UW Medicine genome experts made significant scientific contributions to a National Institutes of Health Human Genome Research Institute reference collection that better represents the genetic diversity of the world’s populations. Called the Human Pangenome Reference Consortium, the multi-institutional effort expands and updates earlier work that started as the Human Genome Project. That original project, with drafts reported in 2001 and 2003, was based on a more limited sampling of human DNA. The goal then was to create an entire sequence of a human genome to use as a reference. ...

For more than 20 years, scientists have relied on the human reference genome, a consensus genetic sequence, as a standard against which to compare other genetic data. Used in countless studies, the reference genome has made it possible to identify genes implicated in specific diseases and trace the evolution of human traits, among other things. But it has always been a flawed tool. One of its biggest problems is that about 70 percent of its data came from a single man of predominantly African-European background whose DNA was sequenced during ...

For more than a decade, astronomers have been trying to get a closer look at GJ 1214b, an exoplanet 40 light-years away from Earth. Their biggest obstacle is a thick layer of haze that blankets the planet, shielding it from the probing eyes of space telescopes and stymying efforts to study its atmosphere. NASA’s new James Webb Space Telescope (JWST) solved that issue. The telescope’s infrared technology allows it to see planetary objects and features that were previously obscured ...

A ‘Matter Arising’ paper published in Nature today refutes the findings of a paper by Sala et al on the amount of CO2 released from the seabed by bottom trawling. The paper made significant headlines around the world on release in 2021, as it equated the carbon released by bottom trawling to be of a similar magnitude to the CO2 created by the global airline industry. In their paper quantifying the carbon benefits of ending bottom trawling, Prof Jan Hiddink of Bangor University’s world-renowned School of Ocean Science and others, explain that the methodology ...

Implantable bioelectrodes are electronic devices that can monitor or stimulate biological activity by transmitting signals to and from living biological systems.

AMES, IA — Like many first responders, law-enforcement investigators and detectives often struggle with sleep. Late-night shifts, stress, and the 24-hour nature of crime can throw off biological clocks and cut sleep cycles short. Along with the negative health implications, new research indicates officers who are fatigued have a harder time collecting information that could bring justice to victims. Zlatan Križan, a sleep scientist and psychology professor at Iowa State University, led the study. He ...

Washington, DC – Fungi produce metabolites that humans have used to improve health. For example, they secrete penicillin, which is then purified and used as an antibiotic for humans, leading to the development of many other antibiotics. However, the ecology of fungal metabolites in microbial communities is not well understood. In a new study, researchers use cheese rinds to demonstrate that fungal antibiotics can influence how microbiomes develop. The study is published in mBio, an open-access journal of the American Society for Microbiology.  “My lab is interested in how ...

An increasing number of Floridians agree that human actions are causing climate change, including a record number of Florida Republicans, according to a new survey from Florida Atlantic University. This finding reinforces the trend observed in the prior seven Florida Climate Resilience Surveys, conducted by FAU’s Center for Environmental Studies within the Charles E. Schmidt College of Science.   Three main messages emerge from this latest poll. First, climate change is no longer an effective partisan wedge issue. Virtually all respondents (90 percent) ...

An international study led by MELIS-UPF researchers from the Infection Biology and Molecular Virology laboratories has identified and characterized Schlafen 12 (SLFN 12) as a novel HIV restriction factor. SLFN 12 shuts down viral protein production and helps virus-infected cells to escape from anti-HIV therapy and immune responses. These findings pave the way for improving therapeutic strategies that aim to cure HIV infections. Human Immunodeficiency Virus (HIV) infections, if left untreated, lead to the gradual destruction of the immune system, AIDS, in its final stages. Worldwide, some 650,000 ...

A new drug delivery system delivers an antioxidant directly to mitochondria in the liver, mitigating the effects of oxidative stress. Mitochondria are microscopic organelles found within cells, and are well-known as the “powerhouse of the cell.” They are by far the largest producer of the molecule adenosine triphosphate (ATP), which provides energy to many processes in living cells. The process by which mitochondria synthesize ATP generates a large amount of reactive oxygen species (ROS), chemical groups that are highly reactive. In a healthy cell, the ROS are controlled by the mitochondria; however, when this balance is lost, the excess ROS damages the mitochondria ...

With each breath, humans exhale more than 1,000 distinct molecules, producing a unique chemical fingerprint or “breathprint” rich with clues about what’s going on inside the body. For decades, scientists have sought to harness that information, turning to dogs, rats and even bees to literally sniff out cancer, diabetes, tuberculosis and more. Scientists from CU Boulder and the National Institute of Standards and Technology (NIST) have made an important leap forward in the quest to diagnose disease using exhaled breath, reporting that a new laser-based breathalyzer powered by artificial intelligence (AI) can detect COVID-19 in real-time with ...

May 10 2023, Utrecht (The Netherlands) - When corona patients themselves measure the oxygen level in their blood at home, this is well applicable through the general practice. This was shown in a study conducted by UMC Utrecht during the pandemic. The study showed that patients could easily perform the oxygen measurement themselves at home, they felt safe doing so and the number of GP or hospital visits did not increase. The researchers believe that - by enabling care close to home - patients experience more control and that it contributes to relieving caregivers and keeping ...

A new paper in the European Journal of Endocrinology, published by Oxford University Press, indicates that overweight boys tend to have lower testicular volume, putting them at risk for infertility in adulthood. Infertility weighs on both the psychological health and the economic and social lives of people of childbearing age. Infertility affected 48 million couples in 2010. Although observers often overlook male infertility, researchers believe it is a factor contributing to couple infertility in about half of all cases. Yet ...
