Best region for life on Mars was far below surface

A Rutgers-led study suggests the most habitable region for life on Mars would be up to several miles below its surface due to subsurface melting of thick ice sheets. Liquid water may have been stable at great depths, allowing life to thrive through hydrothermal activity and rock-water reactions.

Birth defects linked to greater risk of cancer in later life

A study published in The BMJ found that people born with major birth defects face a higher risk of cancer throughout life. The relative risk is greatest in childhood, but the risk persists into adulthood. Major birth defects are associated with an increased risk of various types of cancer, including leukemia.

Combined exercise, mindfulness training may help reduce fatigue in cancer survivors

Researchers at the University of Illinois Urbana-Champaign have found that combining exercise and mindfulness training can significantly reduce fatigue in breast cancer survivors. The study used a feasibility trial with 40 women, who reported a drop in fatigue levels after participating in a combination of both interventions.

What's killing killer whales?

A decade-long study of killer whale necropsies reveals widespread mortality linked to human activities, affecting all age classes. Human-caused deaths were found in healthy populations as well as endangered species, emphasizing the need for improved conservation strategies.

Research suggests our galaxy's brightest gamma-ray binary system may be powered by a magnetar star

A team of researchers has analyzed data to infer the nature of compact object orbiting within LS 5039, the brightest gamma-ray binary system in the Galaxy. The team suggests that particle acceleration process is caused by interactions between dense stellar winds and ultra-strong magnetic fields of a rotating magnetar.

Brexit opens the door to tougher anti-smoking measures

A new study suggests that a no-deal Brexit could raise cigarette and tobacco prices in the UK, making it easier to implement effective tobacco control measures. The research also highlights the potential benefits of Brexit for tackling smoking, including reduced smuggling and increased revenue for the government.

Anti-doping education: Teaching athletes about morality in sport can help reduce doping

Researchers developed two intervention programmes targeting moral factors and educating young elite athletes about the risks of performance-enhancing drugs. Both approaches were equally effective at deterring doping over a six-month period. The 'moral' programme focused on honesty, fair play, and the consequences of doping, while the '...

Researchers determine how the SARS-CoV-2 virus hijacks and rapidly causes damage to human lung cells

The study reveals that the SARS-CoV-2 virus rapidly causes damage to human lung cells by exploiting core resources and inducing abnormal changes in protein abundance and phosphorylation. The researchers also identified 18 pre-existing clinically approved drugs that can be potentially re-purposed for COVID-19 therapy.

SMART researchers develop plant nanobionic sensor to monitor arsenic levels in soil

Scientists from SMART DiSTAP have engineered a novel type of plant nanobionic optical sensor that can detect and monitor arsenic levels in the belowground environment. This non-destructive approach enables plants to serve as self-powered detectors of arsenic, marking a significant upgrade over conventional methods.

Environmental exposures affect therapeutic drugs

Researchers from the University of Vienna used high-resolution mass spectrometry to analyze environmental toxin interactions with therapeutics. The study found that exposure to substances like BPA and genistein can alter drug efficacy, leading to reduced effectiveness in cancer treatment and other conditions.

New childhood dementia insight

Researchers have discovered a potential window to the brain in Sanfilippo syndrome, a rare and untreatable form of childhood-onset dementia. The study uses retinal imaging techniques to monitor disease progression and therapeutic efficacy, providing new hope for patients.

Seismic activity of New Zealand's alpine fault more complex than suspected

Research suggests that some parts of the Alpine Fault, particularly around Hokitika and Greymouth, may experience strong ground shaking more often than previously thought. The study found evidence of a 19th-century earthquake along the fault's northeastern end, indicating that smaller earthquakes could occur between large rupture events.

Octogenarian snapper found in WA becomes oldest tropical reef fish by two decades

An 81-year-old midnight snapper caught off the coast of Western Australia has become the oldest recorded tropical reef fish, surpassing the previous record by two decades. The study found that long-lived fish are generally considered vulnerable to fishing pressure, highlighting the need for sustainable management of commercial fisheries.

Statins can save lives, are they being used?

A recent study found that only about 60% of patients with coronary artery disease, stroke, or peripheral artery disease receive the recommended statin therapy. Despite a decrease in drug cost, disparities persist in statin use among different age groups, genders, and racial backgrounds.
