As governments prepare to gather in Yerevan, Armenia, this week for the U.N. Biodiversity Conference (COP17), new research identifies 13% of Earth's land area as hotspots for biodiversity conservation, highlighting where conservation efforts are most urgently needed.
A University of Mississippi study is adding nuance to a debate over how often police interrogation tactics can produce false confessions leading to wrongful convictions. In a recent simulation study published in the Journal of Criminal Justice, Ole Miss criminal justice and legal studies professors Mary Catlin and Thomas Bryan Smith found that the predicted likelihood of a false confession grows with the length of a police interrogation.
John Innes Centre researchers have trained scientists from across Tanzania to use new loop-mediated isothermal amplification (LAMP) assays to rapidly detect wheat blast, a looming fungal threat to wheat harvests.
The fusion of two cells is a decisive event in the sexual reproduction of many organisms. In fungi, cells must not only bring their membranes together and merge them, but also locally open their protective cell wall.
A new study, led by IIASA researchers and coauthored by UNEP colleagues, finds that if governments fully implement their methane reduction plans, they could reduce global emissions by 11% between 2020 and 2030. This would reverse the current trend of increasing methane emissions, but would not be sufficient to achieve the goal of the Global Methane Pledge.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) were surprised to discover the earliest phases of giant planet formation between the dense layers of gas and dust in the "Gomez's Hamburger" system, referred to as GoHam.
The gas orbiting Sagittarius A (Sgr A*), the supermassive black hole at the center of the Milky Way galaxy, is rich in metals, researchers at McGill University's Trottier Space Institute have found. The metal enrichment probably resulted from stars that exploded and released material into the black hole's surroundings over time, they said.
Earlier this year, I gave birth to my fourth child. My baby and I entered "karasunk," the traditional Armenian 40-day postpartum period during which mother and newborn remain close to home, sheltered from the outside world.
Every loaf of bread has a carbon footprint, a supply chain and a workforce behind it. As climate change, food safety and labor rights attract growing attention, corporate disclosures on environmental, social and governance (ESG) issues are becoming increasingly important. But what do companies disclose, and have their priorities changed?
Nearly all metabolic processes require protons—positively charged hydrogen atoms. Although these are abundant in the cellular fluid, the biocatalysts involved depend on mechanisms for efficiently capturing protons and transporting them to the site where catalysis occurs. Enzymes from microorganisms can produce hydrogen (H₂) by combining electrons with protons. These so-called hydrogenases are so efficient that one biocatalyst can capture nearly 10,000 protons per second.
