Targeting the brain’s immune cells may help prevent or treat Alzheimer’s disease
A gene mutation linked to Alzheimer's disease alters a signaling pathway in certain immune cells of individuals with the disease, according to a new study. The team also found that blocking the pathway -- with a drug that's currently being tested in.....»»
Effectiveness of ointment that kills antibiotic-resistant bacteria shown
New research shows that use of a topical drug, called AB569, a combination of acidified nitrite and EDTA (or ethylenediaminetetraacetic acid) promotes killing of antibiotic-resistant bacteria while enhancing the healing of wounds in a variety of burn.....»»
Research reveals new evidence that sugary beverage tax impacts are sustainable, effective
Two new studies based in Seattle provide evidence that public policies to reduce consumption of added sugars through taxes on sugar-sweetened beverages are effective and sustainable......»»
Within an Antarctic sea squirt, scientists discover a bacterial species with promising anti-melanoma properties
Biologists have successfully traced a naturally-produced melanoma-fighting compound called 'palmerolide A' to its source: a microbe that resides within Synoicum adareanum, a species of ascidian common to the waters of Antarctica's Anvers Island archi.....»»
Researchers identify key RNA "gatekeeper" in gene expression, pointing to possible new drug targets
Researchers have identified the first non-coding RNA that controls formation of chromosome loops, which govern gene expression. Jpx RNA was previously thought to be involved only in X chromosome inactivation, a necessary step in development of female.....»»
High-speed holography of cells spots physical beacons of disease
Biomedical engineers have engineered a holographic system capable of imaging and analyzing tens of thousands of cells per minute to both discover and recognize signs of disease......»»
Discovery of a Stem-like T cell in type 1 diabetes holds potential for improving cancer immunotherapy
As an autoimmune disease, Type 1 diabetes raises important questions about immune cell activity that have broad implications for immunotherapy......»»
Biosensor barcodes identify, detail ‘chatting’ among cancer cells
Ever since the first barcode appeared on a pack of chewing gum in 1974, the now-ubiquitous system has enabled manufacturers, retailers and consumers to quickly and effectively identify, characterize, locate and track products and materials. Scientist.....»»
Unorthodox "exercise in a pill" could offer simple solution for at-risk patients
Unique molecular signals in the body sent to our brain and potentially our eyes immediately after we exercise could be key to helping scientists 'bottle up' the benefits of exercise in a pill for at-risk patients......»»
Parental stress is a contributing factor linking maternal depression to child anxiety and depressive symptoms
A secondary analysis of the Fragile Families and Child Wellbeing Study (Fragile Families) found a bi-directional relationship where a mother's mental health symptoms impacted the child's mental health symptoms and vice versa, according to researchers.....»»
Footprints from site a at Laetoli, Tanzania, are from early humans, not bears
The oldest unequivocal evidence of upright walking in the human lineage are footprints discovered at Laetoli, Tanzania in 1978, by paleontologist Mary Leakey and her team. The bipedal trackways date to 3.7 million years ago. Another set of mysterious.....»»
The diabetes medication that could revolutionize heart failure treatment
A medication originally used for patients with diabetes is the first to help people with heart failure and could revolutionize treatment. Early research had shown that SGLT2 inhibitors could help around half of heart failure patients -- those with a.....»»
3D printing of blood plasma may speed up wound healing
New research suggests that effective wound healing may be aided by replicating a crucial component of our blood......»»
Successful treatment in mice for severe childhood cancer
In mice with high-risk neuroblastoma, tumors disappeared in response to a new combination treatment with precision medicines, a recent study shows. This is a vital step toward a potentially curative treatment for a form of cancer affecting young chil.....»»
Aerogels: Airy and efficient
Researchers have developed a new photocatalyst made from an aerogel that could enable more efficient hydrogen production. The key is sophisticated pretreatment of the material......»»
Breakthrough tool to show how much exoskeletons reduce back injury risk
A study reveals a breakthrough tool to assess the effect of exoskeletons on injury risk. The tool, called Exo-LiFFT, is an interactive calculator that will help companies looking for ways to overcome workforces struggling with musculoskeletal injurie.....»»
Cell types of the iris in mice
Researchers report they have genetically mapped the cell types that make up the mouse iris -- the thin disc of pigmented tissue that, in humans, gives eyes their distinct colors......»»
Study links high cholesterol, cardiovascular disease to plastics
In a mouse study, a team led by a biomedical scientist found a phthalate -- a chemical used to make plastics more durable -- led to increased plasma cholesterol levels......»»
Coffee time: Caffeine improves reaction to moving targets
In the first study of its kind to explore caffeine's effects on dynamic visual skills, researchers concluded that caffeine increases alertness and detection accuracy for moving targets. Caffeine also improved participants' reaction times......»»
MRI reveals altered brain structure in fetuses exposed to alcohol
In the first MRI-based study to investigate pre-natal alcohol exposure, researchers found significant changes in the brain structure of fetuses exposed to alcohol compared to healthy controls......»»
