Harmful protein waste in the muscle

An international research team identified the cause of a rare muscle disease. According to these findings, a single spontaneously occurring mutation results in the muscle cells no longer being able to correctly break down defective proteins. The condition causes severe heart failure in children, accompanied by skeletal and respiratory muscle damage. The study also highlights experimental...

Biodiversity 'hotspots' imperiled along California's streams

A study of woodland ecosystems that provide habitat for rare, endangered species along streams, rivers throughout California reveals some ecologically important areas are inadvertently benefiting from water humans are diverting for their own needs. Though it seems a short-term boon to these ecosystems, the artificial supply creates an unintended dependence on its bounty, threatens the long-term...

Making a meal of DNA in the seafloor

While best known as the code for genetic information, DNA is also a nutrient for specialized microbes. An international team of researchers has discovered several bacteria in sediment samples from the Atlantic Ocean that use DNA as a food source. One bacterium newly named by the team in fact is a true expert in degrading DNA.

Insulators turn up the heat on quantum bits

Physicists have long suspected that dielectric materials may significantly disrupt ion-trap quantum computers. Now, researcher have developed a new method to quantify this source of error for the first time. For the future operation of quantum computers with very many quantum bits, such noise sources need to be eliminated already during the design process if possible.

The evolution of good taste

Does evolution explain why we can't resist a salty chip? Researchers found that differences between the elemental composition of foods and the elemental needs of animals can explain the development of pleasing tastes like salty, umami and sweet.

New combination of materials provides progress toward quantum computing

Engineers have demonstrated how, when the TMDC materials they make are stacked in a particular geometry, the interaction that occurs between particles gives researchers more control over the devices' properties. Specifically, the interaction between electrons becomes so strong that they form a new structure known as a correlated insulating state. This is an important step, researchers said, toward...

Scientists expose the cold heart of landfalling hurricanes

Fearsome and powerful, hurricanes can wreak massive destruction when they hit land. But while most hurricanes then weaken, others can strengthen again into extratropical cyclones and caused further damage inland. Now, researchers have used simulations to uncover the presence of a cold core inside decaying hurricanes - an unexpected discovery that could help forecasters predict the level of extreme...

Peering inside 2D crystal synthesis

Theorists simulate the molecular transitions that take place inside a furnace to create 2D molybdenum disulfide, a semiconductor that could find a home in next-generation electronics.

Potential new treatment target for Alzheimer's disease

A new study not only sheds light on how the APOE4 gene may cause some of the pathologies associated with Alzheimer's disease, but also suggests a new treatment target that might help people who carry the APOE4 gene in early and late stages of the disease. Researchers found that APOE4 is associated with the activation of an inflammatory protein that causes a breakdown in the blood-brain barrier...

A new model of Alzheimer's progression

Scientists explore how protein and signaling pathways change in patients with Alzheimer's disease. Their work creates a new model of disease progression, taking advantage of the heterogeneity that is inherent to human studies.
