Our future climate depends partly on soil microbes—but how are they affected by climate change?
Plasma is matter that is so hot that the electrons are separated from atoms. The electrons float freely and the atoms become ions. This creates an ionized gas—plasma—that makes up nearly all of the visible universe. Recent research shows that magnetic fields can spontaneously emerge in a plasma. This can happen if the plasma has a temperature anisotropy—temperature that is different along...
Milk consumption increased ancient human body size, finds study
The largest terrestrial carbon sink on Earth is the planet's soil. One of the big fears is that a warming planet will liberate significant portions of the soil's carbon, turning it into carbon dioxide (CO2) gas, and so further accelerate the pace of planetary warming.
To reduce ‘reputational bias,’ NIH may revamp how grant proposals are scored
A new study led by Western biological anthropology professor Jay Stock, suggests that milk consumption in some regions between 7,000 and 2,000 years ago led to an increase in human body mass and stature. This ran counter to trends in body size experienced elsewhere in the world. This size increase is found in regions where there was evolution for higher frequencies of genes that allow humans to...
Study finds that UV-emitting nail polish dryers damage DNA and cause mutations in cells
Researchers familiar with the National Institutes of Health’s (NIH’s) peer-review process can cite many cases where the reputation of a scientist or their workplace seemed to count for more than the strength of their ideas. There was the scientist who moved from the Ivy League to a large public university and saw scores on his grant applications drop. The investigators from...
Standard reference cantilevers for atomic force microscopy spring constant calibration
The ultraviolet nail polish drying devices used to cure gel manicures may pose more of a public health concern than previously thought. Researchers at the University of California San Diego have studied these ultraviolet (UV) light emitting devices, and found that their use leads to cell death and cancer-causing mutations in human cells.
RNA lipid nanoparticle engineering stops liver fibrosis in its tracks, reverses damage
Atomic force microscopy (AFM) is a popular technique for interrogating surfaces on the micro and nano scales. The most common use for AFM is imaging; however, there are a variety of more specialized AFM techniques that can be used to determine electrical, mechanical, and chemical properties of surfaces. To adequately control the application of forces to surfaces for these techniques (especially...

Additionally, the certified values can be used to validate analytical methods for determining calcium and carbonate.
Researchers create new system for safer gene-drive testing and development
A newborn infant looks unmistakably hu
man, with legs, mouth, ears, and bottom all in place. The same can’t be said about the youngest sea stars, worms, or butterflies: Many invertebrates start out looking nothing like the adults they will become. Now, researchers have monitored one worm’s larval cells during the transfor
Circadian clock controls sunflower blooms, optimizing for pollinators
Scientists continue to expand the technological frontiers of CRISPR, along with its enormous potential, in areas ranging from human health to global food supplies. Such is the case with CRISPR-based gene drives, a genetic editing tool designed to influence how genetic elements are passed from one generation to the next.
Humans plunder the periodic table while turning blind eye to the risks of doing so, say researchers
An internal circadian clock controls the distinctive concentric rings of flowering in sunflowers, maximizing visits from pollinators, shows a new study from plant biologists at the University of California, Davis. The work is published Jan. 13 in eLife.
Scientists offer a new explanation for a mystery surrounding Jupiter's two massive asteroid swarms
For millions of years, nature has basically been getting by with just a few elements from the periodic table. Carbon, calcium, oxygen, hydrogen, nitrogen, phosphorus, silicon, sulfur, magnesium and potassium are the building blocks of almost all life on our planet (tree trunks, leaves, hairs, teeth, etc). However, to build the world of humans—including cities, health care products, railways,...
Flashes on the Sun Could Help Scientists Predict Solar Flares
An international team of scientists, including NYU Abu Dhabi researcher Nikolaos Georgakarakos and others from the U.S., Japan, and China, led by Jian Li from Nanjing University, has developed new insights that may explain the numerical asymmetry of the L4 and L5 Jupiter Trojan swarms, two clusters containing more than 10,000 asteroids that move along Jupiter's orbital path around the sun.

Modified CRISPR-based enzymes improve the prospect of inserting entire genes into the genome
A new study shows that global atmospheric dust—microscopic airborne particles from desert dust storms—has a slight overall cooling effect on the planet that has hidden the full amount of warming caused by greenhouse gases.
Measuring the enduring grip strength of the brown-throated sloth
Many genetic diseases are caused by diverse mutations spread across an entire gene, and designing genome editing approaches for each patient's mutation would be impractical and costly.

Flexible, wearable electronics woven into gear can reduce firefighters' rate of injury and mortality
MicroRNAs (miRNA) are small non-coding RNAs that regulate almost all biological processes, protein production, inflammatory responses, immune regulation, tumorigenesis and infection. In mammals, the classic formation of miRNA needs to transcribe a long primary miRNA in the nucleus and then process it into hairpin RNA with about 60–70 nucleotides. Eventually, this precursor miRNA will be...
