People who can’t visualise an image in their mind’s eye are less likely to remember the details of important past personal events or to recognise faces, according to a review of nearly ten years of research. People who cannot bring to mind visual imagery are also less likely to experience imagery of other kinds, like imagining music, according to new research by the academic who first discovered the phenomenon. Professor Adam Zeman, of the University of Exeter, first coined the term aphantasia in 2015, to describe those who can’t visualise. ...

From pacemakers to neurostimulators, implantable medical devices rely on batteries to keep the heart on beat and dampen pain. But batteries eventually run low and require invasive surgeries to replace. To address these challenges, researchers in China devised an implantable battery that runs on oxygen in the body. The study, published March 27 in the journal Chem, shows in rats that the proof-of-concept design can deliver stable power and is compatible with the biological system. “When you think about it, oxygen is the source of our life,” says corresponding author Xizheng Liu, who specializes in energy materials and devices at Tianjin University of Technology. “If ...

Researchers Toru Miyamoto, Ko Mochizuki, and Atsushi Kawakita of the University of Tokyo have discovered the first species pollinated by sap beetles in the genus Pandanus, a group of palm-like plants native to the tropics and subtropics of Africa and Eurasia. The discovery overturned the long-held belief that these plants were pollinated by wind. The researchers also found that fragrant screw pines’ male and female flowers produced heat at night stably, making them the first such species in the family Pandanaceae. The findings were published in ...

A new Kaiser Permanente study found that a health coaching intervention successfully reduced sitting time for a group of older adults by just over 30 minutes a day. Study participants also showed meaningful improvements in blood pressure, comparable to the effect of other interventions focused on physical activity.  The study was published March 27 in JAMA Network Open and included 283 Kaiser Permanente Washington members aged 60-89. Older adults typically sit for between 65 and 80 percent of the hours that they are awake, and strong evidence shows that ...

McGill researchers have discovered a safer and more efficient technique for testing new drugs while they are in development. “Because this approach is so much more streamlined, it could help accelerate this step in the drug development process and make it less dangerous, since probing the distribution and fate of a drug in the body is required for any pharmaceutical candidate to be approved,” says Bruce A. Arndtsen, a James McGill Professor who teaches in the Department of Chemistry at McGill and is the senior author on the paper describing the new process, published recently in Nature Chemistry. “This research replaces what can be a days’ long, dangerous and ...

FRANKFURT. In 2022, scientists of the EHT unveiled the first image of Sgr A* – which is approximately 27,000 light-years away from Earth – revealing that the Milky Way’s supermassive black hole looks remarkably similar to M87’s, even though it is more than a thousand times smaller and less massive.  This made scientists wonder whether the two shared common traits outside of their looks. To find out, the team decided to study Sgr A* in polarized light. Previous studies of light around M87* had shown that the magnetic fields around the gigantic black hole allowed it to launch powerful jets of material back into the surrounding environment. ...

Imagine being middle aged and starting to feel that you are off balance a lot and that you are having a hard time coordinating your movements. Those are among the symptoms of Spinocerebellar ataxia type 6, known as SCA6, a rare neurodegenerative disease which typically appears in adulthood and worsens over time. Over time, other problems such as slurred speech and difficulty seeing or seeing double, may also appear. It is estimated that fewer than 5,000 people in the US have the condition, which is the result of genetic mutations in the cerebellum. The disease currently has no cure. But this may change, thanks to a new discovery made by McGill researchers. In ...

Elevated surface ozone concentrations in China are posing a significant threat to both human health and crop yields. Extreme heat can greatly exacerbate ozone pollution through both complex chemical and physical processes. For example, extreme heat is often accompanied by stagnant weather conditions, which can lead to the accumulation and subsequent elevation of ozone. Considering that extreme heat events have been becoming increasingly frequent in recent decades, and are also expected to do so on into the future, effective control strategies to reduce ozone pollution risks are urgently needed. Therefore, a research group led by Prof. Ke ...

AURORA, Colo. (March 27, 2024) – Researchers have identified a protein that, when targeted, enables cisplatin-resistant cancer cells to become responsive to treatment. Cisplatin, and other similar platinum drugs, are incredibly effective at killing rapidly growing cancer cells, which is why they have been used in treating cancers for over 45 years. However, these drugs are non-targeted and can cause debilitating toxic side effects, resulting in a diminished lifestyle, and patients in poor health are deemed ineligible for use. In a study, published today in Cancer Research, a journal of the American Association for Cancer Research, researchers say they ...

Dedicated memory tests on smartphones enable the detection of “mild cognitive impairment”, a condition that may indicate Alzheimer’s disease, with high accuracy. Researchers from DZNE, the Otto-von-Guericke University Magdeburg and the University of Wisconsin-Madison in the United States who collaborated with the Magdeburg-based company “neotiv” report these findings in the scientific journal npj Digital Medicine. Their study is based on data from 199 older adults. The results underline the potential of mobile apps for Alzheimer’s disease research, clinical trials and routine medical care. The app that ...

Washington, D.C.—With resistance to chemical antibiotics on the rise, the world needs entirely new forms of antibiotics. A new study published in Microbiology Spectrum, a journal of the American Society for Microbiology, shows that an enzymatic cocktail can kill a variety of mycobacterial species of bacteria, including those that cause tuberculosis. The research was carried out by scientists at Colorado State University and Endolytix Technologies. “We have a mycobacterial drug that works for Nontuberculous Mycobacteria and M. tuberculosis that is biological, not phage therapy, and not small molecule antibiotics,” said Jason Holder, Ph.D., a study coauthor ...

New research from Cedars-Sinai suggests people who are scheduled for certain medical procedures should stop taking popular weight loss drugs in the days or weeks prior to avoid complications. Investigators found glucagon-like peptide-1 receptor agonists (GLP-1RAs) —medications like Ozempic and Wegovy that are used to treat diabetes and obesity—are associated with an increased risk of aspiration pneumonia following endoscopy. The large, population-based study is published in the leading ...

SOMERVILLE, TEXAS, March 27, 2024- The Pecan Breeding and Genetics Program of the U.S. Department of Agriculture's Agricultural Research Service (USDA-ARS) recently completed a $2.5 million laboratory modernization to accelerate pecan breeding through innovations in genetics and plant disease research. A ribbon-cutting ceremony was held on March 26 to commemorate the completion of the project. Pecan trees represent North America's native nut tree and a multimillion-dollar crop. These trees have been cultivated commercially for less than 150 years. It takes an average of 28 years from planting ...

Liver disease is a major health concern, causing millions of deaths worldwide each year. One serious complication is liver fibrosis, scarring that can lead to liver failure. There is currently no effective treatment, but new research suggests promise for exosomes, tiny sacs released by cells. Non-parenchymal cells like hepatic stellate cells (HSCs), Kupffer cells (KCs), and liver sinusoidal endothelial cells (LSECs) play a key role in fibrosis development. These cells are involved in inflammation, scar formation, and tissue repair. Understanding ...

Flexible solar cells have many potential applications in aerospace and flexible electronics, but low energy conversion efficiency has limited their practical use. A new manufacturing method has increased the power efficiency of flexible solar cells made from perovskite, a class of compounds with a specific crystalline structure that facilitates the conversion of solar energy into electricity.   Current flexible perovskite solar cells (FPSCs) suffer from lower power conversion efficiency than ...

A new image from the Event Horizon Telescope (EHT) collaboration— which includes scientists from the Center for Astrophysics | Harvard & Smithsonian (CfA)— has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new view of the monster lurking at the heart of the Milky Way Galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the center of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes. This similarity also hints toward a hidden ...

People with specific genetic traits and those who have anxiety or depression have a significantly higher heart attack risk during periods of social or political stress than at other times, according to a new study being presented at the American College of Cardiology’s Annual Scientific Session. Researchers said the findings suggest opportunities to identify those at elevated risk and perhaps even prevent cardiac events. Doctors have long noticed that heart attacks tend to spike around certain times, such as the winter holidays, but the reasons ...

Young adults who were prescribed stimulant medications for attention-deficit/hyperactivity disorder (ADHD) were significantly more likely to develop cardiomyopathy (weakened heart muscle) compared with those who were not prescribed stimulants, in a study presented at the American College of Cardiology’s Annual Scientific Session. The study found that people prescribed stimulants such as Adderall and Ritalin were 17% more likely to have cardiomyopathy at one year and 57% more likely to have cardiomyopathy at eight years compared with those who were not taking these medications. Cardiomyopathy involves structural ...

Sleeping fewer than seven hours is associated with a higher risk of developing high blood pressure over time, according to a study presented at the American College of Cardiology’s Annual Scientific Session. While the association between sleep patterns and high blood pressure has been reported, evidence about the nature of this relationship has been inconsistent, according to researchers. The current analysis pools data from 16 studies conducted between January 2000 and May 2023, evaluating hypertension incidence in 1,044,035 people from six countries who did not have a prior history of high blood pressure over a median follow-up of five years (follow-up ranged from 2.4 to 18 years). ...
