In the ever-expanding search for energy resources, a new study has emerged from Mozambique's Maniamba Basin. A team led by Nelson Nhamutole, a Ph.D. student at the University of the Witwatersrand, and his team of scientists from around the world, sha.....»»
Global meta-analysis quantifies benefits of cover crop use
For years, both scientists and farmers have debated whether the use of cover crops—plants used to cover the ground after harvesting of main crops—have a positive or negative impact on subsequent crop yield. Hundreds of studies have been performed.....»»
Engineers develop innovative microbiome analysis software tools
Since the first microbial genome was sequenced in 1995, scientists have reconstructed the genomic makeup of hundreds of thousands of microorganisms and have even devised methods to take a census of bacterial communities on the skin, in the gut, or in.....»»
Geologists reveal mysterious and diverse volcanism in lunar Apollo Basin, Chang"e-6 landing site
The far side of the moon is a mysterious place that is never visible from the Earth. The most remarkable feature of the moon is its asymmetry between the lunar near side and far side in composition, crust thickness, and mare volcanism. Scientists hav.....»»
How NASA"s Roman mission will hunt for primordial black holes
Astronomers have discovered black holes ranging from a few times the sun's mass to tens of billions. Now a group of scientists has predicted that NASA's Nancy Grace Roman Space Telescope could find a class of "featherweight" black holes that has so f.....»»
Advanced experimental setup expands the hunt for hidden dark matter particles
Scientific evidence for dark matter comes from observing how it influences the motion of stars and galaxies. Scientists believe that dark matter may consist of particles. To search for these particles and their billiard ball-like collisions, research.....»»
Using algorithms to decode the complex phonetic alphabet of sperm whales
The allure of whales has stoked human consciousness for millennia, casting these ocean giants as enigmatic residents of the deep seas. From the biblical Leviathan to Herman Melville's formidable Moby Dick, whales have been central to mythologies and.....»»
What are nanoplastics? An engineer explains concerns about particles too small to see
It's become common to read that microplastics—little bits of plastic, smaller than a pencil eraser—are turning up everywhere and in everything, including the ocean, farmland, food and human bodies. Now a new term is gaining attention: nanoplastic.....»»
Number of religious "nones" has soared, but not number of atheists—social scientists want to know why
The number of individuals in the United States who do not identify as being part of any religion has grown dramatically in recent years, and "the nones" are now larger than any single religious group. According to the General Social Survey, religious.....»»
Researchers "unzip" 2D materials with lasers
In a new paper published on May 1 in the journal Science Advances, researchers at Columbia Engineering used commercially available tabletop lasers to create tiny, atomically sharp nanostructures, or nanopatterns, in samples of a layered 2D material c.....»»
Materials scientists reveal pathway for designing optical materials with specialized properties
While we usually think of disorder as a bad thing, a team of materials science researchers led by Rohan Mishra, from Washington University in St. Louis, and Jayakanth Ravichandran, from the University of Southern California, have revealed that—when.....»»
Seeing is believing: Observation of migrasomes
Migrasomes, novel organelles first reported by Professor Li Yu' s team in 2015, are vesicular structures with diameters ranging from 0.5 to 3 micrometers that form on the retraction fibers at the rear of migrating cells. These structures contain vari.....»»
Computer models show heat waves in north Pacific may be due to China reducing aerosols
A team of oceanographers and planetary scientists at the Ocean University of China, working with a pair of colleagues from the U.S. and one in Germany, has found via computer modeling, that recent heat waves in the north Pacific may be due to a large.....»»
Laboratory and natural strains of intestinal bacterium turn out to have similar mutational profiles
Understanding mutational processes in a cell offers clues to the evolution of a genome. Most actively, mutation processes are studied in human cancer cells, while other genomes are often neglected......»»
Why parrots sometimes adopt—or kill—each other"s babies
Infanticide and adoption in the animal kingdom have long puzzled scientists. While both males and females of many species are known to kill the babies of their rivals to secure sexual or social advantage, other animals have been observed caring for t.....»»
Scientists cook pancakes, Brussels sprouts and stir fry to detect an oxidant indoors for the first time
A feast cooked up by UBC researchers has revealed singlet oxygen indoors for the first time. The work is published in the journal Environmental Science: Atmospheres......»»
Dogma-challenging telomere findings may offer new insights for cancer treatments
A new study led by University of Pittsburgh and UPMC Hillman Cancer Center researchers shows that an enzyme called PARP1 is involved in repair of telomeres, the lengths of DNA that protect the tips of chromosomes, and that impairing this process can.....»»
New super-pure silicon chip opens path to powerful quantum computers
Researchers at the Universities of Melbourne and Manchester have invented a breakthrough technique for manufacturing highly purified silicon that brings powerful quantum computers a big step closer......»»
Accountability standards based on rules of democracy needed in times of rising political violence, scholar argues
When a family or group of friends sit down to play a familiar game they've played many times before, they generally don't need to refer to the rules—unless someone breaks them. The values of liberal democracy have been transgressed in numerous form.....»»
