Researchers solve the mystery of the bird from Atlantis

A new study by Lund University researchers has found that the Inaccessible Island rail, also known as Atlantisia, flew to its island habitat from South America around 1.5 million years ago. This discovery contradicts a previous theory suggesting the bird's inability to fly was an ancient trait.

Workers without paid sick leave endure significant financial worries

A study by researchers at Florida Atlantic University and Cleveland State University found a positive association between not having paid sick leave and reporting financial worry. Workers without paid sick leave were more likely to worry about short-term financial issues like housing expenses, as well as long-term financial issues such...

Fishing for new leads in a rare melanoma

Zebrafish models have been developed to study the intricate molecular pathways underlying mucosal melanomas. The research identified a previously unrecognized tumor suppressor, SPRED1, and its interplay with oncogene KIT. These findings hold promise for developing precision cancer therapies for this rare and aggressive form of melanoma.

Children who experience violence early in life develop faster

A study published in Biological Psychiatry found that exposure to early life violence accelerates biological aging, including pubertal development, while deprivation-related adversity leads to delayed pubertal development. Children who experienced violence showed signs of accelerated epigenetic aging and increased symptoms of depression.

Yangtze dams put endangered sturgeon's future in doubt

Researchers found that the Yangtze dams have reduced the distance of Chinese sturgeon migration by 1,175 kilometers, leading to delayed maturity and a decline in breeding activity. The environmental capacity of the spawning ground has also been reduced, contributing to the ongoing decline of the species.

How cancer-causing papillomaviruses evolved

Researchers discovered that cancer-causing papillomaviruses diverged from their common ancestors half a million years ago, coinciding with the split between Neanderthals and modern humans. The viruses adapted to specific host ecosystems and then coevolved with primates for at least 40 million years.

Concurrent chemo-radiotherapy should be a treatment option for elderly patients with LS-S

A study published in the Journal of Thoracic Oncology found that elderly patients with limited-stage small cell lung cancer (LS-SCLC) can benefit from concurrent chemo-radiotherapy, similar to younger patients. The analysis showed comparable survival rates and toxicity between older and younger groups, providing robust evidence for tre...

Updated European guidance for the diagnosis and management of osteoporosis in women

The new guidelines review and update the 2013 European guidance for diagnosing and managing osteoporosis in postmenopausal women. Key findings include the importance of evaluating bone microstructure and using FRAX tools in fracture risk assessment, as well as the need for long-term dietary intakes and monitoring drug treatment.

How invading jumping genes are thwarted

Researchers found that reproductive stem cells boost production of non-coding RNA elements to suppress jumping gene activity and activate DNA repair processes, enabling normal egg development. Temperature influences sterility in fruit flies, with a specific temperature range controlling jumping gene invasion intensity.

'Predicting' the origins of mysterious outbreaks using viral RNA

Using a dataset of over 500 single-stranded RNA viruses, researchers developed a model that can predict animal reservoirs and arthropod vectors directly from viral genome sequences. This approach enables faster evaluation than existing methods, which often require years, and could aid in rapid response to emerging infectious diseases.

Diabetes medications may reduce Alzheimer's disease severity

Researchers found that people with Alzheimer's disease who were treated with diabetes drugs showed fewer markers of the disease, including abnormal microvasculature and gene expressions. The study suggests targeting the brain's capillary system could have beneficial effects in Alzheimer's patients, opening opportunities for new therapies.
