The MeerKAT radio telescope, composed of 64 dish antennas located in South Africa’s Northern Cape province, was built to study cosmic hydrogen, galaxy formation and evolution, and transient radio sources. As the precursor to the planned Square Kilometer Array telescope, its scientific goal is to map the radio sky in preparation for more ambitious campaigns […] The post Astronomers Hear the Faint …

A cooling cup of coffee seems to follow a simple rule: heat moves from warmer areas to cooler ones. This familiar process has been described successfully for about two centuries. But at the tiny scales found inside modern computer chips, heat can behave in much stranger ways. A new theoretical framework developed by Auburn University […] The post Heat Can “Remember” Its Past, New Theory Reveals a…

Engineers have developed a faster way to manufacture carbon-carbon composites, exceptionally strong materials used to protect spacecraft and high-speed vehicles from extreme heat. The new method could reduce production time from several months to only a few days. The technique was created by engineers at the Johns Hopkins Applied Physics Laboratory in Maryland. Called FAST […] The post Engineers …

All known life on Earth stores genetic information using the same four-letter DNA alphabet. Researchers have now shown that one of biology’s most important enzymes can accurately read an artificial DNA system containing eight letters. The discovery suggests that the natural machinery inside living cells may be able to work with a much larger genetic […] The post Natural Enzyme Successfully Reads …

The clouds of Venus may seem like one of the last places where the building blocks of life could survive. They consist mostly of concentrated sulfuric acid, a highly corrosive substance capable of dissolving metals and destroying many biological molecules found on Earth. However, a new study suggests that some important molecules may be surprisingly […] The post Building Blocks of Life Can Fold a…

Fat does not only collect under the skin or around the waist. Small amounts of fat can also build up inside muscle cells, and too much of it may interfere with the way muscles use energy. This type of fat buildup becomes more common with aging, physical inactivity and diets that are high in fat. […] The post Blueberry Compound May Help Muscles Burn Fat appeared first on Knowridge Science Report .

Surviving prostate cancer is only part of the long-term health picture. Many men whose cancer has not spread can live for years or decades, and during that time illnesses such as heart disease and other cancers may become as important as the original diagnosis. Researchers are increasingly asking whether everyday habits after cancer treatment can […] The post A Simple Food Swap May Help Prostate …

A man with pancreatic cancer that had spread through his body experienced an exceptionally rare outcome after receiving an experimental four-drug treatment. After responding strongly enough to undergo surgery, doctors examined the removed tissue and found no living cancer cells. More than three years after beginning treatment, he remained cancer-free, including more than two years […] The post On…

Metformin has been used for decades to help people with type 2 diabetes control their blood sugar. Now scientists are asking a much bigger question: could this common, inexpensive medicine also help the body age more slowly? A recent scientific review brought together decades of research on metformin, ranging from experiments in cells and animals […] The post Could Diabetes Drug Metformin Help Yo…

A long day spent sitting may affect health differently depending on how that sitting time is spread out. New research suggests that remaining sedentary for long, uninterrupted periods could be more concerning than the same amount of sitting broken up by regular movement. The study was led by Frederick Ho of the University of Glasgow […] The post Longer Sitting Time Linked to Higher Cancer Death R…

Inflammation is one of the body’s most important defense systems. When an infection or injury occurs, the immune system sends cells and chemical signals to the affected area to help protect the body and begin repairs. Problems can develop when this response does not switch off properly. Long-lasting inflammation has been linked to many illnesses, […] The post Study Finds a Key Switch Behind Harmf…

Dementia and age-related memory problems are becoming an increasingly important health challenge as populations around the world grow older. Although people cannot change some risk factors, such as age or inherited genes, research suggests that everyday habits may influence how well the brain ages. Diet is one area receiving growing attention. Scientists have already studied […] The post Japanese…

Younger brains are often thought to recover from injury better than older brains. Their ability to change and form new connections can help them adapt after damage, but new research suggests that this flexibility may also create an unexpected risk. Scientists at Texas A&M University found that age may change the way the brain responds […] The post Young Brains May Face a Hidden Risk After Injury …

By the time Alzheimer’s disease causes noticeable memory loss, changes inside the brain may have been developing for many years. A new study suggests that some of those changes could be visible much earlier than scientists once believed. A research team at the University of Oslo tracked healthy older adults over many years and discovered […] The post Alzheimer’s May Leave a much Earlier Mark on t…

Alcohol is often discussed in connection with liver damage, accidents and addiction. But a large U.S. study suggests its impact on cancer is also substantial, with the number of cancer deaths attributed to alcohol rising dramatically since 1990. The research was led by scientists at Sylvester Comprehensive Cancer Center, part of the University of Miami […] The post Alcohol’s Hidden Cancer Toll Is…

The earliest light in the universe, known as the cosmic microwave background, has been traveling since the dawn of the universe over 14 billion years ago. A group of scientists from 30 institutions has released the sharpest and clearest map ever made of the mass in the universe, created by measuring how this ancient light […] The post South Pole Telescope Releases Clearest Map Ever of Matter in t…

An extinct North American cat commonly called the American cheetah was not a true cheetah at all. New genetic evidence shows that it was a close relative of the modern puma—and some populations survived in the Arctic by eating fish. The study, led by researchers at the University of California, Santa Cruz, examined ancient DNA […] The post The “American Cheetah” Was Actually a Fish-Eating Arctic …

Bladder cancer can be difficult to investigate because one of its most common warning signs, blood in the urine, has many possible causes. Most people who are urgently referred for testing do not turn out to have cancer, but doctors still need to rule out the disease quickly and safely. New research led by the […] The post Simple Urine Test Finds Most Bladder Cancers appeared first on Knowridge S…

Changes in the voice may offer an overlooked clue about future problems with thinking and memory. A large study from Drexel University found that people diagnosed with a voice disorder, but not hearing loss, had a 58% higher risk of later cognitive impairment or dementia than similar people without either problem. Voice disorders can affect […] The post Voice Changes May Be an Early Sign of Demen…

Living creatures constantly adjust their behavior according to signals from inside their bodies. Hunger makes food more important, thirst creates a need for water, and cold encourages an animal to seek warmth. These internal needs continue to provide useful guidance even when the outside environment changes. Most artificial intelligence systems work differently. They usually pursue […] The post S…
