In a breakthrough mouse study, researchers used a compound called JQ1 to temporarily shut down meiosis—the critical process that produces sperm—without causing lasting harm. After treatment stopped, sperm production bounced back, fertility returned, and the animals produced healthy offspring.

By tracking how sperm use glucose as fuel, the team discovered how dormant cells suddenly flip into overdrive, burning energy in a carefully controlled, multi-step process. A key enzyme, aldolase, helps convert sugar into the burst of power needed for fertilization, while other enzymes act like traffic controllers directing the flow of fuel.

Inside the capsule is a biodegradable antenna that sends a signal within minutes of ingestion, then safely dissolves. The system is designed to work with existing medications and could help doctors track adherence for high-risk patients. Researchers hope it will prevent missed doses that can lead to serious health consequences.

Older adults with weaker, more disrupted activity patterns were far more likely to develop dementia than those with steady routines. A later daily energy peak was also linked to higher risk. The study points to the body clock as a possible early warning sign for cognitive decline.

Insurance marketing often overshadows unbiased options like SHIP, leaving people unaware of better choices. Comparing real costs—not just premiums—can prevent unpleasant surprises, especially when provider networks or drug rules change.

The pill also improved cardiovascular risk factors and physical activity levels. With a safety profile consistent with existing treatments, experts see it as a breakthrough for patients preferring oral options.

The results hint that intimacy itself can curb genitourinary syndrome of menopause, a cluster of estrogen-related symptoms that erode quality of life.

In order to transmit from the human host to the mosquito vector, the parasite has to differentiate to its sexual stage, referred to as the gametocyte stage. Unlike primary sex determination in mammals, which occurs at the chromosome level, it is not known what causes this unicellular parasite to form males and females. New research has implemented high-resolution genomic tools to map the global repertoire of genes of gametocyte development towards the male or the female sexual fates.

The magnetic field can induce an electric field in any nearby neurons, the same effect created by an electrode but much more precise. They used an array of eight coils, which combined can induce electric fields using much less current per coil, and employed soft magnetic materials, which boost the magnetic strength of the coils. The researchers constructed a prototype of their coil array, called MagPatch, and encapsulated it within a biocompatible coating.

This irregular heartbeat is associated with increased risks of heart failure, dementia and stroke. It constitutes a significant burden to healthcare systems, making its early detection and treatment a major goal. Researchers have recently developed a deep-learning model capable of predicting the transition from a normal cardiac rhythm to atrial fibrillation. It gives early warnings on average 30 minutes before onset, with an accuracy of around 80%. These results pave the way for integration into wearable technologies, allowing early interventions and better patient outcomes.

Most cells in mammalian bodies have cilia of some sort, which are hair-like structures that perform a variety of functions such as movement for motile cilia and aiding in structure in function for non-motile, or primary, cilia. The primary cilia also act as a sensory organ for the cell, a function which has illuminated the primary cilia's potential role in the healing process and how bodies heal at a different rate according to our circadian rhythm. In this research, the role of the primary cilia, biological clock and wound healing is explored.

Researchers identified expression of the gene, Arrdc5, in the testicular tissue of mice, pigs, cattle and humans. When they knocked out the gene in mice, it created infertility only in the males, impacting their sperm count, movement and shape.
