Intravenous injection of bone marrow derived stem cells (MSCs) in patients with spinal cord injuries led to significant improvement in motor functions, researchers from Yale University and Japan report Feb. 18 in the Journal of Clinical Neurology and Neurosurgery.
For more than half of the patients, substantial improvements in key functions -- such as ability to walk, or to use their hands -- were observed within weeks of stem cell injection, the researchers report. No substantial side effects were reported.
ITHACA, N.Y. - In the same way that Lego pieces can be arranged in new ways to build a variety of structures, genetic elements can be mixed and matched to create new genes, according to new research.
A long-proposed mechanism for creating genes, called exon shuffling, works by shuffling functional blocks of DNA sequences into new genes that express proteins.
ITHACA, N.Y. - A new study identifies a mechanism that makes bacteria tolerant to penicillin and related antibiotics, findings that could lead to new therapies that boost the effectiveness of these treatments.
Antibiotic tolerance is the ability of bacteria to survive exposure to antibiotics, in contrast to antibiotic resistance, when bacteria actually grow in the presence of antibiotics. Tolerant bacteria can lead to infections that persist after treatment and may develop into resistance over time.
COLUMBIA, Mo. -- When teachers encounter disruptive or noncompliant students in the classroom, they typically respond by focusing on the negative behavior. However, new research from the University of Missouri found that offering students more positive encouragement not only reduces disruptive classroom behavior, but can improve students' academic and social outcomes.
When you slip into sleep, it's easy to imagine that your brain shuts down, but University of Michigan research suggests that groups of neurons activated during prior learning keep humming, tattooing memories into your brain.
Abu Dhabi, UAE, February 22, 2021: Learning more about what motivates people to join violent ideological groups and engage in acts of cruelty against others is of great social and societal importance. New research from Assistant Professor of Psychology at NYUAD Jocelyn Bélanger explores the idea of ideological obsession as a form of addictive behavior that is central to understanding why people ultimately engage in ideological violence, and how best to help them break this addiction.
Establishing a consistent sleep schedule for a toddler can be one of the most challenging aspects of child rearing, but it also may be one of the most important.
Research findings from a team including Lauren Covington, an assistant professor in the University of Delaware School of Nursing, suggest that children with inconsistent sleep schedules have higher body mass index (BMI) percentiles. Their findings, published in the Annals of Behavioral Medicine, suggest sleep could help explain the association between household poverty and BMI.
LOGAN, UTAH, USA -- You might not like mosquitoes, but they like you, says Utah State University biologist Norah Saarman. And where you lead, they will follow.
In addition to annoying bites and buzzing, some mosquitoes carry harmful diseases. Aedes aegypti, the so-called Yellow Fever mosquito and the subject of a recent study by Saarman and colleagues, is the primary vector for transmission of viruses causing dengue fever, chikungunya and Zika, as well as yellow fever, in humans.
The cover for issue 46 of Oncotarget features Figure 6, "Establishment of a SARS-CoV-2 pseudovirus that expresses SPIKE protein variants on the envelope of a lentiviral core, infection of human airway epithelial cells or lung cancer cells, and demonstration of MEKi attenuation of infectivity on primary human cells," published in "MEK inhibitors reduce cellular expression of ACE2, pERK, pRb while stimulating NK-mediated cytotoxicity and attenuating inflammatory cy
In a new study out of University of California San Diego School of Medicine, researchers have identified a universal strain of bacteria derived from healthy human skin that can treat the most common type of eczema, also known as atopic dermatitis.
The diversity and numbers of wild salmon in Northern B.C. have declined approximately 70 per cent over the past century, according to a new Simon Fraser University study.
Researchers drawing on 100-year-old salmon scales report that recent numbers of wild adult sockeye salmon returning to the Skeena River are 70 per cent lower than 100 years ago. Wild salmon diversity in the Skeena watershed has similarly declined by 70 per cent over the last century.
Boston, Mass. - Even with more than 1.5 million Americans receiving a COVID vaccine each day, officials estimate it will take many more months before enough people are protected from the deadly virus. Until then, and potentially beyond, experts agree that opening up schools, restaurants and other public places as safely as possible will rely on widespread testing for SARS-CoV-2, the virus that causes COVID-19.
ITHACA, N.Y. - Cornell University scientists have identified a new contender when it comes to quantum materials for computing and low-temperature electronics.
Using nitride-based materials, the researchers created a material structure that simultaneously exhibits superconductivity - in which electrical resistance vanishes completely - and the quantum Hall effect, which produces resistance with extreme precision when a magnetic field is applied.
LOS ALAMOS, N.M., Feb. 22, 2021--A team of quantum theorists seeking to cure a basic problem with quantum annealing computers--they have to run at a relatively slow pace to operate properly--found something intriguing instead. While probing how quantum annealers perform when operated faster than desired, the team unexpectedly discovered a new effect that may account for the imbalanced distribution of matter and antimatter in the universe and a novel approach to separating isotopes.
HOUSTON - (Feb. 22, 2021) - Governments with strong female representation are more likely to deliver on campaign promises, according to new research from Rice University.
"The Effects of Women's Descriptive Representation on Government Behavior" by author Jonathan Homola, an assistant professor of political science at Rice, examines campaign promises and subsequent policymaking by parties in power in 10 European countries, the United States and Canada along with data on women in party leadership and elected offices.
