ITHACA, N.Y. - For the first time, Cornell University researchers have developed a technique for studying the neuroscience of motor control in mice ¬- by focusing on a mouse's tongue when it licks a water spout.
The technique incorporates high-speed cameras and machine learning in a tractable experimental setup that opens the door for revealing mysteries of how the motor cortex works, understanding the neural basis of related disorders like Parkinson's disease, and informing robots.
Open up Scott Roy's Twitter bio and you'll see a simple but revealing sentence: "The more I learn the more I'm confused." Now the rest of the scientific world can share in his confusion. The San Francisco State University associate professor of Biology's most recent research, published earlier this month in one of the scientific world's most prestigious journals, catalogues a strange and confounding system of genes in a tiny rodent that scientists have ignored for decades.
Scanning technology aimed at detecting small amounts of nuclear materials was unveiled by scientists in Sweden today, with the hope of preventing acts of nuclear terrorism.
Bo Cederwall, a professor of physics at KTH Royal Institute of Technology, says the technology can be used in airports and seaports for routine inspection of passengers and goods. The research is published and featured in the journals Science Advances and Science, respectively.
Despite expert recommendations that children continue to get regularly scheduled vaccines during the pandemic, vaccination rates have decreased in several states.
Nearly two thirds (61%) expressed concern about their worsening mood in Lockdown and associated restrictions1.
34% said they felt more anxious and 28% felt more depressed during Lockdown and associated restrictions1.
Coffee helped lift nearly half (44%) of adult's negative moods in Lockdown and associated restrictions1.
Monash University researchers have engineered new antimicrobial surfaces that can significantly reduce the formation of bacteria on medical instruments, such as urinary catheters, and reduce the risk of patient infection while in hospital.
This world-first study demonstrates the potential for 3D engineered surfaces in preventing the initial formation of microcolonies of Escherichiacoli (E.coli), Klebsiellapneumoniae and Pseudomonas aeruginosa - the three most common urinary tract bacterial infections (UTIs) associated with catheters.
A new survey study suggests that, for adolescents who received unplanned distance education due to the COVID-19 pandemic, experiencing one's own competence was linked to positive emotion, self-motivation to learn, and pro-learning behaviors. Feeling connected to others was also linked to positive emotion. Julia Holzer of the University of Vienna, Austria, and colleagues present these findings in the open-access journal PLOS ONE.
Almost 1 in 4 COVID-19 patients have another bacterial, viral or fungal infection simultaneously or subsequently, with such patients experiencing worse disease outcomes.
Tsukuba, Japan - Autoimmune diseases occur when an individual's immune system fights their own body as if it was a foreign invader. However, in healthy people, these responses are prevented by a process known as immune tolerance. Many complex biological mechanisms maintain the necessary balance between immune activation and suppression to ensure immune tolerance does not prevent the body from effectively fighting pathogens.
Recently published in the scientific journal Brain Communications, a new study distinguished structural patterns between individuals with corpus callosum dysgenesis (CCD), a congenital condition that consists of the absence or incomplete development in the connecting structure between the two brain hemispheres. The research was carried out by the D'Or Institute for Research and Education (IDOR), the University of Pittsburgh, Oswaldo Cruz Foundation (Fiocruz), and the Federal University of Rio de Janeiro (UFRJ).
Philadelphia, May 18, 2021 - Many socioeconomically disadvantaged children face poor cognitive and mental health outcomes, and researchers are working to determine the specific factors that link childhood conditions to those poor outcomes, including how they might shape brain circuitry. In a new study, researchers have examined how "neighborhood disadvantage" can affect the developing brain, including the brain's connectivity between regions.
EUGENE, Ore. -- May 19, 2021 -- High-resolution imaging of fruit flies at the University of Oregon has captured mechanical motions that stem cells use to make neurons, the cells that make up the brain.
These motions coordinate cell division with differentiation, where newly born cells become neurons. Differentiation is essential for building the brain circuitry in complex organisms that underlies human cognition and emotions, said Ken Prehoda, a professor in the UO's Department of Chemistry and Biochemistry.
WASHINGTON, DC (May 19, 2021) - Human genetics and genomics contributed $265 billion to the U.S. economy in 2019 and has the potential to drive significant further growth given major new areas of application, according to a new report issued today by the American Society of Human Genetics (ASHG). The findings indicate that this research and industry sector has seen its annual impact on the U.S.
Chronic exposure to second-hand smoke results in lower body weight and cognitive impairments that more profoundly affects males, according to new research in mice led by Oregon Health & Science University.
The study published today in the journal Environmental Health Perspectives.
An international research team led by Professor Charles Gauthier from the Institut national de la recherche scientifique (INRS) has discovered a new molecule with potential to revolutionize the biosurfactant market.
