NICE backs four-year NHS evaluation of donated-lung perfusion system

NICE has issued draft guidance recommending a four-year NHS evaluation of the XVIVO perfusion system for donated lungs. The system keeps lungs functioning outside the body so teams can monitor them and, in some cases, treat infection, remove fluid or reinflate collapsed areas before deciding on transplantation. NICE estimates it could help recover four in five donated lungs that are currently unused, though the estimate and value for money require evaluation.

Mandarin learners use different cues for different English vowel contrasts

A Taiwan-led study reports that Mandarin-speaking learners of English used different cues to distinguish two English vowel contrasts: chiefly duration for beat–bit and chiefly vowel quality for bat–bet. Those listening patterns were selectively associated with clearer production of the corresponding cue during imitation. The findings, published in Second Language Research, indicate that first-language sound categories can shape both how unfamiliar speech is heard and how it is reproduced.

Thailand team prepares biodegradable 3D-printed pods for seagrass trials

Murdoch University and Walailak University are developing 3D-printed, biodegradable PHA pods to protect transplanted seagrass at Koh Lidi in Thailand’s Mu Ko Phetra National Park. The dome-and-anchor prototype is designed to shield shoots from waves, moving sediment and grazing animals while roots establish, then biodegrade. The pods are still undergoing safety and packaging testing before field trials.

Sonar and underwater cameras confirm living coral communities off Benin

Researchers surveying seabed off Benin have documented a living, patchy mesophotic coral ecosystem more than 50 metres deep, at a site regarded as probably dead in 1960s surveys. Sonar identified likely reef signatures across an 11.5-kilometre survey, and underwater cameras showed corals on rocky areas and fish using the habitat. Direct coral samples have not yet been collected, so species identifications and the reef’s wider extent remain unresolved.

Ecuadorean Laron syndrome study examines clues to lower cancer rates

Researchers studying people with Laron syndrome in southern Ecuador are investigating why cancer and diabetes were less frequently observed in a long-running cohort than among normal-height relatives from the same villages. The work focuses on disrupted growth-hormone signalling and low IGF-1, but researchers say more study is needed before any treatment can be developed. The report also documents limited access to IGF-1 therapy for children with the rare condition.

Oxford trial links eight weeks of salsa classes to lower depression and social anxiety symptoms

A reported randomised controlled trial involving 121 young adults found that an eight-week salsa programme was associated with greater reductions in depressive symptoms and social anxiety than a control group. Participants aged 18 to 24 also reported larger increases in daily happiness, but researchers said salsa is not yet supported as a stand-alone treatment for clinically diagnosed depression.

Mica-based method aims to keep atom-thin material stacks cleaner

Researchers at the University of Southampton and the National University of Singapore report a polymer-free way to assemble atomically thin 2D material stacks using muscovite mica. They say the approach produces atomically flat, cleaner surfaces and enables more precise alignment of layers. The findings were published in Nature Communications and may aid research on quantum materials and nanoelectronics.

Wild koalas begin trial of biodegradable chlamydia vaccine booster implant

A wild koala in Burleigh, Queensland, has received a biodegradable implant designed to deliver the booster dose of a two-dose chlamydia vaccine about 30 days after the first injection. The report says five wild koalas have now received implants, with monitoring planned for at least six months. The approach is intended to remove the need to recapture animals for a booster, though effectiveness in wild populations remains under evaluation.

Stationary device reproduces a black-hole-inspired wave-amplification effect

Researchers at the Advanced Science Research Center at the CUNY Graduate Center report a stationary radio-frequency device that reproduced a wave-amplification effect inspired by theories of energy extraction from rotating black holes. A synchronized sequence of changes in a ring of electronic resonators created synthetic rotation, allowing selected electromagnetic waves to gain energy from the engineered modulation. The work, reported in Nature, is a laboratory analogue rather than energy extraction from a real black hole.

Largest viral-protein library gives researchers new way to probe emerging pathogens

A new viral ORFeome library, the largest of its kind, allows researchers to analyze thousands of viral proteins simultaneously. This innovative tool enhances the understanding of how viruses manipulate human cells, potentially accelerating the development of vaccines and treatments. By broadening access to virology research, it empowers scientists to explore previously unstudied viruses and their interactions with host cells.

NHS drugs go-ahead offers lifeline to children with rare muscle-wasting disease

The NHS has approved two treatments for spinal muscular atrophy (SMA), providing hope for hundreds of affected children. The National Institute for Health and Care Excellence (NICE) has recommended nusinersen and risdiplam, allowing patients in England, Wales, and Northern Ireland to access these life-changing therapies. Parents express relief and gratitude, as these drugs can significantly improve survival and quality of life for their children.

Neanderthal Dentists: Evidence of Ancient Dental Care

A recent study reveals that Neanderthals used stone drills to treat cavities nearly 60,000 years ago, showcasing their advanced dental practices. The findings, based on a molar from Chagyrskaya Cave, indicate that Neanderthals could identify dental issues and perform procedures to alleviate pain. This discovery highlights the sophistication of Neanderthal medical knowledge and skills.
