  • Algorithm uses mass spectrometry data to predict identity of molecules
    on 17/06/2021 at 21:10

    An algorithm designed by researchers from Carnegie Mellon University’s Computational Biology Department and St. Petersburg State University in Russia could help scientists identify unknown molecules. The algorithm, called MolDiscovery, uses mass spectrometry data from molecules to predict the identity of unknown substances, telling scientists early in their research whether they have stumbled on something new or merely rediscovered something already known.

  • Drought saps California reservoirs as hot, dry summer looms
    on 17/06/2021 at 21:08

    Each year Lake Oroville helps water a quarter of the nation’s crops, sustain endangered salmon beneath its massive earthen dam and anchor the tourism economy of a Northern California county that must rebuild seemingly every year after unrelenting wildfires.

  • After 9 years and $10M, Georgia spaceport nears FAA approval
    on 17/06/2021 at 21:08

    After nine years of planning and $10 million invested by local taxpayers, county officials in Georgia’s coastal southeast corner came a big step closer Thursday to winning federal approval of a project engineered to literally inject the local economy with rocket fuel.

  • EXPLAINER: What’s behind the heat wave in the American West?
    on 17/06/2021 at 21:06

    Much of the American West has been blasted with sweltering heat this week as a high pressure dome combines with the worst drought in modern history to launch temperatures into the triple digits, toppling records even before the official start of summer.

  • Intensive water management in California promotes ‘live fast, die young’ cycle in floodplain forests
    on 17/06/2021 at 21:02

    Woodlands along streams and rivers are an important part of California’s diverse ecology. They are biodiversity hotspots, providing various ecosystem services including carbon sequestration and critical habitat for threatened and endangered species. But our land and water use have significantly impacted these ecosystems, sometimes in unexpected ways.

  • Mountain fires burning higher at unprecedented rates
    on 17/06/2021 at 20:59

    Forest fires have crept higher up mountains over the past few decades, scorching areas previously too wet to burn, according to researchers from McGill University. As wildfires advance uphill, a staggering 11% of all Western U.S. forests are now at risk.

  • A new rapid assessment to promote climate-informed conservation and nature-based solutions

  • Changing a 2D material’s symmetry can unlock its promise
    on 17/06/2021 at 20:56

    Optoelectronic materials that are capable of converting the energy of light into electricity, and electricity into light, have promising applications as light-emitting, energy-harvesting, and sensing technologies. However, devices made of these materials are often plagued by inefficiency, losing significant useful energy as heat. To break the current limits of efficiency, new principles of light-electricity conversion are needed.

  • ‘Nanodecoy’ therapy binds and neutralizes SARS-CoV-2 virus
    on 17/06/2021 at 20:52

    Nanodecoys made from human lung spheroid cells (LSCs) can bind to and neutralize SARS-CoV-2, promoting viral clearance and reducing lung injury in a macaque model of COVID-19. By mimicking the receptor that the virus binds to rather than targeting the virus itself, nanodecoy therapy could remain effective against emerging variants of the virus.

  • How cells ‘read’ artificial ingredients tossed into genetic recipe
    on 17/06/2021 at 20:51

    If the genome is the recipe of life, base pairs are the individual ingredients listed. These chemical structures form DNA, and every living organism on Earth has just four. The specific arrangements of these four base pairs—A, T, C, G—make us who and what we are.

  • Darwin May Have Got Sexual Selection Backwards
    on 18/06/2021 at 11:12

    Charles Darwin was a careful scientist. In the middle of the 19th century, while he was collecting evidence for his theory that species evolve by natural selection, he noticed it didn&rsquo;t explain the fancy tails of male peacocks, the antlers paraded by male deer, or why some the males of some species are far larger then their female counterparts. For these quirks, Darwin proposed a secondary theory: the sexual selection of traits that increase an animal&rsquo;s chance of securing a mate and reproducing. He carefully distinguished between weapons such as horns, spurs, fangs and sheer size…

  • The Problem With 'Survival of the Fittest'
    on 18/06/2021 at 11:12

    Today, Charles Darwin’s On the Origin of Species is recognized as one of the greatest books in scientific history, but when it was initially published, the broad reaction was hostile. Laypersons in general were uncomfortable with, and even insulted by, the ramifications of evolution by means of natural selection. “Humans aren’t apes!” they proclaimed. One reader who was a fan was English polymath Herbert Spencer, who envisioned the concept of evolution touching culture, ethics, and even the human mind. Spencer did have one key nitpick, however. He thought that the phrase “survival of the…

  • Five Unproven Claims That Alien Life Exists

    A recent study claims to have found evidence for mushroom-like life forms on the surface of Mars.

They are not, in fact, living organisms at all, but &ldquo;haematite concretions&rdquo; &ndash; small sphere-shaped pieces of the mineral haematite, and their exact origin is still debated by scientists. Haematite is a compound of iron and oxygen and is commercially important on Earth. The spherical rocks on Mars may have…

    “I have come to the conclusion that Darwinism is not a testable scientific theory, but a metaphysical research programme&mdash;a possible framework for testable scientific theories.” To biologists, these words, spoken by eminent philosopher of science Karl Popper, might seem like a betrayal. To creationists, a victory. Popper, the ardent empiricist and architect of falsifiability &ndash; the notion that for something to be scientific it must be testable &ndash; seemed to have doubts about evolution by means of natural selection. It’s partially true, but only in a philosophical, some might say…

The deadline for a challenge is June 2. Without allocated spectrum, certain transportation-related technology will be jeopardized. American drivers will have higher accident rates, and American companies will not be able to develop lifesaving technologies. Any agency or company can ask a judge to reexamine the FCC&rsquo;s rule….

    The 2020-2021 flu season was the most extraordinary in recent memory. As fall turned to winter, we physicians and hospitals braced for influenza cases piled atop already dire COVID-19 numbers. If it was anything like the 2019-2020 season, there could be about four hundred thousand additional hospitalizations. Given the nature of the flu, these cases would require much the same equipment and interventions as COVID-19 sufferers. The expected burden on infrastructure and providers was immense. The American healthcare system braced, and waited. Then the extraordinary thing happened:…
