The planetary system around star HR8799 is remarkably similar to our Solar System. A research team led by astronomers from the University of Groningen and SRON Netherlands Institute for Space Research has used this similarity to model the delivery of materials by asteroids, comets and other minor bodies within the system. Their simulation shows that the four gas planets receive material delivered by minor bodies, just like in our Solar System. The results were published by the journal Astronomy & Astrophysics on 29 May.
The identified genomic region includes several candidate genes associated with brain development and function as well as anxiety, whose further analysis may reveal new neural mechanisms related to fear.
For the purposes of the study, carried out by Professor Hannes Lohi's research group and published in the Translational Psychiatry journal, data from a total of 120 Great Danes was collected. The Great Dane breed is among the largest dog breeds in the world.
The article gives an overview of the spread of Covid-19 and outlines six causes of the crisis: the exponential infection rate, international integration, the insufficient capacity of health care systems in many countries, conflicts of competence and a lack of foresight on the part of many government agencies, the need to grapple with the economic impacts of the shutdown parallel to the health crisis, as well as weaknesses in capital markets resulting from the financial crisis of 2008.
A Bristol academic has achieved a milestone in statistical/mathematical physics by solving a 100-year-old physics problem - the discrete diffusion equation in finite space.
The long-sought-after solution could be used to accurately predict encounter and transmission probability between individuals in a closed environment, without the need for time-consuming computer simulations.
LA JOLLA, Calif. and JUPITER, Fla.- MAY 29, 2020 - Surgery would be inconceivable without general anesthesia, so it may come as a surprise that despite its 175-year history of medical use, doctors and scientists have been unable to explain how anesthetics temporarily render patients unconscious.
HOUSTON -- Patients with advanced non-small cell lung cancer (NSCLC) and the MET exon 14 (METex14) skipping mutation had a 46.5% objective response rate to the targeted therapy drug tepotinib, as shown in a study published today in the New England Journal of Medicine and presented at the 2020 American Society of Clinical Oncology (ASCO) Annual Meeting ASCO20 Virtual Meeting (Abstract 9556 - Poster 322) by researchers from The University of Texas MD Anderson Cancer Center.
High-throughput analysis of blood plasma could aid in identification of diagnostic and prognostic biomarkers for amyotrophic lateral sclerosis (ALS), according to research from North Carolina State University. The work sheds further light on a pathway involved in disease progression and appears to rule out an environmental neurotoxin as playing a role in ALS.
The addition of the monoclonal antibody therapy Trastuzumab to radiotherapy did not reach the protocol objective of a 36% reduction in the ipsilateral breast tumor recurrence rate for women with HER2-positive ductal carcinoma in situ (DCIS) on the NRG Oncology clinical trial NSABP B-43. The trial did find a statistically non-significant, modest (19%) reduction in the rate of recurrence among women that received trastuzumab, but this difference was not statistically significant.
ATLANTA--Paid sick leave (PSL) mandates like those found in the federal government's Families First Coronavirus Response Act may be helping to slow the spread of COVID-19, according to a new study by health economists at Georgia State and Tulane universities.
MINNEAPOLIS, MN- May 29, 2020 - According to the National Autism Association, people with autism spectrum disorder (ASD) may experience sensory hypersensitivity. A University of Minnesota Medical School researcher recently published an article in Nature Communications that illustrates why that may be true by showing the differences in visual motion perception in ASD are accompanied by weaker neural suppression in the visual cortex of the brain.
BUFFALO, N.Y. -- Harm reduction strategies have proven effective for use of opioids, alcohol, and tobacco products. University at Buffalo and University of Michigan researchers say harm reduction techniques also have potential for cannabis users - but first, public health practitioners and organizations need to do a better job of making cannabis users aware of those strategies.
Researchers assessed harm reduction awareness by surveying nearly 500 participants at the 2019 Hash Bash, a popular marijuana advocacy event on the campus of the University of Michigan.
Farmers in Bangladesh achieved significantly higher yields and revenues by growing insect-resistant, genetically engineered eggplant, a new Cornell study has found.
The four genetically engineered (Bt) varieties yielded, on average, 19.6% more eggplant - known as brinjal in Bangladesh - than non-Bt varieties and earned growers 21.7% higher revenue, according to the study, published May 25 in Frontiers in Bioengineering and Biotechnology.
A team of researchers led by Swansea University have developed new technology to monitor cholesterol in brain tissue which could uncover its relation to neurodegenerative disease and pave the way for the development of new treatments.
The research, published in the Proceedings of the National Academy of Sciences of the USA, shows the major locations of cholesterol in the brain and what molecules it can be converted to.
Plants produce the hormone jasmonic acid as a defence response when challenged. This is how they ensure that their predators no longer like the taste of their leaves. Biologists want to find out whether biological precursors and other variants of jasmonic acid lead to similar or different effects. But such derivatives of the hormone have so far been too expensive for experiments and difficult to come by.
A combination of genetic shuffling and evolutionary selection of near-identical genetic sequences among specific bat and pangolin coronaviruses may have led to the evolution of SARS-CoV-2 and its introduction into humans, a new study suggests. The results also showed that the virus' entire receptor binding motif (RBM), a component that plays a key role in viral entry into host cells, was introduced through recombination with pangolin coronaviruses.
