    The P.1 coronavirus variant is twice as transmissible as earlier strains

    The variant first found in Brazil can evade some immunity from previous COVID-19 infections, making reinfections a possibility.

  2. illuistration of a pterosaur with opposable thumbs

    ‘Monkeydactyl’ may be the oldest known creature with opposable thumbs

    A newly discovered pterosaur that lived during the Jurassic Period could have used its flexible digits to climb trees like a monkey.

  3. crowd of Japanese commuters wearing masks

    A coronavirus epidemic may have hit East Asia about 25,000 years ago

    An ancient viral outbreak may have left a genetic mark in East Asians that possibly influences their responses to the virus that causes COVID-19.

    STEM’s racial, ethnic and gender gaps are still strikingly large

    Black and Hispanic professionals remain underrepresented in STEM, while women’s representation varies widely by STEM field, according to a new report.

    U.S. pauses J&J vaccine rollout after 6 people of 6.8 million get rare blood clots

    The COVID-19 vaccine’s pause is out of abundance of caution, experts say. The potentially deadly clots appear to be “extremely rare.”

  6. crowd of people screaming with joy

    Surprisingly, humans recognize joyful screams faster than fearful screams

    Scientists believed we evolved to respond to alarming screams faster than non-alarming ones, but experiments show our brains may be wired differently.

    Discarded COVID-19 PPE such as masks can be deadly to wildlife

    From entanglements to ingestion, two biologists are documenting the impact of single-use masks and gloves on animals around the world.

  8. fish swimming by coral reef

    Corals’ hidden genetic diversity corresponds to distinct lifestyles

    Observation and DNA analysis expose identical reef corals as distinct species with unique ecologies, suggesting much greater coral biodiversity.

    How researchers can keep birds safe as U.S. wind farms expand

    Tracking bald eagle abundance and migrating whooping cranes provides a clearer picture of where wind turbines could be safely built.

    A trek under Thwaites Glacier’s ice shelf reveals specific risks of warm water

    An underwater autonomous craft collected the first data on the chemistry of seawater eroding the icy underbelly of Antarctica’s Thwaites Glacier.

  11. dwarf galaxy HSC J1631+4426

    A record-breaking, oxygen-starved galaxy may be full of gigantic stars’ shrapnel

    The newly discovered galaxy may have once been home to stars more than 300 times as massive as the sun — a peek at conditions in the early universe.

  12. models of an early human skull and an apelike skull with brains highlighted in blue

    Ancient humans may have had apelike brains even after leaving Africa

    Modern humanlike brains may have evolved surprisingly late, about 1.7 million years ago, a new study suggests.
