Beef Is Making a Comeback – Does It Fit Into a Healthy Diet?
The USDA’s 2026 dietary guidelines have moved beef to the centerpiece of the food pyramid, signaling a major policy shift after decades of urging Americans to limit red meat. Consumption of beef is climbing in the United States, buoyed by social‑media hype around carnivore diets and the popularity of beef tallow. Health experts, however, caution that the scientific consensus still links high red‑meat intake to heart disease and certain cancers. Meanwhile, climate advocates warn the surge could worsen beef’s already large carbon footprint.

Migraines Could Be Treated by Ramping up the Brain's Cleaning System
Researchers demonstrated that enhancing the brain's glymphatic waste‑clearance system can remove a migraine‑triggering chemical in mice, reducing facial pain symptoms. The approach repurposes a hypertension drug to boost clearance, offering a potential therapy for the one‑third of migraine sufferers who...

The Brain's Cleaning System Can Be Boosted to Rid Alzheimer's Proteins
Researchers identified a drug combination that enhances the brain's glymphatic system, improving clearance of Alzheimer‑related proteins. The regimen pairs a widely used sedative with a medication that prevents dangerously low blood pressure, showing safe and effective removal of amyloid and...

How Working Out Like an Astronaut Can Reduce Back Pain and Slow Ageing
Research on astronauts reveals that microgravity accelerates bone and muscle degradation, mirroring the physiological decline seen in aging adults. In orbit, astronauts lose up to 2 % of bone mass each month and see muscle strength drop 10 % within weeks, reaching...

Boosting the Blood-Brain Barrier Could Avert Brain Damage in Athletes
Repeated head impacts in contact sports have been linked to lasting damage of the blood‑brain barrier (BBB), a finding that may underlie chronic traumatic encephalopathy (CTE). Researchers scanned 47 retired athletes using an MRI contrast agent that only enters brain...

The Success of Machine Mathematicians Shows Us How to Be OK with AI
Mathematicians have long wrestled with computer‑generated proofs, beginning with the 1976 four‑colour theorem solution that relied on 60,000 lines of code. Over decades the community built confidence by pairing algorithmic output with rigorous verification tools, paving the way for today’s...

A Smartphone App Can Help Men Last Longer in Bed
A randomized 12‑week trial evaluated Melonga, a smartphone app that teaches pelvic‑floor, mindfulness and cognitive‑behavioural techniques to men with premature ejaculation. Among the 66 participants who completed the study, average intravaginal ejaculation latency rose from 61 seconds to 125 seconds,...

Parkinson's Disease May Reduce Enjoyment of Pleasant Smells
Scientists have found that people with Parkinson’s disease experience reduced enjoyment of pleasant odors such as lemon, indicating the world literally smells different for them. Loss of olfactory function affects 75‑90% of patients and often precedes motor symptoms by years,...

Sharing Genetic Risk Scores Can Unwittingly Reveal Secrets
Genetic risk scores, which condense millions of DNA variants into a single health probability, can be reverse‑engineered to approximate the underlying genotype. Researchers show that mathematical techniques using reference panels can reconstruct DNA from these scores, exposing private health information....

Frailty Sets in Far Earlier than You’d Expect, but You Can Reverse It
New research reveals frailty can begin decades before old age, with many people in their 30s and 40s already in a pre‑frail state. Around 10 % of those in their 50s show early signs, rising to about half of individuals in...

A Daily Multivitamin May Slightly Slow Rates of Ageing
Researchers conducted a double‑blind, placebo‑controlled trial with 1,000 participants averaging 70 years old, giving half a daily multivitamin (Centrum Silver) and the other half a placebo. After two years, analysis of five epigenetic aging clocks indicated the supplement group aged...

Inflammation Might Cause Alzheimer's – Here's How to Reduce It
Recent studies suggest that persistent inflammation in the gut, lungs and skin may trigger Alzheimer’s disease. Vaccinations such as Shingrix have been shown to cut dementia risk by about 17 percent, likely by dampening inflammatory pathways. Lifestyle measures—including a Mediterranean...

We Must Close the 'Shocking' Knowledge Gap in Women's Health
Anita Zaidi calls for urgent research to close the knowledge gap in women’s health, highlighting the deadly impact of pregnancy complications like pre‑eclampsia. More than 700 women and 6,500 newborns die daily from these conditions, with the highest toll in...
