Elite athletes with higher vitamin D show healthier lipid profiles

Higher serum 25-hydroxyvitamin D levels were independently associated with lower LDL-C, triglycerides, and lipoprotein(a) in 773 male professional athletes. The cross-sectional study cannot establish causality, but it suggests that vitamin D status may be linked to cardiovascular risk-related lipid markers, even in elite athletic populations.

50-year review shows global Ebola spread remains rare despite outbreak fears

Researchers reviewed Ebola disease cases outside Africa from 1976 to May 2026 and found only 28 confirmed epidemic-linked cases, most involving medical evacuation or occupational exposure. Only four latent travelers were diagnosed after border screening, suggesting that undetected intercontinental spread remains rare when outbreaks are controlled at source.

Andes virus cases on MV Hondius highlight hidden risks of confined travel

A Eurosurveillance report describes a multi-country response to an Andes virus outbreak linked to the Dutch-flagged expedition cruise ship MV Hondius, with 13 cases and three deaths reported as of June 18, 2026. Investigators found evidence consistent with an initial zoonotic infection before embarkation, followed by likely person-to-person transmission among passengers and crew in a confined ship setting.

Accelerated biological aging may drive rising early-onset cancer risk

Cancer is often considered a disease of aging. Older adults are at higher risk because they have had more time to accumulate cellular damage that can trigger tumor formation.

Psychological traits may uncover why Alzheimer’s biology differs between patients

In 822 deceased older adults from ROS and MAP, researchers linked stable psychological traits to multi-omic molecular subtypes of Alzheimer’s dementia using postmortem brain tissue from the dorsolateral prefrontal cortex. Neuroticism and loneliness were associated with molecular progression, while purpose in life showed subtype-specific inverse associations, suggesting psychological traits may align with Alzheimer’s biology beyond conventional neuropathology.

Amazon land use patterns reveal where vector-borne diseases collide

Researchers found that malaria-Chagas and dengue-ATL hotspots in the Brazilian Amazon aligned with distinct agrarian, socioeconomic, and environmental landscapes. The findings suggest that disease surveillance should account for land use, poverty, forest structure, mining, and local livelihoods rather than treating each infection in isolation.

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.

Prime and pull vaccine approach prevents genital herpes infection

Genital herpes is a lifelong infection. While available treatments can manage symptoms, they cannot cure the infection or prevent transmission.

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.

Brainstem neurons found to control attention by suppressing distractions

Neurons tucked away in an ancient part of the brain control the ability to pay attention by suppressing distractions and directing focus.

Australian research uncovers how the brain manages unexpected sensory surprises

Australian researchers have uncovered what happens behind the scenes in our brain when we're faced with a predictable situation versus a surprise, giving vital clues in a long-standing mystery in neuroscience.

Copper-induced cell death stimulates antitumor immune cell responses

A preclinical study from researchers at The University of Texas MD Anderson Cancer Center, published today in Cell, details a connection between the immune system and cuproptosis, a type of copper-induced cell death.

Engineered CAR-T cells offer potential rheumatoid arthritis cure

For the 18 million people living with rheumatoid arthritis, disease management currently means a lifetime of injections-a reality that new research from Tsinghua University may soon begin to change.

New miniature microscope stably images brain cells during movement

Researchers at Peking University have developed DUET, a breakthrough dual-color miniature two-photon microscope that overcomes two persistent barriers in neuroscience imaging: motion-induced signal instability and fluorescence channel crosstalk.

Neuroscience research questions traditional markers for cerebellar movement disorders

A new finding by a Virginia Tech neuroscientist at the Fralin Biomedical Research Institute at VTC is challenging the way investigators study chronic neurological disorders such as dystonia, ataxia, and tremor.

Scientists discover protective antibodies with potential to treat West Nile virus

West Nile virus (WNV) is transmitted by mosquitoes and is increasingly relevant for Europe and worldwide. It can cause severe brain infection and death, yet there is no specific antiviral treatment or approved human vaccine.

Novel gene network approach reveals new schizophrenia risk genes

Scientists have long known that schizophrenia runs in families, but pinpointing exactly which genes contribute to risk has been like searching for needles in a haystack.

New vaccines successfully boost frontline immune cells against HIV

T-cells are the immune system's frontline defenders with a crucial role in controlling HIV. In a milestone clinical trial published in the Journal of Clinical Investigation, researchers with the UNC Institute for Global Health and Infectious Diseases (IGHID) at the UNC School of Medicine have demonstrated that new vaccines can significantly boost T cells targeting the most vulnerable, conserved regions of HIV-areas considered key to effective immune control.

Plague emerged earlier than thought and hit hunter-gatherers hard

Ancient DNA from 46 Lake Baikal hunter-gatherers revealed two early plague outbreak phases about 5,500 years ago, with Yersinia pestis detected in 18 individuals. The findings suggest these basal plague strains caused lethal, child-heavy outbreaks long before dense farming societies, cities, or classical flea-borne bubonic plague emerged.
