CHAMPAIGN, Ill. -- Two brain-signaling molecules control how anemonefish dads care for their young and respond to nest intruders, researchers report in a new study. Because there are many similarities in brain structure between fish and humans, the findings offer insight into the fundamental nature of parental care, the scientists say.
Scientists from the University of Sheffield have discovered a pulsating ancient star in a double star system, which will allow them to access important information on the history of how stars like our Sun evolve and eventually die.
The discovery of the first ever pulsating white dwarf star in an eclipsing binary by physicists at Sheffield means the team can see how binary evolution has affected the internal structure of a white dwarf in detail for the first time.
A good indicator of dysregulation in live cells is a change in their RNA expression. MicroRNA (miRNA), a special type of RNA, is considered a biomarker for carcinogenic cells. A team of scientists from China has found a way to amplify miRNA in live tumor cells for bioimaging. As they report in the journal Angewandte Chemie, their assay is based on a robust cellular autocatalytic biocircuit triggered by synthetic DNA and nanoparticles.
(New York, March 16) A new CUNY Graduate School of Public Health and Health Policy (CUNY SPH) survey released today found that 60% of New York State residents believe their chances of contracting the novel Coronavirus are low or very low. The survey of 1000 New York households, conducted between March 13-15, 2020 and considered accurate within a range of 3%, also found that more than half (55%) of all respondents live in households with one or more members over age 60, the highest risk age group for Coronavirus infection.
Toxic personality is a term used to describe people who behave greedily, immodestly and unfairly and take the truth very lightly. Dr. Mareike Kholin, Bastian Kückelhaus and Prof. Dr. Gerhard Blickle from the Department of Psychology at the University of Bonn found out why such people can still succeed in their careers. The trick that leads to the top is social skill. The results are presented online in advance in the journal "Personality and Individual Differences". The print version will be published in April.
KNOXVILLE --The best bargains for conserving some of the world's most vulnerable salamanders and other vertebrate species can be found in Central Texas and the Appalachians, according to new conservation tools developed at the National Institute for Mathematical and Biological Synthesis (NIMBioS) at the University of Tennessee, Knoxville.
The study involves a suite of computer algorithms that surf across many different kinds of data to create maps of top priorities and projections of what species would benefit the most from increases in conservation dollars.
Crick and Imperial researchers have found that a key antibiotic widely used to treat drug-resistant tuberculosis does not work as expected - a finding which could be used to develop new drugs. The study was part-funded by the Francis Crick Institute and the Wellcome Trust.
Philadelphia, March 16, 2020 - An e-cigarette carried in the left breast shirt pocket of a patient with an implantable cardioverter-defibrillator (ICD) caused magnetic reversion, interrupting the ICD's ability to detect and treat dangerous heart rhythm problems, clinicians report in HeartRhythm Case Reports, published by Elsevier.
Finally, some good news has emerged about the novel coronavirus that has spread to about 50 countries across the world. Chinese professors report in the journal Frontiers in Pediatrics that it doesn't appear that the viral infection is transmittable from pregnant mothers to newborns at birth.
ANN ARBOR, Mich. -- Experts recommend starting conversations about inappropriate touching during the preschool years, but less than half of parents of preschoolers in a national poll say they've begun that discussion.
Meanwhile, one in four parents of elementary school-age children say they have not yet begun talking about inappropriate touching, according to the C.S. Mott Children's Hospital National Poll on Children's Health at the University of Michigan.
The report is based on responses from 1,106 parents who had at least one child age 2-9 years.
A unique rock carving found in the Teymareh rock art site (Khomein county) in Central Iran with six limbs has been described as part man, part mantis. Rock carvings, or petroglyphs, of invertebrate animals are rare, so entomologists teamed up with archaeologists to try and identify the motif. They compared the carving with others around the world and with the local six-legged creatures which its prehistoric artists could have encountered.
Tokyo, Japan - Scientists from Tokyo Metropolitan University have discovered that Drosophila flies lose long-term memory (LTM) of a traumatic event when kept in the dark, the first confirmation of environmental light playing a role in LTM maintenance. The team also identified the specific molecular mechanism responsible for this effect. LTMs are notoriously difficult to erase; this work may lead to novel treatments for sufferers of trauma, perhaps even the erasure of life-altering traumatic memories.
Individuals with Down syndrome are at a much greater risk of developing Alzheimer's disease, with inflammation of the brain starting early in life and the risk of Alzheimer's reaching nearly 80% by the age of 60.
The root cause of Alzheimer's disease is unknown. However, its frequency in patients with Down syndrome suggests that targeting inflammation in preclinical models of that syndrome could be an attractive strategy for designing therapies to promote healthier aging.

Study results call into question the utility of testing blood pressure load--the proportion of elevated blood pressure readings detected over 24 hours--for diagnosing hypertension in children.
Washington, DC -- Results from a new study provide insights on evaluating high blood pressure in children. The findings appear in an upcoming issue of CJASN.
Microbiologists have long adopted the language of human settlement to describe how bacteria live and grow: They "invade" and "colonize." Relations dwelling in close proximity are "colonies."
