Traumatic brain injury (TBI) remains one of the most pressing public health challenges, leaving millions with lasting disabilities each year. When the brain suffers a sudden impact, from a fall, vehicle accident, or sports collision, it triggers inflammation, oxidative stress,
"Time flies," "time waits for no one," "as time goes on": The way we speak about time tends to strongly imply that the passage of time is some sort of real process that happens out there in the world. We inhabit the present moment and move through time, even as events come and
Under the influence of global warming, the Arctic is transitioning from a state dominated by multi-year thick ice to a "New Arctic" characterized predominantly by first-year thin ice. This younger ice is more fragile and prone to melting, which not only exacerbates the

A systematic review of academic research in the International Journal of Web Based Communities has looked at the relationship between the leading online video content sites and its recommendation system and how this might affect the circulation of polarized or misleading
Gut microbes are essential partners that help digest food, produce vitamins and train the immune system. They can also pass on behavioral traits to their host's offspring, at least in mice. Scientists at the Max Planck Institute for Biology Tübingen have discovered that the
When an intense laser pulse hits a stationary electron, it performs a trembling motion at the frequency of the light field. However, this motion dies down after the pulse, and the electron comes to rest again at its original location. If, however, the light field changes its
Artificial intelligence (AI) is no longer a mere technological tool. It has already evolved into a new ideology—a system of values and beliefs that is shaping how society understands progress, sustainability, and even humanity itself.
A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like dancers following a beat.
By fusing enzyme fragments to antibodies, researchers from the Institute of Science Tokyo, in Japan, developed an innovative enzyme switch called "Switchbody," which is activated when bound to its target antigen. Switchbody is based on a trap-and-release of enzyme fragment that
Agriculture, wastewater, dams, the runoff of fine sediments from croplands and, last but not least, climate change with its rising temperatures are changing the quality and structure of freshwater ecosystems, especially rivers. However, until now there has been no clear picture

Mild wounds healed faster if people took a spray containing the "love hormone" oxytocin and set aside time to praise their partner – but they cleared up even quicker if these individuals were also intimate with their other half
It is difficult to ignore the intertwined nature of the commercialized UK higher education model and its reliance on international student fee income. One in four students enrolled in higher education courses in the UK in 2023-24 is of non-UK origin. This is an increase from
If you've been following recent debates about health, you've been hearing a lot about vaccines, diet, measles, Medicaid cuts and health insurance costs—but much less about one of the greatest threats to global public health: climate change.
What do you picture when you think about climate change? For many of us, it is the same set of dramatic images: melting glaciers, sinking landforms, rising seas or extreme weather.
In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called "Is the end in sight for theoretical physics?"
Mount Kilimanjaro in Tanzania is sold to the world as frozen romance and pure nature. But the real story today is at its feet, not its peak.
