Working hard for money decreases consumers' willingness to risk their earnings, study shows
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.
New observatory instrument sets its sights on Turtle Nebula
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.
People's choice: Snowy owl and kingfisher triumph as Finland's most attractive birds
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...
Report: Net zero targets must become a reality to keep Paris temperature goals live
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.
In Africa, doubts about vaccines grew during pandemic, survey finds
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.
Where there's smoke, there are lessons in demands of global sustainability
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...
Advancing material innovation to address the polymer waste crisis
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.
Climate change is altering the linkage between the Arctic and subarctic oceans, finds study
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...
Study explores how social network users decide to make friends
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.
Microscopic evidence of malaria in the Medici era
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.
U.S. consumers judge morality of armed self-protection on case-by-case basis, research shows
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...
Lips pouted or not? How improved speaker recognition can help forensic investigations
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.
Scientists develop cheaper method to sterilize ballast water
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.
Opinion: Geoengineering is shockingly inexpensive
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.
Team develops organic redox polymer for aluminum-ion batteries with improved storage capacity
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.
Opinion: The fire this time—facing the reality of climate change
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...
The Baltic sea climate under the influence of the Atlantic: New findings on a 'long distance relationship'
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.
Unveiling the invisible: A breakthrough in spectroscopy to allow discoveries in materials physics
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...
New insight into how xeroderma pigmentosum causative gene products ensure the accuracy of DNA repair
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.
Spectropolarimetric imaging: A magical way to get multidimensional information
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...
Cyclists with more safety attire seen as 'less than fully human,' finds Australian study
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...
Samurai wasp has minimal impact on native stink bugs, new study confirms
A national study has found cyclists who wear safety vests or helmets look 'less human' compared to cyclists who do not.
Study: Rising rainfall, not temperatures, threaten giraffe survival
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.
Giraffes in the East African savannahs are adapting surprisingly well to the rising temperatures caused by climate change. However, they are threatened by increasingly heavy rainfall, as researchers from the University of Zurich and Pennsylvania State University have shown.
