A new study points to yet another human factor that is hampering the ability of fish to reproduce: the timing of our fishing seasons. The study considers how the timing of fishing efforts might disproportionately target certain fish and change the life history patterns of entire populations.
Researchers in physics and mathematics have long used 'preprints' -- preliminary versions of their scientific findings published on internet servers for anyone to read. In 2013, similar services were launched for biology, but following a chance discovery, a scientist and historian has unearthed a long-forgotten experiment in biology preprints that took place in the 1960s.
Scientists working in the vanguard of new genetic technologies have issued a cautionary call to ensure that possible applications in conservation will only affect local populations. Experts have now examined the possible consequences of the accidental spread of existing self-propagating gene drive systems.
European forest managers can have their cake and eat it, because according to a new study maximizing timber production in a forest does not necessarily have to come at a cost of reduced species diversity or the capacity to regulate climate change by the same forest. However most European forests fall well below their possible maximum levels of these three capacities.
Opioid pain relievers can be extremely effective in relieving pain, but can carry a high risk of addiction and ultimately overdose when breathing is suppressed and stops. Scientists have discovered a way to separate these two effects -- pain relief and breathing -- opening a window of opportunity to make effective pain medications without the risk of respiratory failure.
Birth defects in babies born infected with Zika virus remain a major health concern. Now, scientists suggest the possibility that some women in high-risk Zika regions may already be protected and not know it. New research performed in mice, shows women who develop symptom-free Zika infections may be able to acquire immunity that would protect them from future infections and their offspring in a future pregnancy.
Two recent studies show how solar flares exhibit pulses or oscillations in the amount of energy being sent out. Such research provides new insights on the origins of these massive solar flares and the space weather they produce. This is key information as humans and robotic missions venture out into the solar system, farther and farther from Earth.
While simulation platforms have been used to train surgeons before they enter an actual operating room (OR), few studies have evaluated how well trainees transfer those skills from the simulator to the OR. Now, a study that used noninvasive brain imaging to evaluate brain activity has found that simulator-trained medical students successfully transferred those skills to operating on cadavers and were faster than peers who had no simulator training.
The first study of how personal traits affect driver distraction finds that young men, extroverted or neurotic people, and people who drive more often are more likely to report being distracted during driving, while older women and those who feel they could control their distracted behavior are less likely to report distraction. The study also proposes future directions for interventions to reduce distracted driving.
