New study identifies a bizarre new species suggesting that giant marine lizards thrived before the asteroid wiped them out 66 million years ago.
A new species of mosasaur - an ancient sea-going lizard from the age of dinosaurs - has been found with shark-like teeth that gave it a deadly slicing bite.
Clumsy kids can be as aerobically fit as their peers with better motor skills, a new Finnish study shows. The results are based on research conducted at the Faculty of Sport and Health Sciences of the University of Jyväskylä and the Institute of Biomedicine of the University of Eastern Finland, and they were published in Translational Sports Medicine.
Aerobic fitness doesn't go hand in hand with motor skills
FLAGSTAFF, Ariz. -- Jan. 19, 2021 -- The results of a study led by Northern Arizona University and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest the immune systems of people infected with COVID-19 may rely on antibodies created during infections from earlier coronaviruses to help fight the disease.
Researchers looked at neurons within the basal ganglia, a part of the brain that, when damaged, can severely impact a person's motor ability, making seemingly simple reaching-and-grasping tasks near impossible
They focused on a large group of neurons, which has two distinct types - D1 direct striatal output neurons and D2 indirect output neurons
These neurons are implicated in the development of Parkinson's and Huntington's - neurodegenerative diseases that result in the progressive degeneration or death of nerve cells
Researchers have used the world's smallest, smartphone-sized DNA sequencing device to monitor hundreds of different bacteria in a river ecosystem.
Writing in the journal eLife, the interdisciplinary team from the University of Cambridge, UK, provide practical and analytical guidelines for using the device, called the MinION (from Oxford Nanopore Technologies), to monitor freshwater health. Their guidelines promise a significantly more cost-effective and simple approach to this work outside the lab, compared to existing methods.
A new negative pressure ventilator which could provide additional treatment options for patients with respiratory failure, including those with COVID-19 - and whose design can be easily adapted to developing countries - has been created by a team that includes anaesthetists, nurses and engineers. Details on the new exovent system - which is similar in design but much smaller in scale and easier to use than the devices used to help treat polio patients during the 1950s - are published in Anaesthesia (a journal of the Association of Anaesthetists).
Nearly 78 per cent of children with autism have at least one mental health condition and nearly half have two mental health conditions or more, according to a new U.S. study from the University of British Columbia's department of psychology and the AJ Drexel Autism Institute at Drexel University (Pennsylvania).
The study also found mental health conditions present in 44.8 per cent of pre-school age children with autism. The scope of the issue among that age group had not previously been established using a large, population-based sample.
Malta, a sovereign microstate in the middle of the Mediterranean Sea, has no shortage of sunny beaches, honey-bricked villages and rugged countryside. Beyond its Mediterranean charm, Malta is home to a geographically and culturally isolated population whose unique genetic makeup, makes this island nation a goldmine for genetics research.
With the global student community taking online courses as a result of the anti-Covid-19 measures, a study led by the University of Geneva (UNIGE) reveals that online courses deepen inequalities between gifted and less gifted students by 5%. The results of the study, which was based on data collected in 2016-2017 prior to the anti-Covid lockdown initiatives, are published in the Journal of the European Economic Association. They indicate that this learning gap between different student profiles is mainly due to their behaviour and motivation.
A new study by researchers from Chulalongkorn University, Tohoku University, and The George Washington University is the first to identify autism candidate genes that may be responsible for the sex-specific effects of bisphenol A (BPA) on the brain. It suggests BPA may serve as an environmental factor that contributes to the prevalence of male bias in autism spectrum disorder (ASD).
The research was published in the journal Scientific Reports.
The survival of pesky little flies in showers and other wet areas around the house, impervious to water droplets that may be larger than they are, comes down to more than quick reflexes. The insects have evolved a unique coating of hairs that allows them to shrug off water droplets of almost any size, KAUST researchers have shown.
A Tokyo Tech research team led by Specially Appointed Professor Takuya Oda of the Institute of Innovative Research and Professor Keisuke Tanaka of the School of Computing, in collaboration with Mitsubishi Electric Corporation, has developed a new technology an original blockchain[1] technology that can optimize peer-to-peer (P2P) energy trading[2].
People with anxiety and depression are more likely to report an increase in drinking during the COVID-19 pandemic than those without mental health issues, according to a new study by researchers at NYU School of Global Public Health published in the journal Preventive Medicine. While drinking grew the most among younger people, older adults with anxiety and depression saw a sharper increase in their risk for harmful alcohol use.
Genetic rewiring could have driven an evolutionary explosion in the shapes, sizes and adaptations of cichlid fish, in East Africa's answer to Darwin's Galapagos finches.
Fear of losing your job, worrying about you or a loved one getting sick, and online meetups with family and friends you have not seen for months. The COVID-19 lockdown has completely changed everyday life for most people around the world. Physical distancing is the new normal and an extremely important tool in the fight against the pandemic.
