Anticoagulant treatments are crucial for managing many conditions, such as heart disease, stroke and venous thrombosis. Current options, however, carry an inherent risk of serious bleeding due to trauma or unforeseen events. A team from the University of Geneva (UNIGE) and the University of Sydney has developed a new anticoagulant, designed to have an on-demand reversible activity, with a fast-acting "antidote."

According to a recent study published in Nature Geoscience, scientists have found that soil carbon dioxide (CO2) emissions are more sensitive to climate warming in permafrost-collapsed areas than in non-collapsed areas.

Papua New Guinea (PNG) has a wide range of environments, each presenting unique challenges to human survival. Highlanders and lowlanders of PNG are striking examples of populations facing distinct environmental stress. Whereas the highlanders encounter low oxygen availability due to altitude, the lowlanders are exposed to specific pathogens that are absent in the highlands, such as malaria. Despite these strong environmental pressures, the specific adaptations of these populations have remained overlooked.

California's state fossil—are familiar to anyone who has ever visited Los Angeles' La Brea Tar Pits, a sticky trap from which more than 2,000 saber-toothed cat skulls have been excavated over more than a century.

A team led by Purdue University soybean geneticist Jianxin Ma has developed a new biotechnological tool for the domestication of desirable traits from wild soybeans, such as resistance to leafhopper insect pests. The use of such tools, called de novo domestication, makes it easier for scientists to engineer crop improvements from wild soybeans.

It is well known that getting plenty of exercise and mental training are important for a long and healthy life. But which is more effective? Do the tasks develop abilities that go beyond them?

In recent years, electro-conductive composite ceramics have gradually become a research hotspot in the functionalization of structural ceramics. However, the improvement of conductivity is generally achieved at the cost of increasing the content of conductive phases or sacrificing the mechanical properties of the composite ceramics.

A study by researchers from the Ecology area of the Miguel Hernández University of Elche (UMH) and the Ecology department of the University of Alicante (UA) reveals the fundamental importance of scavengers and carrion in wetlands.

New research presented at this year's European Congress of Clinical Microbiology and Infectious Diseases (ESCMID 2024, Barcelona 27-30 April) shows that levels of resistance to antimicrobials (AMR) varies with age and sex, with age in particular showing substantial variation both between and within countries. The study by Gwen Knight, Associate Professor at the London School of Hygiene and Tropical Medicine and co-Director of the LSHTM AMR Centre, London, UK, and colleagues, is published in PLOS Medicine.

The return of spring in the Northern Hemisphere touches off tornado season. A tornado's twisting funnel of dust and debris seems an unmistakable sight. But that sight can be obscured to radar, the tool of meteorologists. It's hard to know exactly when a tornado has formed, or even why.

What do the flow of cars on a highway and the movement of bacteria towards a food source have in common? In both cases, annoying traffic jams can form. Especially for cars, we might want to understand how to avoid them, but perhaps we've never thought of turning to statistical physics.

A new study from the Tepper School of Business at Carnegie Mellon University published in the Journal of Business and Technical Communication shows that ChatGPT can help students create effective visualizations, but is not as helpful in providing data analysis.

As the impacts of climate change increasingly affect the daily lives of residents in several countries, including Brazil, the resilience of forests, especially tropical ones such as the Amazon, has become a frequent topic of research. In addition to studying various factors that influence the way vegetation reacts to global warming, scientists are seeking to improve vegetation models—tools that play a crucial role in understanding and managing ecosystems, contributing to biodiversity conservation and sustainable development.

Eighty percent of climatic migrants are women and children. This figure means that a new international legal framework is required to protect human rights by adding gender-sensitive measures to policies and legislation. This is the claim made by Susana Borràs, a researcher from the University of Rovira's Department of Public Law in an article published in the journal Environmental Policy and Law, in which she discusses the complexities of perpetuating inequalities, vulnerabilities and the lack of protection of migrant women and children.

A recent study conducted by the research team at Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has introduced a new method for enhancing X-ray detection by incorporating out-of-phase CsPb2Br5 perovskite into CsPbBr3 bulk material.

Researchers at the University Hospital Bonn (UKB), the University of Bonn, and the German Center for Infection Research (DZIF) have discovered a new lantibiotic, namely epilancin A37. It is produced by staphylococci that colonize the skin and act specifically against their main competitor there, the corynebacteria.
