What if time is not as fixed as we thought?

Physicists uncover evidence of two arrows of time emerging from the quantum realm Date: February 13, 2025 Source: University of Surrey Summary: What if time is not as fixed as we thought? Imagine that instead of flowing in one direction -- from past to future -- time could flow forward or backward due to processes taking place at the quantum level. This is the thought-provoking discovery made by researchers, as a new study reveals that opposing arrows of time can theoretically emerge from certain quantum systems. Imagine that instead of flowing in one direction -- from past to future -- time could flow forward or backwards due to processes taking place at the quantum level. This is the thought-provoking discovery made by researchers at the University of Surrey, as a new study reveals that opposing arrows of time can theoretically emerge from certain quantum systems. For centuries, scientists have puzzled over the arrow of time – the idea that time flows irreversibly from past to future...

New treatment may offer quick cure for common cause of high blood pressure Date: February 10, 2025 Source: Queen Mary University of London Summary: A revolutionary new treatment called Targeted Thermal Therapy (Tripel T) offers a safer, faster alternative to surgery for patients with high blood pressure caused by Primary Aldosteronism, a hormonal disorder. Development of Triple T for Hypertension Treatment: Innovation : Doctors at Queen Mary University of London, Barts Health NHS Trust, and UCL developed Triple T (Targeted Thermal Therapy) for treating primary aldosteronism, a common yet overlooked cause of high blood pressure. Minimally invasive, faster, and safer than adrenal gland surgery. Breakthrough Study : Published in The Lancet . Potential to aid millions worldwide after further testing. High Blood Pressure & Primary Aldosteronism: Prevalence : Affects 1 in 3 adults; primary aldosteronism accounts for 1 in 20 cases. Less than 1% diagnosed due to challenges...

Short bursts of physical activity cut women’s risk of heart attack

Just a few minutes of vigorous movement per day offers cardiovascular benefits Photo by Vidar Nordli-Mathisen on Unsplash A dash of vigorous activity a day could keep the heart troubles away. Women who included short bursts of intense physical activity in their daily routines saw their  risk of major cardiovascular problems drop 45 percent  compared with women who did none, scientists reported December 3 in the  British Journal of Sports Medicine . And those short bursts of activity can be  really  short, says Emmanuel Stamatakis, a physical activity epidemiologist at the University of Sydney — just 20 to 30 seconds of intense physical exertion sprinkled multiple times throughout the day. In his team’s study, a few minutes total of these bursts was enough to see hefty heart benefits. It’s not a new idea for Stamatakis, who has been working in the field for decades. He’s previously shown that short bouts of vigorous activity  cut the risk of death from any ...

A new battery starves cancer cells of oxygen in mice

The device gives treatments for tumors a boost in lab animals. Solid tumors, such as those formed in breast cancer (SEM image of breast cancer cells shown), can be low-oxygen environments. A new battery wraps around tumors and further deprives them of oxygen. STEVE GSCHMEISSNER/SCIENCE PHOTO LIBRARY/Getty Images It’s not great when a person sucks all the oxygen out of a room. When a battery does it to a tumor, though, it could be a good thing. A tiny self-charging battery wrapped around a tumor removes oxygen from the cancer cells’ environment, boosting the power of some cancer therapies, a study in mice shows. Mice that had small batteries wrapped around their breast cancer tumors, combined with cancer therapy, showed a  90 percent decrease in tumor volume  in two weeks, researchers report March 31 in  Science Advances .  Solid tumors, such as  those that can develop in breast cancer , often grow rapidly — so rapidly that the tumor’s growth is faster than its b...

The spread of breast cancer may be inherited

-
Image
A variant of the gene  PCSK9   may spur breast cancer’s spread. An approved antibody might stop it. A commonly inherited version of the  PCSK9  gene may spur breast cancer cells to migrate to other parts of the body (metastasis illustrated). The gene is known for its role in raising cholesterol, and there's already a lab-made antibody for treating it that may also stop the cancer spread. Wildpixel/iStock/Getty Images Plus A gene involved in setting cholesterol levels may also determine whether breast cancer spreads to other parts of the body. A variant of the  PCSK9  gene  drives the spread of breast cancer , but a lab-made antibody already approved to treat high cholesterol may help stop the exodus, researchers report December 9 in  Cell . For years, researchers have been examining normal tissue and breast cancer tumors that had spread to other parts of the body trying — and failing — to find mutations that spur the migration, says oncologist and...
