An international team gauges the coming threat of mosquito-borne diseases — ScienceDaily

Outbreaks of mosquito-borne illnesses like yellow fever, dengue, Zika and chikungunya are rising around the world. Climate change has created conditions favorable to mosquitoes’ spread, but so have human travel and migration and accelerating urbanization, creating new mini-habitats for mosquitoes. In today’s Nature Microbiology, a large group of international collaborators combined these factors into prediction…

TIGER mouse debuts as model for neurological ailments — ScienceDaily

New research published today in Scientific Reports has devised a way to track tiny message-carriers in the brain that could prove useful in diagnosing and treating injuries, infections or diseases. The study, from assistant professor David Feliciano’s lab in Clemson’s College of Science, uses a glowing mouse — appropriately dubbed the “TIGER mouse” — to…

Are mosaic embryos the ‘dark horse’ of IVF?

Not every embryo contains 46 perfect chromosomes. Some have more, others have fewer. The result is a common abnormality known as aneuploidy, which occurs in as many as 80 percent of human embryos. Because aneuploidy has been linked to a risk of in vitro fertilization failure, miscarriage and certain genetic orders or birth defects, mosaic…

‘Broken heart’ syndrome may originate in the brain — ScienceDaily

Scientists have shown for the first time that the brain is involved in the development of a heart condition called Takotsubo syndrome (TTS). They found that regions of the brain responsible for processing emotions and controlling the unconscious workings of the body, such as heart beat, breathing and digestion, do not communicate with each other…

Theory shows how monocrystals of hexagonal boron nitride come together — ScienceDaily

Very small steps make a big difference to researchers who want to create large wafers of two-dimensional material. Atom-sized steps in a substrate provide the means for 2D crystals growing in a chemical vapor furnace to come together in perfect rank. Scientists have recently observed this phenomenon, and now a Rice University group has an…

Ultracold atoms could provide 2D window to exotic 1D physics — ScienceDaily

Rice University physicists Matthew Foster and Seth Davis want to view a vexing quantum puzzle from an entirely new perspective. They just need the right vantage point and a place colder than deep space. “There’s a process in strongly interacting physics where fundamental particles, like electrons, can come together and behave as if they were…

Opening door to smaller memory devices, microelectronics, and spintronics — ScienceDaily

A research team led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has created a nanoscale “playground” on a chip that simulates the formation of exotic magnetic particles called monopoles. The study — published recently in Science Advances — could unlock the secrets to ever-smaller, more powerful memory devices, microelectronics, and next-generation…

The case of the over-tilting exoplanets — ScienceDaily

For almost a decade, astronomers have tried to explain why so many pairs of planets outside our solar system have an odd configuration — their orbits seem to have been pushed apart by a powerful unknown mechanism. Yale researchers say they’ve found a possible answer, and it implies that the planets’ poles are majorly tilted.…

Unique Weyl semimetal delivers largest intrinsic conversion of light to electricity — ScienceDaily

A recently discovered Weyl semimetal delivers the largest intrinsic conversion of light to electricity of any material, an international team lead by a group of Boston College researchers reports today in the journal Nature Materials. The discovery is based on a unique aspect of the material where electrons can be separated by their chirality, or…

P. falciparum parasites can develop drug resistance by epigenetic changes in clag3 gene expression — ScienceDaily

Resistance to antimalarial drugs is thought to result mainly from changes in the parasite’s genome. However, P. falciparum can also develop resistance to some antimalarial compounds by epigenetic changes, according to a new study led by ISGlobal, an institution supported by “la Caixa,” and the Institute of Tropical Medicine (ITM), Antwerp. This is of concern…
