Starwatch: Ophiuchus the serpent bearer, straddling the celestial equator

Spot this large constellation with differing classical backstories as moon sits squarely in ‘teapot’ of SagittariusThis week we will look for another large but faint constellation: Ophiuchus, the serpent bearer. One of the original 48 constellations listed by Ptolemy in the 2nd century, it sits in the sky on the opposite side to Orion, the hunter. The chart shows the view looking south from London at 11pm BST on 29 June 2026.Although the view will remain essentially unchanged all week, on this p

These fat-filled brain cells may be making multiple sclerosis worse

Scientists have uncovered a surprising clue that may help explain why multiple sclerosis (MS) progresses rapidly in some people but not others. In brain tissue from patients with severe MS, researchers found large numbers of “foamy” immune cells packed with fat droplets after absorbing damaged myelin. These overloaded cells appear to switch from helping repair the brain to fueling ongoing damage and inflammation.

Brain activity under anesthesia challenges what we know about consciousness

The unconscious brain appears to be far more capable than scientists once believed. Researchers found that patients under general anesthesia could still process language at a sophisticated level, distinguishing nouns, verbs, and adjectives while listening to stories. Even more remarkably, neural activity showed signs of predicting upcoming words before they were heard. The results challenge traditional ideas about consciousness and hint at new possibilities for brain-computer interfaces.

These tiny soil microbes could rescue crops from salty farmland

Researchers have discovered that beneficial soil bacteria give plants an unexpected survival advantage in salty soils. Instead of helping plants keep salt out, the microbes stimulate the production of lignin, a natural compound that strengthens roots and makes plants more resilient. Greenhouse and field tests showed healthier plants and higher yields in salty conditions. The findings could lead to bio-based treatments that help farmers grow crops on land once considered too salty for agriculture

Only one workout helped older adults lose fat without losing muscle

A six-month study of more than 120 adults in their 70s found that high-intensity interval training (HIIT) may offer a key advantage over other forms of exercise: it helped reduce body fat while preserving valuable muscle mass. While moderate and low-intensity workouts also led to some fat loss, only HIIT maintained lean muscle, which becomes increasingly important with age.

James Webb uncovers exotic salt clouds on a mysterious pink world

Astronomers have finally cracked the mystery of the famous “Pink Planet,” a strange world 57 light-years away that has puzzled scientists for more than a decade. Using the James Webb Space Telescope, researchers discovered that its atmosphere contains water vapor, methane, carbon dioxide, ammonia, and something never directly confirmed before in such an object: salty clouds.

Common pesticide linked to more than double the risk of Parkinson’s disease

Scientists at UCLA have linked long-term exposure to the pesticide chlorpyrifos with a sharply increased risk of Parkinson’s disease. People exposed to the chemical near their homes were more than twice as likely to develop the condition. Laboratory studies showed that chlorpyrifos damages dopamine neurons and interferes with the brain’s ability to remove toxic protein buildup.

What if doing more isn’t always the answer?

It’s tempting to treat overwhelm with clever fixes – but that might be part of the problemAccording to my Instagram feed, I am not doing enough.

Hawaii is turning ocean plastic and fishing nets into roads

Hawaii researchers are giving old fishing nets and recycled plastic a second life by mixing them into asphalt roads. Early tests found these roads didn't release more plastic particles than standard pavement, with tire wear overwhelming any plastic signal from the recycled material. If future studies confirm the roads are durable, the technology could help tackle both marine pollution and overflowing landfills.

Massive study links teen marijuana use to double the risk of serious mental illness

Teens who use cannabis may face a substantially greater risk of developing serious mental health conditions, including psychotic and bipolar disorders, according to a study of more than 463,000 adolescents. Researchers found cannabis use often preceded these diagnoses by nearly two years, strengthening concerns about its long-term effects on developing brains.

Yellowstone’s supervolcano may be fueled by something unexpected

Scientists have uncovered a new explanation for what powers Yellowstone and other supervolcanoes. Instead of a deep plume rising from near Earth’s core, a broad “mantle wind” may push hot rock beneath Yellowstone, generating magma closer to the surface. This process helps create a massive underground magma network and may explain how supervolcanoes remain active for long periods.

Mountain lions changed everything in this tiny California preserve

A surprising ecological makeover unfolded when mountain lions began frequenting a small preserve south of San Francisco. Deer activity dropped, plants recovered, and shifts among predators like coyotes, bobcats, and foxes followed. The study shows that powerful “trophic cascades” aren’t limited to remote wilderness—they can happen in small, suburban preserves too.

New vitamin B12 therapy shows promise against deadly brain cancer

Researchers have identified a vitamin B12–based compound that can cross the blood-brain barrier and home in on glioblastoma tumors. In animal studies, the compound accumulated preferentially in tumor tissue and delivered sustained nitric oxide directly to cancer cells. It also worked synergistically with existing glioblastoma treatments, significantly enhancing their tumor-fighting effects.

Scientists stunned by signs of ancient life in a place no one expected

Scientists exploring ancient seafloor rocks in Morocco discovered mysterious wrinkle patterns where they were never expected to occur. These structures are normally linked to microbial mats in shallow, sunlit waters, yet the rocks formed hundreds of feet below the surface in darkness. Evidence indicates that chemosynthetic microbes created the wrinkles, revealing that deep-ocean microbial ecosystems may have been more widespread than previously thought.
