Information on coastal population growth, seasonal and weekly beach going, surfing, scuba diving, and swimming empowers ocean users to avoid large predators.
A new study reveals surprisingly high geothermal heating beneath the West Antarctic Ice Sheet, contributing to melting of basal ice and potentially supporting microbial life. The measurement could help explain the ice sheet's rapid melting and destabilization, essential for predicting future behavior.
Researchers at the University at Buffalo School of Public Health and Health Professions will examine diver physiology during and after underwater activities. The study aims to develop Navy diving protocols to prolong endurance and make missions safer for divers.
Researchers investigated daily fluctuations in human buccal mucosa cells over a year, revealing significant daily rhythms in eleven fatty acids. The study suggests that the cellular changes may be linked to environmental conditions and could have implications for human health.
Researchers have confirmed plutonium's magnetism using neutron scattering, resolving a scientific mystery that had gone unsolved for seven decades. The discovery provides insight into plutonium's unique electronic properties and suggests new avenues for materials science applications.
Researchers at the University of Warwick have discovered a new cell structure called the mesh, which helps hold together cells and is partly made of protein TACC3 found to change in certain cancers. The finding provides crucial insight into why cancer cells develop incorrectly during division.
A post-tropical depression has formed in the Central Pacific Ocean, located northeast of Hawaii. Swells from the system are expected to cause high surf along east-facing shores of the main Hawaiian Islands over the next several days.
A 30-year study found Northern China's soil moisture decreased by 6% since 1983, with optimal levels now below 40%. The researchers attribute this decline to increased fertilizer use and crop types with high water demands, posing a risk to agriculture and the fresh water supply.
Researchers at EMBL Heidelberg have produced detailed images of the COPI coat surrounding vesicles that transport molecules within cells. The intricate protein structure is composed of repeating building blocks called triads, which organize functional elements in a precise 3D structure.
Research presented at AOSSM Annual Meeting shows surgery to be an effective treatment option for multidirectional shoulder instability. A study of 41 athletes who received arthroscopic surgery found 73% returned to play with equal or slightly lower performance.
Researchers developed a graphene-based film that efficiently cools electronics by increasing thermal conductivity to four times that of copper. The film can be attached to silicon components, overcoming previous adhesion issues, and has been tested with an additive creating stronger silane bonds, resulting in improved heat transfer.
A multicenter observational study found that collegiate collision athletes treated with arthroscopic stabilization had a successful return to play rate of 90% compared to nonoperative treatment at 35%. Athletes with subluxation or dislocation types were more likely to return to play without recurrent instability issues.
Researchers at USC's Stem Cell labs have discovered new genes affecting blood stem cell development and function. The study found that certain genetic regulators, such as Hopx, play a crucial role in the formation of red and white blood cells in adults.
Researchers developed a diagnostic test for sperm RNA based on next-generation sequencing, which may help determine the best infertility treatment for couples having difficulty conceiving. The test can identify those who benefit from assisted reproductive technologies and those who may be successful with minimal intervention.
