Major discovery exposes immune system’s ‘off button’

Researchers have discovered the molecular mechanism that controls MR1, a protein responsible for alerting white blood cells to bacterial infections or cancer. By regulating MR1's activation, the immune response can be stimulated or inhibited, offering new potential for harnessing and controlling immunity.

Can robots have morals? Robots’ decisions on forced medication evoke doubts

A study at the University of Helsinki found that people accept human nurses overruling patient autonomy but reject similar decisions made by robots. The researchers suggest that human empathy is required to consider robot-made solutions equally acceptable as those made by humans. The findings imply that machines cannot comprehensively ...

New research throws doubt on old ideas of how hearing works

A study by researchers at Linköping University and the Oregon Health and Science University has discovered that many cells in the inner ear react simultaneously to low-frequency sound, making it easier to experience these sounds. This new understanding may lead to improved cochlear implants for people with severe hearing impairments.

Scientists reveal the different effects on storm tracks between the upper- and lower-level eddy growth over the North Pacific

Researchers find that midwinter suppression in the North Pacific is driven by differences in upper- and lower-level eddy growth properties. The study reveals that upper-level eddies are more complex, with growth suppressed during cold season, but near-jet exit can grow normally.

Ancient Maya cities were dangerously contaminated with mercury

Researchers discovered that ancient Maya cities in Mesoamerica were heavily polluted with mercury, contaminating the soil and water. The pollution was caused by the frequent use of mercury and cinnabar paints, powders, and other products, which leached into the environment and pose a potential health hazard today.

New Sub-Saharan Africa partnership expands 4R Nutrient Stewardship’s inclusive approach to agricultural transformation

The African Plant Nutrition Institute, Fertilizer Canada, and OCP Africa have signed a MoU to collaborate on agriculture development programmes that target sub-Saharan rural farmers. The planned interventions will see an improvement in food-security and livelihoods for smallholder farmers through joint programming, shared learning, and...

Strong link between gut bacteria and metabolites

A recent study published in Nature Communications has found a strong connection between the gut microbiome and certain blood metabolites. The research, led by Uppsala University, analyzed fecal and blood samples from over 8,500 participants in the SCAPIS study, identifying novel associations between gut bacteria and plasma metabolite s...

New advice for doctors on how to identify and respond to reproductive coercion

A new paper provides guidance for healthcare workers on recognizing signs of reproductive coercion, which can involve psychological pressure, emotional blackmail, and physical violence. Doctors are advised to ask specific questions and establish a professional relationship with patients to gather more information and provide support.

Will climate-change-driven temporal variation in precipitation affect crop yields and reactive nitrogen losses?

Temporal variation in precipitation caused by climate change negatively affects crop growth, leading to declining yields and increasing reactive nitrogen losses. The study found that adjusting fertilizer application amounts can reduce nitrogen losses, but may not increase crop yields.

Air pollution can amplify negative effects of climate change, new study finds

A new study finds that air pollution can worsen the social costs of carbon emissions, affecting human health, economies, and agriculture differently depending on where the pollutants are emitted. The research highlights how aerosol pollutants can increase climate change impacts by as much as 66% in some regions.

ExoClock counts down Ariel exoplanet targets

The ExoClock project, supported by European Space Agency's Ariel mission, has presented 450 candidate exoplanet target orbits and received contributions from 217 professional and amateur astronomers. Small telescopes can successfully observe most targets, highlighting the value of amateur community involvement in space research.

Acquired immunity against random food allergens may protect some lucky people against COVID-19

A recent study finds that exposure to proteins in common foods, vaccines, bacteria, and viruses can prime the immune system to attack SARS-CoV-2, potentially providing protection against COVID-19. The study's findings suggest that individuals with a history of exposure to these agents may be less susceptible to severe illness.

Transition to newer clot-busting drug improves patient outcomes, lowers cost in treating ischemic stroke

A new study found that the newer clot-busting drug tenecteplase outperforms traditional treatment for ischemic strokes in several key areas, including better health outcomes and lower costs. The shorter preparation and injection time with tenecteplase eliminated dosing errors and initiated transfers to advanced care sooner.

New UCI-led report illustrates potential of precision genome editing in treating inherited retinal diseases

Researchers at UCI have made significant progress in precision genome editing for treating inherited retinal diseases, enabling precise gene correction and disease rescue. The study highlights the potential of this technology to revolutionize treatment of genetic disorders of vision, with over 270 causative genes identified.

The plate boundary between Africa and the Iberian Peninsula could cause large tsunamis

A new study led by ICM-CSIC has revealed the complex geometry of the Alboran Sea faults system, which has been absorbing most of the deformation from plate collision. The research demonstrates that this region is one of the most important fault systems in the western Mediterranean and has a significant tsunami risk.

The rise to royalty; how worker wasps balance specialization and plasticity

Researchers investigated how paper wasps adapt their behavior when the queen is removed or dies, finding that they counterbalance genes that establish queen-like behavior with aggressive fighting. This enables societies to distinguish between intrinsic and extrinsic perturbations, allowing for plasticity in response to changes.

Watching the fate of molecular nitrogen with X-rays, when an electron has been kicked out

Researchers at the Max Born Institute have used novel ultrashort soft X-ray spectroscopy to study the fate of molecular nitrogen when an electron is kicked out. They found that the B state has a similar degree of excitation as the X state, contradicting previous models. Instead, a coherent interplay between light fields enables lasing ...
