Only half of Britons would definitely have Covid-19 vaccination

Survey sparks concern over misconceptions about vaccines and scepticism about science Coronavirus – latest updatesSee all our coronavirus coverageOnly half the population of Britain definitely would accept being vaccinated against Covid-19. That is the shock conclusion of a group of scientists and pollsters who have found that only 53% of a test group of citizens said they would be certain or very likely to allow themselves to be given a vaccine against the disease if one becomes available. Rel...

New USask-led research reveals previously hidden features of plant genomes

An international team led by the Plant Phenotyping and Imaging Research Centre (P2IRC) at the University of Saskatchewan (USask) and researchers at Agriculture and Agri-Food Canada (AAFC) has decoded the full genome for the black mustard plant--research that will advance breeding of oilseed mustard crops and provides a foundation for improved breeding of wheat, canola and lentils.

Indigenous property rights protect the Amazon rainforest

One way to cut back on deforestation in the Amazon rainforest - and help in the global fight against climate change - is to grant more of Brazil's indigenous communities full property rights to tribal lands. This policy focus is suggested by the findings of a new study in PNAS.

Grasshopper jumping on Bloch sphere finds new quantum insights

New research at the University of Warwick has (pardon the pun) put a new spin on a mathematical analogy involving a jumping grasshopper and its ideal lawn shape. This work could help us understand the spin states of quantum-entangled particles.

Mouthwashes could reduce the risk of coronavirus transmission

Sars-Cov-2 viruses can be inactivated using certain commercially available mouthwashes. This was demonstrated in cell culture experiments. High viral loads can be detected in the oral cavity and throat of some Covid-19 patients. The use of mouthwashes that are effective against Sars-Cov-2 could thus help to reduce the viral load and possibly the risk of coronavirus transmission over the short term.

Evolutionary assimilation of foreign DNA in a new host

Bioengineers at the University of California San Diego used genetic engineering and laboratory evolution to test the functionality of DNA placed into a new species and study how it can mutate to become functional if given sufficient evolutionary time.

Miscarriage risk increases each week alcohol is used in early pregnancy

Each week a woman consumes alcohol during the first five to 10 weeks of pregnancy is associated with an incremental 8% increase in risk of miscarriage, according to a study by Vanderbilt University Medical Center (VUMC) researchers.

NASA finds strong storms in developing Tropical Storm Mekkhala

After Tropical Depression 07W formed close to the western Philippines, it moved away and strengthened into a tropical storm in the South China Sea. NASA's Terra satellite provided a look at the strength of the storms that make up the tropical cyclone.

Poverty alleviation efforts are shaping the success of environmental targets

Social protection programs can facilitate progress towards the Sustainable Development Goals (SDGs) but can also create trade-offs across divergent social and environmental goals that can undermine their effectiveness, say the authors of new research published in the journal PNAS. This is one of the largest studies on the sustainability implications of social protection, funded by the Grantham Centre for Sustainable Futures at The University of Sheffield.

Schooling is critical for cognitive health throughout life

New research suggests that education provides little to no protection against the onset of cognitive declines later in life. It can, however, boost the cognitive skills people develop earlier in life, pushing back the point at which age-related dementia begins to impact a person's ability to care for themselves.

Coronavirus transmission risk increases along wildlife supply chains

Coronaviruses were detected in a high proportion of bats and rodents in Viet Nam from 2013 to 2014, with an increasing proportion of positive samples found along the wildlife supply chain from traders to large markets to restaurants, according to a study published August 10, 2020 in the open-access journal PLOS ONE by Amanda Fine of the Wildlife Conservation Society and colleagues.

Agriculture replaces fossil fuels as largest human source of sulfur to the environment

Historically, coal-fired power plants were the largest source of reactive sulfur, a component of acid rain, to the biosphere. A new study shows that fertilizer and pesticide applications to croplands are now the most important source of sulfur to the environment.

Analysis of Ugandan cervical carcinomas, an aid for understudied sub-Saharan women

Cervical cancer kills more than 300,000 middle-aged women a year, and 19 of the 20 nations with the highest death rates are sub-Saharan countries. Now an international team, including Akinyemi I. Ojesina, M.D., Ph.D., University of Alabama at Birmingham, has published the first comprehensive genomic study of cervical cancers in sub-Saharan Africa, with a focus on tumors from 212 Ugandan patients with cervical cancer.

Wheat and couch grass can extract toxic metals from contaminated soils

Irina Shtangeeva is a researcher at the Department of Soil Science and Soil Ecology, St Petersburg University. She has studied the ability of wheat and couch grass to accumulate toxic substances. Both plants were capable of absorbing various chemical elements from contaminated soils. Although the plants were able to accumulate high concentrations of toxicants, they could survive under negative environmental conditions

Nutritional screening a potential tool for determining heart attack, angina prognosis

In a study published today in the Journal of the American College of Cardiology of more than 5,000 acute coronary syndromes (ACS) patients, 71.8% were considered malnourished by at least one nutrition screening test, and worsening malnutrition status was associated with higher mortality and major adverse cardiovascular events (MACE), such as another heart attack or stroke.

New model shows how voting behavior can drive political parties apart

If voters gravitate toward the center of the political spectrum, why are the parties drifting farther apart? A new model reveals a mechanism for increased polarization in US politics, guided by the idea of 'satisficing'-- that people will settle for a candidate who is 'good enough.'

New global study shows 'best of the last' tropical forests urgently need protection

The world's 'best of the last' tropical forests are at significant risk of being lost, according to a paper released today in Nature Ecology and Evolution. Of these pristine forests that provide key services--including carbon storage, prevention of disease transmission and water provision--only a mere 6.5 percent are formally protected.

How maths modelling helps efforts to eradicate banana bunchy top virus, QUT study

Modelling the predicted movements of pervasive sap-sucking tiny insects before they infest banana crops has the potential to become a key tactic in the fight against a devastating virus, according to QUT research. Banana bunchy top virus (BBTV) is an aphid-transmitted banana disease that has been in Australia since 1913. QUT researchers have designed a model that tracked the probability of a banana plant being infected by aphids that carried the disease, with the findings published in PLOS Compu...

Previously undescribed lineage of Archaea illuminates microbial evolution

Stronger rains in warmer climate could lessen heat damage to crops, says study

Intensified rainstorms predicted for many parts of the United States as a result of warming climate may have a modest silver lining: they could more efficiently water some major crops, and this would at least partially offset the far larger projected yield declines caused by the rising heat itself.

KIST finds clue to improve artificial vision for patients with retinitis pigmentosa

A Korean research team has reported important findings that could potentially improve the performance of retinal prostheses creating artificial vision for blind individuals. The Korea Institute of Science and Technology (KIST) had found retinal neural signals arising from electric stimulation are altered depending on disease progression in mice affected by outer retinal degeneration. This research was done in collaboration with Harvard Medical School, Massachusetts General Hospital.
