Insects and diseases that damage crops are probably present in many places thought to be free of them, new research shows. Pests that have not been reported in a certain area are usually assumed to be absent, but analysis by the University of Exeter shows many pests are "currently unobserved, but probably present" (a likelihood of more than 75%).
University of Tokyo graduate student Yuuki Wada with colleagues from Japan discovers a connection between lightning strikes and two kinds of gamma-ray phenomena in thunderclouds. The research suggests that in certain conditions, weak gamma-ray glows from thunderclouds may precede lightning bolts and their accompanying gamma-ray flashes.
It is sometimes the relatively simple ideas that work best. A novel low-cost device, that can rapidly secure coral fragments to the reef, has been so successful at helping propagate coral on high value sections of Australia's Great Barrier Reef that the Australian and Queensland Governments have committed more funding to take the project further.
For decades, scientists studying a key climate phenomenon have been grappling with contradictory data that have threated to undermine confidence in the reliability of climate models overall. A new study, published today in Nature Geoscience, settles that debate with regard to the tropical atmospheric circulation.
Increased solar radiation penetrating through the damaged ozone layer is interacting with the changing climate, and the consequences are rippling through the Earth's natural systems, effecting everything from weather to the health and abundance of sea mammals like seals and penguins.
Against the background of global warming, extreme heat has occurred more frequently and caused adverse socioeconomic effects. In the midsummer of 2018, a severe extreme heat episode attacked Northeast Asia, causing numerous fatalities. For instance, the extreme heat that attacked Japan in July 2018 resulted in about 24 000 hospitalized patients and more than 90 deaths.
Researchers from MIPT, Skoltech, the Joint Institute for High Temperatures of the Russian Academy of Sciences, and Lomonosov Moscow State University have offered a new approach to oil composition analysis. They used high temperature and pressure to dissolve oil in water and analyze its composition. The new method is compliant with the green chemistry principle as it makes it possible to avoid using environmentally hazardous solvents. The paper was published in the Analytical and Bioanalytical Chemistry journal.
Virginia Tech researchers discovered that wheat plants "sneezing" off condensation can vastly impact the spread of spore-borne diseases, such as wheat leaf rust, which can cause crop yield losses of up to 20 percent or more in the United States and higher average losses in less developed agricultural nations.
Bacteria living on the skin of frogs could save them from a deadly virus, new research suggests. Ranavirus kills large numbers of European common frogs - the species most often seen in UK ponds - and is one of many threats facing amphibians worldwide.
New UC Riverside-led research settles a longstanding debate about whether the most ancient animal communities were deliberately mobile. It turns out they were, because they were hungry.
Research carried out by an international team led by scientists from Ludwig-Maximilians-Universitaet (LMU) in Munich and the University of Tübingen reveals aspects of the drinking and dietary habits of the Celts, who lived in Central Europe in the first millennium BCE.
New research shows an iceless Greenland may be in the future. If worldwide greenhouse gas emissions remain on their current trajectory, Greenland may be ice-free by the year 3000. Even by the end of the century, the island could lose 4.5% of its ice, contributing up to 13 inches of sea level rise.
In a paper to be published in the forthcoming issue in NANO, a team of researchers from Nanchang University have attempted to directly engineer the surface structure of Cu-based substrate to get a series of Ce-O-Cu catalysts for NH3-SCR of NO. The obtained catalysts were structured as CuO matrix with interactive surface composed by Cu(I)-Cu(II) and Ce(III)-Ce(IV) co-present species, exhibiting the distinct synergistic effect and leading to attractive catalytic performance even with SO2present in reactant mixture.
A collaborative team of scientists from the US and Australia has named a new plant species from the remote Outback. Bucknell University biology postdoctoral fellow Angela McDonnell and professor Chris Martine led the description of the plant that had confounded field biologists for decades because of the unusual fluidity of its flower form. The discovery, published in the open access journal PhytoKeys, offers a powerful example of the diversity of sexual forms found among plants.
More than 30 microbiologists from 9 countries have issued a warning to humanity - they are calling for the world to stop ignoring an 'unseen majority' in Earth's biodiversity and ecosystem when addressing climate change.
