New test could detect Alzheimer’s disease 3.5 years before clinical diagnosis

New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London has established a blood-based test that could be used to predict the risk of Alzheimer’s disease up to 3.5 years before clinical diagnosis. The study, published in the journal Brain, supports the idea that components…

Starry tail tells the tale of dwarf galaxy evolution

A giant diffuse tail of stars has been discovered emanating from a large, faint dwarf galaxy. The presence of a tail indicates that the galaxy has experienced recent interaction with another galaxy. This is an important clue for understanding how so called “ultra-diffuse” galaxies are formed. Astronomers using the Subaru…

New technology may help inform brain stimulation

Brain stimulation, such as Deep brain stimulation (DBS), is a powerful way to treat neurological and psychiatric disorders. While it has provided therapeutic benefit for sufferers of Parkinson’s, Alzheimer’s, and addiction for more than a decade, its underlying neural mechanism is not yet fully understood. Researchers at the Queensland Brain…

Researchers map the effects of dietary nutrients on disease

Researchers at the Francis Crick Institute and King’s College London have created a tool to predict the effects of different diets on both cancerous cells and healthy cells. Their work could help disentangle the subtle metabolic changes associated with different types of nutrients, and improve our understanding of the link…

Stability of perovskite solar cells reaches next milestone

The material class of halide perovskites is seen as a great hope for even more solar power at even lower costs. The materials are very cheap, can be processed into thin films with minimal energy input and achieve already efficiencies that are significantly higher than those of conventional silicon solar…

Mercury helps to detail Earth’s most massive extinction event

The Latest Permian Mass Extinction (LPME) was the largest extinction in Earth’s history to date, killing between 80-90% of life on the planet, though finding definitive evidence for what caused the dramatic changes in climate has eluded experts. An international team of scientists, including UConn Department of Earth Sciences researchers…

Prairie voles without oxytocin receptors can bond with mates and young

The vital role of oxytocin — the “love hormone” — for social attachments is being called into question. More than forty years of pharmacological and behavioral research has pointed to oxytocin receptor signaling as an essential pathway for the development of social behaviors in prairie voles, humans, and other species,…

Meteorites reveal likely origin of Earth’s volatile chemicals

By analysing meteorites, Imperial researchers have uncovered the likely far-flung origin of Earth’s volatile chemicals, some of which form the building blocks of life. They found that around half the Earth’s inventory of the volatile element zinc came from asteroids originating in the outer Solar System — the part beyond…

Discovery advances biofuel crop that could curb dependence on fossil fuel

Michigan State University researchers have solved a puzzle that could help switchgrass realize its full potential as a low-cost, sustainable biofuel crop and curb our dependence on fossil fuels. Among switchgrass’s attractive features are that it’s perennial, low maintenance and native to many states in the eastern U.S., including Michigan.…
