Tech Xplore / Sweat-sensitive jacket adjusts its thickness to keep you comfortable when it's cold
When we are out in cold weather, we wear warm clothes to stay comfortable. But there is a snag. Regular warm clothing can't adjust to changes in our body temperature. If we start to sweat, we get too hot and sticky, which ...
Phys.org / Robots team up to explore planetary lava caves
In the not-too-distant future, the search for signs of life on Mars and the moon could see the next generation of robots exploring a new frontier: subsurface lava tubes. These missions could also help us determine the best ...
Tech Xplore / Going places: Muscle-inspired mechanism powers tiny autonomous insect robots
Science frequently draws inspiration from the natural world. After all, nature has had billions of years to perfect its systems and processes. Taking their cue from mollusk catch muscles, researchers have developed a low-voltage, ...
Phys.org / The power of poop: How human waste can boost crop yields and cut greenhouse gas emissions
Human waste usually gets flushed away, but instead of going down the toilet, it can help the planet and solve global fertilizer shortages, according to a new study published in the journal Proceedings of the National Academy ...
Phys.org / Gene linked to skin's resistance to pressure sheds light on how animals adapted to life on land
One of the most significant moments in the evolutionary journey of life on this planet was the transition from water to land. This huge step required animals to adapt to new challenges, including supporting their body weight ...
Medical Xpress / Children's immune systems reveal new antibody targets for dengue vaccine development
In a new study, scientists have discovered more about how the body protects against dengue fever, one of the world's most common mosquito-borne illnesses, prompting hopes for more effective vaccines against the disease.
Phys.org / Connection with nature sees dramatic decline over the last two centuries
Over the past 220 years, the connection between people and nature has declined by more than 60%. That's the key finding of a study led by Miles Richardson, a professor of nature connectedness at the University of Derby in ...
Phys.org / Experimental device demonstrates how electron beams reconfigure plasma structure
In a scientific first, South Korean scientists have provided experimental proof of "multi-scale coupling" in plasma, where interactions between phenomena at the microscopic level and macroscopic level influence each other. ...
Phys.org / Eating the competition? New evidence suggests Neolithic farmers cannibalized enemies
Slicing, chopping and bite and cut marks on human remains from 5,700 years ago suggest that cannibalism may have been a common practice among our Neolithic ancestors.
Medical Xpress / Human eggs are protected from age-related genetic mutations, mtDNA study finds
As we age, the genes in our cells accumulate more mutations. This is one of the contributory factors to age-related diseases and the aging process. However, in a new study published in Science Advances, researchers have discovered ...
Tech Xplore / Meta's wristband breakthrough lets you use digital devices without touching them
Could Meta be on the verge of transforming how we interact with our digital devices? If the company's latest innovation takes off, we might soon be controlling our computers, cell phones and tablets with a simple flick of ...
Tech Xplore / WhoFi: New surveillance technology can track people by how they disrupt Wi-Fi signals
Hi-tech surveillance technologies are a double-edged sword. On the one hand, you want sophisticated devices to detect suspicious behavior and alert authorities. But on the other, there is the need to protect individual privacy. ...
Medical Xpress / Scientists use dental floss to deliver vaccines without needles
Flossing your teeth at least once a day is an essential part of any oral health routine. But it might also one day protect other parts of the body as scientists have created a novel, needle-free vaccine approach using a specialized ...
Phys.org / New study shows how sweat really forms
If you're currently experiencing a hot summer, the chances are the sweat is pouring off you, soaking your clothing. This clear, odorless substance is a vital component of a healthy bodily function that helps cool you down ...
Phys.org / DNA analysis reveals insights into Ötzi the Iceman's mountain neighbors
Ötzi the Iceman isn't the only ancient individual whose DNA is giving us insights into the past. So too are those of his neighbors. A new analysis of the genomes of 47 people who lived in the Austrian Tyrol between 6400 and ...
