Shedding light on the secret reproductive lives of honey bees
Honey bee health has been on the decline for two decades, with U.S. and Canadian beekeepers now losing about 25 to 40% of their colonies annually. And queen bees are failing faster than they have in the past in their ability to reproduce. The reason has been a mystery, but researchers at North Carolina State University and the University of British Columbia are finding answers.

Scientists model protein behavior of archaeal viruses to crack protein folding mystery
Scientists from the Pacific Quantum Center of Far Eastern Federal University (FEFU) report that the slipknot-structure AFV3-109 protein folds and unfolds depending on temperature. The protein is typical for the archaea, viruses of the oldest single-celled organisms that can survive in the extreme conditions of underwater volcanic sources. The research appears in PLOS ONE.
Earth to reach temperature tipping point in next 20 to 30 years, new study finds
Earth's ability to absorb nearly a third of human-caused carbon emissions through plants could be halved within the next two decades at the current rate of warming, according to a new study in Science Advances by researchers at Northern Arizona University, the Woodwell Climate Research Center and the University of Waikato, New Zealand. Using more than two decades of data from measurement towers in...
Early COVID-19 lockdowns had less impact on urban air quality than first believed
The first COVID-19 lockdowns led to significant changes in urban air pollution levels around the world, but the changes were smaller than expected—a new study reveals.
'Ocean 100': Small group of companies dominates ocean economy
Most of the revenues extracted from use of the world's oceans is concentrated among 100 transnational corporations, which have been identified for the first time by researchers at Duke University and the Stockholm Resilience Centre at Stockholm University.
Wormholes may be lurking in the universe—and new studies are proposing ways of finding them
Albert Einstein's theory of general relativity profoundly changed our thinking about fundamental concepts in physics, such as space and time. But it also left us with some deep mysteries. One was black holes, which were only unequivocally detected over the past few years. Another was "wormholes"—bridges connecting different points in spacetime, in theory providing shortcuts for space travelers.

Compound from medicinal herb kills brain-eating amoebae in lab studies
Primary amoebic meningoencephalitis (PAM), a deadly disease caused by the "brain-eating amoeba" Naegleria fowleri, is becoming more common in some areas of the world, and it has no effective treatment. Now, researchers reporting in ACS Chemical Neuroscience have found that a compound isolated from the leaves of a traditional medicinal plant, Inula viscosa or "false yellowhead," kills the amoebae...
Astronomers find signature of magnetar outbursts in nearby galaxies
Apart from black holes, magnetars may be the most extreme stars in the universe. With a diameter less than the length of Manhattan, they pack more mass than that of our sun, wield the largest magnetic field of any known object—more than 10 trillion times stronger than a refrigerator magnet—and spin on their axes every few seconds.
Study looks at how land acquisitions affect climate change
In 2007, an increase in world food prices led to a global rush for land in the form of land grabs or large-scale land acquisitions. Over the last two decades, such acquisitions have resulted in millions of hectares of land changing hands in developing nations. Although such changeover can increase the cultivation of crops needed to feed the world's growing population and spark new agricultural...
Superheroes, foods and apps bring a modern twist to the periodic table
Many students, especially non-science majors, dread chemistry.

Mathematics explains how giant whirlpools form in developing egg cells
Egg cells are among the largest cells in the animal kingdom. If moved only by the random jostlings of water molecules, a protein could take hours or even days to drift from one side of a forming egg cell to the other. Luckily, nature has developed a faster way: cell-spanning whirlpools in the immature egg cells of animals such as mice, zebrafish and fruit flies. These vortices enable cross-cell...
