Gene-based blood test for melanoma may catch early signs of cancer’s return
2025-04-15
Monitoring blood levels of DNA fragments shed by dying tumor cells may accurately predict skin cancer recurrence, a new study shows.
Led by researchers at NYU Langone Health and its Perlmutter Cancer Center, the study showed that approximately 80% of stage III melanoma patients who had detectable levels of circulating tumor DNA (ctDNA) before they started treatment to suppress their tumors went on to experience recurrence.
The researchers also found that the disease returned more than four times faster in this group than in those with no detectable levels of the biomarker, and the higher ...
Common genetic variants linked to drug-resistant epilepsy
2025-04-15
Certain common genetic changes might make some people with focal epilepsy less responsive to seizure medications, finds a new global study led by researchers at UCL and UTHealth Houston.
Focal epilepsy is a condition where seizures start in one part of the brain. It is the most common type of epilepsy.
Antiseizure medication is usually prescribed for people with the condition. However, for one in three people with epilepsy (around 20 million individuals worldwide), current antiseizure medications are ineffective. This means ...
Brisk walking pace + time spent at this speed may lower risk of heart rhythm abnormalities
2025-04-15
A brisk walking pace, and the amount of time spent at this speed, may lower the risk of heart rhythm abnormalities, such as atrial fibrillation, tachycardia (rapid heartbeat), and bradycardia (very slow heartbeat), finds research published online in the journal Heart.
The findings were independent of known cardiovascular risk factors, but strongest in women, the under 60s, those who weren’t obese, and those with pre-existing long term conditions.
Heart rhythm abnormalities (arrhythmias) are common, note the authors, with atrial fibrillation ...
Single mid-afternoon preventer inhaler dose may be best timing for asthma control
2025-04-15
A single daily preventer dose of inhaled corticosteroid (beclomethasone), taken mid afternoon, may be the best timing for effective asthma control as it suppresses the usual nocturnal worsening of symptoms more effectively than dosing regimens at other times of the day, suggest the results of a small clinical trial published in the journal Thorax.
If the findings are confirmed in larger studies, this approach may lead to better clinical outcomes for patients without increasing unwanted steroidal ...
Symptoms of ice cold feet + heaviness in legs strongly linked to varicose veins
2025-04-15
Hypersensitivity to the cold, especially ice cold feet, as well as a feeling of heaviness in the legs, are linked to the presence of varicose veins, finds a large study published in the open access journal Open Heart.
Cold hypersensitivity is often underestimated as a subjective symptom, say the researchers.
Varicose veins are usually caused by impaired functioning of the deep or superficial veins, and the perforator veins (short veins that link the superficial and deep venous systems in the legs).
The prevalence of varicose veins ranges from 2% to 30% in adults, with women at higher risk. And symptoms include sensations ...

To determine which brain areas are necessary for a certain ability, researchers study patients with brain lesions (an area of damage in the brain) caused by stroke or brain tumours. This approach, known ...
Growing wildflowers on disused urban land can damage bee health
2025-04-15
Wildflowers growing on land previously used for buildings and factories can accumulate lead, arsenic and other metal contaminants from the soil, which are consumed by pollinators as they feed, a new study has found.
The metals have previously been shown to damage the health of pollinators, which ingest them in nectar as they feed, leading to reduced population sizes and death. Even low nectar metal levels can have long-term effects, by affecting bees’ learning and memory - which impacts their foraging ability.
Researchers have found that common plants including white clover and bindweed, which ...
Rapid rise in vaping in Britain has stalled
2025-04-15
The study, published in the journal Addiction and funded by Cancer Research UK, looked at survey data on vaping habits in England, Wales and Scotland before and after the UK Government announced plans to restrict vaping, including by banning disposable vapes, in January 2024.
The team found that the proportion of people vaping increased by nearly a quarter each year from January 2022 to January 2024, but stayed constant between January 2024 and January this year, including for young people.
After January 2024, they also found a substantial decline in the proportion of vapers mainly using disposable e-cigarettes. Among 16- to 24-year-olds, the proportion ...

New study reveals how to make prescribed forest fires burn safer and cleaner
2025-04-15
Prescribed burns literally fight fire with more fire. Often referred to as a “beneficial fire,” they target areas at risk for wildfires and burn away material that could otherwise fuel a future blaze.
However, all fires, whether accidental or planned, produce smoke that can cause health and respiratory issues, especially in nearby communities. Burning fires release harmful chemicals, like polycyclic aromatic hydrocarbons (PAHs), that are carcinogenic – PAHs can cause cancer, lung damage, and lead to weakened immunity in those who inhale smoke.
Recently, in a study published in Atmospheric ...
Inactive components in agricultural runoff may be hidden contributors to drinking water hazards
2025-04-15
Inactive ingredients in agricultural, pharmaceutical and other common products have typically been excluded from consideration as potential contaminants in drinking water. However, while these chemicals are inert in certain products, they still can pose hazards when combined with other materials during the drinking water treatment process.
A new study from researchers in the McKelvey School of Engineering at Washington University in St. Louis reveals how large this impact might be. Jean Brownell, a graduate student working with Kimberly Parker, associate professor of energy, environmental & chemical engineering, ...
Colombia’s peatlands could be a crucial tool to fight climate change. But first we have to find them
2025-04-15
UC Santa Cruz Assistant Professor of Environmental Studies Scott Winton has been wading through thick, smelly muck in the tropics for almost a decade. He wouldn’t have it any other way. As a wetland ecologist and biogeochemist, he’s been hard at work investigating an important and mysterious topic: peatlands.
Peatlands are a special type of wetland with enormous potential to either help or hurt global efforts to address climate change. If we want peatlands on our side, we’ll have to protect them. But that’s difficult to do, since we still don’t ...

Unlocking faster orthodontic treatments: the role of atf6 in bone remodeling
2025-04-15
Orthodontic treatments often take years, but a breakthrough discovery could drastically shorten this period. Researchers have uncovered that ATF6, a protein activated in macrophages during corticotomy, accelerates tooth movement by promoting inflammation and boosting the production of TNFα, a key factor in bone remodeling. This finding paves the way for faster, more efficient orthodontic procedures, minimizing both treatment time and patient discomfort. The study highlights the potential for non-invasive therapies that could reshape the future of orthodontic care.
Corticotomy, a surgical procedure aimed at accelerating tooth movement, ...

Uncovering the molecular drivers of liver cancer
2025-04-15
Liver cancer can arise spontaneously from healthy liver tissue. Recently, however, researchers have discovered an increasing correlation between some liver cancers and non-viral chronic liver disease (CLD).
One liver cancer, hepatocellular carcinoma (HCC), is associated with CLD in about 15–25% of cases. While increasing awareness and screening of cancers has improved the ability to detect liver cancer at earlier stages when it is more effectively treated, cancer prevention is always a primary goal of both healthcare providers and biomedical researchers.
The increasing prevalence of ...
