Retrieving physical properties from two-colour laser experiments

Physicists have discovered that useful information about ultrafast light-matter interactions is buried deep within signals produced by two-colour pump-probe experiments. Advanced techniques are required to extract this information, which could lead to breakthroughs in fields such as vision and photosynthesis.

Detection of oral HPV DNA in teen, young adult females

Researchers detected oral HPV DNA in 6.2% of teen and young adult female participants, with detection decreasing over time since becoming sexually active. The study suggests that the HPV vaccine is less effective against certain types of oral HPV in vaccinated individuals compared to those who are fully unvaccinated.

Experts in high-risk pregnancy respond to the published results of the PROLONG trial

The PROLONG trial found that weekly injections of 17-alpha-hydroxyprogesterone caproate do not reduce recurrent preterm birth or neonatal morbidity. In contrast, a previous study showed a 34% reduction in recurrent preterm birth with this medication. The differing results may be attributed to differences in the populations studied.

Researchers identify improved avenues to train plastic surgeons in microsurgery

Researchers at McGill University have identified improved avenues for training plastic surgeons in microsurgery. By adopting non-biological simulators, they found a 48% decrease in the number of animals needed for training and a 50% reduction in costs. This shift also reduces animal use, death, and improves performance on animal models.

Novel formulation of an injectable drug to treat joint inflammation acts for ten days

Researchers developed an injectable drug formulation using lipid nanoparticles to sustain the effect of naproxen in treating temporomandibular joint inflammation. The study showed significant reduction in inflammation and absence of side effects, making it a potential treatment option for this condition.

Nerve cell protection free from side effects

Scientists at the University of Göttingen have identified an alternative erythropoietin receptor, CRLF3, which triggers protective effects in humans without stimulating red blood cell production. This discovery offers new hope for treating neurodegenerative diseases such as Alzheimer's and Parkinson's.

Stanford study casts doubt on carbon capture

A Stanford University study published in Energy and Environmental Science suggests that carbon capture technologies can cause more harm than good, reducing only a small fraction of carbon emissions. The research concludes that using renewable energy options like wind or solar is always better from a social cost perspective.

Birds do not habituate to traffic noise

Researchers found that birds in constant traffic noise had lower levels of corticosterone in their blood compared to quiet environments. This suppression may protect against negative effects of chronic stress on the immune system. Chicks from noisy parents were also smaller but caught up after leaving the nest.

A tale of two cities: Impact of reducing teens' access to flavored tobacco products

A new study found that enforcing restrictions on flavored tobacco products led to decreased teen use of both flavored and non-flavored tobacco. In contrast, a nearby community without such restrictions saw an increase in tobacco use among youth. The study suggests that flavor restriction policies can curb youth tobacco use in as little...

Babies understand counting years earlier than believed

Researchers at Johns Hopkins University discovered that babies can recognize counting as a way to describe quantity, even before they can verbally express the numbers. The study found that when toys were counted aloud, babies showed an understanding of the approximate number and expected more than one toy to be pulled from the box.
