Scientists found that certain molecules made by gut bacteria travel to the liver and help control how the body uses energy. These molecules change depending on diet, genetics, and shifts in the microbiome. Some even improved insulin response in liver cells when tested in the
An international team of scientists have identified nine new species of butterflies using a combination of geographical, morphological and molecular analysis.
The cells of all animals—including humans—are characterized by their ability to adhere particularly well to surfaces in their environment. This mechanically stable adhesion enables the development of complex tissues and organs and is made possible by certain cell surface
A series of century-scale droughts may have quietly reshaped one of the world’s earliest urban civilizations. New climate reconstructions show that the Indus Valley Civilization endured repeated long dry periods that gradually pushed its people toward the Indus River as
Liquids and solutions are complex environments—think, for example, of sugar dissolving in water, where each sugar molecule becomes surrounded by a restless crowd of water molecules. Inside living cells, the picture is even more complex: tiny liquid droplets carry proteins or
Male bonobos have an impressive ability to detect when females are most fertile, even though the usual visual cues are unreliable. Researchers tracking wild bonobos in the Congo discovered that males skillfully interpret a mix of swelling timing and a female’s reproductive
Senescent “zombie” cells are linked to aging and multiple diseases, but spotting them in living tissue has been notoriously difficult. Researchers at Mayo Clinic have now taken an inventive leap by using aptamers—tiny, shape-shifting DNA molecules—to selectively tag these
For much of my career, I have been fascinated by the ways in which materials behave when we reduce their dimensions to the nanoscale. Over and over, I've learned that when we shrink a material down to just a few nanometers in thickness, the familiar textbook rules of physics
In a new study published in Nature Physics, researchers have achieved the first experimental observation of a fragile-to-strong transition in deeply supercooled water, resolving a scientific puzzle that has persisted for nearly three decades.
Scientists have found a way to turn carbon dioxide and methane, the two most notorious greenhouse gases, into useful chemicals without any expensive catalysts, using only light.
Forskolin, a plant-derived compound, shows surprising potential against one of the most aggressive forms of leukemia. Researchers discovered that it not only stops cancer cells from growing but also makes them far more vulnerable to chemotherapy by preventing them from pumping
Researchers used a deep learning AI model to uncover the first imaging-based biomarker of chronic stress by measuring adrenal gland volume on routine CT scans. This new metric, the Adrenal Volume Index, correlates strongly with cortisol levels, allostatic load, perceived
Imagine wearable health sensors, smart packaging, flexible displays, or disposable IoT controllers all manufactured like printed newspapers. The same technology could underpin communication circuits, sensors, and signal-processing components made entirely from
Astronomers tracked a decade of dramatic changes in P13, a neutron star undergoing supercritical accretion. Its X-ray luminosity rose and fell by factors of hundreds while its rotation rate accelerated. These synchronized shifts suggest the accretion structure itself evolved
Webb’s latest observations reveal a hellish world cloaked in an unexpected atmosphere: TOI-561 b, an ultra-hot rocky planet racing around its star in under 11 hours. Despite being blasted by intense radiation that should strip it bare, the planet appears to host a thick layer
The U.S.’s and Denmark’s health systems are starkly different, so it makes sense that their vaccination schedules would differ, too
Researchers at the University of Warsaw have unveiled a breakthrough method for detecting and precisely calibrating terahertz frequency combs using a quantum antenna made from Rydberg atoms. By combining atomic electrometry with a powerful terahertz-to-light conversion
MOCHI uses microscopic, air-filled channels to stop heat in its tracks while remaining nearly crystal clear. If scaled up, it could transform windows into powerful energy savers and solar harvesters.
Online violence is spilling offline: 4 in 10 women journalists, activists, influencers, and defenders of human rights report experiencing offline attacks connected to digital abuse.
Imagine sipping a latte while stroking an owl or watching an otter play at your feet. This is the promise of exotic animal cafes, a trend that blends coffee culture with wildlife encounters. But behind the Instagram-worthy photos lies a troubling reality—the welfare of the
Farmers have increasingly sown a single type of grass in their fields over the past 100 years, and then added chemical fertilizer to increase their harvest. But new research suggests that there are alternatives that are cheaper and can increase the potential of these grasslands
Loons are on the mend in Maine, filling more of the state's lakes and ponds with their haunting calls, although conservationists say the birds aren't out of the woods yet.
If mistletoe's status as a nutrient-stealing freeloader has been cooling your holiday ardor, new research led by an Oregon State University scientist may help relight the fire.
