Examining sex differences in autism heritability

JAMA Psychiatry

2024-04-17

(Press-News.org) About The Study: The findings of this study including more than 1 million Swedish children suggest that the degree of phenotypic variation attributable to genetic differences (heritability) differs between males and females, indicating that some of the underlying causes of the condition may differ between the two sexes. The skewed sex ratio in autism spectrum disorder may be partly explained by differences in genetic variance between the sexes.

Authors: Benjamin H.K. Yip, Ph.D., of the Chinese University of Hong Kong, and Sven Sandin, Ph.D., of the Karolinska Institutet in Stockholm, are the corresponding authors.

38 trillion dollars in damages each year: World economy already committed to income reduction of 19 % due to climate change

2024-04-17

“Strong income reductions are projected for the majority of regions, including North America and Europe, with South Asia and Africa being most strongly affected. These are caused by the impact of climate change on various aspects that are relevant for economic growth such as agricultural yields, labour productivity or infrastructure,” says PIK scientist and first author of the study Maximilian Kotz. Overall, global annual damages are estimated to be at 38 trillion dollars, with a likely range of 19-59 trillion dollars in 2050. These damages mainly result from rising temperatures but also from changes ...

Genetic variant identified that shaped the human skull base

2024-04-17

Researchers from Tokyo Medical and Dental University (TMDU) and the Universities of Helsinki and Barcelona have identified a single nucleotide change key in the evolution of human skull morphology, affecting TBX1 gene expression and skull base development Tokyo, Japan – Humans, Homo sapiens, have unique features compared with other closely related hominin species and primates, including the shape of the base of the skull. The evolutionary changes underlying these features were significant in allowing the evolution ...

Deeper sedation may help find difficult-to-detect polyps during colonoscopy

2024-04-17

In patients undergoing colonoscopy to screen for colorectal cancer, deeper sedation using the anesthetic drug propofol may improve detection of "serrated" polyps — a type of precancerous lesion that can be difficult to detect, reports a study in the Online First edition of Anesthesiology, the peer-reviewed journal of the American Society of Anesthesiologists (ASA). "Our study provides the first evidence that monitored anesthesia care with propofol might increase detection of serrated polyps, which are more likely to be missed than adenomatous polyps during colonoscopy," said lead author ...

Virtual-dimension increase of EMG signals for prosthetic hands gesture recognition

2024-04-17

The electromyographic(EMG) signal is the bioelectrical current generated during muscle contraction. It can be transmitted as an input signal to an intelligent bionic prosthetic hand to control hand movements. By increasing the number of signal acquisition channels, richer information about the intention of the action can be captured, thus improving the success rate of the recognition of the intention of the action. However, it is not better to have more acquisition channels. As the number of channels increases, the hardware system becomes more complex, and the effect of improving the accuracy of gesture recognition gradually ...

Magneto-pneumatic hybrid-driven soft actuator with bidirectional torsion

2024-04-17

The ability of the human wrist to rotate around the forearm axis in 2 directions is crucial for many daily activities. This rotation, limited to a range of approximately [-90°, 90°], restricts the wrist's capacity to execute complex operational tasks. For example, when we open or lock a door with a key, our wrist performs a large rotational movement. When we screw, the wrist needs to twist 180° several times. However, due to the limited rotation angle, the hand needs to leave the key or screwdriver several times to complete the entire work process. In order to realize large rotation ratio in a single actuator, a research team from Zhejiang ...

One million US dollars for mapping the “springs of the spinal fluid”

2024-04-17

A research team at DZNE has been awarded around one million US dollars for the development of an innovative, AI-based method to measure the “choroid plexus” three-dimensionally in human brain scans. These finely branched brain structures are the main sources of the “cerebrospinal fluid” and thus of great significance for the function of the brain and spinal cord. It is also assumed that they play a role in various neurological diseases, including Alzheimer’s. The research project is funded by the US National Institutes of Health (NIH). The “cerebrospinal fluid” (CSF) is ...

Challenges in Greenland marine research and insights and priorities for development of East Greenland marine and coastal environments

2024-04-17

This report presents gained knowledge identified at two events during the Greenland Science Week on the 7th of November 2023 in Nuuk, Greenland: The 1st Biennial Greenland Marine Research Seminar and The workshop on Status and Development for East Greenland Waters Both events had a forward-looking focus, to gain insight and knowledge from stakeholders and other parties, to be implemented in future research. The marine research seminar also served as a follow-up on earlier ECOTIP and Face-It stakeholder involvement in Greenland and was an opportunity to share project results and recommendations ...

Copper beads in pig feed reshape swine gut microbiome

2024-04-17

Highlights: In lab experiments, copper shows antimicrobial properties, including against pathogens like Salmonella. Copper beads in animal feeds may improve gut health in pigs. A new bead design effectively delivers copper to the lower intestine. New findings show copper beads influence the microbial makeup in a pig’s gut, but more work is needed to optimize the benefits. Washington, D.C. — April 17, 2024 — Copper is a natural antimicrobial material that, when added to pig feed, may promote the growth and ...

FAU Engineering selected by NASA for University Nanosatellite Program

2024-04-17

Florida Atlantic University’s College of Engineering and Computer Science is among eight university teams in the United States selected to work with NASA and the U.S. military to foster innovation and expertise in the small satellite sector. NASA’s CubeSat Launch Initiative (CSLI) is partnering with the U.S. Air Force and U.S. Space Force for the 2024 Mission Concept Program. A CubeSat is among a class of research spacecraft called nanosatellites about the size of a 4-inch cube and typically weighing less than 5 pounds. Running from May through August, the University Nanosatellite ...

Nursing resources affect hospital patient experience ratings

2024-04-17

Waltham — April 10, 2024 — The nursing work environment, nurse education, and staffing levels are independent factors affecting hospital scores on a key measure of patient-centered care – with significant implications for reimbursements, reports a study in Medical Care. The journal is published in the Lippincott portfolio by Wolters Kluwer. "Our results provide evidence-based guidance about which modifiable aspects of hospital nursing are likely to improve patient experience ratings," said Kathleen E. Fitzpatrick Rosenbaum, PhD, RN, CCRN, of Yale University. How do nursing factors affect HCAHPS ...
