Genetic vulnerability to menthol cigarette use Posted: 15 Feb 2019 01:20 PM PST A genetic variant found only in people of African descent significantly increases a smoker's preference for cigarettes containing menthol, a flavor additive. The variant of the MRGPRX4 gene is five to eight times more frequent among smokers who use menthol cigarettes than other smokers. The multi-ethnic study is the first to look across all genes to identify genetic vulnerability to menthol cigarettes. |
Drug to rejuvenate muscle cells Posted: 15 Feb 2019 01:20 PM PST Researchers have developed a promising drug that has proven to significantly increase muscle size, strength and metabolic state in aged mice, according to a new study. |
Open-science model for drug discovery expands to neurodegenerative diseases Posted: 15 Feb 2019 01:20 PM PST Parkinson's disease and Amyotrophic Lateral Sclerosis are the newest frontiers for open science drug discovery, a global movement led by academic scientists that puts knowledge sharing and medication affordability ahead of patents and profits. |
Patients' own cells could be the key to treating Crohn's disease Posted: 15 Feb 2019 08:03 AM PST A new technique using patients' own modified cells to treat Crohn's disease has been proven to be effective in experiments using human cells, with a clinical trial of the treatment expected to start in the next six months. |
Bioengineers create ultrasmall, light-activated electrode for neural stimulation Posted: 15 Feb 2019 08:02 AM PST Scientists have detailed a less invasive method of neural stimulation that would use an untethered ultrasmall electrode activated by light, a technique that may mitigate damage done by current methods. |
Exercise might improve health by increasing gut bacterial diversity Posted: 15 Feb 2019 05:24 AM PST Research has suggested that the efficiency with which we transport oxygen to our tissues (cardiorespiratory fitness) is a far greater predictor of gut microbiota diversity than either body fat percentage or general physical activity. |
'Cellular barcoding' reveals how breast cancer spreads Posted: 15 Feb 2019 05:23 AM PST A cutting-edge technique called cellular barcoding has been used to tag, track and pinpoint cells responsible for the spread of breast cancer from the main tumour into the blood and other organs. |
Posted: 15 Feb 2019 05:23 AM PST A new study may resolve a decades-old debate in immunology: researchers report that distinct progenitor cells are not required for the development of B1 cells. Instead, the team's experiments show that a B1-typical B-cell receptor can reprogram B2 cells into B1 cells, suggesting that B1 cells emerge as a consequence of their special B-cell receptors. |
New live-imaging technique reveals cellular repair crew plugging leaky biological barrier Posted: 15 Feb 2019 05:23 AM PST Suppose you live in a brick house and notice cracks in the mortar that let in cold air, rain and insect pests. You might call a brick mason to repair those leaks and to restore the barrier that keeps the great outdoors from getting inside. |
Interval training may shed more pounds than continuous moderate intensity workout Posted: 14 Feb 2019 04:19 PM PST Interval training may shed more pounds than a continuous moderate intensity workout, suggests a pooled analysis of the available evidence. |
Posted: 14 Feb 2019 04:19 PM PST New research shows that an immersive virtual reality environment treats 45 percent of children with autism, freeing them from their fears and phobias -- and that the treatment lasts. |
Brain connections that disadvantage night owls revealed Posted: 14 Feb 2019 04:19 PM PST 'Night owls' -- those who go to bed and get up later -- have fundamental differences in their brain function compared to 'morning larks,' which mean they could be disadvantaged by the constraints of a normal working day. |
Teens living in US states allowing medical marijuana smoke less cannabis Posted: 14 Feb 2019 04:19 PM PST According to a large-scale study of American high school students, legalizing medicinal marijuana has actually led to a drop in cannabis use among teenagers. The study used the results of an anonymous survey given to more than 800,000 high school students across 45 states to calculate the number of teens who smoke cannabis. |
It doesn't take much for soldiers to feel cared for Posted: 14 Feb 2019 02:42 PM PST Caring texts sent to active-duty military had important findings in reducing suicide. |
Study on measles transmission in China have implications for controlling the epidemic worldwide Posted: 14 Feb 2019 02:42 PM PST A new study on the measles epidemic in China has far-reaching implications for eliminating the infection globally. Using a new model-inference system, the researchers were able to estimate population susceptibility and demographical characteristics in three key locations in China, in a period that spans the pre-vaccine and modern mass-vaccination eras. |
Giving keener 'electric eyesight' to autonomous vehicles Posted: 14 Feb 2019 12:32 PM PST Autonomous vehicles relying on light-based image sensors often struggle to see through blinding conditions, such as fog. But researchers have developed a sub-terahertz-radiation receiving system that could help steer driverless cars when traditional methods fail. |
Study examines how compound damaged DNA to understand its connection to cancer Posted: 14 Feb 2019 12:31 PM PST In an effort to understand how colibactin, a compound produced by certain strains of E. coli, may be connected to the development of colorectal cancer, researchers are exploring how the compound damages DNA to produce DNA adducts. |
New tool for documenting injuries may provide better evidence for elder abuse cases Posted: 14 Feb 2019 12:30 PM PST Scientists have developed the first standardized framework for clinicians to document physical findings on older patients for better evidence in abuse cases. |
A weakness in a rare cancer that could be exploited with drugs Posted: 14 Feb 2019 12:30 PM PST Researchers have identified a rare type of cancer cell that cannot make cholesterol, a key nutrient. By targeting this deficiency, scientists may be able to develop new strategies for treating the disease. |
Effective self-control strategies involve much more than willpower Posted: 14 Feb 2019 12:30 PM PST It's mid-February, around the time that most people waver in their commitment to the resolutions they've made for the new year. Many of these resolutions require us to forego a behavior we want to engage in for the one we think we should engage in. In a new report, leading researchers in behavioral science propose a new framework that outlines different types of self-control strategies and emphasizes that self-control entails more than sheer willpower to be effective. |
Most triggers for irregular heartbeat can be easily modified Posted: 14 Feb 2019 09:04 AM PST A personal survey of patients with atrial fibrillatio, one of the most important causes of irregular heartbeats, has found that the majority of triggers for the condition are easily modifiable lifestyle choices, including alcohol, caffeine, exercise and lack of sleep. |
