A new model is providing insight into the impact of invasive lionfish on coral reefs in the Atlantic Ocean and Caribbean Sea. The venomous predatory fish has invaded more than 7.3 million square kilometres in the Atlantic and Caribbean, wreaking havoc among native fish populations.
The method, developed and tested with coral reef fish in the Bahamas through an international collaboration of scientists in Canada, the United States, and United Kingdom, is based on the behaviours used by prey to avoid being eaten by predators that use different hunting tactics.
CLEMSON, South Carolina - A faculty-led team of graduate and undergraduate researchers from Clemson University's Eukaryotic Pathogens Innovation Center (EPIC) has unveiled new findings that may help pave the way to an eventual cure for a parasitic infection that affects millions around the nation and world.
A new study has found that specialist active management firms outperform those that have a more mixed offering of active and passive products, with the benefit of specialisation being 0.7 per cent a year on average.
It is the first study to explore the impact of specialisation and is published this month in the journal International Review of Financial Analysis.
Researchers have conclusively shown that people with autistic traits show less empathy and reduced understanding of other people's feelings in a new study out today from the University of Bath and King's College London (1000 BST Friday 7 June 2019).
Whilst autism might be associated with social difficulties, there has been debate in recent years about whether the autistic community experience difficulties in processing emotion or not and the exact form this takes.
New research examining the impact of outsourcing NHS hip operations to the private sector concludes that continuing the trend towards private provision and reducing NHS provision is likely to result in risk selection and widening inequalities in the provision of elective hip operations in England.
Researchers from the University of Southern California, University of Houston, and Uber Technologies, Inc. published a new paper in the Journal of Marketing, which finds that in order to create viral ads, brands should arouse strong emotion, place brand mentions at the end of the video, keep ads to a moderate length of 1.0 to 1.5 minutes, and use authentic characters. To arouse emotions, a brand should create an ad with a captivating plot, a surprising ending, and authentic characters; they also should use babies and animals more than celebrities.
Commercial fishers are acutely aware of the potential for marine litter to cause lasting damage to their catches and the wider industry, a new study suggests.
They also appreciate they can be part of the solution, but believe others - including the shipping and offshore industries - could be doing more to support their efforts to prevent items of marine litter ending up in our oceans.
A new study from researchers at the University of Illinois at Chicago finds that only one-third of pharmacies in Philadelphia carry naloxone nasal spray, a medication used to rapidly counter the effects of opioid overdose, and that many of the pharmacies that do carry the drug require patients to have a physician's prescription for it.
Bottom Line: Examining to what extent firearm ownership and accessibility may be associated with suicide risk among U.S Army soldiers was the aim of this psychological autopsy study. The study included 135 soldiers who died by suicide on active duty between 2011-2013; firearms were the most common method with 61 of 111 soldiers who had a documented method of injury dying this way. Other soldiers were included for comparison based on sociodemographic and Army history risk factors for suicide death, as well as soldiers with recent suicidal thoughts.
Bottom Line: Pennsylvania became one of the first states in 2015 to implement a statewide standing order allowing pharmacists to dispense naloxone, an antidote for opioid overdoses, without a physician's prescription. This study looked at the availability (with or without a prescription) of naloxone nasal spray at 418 pharmacies in Philadelphia surveyed by telephone. The authors report 1 in 3 pharmacies had naloxone nasal spray in stock but many still required a physician's prescription.
Boston, MA - Total costs of care are similar or somewhat lower among teaching hospitals compared to non-teaching hospitals among Medicare beneficiaries treated for common medical and surgical conditions, according to a new study led by researchers from Harvard T.H. Chan School of Public Health and Beth Israel Deaconess Medical Center.
SAN ANTONIO - Preliminary findings from a new study of middle school and high school students suggest that they got more sleep and were less likely to feel too sleepy to do homework after their district changed to later school start times.
How do we choose our food? By studying the neurobiological mechanisms involved in food choices of rodents, neuroscientists at the University of Geneva (UNIGE), Switzerland, have identified the important and lasting influence that peers can have on eating habits. Indeed, sensory stimuli linked to social contacts profoundly modify the neural connections of the networks involved in food choice, highlighting the social transmission of a food preference.
The supermassive black holes in the centres of many galaxies seem to have a basic influence on their evolution. This happens during a phase in which the black hole is consuming the material of the galaxy in which it resides at a very high rate, growing in mass as it does so. During this phase we say that the galaxy has an active nucleus (AGN, for active galactic nucleus).
A team of researchers from Germany and Russia, including Vadim Nikulin from the Higher School of Economics, have demonstrated that long contraction of muscles in one hand increases involuntary reaction of the other one. Meanwhile, the time between muscle contractions in both hands decreases. The results of the study have been published in Neuroscience.
