Scientists make pivotal discovery of method for wireless modulation of neurons with X-rays that could improve the lives of patients with brain disorders. The X-ray source only requires a machine like that found in a dentist’s office.
Many people worldwide suffer from movement-related brain disorders. Epilepsy accounts for more than 50 million; essential tremor, 40 million; and Parkinson’s disease, 10 million.
Researchers Mario Guarracino the HSE Laboratory of Algorithms and Technologies for Networks Analysis in Nizhny Novgorod and Julius ?ilinskas and Algirdas Lančinskas from Vilnius University, have proposed a new method of testing for COVID-19. This group method allows results to be obtained 13 times faster as compared to individual testing of each sample.
In the heart of black cherry's native range, including a part of the Allegheny Hardwoods that bills itself as the "Black Cherry Capital of the World," the tree's regeneration, growth and survival have all been declining for more than a decade. In a new analysis, a team of USDA Forest Service and University of Missouri scientists identify likely factors behind the tree's decline and, more significantly, conclude that black cherry may be the tip of the iceberg in terms of change in eastern deciduous forests.
URBANA, Ill. - Pumpkin growers dread the tiny tan scabs that form on their fruit, each lesion a telltale sign of bacterial spot disease. The specks don't just mar the fruit's flesh, they provide entry points for rot-inducing fungus and other pathogens that can destroy pumpkins and other cucurbits from the inside out. Either way, farmers pay the price, with marketable yields reduced by as much as 90%.
Cambridge, MA - Astronomers have now obtained a new view of the supermassive black hole at the center of galaxy M87. Images released today by the Event Horizon Telescope (EHT) collaboration reveal how the black hole, some 55 million light-years away, appears in polarized light.
The image marks the first time astronomers have captured and mapped polarization, a sign of magnetic fields, so close to the edge of a black hole.

Philadelphia, March 25, 2021 - Anabolic androgenic steroids (AAS), a synthetic version of the male sex hormone testosterone, are sometimes used as a medical treatment for hormone imbalance. But the vast majority of AAS is used to enhance athletic performance or build muscle because when paired with strength training. AAS use increases muscle mass and strength, and its use is known to have many side effects, ranging from acne to heart problems to increased aggression.
Curtin University research has uncovered the first solid clues about the very beginning of the supercontinent cycle of Earth, finding it was kick-started two billion years ago.
Detailed in a paper published in Geology, a team of researchers from Curtin's Earth Dynamics Research Group found that plate tectonics operated differently before two billion years ago, and the 600 million years supercontinent cycle likely only started during the second half of Earth's life.
Deforestation, certain types of reforestation and commercial palm plantations correlate with increasing outbreaks of infectious disease, shows a new study in Frontiers in Veterinary Science. This study offers a first global look at how changes in forest cover potentially contribute to vector-borne diseases--such as those carried by mosquitos and ticks--as well as zoonotic diseases, like Covid-19, which jumped from an animal species into humans.
Research shows that children prefer to befriend, listen to, and imitate people who speak similarly to them. While most of this research has been conducted on monolingual (speaking only one language) children from Western societies, a growing subset of research has begun examining whether this pattern holds for children from more diverse linguistic and cultural backgrounds. A new meta-analysis including studies with monolingual as well as bilingual children helps to shed light on the range of factors that contribute to the development of linguistic-based biases in early childhood.
A new study shows that if the population were fixed at current levels, the risk of population displacement due to river floods would rise by ~50% for each degree of global warming. However, if population increases are taken into account, the relative global flood displacement risk is significantly higher.
The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole, has revealed today a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the M87 galaxy, located 55 million light-years away, is able to launch energetic jets from its core.

A new study suggests that Sargramostim, a medication often used to boost white blood cells after cancer treatments, is also effective in treating and improving memory in people with mild-to-moderate Alzheimer's disease. This medication comprises of a natural human protein produced by recombinant DNA technology (yeast-derived rhu GM-CSF/Leukine®).
