This common vitamin deficiency can mimic normal aging

Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy. The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago. Today, researchers are finding that B12 may also help keep cellular p

AI reads 3D tooth microwear to reconstruct diets of early human ancestors

The study of dental microwear allows the analysis of the microscopic marks that foods leave on the surface of tooth enamel during mastication. In paleoanthropology, this methodology helps reconstruct the diet of fossil primates and hominins throughout human evolution. The microsc

How soil pH shapes rice stink bug outbreaks by controlling key bacteria

Researchers at the National Institute of Advanced Industrial Science and Technology (AIST), in collaboration with researchers from the University of the Ryukyus and the University of Electro-Communications, have discovered that soil pH is a key factor in regulating the symbiotic

Plankton-linked vapors could speed cloud seed formation over cold oceans

For nearly 50 years, scientists have suspected that microscopic marine plankton play a role in cloud formation over the oceans. Now, an experiment led by the University of Helsinki suggests that it may be more important than previously thought. The findings are published in the j

Microscale hydrogel fibers could enable imaging inside tiny tissue structures

Researchers have developed light-transmitting hydrogel fibers that are just hundreds of micrometers in diameter. With further development, these soft fibers could one day make it possible to use imaging techniques to detect early breast cancer hidden inside very small breast duct

Earth may have been seeding Venus with life for billions of years

A new study suggests Earth may have been sending tiny hitchhikers to Venus for billions of years. Researchers found that asteroid impacts could launch microbes into space, where some might survive the journey and end up suspended in Venus' clouds. If future missions detect life t

Laser-based 3D imaging system enables precise detection and quantification of methane leak

A research team led by Prof. Zhang Zhirong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a high-performance laser-based three-dimensional methane gas cloud imaging telemetry system that enabled visualization of microleakages, accur

Ancient algal defenses against UV may have helped plants conquer land

A new study sheds light on how the ancestors of modern land plants survived one of the most challenging aspects of life outside water: exposure to harmful ultraviolet (UV) radiation. By examining a microscopic alga closely related to the earliest land plants, researchers have unc

These tiny soil microbes could rescue crops from salty farmland

Researchers have discovered that beneficial soil bacteria give plants an unexpected survival advantage in salty soils. Instead of helping plants keep salt out, the microbes stimulate the production of lignin, a natural compound that strengthens roots and makes plants more resilie

Why nanoscale droplets don't coalesce and microscale droplets do

Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon chains, which makes it hydrophobic and insoluble

Tiny DNA 'hitchhikers' may be reshaping life in thawing Arctic soils

Amid the peatlands of northern Sweden, billions of microbes are quietly rewriting their genetic playbooks—and doing so far more often than scientists realized.
