Short-term hormone therapy plus radiation therapy increases survival for men with early-stage prostate cancer

A new study published in the New England Journal of Medicine found that combining short-term hormone therapy (ADT) with radiation therapy significantly improves overall survival rates for men with intermediate-risk prostate cancer. The treatment also resulted in a 10% reduction in disease-specific deaths among high-risk patients.

Climate adaptation of rice

Researchers discovered that colonizing rice plants with fungal spores from naturally salt-tolerant plants enhances their ability to withstand cold, salt, and drought. This emerging strategy, called symbiogenics, could help mitigate climate change impacts on global food security.

HPV infection highly prevalent among organ transplant recipients

A study of 210 organ transplant recipients with previous SCC found that BetaPV infection is extremely common, with concordant presence of DNA and antibodies increasing the risk for SCC skin cancer. The findings may lead to novel preventative or therapeutic interventions for immunosuppressed individuals.

Brainy lizards pass test for birds

Researchers at Duke University found that tropical anoles can solve novel problems and remember solutions, demonstrating advanced cognitive abilities. The study's results challenge the notion that reptiles have limited cognitive capabilities and highlight the complexity of animal cognition.

When it comes to population growth, Houston is No. 1

Houston's population growth was the highest in the US, with a whopping 1.2 million new residents added over the past decade, outpacing New York and Chicago combined. The city's growth can be attributed to its proximity to Latin America, business-friendly policies, low cost of living, and significant job growth.

Study: People at risk for panic buffered from stressor by high levels of physical activity

A recent study published in Psychosomatic Medicine found that individuals with high anxiety sensitivity exhibited reduced anxiety reactivity when engaging in high levels of physical activity. Regular exercise was shown to be an effective alternative or complementary strategy to traditional treatments for depression and anxiety problems.

Alternative methods of smear collection are effective at diagnosing TB

Researchers developed alternative smear collection methods that are more convenient for patients, yet maintain the same level of accuracy for diagnosis. The findings suggest that a single patient visit could be sufficient to diagnose pulmonary tuberculosis, improving access to treatment, particularly in poor countries.

Biomarker for autism discovered

Researchers at the University of Cambridge identified a biomarker for autism in siblings of individuals with autism, showing reduced brain activity to emotional facial expressions. This finding provides an opportunity to investigate genes linked to autism and sheds light on why some family members are more affected than others.

Last dinosaur before mass extinction discovered

Researchers at Yale University found a ceratopsian horn fossil buried just five inches below the K-T boundary, suggesting that dinosaurs did not go extinct prior to the impact. The discovery provides further evidence for the impact hypothesis and may have closed the 'three-meter gap' in the fossil record.

Low dose naltrexone (LDN): Harnessing the body's own chemistry to treat human ovarian cancer

Researchers at The Pennsylvania State University College of Medicine discovered that low-dose naltrexone (LDN) has a potent antitumor effect on human ovarian cancer. Combining LDN with chemotherapy resulted in an additive inhibitory action on tumorigenesis, reducing DNA synthesis and cell replication.

Severity of spinal cord injury has no impact on how adults rate their health, WSU research finds

A study by Wayne State University researchers found that self-rated physical ability tops injury severity as a determining factor of health ratings in adults with spinal cord injuries. The study suggests that people with disabilities can still rate their health as excellent or good despite being confined to a wheelchair or paralyzed.

Researchers study pesticide pathways into the atmosphere

Researchers discovered herbicide volatilization consistently results in losses exceeding those from surface runoff, with a significant impact on groundwater contamination. The study highlights the importance of considering soil moisture levels and air temperatures in models of pesticide volatilization.

Supramolecules get time to shine

Researchers developed a supramolecular system combining single-walled carbon nanotubes with porous silicate materials, enabling the study of interactions between carbon nanotubes and a wide range of photoluminescent molecules. The platform holds promise for applications in catalysis, artificial photosynthesis, and hydrogen splitting.
