- The solar system follows the galactic standard—but it is a rare breedon November 30, 2020 at 9:27 pm
Researchers at the Niels Bohr Institute, University of Copenhagen, have investigated more than 1000 planetary systems orbiting stars in our own galaxy, the Milky Way, and have discovered a series of connections between planetary orbits, number of planets, occurrence and the distance to their stars. It turns out that our own solar system in some ways is very rare, and in others very ordinary.
- Business closures, partial reopenings due to COVID-19 could cost the US $3-5 trillion in GDP over 2 yearson November 30, 2020 at 9:25 pm
The COVID-19 pandemic could result in net losses from $3.2 trillion and up to $4.8 trillion in U.S. Real Gross Domestic Product (GDP) over the course of two years, a new USC study finds.
- New study shows how methan breaks through icy barriers on the sea flooron November 30, 2020 at 9:25 pm
Methane, the main component of natural gas, is the cleanest-burning of all the fossil fuels, but when emitted into the atmosphere it is a much more potent greenhouse gas than carbon dioxide. By some estimates, seafloor methane contained in frozen formations along the continental margins may equal or exceed the total amount of coal, oil, and gas in all other reservoirs worldwide. Yet, the way methane escapes from these deep formations is poorly understood.
- Magnetic vortices come full circleon November 30, 2020 at 9:24 pm
Magnets often harbor hidden beauty. Take a simple fridge magnet: Somewhat counterintuitively, it is 'sticky' on one side but not the other. The secret lies in the way the magnetisation is arranged in a well-defined pattern within the material. More intricate magnetization textures are at the heart of many modern technologies, such as hard disk drives. Now, an international team of scientists at the Paul Scherrer Institute PSI, ETH Zurich, the University of Cambridge, the Donetsk Institute for […]

- Astronomical instrument hunts for ancient metalon November 30, 2020 at 9:24 pm
Researchers created a new astronomical instrument that has successfully aided in estimating the abundance of metals in the early universe. The WINERED instrument allows for better observations of astronomical bodies like quasars in the early universe, billions of years ago. Researchers hope this deeper level of exploration could help answer questions about the origins not only of metals in the universe but also of the stars themselves.

To develop effective therapeutics against pathogens, scientists need to first uncover how they attack host cells. An efficient way to conduct these investigations on an extensive scale is through high-speed screening tests called assays.
- Even razor clams on sparsely populated Olympic Coast can't escape plastics, study findson November 30, 2020 at 9:23 pm
Portland State University researchers and their collaborators at the Quinault Indian Nation and Oregon State University found microplastics in Pacific razor clams on Washington's sparsely populated Olympic Coast—proof, they say, that even in more remote regions, coastal organisms can't escape plastic contamination.
- Researching on-chip erbium-doped lithium niobate microcavity laserson November 30, 2020 at 9:22 pm
As a complement to silicon-based photonic chips, lithium niobate thin film (LNOI) has become a research hotspot in the field of optoelectronic integration due to its outstanding nonlinear, electro-optic, acousto-optic, piezoelectric and other physical properties. On-chip integrated frequency multipliers, modulators, and filters based on lithium niobate thin films have been developed, but the on-chip integrated communication band light source is still in urgent need of development. Recently, […]
- Seismic guidelines underestimate impact of 'The Big One' on metro Vancouver buildingson November 30, 2020 at 9:22 pm

- The wily octopus: King of flexibilityon November 30, 2020 at 9:22 pm
Octopuses have the most flexible appendages known in nature, according to a new study in Scientific Reports. In addition to being soft and strong, each of the animal's eight arms can bend, twist, elongate and shorten in many combinations to produce diverse movements. But to what extent can they do so, and is each arm equally capable? Researchers at the Marine Biological Laboratory (MBL) filmed 10 octopuses over many months while presenting them with a variety of challenges, and recorded 16,563 […]
- Researchers explore population size, density in rise of centralized power in antiquityon November 30, 2020 at 9:21 pm
Early populations shifted from quasi-egalitarian hunter-gatherer societies to communities governed by a centralized authority in the middle to late Holocene, but how the transition occurred still puzzles anthropologists. A University of Maine-led group of researchers contend that population size and density served as crucial drivers.

- Experimental vaccine for deadly tickborne virus effective in cynomolgus macaqueson November 30, 2020 at 8:13 pm
An experimental vaccine developed in Europe to prevent infection by Crimean-Congo hemorrhagic fever virus (CCHFV) has protected cynomolgus macaques in a new collaborative study from National Institutes of Health scientists. The animals received the DNA-based candidate vaccine through intramuscular injection immediately followed by electroporation—a process in development for human vaccines that helps cells absorb DNA. The study, published in Nature Microbiology, comes about three years after […]
- Could private investment finance conservation?on November 30, 2020 at 8:12 pm
Most of the money for protecting and conserving wildlife and habitat comes from government programs, philanthropic organizations, or the public. But conserving Earth's ecosystems and species requires hundreds of billions dollars more than what is currently spent. Fortunately, there might be another way. A new report called Innovative Finance for Conservation: Roles for Ecologists and Practitioners, explores how private investment could boost conservation in a big way. The report, which has just […]

- Unexpected similarity between honey bee and human social lifeon November 30, 2020 at 8:00 pm
Bees and humans are about as different organisms as one can imagine. Yet despite their many differences, surprising similarities in the ways that they interact socially have begun to be recognized in the last few years. Now, a team of researchers at the University of Illinois Urbana-Champaign, building on their earlier studies, have experimentally measured the social networks of honey bees and how they develop over time. They discovered that there are detailed similarities with the social […]

- Customized programming of human stem cellson November 30, 2020 at 7:47 pm
Induced pluripotent stem cells (iPS) have the potential to convert into a wide variety of cell types and tissues for drug testing and cell replacement therapies. However, the "recipes" for this conversion are often complicated and difficult to implement. Researchers at the Center for Regenerative Therapies Dresden (CRTD) at TU Dresden, Harvard University (U.S.) and the University of Bonn have found a way to systematically extract hundreds of different cells quickly and easily from iPS using […]
- Family pigs prefer their owner's company as dogs do, but they might not like strangerson November 30, 2020 at 7:46 pm
Researchers at ELTE Department of Ethology in Budapest compared how young companion dogs and companion pigs seek human proximity in a novel environment. It turned out that both dogs and pigs stay close to their owner if no other person is present; but if a stranger is also there, only dogs stay near humans, pigs prefer to stay away. The study reveals that while living in a human family is not enough for early developing a general human preference in companion animals, species differences weigh […]

- Biodiesel made from discarded cardboard boxeson November 30, 2020 at 7:46 pm
Automobile exhaust emitted by fossil-fuel-based vehicles, especially those operating on diesel, is known to be a major source of fine dust and greenhouse gases. Using biodiesel instead of diesel is an effective way of coping with climate change caused by greenhouse gases while reducing fine dust emission. However, the current method of producing biodiesel by chemically processing vegetable oil or waste cooking oil-such as palm or soybean oil-is limited because of the unreliable availability of […]
