Human-AI teams improve healthcare only when clinicians stay in control

A scoping review of 140 empirical studies found that human-AI collaboration in healthcare reports the most consistent benefits in diagnostic interpretation, especially when AI supports bounded tasks and clinicians retain final responsibility. Evidence remains fragmented across triage, treatment planning, and documentation, with few studies measuring patient outcomes, system impact, trust calibration, or governance in real-world settings.

Lost weight is less likely to return when exercise follows obesity treatment

A systematic review and meta-analysis of 11 randomized controlled trials found that exercise during the post-weight-loss maintenance phase reduced weight regain by an average of 2.81 kg compared with control groups. Evidence for fat-mass reduction remained inconclusive, highlighting the need for longer, standardized trials with better adherence and body-composition monitoring.

Early diabetes drug treatment links to better survival after diagnosis thresholds

A Korean target trial emulation found that starting antidiabetic medication within 12 months of newly crossing type 2 diabetes diagnostic thresholds was associated with lower five-year all-cause mortality. MACE risk was numerically lower with earlier treatment, but the reductions in cardiovascular events were not statistically significant, underscoring the need for larger studies.

Strength training plus cardio cuts type 2 diabetes risk the most

A 20-year prospective cohort study of 143,715 US healthcare professionals found that long-term resistance training was associated with a substantially lower risk of type 2 diabetes. The lowest risk was seen among participants who combined regular resistance training with adequate aerobic activity and limited TV viewing.

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.

Colorectal cancer cases rise among younger adults in Germany

Colorectal cancer is generally considered a disease of older adults. However, a new analysis of German cancer registries shows that the number of new colorectal cancer cases among younger adults has risen slightly over the past two decades.

Scientists unlock molecular structure of key protein linked to cancer, neurological diseases

After nearly four decades of research, Mayo Clinic scientists have revealed the molecular structures of protein kinase C beta (PKCβ), a key protein linked to cancer and neurological diseases.

Circadian rhythm influences calorie burning after eating

Han-Chow Koh, PhD, and Frank A.J.L. Scheer, PhD, of the Medical Chronobiology Program at the Division of Sleep and Circadian Medicine in the Mass General Brigham Department of Medicine, are the co-lead and senior author, respectively, of a paper published in Metabolism, "Constant-routine protocol reveals an endogenous circadian rhythm in diet-induced thermogenesis with a peak in the biological morning."

Study uncovers sex-specific immune pathway driving glioblastoma growth

Researchers have identified a critical biological difference in how glioblastoma develops in male and female laboratory models, pinpointing an immune pathway that fuels tumor growth only in females.

Gene therapy shows promise against deadly childhood liver disease

A new gene therapy has been used to successfully treat a deadly childhood liver disease using mice that model this disease by researchers at UCL and Great Ormond Street Hospital.

Family court care proceedings increase mortality risk among first-time mothers

First-time mothers whose children go through family court care proceedings in England are 21 times more likely to die within 10 years of having their baby compared with other mothers, a new study by UCL researchers finds.

Sugar-coated nanoparticles extend survival in aggressive glioblastoma mouse model

Researchers at Oregon State University have potentially found a new way to treat the most aggressive form of brain cancer, glioblastoma, whose two-year survival rate is less than 30%.

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.

Cambridge researchers discover three distinct severe pneumonia biological subtypes

Cambridge researchers have shown that severe pneumonia has three different subtypes, helping explain why some patients in intensive care units (ICUs) recover from their illness faster than others, while for other patients the disease can be life-threatening.

A night without sleep alters neural connections in human brains

A night without sleep produced increased markers of connections between brain cells, showing that sleep in humans may be important for restoring cellular balance in the brain, according to a study published June 23rd in the open access journal PLOS Biology by David Elmenhorst from the Forschungszentrum Jülich Institute of Neuroscience and Medicine in North Rhine-Westphalia, Germany, and colleagues.

AI image-based risk scores enable dynamic breast cancer assessment

Using artificial intelligence (AI), researchers found that image-based risk scores for breast cancer derived from screening mammograms evolve over time and differ between women who develop cancer and those who do not, opening the door to a new era of dynamic breast cancer risk assessment.

Scientists uncover new molecular mechanism driving gastrointestinal stromal tumors

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the digestive tract, with KIT mutations driving approximately 75% to 80% of cases.

USC study links modified Mediterranean diet to longer lifespan

A plant- and fish-based, low-protein diet paired with small amounts of an amino acid commonly found in eggs, meat and dairy increased healthy lifespan and decreased frailty and fat mass in mice, according to a new USC study published today in the journal Cell Metabolism.

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.
