Viruses help cut farm greenhouse gas emissions by targeting soil microbes

Researchers found that soil viruses selectively infect denitrifying microbes, reducing nitrous oxide emissions by up to 20%. The study suggests viral regulation as a potential method for mitigating greenhouse gas emissions in agriculture. Viruses may play a critical role in supporting sustainable food production and protecting the planet.

Countries with highest reported levels of hearing loss have lowest use of hearing aids

The study found that countries with the highest reported prevalence of hearing loss, such as China and South Korea, also had the lowest levels of hearing aid use. Conversely, adults in Northern Europe, USA, and Western Europe were most likely to report using a hearing aid. Men were generally more likely than women to report difficultie...

New approach to gravitational wave detection opens the Milli-Hz Frontier

Scientists have unveiled a new detector concept that uses optical cavity and atomic clock technologies to detect gravitational waves in the milli-Hertz frequency band. This approach provides an immediate, cost-effective means to explore the mid-band range, which hosts signals from compact binaries of white dwarfs and black hole mergers.

Early medical abortion at home up to 12 weeks is safe, effective, and comparable to hospital care

A study of 14,458 abortions in Scotland found that early medical abortion at home between 10-12 weeks of pregnancy is safe and effective, with a similar success rate to hospital procedures. However, women who had medical abortion at home were more likely to contact the abortion service for questions or concerns.

DFG to fund four new research units

The DFG is establishing four new Research Units to address pressing issues in linguistics, security, precision medicine and environmental history. The Research Units will focus on topics like bilingual flexibility, security in catastrophic times, genome-based precision medicine and medieval coastal landscape development.

Improvements in mental health best predict life satisfaction

A new study published in PLOS Global Public Health found that increases in mental health most strongly predict improvements in life satisfaction. The researchers used data from a weekly running event and found that even small improvements in mental health can lead to significant increases in life satisfaction.

ASTRO 2025 Highlights from MSK

Researchers at MSK presented two clinical trials looking at the benefits of lowering radiation doses for patients with throat cancer. The studies found that reducing treatment can protect the immune system and help patients recover quickly. Additionally, a trial on breast cancer treatment showed that accelerated partial breast irradiat...

New imaging system maps retinal oxygen in unprecedented detail

A new dual-imaging system simultaneously maps retinal structure and capillary oxygen levels in live mice, allowing researchers to study vision-threatening diseases like glaucoma and diabetic retinopathy. This non-invasive approach offers a powerful tool for elucidating local capillary values and tracking changes in retinal oxygenation.

New polymer designs for beyond-5G telecommunications

Researchers at Waseda University have developed a new class of polymers with ultralow dielectric loss, enabling high-speed telecommunications. The polymers, specifically poly(2,6-dimethyl-1,4-phenylene sulfide) (PMPS), achieved a low dielectric constant and dissipation factor, making them suitable for future 5G and beyond networks.
