Feb 7 2019 Chemical and topographical single-cell imaging at nanoscale resolution by near-field desorption mass spectrometry How are chemicals distributed in a cell? Chinese scientists have developed a combined mass spectrometry and biological imaging device that enables direct, label-free detection, and high-resolution mapping of chemicals inside a biological cell. As demonstrated in their publication in […]Continue Reading ...
Long before human ancestors began hunting large mammals for meat, a fatty diet provided them with the nutrition to develop bigger brains, posits a new paper in Current Anthropology. The paper argues that our early ancestors acquired a taste for fat by eating marrow scavenged from the skeletal remains of large animals that had been […]Continue Reading ...
Research team receives start-up funding to develop first-of-its-kind motorized medical brace A team of researchers from the University of Delaware has received nearly $200,000 in start-up funding to develop a motorized ankle foot device for children with cerebral palsy (CP) that includes a novel artificial muscle. The brace is the first lower extremity device designed […]Continue Reading ...
Scientists uncover how important enzymes in both fission yeast and human cancer cells interact to boost cell proliferation Much like shoelaces or dangly necklaces, DNA strands can tangle up in unruly knots. Specialized enzymes keep DNA organized when cells divide, so the cells split smoothly and don’t get stuck. But in tumor cells, this failsafe […]Continue Reading ...
A University of Kansas geologist’s work in the remote High Arctic of Norway has exposed the startling global spread of antibiotic-resistant microbes — including multidrug-resistant “superbugs” — that could have dire implications for human health worldwide. Jennifer Roberts, professor and chair of geology at KU, began by investigating the microbial geochemistry of thawing permafrost and […]Continue Reading ...
Feb 5 2019 Impulsiveness and substance use share a genetic basis, according to genome-wide association studies published in JNeurosci by academic and industry researchers. With more than 20,000 participants, the research represents the largest genetic analysis of impulsive personality traits to date. Manhattan plot of GWAS results indicating the strongest associations between the 22 autosomes, […]Continue Reading ...
Placebo effects do not only occur in medical treatment – placebos can also work when psychological effects are attributed to them. Researchers from the University of Basel’s Faculty of Psychology reported these findings in the journal Scientific Reports, based on three studies with over 400 participants. Psychotherapy and placebos are both psychological interventions that not […]Continue Reading ...
If you’re going to choose dessert first, then the high-calorie option might lead to your eating a healthier meal, unless you have a lot on your mind, according to new research published by the American Psychological Association. Researchers placed either a healthy or less healthy dessert (fresh fruit vs. lemon cheesecake) at the beginning or […]Continue Reading ...
New research reveals RNAs, which are crucial for cells to produce proteins, are also involved in protein aggregation, where proteins do not fold properly and ‘clump’ together into aggregates. If cells cannot clear these away, they become toxic and prevent cells working properly. This discovery, led by scientists at the Centre for Genomic Regulation (CRG) […]Continue Reading ...
The ALS Association and The Tow Foundation are pleased to announce their continuing support of the New York Genome Center’s (NYGC) Center for Genomics of Neurodegenerative Disease (CGND), in recognition of the substantial genomic research being carried out by NYGC scientists. The ALS Association has committed an additional $3.5 million to the NYGC’s CGND, including […]Continue Reading ...
A study produced by researchers of the Universitat de València specifies what the care work consists of and what the different delivery systems are. In addition, it concludes that the working conditions of the auxiliary personnel of the Home Help Service (SAD, in Spanish) are better when the service is publicly owned and also that […]Continue Reading ...
Search for a description of “p53” and it becomes clear that this human protein is widely known for its cancer-fighting benefits, leading to its renown as “the guardian of the genome.” Scientists at the University of California San Diego have published a new study challenging that description. Studying the “wild type” version of p53 (WTp53), […]Continue Reading ...
Signaling through interleukin-10 (IL-10) receptors on gut immune cells plays a critical role in protecting the gut lining and microbiota from disruption caused by whipworms, according to a study published January 31 in the open-access journal PLOS Pathogens by María Duque-Correa of the Wellcome Sanger Institute in the UK, and colleagues. The human gut is […]Continue Reading ...
In a comprehensive analysis, SSRIs found to be most effective in treating children and adolescents with anxiety disorder Researchers from the University of Cincinnati (UC) examined common medications prescribed for children and adolescents with anxiety disorders, to determine which are the most effective and best-tolerated. This study revealed that the selective serotonin reuptake inhibitors (SSRIs) […]Continue Reading ...
