Phys.org / Recyclable glue bonds underwater in seconds and holds for years
Most glues need a dry surface to stick properly. Bonding materials underwater is challenging because water forms a thin film on any surface, so instead of an adhesive touching a material directly, it touches a layer of water, ...
Medical Xpress / An origami-inspired implant could monitor health from beneath the skin
The skin is the body's largest organ. It is a protective shield that keeps harmful pathogens out and vital fluids inside. These very properties make it a tough engineering challenge to design wearable health sensors because ...
Phys.org / Historical DNA reveals largetooth sawfish have lost much of their genetic diversity
The genetic diversity of the largetooth sawfish (Pristis pristis), a critically endangered ray, has plummeted over the past century and a half, according to a study published in the Proceedings of the Royal Society B: Biological ...
Phys.org / AI cyclone forecasts could add 30 hours of warning time
Tropical cyclones are among the most destructive natural forces on the planet, but predicting where they will go and how strong they will become is beset by challenges. Current methods are often good at tracking storm paths ...
Phys.org / Sixteen AI-designed viruses offer a new route against drug-resistant bacteria
In a world first, scientists led by a team from Stanford University have created 16 viable viruses that do not exist in nature and were designed by AI. Their experiment, which is published in Science, could help in the fight ...
Phys.org / Swarms of tiny robots remove microplastics from soil and water
Microplastics, which are plastic particles under 5 millimeters, are a major and growing threat in both soil and water. They damage soil fertility, disrupt nutrient cycling, harm aquatic and terrestrial life, and can move ...
Phys.org / Tiny floating magnet detects ultrafaint magnetic fields at room temperature
Measuring faint magnetic fields is useful in a number of areas, including mapping brain activity, monitoring hearts and probing fundamental physics. Typically, picking up such weak signals requires expensive or bulky equipment, ...
Phys.org / Boron layers could set a superconductivity record, theoretical study predicts
Scientists in China predict that stacking two microscopic layers of boron could set a new record for superconductivity. Superconductors are materials that conduct electricity with zero resistance. Traditional types need temperatures ...
Phys.org / Two-qubit entangling gate flags its own errors as detectable photon losses
Quantum errors are a normal part of quantum computing because fragile physical qubits (the tiny components storing data) can easily break down because of environmental noise, like heat, stray signals or microscopic vibrations. ...
Medical Xpress / Birth order may influence your disease risk later in life, study finds
Whether you are first-born or second-born may be associated with your risk of developing certain diseases, according to a new study published in Nature Health.
Phys.org / A temperature dial for more realistic quantum simulations
Scientists from Rice University in the U.S. have developed a way to precisely tune the temperature inside a trapped-ion simulator. The breakthrough means they will be able to run quantum simulations at precise temperatures ...
Phys.org / Why some people are mosquito magnets while others get away unbitten
Some mosquitoes really are picky eaters. They will not just stick their proboscis into any old human. We know this anecdotally, with some people claiming they are always bitten while others are completely ignored, though ...
Phys.org / New quantum encryption method prevents ciphertext from being cloned
Digital security currently relies on difficult equations to protect data. For example, when you use a credit card online, the information is locked inside a math problem that would take a modern computer thousands of years ...
Tech Xplore / Prototype glasses can turn infrared into color vision
The human eye, as good as it is, misses out on so much of the world because it is limited in what it can perceive. It can't see X-rays, ultraviolet rays or infrared light. While X-ray goggles are still the stuff of science ...
Phys.org / How simple amber lights could make nights safer for insects
Approximately 40% of insect species worldwide are thought to be in decline and under threat of extinction. Among the key causes are habitat loss, pollution and climate change. Another threat is artificial light from sources ...
