Researchers at Karolinska Institutet have created a new method of studying the smallest bioparticles in the body. The study, which is published in Nature Biotechnology, has considerable scientific potential, such as in the development of more effective vaccines.

Studies show that consumers believe people who work hard for their money have higher incomes, are more financially literate and are more comfortable taking on prudent financial risk.

A new instrument for studying a web of filaments that connects galaxies across the universe has captured its first image, a milestone known in astronomy as "first light." The Keck Cosmic Reionization Mapper (KCRM) at the W.M. Keck Observatory atop Maunakea summit in Hawaiʻi, will provide detailed maps of gas around dying stars and other cosmic objects, and it will map the so-called cosmic web...

Recent research has revealed which bird species are the most pleasant to the human eye, and which are less attractive. The most visually appealing species were often colorful birds, but also some large birds of prey are in the top.

The globally-agreed mission to curtail climate change will be impossible unless governments, authorities and the largest companies urgently strengthen their targets, according to the 2023 Net Zero Stocktake report today from an international team, including Oxford researchers and students.

Public confidence in vaccines has declined across sub-Saharan Africa since the COVID-19 pandemic, new research shows. A survey of 17,000 people in eight African nations found that the share of respondents agreeing with the statement that “vaccines are important for children” dropped by up to 20 percentage points from 2020 to 2022. The survey also revealed growing doubts about...

As the world struggles for sustainability in the face of climate change, wildfire smoke becomes a lesson in how people can become victims far from the root of a problem and far from their control.

Products made from polymers—ranging from plastic bags to clothing to cookware to electronics—provide many comforts and support today's standard of living, but since they do not decompose easily, they pose long-term environmental challenges. Developing polymers, a large class of materials, with a more sustainable life cycle is a critical step in making progress toward a green economy and...

The Arctic Ocean is connected with the Pacific and the Atlantic Oceans through several ocean gateways, and changes in the linkage between these oceans and the Arctic Ocean can affect both climate and marine ecosystems.

Social network companies use a variety of methods, such as a friend recommendation, to increase connectedness and user engagement within the network, but how each company does so effectively is not widely known.

Malaria was common in Renaissance Italy. The disease was known as "Febbre terzana" at the time as an onset of the fever occurred in intervals of two to three days. A research team led by Eurac Research has now microscopically detected the parasite Plasmodium falciparum, the causative agent of the dangerous malaria tropica in soft tissue from embalming vessels found at the Basilica di San Lorenzo...

American consumers use their understanding of gun rights when judging the morality of civilians' use of guns to protect themselves from crime, and that assessment varies depending on specific scenarios, new research from Oregon State University shows.

Police investigations use wiretapped phone recordings as investigative material fairly regularly. But how do they know that the voice on the recording actually belongs to the suspect? Ph.D. student Laura Smorenburg is trying to answer that question.

Filipino scientists have developed a low-cost method of sterilizing ballast water to help prevent the risk of spreading potentially invasive species from port to port.

Despite decades of warnings and international climate agreements, global carbon emissions are still rising. Carbon emissions seem like an unstoppable juggernaut as energy-hungry humans keep breeding and pursuing more affluent lifestyles. Reducing emissions won't be enough to confront the climate crisis; we need additional solutions.

Aluminum-ion batteries are seen as a promising alternative to conventional batteries that use scarce and difficult-to-recycle raw materials such as lithium. This is because aluminum is one of the most common elements in the Earth's crust, is easier to recycle and is also safer and less expensive than lithium. However, the development of such aluminum-ion batteries is still in its infancy, as...

COVID-19, invasive species, and the spread of persistent chemicals and plastics provide one form of evidence that we live on a planet with an interconnected biosphere. Dangers from one part of the planet find their way to other parts of the planet. Our oceans and atmosphere, along with ships and jet planes, transport pollutants around the globe.

From water temperature to the regional hydrological cycle: the working group Dynamics of Regional Climate Systems at the Leibniz Institute for Baltic Sea Research Warnemünde has recently succeeded, with the help of regional climate models and the statistical analysis of long-term observations, in identifying a strong influence of the Atlantic on the Baltic Sea region behind the signal of climate...

Scientists from the University of Ottawa and the Max Planck Institute for the Science of Light are proposing a breakthrough approach that will facilitate discoveries in materials science by combining terahertz (THz) spectroscopy and real-time monitoring.

Our genomic DNA is continuously damaged by endogenous factors such as reactive oxygen species, and also by environmental factors such as ultraviolet light, radiation, and chemicals. Failure to repair damaged DNA may induce mutations and cell death, eventually leading to the onset of cancer and other diseases. To prevent this, our cells are equipped with various defense systems aimed at finding and...

In the world of optics, capturing high-dimensional optical information is crucial for understanding and characterizing various targets across different scenes. This includes important aspects like irradiance, spectrum, space, polarization, and phase. However, finding a single system that can gather all this information efficiently—while also being lightweight, portable and cost-effective—is...

A national study has found cyclists who wear safety vests or helmets look 'less human' compared to cyclists who do not.

A new study led by CABI has confirmed that the samurai wasp (Trissolcus japonicus)—a natural enemy of the brown marmorated stink bug (Halyomorpha halys) pest—has minimal impact on native stink bugs.
