Published Two-dimensional compounds can capture carbon from the air
(via sciencedaily.com) Original source Some of the thinnest materials known to humankind -- MXene and MBene compounds -- may provide solutions to scientists in their quest to curb the effects of global warming. These substances are only a few atoms thick, making them two-dimensional. Because of their large surface area, the materials have the potential to absorb carbon dioxide molecules from the atmosphere, which could help reduce the harmful effects of climate change by safely sequestering carbon dioxide, according to a review study.
Published New type of tiny wasp comes with mysterious, cloud-like structures at ends of antennae
(via sciencedaily.com) Original source Fossil researchers have discovered a novel genus and species of tiny wasp with a mysterious, bulbous structure at the end of each antenna.
Published New technology could reduce lag, improve reliability of online gaming, meetings
(via sciencedaily.com) Original source Whether you’re battling foes in a virtual arena or collaborating with colleagues across the globe, lag-induced disruptions can be a major hindrance to seamless communication and immersive experiences. That’s why researchers have developed new technology to make data transfer over optical fiber communication faster and more efficient.
Published Simultaneous large wildfires will increase in Western U.S.
(via sciencedaily.com) Original source Simultaneous outbreaks of large wildfires will become more frequent in the Western United States this century as the climate warms, putting major strains on efforts to fight fires, according to new research. The most severe wildfire seasons will become at least twice as frequent.
Published Study identifies jet-stream pattern that locks in extreme winter cold, wet spells
(via sciencedaily.com) Original source Winter is coming—eventually. And while the earth is warming, a new study suggests that the atmosphere is being pushed around in ways that cause long bouts of extreme winter cold or wet in some regions. The study’s authors say they have identified giant meanders in the global jet stream that bring polar air southward, locking in frigid or wet conditions concurrently over much of North America and Europe, often for weeks at a time. Such weather waves, they say, have doubled in frequency since the 1960s. In just the last few years, they have killed hundreds of people and paralyzed energy and transport systems.
Published Understanding greenhouse gases in oil palm plantations
(via sciencedaily.com) Original source The rapid spread of oil palm plantations and associated high use of fertilizer raises concerns about the emission of nitrous oxide, a powerful greenhouse gas. A new study shows that oil palms’ photosynthesis and their response to meteorological and soil conditions play an important but still widely unexplored role in the amount of nitrous oxide produced by oil palm plantations.
Published Hippos' prominent tusks and wide gaping mouths prevent efficient, grinding chewing
(via sciencedaily.com) Original source Hippos' huge tusks and wide gape restrict grinding jaw movements, making their chewing inefficient, according to a new study.
Published Prehistoric people occupied upland regions of inland Spain in even the coldest periods of the last Ice Age
(via sciencedaily.com) Original source Paleolithic human populations survived even in the coldest and driest upland parts of Spain, according to a new study.
Published Adoption of vegan dog and cat diets could have environmental benefits
(via sciencedaily.com) Original source A new analysis estimates a variety of potential benefits for environmental sustainability -- for instance, reduced freshwater consumption and greenhouse gas emissions -- that could result from switching all pet dogs and cats in the US or around the world to nutritionally sound, vegan diets.
Published Being a vegetarian may be partly in your genes
(via sciencedaily.com) Original source A person's genetic makeup plays a role in determining whether they can stick to a strict vegetarian diet, a new study has found. The findings open the door to further studies that could have important implications regarding dietary recommendations and the production of meat substitutes.
Published Early human migrants followed lush corridor-route out of Africa
(via sciencedaily.com) Original source Scientists have found early human migrants left Africa for Eurasia, across the Sinai peninsula and on through Jordan, over 80-thousand years ago. Researchers have proved there was a 'well-watered corridor' which funneled hunter-gatherers through The Levant towards western Asia and northern Arabia via Jordan.
Published Proteins roll the dice to determine bee sex
(via sciencedaily.com) Original source To date it has been unclear exactly how the sex of a bee is determined. A research team comprising biologists and chemists has now identified a key gene and the molecular mechanism linked with it. They describe how this process is similar to a game involving two dice.
Published Meadow Spittlebug's record-breaking diet also makes it top disease carrier for plants
(via sciencedaily.com) Original source New research fueled in part by citizen scientists reveals that the meadow spittlebug—known for the foamy, spit-like urine released by its nymphs—can feed on at least 1,300 species of host plants, more than twice the number of any other insect.
Published Staying dry for months underwater
(via sciencedaily.com) Original source Researchers have developed a superhydrophobic surface with a stable plastron that can last for months under water. The team’s general strategy to create long-lasting underwater superhydrophobic surfaces, which repel blood and drastically reduce or prevent the adhesion of bacterial and marine organisms such as barnacles and mussels, opens a range of applications in biomedicine and industry.
Published Hospital superbugs: Could one vaccine rule them all?
(via sciencedaily.com) Original source A new study shows that a single dose of the vaccine, administered in mouse models, put immune cells into 'Incredible Hulk' mode, providing rapid protection against nine different bacteria and fungi species that lurk in healthcare settings.
Published New 'Assembly Theory' unifies physics and biology to explain evolution and complexity
(via sciencedaily.com) Original source An international team of researchers has developed a new theoretical framework that bridges physics and biology to provide a unified approach for understanding how complexity and evolution emerge in nature. This new work on 'Assembly Theory' represents a major advance in our fundamental comprehension of biological evolution and how it is governed by the physical laws of the universe.
Published Ancient carbon in rocks releases as much carbon dioxide as the world's volcanoes
(via sciencedaily.com) Original source New research has overturned the traditional view that natural rock weathering acts as a carbon sink that removes CO2 from the atmosphere. Instead, this can also act as a large CO2 source, rivaling that of volcanoes.
Published Machine learning used to probe the building blocks of shapes
(via sciencedaily.com) Original source Applying machine learning to find the properties of atomic pieces of geometry shows how AI has the power to accelerate discoveries in maths.
Published Invertebrate biodiversity is improving in England's rivers, long-term trends show
(via sciencedaily.com) Original source Rivers across England have seen a significant improvement in river invertebrate biodiversity since 1989, shows a new study.
Published Volcanic ash effects on Earth systems
(via sciencedaily.com) Original source To bridge the knowledge gap between volcanologists and atmospheric scientists working on climate change and observing global systems, researchers have characterized volcanic ash samples from many explosive eruptions of a broad compositional range.
