Plants know how to do a neat trick.
Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores -- called stomata -- to take in carbon dioxide and release oxygen.
CHAMPAIGN, Ill. -- The CRISPR-Cas9 system has given researchers the power to precisely edit selected genes. Now, researchers have used it to develop a technology that can target any gene in the yeast Saccharomyces cerevisiae and turn it off by deleting single letters from its DNA sequence.
Have you ever considered that working night shifts may, in the long run, have an impact on your health? A team of researchers from the McGill University affiliated Douglas Mental Health University Institute (DMHUI) has discovered that genes regulating important biological processes are incapable of adapting to new sleeping and eating patterns and that most of them stay tuned to their daytime biological clock rhythms.
Generic drug options did not reduce prices paid for the cancer therapy imatinib (Gleevec), according to a Health Affairs study released today in its May issue.
After nearly two years of generic competition the price for a month of treatment dropped by only 10 percent, according to authors from Vanderbilt University School of Medicine (VUSM) and University of North Carolina at Chapel Hill.
Abu Dhabi, May 7, 2018: An international team of scientists, led by Laurent Gizon, co-principal investigator of the Center for Space Science at NYU Abu Dhabi (NYUAD), have discovered planetary waves of vorticity on and inside the Sun similar to those that significantly influence weather on Earth.
Rossby waves are a natural phenomenon in the atmospheres and oceans of planets that form in response to the rotation of the planet. Like Earth, the Sun also rotates and should support Rossby waves, but their existence on the Sun has been debated, until now.
HOUSTON - (May 7, 2018) - Consumers who reflected on their recently used personal belongings experienced less desire for an unexpectedly encountered product, were less likely to buy impulsively and expressed a lower willingness to pay for new products, according to a new paper by marketing and consumer behavior experts at Rice University.
LEXINGTON, Ky. (May 4, 2018) - New findings from the University of Kentucky published in the Journal of Neuroscience demonstrate that there may be ways to address blood-brain barrier dysfunction in epilepsy.
CHAPEL HILL - Parenting concerns contributed significantly to the psychological distress of mothers with late-stage cancer, according to a study by University of North Carolina Lineberger Comprehensive Cancer Center researchers.
According to the WHO, around 700,000 people die every year as a result of antibiotic resistance. In Germany, around 6,000 people die every year because treatment with antibiotics is not effective. Scientists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the University of Oxford have now discovered that there is a point in the production process of the proteins at which it can be regulated by bacteria. This could be used as a starting point for the development of new antibiotics and help overcome resistance to antibiotics.
Jean-François Côté, a researcher at the Montreal Clinical Research Institute (IRCM) and professor at Université de Montréal's Faculty of Medicine, studies metastasis, the leading cause of cancer-related death. Recently, his team uncovered a protein that, once deactivated, could prevent the development of metastases in an aggressive type of cancer, HER2-positive breast cancer.
One in eight women will be diagnosed with breast cancer in her lifetime and one in 30 is expected to die from it. The findings, published in the journal Cell Reports, could improve this prognosis.
Data from almost 600 participants show that women's perceptions of male attractiveness do not vary according to their hormone levels, in contrast with some previous research. The study findings are published in Psychological Science, a journal of the Association for Psychological Science.
A new study published in Nature Communications shows that infants who are later diagnosed with autism react more strongly to sudden changes in light. This finding provides support for the view that sensory processing plays an important role in the development of the disorder.
Scientists from Germany, Denmark and the UK have built a model tool to predict what happens to marine animals when exposed to noise from the construction and operation of windfarms at sea. Using the North Sea harbor porpoise (Phocoena phocoena) population as a case study, they demonstrate how the model can be used to evaluate the impact of offshore wind farm construction noise. This type of noise is increasingly prevalent due to the high demand for green energy, and currently there are >900 offshore wind farms at various stages of development in Europe alone.
If dead cells accumulate in the body, they can contribute to inflammation and pre-dispose individuals to multiple chronic inflammatory conditions such as rheumatoid arthritis, cardiovascular diseases, Crohn's disease or lupus by uncharacterized pathways.
TORONTO, May 5, 2018 - Hospitals caring for children with serious, chronic illness are highly dependent on public payers, according to a new study. The research found that proposals to dramatically reduce federal expenditures on Medicaid and Children's Health Insurance Program (CHIP) could destabilize current specialty care referral networks serving all children, including the majority of privately-insured children in greatest need of high quality, specialized, pediatric care.
