Common hypertension medications may reduce colorectal cancer risk

People who take angiotensin converting enzyme inhibitors (ACE-i) or angiotensin II receptor blockers (ARBs) for conditions such as high blood pressure were less likely to be diagnosed with colorectal cancer after having a normal colonoscopy.This is the first study to show potential benefits on colorectal cancer development from these commonly prescribed hypertension medications, based on a study...

Compounds halt SARS-CoV-2 replication by targeting key viral enzyme

University of South Florida Health (USF Health) Morsani College of Medicine scientists recently worked with colleagues at the University of Arizona College of Pharmacy to identify several existing compounds that block replication of the COVID-19 virus (SARS-CoV-2) within human cells grown in the laboratory. The inhibitors all demonstrated potent chemical and structural interactions with a viral...

Consumers prefer round numbers even when the specific number is better news

Consider this scenario: A vaccine for the novel coronavirus has been developed that is 91.27% effective. If public health officials present this information using the specific number, people are likely to think the vaccine is actually less effective than if it is presented as being 90% effective. This concept is a real-life application of recent findings from Gaurav Jain, an assistant professor of...

Coronary calcium scoring: Personalized preventive care for those most at risk

An imaging test called coronary calcium scoring can help doctors to make the right recommendation about the use of statin therapy. The test is a 10-minute CT (computed tomography) scan looking for calcium deposits in the arteries supplying blood to the heart. Calcium deposits indicate the presence of coronary plaque, also known as atherosclerosis.

COVID-19 shines spotlight on gender inequity in academia

In a new article, a team of 17 faculty members from across the nation, including nine from Texas Tech, examines how the pandemic amplifies gender inequity and proposes novel solutions. The article was published recently in the Proceedings of the National Academy of Sciences of the United States of America.

Cranfield academics call for 'Five Capitals' approach to global resilience

Writing in the leading academic journal, Nature, Cranfield academics are calling for global resilience to be shaped around the 'Five Capitals' - natural, human, social, built and financial. The academics believe that too often silos exist within Government and within organisations and businesses that mean risks are not anticipated quickly enough or prepared for well enough.

Desert algae shed light on desiccation tolerance in green plants

Deserts of the US Southwest are extreme habitats for most plants, but, remarkably, microscopic green algae live there that are extraordinarily tolerant of dehydration. After completely drying out, the algae can become active and start photosynthesizing again within seconds of receiving a drop of water. Elena Peredo and Zoe Cardon of the Marine Biological Laboratory provide a genetic explanation...

Electrically focus-tuneable ultrathin lens for high-resolution square subpixels

In accordance to rising demand of high-resolution, ultrathin lens device for display panels, the scientists from Korea, UK, and USA have invented an electrically focus-tunable, graphene-based ultrathin subpixel square lens device that demonstrates excellent focusing performance. Such subpixel design is uniquely developed to control the optical path of subpixels of display in visible wavelength,...

Epigenetics: What the embryo can teach us about cell reprogramming

Cell reprogramming provides an outstanding opportunity for the artificial generation of stem cells for regenerative medicine approaches in the clinic. As current cell reprogramming methods are low in efficiency, researchers around the globe aim to learn lessons from the early embryo which might lead them to a more efficient and faster generation of high-quality, fully reprogrammed stem cells.

Fathers are more likely to be referred for nutrition or exercise counseling

Fatherhood status has been linked to medical providers' weight-related practices or counseling referrals. A new study in the Journal of Nutrition Education and Behavior, published by Elsevier, found that overweight and obese men who are fathers were more likely than men without children to be referred for nutrition or exercise counseling.

First direct evidence of ocean mixing across the gulf stream

Study in the Proceedings of the National Academy of Sciences provides first direct evidence for Gulf Stream blender effect, identifying a new mechanism of mixing water across the swift-moving current. The results have important implications for weather, climate and fisheries because ocean mixing plays a critical role in these processes. The Gulf Stream is one of the largest drivers of climate and...

Follow-up appointments for children hospitalized for bronchiolitis may not be needed

A new study at Intermountain Primary Children's Hospital in Salt Lake City has found that follow-up appointments for hospitalized children treated for childhood bronchitis are often not necessary, and that switching from mandatory to 'as-needed' follow-up care can save families from unnecessary medical care and expense - and may help guide treatment during the COVID-19 pandemic.

Group genomics drive aggression in honey bees

Researchers often study the genomes of individual organisms to try to tease out the relationship between genes and behavior. A new study of Africanized honey bees reveals, however, that the genetic inheritance of individual bees has little influence on their propensity for aggression. Instead, the genomic traits of the hive as a whole are strongly associated with how fiercely its soldiers attack.

Gut bacteria improve type 2 diabetes risk prediction

The composition and function of bacteria in the human intestine -- the so-called gut microbiome -- changes as the day progresses. This was established by researchers based in Freising at ZIEL - Institute for Food & Health of the Technical University of Munich (TUM) with one of the largest studies related to microbiomes and diabetes comprising more than 4000 participants. These daily variations in...

Harmful microbes found on sewer pipe walls

Can antibiotic-resistant bacteria escape from sewers into waterways and cause a disease outbreak? A new Rutgers study, published in the journal Environmental Science: Water Research & Technology, examined the microbe-laden "biofilms" that cling to sewer walls, and even built a simulated sewer to study the germs that survive within.
