A dysfunction in muscle blood vessels could be to blame for the weak muscles and weight loss that most cancer patients experience, according to a new study from University of Illinois Chicago researchers. The discovery may help cancer survivors regain their muscle strength, which could contribute to better outcomes for these patients, said Dr. Jalees Rehman, senior author of the new paper and the Benjamin J. Goldberg Professor and head of the department of biochemistry and molecular genetics at the College of Medicine. Up to 80% of patients with cancer experience muscle ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Nagoya University scientists and their collaborators have used Japan's extensive network of Global Navigation Satellite System (GNSS) receivers to create the first 3D images of atmospheric disturbances caused by the 2024 Noto Peninsula Earthquake. Their results show sound wave disturbance patterns in unique 3D detail and provide new insights into how earthquakes generate these waves. The results were published in the journal Earth, Planets and Space. Mapping electron density ...

A new deep learning-based approach has been developed to overcome one of the critical limitations in fluorescence microscopy: severe image degradation caused by noise in dynamic in vivo imaging environments. The technique, recently published in PhotoniX (May 23, 2025), introduces a self-supervised denoising network—TeD (Temporal-gradient empowered Denoising)—that improves image quality without requiring clean reference images, representing a breakthrough for applications involving rapid biological ...

More than three decades ago, the U.S. Food and Drug Administration (FDA) approved Bacillus Calmette-Guérin (BCG) as the first immunotherapy against cancer. And it is still used today to treat early-stage bladder cancer. Now, a team of researchers from Memorial Sloan Kettering Cancer Center (MSK) and Weill Cornell Medicine is expanding the understanding of how the treatment works — an understanding that could help improve the effectiveness of immunotherapies more broadly. BCG is a weakened strain of the bacterium Mycobacterium bovis, which is used worldwide as a vaccine against childhood tuberculosis. ...

Immediate recovery efforts receive the most attention after severe natural disasters, yet new data from researchers at Drexel University and the University of Maryland suggests these climate events often also leave a critical long-term — and often unaddressed — problem in declines in access to health care. The team found a statistically significant link between severe natural disasters, such as heatwaves, droughts, floods and wildfires, and loss of health care infrastructure — including hospitals and outpatient ...

Tsukuba, Japan—Due to the sudden rupture of the aortic wall, aortic dissection is a life-threatening condition that requires immediate medical attention, as it can lead to vascular collapse. Individuals with inherited connective tissue disorders, such as Marfan syndrome, are particularly at risk, often developing the condition at a young age. This highlights the urgent need for effective preventive and therapeutic strategies. However, the molecular mechanisms that drive the onset and progression of aortic dissection remain poorly understood. In a recent study, an international research team led by the University of Tsukuba created a mouse ...

Most experts and those experiencing the potentially debilitating features of Polycystic Ovary Syndrome (PCOS), which affects one in eight women, want greater awareness and a name change to improve care and outcomes. A new Monash University-led research paper reveals those involved are keen to overcome the misleading implication that it is only an ovarian or gynaecological condition. PCOS carries risks of higher body weight, diabetes, heart disease, fertility issues and pregnancy complications, endometrial cancer, ...

Monarch butterflies are famous for their annual migrations, but not all migrate. In recent years, more and more monarchs have been living and breeding year-round in California’s Bay Area, thanks in part to the growing presence of non-native milkweeds in urban gardens. In a new study published in Ecosphere, University of California, Davis, researchers show that these resident butterflies are not connected to the larger population of monarchs known for their late-autumn coastal migrations. Their work suggests that resident monarchs and the non-native milkweeds that sustain them are ...

Researchers gave participants face tattoos that can track when their brain is working too hard. Published May 29 in the Cell Press journal Device, the study introduces a non-permanent wireless forehead e-tattoo that decodes brainwaves to measure mental strain without bulky headgear. This technology may help track the mental workload of workers like air traffic controllers and truck drivers, whose lapses in focus can have serious consequences. "Technology is developing faster than human evolution. Our brain capacity cannot keep up and can easily get ...

About The Study: The findings of this study that fewer than half of U.S. adults are aware and about one-fifth are unsure of their awareness of the association between alcohol and cancer emphasize the need to implement the recently updated Surgeon General’s recommendation to reduce the alcohol-related cancer burden in the U.S. Corresponding Author: To contact the corresponding author, Sanjay Shete, PhD, email sshete@mdanderson.org.

University of Virginia School of Medicine scientists have uncovered a key reason why HIV remains so difficult to cure: Their research shows that small changes in the virus affect how quickly or slowly it replicates, and how easily or stubbornly it can reawaken from hiding. These insights bring researchers closer to finding ways to flush out the dormant virus and eliminate it for good. Thanks to remarkable progress in HIV treatment, the virus can often be suppressed to undetectable levels in the blood, eliminating most disease symptoms, and preventing transmission to others. But HIV never truly ...

Kyoto, Japan -- Whether you are lucky enough to have a cat companion or must merely live this experience vicariously through cat videos, Felis catus is a familiar and comforting presence in our daily lives. Unlike most other feline species, cats exhibit sociality, can live in groups, and communicate both with other cats and humans, which is why they have been humans' trusted accomplices for millennia. Despite this intimacy, there is still much that we don't know about our feline friends. Numerous behavioral studies have been conducted on other mammal species, but relatively few on cats. In part to fill this gap, a team of researchers at ...

The global measles outbreak must trigger an urgent debate into whether a vaccine should be recommended earlier to better protect against the highly contagious disease during infancy, a new review states. The systematic review, led by Murdoch Children’s Research Institute (MCRI), found vaccinating children from as early as four months of age for measles warranted serious discussion given that only 30 per cent of babies in low- and middle-income countries were protected by maternal antibodies by four months of age. Concerningly, this is well below the World Health Organization’s (WHO) recommendation of a first measles dose between 9-12 months old. The ...

Rising atmospheric CO2 levels from fossil fuel dependence have intensified climate threats, driving demand for technologies that convert CO2 into value-added chemicals. Electrocatalytic CO2 reduction (CO2RR) holds promise but faces challenges such as high energy costs, low product selectivity, and competition from hydrogen evolution reactions (HER). A breakthrough by researchers at Tongji University, China, introduces a new catalyst design that overcomes these limitations, paving the way for green chemistry solutions.   The ...

Herndon, VA, May 29, 2025 – Many policy discussions on AI safety regulation have focused on the need to establish regulatory “guardrails” to protect the public from the risks of AI technology. In a new paper published in the journal Risk Analysis, two experts argue that, instead of imposing guardrails, policymakers should demand “leashes.”   Director of the Penn Program on Regulation and professor at University of Pennsylvania Carey Law School, Cary Coglianese and University of ...

High levels of income inequality weaken support for raising the minimum wage, which in turn could further worsen income inequality as people believe this is the way things should be, according to research published by the American Psychological Association.  The researchers analyzed data from more than 130,000 protests across the country and conducted eight other experiments that found that an “is-to-ought” reasoning error may be to blame where people view situations as they are and then infer that is the way they should be. That can have ...

Lateral walking exercise is beneficial for the hip abductor enhancement. Accurate gait recognition and continuous hip joint angle prediction are essential for the control of exoskeletons. “The hip exoskeleton is a promising tool for enhancing muscle activation during lateral walking exercises by providing controlled resistance a support. This ensures adequate muscle exercise for effective rehabilitation. Our team has previously designed a resistance lateral walking exercise exoskeleton. Accurate gait recognition and continuous joint angle prediction are the precondition of the good control performance of the exoskeleton.” Explained study author Wujing Cao, a professor at Chinese ...
