A new study of the impact on marine life of seismic air guns, used in geological surveys of the seafloor, has found that the sensory organs and righting reflexes of rock lobster can be damaged by exposure to air gun signals.
Published in the journal Proceedings of the Royal Society B, the research by scientists from IMAS and the Centre for Marine Science and Technology at Curtin University is the latest in a series of studies they have conducted into how seismic surveys affect marine animals.
CHICAGO--July 25, 2019--High empathy scores could become part of the criteria for getting into medical school, according to research published in The Journal of the American Osteopathic Association.
The study gauged empathy levels of 16,149 new matriculants and first- through fourth-year medical students, establishing a set of national norms, which serve as a bench mark for assessing future applicants' suitability to the profession.
WASHINGTON -- After learning that a warning of a missile headed to Hawaii was a false alarm, the most anxious local Twitter users calmed down more quickly than less anxious users, according to a study of tweets before, during and after the event, published by the American Psychological Association.
An international collaboration led by scientists mainly at Tokyo University of Agriculture and Technology (TUAT) , Japan, has found that bone and muscle mass are regulated by the altered gravity. The experiments were done in space using Kibo, a ISS module developed by JAXA, and on the ground.
The researchers published their results on April 29th in the journal, Scientific Reports.
Research by Drexel University and the University of Colorado at Boulder suggests that imposing fees on energy producers that emit greenhouse gas could improve the health and financial well-being of the Rocky Mountain region.
Two hundred and sixty-one years ago, Linnaeus formalized binomial nomenclature and the modern system of naming organisms. Since the time of his first publication, taxonomists have managed to describe 1.8 million of the estimated 8 to 25 million extant species of multicellular life, somewhere between 7% and 22%. At this rate, the task of treating all species would be accomplished sometime before the year 4,000.
When cells change to a more specialized type, we call this process cellular differentiation. Scientists have revealed that protein secretions by skin cells known as keratinocytes control the differentiation of subsurface skin fat cells. This discovery could potentially help to treat obesity. Associate Professor Takehiko Ueyama and Professor Naoaki Saito at the Biosignal Research Center of Kobe University led the research team, and the findings were published on July 24 in the online edition of the Journal of Investigative Dermatology.
An international team of scientists have observed a previously unclear inflammatory mechanism caused by airborne particles that can worsen asthma symptoms, it has been reported in Toxicological Sciences.
Researchers from the University of Notre Dame and Emory University published a new paper in the Journal of Marketing that examines whether price-based recovery incentives after service failures retain customers in the long run.
The study, forthcoming in the September issue of the Journal of Marketing and titled "The Unintended Consequence of Price-based Service Recovery Incentives," is authored by Vamsi K. Kanuri and Michelle Andrews.
Nearly three years later, it's rare to read a postmortem of the 2016 presidential election that doesn't include at least a passing mention of one of the electorate's more elusive unicorns: the Obama-to-Trump voter.
Ribosomes, the essential machinery used for protein synthesis is recycled after each one round of translation. An enzyme called ABCE1 is responsible for this process and turns out to be remarkably plastic as Ludwig-Maximilians-Universitaet (LMU) in Munich biophysicists report.
Cichlids (Cichlidae) are a group of small to medium-sized fish that are ubiquitous in
freshwater habitats in the tropics. They are particularly notable in exhibiting a wide range of
morphological and behavioral specializations, such as various modes of parental care,
including mouthbrooding. Some species (mainly members of the genus Tilapia) have
achieved fame as culinary delicacies and are of considerable economic significance. Cichlids
have undergone rapid diversification in Africa, which is home to at least 1100 species. This
Immune cells prevent bacteria, parasites or viruses from entering the body when, for example, the intestinal epithelium is injured. They respond with restricted inflammatory reactions, which are controlled via various processes in the healthy organism. If an organism suffers from Crohn's disease, for example, the immune cells are continuously activated. The research group led by Professor Thomas Brunner at the University of Konstanz has demonstrated that the transcription factor LRH-1 plays a key role in immune cells.
Preclinical trials were held on mice. Senior Research Associate Alexander Deneka (Laboratory of Molecular and Biochemical Bases of Pathogenesis and Therapy of Cancer Diseases, Kazan Federal University) explains that the method in question was first proposed by British scientists; they proved that liquid can be drained from a pleural cavity with the help of a talcum powder solution.
