Excavations at two quarries in Wales, known to be the source of the Stonehenge 'bluestones', provide new evidence of megalith quarrying 5,000 years ago, according to a new UCL-led study.
In a first-of-its-kind study from the Oxford Martin School, the climate-change impact of several production methods for lab-grown and farmed beef was assessed accounting for the differing greenhouse gases produced. The new projections reveal that over the long term, cultured meat production methods requiring large energy inputs could increase global warming more than some types of cattle farming if energy systems remain dependent on fossil fuels.
Liu's porous carbon fibers can enable high energy density and high electron/ion charging rates, which are typically mutually exclusive in electrochemical energy storage devices.
EPFL chemists have developed a light-based chemical method for cheap and simple production of chemical molecules used in drug discovery, such as muscle relaxants and antimicrobials.
Researchers at Tokyo Institute of Technology (Tokyo Tech) have designed a 28 GHz transceiver that integrates beamforming with dual-polarized multiple-input and multiple-output (MIMO) technology. Measuring just 3 mm by 4 mm, this tiny transceiver could help improve performances of fifth-generation cellular network (5G) and Internet of Things (IoT) devices.
Rutgers and other physicists have discovered an exotic form of electrons that spin like planets and could lead to advances in lighting, solar cells, lasers and electronic displays. It's called a 'chiral surface exciton,' and it consists of particles and anti-particles bound together and swirling around each other on the surface of solids, according to a study in the Proceedings of the National Academy of Sciences.
Houston Methodist scientists discovered a previously unknown trigger that turns run-of-the-mill strep infections into the flesh-eating disease childbed fever, which strikes postpartum moms and newborns, often leaving victims without limbs. Using an unprecedented approach, they looked at the interplay between the genome, transcriptome and virulence. This generated a massive data set, lending itself to artificial intelligence analysis. Through AI they unexpectedly discovered a new mechanism controlling virulence. The study appears Feb. 18 in Nature Genetics.
Researchers at Duke University have shown that a single systemic treatment using CRISPR genome editing technology can safely and stably correct a genetic disease -- Duchenne muscular dystrophy (DMD) -- for more than a year in mice, despite observed immune responses and alternative gene editing outcomes.
Hiroshima University, National Institute of Information and Communications Technology, and Panasonic Corporation announced the successful development of a terahertz (THz) transceiver that can transmit or receive digital data at 80 gigabits per second (Gbit/s). The transceiver was implemented using silicon CMOS integrated circuit technology, which would have a great advantage for volume production.
Tuberculosis (TB) is one of the top ten causes of death worldwide. The genome of the bacterium that causes TB holds a special toxin-antitoxin system with spectacular action: once the toxin is activated, all bacterial cells die, stopping the disease. An international research team co-led by the Wilmanns group at EMBL in Hamburg investigated this promising feature for therapeutic targets. They now share the first high-resolution details of the system in Molecular Cell.
