A University of Michigan-led study based on a review of genetic and health information from more than 276,000 people finds strong support for a decades-old evolutionary theory that sought to explain aging and senescence.   In 1957, evolutionary biologist George Williams proposed that genetic mutations that contribute to aging could be favored by natural selection if they are advantageous early in life in promoting earlier reproduction or the production of more offspring. Williams was an assistant professor at Michigan State University at ...

December 8, 2023 (Toronto) – CAMH-led pre-clinical studies using a small molecule drug have shown promise as a potential new treatment for multiple sclerosis (MS). The results have been published today in the journal Science Advances.

SAN FRANCISCO—December 8, 2023—It only takes holding your breath for slightly too long to understand that too little oxygen is bad for you. But can you also have too much? Indeed, breathing air with a higher oxygen level than your body needs can cause health problems or even death.   But with scant research on the topic, scientists have known little about how the body senses too much oxygen. Now, a new study from Gladstone Institutes has greatly expanded the scientific body of knowledge about the mechanisms at play, and why it matters for health. Their findings, reported in the journal Science Advances, explain how breathing air with different levels of ...

The advent of this minimally invasive approach, known as blood-based liquid biopsy, ...

The most durable, heat-resistant materials ever made could be hiding in plain sight. The U.S. Department of Defense wants to know if minerals and rocks found on Earth and in space hold the secrets of next-generation high-temperature materials. To find out, the DOD awarded $6.25 million through its Multidisciplinary University Research Initiative, or MURI, to a team from the University of Virginia and Arizona State University. The group is led by UVA’s Elizabeth J. Opila, the Rolls-Royce Commonwealth Professor and chair of the Department of Materials Science and Engineering. The ...

Magnesium oxide is a promising material for capturing carbon dioxide directly from the atmosphere and injecting it deep underground to limit the effects of climate change. But making the method economical will require discovering the speed at which carbon dioxide is absorbed and how environmental conditions affect the chemical reactions involved. Scientists at the Department of Energy’s Oak Ridge National Laboratory analyzed a set of magnesium oxide crystal samples exposed to the atmosphere for decades, and another for days to months, to gauge the reaction rates. They found that carbon ...

A study looking at 15 years of HIV transmission and suppression in Uganda reveals how closing gender gaps in treatment could slash infection rates. Providing more heterosexual men with easy access to HIV treatment and care could help to suppress the virus and rapidly cut transmission to their female partners, shows a new study published in Nature Microbiology. The research, led by scientists from Imperial College London and the Rakai Health Sciences Program in Uganda, analysed 15 years of data from 2003-2018, during which the US President’s Emergency Plan For AIDS ...

When Senior Scientist Jonathan Grimm came to Janelia 13 years ago, he didn’t know much about fluorescence or fluorescent dyes. But as an organic chemist who had been working in drug discovery at Merck, he certainly knew a thing or two about medicinal chemistry. On a whim, Grimm and Janelia Senior Group Leader Luke Lavis decided to try using a mainstay medicinal chemistry reaction Grimm had picked up in the pharmaceutical industry to improve centuries-old dye chemistry. They thought this approach could allow access to completely new, previously inaccessible rhodamines – molecules Lavis had been working to make brighter and longer-lasting so they could be ...

Nuclear fusion, the process that powers the sun, is the ultimate source of energy for all life on Earth. On the sun, deuterium and tritium nuclei combine to produce an alpha particle (the nucleus of a helium atom) and a neutron. The dream is to do the same down here, on Earth, in a controlled manner. It’s for good reason that harnessing fusion energy is one of the greatest scientific and technological challenges of the 21st century. Fusion requires the fuel to be heated to more than 100 million degrees (10 times hotter than the core of the sun). Practical fusion energy also requires that the burning fuel is kept at these hot temperatures long enough so that energy ...

More than 1.2 million people have died in the United States during the COVID-19 pandemic to date, more documented deaths than any other nation on Earth. While many have attributed the high death toll on widespread personal hesitancy to wear masks, avoid crowded places or receive vaccines once they were developed, there were several “system hesitancies” that contributed to the tragic outcomes that need addressing, according to an analysis published Dec. 6, 2023, in Health Affairs Forefront. The analysis ...

LA JOLLA, CA—In August, researchers detected a new SARS-CoV-2 "variant of concern" in patients in Israel and Denmark. Since then, this variant, dubbed BA.2.86 or "Pirola," has made its way around the globe. The Pirola variant has raised alarms because it is highly mutated. In fact, Pirola is as mutated as the Omicron variant was, compared with the early SARS-CoV-2 variant included in the original vaccinations.  As Pirola spreads, researchers at La Jolla Institute for Immunology (LJI) are investigating whether COVID-19 vaccines (or previous ...

MIT engineers have developed a robotic replica of the heart’s right ventricle, which mimics the beating and blood-pumping action of live hearts.  The robo-ventricle combines real heart tissue with synthetic, balloon-like artificial muscles that enable scientists to control the ventricle’s contractions while observing how its natural valves and other intricate structures function.  The artificial ventricle can be tuned to mimic healthy and diseased states. The team manipulated the model to simulate conditions of right ventricular dysfunction, ...

A recent study from researchers in Canada and Germany has revealed that an unlikely event, occurring over 12 million years ago played an important role in shaping one of Canada’s most damaging invasive species. Zebra and quagga mussels, belonging to the Dreissenid family, are widespread freshwater invasive species throughout North America that present a significant danger to native ecosystems by competing for resources. Using a fibrous anchor called a byssus, Dreissenid mussels contribute to biofouling on surfaces and obstruct intake structures in power stations and water treatment plants. “This new study, which looks into the way these mussels stick to surfaces, may help improve ...

SAN ANTONIO – Patients with low-risk ductal carcinoma in situ (DCIS) who skipped adjuvant radiotherapy after breast-conserving surgery had comparable five-year outcomes to those with high-risk DCIS who received adjuvant radiotherapy, according to results from the E4112 clinical trial presented at the San Antonio Breast Cancer Symposium, held December 5-9, 2023. “Nearly all women with DCIS—a noninvasive form of breast cancer—will have their cancer successfully removed, but some women will have a high risk of the disease returning or progressing to invasive breast cancer,” said Seema A. Khan, MD, a professor of surgery and the Bluhm Family ...

Women 50 or older who de-escalated to less-frequent mammography three years after curative surgery for early-stage breast cancer had similar outcomes to women who received annual mammography, according to results from the Mammo-50 trial presented at the San Antonio Breast Cancer Symposium, held December 5-9, 2023. Both U.S. and U.K. guidelines recommend annual breast cancer screening following surgery to remove early-stage breast cancer; in the U.S., annual mammography is recommended indefinitely, and in the U.K., it is recommended for five years, followed by screening every three years for patients 50 years and older. However, the optimal screening schedule has yet to ...
