Just when you think Asian giant hornets' reputation couldn't get any worse, they're about to enter the "slaughter phase" when they attack in force, decapitate their victims and prey upon the brood for days.
Racial bias worse in police killings of older, mentally ill, unarmed men
The widely reported deaths of Michael Brown and Philando Castile reflect a grim truth in this country: According to data collected by The Washington Post, around 1,000 people are shot and killed by the police in the U.S. each year, and Black men are more than twice as likely to be victims as white men.
Corn farmers can apply a fungicide just once to protect against foliar diseases
Foliar diseases, such as gray leaf spot, northern corn leaf blight, and southern rust, were estimated to cause annual losses ranging from 19,029 to 244,149 metric tons from 2012 to 2015 in Kentucky. To mitigate these damages, farmers have turned to foliar fungicides. However, as plant pathologist Carl Bradley explains, "Kentucky corn farmers had questions about the best timing to apply a foliar...
Women, workers of color filling most 'high-hazard/low-reward' jobs in Washington

Normally an insulator, diamond becomes a metallic conductor when subjected to large strain in a new theoretical model
Long known as the hardest of all natural materials, diamonds are also exceptional thermal conductors and electrical insulators. Now, researchers have discovered a way to tweak tiny needles of diamond in a controlled way to transform their electronic properties, dialing them from insulating, through semiconducting, all the way to highly conductive, or metallic. This can be induced dynamically and...
Using physics to map the chaos of movement in living organisms
The behavior of living organisms might obey the same mathematical laws as physical phenomena, such as weather and the motion of planets, says new research from the Biological Physics Theory Unit at the Okinawa Institute of Science and Technology Graduate University (OIST).
Lego-like assembly of zeolitic membranes improves carbon capture
Zeolites are porous minerals that occur both naturally but also are being synthesized artificially. Because they are stable and durable, zeolites are used for chemical catalysis, purification of gases and liquids, and even in medical applications such as drug delivery and blood-clotting powders, e.g. the QuickClot trauma bandages used in the US military.
Revealing secret of lithium-rich stars by monitoring their heartbeats
Lithium is an ancient element that is almost as old as the universe itself. Though one of the building blocks of our present-day universe, lithium's presence in many celestial bodies often conflicts with predictions of classic theories.
Preserved dune fields offer insights into Martian history
The discovery of Martian dune fields largely preserved in the rock record for up to a billion years offers new insights on past climatic conditions on Mars.
It took several million years for Arrokothn to acquire its bizarre, pancake-flat shape
The trans-Neptunian object Arrokoth, also known as Ultima Thule, which NASA's space probe New Horizons passed on New Year's Day 2019, may have changed its shape significantly in the first 100 million years since its formation. In today's issue of the journal Nature Astronomy, researchers led by the Chinese Academy of Sciences and the Max Planck Institute for Solar System Research (MPS) suggest...
NASA's TESS creates a cosmic vista of the northern sky
NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered 74 exoplanets, or worlds beyond our solar system. Astronomers are sifting through some 1,200 additional exoplanet candidates, where potential new worlds await confirmation. More than 600 of these candidates lie in the northern sky.
For red abalone, resisting ocean acidification starts with mom
Red abalone mothers from California's North Coast give their offspring an energy boost when they're born that helps them better withstand ocean acidification compared to their captive, farmed counterparts, according to a study from the Bodega Marine Laboratory at the University of California, Davis.
Disproportionate extinction of South American mammals when Americas collided evident today
When the Isthmus of Panama rose from the sea to connect North and South America millions of years ago, mammals could cross the bridge in both directions. But the result of this massive migration—a large proportion of mammals with North American origins in South America, but not the other way around—has long puzzled paleontologists. To explore the origins of this drastic asymmetry, researchers...
Groundwater depletion in US High Plains leads to bleak outlook for grain production
The depletion of groundwater sources in parts of the United States High Plains is so severe that peak grain production in some states has already been passed, according to new research.
Snakes reveal the origin of skin colours
The skin color of vertebrates depends on chromatophores—cells found in the superficial layers of the epidermis. A team of specialists in genetic determinism and color evolution in reptiles from the University of Geneva (UNIGE) is studying the wide variety of colors sported by different individuals within the corn snake species. The research, published in the journal PNAS, demonstrates that the...
