Oxidative stress – characterized by elevated levels of unstable molecules called reactive oxygen species– is associated with neurodegeneration and cardiovascular disease. However, until recently it has not been possible to demonstrate a causal relationship between oxidative stress and disease states. A new study used “chemogenetics” to activate a recombinant yeast protein expressed in mouse tissues to manipulate levels of oxidative stress in living mice. Researchers from Brigham and Women’s Hospital, Harvard Medical School, and the Novartis ...

SAN ANTONIO —Wednesday,  June 14, 2023 —The search for extraterrestrial life in our solar system just got more exciting. A team of scientists including Southwest Research Institute’s Dr. Christopher Glein has discovered new evidence that the subsurface ocean of Saturn’s moon Enceladus contains a key building block for life. The team directly detected phosphorus in the form of phosphates originating from the moon’s ice-covered global ocean using data from NASA’s Cassini mission. Cassini explored Saturn and its system of rings and moons for over ...

Neuroscientists have long searched for ways to reopen “critical periods” in the brain, when mammals are more sensitive to signals from their surroundings that can influence periods of brain development. Now, researchers at Johns Hopkins Medicine say a new study in mice shows that psychedelic drugs are linked by their common ability to reopen such critical periods, but differ in the length of time the critical period is open — from two days to four weeks with a single dose. The findings, published June 16 in the journal Nature, provide a new explanation for how psychedelic drugs work, say the scientists, and suggest potential to treat a wider ...

Despite some of the most successful international vaccination campaigns in history, the poliovirus continues to circulate around the world, posing a threat of neurological damage and even paralysis to anyone who is not vaccinated. While the original polio strains, called wildtype, have largely been eliminated, new strains can develop from the oral polio vaccine (OPV), which is the one most used in the developing world. Oral vaccines use live, weakened virus that occasionally mutates to an active form, leading to outbreaks even in countries believed to have eliminated polio.  Scientists at UCSF and the UK’s National Institute of Biological Standards and Control (NIBSC) have developed ...

·  Many racial and ethnic groups not well aware of food allergies ·  Lack of food allergy research in racial and ethnic communities ·  ‘These individuals need to be aware so they can be diagnosed and treated’   CHICAGO --- Food allergy has not been on the radar of most racial and ethnic communities. But a new Northwestern Medicine study — the first population-based food allergy study in the U.S. to explore racial and ethnic differences in all age groups — shows why it should be.  The new study found the prevalence of food allergy is highest among Hispanic, non-Hispanic Black and ...

Ants navigate their richly aromatic world using an array of odor receptors and chemical signals called pheromones. Whether foraging or defending the nest, mating or tending to their young, ants both send and receive chemical signals throughout their lives. The importance of this system is underscored by how well equipped the ant brain is to process the abundance of scents: The olfactory processing center in the ant’s brain has 10 times as many subdivisions as fruit flies do, for example, even though their brains are about the same size. And yet how the ant olfactory system encodes scent data has remained largely unknown. To whittle ...

AMHERST, Mass. – A team of physicists, including University of Massachusetts assistant professor Tigran Sedrakyan, recently announced in the journal Nature that they have discovered a new phase of matter. Called the “chiral bose-liquid state,” the discovery opens a new path in the age-old effort to understand the nature of the physical world. Under everyday conditions, matter can be a solid, liquid or gas. But once you venture beyond the everyday—into temperatures approaching absolute zero, things smaller than a fraction ...

Researchers from the UvA Institute of Physics and ENS de Lyon have discovered how to design materials that necessarily have a point or line where the material doesn’t deform under stress, and that even remember how they have been poked or squeezed in the past. These results could be used in robotics and mechanical computers, while similar design principles could be used in quantum computers. The outcome is a breakthrough in the field of metamaterials: designer materials whose responses are determined by their structure rather than their chemical composition. To construct a metamaterial with mechanical memory, physicists ...

When we walk around in our everyday life, we might not think of the Earth itself very often. But this planet is the foundation of our life. The air we breathe, the water we drink and the gravity that pins us to the ground.   Up until now, researchers believed that it took more than 100 million years for the Earth to form. And it was also common belief that water was delivered by lucky collisions with water-rich asteroids like comets. However, a new study from the University of Copenhagen suggests that it might not have happened entirely by chance. “We show that the Earth formed by the very ...

An international team led by Stefan Pelletier, a Ph.D. student at Université de Montréal's Trottier Institute for Research on Exoplanets announced today having made a detailed study of the extremely hot giant exoplanet WASP-76 b. Using the MAROON-X instrument on the Gemini-North Telescope, the team was able to identify and measure the abundance of 11 chemical elements in the atmosphere of the planet. Those include rock-forming elements whose abundances are not even known for giant planets in the Solar System such as Jupiter or Saturn. The team's study is published in ...

The results of a yearlong science program show that one of the best ways to instill a lasting interest in science among children is to engage them alongside their family members. This finding runs counter to the current framework, in which children attend science-related summer camps and after-school programs apart from their families, diminishing the long-term potential of what they learn. “We wanted to see if we could support families as a whole, as opposed to giving a student a really amazing one-off experience and sending them ...

INDIANAPOLIS — In one of the first studies to investigate racial disparities in the pharmacologic treatment of insomnia, researchers from Regenstrief Institute and Indiana University report that patients belonging to racial minority groups were significantly less likely to be prescribed medication following diagnosis of insomnia than White patients. The study found that Black patients were much less likely to have been prescribed an FDA-approved insomnia medication at any time post diagnosis than White patients. Other non-White individuals were significantly less likely to be prescribed an FDA-approved medication two, three, and four years after insomnia diagnosis ...

In a recent study, researchers created a diagnostic test to identify functional sperm in infertile men that could change the treatment of male infertility and assisted reproductive technology. “Male infertility is a recognized issue and deserves scientific and clinical attention,” said Andrei Drabovich, an assistant professor of laboratory medicine and pathology at the University of Alberta and corresponding author of the Molecular & Cellular Proteomics study. One in every six couples trying to conceive experience infertility issues. In fact, about 10% of men in the United States are infertile. The most ...

In the early 2000s, scientists from the UK made a worrisome discovery that the oceans are teeming with small particles of plastic (less than one millimeter in length) due to the continuous degradation of plastic waste. These microscopic particles of plastic have become a major environmental concern. Scientists classify these small particles as either microplastics or nanoplastics based on their size; the latter term is used exclusively for particles smaller than one micrometer. These particles easily get embedded into the bodies of marine and freshwater animals, ...

The neuromorphic invention is a single chip enabled by a sensing element, doped indium oxide, that’s thousands of times thinner than a human hair and requires no external parts to operate. RMIT University engineers in Australia led the work, with contributions from researchers at Deakin University and the University of Melbourne. The team’s research demonstrates a working device that captures, processes and stores visual ...

SDE BOKER, Israel, June 14, 2023 – Photovoltaic technology is indispensable for our ability to mitigate climate change. Nonetheless, more than 70% of the energy made available to us by the sun is wasted in conventional photovoltaic cells. There is little hope for sustainable technological advancement without addressing this issue. The operational temperature is a critical factor in a solar cell's ability to convert sunlight to free energy. Accordingly, much research has been directed toward understanding the temperature effects in the efficiency of photovoltaic solar cells. Surprisingly, ...

Glucose oxidase (GOx)-based biosensors have attracted much attention for their potential in rapid glucose detection and continuous monitoring, which are crucial for disease diagnosis and prevention, as well as for controllable production in sugar-making and fermentation processes. The glucose oxidase/electrocatalysts/electrode (GOx/ECs/electrode) cascade system serves as the core part of most glucose biosensing devices (both invasive and non-invasive). However, patterned assembly of these cascade sensing units remains challenging, thus limiting the ...

Ishikawa, Japan -- Bone-conduction (BC) headphones enhance hearing capability by generating vibrations in bone or skin close to the ear, including the regio temporalis. They simultaneously leave the ear canal open to allow the surrounding air-conducted (AC) sounds for normal hearing. However, word intelligibility – recognition ability – is often poor during bone-conducted speech perceived using BC headphones due to the attenuation of its high-frequency components, especially under noisy conditions. While inserting ear plugs in the ear canal help improve ...
