Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have made a surprising discovery that could help explain our risk for developing chronic diseases or cancers as we get older, and how our food decomposes over time.
Research on novel nanoelectronics devices led by the University of Southampton enabled brain neurons and artificial neurons to communicate with each other.
This study has for the first time shown how three key emerging technologies can work together: brain-computer interfaces, artificial neural networks and advanced memory technologies (also known as memristors).
The discovery opens the door to further significant developments in neural and artificial intelligence research.
Although quitting smoking during the 1st trimester of pregnancy reduces the risk of low birth weight, it isn't enough to protect the unborn child from being born shorter and with smaller brain size, a new study from the University of Eastern Finland shows. The study looked at 1.4 million mother-child pairs in Finland, analysing the effect of maternal smoking on newborns' body size and body proportions when the mother had smoked only during the 1st trimester as opposed to continued smoking. The findings were published in BMJ Open yesterday.
According to a preliminary assessment from the German Federal Institute for Risk Assessment (BfR), the prohibited use of synthetic cannabinoids in e-liquids can be assumed with high likelihood
as reason for the observed symptoms. According to media reports, the patients admitted to have consumed cannabidiol (CBD). CBD is a weakly psychoactive cannabinoid. Already a year ago, the use of
CBD liquids manipulated with psychoactive cannabinoids has
been reported on from the USA. The users suffered from neurological symptoms as the youths in Bremerhaven.
(PHILADELPHIA) - N-acetylcysteine (NAC) is a naturally occurring molecule that replenishes antioxidants and shows improved brain metabolism and self-reported improvements in cognitive function in patients with multiple sclerosis, according to a study published in the journal, Frontiers in Neurology.
Public health agencies worldwide have identified antibiotic resistance of disease-causing bacteria as one of humanity's most critical challenges. However, scientists haven't discovered a new class of antibiotics in more than 30 years. Now, researchers reporting in ACS Infectious Diseases have uncovered the hidden antibiotic potential of a non-psychoactive cannabis compound called cannabigerol (CBG), which helped control methicillin-resistant Staphylococcus aureus (MRSA) infections in mice.
Hershey, Pa. -- On February 6, the U.S. Food and Drug Administration (FDA) began to enforce a previously-issued policy on unauthorized flavored cartridge-based e-cigarette products with the goal of addressing the current epidemic of youth use of e-cigarettes. A new study by researchers at Penn State finds that adults enjoy sweet e-cigarette flavors just as much as teens, suggesting that the policy may have consequences for adults too.
Many satellites are in space to take photos. But a vibrating satellite, like a camera in shaky hands, can't get a sharp image. Pointing it at a precise location to take a photo or perform another task, is another important function that requires accuracy. Vedant, an aerospace engineering doctoral student at the University of Illinois at Urbana-Champaign was working on a way to eliminate vibrations on a satellite when he discovered his invention could also rotate the satellite.
February 26, 2020 - Rates of diagnosed attention deficit-hyperactivity disorder (ADHD) in veterans receiving care in the VA health system more than doubled during the past decade, reports a study in the March issue of Medical Care.
Since incidents at Three Mile Island, Chernobyl, and Fukushima, many countries have switched from nuclear power to electricity production fired by fossil fuels, despite the environmental consequences of burning fuels such as coal. A new study used data from the United States to analyze the costs and benefits of electricity production from coal-fired versus nuclear sources. The study's authors conclude that policymakers should look at nuclear power as a low-carbon electricity source, but that utilities will need to have incentives to do so.
Some molecules, including most of the ones in living organisms, have shapes that can exist in two different mirror-image versions. The right- and left-handed versions can sometimes have different properties, such that only one of them carries out the molecule's functions. Now, a team of physicists has found that a similarly asymmetrical pattern can be induced and measured at will in certain exotic materials, using a special kind of light beam to stimulate the material.
February 26, 2020 - For women receiving breast implants during reconstructive or cosmetic breast surgery, scarring around the implant - called capsular contracture - is a common, costly, and painful complication.
If someone asked you right now how stressed you are, what would you say? A little? A lot? You do not know?
Policymakers will need to step up to the challenges caused by significant shifts in fish species distributions caused by climate change.
Tropical countries stand to lose the most fish species due to climate change, with few if any stocks replacing them, according to a study published in the journal Nature Sustainability. This could pose a serious governance challenge that warrants careful policy-making, the researchers say.
As sea temperatures rise, fish species migrate towards cooler waters to maintain their preferred thermal environments.
A team of scientists at the Hong Kong University of Science and Technology (HKUST) has recently made an important discovery in identifying a set of potential vaccine targets for the SARS-CoV-2 coronavirus, providing crucial leads for guiding experimental efforts towards the vaccine development against the novel pneumonia (COVID-19) caused by the virus.
