Induced-fit adsorbent for acetylene
We often say that a substrate fits into its enzyme like a key in a lock, but this metaphor is imperfect. Substrate binding can also change the lock (the structure of the enzyme) to induce a perfect fit. In the journal Angewandte Chemie, an internatio.....»»
Uber, Lyft use rides to vaccines to get drivers, customers back on the platform
Ride-hailing demand is ramping up from pandemic-induced lows, but drivers are still slow to return to the road, slowing the companies' efforts to rebuild revenues......»»
Melting ice sheets caused sea levels to rise up to 18 meters
It is well known that climate-induced sea level rise is a major threat. New research has found that previous ice loss events could have caused sea-level rise at rates of around 3.6 meters per century, offering vital clues as to what lies ahead should.....»»
EV industry bracing for long-term growth
Despite the pandemic-induced impacts, global electric vehicle (EV) shipments reached as high as 2.5 million units in 2020 - an achievement that has encouraged governments in advanced economies to accelerate policy formation that will be favorable to.....»»
India urged to extend production incentive program, say reports
Many handset and component manufacturers that have participated in India's five-year production-linked incentive (PLI) scheme have urged the Indian government to push back the program's timeline by a year as pandemic-induced impacts have disrupted th.....»»
Physical activity helps curb low-grade inflammation in children
According to a recent study, accumulating more brisk and vigorous physical activity can curb adiposity-induced low-grade inflammation. The study also reported that diet quality had no independent association with low-grade inflammation......»»
Robust and ultralow-energy-threshold ignition of lean fuels by an ultrashort-pulsed laser
Laser ignition (LI) is a promising electrode-less alternative to electronic spark ignition of lean fuel/air mixtures, offering high thermal efficiency with low harmful emissions. One of the most widely adopted LI methods is nanosecond laser-induced s.....»»
Researchers reveal missing optical localized gap modes
Electromagnetically induced transparency (EIT) is a typical quantum destructive interference effect, which possesses many striking properties such as elimination of optical absorption, reduction of group velocity and remarkable enhancement of Kerr no.....»»
Vaccine-induced antibodies may be less effective against several new SARS-CoV-2 variants
Researchers find that neutralizing antibodies raised by COVID-19 vaccines are not as effective at neutralizing some new, circulating SARS-CoV-2 variants......»»
Cancer cells may evade chemotherapy by going dormant
Cancer cells can dodge chemotherapy by entering a state that bears similarity to certain kinds of senescence, a type of 'active hibernation' that enables them to weather the stress induced by aggressive treatments aimed at destroying them, according.....»»
Degradable lignin-based polyurethane adsorbent for efficient crude oil cleanup
A research group led by Prof. Zhu Jin at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), has synthesized a high-efficiency carbon nanotube (CNT) modified lignin-based polyurethane adsorbe.....»»
Universal sequence of Chern insulators in superconducting magic angle graphene
Scientists from ICFO, Princeton and NIMS have discovered a full sequence of symmetry-broken Chern insulators that are induced by strong correlations in magic angle graphene. The study has been published in Nature Physics......»»
PCB shipments for high-end notebooks ramping up
Taiwan's notebook PCB suppliers are experiencing a rapid increase in the ratio of shipments for high-end applications and will see their overall shipments grow quarter by quarter in 2021 thanks to pandemic-induced demand remaining strong, according t.....»»
Determining the structure of a molecule with laser-induced electron diffraction
Light microscopes have revolutionized our understanding of the microcosmos, but their resolution is limited to about 100 nanometers. To see how molecules bond, break, or change their structure, we need at least 1000 times better resolution......»»
Grace Victory: YouTuber with Covid-19 "awake and baby thriving"
Grace Victory was in an induced coma after giving birth to her first child on Christmas Eve......»»
Egypt’s customer engagement platform for F&B brands in MENA, Koinz, raises $4.8M seed
As the restaurant industry across different cities was massively hit by the pandemic-induced lockdowns last year, food aggregator platforms helped by driving online customers to them. Koinz is one such startup in Egypt. Its value for food and beverag.....»»
Could "Topological Materials" Be A New Medium for Ultra-Fast Electronics?
Discovery of laser-triggered properties one step toward advanced quantum computers and high-speed, low-power devices Illustration: Ames Laboratory/U.S. Department of Energy Schematic of light-induced properties of the “topo.....»»
A deafening epidemic: The rise of noise-induced hearing loss, and how to stop it
Noise-induced hearing loss is a permanent condition that can happen slowly over time. Here's what you need to know to avoid the situations that can cause it......»»
Study reveals cause of 3-D asymmetry in inertial confinement fusion implosions
Inertial confinement fusion (ICF) implosions require very high levels of symmetry in order to reach the high densities and temperatures required for fusion induced self-heating. Even percent-level deviations from perfect spherical symmetry can lead t.....»»
Mechanism by which exercise strengthens bones and immunity
Scientists have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study also shows that movement-induced stimulation is required for the maintenance of this niche, as well a.....»»
Researchers use new tool to study stress in root-colonizing bacteria
One solution to agriculture's many challenges—climate change-induced drought, less arable land, and decreased water quality, to name a few—is to develop smarter fertilizers. Such fertilizers would aim not only to nourish the plant but also to max.....»»
