Prolonged exposure to morphine triggers cells in the spine to release signaling molecules that increase pain sensitivity and dull the relief of the drug. Blocking this activity could improve pain management.

In both a mouse model and the hospital records of more than 3 million children, researchers found a connection between strong immune activation in males and later symptoms of autism spectrum disorder.

Ethologist Jan Langbein and his team trained the cattle as a way to keep solid and liquid cattle waste separate—with the goal of reducing ammonia emissions coming from livestock.

Mice lacking irisin didn’t exhibit the cognition improvements that typically follow exercise, and in mouse models of Alzheimer’s disease, treatment with the hormone reduced cognitive decline.

Long-term administration of the antidepressant fluoxetine was tied to decreased concentrations of about 100 different brain lipids in adolescent macaques, hinting at a potential mechanism underlying the drug’s rare but severe side effects.

Shoring up the tissues that separate neurons and other brain cells from the circulatory system in fruit flies and mice can prolong life in the presence of a tumor.

A study suggests that mutations in the gene that encodes the T1R1/T1R3 taste receptor allowed primates that relied on insects for protein to transition to eating leaves and fruit.

Researchers studying rats claim to have found a novel connection between damage on one side of the brain and problems with the posture or movement of limbs on the opposite side of the body.

Patients in a small trial said their chronic pain improved an average of 90 percent over the course of 15 days, but returned shortly after the electrical stimulation sessions ended.

An analysis of scientists’ networks finds discrepancies in the diffusion of novel ideas through communities.

The storm, which made landfall over the weekend as a Category 4 hurricane and has since weakened, forced the evacuation of multiple Louisiana campuses.

In a retrospective analysis, a team found that an algorithm integrating the gene expression of a tumor with the radiation dose a patient received predicted how well the patient responded to the treatment.

Genetic, transcriptomic, and epigenetic data reveal molecular mechanisms tying these disorders to each other and to immune disfunction.

By studying the vocal behavior of 20 baby bats from birth to weaning, researchers have identified striking similarities between how young humans and bats develop communication skills.

Vesicles containing fragments of the organelles released from stressed adipocytes protect the heart against oxygen deprivation, a study in mice shows.

Research in mice suggests that moderating nerve activity with drugs or electrical pulses could modify tissue immune responses, curtailing the chronic pain often associated with inflammatory conditions.

Researchers discover that rattlesnakes change their rattling frequency when a perceived threat approaches—tricking humans into thinking the snake is closer than it really is.

The makers of the CRISPR-based testing platform, called miSHERLOCK, say it could enable people at home or physicians in resource-limited environments to detect SARS-CoV-2—and eventually, other pathogens.

Engineered antibodies trap and immobilize human sperm in the reproductive tract of female sheep, paving the way for possible use as a nonhormonal contraceptive in people.
