Association of rideshare use with alcohol-associated motor vehicle crash trauma

2021-06-09
(Press-News.org) What The Study Did: This study looked at whether there was an association between rideshare use, motor vehicle crash traumas and impaired driving convictions in Houston, Texas, by comparing traumas and convictions before and after the introduction of Uber.

Authors: Christopher R. Conner, M.D., Ph.D., of the McGovern Medical School at the University of Texas Health Science Center at Houston, is the corresponding author.

COVID vaccine linked to low platelet count, nationwide study suggests

2021-06-09
A condition that affects the blood, known as idiopathic thrombocytopenic purpura (ITP), may be associated the Oxford-AstraZeneca vaccine in rare cases, research suggests. The very small increased risk of the condition - which is characterised by low platelet counts - is estimated to be 11 per million doses, similar to figures seen in vaccines for flu and MMR. A low number of platelets - blood cells that help prevent blood loss when vessels are damaged - can result in no symptoms or can lead to an increased risk of bleeding or, in some cases, clotting. Researchers say that the increased chance of developing ITP after receiving the vaccine remains smaller than the risk of developing it because of Covid-19 and should ...

An atomic look at lithium-rich batteries

An atomic look at lithium-rich batteries
2021-06-09
Batteries have come a long way since Volta first stacked copper and zinc discs together 200 years ago. While the technology has continued to evolve from lead-acid to lithium-ion, many challenges still exist--like achieving higher density and suppressing dendrite growth. Experts are racing to address the growing, global need for energy-efficient and safe batteries. The electrification of heavy-duty vehicles and aircraft requires batteries with more energy density. A team of researchers believes a paradigm shift is necessary to make a significant impact in battery technology for these industries. ...

Meiosis: Mind the gap

Meiosis: Mind the gap
2021-06-09
Scientists from the lab of Franz Klein from the Department of Chromosome Biology at the Max Perutz Labs, a joint venture of the University of Vienna and the Medical University of Vienna, have now discovered that cells sometimes liberate DNA fragments at sites of paired, or double, DSBs. Whilst this presents an obvious risk of germline mutations as a consequence of erroneous repair or of integration of fragments from elsewhere at break sites, it may also be a source of evolutionary diversity. The study is published as a research article in Nature. Genetic information in humans is encoded in 23 chromosome pairs, where one pair consists of two slightly different copies or homologs. One is inherited from the father and one from the mother. Human gametes, however, are haploid - they start ...

Innovation projects can reinvent the UN

2021-06-09
Researchers at the University of Geneva (UNIGE) demonstrate that innovative projects spearheaded by United Nations (UN) country offices are remodeling the institution and expanding its role. Digital initiatives, particularly those scaled through headquarters, were shown to have the strongest impact, changing ways of working, embedding new skills, and restructuring teams across the UN. These findings, published in the Journal of Management Studies, highlight that fostering even single innovative projects could lead to fundamental transformations in the UN. How do International Organizations build innovation capabilities ...

Solving mystery of the four-headed echidna penis

Solving mystery of the four-headed echidna penis
2021-06-09
Scientists from the University of Melbourne and University of Queensland have revealed the mystery behind the unique reproductive parts of the much-loved echidna. In the paper, "The Unique Penile Morphology of the Short-Beaked Echidna, Tachyglossus aculeatus", the team detail how the male monotreme's testes never descend, have no scrotum, and when not in use, their penis is stored internally. They also detail how the echidna penis has four heads, which are actually rosette-like glans at the end. Just two of the four glans ever become functional during erection ...

A study analyzes the risk of karst groundwater contamination to human consumption

A study analyzes the risk of karst groundwater contamination to human consumption
2021-06-09
Led by Professor Andreas Hartmann, from the University of Freiburg (Germany), the researchers analyzed the presence of several pollutants in water from many karst aquifers of Europe, North Africa, and the Middle East, relating fast infiltration processes to an increased concentration of these substances. The findings of this research are published in the scientific journal Proceedings of the National Academy of Sciences (PNAS). This way, they warn that during rainfall events -when aquifers recharge, especially during autumn rainfall- the concentration of pollutants and pathogenic microorganisms can significantly exceed the safe levels, causing serious consequences for human consumption. "About one quarter of the ...

Brain alterations detected in obese children

2021-06-09
Obesity is generally linked to poor eating habits and the availability of tasty, high-calorie foods. However, a new study led by researchers from the Magnetic Resonance Imaging Research Unit in the Department of Radiology at Hospital del Mar and the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, has found that more elements are involved. Thanks to images obtained by functional magnetic resonance imaging, the researchers found that certain parts of the brains of obese children show alterations with respect to normal-weight or overweight children of the same age. ...

A study shows the unexpected effect of black holes beyond their own galaxies

A study shows the unexpected effect of black holes beyond their own galaxies
2021-06-09
At the heart of almost every sufficiently massive galaxy there is a black hole whose gravitational field, although very intense, affects only a small region around the centre of the galaxy. Even though these objects are thousands of millions of times smaller than their host galaxies our current view is that the Universe can be understood only if the evolution of galaxies is regulated by the activity of these black holes, because without them the observed properties of the galaxies cannot be explained. Theoretical predictions suggest that as these black holes grow they generate sufficient energy to heat ...

Brain connections mean some people lack visual imagery

2021-06-09
New research has revealed that people with the ability to visualise vividly have a stronger connection between their visual network and the regions of the brain linked to decision-making. The study also sheds light on memory and personality differences between those with strong visual imagery and those who cannot hold a picture in their mind's eye. The research, from the University of Exeter, published in Cerebral Cortex Communications, casts new light on why an estimated one-three per cent of the population lack the ability to visualise. This phenomenon was named "aphantasia" by the University of Exeter's Professor Adam Zeman in 2015 Professor Zeman called those with highly ...

Study of hyperhomocysteinemia in rats elucidates tracks to treating migraine

Study of hyperhomocysteinemia in rats elucidates tracks to treating migraine
2021-06-09
Homocysteine (HCY) is a sulfur-containing aminoacid, which attract more and more attention as the increase of homocysteine level associates with a number of pathological conditions. Hyperhomocysteinemia (hHCY) is an elevation of HCY level in plasma and develops due to genetic mutations of enzymes involved in regulation of HCY metabolism, nutritional deficiencies of vitamins B12, B6 and folate; chronic renal failure; alcoholism, smoking, excess coffee consumption, hypothyroidism; taking a number of medications like antiepileptic drugs and LDOPA; and aging. hHcy is a well-known ...
