Changes to drylands with future climate change

While drylands around the world will expand at an accelerated rate because of future climate change, their average productivity will likely be reduced, according to a new study. These regions, which primarily include savannas, grasslands and shrublands, are important for grazing and non-irrigated croplands. They are also a critical part of the global carbon cycle and make up 41% of Earth's land...

Plant root hairs key to reducing soil erosion

The tiny hairs found on plant roots play a pivotal role in helping reduce soil erosion, a new study has found. The research provides compelling evidence that when root hairs interact with the surrounding soil they reduce soil erosion and increase soil cohesion by binding soil particles.

Tissue dynamics provide clues to human disease

Scientists have studied oscillating patterns of gene expression, coordinated across time and space within a tissue grown in vitro, to explore the molecular causes of a rare human hereditary disease known as spondylocostal dysostosis.

UK ministers struggle to keep promise of 100k coronavirus tests by end of April

Frustrated NHS staff and scientists say they have labs ready but cannot get the materialsCoronavirus – latest updatesSee all our coronavirus coverageThe UK government’s pledge to carry out 100,000 coronavirus tests a day by the end of the month is unravelling, with NHS laboratory staff and scientists warning they do not have the test kits, chemicals and components they need to scale up.Boris...

Research pinpoints which Australian cities take biggest economic blow from COVID-19

In an international collaboration between the University of South Australia Business School, the Hunter Foundation Research Centre at the University of Newcastle and George Mason University in Washington, D.C., researchers have pinpointed which Australian cities are most vulnerable to economic disruptions caused directly by the impacts of the COVID-19 pandemic.

New NASA radar looks to monitor volcanoes and earthquakes from space

Instead of looking up to the sky for bright bursts of fiery color, a research team spent Fourth of July 2018 peering down at fiery globs of molten lava from a sky-diving airplane. Bolted to their plane was a new NASA instrument designed to detect each time the volcano took a breath, as its caldera swelled and deflated.

Isolating an elusive phosphatetrahedrane

A research team in the Department of Chemistry at the Massachusetts Institute of Technology (MIT), Cambridge U.S., explored a synthetic pathway to generate a phosphatetrahedrane framework. During the synthetic route, the team replaced a single carbon vertex with another p-block element within a highly strained tetrahedrane molecule. Highly strained molecules possess unusually acute bond angles at...

Plant root hairs key to reducing soil erosion

The tiny hairs found on plant roots play a pivotal role in helping reduce soil erosion, a new study has found. The research, led by the University of Bristol and published in Communications Biology, provides compelling evidence that when root hairs interact with the surrounding soil they reduce soil erosion and increase soil cohesion by binding soil particles.

Do urban fish exhibit impaired sleep?

Melatonin controls the body clock—high melatonin levels make us feel tired in the evening. However, the hormone also plays an important role in animals' biological rhythms. Artificial light at night—light pollution—can suppress the production of melatonin in fish, even at very low light intensities, a finding established by researchers from the Leibniz-Institute of Freshwater Ecology and...

Capturing 3D microstructures in real time

Researchers have invented a machine-learning based algorithm for quantitatively characterizing material microstructure in three dimensions and in real time. This algorithm applies to most structural materials of interest to industry.

Melatonin controls the body clock -- high melatonin levels make us feel tired in the evening. However, the hormone also plays an important role in animals' biological rhythms. Artificial light at night -- light pollution -- can suppress the production of melatonin in fish, even at very low light intensities, a finding established by researchers.

First SARS-CoV-2 genomes in Austria openly available

The COVID-19 outbreak caused by the coronavirus SARS-CoV-2 was declared a pandemic by the World Health Organization (WHO) on 12 March 2020. It is thought to have been transmitted from wild animals to humans in the Chinese province of Hubei already in November 2019. More than 180 countries have been affected, and the COVID-19 disease already caused tens of thousands of deaths.

Using scattered light to map nerve fiber pathway crossing points in the brain

A team of researchers from Germany, the Netherlands and Italy has developed a way to use scattered light to map nerve fiber pathway crossing points in the brain. In their paper published in the journal Physical Review Letters, the group describes their work with light scattering in transmission microscopy and what it revealed in the human brain.
