A low level of atmospheric oxygen in Earth’s middle ages held back evolution for two billion years, raising fresh questions about the origins of life on this planet.
New research by the University of Exeter explains how oxygen was trapped at such low levels. (more…)
Now that scientists understand what triggers key steps in the immune response to menacing fungi such as Candida albicans, they hope to develop ways to make it work better.
PROVIDENCE, R.I. [Brown University] — Every year, fungal infections threaten thousands of patients — from those with depressed immune systems to others who have had surgeries or devices such as catheters implanted. Moreover, some anti-fungal medications are beginning to lose their power. (more…)
Berkeley Lab researcher tackling common questions that cut across the field of nuclear science
Nuclear science, a field focused on what’s at work in the center of atoms, brought us a powerful energy source and new medical treatments and imaging tools. (more…)
Simulationen der DIW-EnergieökonomInnen zeigen: Werden die deutschen Klimaschutzziele eingehalten, braucht es keine Braunkohletagebauerweiterungen – Höhe und Insolvenzsicherheit der Rückstellungen für Rekultivierung unsicher – Braunkohleausstieg sollte frühzeitig und sozialverträglich geplant werden. (more…)
Researchers from North Carolina State University and the National Institutes of Health (NIH) have developed a method that stops allergic reactions by removing a key receptor from mast cells and basophils. Their work has implications for the treatment of skin allergies and asthma. (more…)
Tübinger Biologen weisen den „parentalen Umwelteffekt“ in der Praxis nach – und wie dieser evolutionär entsteht
Pflanzen können nicht nur Genvarianten an ihre Nachkommen weitergeben, sondern auch Informationen über Umwelterfahrungen, die sie selber gemacht haben. Dieses Phänomen wird als „parentaler Umwelteffekt“ bezeichnet, er wird sowohl von Klimabedingungen als auch von der Pflanzendichte beeinflusst, also dem Maß, in dem Pflanzen um Ressourcen konkurrieren. (more…)
AUSTIN, Texas — A strangely shaped depression on Mars could be a new place to look for signs of life on the Red Planet, according to a University of Texas at Austin-led study. The depression was probably formed by a volcano beneath a glacier and could have been a warm, chemical-rich environment well suited for microbial life. (more…)
Menthol improves the taste of nicotine in cigarettes and smokeless tobacco products and may help people develop and maintain their smoking and chewing habits, according to a new study by the Yale Tobacco Center of Regulatory Science (TCORS). (more…)
