Bariatric surgery linked to higher risk of developing alcohol problems

Your body absorbs alcohol much more rapidly after bariatric surgery. Patients need to know this when they choose the kind of surgery they will have.

Gene linked to lower BMI points researchers toward a new obesity target

A review in Cardiology in Review highlights GPR75, a receptor for 20-HETE, as a promising therapeutic target for obesity and metabolic syndrome. Evidence from genetic studies, cell experiments, and mouse models suggests that blocking this pathway could influence weight gain, insulin resistance, hypertension, inflammation, and vascular dysfunction.

Scientists map genetic changes controlling the immune sensor STING

The immune system depends on molecular alarms that detect danger inside cells. One of these alarms is STING, short for "stimulator of interferon genes".

Scientists identify genes linking air pollution to severe asthma

For many people with asthma, air-quality advisories are harbingers of worsening symptoms. But for reasons science has struggled to explain, the extent to which pollution exacerbates asthma varies widely from person to person.

Melatonin improves skin flap survival by reducing ferroptosis

Random-pattern skin flaps are widely used to repair defects caused by trauma, burns, tumor removal, and other injuries because they can be designed without depending on a single named blood vessel.

Study finds no detectable short-term brain harm after one youth soccer season

A prospective European cohort study found that one season of competitive youth soccer was not associated with detectable short-term differences in cognition, behavior, balance, MRI measures, or blood biomarkers compared with noncontact sports. However, soccer players had higher preseason tNAA, GFAP, and NfL levels than controls, highlighting the need for larger, multiyear studies to clarify whether repeated heading has cumulative effects.

Researchers identify molecular pathway that delays diabetic wound healing

Diabetic foot ulcer (DFU) is one of the most serious complications of diabetes and a major cause of lower-limb amputation.

Scientists discover how fat tissue drives the spread of triple-negative breast cancer

Triple-negative breast cancer (TNBC) is aggressive and hard to treat. But the role of fat tissue in how the cancer spreads may help point toward new understanding and treatments, according to a new paper from scientists at the Hackensack Meridian Center for Discovery and Innovation (CDI) and colleagues at Georgetown University's Lombardi Comprehensive Cancer Center.

Aligned heart rates indicate real-world social connection and engagement

When people are close-both physically and emotionally-their heart rates begin to align, rising and falling together. Could such cardiac alignment be used as a way to measure social engagement and connection in everyday settings? Hanlu He and colleagues used data collected by 72 students visiting New York City as part of an audio engineering competition.

Skin barrier monitoring predicts necrosis after skin flap surgery

Random-pattern skin flaps (RPSFs) receive blood mainly from small subcutaneous vessels rather than a defined axial vessel, leaving them vulnerable to ischemia and hypoxia after surgery.

The menstrual cycle changes heart-rate variability but not strength

Menstrual cycle phases influence heart autonomic regulation, showing HRV variations, yet muscle performance and mood states remain largely unchanged.

Trial identifies 4 grams a day as the tested safe level for L-tyrosine in healthy men

A randomized, crossover trial in healthy adult men found that 4 weeks of L-tyrosine supplementation at doses up to 4 g/day did not cause clinically meaningful changes in safety markers, diet, blood pressure, or body measures. The highest tested dose, 4 g/day, was identified as the no-observed-adverse-effect level under the study’s four-week conditions, although broader and longer-term studies are still needed.

Statins may trigger muscle side effects by activating inflammatory danger signals

An experimental study in Science Advances shows that statins, primarily fluvastatin in these experiments, may promote low-level muscle myopathy by reducing isoprenoid-dependent protein prenylation rather than by cholesterol lowering. In primed muscle cells and mouse models, impaired YAP signaling, reduced glycolysis, NLRP3/caspase-1 activation, and nuclear FOXO accumulation increased atrogin-1, reduced protein synthesis, and weakened muscle function.

Scientists trace cardiac aging to a fading regulator in heart muscle cells

Researchers mapped 442,239 single nuclei from nonfailing human hearts to chart how cardiac cells change from fetal development to older adulthood. The study identified PRDM16 as an age-declining cardiomyocyte regulator, with experimental evidence showing that restoring Prdm16 in aged mouse hearts improved systolic function and partly reversed aging-associated transcriptional patterns.

Natural molecule erucamide helps slow progressive retinal degeneration

Many conditions that cause vision loss share a common feature: the gradual breakdown of the retina, the light-sensing tissue at the back of the eye.

Optimized proximity labeling platform tracks cellular protein communication networks

The body's organs are in constant communication. Fat tissue tells the liver when to store or release energy, the immune system signals localized inflammation, and thousands of proteins carry these messages to organs throughout the body.

Most adults with depression favor informal community peer support

As mental health needs continue to rise in Singapore, researchers from Duke-NUS Medical School, working with collaborators, including the Institute of Mental Health (IMH), have found that most adults living with symptoms of anxiety or depression are open to receiving support from peers, even if they have not sought professional help.

GATA6 loss transforms colorectal cancer cells into metastatic states

Loss of GATA6-a transcription factor that controls which genes are turned on or off-can reprogram colorectal cancer cells into more primitive, adaptable states that can then spread to the liver and establish new tumors, according to Weill Cornell Medicine and Massachusetts Institute of Technology researchers.

Study links neuroimmune dysregulation to complex fibromyalgia symptoms

Fibromyalgia is a complex disorder characterized primarily by chronic widespread pain, fatigue and other physical and cognitive symptoms.

Study shows positive milestones shape the lives of youth

Which major life events matter to young people? A recent study by the University of Zurich (UZH) shows that adolescents and young adults primarily cite positive, everyday developmental steps as formative events, for example school and apprenticeships, friendships, first relationships, travel and moving out of their parents' home.
