In a study published in Nature Astronomy today, a team of researchers from the University of Naples “Federico II”, the University of Wroclaw, and the University of Bergen examined a quantum-gravity model of particle propagation in which the speed of ultrarelativistic particles decreases with rising energy. This effect is expected to be extremely small, proportional to the ratio between particle energy and the Planck scale, but when observing very distant astrophysical sources, it can accumulate to observable levels. The ...

An overactive inflammatory response could be at the root of many long COVID cases, according to a new study from the Allen Institute and Fred Hutchinson Cancer Center. Looking at proteins circulating in the blood, the scientists found a set of molecules associated with inflammation that were present only in a subset of patients with long COVID and were not seen in those who recovered from their disease. The researchers published an article describing their findings in the journal Nature Communications today. Out of 55 patients with long ...

Two major ridesharing companies have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. To understand additional impacts of this transition, researchers reporting in ACS’ Environmental Science & Technology conducted life-cycle comparisons of battery-powered electric vehicle fleets to a gas-powered one, using real-world rideshare data. They found up to a 45% reduction in greenhouse gas emissions from full electrification; however, traffic problems and air pollution could increase. Ridesharing apps are an increasingly popular way to travel around urban areas, ...

Taking biofabrication to the next level: innovations in volumetric bioprinting UMC Utrecht researchers propose solutions for bioprinting living tissue Bioprinting is the printing of living cells and tissues. It's a promising technique that hopefully, one day, can solve the organ donor shortage by growing organs from patients' own cells. However, printing living tissues and cells is extremely complicated, and many hurdles need to be overcome to be able to get there. In this article, three recent innovations ...

Cellular stress, or oxidative stress, occurs when there is a buildup of reactive oxygen species (ROS), which interferes with cellular mechanisms and can even cause damage to proteins, lipids, and DNA. Owing to their destructive nature, all cells have robust mechanisms in place to remove ROS and reduce oxidative stress. One such mechanism is the nuclear factor erythroid 2-related factor 2 (NRF2)-mediated stress response, where NRF2 is a master transcription factor that aids in reducing oxidative stress.   Much is known about the redox-dependent activation of NRF2 and its subsequent role in stress response. In this pathway, ...

Statement Highlights: Around the world, most people are regularly exposed to low or moderate levels of lead, cadmium and arsenic in the environment, increasing risk of coronary artery disease, stroke and peripheral artery disease, according to a new American Heart Association statement. These metals, considered contaminant metals, have no function in the human body. They are found in groundwater, water pipes, paint, tobacco products, fertilizer, plastic, electronics, gasoline, batteries, some foods and other commonly used items. Lead, ...

Study’s findings point to the importance of considering other risk factors beyond breast density. Dense breast tissue, which contains a higher proportion of fibrous tissue than fat, is a risk factor for breast cancer and also makes it more difficult to identify cancer on a mammogram. Many states have enacted laws that require women with dense breasts to be notified after a mammogram, so that they can choose to undergo supplemental ultrasound screening to improve cancer detection. A recent study published ...

The number of species of the green alga sea lettuce in the Baltic Sea region and Skagerak and  is much larger than what was previously known. Researchers at the University of Gothenburg have surveyed 10,000 kilometres of coast and found twenty species of sea lettuce. Green macroalgae of the genus Ulva, also known as sea lettuce, are almost ubiquitous in the wider Baltic Sea region and and can be found from the Atlantic waters all the way up to the Bay of Bothnia in the Baltic Sea. Sea lettuce reproduce easily and grow ...

Pandemic restrictions corresponded with a significant drop in diagnoses of breast, colorectal and prostate cancers as well as melanoma, according to a new Alberta study published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.221512. "The sweeping and unprecedented measures enacted at the beginning of the COVID-19 pandemic in Alberta had an inevitable impact on cancer care," writes Dr. Darren Brenner, an epidemiologist in Calgary, Alberta, and associate professor at the University of Calgary's Cumming School of Medicine, with coauthors. "Even though treatment and urgent surgeries for cancers were prioritized ...

By putting a price on the cost of carbon, the Government of Canada aims to curtail greenhouse gas (GHG) emissions, but it comes with an increased risk for financial lenders and borrowers with high carbon emissions.  In a first-of-its-kind study, University of Waterloo researchers analyzed the effects of Canada’s carbon price regime on the economy. The results indicate that as carbon costs rise, high-emitting carbon industries such as mining and energy are at the greatest risk of default, with total assets of $256 billion at risk of being lost and almost a quarter ...

Abu Dhabi, UAE (June 12): A team of researchers at NYU Abu Dhabi, led by Associate Professor of Biology Youssef Idaghdour and working in collaboration with clinicians at several Abu Dhabi hospitals, investigated the association between microRNAs, a class of small RNA molecules that regulate genes, and COVID-19 severity among 259 unvaccinated COVID-19 patients living in Abu Dhabi. The team identified microRNAs that are associated with a weakened immune response and admission to ICU. During this process, ...

UNIVERSITY PARK, Pa. — A human or animal’s microbiome — the collection of often beneficial microorganisms, including as bacteria and fungi, that live on or within a host organism — can play an important role in the host’s overall immune response, but it is unclear how vaccines against harmful pathogens impact the microbiome. A new study led by researchers at Penn State found that a new vaccine against the deadly chytrid fungus in frogs can shift the composition of the microbiome, making frogs more resilient to future exposure to the ...

Modern-day society relies intrinsically on automated systems and artificial intelligence. It is embedded into our daily routines and shows no signs of slowing, in fact use of robotic and automated assistance is ever-increasing.  Such pervasive use of AI presents technologists and developers with two ethical dilemmas – how do we build robots that behave in line with our values and how to we stop them going rogue?  One author suggests that one option which is not explored enough is to code more humanity into robots, gifting robots with traits such as empathy and compassion. Is ...

Glasgow, UK: Xeroderma pigmentosum (XP) is a rare and devastating genetic disorder characterised by an inability to repair skin damage caused by ultraviolet (UV) light.  As a result, patients with XP develop skin cancers, usually in childhood. Once diagnosed, they can be protected by avoiding sunlight (hence sometimes being called ‘children of the night’), wearing special clothing and sunglasses, and using sunscreen. But some will also develop neurodegenerative conditions such as hearing loss, loss of intellectual function, poor co-ordination and seizures. Finding out why this is, and which ...

Glasgow, UK: Rates of colorectal cancer are high despite widespread adoption of screening programmes in many high-income European countries. Such programmes tend to use a one-size-fits-all approach where most people are screened starting from the same age, and no individual factors are considered in organised population screening. Now, based on one of the largest genomics studies on the topic to date, researchers from Finland have outlined how common genetic factors could be used to identify individuals at high risk of developing the disease and hence improve current colorectal screening strategies. Max Tamlander, MD at the Institute ...

Glasgow, UK: Genetic counselling is essential when dealing with individuals who are affected by, or at risk of, inherited disease. Although it is known to be useful in helping patients cope with test results and deal with uncertainty, there have been very few randomised controlled trials (RCTs) of its effectiveness. Dr Andrada Ciuca, a post-doctoral researcher at Babes-Bolyai University, Cluj-Napoca, Romania, will tell the annual conference today (Sunday 11 June) that the results of the first RCT of genetic counselling in familial colorectal cancer (fCRC) show that it provided significant ...

Glasgow, UK: Being to identify people at high risk of chronic disease means that they can be targeted with prevention measures before they become sick. Polygenic risk scores, where genomic information alone is used to assess the risk of developing diseases, have been receiving a lot of attention recently, but research to be presented at the annual conference of the European Society of Human Genetics today (Saturday 10 June) suggests that combining blood biomarkers with genomic information gives more accurate, cost-effective results. Dr Jeffrey Barrett, Chief Scientific Officer, Nightingale Health, Helsinki, ...
