In the fight against bacterial pathogens, researchers are combining vaccination with targeted colonization of the intestine by harmless microorganisms. This approach could potentially mark a turning point in the antibiotics crisis.

Drastic declines in biodiversity due to human activities present risks to understanding animal behaviors such as tool use, according to new research. Shrinking animal populations make the study of these behaviors increasingly difficult, underscoring the urgency of targeted conservation efforts and inclusive conservation strategies. Action is needed not only for research, but also to respect our shared cultural heritage with animal species.

Researchers have developed a method that shows how the nervous system and sensory organs are formed in an embryo. By labeling stem cells with a genetic 'barcode', they have been able to follow the cells' developmental journey and discover how the inner ear is formed in mice. The discovery could provide important insights for future treatment of hearing loss.

Scientists have helped to construct a detailed timeline for bacterial evolution, suggesting some bacteria used oxygen long before evolving the ability to produce it through photosynthesis.

A switch of just two weeks from a traditional African diet to a Western diet causes inflammation, reduces the immune response to pathogens, and activates processes associated with lifestyle diseases. Conversely, an African diet rich in vegetables, fiber, and fermented foods has positive effects. This study highlights the significant impact of diet on the immune system and metabolism.

A solar wind event from 2017 that hit Jupiter and compressed its magnetosphere created a hot region spanning half Jupiter's circumference.

The same dirt that clings to astronauts' boots may one day keep their lights on. Researchers created solar cells made out of simulated Moon dust. The cells convert sunlight into energy efficiently, withstand radiation damage, and mitigate the need for transporting heavy materials into space, offering a potential solution to one of space exploration's biggest challenges: reliable energy sources.

A new study has found that the world's finest yodellers aren't from Austria or Switzerland, but the rainforests of Latin America. The research provides significant new insights into the diverse vocal sounds of non-human primates, and reveals for the first time how certain calls are produced. The researchers have discovered that special anatomical structures called vocal membranes allow monkeys to introduce 'voice breaks' to their calls. These have the same rapid transitions in frequency heard in Alpine yodelling, or in Tarzan's famous yell, but cover a much wider frequency range.

An international team has merged two lab-synthesized materials into a synthetic quantum structure once thought impossible to exist and produced an exotic structure expected to provide insights that could lead to new materials at the core of quantum computing.

Researchers have successfully developed a novel drug to restore vision. The treatment method restores vision through retinal nerve regeneration.

For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe. The James Webb space telescope now reveals that galaxies stopped forming stars earlier than expected. A recent discovery deepens the tension between theoretical models of cosmic evolution and actual observations. Among hundreds of spectra obtained with the Webb program RUBIES, the team has found a record-breaking galaxy that had already stopped forming stars during an epoch where galaxies are normally growing very rapidly.

Using a mathematical model, researchers have shed new light on the transition from hunter-gatherer to farming societies. Rather than focusing exclusively on external factors, they looked at internal demographics and the significant impact of human interactions. The model identified potential societal outcomes based on demographic changes, emphasizing aspects such as migration rates, cultural assimilation and the role of mortality in these transitions. The researchers aim to further develop their model with the aim of making it a standard tool for studying historical demographic interactions.

A 'weekend warrior' approach to physical activity -- getting 150 minutes of moderate-to-vigorous physical activity over one to two days instead of throughout the week -- improved health and lowered the risk of death, finds a new stud.

An international team is currently closely tracking the near-Earth asteroid 2024 YR4. The impact probability estimates for the year 2032 has been reduced from a peak of 3 percent to below 0.001 percent.

Researchers have demonstrated how specific biomarkers in the blood can predict the development of dementia up to ten years before diagnosis, among older adults living independently in the community.

In new images, scientists have gotten the closest look yet at Sagittarius C -- a 'stellar nursery' where clouds of gas and dust have collapsed to form thousands of new stars.

Smaller than a grain of rice, new pacemaker is particularly suited to the small, fragile hearts of newborn babies with congenital heart defects. Tiny pacemaker is paired with a small, soft, flexible wearable patch that sits on the patient's chest. The wearable patch detects irregular heartbeats and automatically emits pulses of light. The light then flashes on and off at a rate that corresponds to the correct pacing. After the tiny pacemaker is no longer needed, it dissolves inside the body.

A new analysis of a vaccination program in Wales found that the shingles vaccine appeared to lower new dementia diagnoses by 20% -- more than any other known intervention.

An international team has sequenced the first ancient genomes from the so-called Green Sahara, a period when the largest desert in the world temporarily turned into a humid savanna-like environment. By analyzing the DNA of two 7,000-year-old naturally mummified individuals excavated in the Takarkori rock shelter in southwestern Libya, the team showed that they belonged to a long-isolated and now extinct North African human lineage.

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics.

Researchers interrogated the 'sounds' of a cluster of stars within the Milky Way, uncovering a new technique for astrophysicists to probe the universe and learn more about its evolution.

A newly published study found that a mother's exposure to phthalates during pregnancy can affect their newborn's metabolism and brain development. These widely used plasticizers are commonly found in a variety of cosmetics and personal care products, such as shampoos, soaps, and detergents, as well as plastic food and beverage containers.

More mammals were living on the ground several million years before the mass extinction event that wiped out the dinosaurs, new research has revealed.

New projections reveal a 4 degree Celsius rise in global temperatures would cut world GDP by around 40% by 2100 -- a stark increase from previous estimates of around 11%.

While the threat that microplastics pose to human and ecological health has been richly documented and is well known, nanoplastics, which are smaller than one micrometer (1/50th the thickness of an average human hair), are far more reactive, far more mobile and vastly more capable of crossing biological membranes. Yet, because they are so tiny and so mobile, researchers don't yet have an accurate understanding of just how toxic these particles are.
