It's not simply the accrual of excess fat that leads to disease. It's a change in the actual function and the capacity of the energy center within the cell to work properly. The circadian rhythm is the body's own internal 24-hour clock that regulates the sleep-wake cycle, hormone levels and metabolism, among other systems throughout the body.

Stellar activity such as solar storms and plasma turbulence from a star near a transmitting planet can broaden otherwise ultra-narrow signals. That spreads the power of any such transmission across more frequencies, the institute's scientists say, which makes it more difficult to detect using traditional narrowband searches.

The Spinosaurus is a sail-backed, crocodile-snouted dinosaur that Hollywood depicted as a giant terrestrial predator capable of taking down a T. rex in Jurassic Park 3. Then they changed their mind and made it a fully aquatic diver in Jurassic World Rebirth—a rendering that was more in line with the latest paleontological knowledge. But now, deep in the Sahara Desert, a team of researchers led by Paul C. Sereno discovered new Spinosaurus fossils suggesting both scientists and filmmakers might have got it all wrong again.

We think that in this early deuterostome, the median eye contained both ciliary and rhabdomeric cells. As a result, both cellular lineages were incorporated into a single, ancient, cyclopean eye, which later evolved into the vertebrate eyes.

Over two-thirds said they recommend their students consider careers outside academia. The majority had delayed hiring in their labs, and one-third had laid off workers. More than one in six said they have lost researchers to institutions in other countries since Trump took office. Sixty-eight percent said funding cuts and federal policy changes had moderately or significantly reduced the scope of their work.

We are firmly in the era of the satellite constellation—groups of dozens of similar satellites—and are currently entering the era of the mega constellation, wherein groups of thousands of satellites swarm the skies. The clusters of satellites started small, but, like a viral outbreak, they grew almost without us noticing—and now we're dealing with a pandemic.

The contemporary technology museum has emerged as a performative participant in the systems it seeks to document. The architecture of these institutions has become increasingly fluid and bold, often mirroring the velocity and complexity of the systems it houses. They operate as mediators between the human, the ecological, and the technological realms, transforming from encyclopedic warehouses into active educational engines.

Bay Area peregrine falcon numbers began plummeting after a massive, global outbreak of avian flu in 2020, the study documents, with only about a third of the nesting sites still in use as of 2025. The news, while dire, nevertheless helps scientists understand how the disease is impacting local populations, and what we can expect for their recovery.

According to the Free Energy Principle (FEP), developed by theoretical neuroscientist Karl Friston and colleagues, much of what the brain does can be understood as minimizing such mismatches—a technical form of 'surprise' defined as the improbability of sensory input given an internal model. The proposal brings perception, action, learning, and decision-making under a single framework.

The remote military range near the town of Tonopah is not primarily used for nuclear detonations, but it has long been linked to US nuclear weapons programs. The site is used to test how nuclear weapons would be delivered, including experiments where aircraft drop non-nuclear versions of bombs to study their performance.

The Natrium reactor, developed jointly by Bill Gates-backed TerraPower and GE Hitachi, is being built as part of the Department of Energy's Advanced Reactor Demonstration Program. It represents something genuinely new: a reactor designed from the ground up to complement renewable energy rather than compete with it.

As global competition in space accelerates, New York is mobilizing its premier research institutions through NYCST to address workforce shortages, close capability gaps and mature the critical technologies our nation needs. For decades, our state has been a home to innovative aerospace companies. Through NYCST, we are now aligning that heritage with our top-tier research institutions to ensure that industry can develop and scale up breakthrough technologies right here in New York.

The Starship rocket system splits in two after takeoff. The upper spacecraft would head to Earth orbit to serve as that depot, ready to carry nothing but fuel. The towering Super Heavy rocket booster, meanwhile, would return to the launch site so it can be reused.

The facility suffered a still unexplained mishap last November during the launch of a Soyuz capsule carrying two Russians and one American to the orbiting station. Officials said a component called a maintenance or service cabin failed to move out from under the blast of exhaust from the ascending rocket.

For over 15 years, the EFRC program has provided a transformational research environment that has brought together the strengths of our National Laboratories and universities to accelerate discovery, develop innovative tools, and train the next generation of the American energy science workforce. The EFRCs will continue to play a vital role in bridging disciplines and institutions, advancing foundational science and strengthening America's leadership to push forward scientific frontiers critical for new energy technologies.

The rods are the central element of a novel seismic-responsive structural system that is designed to help the building snap back to its original shape in the event of a major earthquake. Their trick is an embedded cluster of taut cables made from a highly flexible compound called a shape-memory alloy that's capable of bending under tension-like the lateral shaking in a California earthquake-and then straightening out.

If we told them to look at the face, they could usually manage it. But they were mostly looking at the hands. The Prakash children eventually learn to look at faces when spoken to - usually a few months after their surgeries. Their experiences reveal that seeing doesn't come naturally the moment a person is cured of blindness. Newly-sighted people must learn to see.
