology. They found that not only does the new network better reflect how neurons and other cells wire up in the brain, it can also hold dramatically more memories.

The complexity added to the network is what makes it more realistic, says Thomas Burns, a Ph.D. student in the group of Professor Tomoki Fukai, who heads OIST’s Neural Coding and Brain Computing Unit. “Why would biology have all this complexity? Memory capacity might be a reason,” Mr. Burns says.
