Climate cycles and insect pests drive migration timing of reindeer's North American cousin

Biologists have discovered two unexpected drivers for migration timing that dispute long-held assumptions and provide insight into potential future effects of climate change on caribou. First, the start of migration is synchronized across North America and tied to large-scale, ocean-driven climate cycles. Second, warm, windless summers that favored insect pests lead to poorer maternal health and delayed arrivals at the calving grounds the following spring.

To the brain, straight from the vein: IV treatment for TBI

A team of researchers has found that neural exosomes -- 'cargo' molecules within the nervous system that carry messages to the brain -- can minimize or even avert progression of traumatic brain injury when used as part of a new cell-to-cell messaging technolo

Comet 2I/Borisov is a mysterious visitor from the depths of space -- the first identified comet to arrive here from another star. Hubble images capture the comet streaking though our solar system and on its way back to interstellar space. It's only the second interstellar object known to have passed through the solar system.

Deadly 'superbugs' destroyed by molecular drills

Motorized molecules activated by light target and drill through highly antibiotic resistant bacteria and kill them within minutes. The molecules can open bacteria to attack by drugs they previously resisted. The strategy could be applied to bacterial infections or diseases on the skin, in the lungs or in the gastrointestinal tract.

Zika vaccine protects both mom and fetus, but mom needs a higher dose when pregnant

Researchers showed, for the first time, that a single, higher dose of vaccination to a pregnant mouse safely protects both her and her fetus from the Zika virus. The researchers found that a single, less potent dose was not enough to protect the fetus.

Deforestation, erosion exacerbate mercury spikes near Peruvian gold mining

Scientists have developed a model that can predict the amount of mercury being released into a local ecosystem from deforestation. The research could point toward ways to mitigate the worst effects of mercury poisoning in regions already experiencing elevated mercury levels caused by small-scale gold mining practices, such as those in the Peruvian Amazon.

Importance of breastfeeding in preventing diabetes reaffirmed in rat study

New research published today shows that breastfeeding is crucial in preventing diabetes. The World Health Organization recommends breastfeeding as the sole source of nutrition for infants until six months of age, as this helps reduce child morbidity and mortality. In contrast, early weaning is associated with both the development of obesity and Type 2 diabetes in adulthood.

Flipping the script on novel cancer therapy leads to insights into lupus

In the last decade, scientists discovered that blocking a key regulator of the immune system helped unleash the body's natural defenses against several forms of cancer, opening up a new era of cancer immunotherapy. Now scientists have essentially flipped this script and found that when impaired a molecularly similar regulator can cause the damaging immune system attacks on skin and organs that are the hallmark of the autoimmune disease lupus.
