Coronavirus: US bars foreign nationals who have recently travelled to China

CDC says situation in China ‘serious’ but risk to US public lowTemporary ban for non-Americans travelling from ChinaWhat is the coronavirus and how worried should we be?The Trump administration has declared a public health emergency over the coronavirus outbreak and announced it will temporarily bar entry to the US for people traveling from China unless they are Americans or immediately...

As our planet gets greener, plants are slowing global warming

Chi Chen, a Boston University graduate researcher, and Ranga Myneni, a BU College of Arts & Sciences professor of earth and environment, released a new paper that reveals how humans are helping to increase the Earth's plant and tree cover, which absorbs carbon from the atmosphere and cools our planet. The boom of vegetation, fueled by greenhouse gas emissions, could be skewing our perception of...

Ultra-high energy events key to study of ghost particles

Physicists at Washington University in St. Louis have proposed a way to use data from ultra-high energy neutrinos to study interactions beyond the standard model of particle physics. The 'Zee burst' model leverages new data from large neutrino telescopes such as the IceCube Neutrino Observatory in Antarctica and its future extensions.

Seeking better guidelines for inventorying greenhouse gas emissions

In the face of a changing climate, the process of accounting greenhouse gas emissions is becoming ever more critical. Governments around the world are striving to hit reduction targets using Intergovernmental Panel on Climate Change (IPCC) guidelines to limit global warming. To have a chance of hitting these targets, they need to know how to accurately calculate and report emissions and removals.

First view of hydrogen at the metal-to-metal hydride interface

University of Groningen physicists have visualized hydrogen at the titanium/titanium hydride interface using a transmission electron microscope. Using a new technique, they succeeded in visualizing both the metal and the hydrogen atoms in a single image, allowing them to test different theoretical models that describe the interface structure. The results were published on 31 January in the journal...

Red alert as Arctic lands grow greener

New research techniques are being adopted by scientists tackling the most visible impact of climate change - the so-called greening of Arctic regions. The latest drone and satellite technology is helping an international team of researchers to better understand how the vast, treeless regions called the tundra is becoming greener.

Ultra-high energy events key to study of ghost particles

Physicists propose a new way to leverage data from ultra-high energy neutrinos from large neutrino telescopes such as the IceCube Neutrino Observatory in Antarctica. So far, all nonstandard interaction studies at IceCube have focused only on the low-energy atmospheric neutrino data.

Britons on evacuation flight from Wuhan tell of relief and confusion

Some forced to leave behind loved ones due to short notice after China lifted restrictionsCoronavirus: live updatesBritons who were on board the evacuation flight from Wuhan have spoken of the confusion surrounding their departure, with some still having to leave loved ones behind.The flight, carrying 87 Britons and 27 foreign nationals from the coronavirus-hit Chinese city, touched down at RAF...

Simplifying simple sequence repeats

Simple sequence repeats (SSRs) are regions of DNA with high diversity, and they have long been a mainstay for botanists examining the genetic structure of plant populations. However, as the cost of sequencing DNA continues to plummet and genetic technologies advance, newer techniques for mapping genetic diversity such as genotyping-by-sequencing (GBS) or RAD-seq have begun to rival the traditional...

Young people putting music to the crisis: The role of music as a political expression

Songs that Sing the Crisis: Music, Words, Youth Narratives and Identities in Late Modernity is the title of a special issue of the journal Young (Nordic Journal of Youth Research) to be published on 1 February, now available online, that reflects on the role of music as an expression of the crisis. It contains case studies of musical genres rap, punk, folk metal, black metal, fado, reggaeton and...
