A new study led by Colgate Assistant Professor of Physics and Astronomy Cosmin Ilie, working with Jillian Paulin ’23 of the University of Pennsylvania, Andreea Petric of the Space Telescope Science Institute, and Katherine Freese of the University of Texas at Austin, proposes a single idea that could address three…

Scientists turn tumor immune cells into cancer killers

Tumors in the human body contain immune cells called macrophages that are naturally capable of attacking cancer. However, tumors suppress these cells, preventing them from carrying out their cancer-fighting role. Researchers at KAIST have now developed a new therapeutic strategy that bypasses this suppression by turning immune cells already inside…

These nanoparticles could destroy disease proteins behind dementia and cancer

A newly released perspective article in Nature Nanotechnology describes an innovative nanoparticle-based approach designed to remove harmful proteins from the body. This advance could dramatically expand the ability to treat so-called “undruggable” proteins, opening new possibilities for diseases such as dementia and brain cancer. The work was led by Chair…

The hidden reason cancer immunotherapy often fails

Cancer immunotherapy has reshaped cancer treatment by training the body’s immune system to recognize and attack tumors. Drugs known as immune checkpoint inhibitors, which target the PD-1/PD-L1 pathway, have led to long-lasting responses in some patients and fueled optimism about durable cancer control. Yet for most people, these therapies do…

Why long COVID brain fog seems so much worse in the U.S.

An international study found that U.S. long COVID patients report far more brain fog and psychological symptoms than patients in lower-income countries. Researchers believe the gap is driven by culture and healthcare access, not biology — hinting that millions worldwide may be struggling unseen. A large study of more than…

The fat you can’t see could be shrinking your brain

How obesity affects the brain may depend on more than overall body weight. New research published on January 27 in Radiology, the flagship journal of the Radiological Society of North America (RSNA), suggests that the location of fat in the body plays a major role in brain health and cognitive…

Tea can improve your health and longevity, but how you drink it matters

A comprehensive review finds that tea, especially green tea, is strongly associated with a reduced risk of cardiovascular diseases (CVDs), obesity, diabetes, and several forms of cancer.

The discovery could lead to new treatments for osteoporosis and bone loss, particularly for people…

Scientists may have been wrong about what causes asthma

For many years, scientists believed they had a clear picture of what causes asthma. The condition has been linked to inflammation in the lungs that narrows the airways and makes breathing difficult. That inflammation was widely attributed to molecules known as “leukotrienes.” These chemicals are released by white blood cells…

Keto diet weight loss may come with a hidden cost

Researchers from University of Utah Health have published new findings in Science Advances that examine the long-term effects of the ketogenic diet. The results raise fresh questions about whether the diet is safe or effective for improving metabolic health over extended periods. Although the ketogenic diet was first developed as…

Scientists found a survival switch inside brain cells

Most cells in the human body can replace themselves after damage. Neurons, the cells that power the nervous system, usually cannot. Once injured, they rarely generate healthy replacements. Following events such as strokes, concussions, or neurodegenerative diseases, neurons and their axons are much more likely to deteriorate than to repair…

Scientists say quantum tech has reached its transistor moment

Quantum technology is rapidly moving beyond controlled laboratory experiments and into practical use. According to a new paper published in Science, the field has reached a critical phase that mirrors the early era of classical computing before the invention of the transistor reshaped modern technology. The paper was written by…

Strange white rocks on Mars hint at millions of years of rain

Small, pale rocks scattered across Mars’ reddish surface are offering fresh clues that parts of the planet may once have been far wetter than they are today. These light-colored spots stand out sharply against the surrounding terrain and suggest that some regions of Mars once hosted humid environments with frequent…

Scientists finally explain Earth’s strangest fossils

Creatures without hard shells or bones, such as jellyfish, almost never survive in the fossil record. Preservation becomes even more difficult in sandstone, a rock made of coarse grains that allow water to pass through easily and typically forms in turbulent environments shaped by waves and storms. These conditions usually…

A century-old Stonehenge mystery may finally be solved

New research from Curtin University offers the clearest scientific support so far that people, rather than glaciers, carried Stonehenge’s well known bluestones to the ancient monument.

A hidden genetic war is unfolding inside your DNA

In Lewis Carroll’s “Through the Looking-Glass,” Alice runs endlessly alongside the Red Queen but never moves ahead. “It takes all the running you can do to keep in the same place,” the Queen explains. That idea has long been used to describe evolutionary standoffs between species, such as hosts and…

A strange in-between state of matter is finally observed

When ice turns into water, the change happens almost instantly. As soon as the temperature reaches the melting point, the rigid structure of ice collapses into liquid water. This rapid switch from solid to liquid is typical for familiar three-dimensional materials. Extremely thin materials behave very differently. Instead of melting…

The early universe supercharged black hole growth

One of astronomy’s longest standing puzzles has been understanding how black holes grew so large in such a short span of cosmic time. Scientists have long known that supermassive black holes existed surprisingly early in the universe, but how they reached those enormous sizes remained unclear. Now, researchers at Ireland’s…
