Methane emissions from coal mines are higher than previously thought
2021-01-29
COLLEGE PARK, Md.--The amount of methane released into the atmosphere as a result of coal mining is likely much higher than previously calculated, according to research presented at the annual meeting of the American Geophysical Union recently.
The study estimates that methane emissions from coal mines are approximately 50 percent higher than previously estimated. The research was done by a team at the U.S. Department of Energy's Pacific Northwest National Laboratory, the U.S. Environmental Protection Agency and others.
The higher estimate is due mainly to two factors: methane that continues to be emitted from thousands of abandoned mines and the higher methane content in coal seams that are ever deeper, according to chief ...
Constructing the first version of the Japanese reference genome
2021-01-29
The Japanese now have their own reference genome thanks to researchers at Tohoku University who completed and released the first Japanese reference genome (JG1).
Their study was published in the journal Nature Communications on January 11, 2021.
"JG1 can aid with the clinical sequence analysis of Japanese individuals with rare diseases as it eliminates the genomic differences from the international reference genome," said Jun Takayama, co-author of the study.
Back in 2003, the Human Genome Project, through a gargantuan global effort, cracked the code of life and mapped all the genes of the human genome.
Since then, more accurate versions of the human reference genome have ...
Arctic warming and diminishing sea ice are influencing the atmosphere
2021-01-29
The researchers of the Institute for Atmospheric and Earth system research at the University of Helsinki have investigated how atmospheric particles are formed in the Arctic. Until recent studies, the molecular processes of particle formation in the high Arctic remained a mystery.
During their expeditions to the Arctic, the scientists collected measurements for 12 months in total. The results of the extensive research project were recently published in the Geophysical Research Letters journal.
The researchers discovered that atmospheric vapors, particles, and cloud formation have clear differences within various Arctic environments. The study clarifies how Arctic warming and sea ice loss strengthens processes where different vapors are emitted to the atmosphere. The ...

2021-01-29
The Covid-19 pandemic has made home offices, virtual meetings and remote learning the norm, and it is likely here to stay. But are people paying attention in online meetings? Are students paying attention in virtual classrooms? Researchers Jens Madsen and Lucas C. Parra from City College of New York, demonstrate how eye tracking can be used to measure the level of attention online using standard web cameras, without the need to transfer any data from peoples computers, thus preserving privacy. In a paper entitled "Synchronized eye movements predict test scores in online video education," published in the Proceedings of the National Academy of Sciences, they show that just ...
Synthesizing valuable chemicals from contaminated soil
2021-01-29
Scientists at Johannes Gutenberg University Mainz (JGU) and ETH Zurich have developed a process to produce commodity chemicals in a much less hazardous way than was previously possible. Such commodity chemicals represent the starting point for many mass-produced products in the chemical industry, such as plastics, dyes, and fertilizers, and are usually synthesized with the help of chlorine gas or bromine, both of which are extremely toxic and highly corrosive. In the current issue of Science, the researchers report that they have been able to utilize electrolysis, i.e., the application of an electric current, to obtain chemicals known as dichloro and dibromo compounds, which can then be used to synthesize ...

A new study has found that mobile apps can play a vital role in helping immigrants integrate into new cultures, as well as provide physical and mental health benefits.
Researchers at Anglia Ruskin University (ARU) surveyed new migrants and refugees undertaking free beginners' language classes in Greece, often the first destination for people arriving into Europe from Africa and Asia, over a 10-month period.
The findings, published in the journal Computers in Human Behavior, show that those using mobile apps aided by artificial intelligence (AI), such as language assistants, customised information sites, or health symptom trackers, experienced ...
Prosopis juliflora acutely reduces water resources in Ethiopia, costing rural livelihoods
2021-01-29
New research has revealed how an invasion of the alien evergreen tree, Prosopis juliflora seriously diminishes water resources in the Afar Region of Ethiopia, consuming enough of this already scarce resource to irrigate cotton and sugarcane generating some US$ 320 million and US$ 470 million net benefits per year.
A team of Ethiopian, South African and Swiss scientists, including lead author Dr Hailu Shiferaw, Dr Tena Alamirew, and Dr Gete Zeleke from the Water and Land Resource Centre of Addis Ababa University, Ethiopia, and Dr Sebinasi Dzikiti from Stellenbosch University, ...
'Weak' and 'strong' cells bonding boosts body's diabetes fight
2021-01-29
Scientists have broadened our understanding of how 'weak' cells bond with their more mature cellular counterparts to boost the body's production of insulin, improving our knowledge of the processes leading to type 2 diabetes - a significant global health problem.
Type 2 diabetes mellitus occurs when β-cells cannot release enough insulin - a tightly controlled process requiring hundreds of such cells clustered together to co-ordinate their response to signals from food, such as sugar, fat and gut hormones.
An international research team - led by scientists at the University of ...
Threads that sense how and when you move? New technology makes it possible
2021-01-29
Engineers at Tufts University have created and demonstrated flexible thread-based sensors that can measure movement of the neck, providing data on the direction, angle of rotation and degree of displacement of the head. The discovery raises the potential for thin, inconspicuous tatoo-like patches that could, according to the Tufts team, measure athletic performance, monitor worker or driver fatigue, assist with physical therapy, enhance virtual reality games and systems, and improve computer generated imagery in cinematography. The technology, described today in Scientific Reports, adds to a growing number of thread-based ...

Alpine plants at risk of extinction following disappearing glaciers
2021-01-29
Beyond the ski slopes, one of the most iconic symbols of the Alps are the alpine flowers. These plants are not only beautiful -- they are also used in liqueurs and medicines, and they form the foundation of the local food chains. But a recent study in Frontiers in Ecology and Evolution shows that, although plant diversity may initially increase with glacier retreat, many of these species may soon become endangered.
"Our results indicate that plant diversity will ultimately decrease once the glaciers disappear -- and up to 22% of the species we analyzed may locally disappear or even go extinct once the glaciers are gone," says lead author Dr Gianalberto Losapio of Stanford University in the USA. "We show that 'not all species are equal before global warming' and that there are some species ...
Human activity caused the long-term growth of greenhouse gas methane
2021-01-29
Methane (CH4) is the second most important greenhouse gas after carbon dioxide (CO2). Its concentration in the atmosphere has increased more than twice since the preindustrial era due to enhanced emissions from human activities. While the global warming potential of CH4 is 86 times as large as that of CO2 over 20 years, it stays in the atmosphere for about 10 years, much shorter than more than centuries of CO2. It is therefore expected that emission controlling of CH4 can benefit for relatively short time period toward the Paris Agreement target to limit the global warming well below 2 degrees.

Obesity may exacerbate the effects of Alzheimer's disease, new study shows
2021-01-29
New research from the University of Sheffield has found being overweight is an additional burden on brain health and it may exacerbate Alzheimer's disease.
The pioneering multimodal neuroimaging study revealed obesity may contribute toward neural tissue vulnerability, whilst maintaining a healthy weight in mild Alzheimer's disease dementia could help to preserve brain structure.
The findings, published in The Journal of Alzheimer's Disease Reports, also highlight the impact being overweight in mid-life could have on brain health in older age.
Lead author of the study, Professor Annalena Venneri from the University of Sheffield's Neuroscience Institute and NIHR Sheffield Biomedical Research Centre, ...
Genetic screening before prescribing could benefit millions
2021-01-29
Four million UK patients could benefit annually from genetic testing before being prescribed common medicines, according to new research from the University of East Anglia (UEA) in collaboration with Boots UK and Leiden University (Netherlands).
Researchers looked through 2019 NHS dispensing data across the UK to see how many patients are started on new prescriptions each year that could be potentially optimised by genetic testing.
They studied 56 medicines, including antidepressants, antibiotics, stomach ulcer treatments and painkillers where there are known drug-gene interactions.
And they found that in more than one in five occasions (21.1 ...

The Lancet Public Health: Ethnic health disparities among older adults in England equivalent to 20-year age difference, even before COVID-19
2021-01-29
-- Experts call for policy reform to improve ethnic equity of socioeconomic opportunity, service provision, and health outcomes. They also call for long-term studies to investigate how structural and institutional racism generate these ethnic inequalities in health.
In 15 out of 17 minority ethnic groups, health-related quality of life in older age (over 55 year-olds) was worse on average for either men, women, or both, than for White British people according to an observational study published in The Lancet Public Health journal.
In five of those groups - Bangladeshi, Pakistani, ...
<i>The Lancet</i>: Study estimates that, without vaccination against 10 diseases, mortality in children under five would be 45% higher in low-income and middle-income countries
2021-01-29
Peer-reviewed / Simulation or Modelling / People
A new modelling study has estimated that from 2000 to 2030 vaccination against 10 major pathogens - including measles, rotavirus, HPV and hepatitis B - will have prevented 69 million deaths in low-income and middle-income countries (LMICs).
The study estimated that, as a result of vaccination programmes, those born in 2019 will experience 72% lower mortality from the 10 diseases over their lifetime than if there was no immunisation.
The greatest impact of vaccination was estimated to occur in children under five - mortality from the 10 diseases in ...
Scholars reveal the changing nature of U.S. cities
2021-01-28
Cities are not all the same, or at least their evolution isn't, according to new research from the University of Colorado Boulder.
These findings, out this week in Nature Communications Earth and Environment and Earth System Science Data, buck the historical view that most cities in the United States developed in similar ways. Using a century's worth of urban spatial data, the researchers found a long history of urban size (how big a place is) "decoupling" from urban form (the shape and structure of a city), leading to cities not all evolving the same--or even close.
The researchers hope that by providing this look at the past with this unique data set, they'll be able to glimpse the future, including the impact of population growth on cities or ...
Experiments show the record of early life could be full of "false positives"
2021-01-28
Boulder, Colo., USA: For most of Earth's history, life was limited to the microscopic realm, with bacteria occupying nearly every possible niche. Life is generally thought to have evolved in some of the most extreme environments, like hydrothermal vents deep in the ocean or hot springs that still simmer in Yellowstone. Much of what we know about the evolution of life comes from the rock record, which preserves rare fossils of bacteria from billions of years ago. But that record is steeped in controversy, with each new discovery (rightfully) critiqued, questioned, and analyzed from every angle. Even then, uncertainty ...
Immune system sets 'tripwire' to protect against viruses
2021-01-28
Scientists are opening new windows into understanding more about the constantly shifting evolutionary arms race between viruses and the hosts they seek to infect. Host organisms and pathogens are in a perennial chess match to exploit each other's weaknesses.
Such research holds tantalizing clues for human health since the immune system is on constant alert to deploy counter measures against new viral attacks. But unleashing too much of a defensive response can lead to self-inflicted tissue damage and disease.
A new study published in the journal eLife by biologists at the University ...
New biosensors quickly detect coronavirus proteins and antibodies
2021-01-28
Scientists have created a new way to detect the proteins that make up the pandemic coronavirus, as well as antibodies against it. They designed protein-based biosensors that glow when mixed with components of the virus or specific COVID-19 antibodies. This breakthrough could enable faster and more widespread testing in the near future. The research appears in Nature.
To diagnose coronavirus infection today, most medical laboratories rely on a technique called RT-PCR, which amplifies genetic material from the virus so that it can be seen. This technique requires specialized staff and equipment. It also consumes lab supplies ...
Study shows when housing quality is poor, children suffer
2021-01-28
Housing instability and homelessness are widely understood to have an impact on health, and certain housing problems have been linked to specific childhood health conditions, such as mold with asthma. But it has not been clear how overall housing quality may affect children--especially those who are at risk from other social determinants of health such as food insecurity or poverty.
A new nationally representative study in the Journal of Child Health Care, led by researchers at Nationwide Children's Hospital, has found poor-quality housing is independently associated with poorer pediatric health, ...
