Phys.org / Neanderthal males, human females? How ancient attraction shaped the human genome
The human genome is a rich, complex record of migration, encounters, and inheritance written over thousands of millennia. Genomic research by members of Sarah Tishkoff's lab at the University of Pennsylvania are revisiting ...
Phys.org / Matching vibrations is all it takes to shut down superconductivity in a nearby crystal
The world is never really at rest. Even in a vacuum near ultracold temperatures where all classical motion should come to a halt, you'll find quantum fluctuations. In thin, two-dimensional materials, these include random ...
Phys.org / Grasslands are vanishing nearly four times faster than forests, global study finds
Along with forests, grasslands and wetlands are also being converted to cropland and pasture at an increasing rate around the world—often for livestock farming and the export of agricultural products. An international team ...
Phys.org / Mitochondria can reshape lipid storage in cells by repurposing a protein-insertion complex
A recent study by the University of Bonn and University Hospital Bonn and the University of Freiburg shows that the mitochondria appear to be able to influence the number of lipid droplets in the cell using a mechanism that ...
Phys.org / Undergrads expand the chemical toolbox for cancer drugs
Thanks to modern therapies, a cancer diagnosis is no longer an automatic death sentence. But many patients still suffer from unwanted side effects and limited efficacy. In a recent Bioconjugate Chemistry publication, William ...
Phys.org / Exceptionally preserved 551-million-year-old site suggests Avalon biota lasted longer
Researchers studying the soft-bodied Ediacaran biotas of the world generally accept that there are three distinct assemblages. The 575–560-million-year-old (Ma) Avalon Assemblage is best known from the Ediacaran of Newfoundland, ...
Phys.org / Single-celled organism becomes multicellular via three different pathways
Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger multicellular organism. A new ...
Phys.org / A new, useful absorption limit for ultra-thin films
The applications of ultrathin, conductive films such as those made of graphene have many applications, but it's been thought their efficacy is limited to absorbing only half of the incidental light at best. A research group ...
Phys.org / A cosmic explosion with the force of a billion suns went unseen—until we caught its echo
Some of the universe's most extreme explosions leave behind almost no trace. The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front plows into its surrounding ...
Phys.org / What does it mean to compute? Framework maps hidden computations running inside natural dynamic systems
Some computers are easy to spot. Artificial, human-built computers like those found in smartphones and laptops are abstract dynamic systems with observable computational elements like input, output, energy cost, and logical ...
Phys.org / Turning over a new leaf in analyses of natural products
Scientists have developed a new way to help understand what happens in the body when people consume a plant product and the many chemicals it contains. The Journal of Natural Products published the method to quickly analyze ...
Phys.org / Smart materials and drug delivery could exploit lipid molecules that reorganize at drying interfaces
Minor changes in moisture level can promote lipid molecules to reorganize themselves in biomaterial or biomembranes. This can affect how the skin, lungs and tear film protect us from dehydration. This new discovery from Lund ...
