Complications during pregnancy (or adverse pregnancy outcomes), like gestational diabetes and newly developed high blood pressure, act as nature’s stress test and may uncover an individual’s risk for heart disease later in life, according to new research published in the JACC, the flagship journal of the American College of Cardiology. The study also highlights how weight management before pregnancy may not only improve maternal health but also reduce future cardiovascular disease risk. The observational study, which ...

Cardiovascular disease is by far the most common cause of death worldwide, and myocardial infarction is the most common acute event. For those who survive a myocardial infarction, the risk of a new heart attack is greatest in the first year after the initial event because the blood vessels are more sensitive, making it easier for blood clots to develop. Reducing the “bad” cholesterol in the blood stabilises changes in the vessels, decreasing the risk for new events. The current established routine treatment is to treat with high-potency statins, immediately after the infarction. However, the majority ...

New tool for cutting DNA: promising prospects for biotechnology  An INRS team discovers a new family of enzymes capable of inducing targeted cuts in single-stranded DNA   A few years ago, the advent of technology known as CRISPR was a major breakthrough in the scientific world. Developed from a derivative of the immune system of bacteria, CRISPR enables double strands of nucleotides in deoxyribonucleic acid (DNA) to be cut.  This makes it possible to specifically modify a targeted gene in plant, animal and human cells. Ultimately, CRISPR became a preferred method in the search for treatments for acquired or hereditary diseases.   Recently, ...

Victoria, BC— For the first time, footprints of armoured dinosaurs with tail clubs have been identified, following discoveries made in the Canadian Rockies. The 100-million-year-old fossilized footprints were found at sites at both Tumbler Ridge, BC, and northwestern Alberta. There are two main groups of ankylosaurs. Nodosaurid ankylosaurs have a flexible tail and four toes, while ankylosaurid ankylosaurs have a sledgehammer-like tail club, and only three toes on their feet. Unlike the well-known ankylosaur footprints called Tetrapodosaurus ...

COLUMBUS, Ohio – Insomnia and hazardous drinking are so closely intertwined that estimates suggest at least one-third, and as many as 91%, of people who have a hard time with sleep also misuse alcohol. A new study suggests that perceived stress and depression factor into the relationship between the two conditions – perhaps not a surprise. But because the relationship between insomnia and heavy drinking goes in both directions, the influence of stress or depression depends on which condition came first, the analysis found. “We were most interested in how insomnia leads to drinking, and we found that seems to occur primarily through ...

Years of research in the field of genetics have offered interesting insights spanning the origins and development of heredity and traits, offering valuable information on its influence on every aspect of life, right from eye color to susceptibility to certain diseases. But how do our genes influence the way we act, react to threats, and interact with others? Despite the recent advances in genetics, understanding the genetic foundations of behavior remains one of biology’s most fascinating challenges. Scientists have long turned to simpler organisms to help answer these questions, with the humble fruit fly emerging as an ideal candidate. These tiny insects share ...

An international team of researchers may have answered one of space science’s long-running questions – and it could change our understanding of how life began.   Carbon-rich asteroids are abundant in space yet make up less than 5 per cent of meteorites found on Earth.   An international team of scientists from Curtin University’s School of Earth and Planetary Sciences, the International Centre for Radio Astronomy (ICRAR), the Paris Observatory and more scoured the globe to find an answer.   Published today in Nature Astronomy, researchers analysed close to 8500 meteoroids and meteorite impacts, using data from ...

Statement Highlights: While the strongest evidence exists that getting sufficient sleep (duration of sleep) is important for overall health , other components of sleep health, such as consistent bedtime, uninterrupted sleep, daytime functioning and self-reported sleep satisfaction, also contribute to cardiometabolic health and related risk factors, including heart disease, stroke, high blood pressure, high cholesterol, inflammation, glucose intolerance, obesity and obstructive sleep apnea. Differences in sleep health may contribute to increased risk factors and worse health outcomes, particularly for people in under-resourced communities and individuals ...

Researchers from the University of Birmingham have uncovered answers that provide the detail to explain two specific DNA repair processes that have long been in question. The publication of two papers demonstrates how work led by laboratories from the Department of Cancer and Genomic Sciences, and School of Biosciences at the University of Birmingham has made strides in understanding how the repair process is correctly orchestrated.

When DNA is damaged, internal signals activate within the cell to pinpoint the damage and recruit specialised proteins—DNA ...

Microplastics and the much smaller nanoplastics enter the human body in various ways, for example through food or the air we breathe. A large proportion is excreted, but a certain amount remains in organs, blood and other body fluids. In the FFG bridge project Nano-VISION, which was launched two years ago together with the start-up BRAVE Analytics, a team led by Harald Fitzek from the Institute of Electron Microscopy and Nanoanalysis at Graz University of Technology (TU Graz) and an ophthalmologist from Graz addressed the question of whether nanoplastics also play a role in ophthalmology. The project partners have now been able to develop a method for detecting and quantifying nanoplastics ...

Rates of colorectal cancer (CRC) diagnoses dropped during and shortly after Hurricanes Irma and Maria and the COVID-19 pandemic in Puerto Rico, according to a recent analysis. However, late-stage diagnoses eventually exceeded expectations, suggesting that limited access to cancer screening services due to these disasters likely hindered timely CRC diagnoses. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society. During disasters, medical services may be delayed or inaccessible due to damaged infrastructure, overburdened health ...

Sleep is a necessary part of people’s daily routine, but modern lifestyles and technology have ushered in an era of decreased rest time and subsequent fatigue. Further, the bedroom environment, such as light, sound, and temperature, is important for a good night's sleep, though this is often neglected in residential architecture. In search of a conclusive remedy, common sleep studies use artificial light that is easy to control. Osaka Metropolitan University researchers, however, believe natural light could be more effective for re-creating actual living environments. To test this, Graduate School of Human Life and Ecology student Xiaorui Wang and Professor ...

Farmers in dozens of countries have embraced crops genetically engineered to produce proteins from Bacillus thuringiensis (Bt) bacteria that kill some key pests yet are safe for people and wildlife. Although this biotech approach reduces reliance on insecticide sprays thereby providing economic and environmental benefits, resistance to Bt crops has evolved in at least 11 species of pests. Thus, effective ways to combat such pest resistance are urgently needed. A new study published in the Proceedings of the National Academy of Sciences identifies a natural strategy for thwarting pest resistance to Bt proteins. The researchers at the University of Arizona and ...
