When people in the United States start using appetite-suppressing medications such as Ozempic and Wegovy, the effects go far beyond weight loss. New research from Cornell University shows that these drugs are linked to noticeable drops in how much households spend on food, including groceries and meals eaten outside the…
After years of careful investigation, researchers working on the Micro Booster Neutrino Experiment (MicroBooNE) have determined that a long-hypothesized particle known as the sterile neutrino does not exist. This proposed particle had been widely discussed as a possible answer to unresolved problems in particle physics. Reporting their findings in the…
A large majority of U.S. adults are unfamiliar with cardiovascular-kidney-metabolic (CKM) syndrome, even though it affects nearly 90% of adults nationwide. CKM syndrome is a recently defined condition that brings together several major health problems, including heart disease, kidney disease, diabetes and obesity. According to a new survey from the…
After more than two years of fighting, many Palestinian children in Gaza are so physically depleted and emotionally distressed that they can no longer learn or play, according to a new report. The study warns that some children now believe they will be “killed for being Gazans.” Led by the…
How do embryonic stem cells become brain cells, and which genes make that transformation possible? A new study published on January 5 in Nature Neuroscience tackles this question using powerful gene editing tools. The research was led by Prof. Sagiv Shifman from The Institute of Life Sciences at The Hebrew…
Three newly identified compounds were found to strongly inhibit α-glucosidase, an enzyme that plays a central role in breaking down carbohydrates during digestion. Because this enzyme directly affects how quickly sugars enter the bloodstream, the discovery points to possible new functional food ingredients aimed at managing type 2 diabetes. Functional…
Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot fully explain this accelerating growth. Today’s standard picture of the universe is built on Einstein’s general theory of relativity and the standard model of particle physics. Within this framework, scientists…
Tumors in the human body contain immune cells called macrophages that are naturally capable of attacking cancer. However, the tumor environment suppresses these cells, preventing them from doing their job. Researchers at KAIST have now found a way to overcome this barrier by directly transforming immune cells already inside tumors…
This year’s flu season has been especially harsh, driven in part by the rapid spread of a new variant known as subclade K. As cases rise, a newly released study offers surprising insight into how influenza spreads and how people may better protect themselves from getting sick. To better understand…
For roughly 10,000 years, farming communities have improved their crops by saving seeds from plants with the best flavor, size, and toughness. This slow and careful process shaped nearly every fruit and vegetable found in grocery stores today. Most modern crops are the result of centuries or even millennia of…
Around 445 million years ago, Earth underwent a dramatic transformation that reshaped the future of life. In a remarkably short geological period, massive glaciers spread across the southern supercontinent Gondwana. As ice locked up water, vast shallow seas dried out, triggering an “icehouse climate” and radically altering ocean chemistry. The…
Astronomers at the University of California, Irvine have identified what appears to be the largest stream of super-heated gas ever observed in the universe, flowing out of a nearby galaxy known as VV 340a. The findings were reported in the journal Science. Using data from NASA’s James Webb Space Telescope,…
Scientists studying the Great Salt Lake have identified at least one species of nematode that is completely new to science, with evidence suggesting there may be a second. Researchers from the University of Utah recently published a paper describing the tiny roundworm and formally naming it in a way that…
A large international study has found that taking a daily fish oil supplement can sharply lower the risk of serious heart-related complications in people undergoing dialysis for kidney failure. The research was co-led in Australia by Monash Health and the School of Clinical Sciences at Monash University. The study, known…
Imaging tools have dramatically reshaped how scientists study the world, from charting faraway galaxies with radio telescope networks to revealing intricate structures inside living cells. Even with decades of progress, one major obstacle has remained. At optical wavelengths, it has been extremely difficult to capture images that are both highly…
Scientists studying tiny feldspar crystals inside Australia’s oldest volcanic rocks have uncovered new clues about the early history of Earth’s interior, the formation of continents, and the origins of the Moon. These minerals act like time capsules, preserving chemical signals from billions of years ago. The research was led by…
The human gut replaces its cells faster than any other tissue in the body. Every few days, fresh cells are produced by specialized stem cells that keep the intestinal lining healthy. Over time, however, these stem cells begin to accumulate epigenetic changes. These are chemical tags attached to DNA that…
Getting a full night of sleep may play a larger role in longevity than many people realize. New research from Oregon Health & Science University indicates that regularly getting too little sleep is linked to a shorter lifespan. The findings were recently published in the journal SLEEP Advances. Nationwide Data…
Alzheimer’s disease is the leading cause of dementia worldwide and remains one of the most serious challenges facing public health systems. New findings published in the journal Aging-US suggest that substances circulating in the blood may influence how quickly the disease advances. In experiments with mice, researchers found that blood…
Pancreatic ductal adenocarcinoma (PDAC) is both the most common and the deadliest type of pancreatic cancer. Most treatment strategies focus on blocking a frequently mutated cancer gene known as KRAS. While this approach can work in some cases, many PDAC tumors eventually evade these therapies. Researchers believe that combining treatments…
Astronomers analyzing fresh observations from NASA’s Hubble Space Telescope and several ground-based observatories have uncovered clear signs that a recently identified companion star is shaping the environment around Betelgeuse. The study, led by researchers at the Center for Astrophysics | Harvard & Smithsonian (CfA), shows that the companion star, called…
Astronomers working with the Hubble Space Telescope have identified an entirely new type of cosmic object. It is a cloud rich in gas and dominated by dark matter, yet it contains no stars. Scientists consider it a relic left behind from the earliest stages of galaxy formation. The object, known…
When bacteria in the mouth break down sugars from food, they release acids that gradually erode tooth enamel and cause cavities. These bacteria do not live alone. They form dense, plaque-like structures known as “dental biofilms” that cling to the surface of teeth. Within these biofilms, acid production can accelerate…
Age-related macular degeneration is the most common cause of vision loss and blindness among Americans age 65 and older. The disease worsens over time and primarily damages central vision, making it difficult to see faces, read text or focus on objects directly ahead. As the condition progresses, people may experience…
A large scale genetic analysis of more than 900,000 people has revealed that specific regions of DNA become increasingly unstable over time. These regions are made up of very short sequences that repeat again and again, and the study shows that they tend to grow longer as people age. Researchers…
People who consume higher amounts of food preservatives may face a greater risk of developing type 2 diabetes, according to a large new study. Preservatives are commonly added to processed foods and beverages to extend shelf life. The research was conducted by scientists from Inserm, INRAE, Sorbonne Paris Nord University,…
Scientists at the University of Southampton have developed a new strategy designed to strengthen how the immune system responds to cancer.
