After decades of public safety campaigns focused on drinking and driving, it may be time to focus on the seventh leading cause of injury-related death, according to Bureau of Occupational Health and Injury Prevention at New York State Department of Health and Columbia University scholars looking at New York State.
How does a mother transition genetic control to offspring early in development? It's part of a larger mystery regarding how embryos regulate cell division and differentiation into new types of cells.A new article in Cell provides some insight into the mechanism for this genetic hand-off, which happens within hours of fertilization, when the newly fertilized egg is a zygote.
A new paper notes that the Campanian Ignimbrite eruption in Italy 40,000 years ago, one of the largest volcanic cataclysms in Europe and responsible for injecting a significant amount of sulfur-dioxide (SO2) into the stratosphere, coincided with the final decline of Neanderthals as well as with dramatic territorial and cultural advances among modern humans. Scientists have long debated if this eruption and the resulting volcanic sulfur cooling and acid deposition could have contributed to the final extinction of the Neanderthals more than climate change or hominin competition. A new paper tests this hypothesis using a climate model.
The leading theory of what causes ice ages around the world -- changes in the way the Earth orbits the sun- has been cast into doubt by a new study.
The study raises questions about the Milankovitch theory of climate, which says the expansion and contraction of Northern Hemisphere continental ice sheets are influenced by cyclic fluctuations in solar radiation intensity due to wobbles in the Earth's orbit; those orbital fluctuations should have an opposite effect on Southern Hemisphere glaciers.
A new study finds that even a brief nap can significantly improve memory retention of learned material.Saarland University
graduate student Sara Studte, PhD supervisor Axel Mecklinger and co-researcher Emma Bridger have examined how power naps influence memory performance.
A comprehensive study examining clinical trials of more than 95,000 patients has found that glucose or sugar-lowering medications prescribed to patients with diabetes may pose an increased risk for the development of heart failure in these patients.
Patients who received the new drug Bendavia before undergoing angioplasty or receiving a stent to clear blocked arteries after a heart attack showed no significant reduction in scarring as compared to patients given a placebo, according to a study presented at the American College of Cardiology's 64th Annual Scientific Session.
The annual Rethink Media conference was held yesterday at Birmingham City University to address the future of the digital landscape and the challenges facing the sector and, predictably, there was plenty of blame to go around, and assurances that the answers were simple - but as usual when panels get together to lament the future, no one was doing anything.Schools got the brunt of the cultural shame and blame.“Schools need to fix the fact that technology is not being made aspirational for females”, urged Talk Talk’s Head of Digital, Rahul Chakkara. “Half of the talent is being lost at school level.”
Whether you're baking bread or building an organism, the key to success is consistently adding ingredients in the correct order and in the right amounts, according to a new genetic study by University of Michigan researchers.
Using the baker's yeast Saccharomyces cerevisiae, Patricia Wittkopp and her colleagues developed a novel way to disentangle the effects of random genetic mutations and natural selection on the evolution of gene expression. Their findings are scheduled for online publication in the journal Nature on March 16.
When patients develop acute liver failure, severe complications arise rapidly after the first signs of liver disease, and patients' health can deteriorate rapidly. New research published in the American Journal of Transplantation indicates that emergency evaluations of living liver donors can be conducted safely to allow acute liver failure patients to undergo transplantation before their condition worsens.
Tumors acquiring resistance is one of the major barriers to successful cancer therapy. Feng Fu, Sebastian Bonhoeffer (ETH Zurich) and their collaborator Martin Nowak (Harvard) use mathematical models to characterize how important aspects of tumor microenvironment can impair the efficacy of targeted cancer therapies.
Failure of cancer therapy is commonly attributed to pre-existing resistant mutants already present prior to treatment. However, the research publishing this week in PLOS Computational Biology highlights the important role of tumor sanctuaries in the rapid acquisition of resistance.
Scientists at Albert Einstein College of Medicine of Yeshiva University and their international collaborators have developed a novel fluorescence microscopy technique that for the first time shows where and when proteins are produced. The technique allows researchers to directly observe individual messenger RNA molecules (mRNAs) as they are translated into proteins in living cells.
The technique, carried out in living human cells and fruit flies, should help reveal how irregularities in protein synthesis contribute to developmental abnormalities and human disease processes including those involved in Alzheimer's disease and other memory-related disorders.
ESA’s Rosetta spacecraft has made the first measurement of molecular nitrogen at a comet, Comet 67P/Churyumov–Gerasimenko, providing clues about the temperature environment in which it formed.
