Could scorpion venom inspire new treatments for liver disease?

Scorpion venom peptides show promising anti-inflammatory, antiviral, analgesic, and immunomodulatory effects, with experimental evidence suggesting that some candidates could target pathways involved in chronic liver disease and viral hepatitis. The review highlights Kv1.3-blocking peptides and antiviral compounds as potential therapeutic leads, while emphasizing that limited hepatic efficacy data, poor pharmacokinetics, immunogenicity, and manufacturing challenges must be overcome before clinical translation.

Study reveals evolutionary advantage of human heel-first walking style

The average person takes thousands of steps each day, instinctively walking heel-to-toe. Although they hardly register them, those consistent heel-first strides are more unique to humans than previously thought and allowed early hominins to walk farther more efficiently, but at the cost of higher impact forces on bones and joints, according to a new study led by a researcher at Penn State.

LSD deconstruction reveals promising new drug candidates

University of California, Davis researchers have stripped down LSD to the base features responsible for its hallucinogenic and therapeutic effects.

Scientists discover new mechanism for bacterial fosfomycin resistance

Bacteria can survive antibiotics in several ways, including by pumping the drugs out of their cells before they can take effect.

The vaginal microbiome may be an overlooked reservoir of antibiotic resistance

Researchers analyzed 1,957 vaginal metagenomic samples from 1,547 pregnant women and found that bacterial community structure was strongly associated with the diversity and distribution of clinically relevant antibiotic resistance genes. Lactobacillus crispatus-dominated communities carried comparatively few acquired resistance genes, while L. iners-dominated and anaerobe-rich communities showed greater resistance diversity, with PPROM associated with broader predicted resistance profiles among ARG-positive samples.

Psilocybin microdosing sounds promising, but the strongest studies tell a different story

A systematic review of 11 studies involving 3,262 adults found that psilocybin mushroom and truffle microdosing was associated with reported improvements across areas including mental health, well-being, cognition, creativity, and social functioning. However, the evidence was methodologically weak and highly heterogeneous, the two placebo-controlled trials found no significant improvements, and inadequate adverse-event reporting means efficacy and safety remain uncertain.

Deep sleep brain activity helps mice resist social stress

Most adult sleep is non-rapid eye movement (REM), which is restorative and promotes resilience to stressful conditions. However, the brain mechanisms for non-REM sleep's relationship to stress resilience remain unclear.

Inhibitory neurons act as a brake on brain tumor growth

Brain tumors do not grow in isolation. They develop within the highly active environment of the brain, where neurons continuously exchange electrical and chemical signals.

Elusive stem cells offer clues to treat lumbar spinal stenosis

Researchers at Weill Cornell Medicine and Hospital for Special Surgery have discovered the stem cells—unspecialized cells that can develop into specific cell types—that give rise to the body's tendons and ligaments, the tissues connecting muscles and bones.

Psilocybin protects sensory nerves from chemotherapy damage in preclinical study

In mouse models, prophylactic psilocybin prevented or reduced multiple features of chemotherapy-induced peripheral neuropathy, with cycle-matched dosing sustaining protection during repeated cisplatin exposure without measurably affecting tumor growth. Experiments in human-derived sensory neurons and ex vivo peripheral nerves linked the effect to 5-HT2A-dependent preservation of mitochondrial trafficking and local axonal energy supply, while a nonhallucinogenic 5-HT2A agonist reproduced protection against mechanical hypersensitivity.

Microplastics transport toxins and antibiotic resistance across ecosystems

Microplastics are often viewed as pollutants in their own right, but their environmental impact may extend far beyond the plastic particles themselves.

New study uncovers bacterial route to testosterone production

Many prostate cancers depend on androgen hormones, including testosterone, to grow. That is why treatments for advanced disease often try to reduce testosterone production or block its effects.

New V-UNet model improves efficient medical image segmentation

Segmentation tools help doctors identify and delineate tumors, lesions, and other abnormalities in medical images.

Mitochondrial stress triggers long-term protection against heart damage

Mitochondria are popularly known as the "powerhouse of the cell," but these cellular structures do so much more-including acting as signaling hubs.

Younger and older brains respond differently to traumatic injury

Conventional wisdom holds that younger brains are better equipped to recover from injury. Their greater flexibility allows them to adapt, rebuild connections and compensate for damage in ways older brains often cannot.

High-energy tissues rely on macrophages to clear cellular waste

The body's heart muscle (for pumping blood), skeletal muscle (for movement and posture), and brown fat (for heat production), each require a lot of energy and make a lot of waste. And that waste needs to be managed.

Researchers uncover how Atg2 drives autophagosome formation

Autophagy is an intracellular degradation mechanism in eukaryotes. The autophagosome, which encloses damaged or excess cellular material for degradation, is constructed from lipids supplied by the endoplasmic reticulum (ER), via the lipid transfer protein Atg2.

Gut bacterial metabolite linked to inflammation in liver disease

Researchers have identified a link between specific activities in gut bacteria and the liver disease PSC.

Dual-drug microneedle patch targets inflammation and fat browning

The worldwide obesity crisis has become a dominant public health crisis across the globe. Over 3 billion people worldwide currently suffer from obesity, and forecasts warn the number will rise above 4 billion by 2035, accounting for more than half the global population.
