Phys.org / Plants may experience 'optical illusions' that affect their direction of growth
A new study from Tel Aviv University reveals how plants, despite having neither a brain nor a nervous system, integrate light coming from multiple directions to determine where to grow. The researchers show how this process ...
Phys.org / Stem cells in deep sleep may point to a secret reserve for lifelong blood renewal
Researchers at the German Cancer Research Center (DKFZ) and the HI-STEM Stem Cell Institute have discovered a group of particularly long-lived blood stem cells in mice. These cells remain in a dormant state for an exceptionally ...
Dialog / Magnetic nanocomposites could help shrink the components that power computer chips
When you think about making computer chips better, you probably think about transistors. My colleagues and I focused on a less visible part of the problem: the components that deliver power to those transistors. A chip needs ...
Phys.org / Deep-sea mussels trade tidal rhythms for a 24-hour cycle in the lab
Hydrothermal vents lie in perpetual darkness in the depths of the ocean, yet the cells of the vent mussel Bathymodiolus azoricus, which lives 1,700 meters (5,600 feet) below the surface, follow a 24-hour rhythm in the laboratory.
Phys.org / RNA-protein interactions could lead to new coronavirus drug targets
A study co-led by a University of California, Riverside, biomedical scientist has identified new targets for coronavirus antiviral drugs, including treatments that may be less vulnerable to the rapid evolution of these viruses.
Phys.org / Study reveals how coral-associated bacteria help corals survive extreme heat
A new study from NYU Abu Dhabi has revealed how coral-associated bacteria help corals withstand extreme heat by producing steroid hormones that strengthen their immune response.
Phys.org / Molecular dinitrogen anions pave the way for low-temperature ammonia synthesis
While ammonia (NH₃) is best known for its role in fertilizer production, it is attracting attention as a carbon-free hydrogen carrier, potentially offering a practical way to store and transport clean fuel. Despite this promise, ...
Phys.org / Long-term observations of marine clouds reveal how in-cloud motions shape rain
Research led by atmospheric scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory sheds new light on one of the fundamental challenges of weather forecasting: determining the conditions under ...
Phys.org / A new way to make better use of ruthenium in single-atom catalysts
Ruthenium (Ru) is a valuable metal used in catalysts to speed up chemical reactions in many industrial processes. It can help improve efficiency and reduce the energy needed for chemical production. However, because it is ...
Phys.org / Two new bandicoot species discovered after trawling through museum drawers
A 10-year scientific investigation of museum specimens has uncovered two previously unrecognized bandicoot species, expanded the known range of the iconic quenda (or southeastern brown bandicoot) and reshaped understanding ...
Phys.org / Pearls and bird feathers inspire simpler method for producing structural colors
Colors in nature are not always produced by pigments. Pearls, bird feathers, butterfly wings and opals display brilliant colors through the interaction of light with microscopic structures, a phenomenon known as structural ...
Phys.org / Breaking the ice: Scientists use attracting particles to form an anti-spin ice
In a recent Nature Communications study, researchers have reported the realization of an anti-spin ice, a system that does the opposite of conventional spin ices by breaking the ice rule that governs them.
