USDA-ARS releases genome of the voracious desert locust
Reports and Proceedings
The first high-quality genome of the desert locust—those voracious feeders of plague and devastation infamy and the most destructive migratory insect in the world—has been produced by U.S. Department of Agriculture Agricultural Research Service scientists. The genome of the desert locust (Schistocerca gregaria) is enormous at just under 9 billion base pairs, nearly three times the size of the human genome. The size of the desert locust’s chromosomes is remarkable; compare them to those of the model fruit fly Drosophila melanogaster, the first insect genome ever assembled. Many of the desert locust’s individual chromosomes are larger than the entire fruit fly genome. Next to the fruit fly, it’s like an 18-wheeler next to a compact car.
Overall, the study identified 67.7% of stroke patients with previously undiagnosed major risk factors were found to have one major risk factor
Alexandria, VA, USA, June 17, 2022 – A study investigating the role of Treponema denticola (T. denticola) in Alzheimer’s disease (AD) pathogenesis will be presented by Zhiqun Tang of the West China Hospital of Stomatology at Sichuan University, China at the 100th General Session and Exhibition of the IADR, to be held in conjunction with the 5th Meeting of the IADR Asia Pacific Region. The Interactive Talk presentation, “Treponema Denticola Induces Alzheimer-like Tau Hyperphosphorylation in Mice”, will take place on Saturday, June 25th, 2022 at 11 a.m. China Standard Time (UTC+08:00) during the “Biological Impact of Ageing” session.
The work, led by Johns Hopkins University, the Georgia Institute of Technology, and University of Washington researchers, is believed to be the first to show that robots loaded with an accepted and widely used model operate with significant gender and racial biases. The work is set to be presented and published this week at the 2022 Conference on Fairness, Accountability, and Transparency.
Patients with a paediatric onset immune-mediated inflammatory disease (pIMID) have a significantly higher risk of premature death, according to new research being presented today at the 54th Annual Meeting of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN).
The study, which analysed the health records of over half of the Danish population, found that those who had tested positive for COVID-19 were at an increased risk of Alzheimer’s disease, Parkinson’s disease, and ischaemic stroke.
A new low-loss transmitter allows higher precision low-orbit satellite earth monitoring, according to a study by Tokyo Tech researchers. The novel transmitter works in the Ka band of the microwave frequency spectrum, where no efficient transmission has been possible so far. By using circularly polarized signal, and an innovative internal calibration scheme, efficient transmission with low signal noise and wide-angle scanning is demonstrated.
The Webb team has now approved 10 out of 17 science instrument modes; since last week we added (14) MIRI imaging, (2) NIRCam wide-field slitless spectroscopy, and our final NIRISS mode, (10) single-object slitless spectroscopy. As we ramp down the final commissioning activities, some openings in the schedule have appeared. The team has started to take some of the first science data, getting it ready to release starting July 12, 2022, which will mark the official end of commissioning Webb and the start of routine science operations.
Astronomers discovered a rocket body heading toward a lunar collision late last year. Impact occurred March 4, with NASA's Lunar Reconnaissance Orbiter later spotting the resulting crater. Surprisingly the crater is actually two craters, an eastern crater (18-meter diameter, about 19.5 yards) superimposed on a western crater (16-meter diameter, about 17.5 yards).
Researchers at The University of Texas at San Antonio (UTSA) today released “Economic Contributions of Distilled Spirits in Texas 2020,” a new study highlighting the significant economic impact Texas distillers made to their local communities and the state in 2020, despite economic hardships of the pandemic and lingering Prohibition-era laws restricting sales.
Alexandria, VA, USA, June 17, 2022 – A study investigating the relationship between free sugar intake in early childhood and dental caries at age four to six years will be presented by Stephanie Heitkonig of Royal Children's Hospital, Murdoch Children’s Research Institute and the University of Melbourne, Australia at the 100th General Session and Exhibition of the IADR, to be held in conjunction with the 5th Meeting of the IADR Asia Pacific Region. The Interactive Talk presentation, “The Influence of Dietary Free Sugar Intake on Dental Caries”, will take place on Thursday, June 23rd, 2022 at 8 p.m. China Standard Time (UTC+08:00) during the “Behavioral and Social Risk Factors Associated with Early Childhood Caries” session.
Researchers from the Universidad Carlos III de Madrid (UC3M) and the Universidad Complutense de Madrid (UCM) have designed and patented a new device for carrying out knee rehabilitation and strengthening exercises.
