Hollow optical fibers for UV light

Researchers have developed a new type of optical fiber that can guide UV laser light without being damaged. The fiber has a hollow core with a diameter of 20 µm, which allows for single-mode transmission and reduces loss. This breakthrough enables new applications in precision spectroscopy, fluorescence microscopy, and process plasmas.

New approach for tuberculosis drugs

Researchers at ETH Zurich have developed a new approach for tuberculosis drugs, inspired by the bacteria-derived antibiotic pyridomycin. The new molecule is more stable and easier to produce synthetically, offering a potential solution to multidrug-resistant strains.

Reinterpreting dark matter

New research opens up possibility that dark matter governs structure across whole universe, resolving puzzles in galaxy cores and formation timing. The theory suggests large stationary waves of dark matter called solitons could explain observed phenomena.

Superconducting-silicon qubits

Theorists propose using a bottom-up approach to create hybrid quantum devices by placing superconducting regions within silicon crystals. This could combine the benefits of both silicon spin qubits and superconducting circuits, enabling more robust qubit designs.

The Lancet: Largest study to date finds insulin pumps result in better blood sugar control than multiple daily injections in people with type 2 diabetes

The OpT2mise trial found that insulin pumps result in better blood sugar control than multiple daily injections in people with type 2 diabetes. The study showed that patients using the pumps achieved a significantly greater reduction in average blood sugar levels and spent less time in hyperglycaemia.

Genetic study reveals vulnerability of northwest dolphins

A recent genetic study found that northwest dolphins in Australia are more vulnerable to environmental change and localised extinctions due to their isolated populations. The researchers urge management agencies to preserve corridors for individuals to travel between populations.

Veterans with muscle injuries and mental health conditions more likely to end service

A new study from Michigan Medicine found that 60% of U.S. Army soldiers who couldn't return to a military career after an Iraq deployment had a muscle, bone or joint injury and nearly half had a mental health diagnosis. The strongest predictors of inability to continue serving were musculoskeletal conditions, psychological diagnoses, a...

Hypertension, antihypertension medication, risk of psoriasis

A study published in JAMA Dermatology found that women with long-term hypertension are at a higher risk of developing psoriasis. Long-term use of beta-blocker medication also increases the risk of psoriasis. The study analyzed data from 77,728 women and found a significant association between hypertension and psoriasis risk.

New compound blocks 'gatekeeper' enzyme to kill malaria

Researchers at the Walter and Eliza Hall Institute have developed a compound that blocks Plasmepsin V, a critical enzyme essential for malaria parasite survival. The compound, WEHI-916, has shown promising results in killing malaria parasites and could lead to effective treatment of all species of the parasite.

Short sleep, aging brain

Researchers at Duke-NUS found that short sleep is linked to faster brain ventricle enlargement and decline in cognitive performance. The study of 66 older Chinese adults suggests that seven hours of sleep per day may be optimal for brain health.

Weekend emergency surgeries deadlier for children

A study published by Johns Hopkins Medicine found that children undergoing simple emergency surgeries on weekends are more likely to suffer complications and die than those treated during the week. The researchers analyzed 22 years' worth of surgical records involving nearly 440,000 pediatric admissions nationwide.

Solar panels light the way from carbon dioxide to fuel

Researchers at Princeton University have developed an efficient method for harnessing sunlight to convert carbon dioxide into formic acid, a potential alternative fuel. The process achieves nearly 2% energy efficiency, twice that of natural photosynthesis, and has the potential to store solar energy in fuel cells.
