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 ...
Phys.org / The rubber hand illusion works on octopuses too
Like humans, octopuses can fall for the rubber hand illusion and believe that a fake arm is theirs. This suggests they have a sense of their own body, just as we do.
Phys.org / Novel method of targeting disordered proteins could herald a new era for medicine
Scientists have discovered a new way to advance drug discovery and diagnostics by targeting a part of the proteome (the complete set of proteins in an organism) that was previously thought inaccessible to drug development, ...
Phys.org / How Google's Android earthquake detection system can save lives
If you're in an earthquake-prone area and own an Android phone, it could save your life. It may even have already done so. The Android Earthquake Alert (AEA) system, which began in the U.S. in 2020 and has since expanded ...
Tech Xplore / Tech giants warn window to monitor AI reasoning is closing, urge action
Artificial intelligence is advancing at a dizzying speed. Like many new technologies, it offers significant benefits but also poses safety risks. Recognizing the potential dangers, leading researchers from Google DeepMind, ...
Tech Xplore / New research reveals AI has a confidence problem
Large language models (LLMs) sometimes lose confidence when answering questions and abandon correct answers, according to a new study by researchers at Google DeepMind and University College London.
