An active agent against hepatitis E      (via sciencedaily.com)     Original source 

At present, there is no specific active substance against hepatitis E. As the disease kills 70,000 people every year, researchers are actively searching for one. A team may have found what they're looking for. The researchers showed that the compound K11777 prevents host cells from helping the virus out of its shell by cleaving the viral capsid. This means it can no longer infect cells.

Exploring the mechanism behind drug eruptions in the skin      (via sciencedaily.com)     Original source 

Although drug eruptions are often linked to the human leukocyte antigen (HLA), the mechanism of its involvement in presenting symptoms of the skin remains unclear. In a recent study, researchers used genetically engineered mice to demonstrate the role of HLA in mediating intracellular reactions in keratinocytes, leading to drug eruptions in the skin. Their findings could lead to improved preventive and treatment measures for drug eruptions.

Drug compounds to combat neurodegenerative diseases      (via sciencedaily.com)     Original source 

Prions are the abnormal, pathogenic agents that are transmissible and are able to induce abnormal folding of specific normal cellular proteins. Prion disease is an umbrella term for a group of fatal and currently untreatable neurodegenerative diseases that not only affect humans, but also wild and captive animals. These diseases include Creutzfeldt-Jakob disease (CJD) in humans, bovine spongiform encephalopathy (BSE, or 'mad cow disease'), and chronic wasting disease (CWD) affecting deer, elk and moose.

A simple quantum internet with significant possibilities      (via sciencedaily.com)     Original source 

It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's possible. That's exactly what physicists have done, using existing Boston-area telecommunication fiber, in a demonstration of the world's longest fiber distance between two quantum memory nodes to date.

Iconic baobabs: The origin and long-distance travels of upside down trees      (via sciencedaily.com)     Original source 

The research cracks the code on the iconic baobab tree's origin story, revealing their surprising origins in Madagascar and incredible long-distance dispersals to Africa and Australia. The study unveils how baobabs developed unique pollination mechanisms -- some attracting hawkmoths, others lemurs, and even bats -- showcasing remarkable evolutionary adaptations. The research sheds light on how climate change has shaped the baobab's distribution and diversification over millions of years, offering valuable insights for understanding plant responses to future environmental shifts.

Some mice may owe their monogamy to a newly evolved type of cell      (via sciencedaily.com)     Original source 

What makes the oldfield mouse steadfastly monogamous throughout its life while its closest rodent relatives are promiscuous? The answer may be a previously unknown hormone-generating cell. Scientists discover the cells and hormones that inspire mice to nurture their young; the same hormones are also present in humans.

Far from toxic, lactate rivals glucose as body's major fuel after a carbohydrate meal      (via sciencedaily.com)     Original source 

Scientists have documented the benefits of lactate burning in exercising humans, but few studies have looked at the role of lactate during rest or after a meal. Exercise physiologists challenged fasting men and women with a carbohydrate meal and then monitored lactate in the blood and fat vs carbohydrate metabolism. They found that lactate buffers glucose from a meal, and that lactate is utilized for energy almost as much as glucose.
