Beginning in 2013, a mysterious disease crippled sea star populations up and down the U.S. west coast. Over a matter of months, many sea star species died in record-breaking numbers, though Pisaster ochraceus--a keystone species known as the ochre sea star--was among the hardest hit. Now, researchers at UC Santa Cruz have analyzed just how much the populations of this species have declined, but they have not yet determined what factors might be contributing to the epidemic.
Men who take the medication finasteride get a prostate cancer prevention benefit that can last 16 years - twice as long as previously recorded, according to SWOG clinical trial analysis published in the Journal of the National Cancer Institute.
For years, scientists have been inspired by nature to innovate solutions to tricky problems, even oil spills -- manmade disasters with devastating environmental and economic consequences. A new USC study takes a cue from leaf structure to fabricate material that can separate oil and water, which could lead to safer and more efficient oil spill clean-up methods.
VCU Massey Cancer Center researchers have identified two genes that are responsible for governing the replication of the Epstein-Barr virus, an infection that drives the growth of several types of cancer. The discovery could lead to the development of novel therapies for virus-associated diseases including stomach cancer and lymphomas.
The platypus is the ultimate evolutionary mashup of birds, reptiles and mammals. The iconic, egg-laying, venom producing, duck-billed platypus first had its genome sequenced in 2008, revealing its unique genetic makeup and its divergence from the rest of the mammals around 160 million years ago.
Now, a greater effort to understand its ecological and population history has been made possible by the first, whole-scale genome sequencing efforts of 57 platypuses across Eastern Australia and Tasmania.
A group of researchers in the Department of Financial Economics II (Company Economics and Marketing) of the UPV/EHU's Faculty of Economics and Business has conducted a study that seeks to identify the factors driving the pro-environmental behaviour of university students; the aim is to be able to increase the effectiveness of university and Government interventions and policies in favour of the environment.
Tsukuba, Japan - Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a cell determine what that cell can do. Among the multiple elements that are involved in the precise regulation of gene expression are enhancers, which are short region of DNA that can be bound by proteins (activators) to increase the likelihood of transcription of a particular gene.
Addressing the global teacher gap of 69 million should be the number one priority for education policymakers the world over, a new international study has warned.
The shortage of teachers is the biggest threat to the international goal of providing quality teaching to all children according to the study led by Prof Kwame Akyeampong, Professor of International Education and Development at the University of Sussex.
In a new study of one of the most common genetic causes of autism, neuroscientists at MIT's Picower Institute for Learning and Memory have identified a specific molecular mechanism that appears to undermine the ability of neurons in affected mice to properly incorporate changes driven by experience. The findings published in the Journal of Neuroscience therefore suggest that a particular gene, MVP, is likely consequential in people with 16p11.2 deletion syndrome.
