The Hypothalamus is the area of the brain that controls body temperature, hunger, and thirst.

Degeneration in two brain regions causes severe narcolepsy symptoms

For nearly 25 years, scientists believed they knew what caused the most severe form of narcolepsy. A new UCLA Health study now suggests they were only half correct.

Researchers map how menstrual cycle phases affect athletic performance

In a repeated-measures study of 18 eumenorrheic female athletes, half-squat strength was highest in the late follicular phase and around ovulation, while handgrip strength peaked in the late luteal phase. Psychological measures also shifted across the cycle, with lower vigor and higher fatigue and depression scores in the late luteal phase, supporting more individualized training monitoring.

AI analyzes Reddit posts to find underreported GLP-1 side effects

By using AI to analyze more than 400,000 Reddit posts, Penn researchers have identified patient-reported symptoms associated with GLP-1s, the popular weight-loss and diabetes drugs semaglutide and tirzepatide, that may not be fully captured in clinical trials or regulatory documents.

Chronotherapy offers new hope for timing pain relief to match body cycles

Time plays a key role in our perception of pain and administering pain relief and medication for chronic pain-related depression may be more effective at certain times of day, UCL and University of Toronto researchers say.

Python blood compound could lead to new weight loss therapies

University of Colorado Boulder researchers have discovered an appetite-suppressing compound in python blood that helps the snakes consume enormous meals and go months without eating yet remain metabolically healthy.

Study identifies immune cells and RANK protein as fertility regulators

The kick off signal for puberty begins in the brain. Specifically, in the hypothalamus, where specific neurons release a hormone that activates the hypophysis, at the base of the skull, which then releases other hormones to start gonad –ovaries or testicles –maturation.

Early exposure to unhealthy foods leaves lasting brain and feeding changes

Eating unhealthy foods early in life leave lasting brain and feeding changes but gut bacteria can help restore healthy eating, new University College Cork (UCC) research study finds today (Tuesday 24th February 10am)

Brain neurons after exercise drive long-term endurance gains

When you finish a run, your muscles may feel like they did all the work. But researchers at The Jackson Laboratory (JAX) and the University of Pennsylvania (UPenn) have discovered that what happens in your brain after a run may determine whether you gain endurance over time.

Onset of "the munchies" after cannabis use could offer clues to help people with appetite loss

The urgent onset of "the munchies" after cannabis use isn't imaginary – it's a cognitive response that occurs regardless of sex, age, weight or recent food consumption and could offer clues to help people struggling with appetite loss.

Key protein regulates slow oxytocin release in the brain

The brain does not only communicate through fast electrical impulses; it also relies on slower, more diffuse chemical signals that modulate our emotional and social states over time.

How GLP-1 drugs affect the body beyond weight loss and glucose control

This review evaluates the safety profile of glucagon-like peptide-1 receptor agonists and related incretin therapies used for obesity and type 2 diabetes. It highlights common gastrointestinal effects, rare but debated risks, and areas where further long-term safety data are still needed.

Exercise-induced activation of neurons mediates improvements in endurance

Exercise does more than strengthen muscles; it also rewires the brain. In a study publishing February 12 in the Cell Press journal Neuron, researchers reveal that the lasting gain in endurance from repeated exercise-such as the ability to run farther and faster over time-involves changes in brain activity that help muscles and hearts to become stronger.

Brain circuit links past experiences to appetite control

Our past experiences shape how much we eat and where and what we choose to eat. Using preclinical models, researchers from Mass General Brigham and the Broad Institute of MIT and Harvard have identified brain cells that translate contextual information into appetite control.

Ageing slows brain protein clearance and shifts synaptic waste to microglia

Ageing slows neuronal protein degradation in mice, leading to widespread accumulation and aggregation of long-lived proteins, particularly at synapses. As neuronal clearance declines, microglia selectively accumulate synaptic proteins, suggesting a compensatory but potentially strained proteostasis pathway in the ageing brain.

Fish study reveals how ovulation triggers sexual receptivity in females

A research team led by Hiroshima University and Tokyo University of Agriculture and Technology have proposed a neuroendocrine mechanism in bony fish that signals ovulation from the ovaries to the brain, using the medaka fish as a model; the first step to elucidate the neural circuits for facilitation of sexual receptivity in female teleosts.

The gut is not just digestive and new evidence shows it actively controls brain function

This comprehensive review synthesizes a decade of human and animal research to explain how the gut and brain communicate through hormonal, neural, immune, and microbial pathways. It highlights how disruptions in these pathways contribute to gastrointestinal, metabolic, and neurological disorders, and how modern therapies are beginning to exploit gut–brain signaling for clinical benefit.

Altered stress signaling helps explain relapse in alcohol use disorder

A new study by Scripps Research reveals that alcohol dependence disrupts two signaling pathways in a stress-related part of the brain-and offers insights on developing drugs to treat this condition.

Breast cancer disrupts stress hormone rhythms in the brain

"The brain is an exquisite sensor of what's going on in your body," says Cold Spring Harbor Laboratory Assistant Professor Jeremy Borniger. "But it requires balance. Neurons need to be active or inactive at the right times. If that rhythm goes out of sync even a little bit, it can change the function of the entire brain."

Brain recordings reveal why food cravings return despite tirzepatide

Researchers investigate the effects of tirzepatide on food preoccupation by influencing the brain’s mesolimbic circuitry.

Study finds GLP-1 drugs improve strength and reverse aging biology in mice

Researchers showed that GLP-1 receptor agonism counteracts aging across multiple organs in mice, improving strength and reversing molecular aging signatures without meaningful effects on body weight. These benefits depended largely on hypothalamic GLP-1R signaling and closely mirrored the anti-aging patterns produced by rapamycin.
