Since the time of the ancient Greek physician Hippocrates, cancer has been recognized as being sensitive to heat. Today, this principle forms the basis of hyperthermia treatment—a promising cancer therapy that uses controlled heat to kill tumor cells while sparing healthy ones. Unlike chemotherapy or radiation, hyperthermia works by heating cancerous tissue to temperatures around 50 °C, causing cancer cell death while simultaneously activating the body's immune system against the tumor. This approach holds particular ...

Hyponatremia, or low blood sodium concentration, is typically viewed as a symptomless condition—until recently. A research team led by Professor Yoshihisa Sugimura, including Dr. Haruki Fujisawa, Professor Atsushi Suzuki, Professor Tsuyoshi Miyakawa, and Professor Akihiro Mouri, from Fujita Health University, Japan, has demonstrated that chronic hyponatremia (CHN) can directly cause anxiety-like behaviors in mice by disrupting key neurotransmitters in the brain. Their findings, published online in the journal Molecular Neurobiology on May 14, 2025, reveal that CHN alters monoaminergic signaling in the amygdala, a brain region ...

To reduce greenhouse gas emissions and combat climate change, the world urgently needs clean and renewable energy sources. Hydrogen is one such clean energy source that has zero carbon content and stores much more energy by weight than gasoline. One promising method to produce hydrogen is electrochemical water-splitting, a process that uses electricity to break down water into hydrogen and oxygen. In combination with renewable energy sources, this method offers a sustainable way to produce hydrogen and can contribute ...

A rich and varied mix of microbes in the mouth, particularly bacteria, is not only important for our oral health, but may hold clues for other conditions. A new study led by researchers at NYU Rory Meyers College of Nursing finds that a lower diversity of microbes in the mouth is associated with depression. The mouth is home to between 500 billion and 1 trillion bacteria—the second-largest community of microorganisms in our bodies, after the gut. A growing number of studies point to the connection between the oral microbiome and our overall health, from diabetes to dementia, a relationship thought to be driven by inflammation and disruptions to the immune system. A recent ...

“China virus”, the Chinese virus — at the start of the 2020 pandemic, you likely often encountered this epithet in the media. The use of geographically-based labels to define the disease (COVID-19) and the virus causing it (SARS-CoV-2) had significant consequences on public opinion, fueling and amplifying — sometimes with very serious outcomes — prejudices against specific people and countries, accused of having a causal role in spreading the contagion. The neutral designation COVID-19, proposed for the disease by the WHO in mid-February 2020, was quickly adopted globally. However, ...

Thanks to lab-grown miniature intestines, researchers at Uppsala University have successfully mapped how aggressive Shigella bacteria infect the human gut. The study opens the door to using cultured human mini-organs to investigate a wide range of other serious infections.  Understanding how human-specific bacteria make us sick is challenging, as laboratory animals rarely reflect human physiology. In a new study published in Nature Genetics, researchers show that it is now possible to use cultured mini-organs to map how bacteria colonise the human intestinal mucosa. The team focused specifically on Shigella, a bacterium that causes severe ...

  New Danish research reveals ocean currents as a major source of mercury contamination in the Arctic Despite global reductions in mercury emissions, mercury concentrations in Arctic wildlife continue to rise. A new study published in Nature Communications by researchers from Aarhus University and the University of Copenhagen reveals that ocean currents may be transporting legacy mercury pollution to the Arctic—posing a long-term threat to ecosystems and human health. “We’ve ...

A new molecule that lets energy hop around quickly within its structure makes the upcycling of light more efficient and tunable. The Kobe University development lays out a design strategy for better solar power harnessing as well as medical and sensor applications. While low-energy light is abundant and harmless, many technical applications from solar power generation to medical treatments rely on high-energy light. To increase the efficiency of light harvesting and to avoid high-energy light as much ...

Taking the progestogen-only contraceptive pill desogestrel continuously for more than five years is associated with a small increased risk of developing a type of brain tumour called an intracranial meningioma, finds a study from France published by The BMJ today. However, the researchers stress that the risk is low compared with some other progestogens (for every 67,000 women taking desogestrel, one might need surgery for meningioma) and disappeared one year after stopping treatment. Intracranial meningiomas are typically non-cancerous brain tumours that occasionally require surgery. ...

The rise in non-prescribed ketamine use across the UK in recent years is a cause for concern, say doctors in The BMJ today. Irene Guerrini at South London & Maudsley NHS Foundation Trust and colleagues warn that its low cost has made it popular among young people, and the number of people starting treatment for ketamine addiction in 2023-2024 reached 3609, more than eight times higher than in 2014-2015. They say public awareness of the risks and long term harms associated with ketamine remains insufficient, and they call for better diagnostic criteria, a ...

A new method improving the accuracy of interpreting blood pressure measurements taken at the ankle could be crucial for people who cannot have their arm blood pressure measured. New research from the University of Exeter Medical School, published in BMJ Open and funded by the National Institute for Health and Care Research (NIHR), analysed data from over 33,000 people to create a personalised predictive model for more accurately estimating arm blood pressure from ankle readings - when compared to previously available methods. The team has developed an online calculator for healthcare professionals and patients to interpret ...

New analysis of the remains of two ‘puppies’ dating back more than 14,000 years ago has shown that they are most likely wolves, and not related to domestic dogs, as previously suggested. The genetic analysis also proved that the cubs were sisters at the age of around two months, and like modern day wolves had a mixed diet of meat and plants. Researchers, however, were surprised to see evidence of a wooly rhinoceros as part of their last meals, as this would have been a considerably large animal for a wolf to hunt. The ‘Tumat Puppies’ are two remarkably well-preserved puppy remains found in northern Siberia, about 40 km from Tumat, the nearest village. One was found ...

EMBARGOED FOR RELEASE UNTIL 4:00 P.M. ET, WEDNESDAY, JUNE 11, 2025 MINNEAPOLIS — Stroke and dementia as well as late-life depression are more common in people who have a biomarker of aging called short leukocyte telomere length, according to a study published on June 11, 2025, online in Neurology®, the medical journal of the American Academy of Neurology. The good news is that this relationship was not found in people with healthy lifestyle habits, such as eating healthy and maintaining low cholesterol and blood pressure. The study does not prove that shorter telomeres cause these brain diseases; it only shows an association.    “Our findings support the potential ...

Scientists from Mass General Brigham explored the associations between telomere length—which decreases as a person ages or is exposed to unhealthy environments—and the risk for age-related brain diseases. The research team found evidence suggesting that healthier lifestyle choices could mitigate telomere length-associated risks. Their results are published in Neurology, the medical journal of the American Academy of Neurology. “Reducing risk factors like weight and alcohol consumption as well as getting more sleep and exercise can all help reverse ...

New editorial in the American Journal of Public Health calls for the renewal of Israeli–Palestinian public health cooperation, even amid the current conflict. Drawing on decades of joint successes—including polio eradication, measles control, maternal health advances, and epidemic surveillance—the editorial urges stakeholders to revive collaborative efforts in critical areas like immunization, environmental health, and hospital rehabilitation. Emphasizing that health partnerships have historically bridged divides, the authors argue against academic boycotts and stress that shared public health is both a moral imperative and a strategic ...

Rutgers Health researchers found that lamotrigine, a widely prescribed antiseizure medication, to be safe in older adults with epilepsy, contrary to a safety warning by the Food and Drug Administration (FDA).   According to the Centers for Disease Control and Prevention, about 2.9 million adults throughout the United States are living with the neurological disorder.   Lamotrigine, sold under the brand name Lamictal, represents about 10% of all antiseizure medication use. In 2020, the FDA placed a safety warning label on lamotrigine based on reports the drug ...
