Researchers at Karolinska Institutet in Sweden have, together with colleagues from Aalto University in Finland, developed a new method for creating images of molecules in cells or tissue samples. The method is based on the use of DNA snippets and is called DNA microscopy. The approach is currently described in the scientific journal PNAS.
In the steamy, often filthy world of the humble house fly, (the Musca domestica) clear division exists among the males of the species. Though not a civil war, there are differences, to be sure, between males in the north and those that hail from the south. Finding out why those differences appear in the genetic sequences of the northerners and southerners is key to understanding nothing less than sex determination, but there is an essential paradox: The genetic difference is trivial.
According to a new study published in Current Anthropology, an extreme ritual involving bodily mutilation has no detectable long-term harmful effects on participants and actually has a positive effect on psychological well-being.
A new language-skills study that included infants later diagnosed with autism suggests that all children can benefit from exposure to more speech from their caregivers.
INFORMS Journal Management Science New Study Key Takeaways:
A combination of the donor-priority rule and freeze-period prove successful for increasing quality organ donations by 12.8%.
Choosing the appropriate freeze length can mitigate the number of low-quality organs, a problem that arises as a result of only using the donor-priority rule.
Healthy organs can increase patient life expectancy by 18 years at a value of $50,000 a year.
AURORA, Colo. (Sept. 4, 2019) - A new study led by scientists from the University of Colorado School of Medicine offers insight into the mechanism of a key cellular process.
Scientists at the University of Oxford have developed new artificial intelligence software to recognise and track the faces of individual chimpanzees in the wild. The new software will allow researchers and wildlife conservationists to significantly cut back on time and resources spent analysing video footage, according to the new paper published today in Science Advances.
Bottom Line: About 400 caregivers reported pain medication use by children after common surgeries such as hernia, elbow fracture, appendectomy or adenoid removal in this study. Most reported using acetaminophen or ibuprofen or both; 88 patients (22%) were prescribed an opioid at hospital discharge and most used less than prescribed. The lack of an opioid prescription wasn't associated with poor pain control, a postdischarge opioid prescription or a pain-related visit to an emergency department for patients.
Bottom Line: This analysis reports black, Hispanic and American Indian or Alaska Native students remain underrepresented in allopathic medical schools when compared with the U.S. population, despite new diversity accreditation guidelines. The study used self-reported data on race/ethnicity and sex for medical school applicants and enrolled students (matriculants) from 2002 to 2017. New diversity accreditation guidelines were instituted in 2009 by the Liaison Committee on Medical Education.
We decided to examine the state of prosecutor funding and caseloads after recent local debates on the issue. Prosecutors contend they need more staff to ensure due process and increased diversion options and others are concerned that doing so would reverse justice reform efforts, under the assumption that more prosecutors equate to more convictions. As a result, we, the Center for Justice Research (CJR), have released a research brief comparing the budgets, caseloads and staffing levels of the country's largest county prosecutor offices.
Studies have suggested that the contrast between the white of human eyes - known as the sclerae - and the colourful irises allows others to detect the direction of our gaze. The ability to detect gaze is important as many other human skills, such as social learning, seem to depend on this.
In contrast, as the sclerae of apes' eyes is often darker than human eyes, researchers have long argued that their gaze is 'cryptic', or hidden. This means that nonhuman apes would not be able to see where other members of their species are looking.
Scientists have discovered that a receptor on the surface of brain cells plays a key role in regulating how both animals and people respond to stress. The research suggests that the receptor may represent an important biomarker of post-traumatic stress disorder (PTSD) in humans and may offer a new target for future, more effective treatments for stress and anxiety.
A new beaked whale species Berardius minimus, which has been long postulated by local whalers in Hokkaido, Japan, has been confirmed.
In a collaboration between the National Museum of Nature and Science, Hokkaido University, Iwate University, and the United States National Museum of Natural History, a beaked whale species which has long been called Kurotsuchikujira (black Baird's beaked whale) by local Hokkaido whalers has been confirmed as the new cetacean species Berardius minimus (B. minimus).
Scientists at Linköping University have shown how a quantum computer really works and have managed to simulate quantum computer properties in a classical computer. "Our results should be highly significant in determining how to build quantum computers", says Professor Jan-Åke Larsson.
Male turkeys famously will attempt to mate with a head on a stick. In fact, gobblers prize a snug snood over the whole hen. How far then can a man's ideal sexual partner be stripped?
