| Designed antiviral proteins inhibit SARS-CoV-2 in the lab Posted: 09 Sep 2020 11:03 AM PDT Computer-designed miniproteins have now been shown to protect lab-grown human cells from SARS-CoV-2, the coronavirus that causes COVID-19. The lead antiviral candidate rivals the best-known SARS-CoV-2 monoclonal antibodies in its protective actions. The synthetic antiviral candidates were designed to prevent infection by interfering with the mechanism that coronaviruses use to break into and enter cells.      |
| Seeing objects through clouds and fog Posted: 09 Sep 2020 10:21 AM PDT Using a new algorithm, researchers have reconstructed the movements of individual particles of light to see through clouds, fog and other obstructions. |
| Physicists explain mysterious dark matter deficiency in galaxy pair Posted: 09 Sep 2020 10:21 AM PDT A new theory about the nature of dark matter helps explain why a pair of galaxies about 65 million light-years from Earth contains very little of the mysterious matter. |
| Physicists use classical concepts to decipher strange quantum behaviors in an ultracold gas Posted: 09 Sep 2020 10:20 AM PDT There they were, in all their weird quantum glory: ultracold lithium atoms in the optical trap. Held by lasers in a regular, lattice formation and 'driven' by pulses of energy, these atoms were doing crazy things. |
| AI used to show how hydrogen becomes a metal inside giant planets Posted: 09 Sep 2020 08:48 AM PDT Researchers have used a combination of AI and quantum mechanics to reveal how hydrogen gradually turns into a metal inside giant planets. |
| Artificial intelligence aids gene activation discovery Posted: 09 Sep 2020 08:48 AM PDT Scientists have long known that human genes are activated through instructions delivered by the precise order of our DNA. With the aid of artificial intelligence, researchers have solved a long-standing DNA activation code mystery. Their discovery, which they termed the downstream core promoter region (DPR), could eventually be used to control gene activation in biotechnology and biomedical applications. |
| Atomistic modelling probes the behavior of matter at the center of Jupiter Posted: 09 Sep 2020 08:48 AM PDT Scientists have developed a physics-based machine learning approach to examine the behavior of hydrogen at extremely high pressures. The model reveals evidence of continuous metalization, and so has significant implications for planetary science. More fundamentally, it shows the way ahead for a simulation-driven change in how we understand the behavior of matter in fields as diverse as drug development and alloys for automobiles. |
| Massive halo finally explains stream of gas swirling around the Milky Way Posted: 09 Sep 2020 08:48 AM PDT Astronomers have discovered that a halo of warm gas surrounding the Magellanic Clouds likely acts as a protective cocoon, shielding the dwarf galaxies from the Milky Way's own halo and contributing most of the Magellanic Stream's mass. |
| Sand-sized meteoroids are peppering asteroid Bennu Posted: 09 Sep 2020 08:48 AM PDT A new study posits that the major particle ejections off the near-Earth asteroid Bennu may be the consequence of impacts by small, sand-sized particles called meteoroids onto its surface as the object nears the Sun. |
| Do as plants do: Novel photocatalysts can perform solar-driven conversion of CO2 into fuel Posted: 09 Sep 2020 07:03 AM PDT Scientists develop a novel 'heterostructured' photocatalyst using titanium and copper, two abundant and relatively inexpensive metals. Their cost-effective synthesis procedure, coupled with the high stability of the photocatalyst, provides an economically feasible way to convert waste carbon dioxide and water into useful hydrocarbon fuels using endless sunlight. |
| Lecturer takes laptops and smart phones away and musters student presence Posted: 09 Sep 2020 07:02 AM PDT A Danish university lecturer experiments with banning screens in discussion lessons. A new study looks at the results, which include greater student presence, improved engagement and deeper learning. |
| Tool transforms world landmark photos into 4D experiences Posted: 09 Sep 2020 07:02 AM PDT Using publicly available tourist photos of world landmarks such as the Trevi Fountain in Rome or Top of the Rock in New York City, researchers have developed a method to create maneuverable 3D images that show changes in appearance over time. |
| New glove-like device mimics sense of touch Posted: 09 Sep 2020 07:02 AM PDT Engineers have invented a soft wearable device which simulates the sense of touch and has wide potential for medical, industrial and entertainment applications. |
| Australian telescope finds no signs of alien technology in 10 million star systems Posted: 09 Sep 2020 05:59 AM PDT A radio telescope in outback Western Australia has completed the deepest and broadest search at low frequencies for alien technologies, scanning a patch of sky known to include at least 10 million stars. Astronomers used the Murchison Widefield Array (MWA) telescope to explore hundreds of times more broadly than any previous search for extraterrestrial life. |
| Recharging N95 masks for continued usage Posted: 08 Sep 2020 08:32 AM PDT In a new article, researchers share a method to restore the filtration efficiency of N95 masks to out-of-box levels, as long as the mask is not structurally compromised. |
| Painting with light: Novel nanopillars precisely control intensity of transmitted light Posted: 04 Sep 2020 01:33 PM PDT By shining white light on a glass slide stippled with millions of tiny titanium dioxide pillars, researchers have reproduced with astonishing fidelity the luminous hues and subtle shadings of 'Girl With a Pearl Earring.' |
