Physicists have found a new way to switch superconductivity on and off in magic-angle graphene. The discovery could lead to ultrafast, energy-efficient superconducting transistors for 'neuromorphic' electronics that operate similarly to the rapid on/off firing of neurons in the human brain.
Engineers have developed a contact lens prototype that is specially designed to prevent contact lens-induced dry eye (CLIDE). The lens alleviates this condition by facilitating tear flow in response to normal eye blinking. This can relieve the discomfort, visual impairment, and risk of inflammation experienced by millions of CLIDE sufferers.
Researchers already knew the atoms in perovskites react favorably to light. Now they've seen precisely how the atoms move when the 2D materials are excited with light. Their study details the first direct measurement of structural dynamics under light-induced excitation in 2D perovskites.
Honey bee colony loss across the United States over the last five years is primarily related to the presence of parasitic mites, nearby pesticides, and extreme weather events as well as challenges with overwintering, according to a new study. The study took advantage of novel statistical methods and is among the first to concurrently consider a variety of potential honey bee stressors at a national scale.
Researchers got into the minds of muskies to learn what personality traits make the fish more likely to strike. In the process, they learned valuable lessons that could help conserve the important aquatic predators.
Researchers combine a hand-held scanner with a neural network based on terahertz spectroscopy that can predict burn healing with 93% accuracy. The research has the potential to significantly improve burn healing outcomes by guiding surgical treatment plans.
An innovative technique finds seminal fluid protein transferred from male to female fruit flies during mating changes the expression of genes related to the fly's circadian clock.
Stem cells have been modified to carry a therapy to treat companion animal patients with late-stage cancer, preserving good quality of life and extending their lives, potentially leading to better understanding of cancer treatments and their use in humans.
The precious metals, such as platinum, palladium and rhodium, in catalytic converters make the vehicle devices attractive to thieves, but researchers are working to reduce the amount of precious metals needed in them -- down to single atoms -- while still maximizing their effectiveness. In recent studies researchers showed that they could, respectively, use atomic platinum to control pollutants and operate the system at lower temperatures, which is crucial to removing harmful chemicals when a vehicle first starts.
If you've ever watched an ant searching for food, you probably assumed that they were just covering ground in a random fashion. But a study now finds that at least one species of rock ant doesn't walk randomly at all. Instead, their search combines systematic meandering with random walks interspersed.
New research challenges the prevailing hypothesis for how donor stem cell grafts cause graft-versus-host disease, or GVHD, and offers an alternative model that could guide development of novel therapies.
Researchers have combined low-power chip design, machine learning algorithms, and soft implantable electrodes to produce a neural interface that can identify and suppress symptoms of various neurological disorders.
Spinal cord stimulation uses low levels of electricity to relieve pain. A study is the first to measure this treatment's effects on patients by gauging improvement in insomnia after spinal cord stimulation. Results showed a 30 percent or more improvement of both nighttime and daytime components of insomnia in 39.1 percent of study participants and a 30 percent or more improvement of daytime sleepiness in 28.1 percent of participants. Findings correlated with improvement in disability and depression and revealed associations with sleep and both pain and depression. Results will help clinicians gain a better understanding of the type of patient most likely to benefit from this treatment.
Cooking a delicious risotto and making plastics are actually very similar processes. In both, ingredients come together and are heated to create a product, but current recipes for synthesizing bioplastics often fall flat, producing flimsy materials. So, taking a hint from chefs, researchers now report on a way to 'season' biodegradable plastics to make them stronger. It just takes a 'pinch' of cream of tartar (tartaric acid) or citric acid.
Whether you call them comfort foods, highly processed foods, junk foods, empty calories or just some of Americans' favorite foods and drinks, about 13% of people aged 50 to 80 have an unhealthy relationship with them, according to a new poll.
A new study has for the first time predicted which invasive species could pose a future threat to the UK's ecologically unique Overseas Territories.
Having levels of potassium that are too high or too low can be fatal. A new mathematical model sheds light on the often mysterious ways the body regulates this important electrolyte.
The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?
Can something as simple as a cup of coffee with milk have an anti-inflammatory effect in humans? Apparently so, according to a new study. A combination of proteins and antioxidants doubles the anti-inflammatory properties in immune cells. The researchers hope to be able to study the health effects on humans.
Despite birth control existing for decades, almost none of the options specifically target sperm cells. Researchers are now developing approaches that target testosterone or otherwise interrupt the sperm's ability to fertilize an egg, yet these may not work for everyone. But now, researchers have identified a new candidate molecule that could become an effective non-hormonal contraceptive for many people who produce sperm.
