Billions of years ago, Mars was hypothesized to have been a habitable world with flowing liquid water and the potential for life. But directly studying its ancient past is currently limited to orbiters and rovers, as scientists have yet to obtain direct samples from Mars. However, meteorites have been found on Earth to have potentially […] The post Dry Martian Meteorite Reveals Early Water in Mar…

Scientists are turning to an unusual source of inspiration in the fight against financial crime: swarms of ants, bees and birds. Researchers led by Charles Darwin University (CDU) have proposed a new artificial intelligence system that uses ideas from the collective behavior of social animals to identify suspicious money flows on blockchain networks. The approach […] The post Scientists Turn to A…

As tornadoes, hurricanes and other extreme weather events threaten communities, researchers are exploring whether 3D-printed concrete could provide stronger and more affordable storm shelters for people who need them most. Reese Greenlee, an assistant professor of architecture at Kansas State University, is studying how 3D printing could be used to build storm shelters for manufactured […] The po…

Quantum technology could one day make communications more secure and sensors far more sensitive. But there is a major obstacle: many quantum systems only work at extremely low temperatures, requiring large, expensive cooling equipment. MIT researchers have now developed a small magnetic device that can produce strongly linked microwave signals at room temperature. The advance […] The post Scienti…

People using prosthetic limbs may one day be able to feel pressure, temperature and even differences between surfaces thanks to a new type of electronic skin developed by researchers at Washington State University. The technology, described in Cell Reports Physical Science, uses a network of tiny sensors designed to fit closely around prosthetic limbs. According […] The post New Electronic Skin C…

A new type of 3D printing could dramatically speed up the way tiny, complex objects are made. Instead of slowly building an object one layer at a time, researchers have developed a technique that can create an entire 3D structure—including hollow spaces inside it—with a single burst of laser light. Scientists at the University of […] The post New 3D Printing Technology Creates Complex Objects in …

Being young does not necessarily mean the heart and blood vessels are free of health risks. New research involving adults with an average age of just 23 found that most participants had at least one sign of cardiovascular, kidney or metabolic risk. Those with more advanced problems were also more likely to show early injury […] The post 80% of Young Adults Already Show Early Heart, Kidney and Met…

A daily soda, sports drink or glass of sugary punch may carry a health risk that researchers have only recently begun to explore. A long-running U.S. study found that people who regularly drank sugar-sweetened beverages were more likely to develop stomach cancer than those who almost never drank them. Surprisingly, the same pattern was not […] The post Sugary Drinks May Carry a Hidden Cancer Risk…

Improving heart health does not always require dramatic lifestyle changes. According to a new Penn State study, one simple habit may make a small but meaningful difference for adults with obesity: eating one avocado every day. The findings, published in the Journal of Clinical Lipidology, suggest that this everyday fruit may help lower one important […] The post Can a Daily Avocado Improve Heart …

Scientists have found that a natural substance made by the body after eating certain foods may help the heart relax and work better in a difficult-to-treat form of heart failure. In experimental models, the compound improved some measures of heart function by as much as 80%. The substance is called urolithin A. The body can […] The post Natural Compound May Help a Stiff Heart Relax appeared first…

The temperature on the thermostat may not be the only thing determining whether a room feels too hot or too cold. A new study suggests that subtle changes in ordinary white lighting can also influence how warm or cool people feel. Researchers led by scientists at Penn State found that changing the amount of red […] The post A Surprising Way to Make Rooms Feel Cooler Without Lowering the Thermosta…

Asking for help with an addiction can already be difficult. A new study suggests that people with opioid addiction may face an additional obstacle: negative attitudes among some mental health workers and first responders. Researchers at the University of Georgia surveyed people across the southern United States and found unexpectedly high levels of stigma among […] The post People With Opioid Add…

A medicine cannot repair an arthritic joint if it disappears before it has enough time to work. That simple problem has limited efforts to develop better injections for osteoarthritis, especially for experimental drugs that dissolve poorly in joint fluid. A technology from the University at Buffalo aims to solve this by turning an injection into […] The post New Gel May Treat Arthritis More Effec…

Many people think healthy ageing depends mainly on eating well and exercising. While those habits are important, researchers now believe that something much simpler may also make a difference. Following the same daily routine may help reduce pain and improve mental health, according to new research from the University of Missouri. The study focused on […] The post Sticking to the Same Daily Sched…

Ultra-processed foods have become one of the biggest topics in nutrition. Many people now check food labels mainly to see how processed a product is. A new study suggests there may be a better question to ask: How nutritious is the food? Scientists from the Harvard T.H. Chan School of Public Health analysed data collected […] The post The Truth About Harmful Effects of Processed Foods appeared fi…

Why does exercise seem almost like medicine for aging muscles? Scientists may now have a much clearer answer. A new study from Duke-NUS Medical School has identified a gene that appears to control whether older muscles can repair themselves properly. The discovery could eventually lead to treatments that help preserve muscle strength as people age. […] The post The Hidden Reason Exercise Keeps Ol…

Finding effective treatments for progressive supranuclear palsy has been one of the biggest challenges in brain disease research. A fresh analysis by scientists at Tel Aviv University now suggests that one experimental drug may have been overlooked because researchers originally analysed men and women together instead of separately. The study appeared in Molecular Psychiatry. Progressive […] The …

Air travel may one day get a little greener thanks to an unlikely fuel source: coconuts. Researchers at Osaka Metropolitan University have developed a biofuel made from coconut oil that can be blended with conventional jet fuel and used in existing turbine engines without significantly reducing engine efficiency. The fuel may also help lower some […] The post Scientists Develop Coconut Jet Fuel T…

Anyone who has struggled with an arcade claw machine knows that controlling a mechanical arm is not as easy as it looks. Excavator operators face a much harder version of the same problem. They must coordinate several joystick movements to control the machine’s boom, arm, bucket and cab at the same time. Learning those controls […] The post MIT’s New Excavator Controller Could Help Beginners Dig …

A gigantic line of cliffs may once have stretched for thousands of kilometers across ancient North America, helping erase more than a billion years of geological history from rocks now exposed in the Grand Canyon. Scientists led by the University of Southampton in the UK believe this enormous landscape formed about 800 million years ago, […] The post Lost Mega-Cliff May Explain the Grand Canyon’s…
