Gold nanoantennas help in creation of more powerful nanoelectronics

Scientists used gold nanoparticles with molybdenum disulfide to study strain occurring when a semiconductor contacts a conductor at the nanoscale. They demonstrated localized strain of 1.4% using Tip-Enhanced Raman Spectroscopy, a unique technology that combines optical and atomic force microscopy.

Vanderbilt study shows azithromycin overprescribed for childhood pneumonia

A recent Vanderbilt University Medical Center study found that combination therapy with azithromycin is unnecessary in most cases of pediatric pneumonia. The study of 1418 children showed no significant differences in outcomes between patients treated with a single antibiotic versus a combination of antibiotics. The researchers argue t...

Researchers look for dawn of human information sharing

A team of researchers, led by Luke Premo, question the widely accepted timeline of human cultural transmission, suggesting that it may be much more recent. They propose that the Oldowan tool, believed to be one of the first stone tools made by humans, could have been learned through innate skill rather than cultural transmission.

Ensuring the survival of elephants in Laos: A matter of economics

The study found that Laos' elephant population, which has dropped by half in the last 30 years, depends heavily on socio-economic practices. Implementing a 'maternity-leave' system for owners could help offset losses and promote breeding, potentially saving the species.

Time to rewrite the dinosaur textbooks? Not quite yet!

A recent proposal to reorganize the traditional dinosaur family tree has sparked debate among experts. However, a new analysis by an international consortium found that the current model of an Ornithischia-Saurischia split remains supported, albeit with weak evidence for an alternative arrangement.

Breast cancer patients forego post-surgery treatment due to mistrust, study suggests

A large survey of breast cancer patients found that nearly one-third went against their doctor's advice and chose not to complete recommended adjuvant anti-cancer therapy. Patients with higher distrust in the healthcare system were more likely to report noncompliance, highlighting the need for strategies beyond boosting physician trust.

Investigating the collateral effects of antibiotics

A new study found that most antibiotics decrease bacterial motility in multidrug-resistant Salmonella, but kanamycin increased swarming in one strain. Researchers hope to identify the accessory genes responsible for this effect to inform antibiotic choice.

New analysis shows Brazil slows deforestation with land registration program

A new study by Oregon State University shows that Brazil's environmental land registration program has slowed down deforestation on private land, particularly in the Amazon region. The CAR (Cadastro Ambiental Rural) system allows landowners to demonstrate compliance with regulations and provides a mechanism for government monitoring.

Saliva proteins could explain why some people overuse salt

A study found that people who can easily taste salt have differing amounts of salivary proteins than those who are less sensitive. This could lead to the development of more palatable low-sodium foods.
