Tech Xplore / At 0.8 nanometers, carbon film may replace two layers in future chip wiring
As transistors inside microchips continue to shrink, the metal wiring that connects them is becoming a growing obstacle to faster, more energy-efficient chips. Narrower wires have greater electrical resistance, while smaller ...
Phys.org / New measurements explain how silicon and diamond achieve extreme reversible stretching
A research team led by Yang Lu from the Department of Mechanical Engineering at the Faculty of Engineering, The University of Hong Kong (HKU), has uncovered the microscopic physical nature of ultralarge elasticity in covalent ...
Medical Xpress / Supercentenarians have an abundance of cancer-killing immune cells
The human immune system has specialized cells called CD4 cytotoxic T lymphocytes (CD4 CTLs), which have been shown to kill tumor cells in some cancers. When a person gets sick, these cells multiply in a process called clonal ...
Phys.org / Messy life-producing cellular process caught in action for first time
All living things have a fleet of tiny copy machines that turn instructions from DNA into RNA molecules responsible for helping build proteins that keep organisms alive. One of those nanoscale machines, called eukaryotic ...
Phys.org / Gold nanoclusters could help break down Alzheimer's amyloid plaques
Alzheimer's disease is a neurodegenerative brain disorder characterized by progressive memory loss and a decline in other mental functions. Past studies have consistently linked this disorder to the accumulation of the protein ...
Phys.org / Centuries-old physics test could help detect millicharged particles
Theoretical physicists have long predicted the existence of millicharged particles (mCPs), hypothetical particles that carry a very small electric charge. These particles are expected to interact very weakly with ordinary ...
Phys.org / 'Wall-to-wall' map of NYC trees could help cool cities worldwide
Researchers have created an interactive map identifying 1.8 million individual trees in New York City, using a new approach that could optimize the placement of trees for cooling in cities around the world.
Phys.org / Bipartisan majorities in US favor banning glyphosate
Two-thirds of Americans favor banning the use of the herbicide glyphosate, the active ingredient in the popular weedkiller Roundup, on crops grown in the United States, according to a nationally representative survey conducted ...
Medical Xpress / Gut bacteria may transform spinach, beets and plant iron into protective compounds
Researchers at Karolinska Institutet have discovered that gut bacteria can convert dietary nitrate and iron into protective molecules that may reduce the risk of cardiovascular and metabolic diseases. The study, published ...
Phys.org / Your high school friends may shape whether you become an entrepreneur decades later
With more young Canadians considering self-employment amid a high youth unemployment rate, entrepreneurship programs are facing growing demand. Applications to Futurpreneur, the national organization that finances young Canadian ...
Phys.org / Farm mice study shows antibiotic resistance is an environmental problem, not just a medical one
Scientists analyzed the genomes of gut microorganisms from an extensive population of 875 wild house mice (Mus musculus) collected from farms in Germany. They searched for genes responsible for resistance to common antibiotics ...
Phys.org / Rescue mission is called off for NASA's aging Swift space telescope
The mission to save NASA's sinking Swift Observatory was called off Wednesday, dooming the telescope to a fiery reentry later this year.
