Researchers chronicle lifetime travels of a single woolly mammoth which wandered the north more than 14,000 years ago

A female woolly mammoth named Élmayuujey'eh travelled hundreds of kilometres through northwestern Canada and Alaska before encountering early people crossing the Bering Land Bridge. The study's findings suggest that human activity may have indirectly affected mammoth populations by curtailing their movements and access to grazing areas.

New research finds half-cardio, half-strength training reduces cardiovascular disease risks

Researchers at Iowa State University found that a combination of aerobic and resistance exercises reduces cardiovascular disease risks as much as aerobic-only regimens. The study, which involved 406 participants, showed significant decreases in body fat percentage across all exercise groups compared to the no-exercise control group.

Rain can spoil a wolf spider’s day, too

Researchers found that wolf spiders can't easily signal others or perceive danger from predators on rain-soaked leaves compared to dry ones. Male spiders use visual and vibratory signals for courtship, but vibrations are better received in dry leaves.

Tiny AI-based bio-loggers revealing the interesting bits of a bird’s day

Researchers from Osaka University have developed a small sensor-based data logger that automatically detects and records video of infrequent behaviors in wild seabirds. The bio-logger uses low-power sensors and artificial intelligence to capture rare behaviors, such as head-shaking and foraging habits, without needing human supervision.

Healing heel pain: researchers from Sahmyook University explore the use of local vibration in plantar fasciitis treatment

A recent trial assessed a novel combination of local vibration and extracorporeal shock wave therapy for the effective treatment of plantar fasciitis, with results showing significant reductions in plantar fascia thickness and heel pain. The study highlights a promising therapeutic intervention to treat this common musculoskeletal cond...

Winding down the window, drinking tea and coffee, turning the radio up and singing while driving could be signs of a dangerous snoring condition

Researchers found that people with OSA were more likely to use multiple strategies to stay alert while driving, which can indicate excessive sleepiness. This study suggests that asking about these coping strategies in the clinic could help doctors identify patients at risk of driving incidents and advise them appropriately.

Researchers identify key characteristics associated with improved CAR T outcomes in large B cell lymphoma

Researchers identified key characteristics associated with improved CAR T outcomes in large B cell lymphoma, including a B-cell gene expression signature and high CD19 protein expression. Patients who received axicabtagene ciloleucel had better event-free survival compared to those receiving standard therapy.

Ditches and ponds can be the sources or sinks of non-point source pollution: observations in an upland area in the Jinglinxi catchment, China

Research found that ditches and ponds in the Jinglinxi catchment can be both sources and sinks of agricultural pollutants. The study suggests retaining sediment in ditches during dry seasons and cleaning it in rainy seasons to maximize their ecological role.

Metastatic breast cancer treatments have aided decline in deaths, Stanford Medicine-led study finds

A Stanford Medicine-led study found that advances in treating metastatic breast cancer are responsible for nearly one-third of the decrease in annual deaths from breast cancer between 1975 and 2019. This decline is attributed to improved treatments, which have enabled women with metastatic disease to live longer than ever.

Surprisingly simple model explains how brain cells organize and connect

Researchers propose a simple model that accurately describes neuronal connectivity in various organisms, suggesting that general networking principles govern brain organization. The model also provides an unexpected explanation for clustering phenomenon in social interactions and can be extended to other types of networks.

Older adults who exercise with their spouse may be less physically active than those who exercise individually, finds NTU Singapore study

A study by NTU Singapore researchers found that older adults who exercise with their spouse achieve lower physical activity levels. Personalised fitness feedback from trackers increased physical activity in these individuals, suggesting it may be more effective to encourage older adults to exercise individually.

Infusion of bone marrow mononuclear cells results in decreased intensive care needs and white matter preservation for children with severe traumatic brain injury

Researchers found that bone marrow mononuclear cell infusion in children within 48 hours of severe traumatic brain injury reduced intensive care needs and preserved white matter. The treatment also enhanced connectivity in the corpus callosum, a midline structure in the brain.
