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.

Polyglycerol coating: A breakthrough in safer nanoparticle environmental remediation      (via sciencedaily.com)     Original source 

Engineered nanoparticles (NPs), commonly utilized in environmental remediation, can pose significant toxicity risks upon ingestion by organisms. Researchers have now devised a solution to this challenge by creating a hydrophilic coating, utilizing polyglycerol (PG) functionalization, for NPs. This coating effectively prevents NP aggregation inside organisms' bodies and facilitates easier passage, thereby reducing accumulation. Applicable to various NPs, the novel surface functionalization approach holds promise for addressing concerns about NP toxicity in environmental remediation.

Climate change is most prominent threat to pollinators      (via sciencedaily.com)     Original source 

A new article has found that climate change is the most prominent threat to pollinators -- such as bumblebees, wasps, and butterflies -- who are essential for biodiversity conservation, crop yields and food security. The research suggests that many of the threats to pollinators result from human activities.

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.

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.
