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...

Modeling study estimates spread of 2019 novel coronavirus

New modeling research estimates that up to 75,800 individuals in the Chinese city of Wuhan may have been infected with 2019 novel coronavirus (2019-nCoV) as of Jan. 25, 2020. The authors caution that given the lack of a robust and detailed timeline of records of suspected, probable, and confirmed cases and close contacts, the true size of the epidemic and its pandemic potential remains unclear.

Safe potassium-ion batteries

Scientists have developed a nonflammable electrolyte for potassium and potassium-ion batteries, for applications in next-generation energy-storage systems beyond lithium technology. Scientists explain that the novel electrolyte based on an organic phosphate makes the batteries safer and also allows for operation at reduced concentrations, which is a necessary condition for large-scale...

Study: Brexit referendum did not lead to more radical Euroskepticism elsewhere

Following the result of the UK Brexit referendum in June 2016 many Euroskeptic parties across Europe celebrated, contending that the vote could pave the way for similar referendums in other countries. This was explored in a paper, Eager to leave? Populist radical right parties' responses to the UK's Brexit vote, the lead author of which was Dr. Stijn van Kessel, Senior Lecturer in European...

University apologizes for saying xenophobia is 'common reaction' to coronavirus spread

University of California, Berkeley said on Instagram that spread of the illness may lead to ‘fears about interacting with those who might be from Asia’Coronovirus - latest updatesThe University of California, Berkeley apologized on Thursday evening for an Instagram posting that listed xenophobia and “fears about interacting with those who might be from Asia” as a common reaction to the...

New cobalt complex could reduce the cost of hydroformylation

A team of researchers from Louisiana State University and ExxonMobil Chemical has found a way to replace the rhodium catalysts used in the hydroformylation process. In their paper published in the journal Science, the group describes their process and how it compares economically with current methods.

Exploring the school-age social, emotional, and behavioral health landscape

How you interact, how you feel, and how you act: The three basic tenants of social, emotional, and behavioral health are simple concepts, yet they can be some of the strongest predictors of well-being as children grow into adulthood. While a large number of children and adolescents meet the diagnostic criteria for mental health disorders, only a fraction actually receive needed services—and it...

Efficient cryopreservation of genetically modified rat spermatozoa

Rat spermatozoa are two to four times larger than that of other animal species and are easily damaged by changes in pH, osmotic pressure, and temperature. Because these animals are very frequently used in medical research, a cryopreservation method was developed nearly 20 years ago. However, rat spermatozoa motility after thawing is extremely poor, and unless artificial insemination is performed...
