EAST LANSING, Mich. - Some people are drawn to cologne; others are attracted to perfume. When it comes to sea lampreys, however, spermine smells like love.
In new research led by Michigan State University and published in the current issue of PLoS Biology, spermine, an odorous compound found in male semen, proved to be a powerful aphrodisiac.
BOSTON - A study led by researchers at Boston Medical Center (BMC) found that symptom-triggered medication dosing for neonatal opioid withdrawal syndrome instead of infants receiving a fixed schedule of medication with a long taper reduced the length of their hospital stay. The findings, published in Hospital Pediatrics, indicate that following the novel symptom-triggered approach - developed at BMC - for administering medication could be a more effective intervention for these infants and could help reduce unnecessary medication exposure.
Extremely premature infants who fail to grow as expected have delayed development of their microbiome, or communities of bacteria and other micro-organisms living in the gut, according to a new study published in Scientific Reports. Analysis of these infants' metabolism revealed that their bodies are responding as if they were fasting, despite caloric intake similar to extremely premature infants with appropriate growth.
PITTSBURGH (July 9, 2019) … A bioengineering group from the University of Pittsburgh Swanson School of Engineering is bringing the worlds of computational modeling and experimentation closer together by developing a methodology to help analyze the wealth
of imaging data provided by advancements in imaging tools and automated microscopes.
A chaotic household - one where things just don't seem to run smoothly, there's lots of noise, little gets taken care of in a timely manner, and where relaxation is difficult - as well as child and parent depression, are risk factors for worse asthma outcomes in urban minority children, according to a new paper published in the journal Pediatrics.
The role of Hox genes in changing the layout of different body parts during evolution has been challenged by a study led by researchers out of the University of Pittsburgh's Department of Biological Sciences.
Hox genes are vital to developing differences in repeated body parts such as vertebrae, limbs, or digits in most animal species, including human beings. Ever since their discovery, scientists have thought that modifications to Hox genes could be the primary way that the animal body plan has been altered during evolution.
HERSHEY, Pa. -- Atypical eating behaviors may be a sign a child should be screened for autism, according to a new study from Penn State College of Medicine.
Research by Susan Mayes, professor of psychiatry, found that atypical eating behaviors were present in 70% of children with autism, which is 15 times more common than in neurotypical children.
Atypical eating behaviors may include severely limited food preferences, hypersensitivity to food textures or temperatures, and pocketing food without swallowing.
Research results on drug-gene interactions are much less likely to be replicated if they are performed by hierarchical communities or close-knit groups of frequent collaborators who use similar methods, instead of independent groups of scientists using different methods, suggests a paper published last week in eLife.
The findings may help improve the reliability of scientific results by helping to identify possible factors that contribute to the publication of unreliable, misleading or false results about potential drug-gene interactions.
When anthropologists consider the origins of warfare, their evolutionary theories tend to boil it down to the resource-scarcity trifecta of food, territory and mates - three resources that would justify the loss of life and risk to a warring group of hunter-gatherers.
A deep learning-powered computational framework, 'DeepEC,' will allow the high-quality and high-throughput prediction of enzyme commission numbers, which is essential for the accurate understanding of enzyme functions.
A team of Dr. Jae Yong Ryu, Professor Hyun Uk Kim, and Distinguished Professor Sang Yup Lee at KAIST reported the computational framework powered by deep learning that predicts enzyme commission (EC) numbers with high precision in a high-throughput manner.
Dolomite is widely in the metal industry as a fireproof material and in construction, such as for joint grouting in panel building. Of course, dolomite is also known as a collector of hydrocarbons.
The immune system is indispensable for defense against invading pathogens, but its aberrant activation may lead to autoimmune diseases. Regulatory T cells play a crucial role in preventing excess immune activation; mice without enough Treg function develop autoimmune disorders and are susceptible to immune diseases.
Exactly how fast is the universe expanding?
Scientists are still not completely sure, but a Princeton-led team of astrophysicists has used the neutron star merger detected in 2017 to come up with a more precise value for this figure, known as the Hubble constant. Their work appears in the current issue of the journal Nature Astronomy.
Osaka, Japan -- A "vacuum" is generally thought to be nothing but empty space. But in fact, a vacuum is filled with "virtual particle-antiparticle pairs" of electrons and positrons that are continuously created and annihilated in unimaginably short time-scales.
Increasing development of micro-scale electronics has stimulated demand of the corresponding micro-scale power sources, especially for micro-batteries (MBs). However, complex manufacturing process and poor flexibility of the traditional stacked batteries have hindered their practical applications.
