The southwest Indian Ocean cyclone season started on November 15, 2017 and will officially end on April 30, 2018. A tropical cyclone called Fakir formed on April 23 near northeastern Madagascar and the Global Precipitation Measurement mission or GPM core satellite looked at the storm's rainfall rates.
The rise of social media and fake news challenge long-held assumptions about the First Amendment and are undermining the functioning of the 'the marketplace of ideas,' a Duke professor argues in a new article. Much of our thinking about the First Amendment assumes that the answer to false speech is more speech, or counter-speech, and that the truth will triumph in the marketplace of ideas, he says. That may be changing.
Researchers tracked genomic alterations detected in patient samples during tumor cell evolution in culture, in patient-derived xenograft (PDX) mouse models from the cultures, as well as before and after treatment in patients. In a recent paper in Nature Genetics, the team reports that tumor progression was often driven by cancer-promoting genes, known as oncogenes, on extrachromosomal pieces of DNA.
From energy materials to disease diagnostics, new microscopy techniques can provide more nuanced insight. Researchers first need to understand the effects of radiation on samples, which is possible with a new device developed for holding tightly sealed liquid cell samples for transmission electron microscopy.
Walls are what they are -- big, dull dividers. With a few applications of conductive paint and some electronics, however, walls can become smart infrastructure that sense human touch, and detect things like gestures and when appliances are used. Researchers at Carnegie Mellon University and Disney Research found that they could transform dumb walls into smart walls at relatively low cost using simple tools and techniques, such as a paint roller.
Using new technologies to track how vision guides foot placement, researchers at the University of Texas at Austin come one step closer in determining what is going on in the brain while we walk, paving the way for better treatment for mobility impairments -- strokes, aging and Parkinson's -- and technology development -- prosthetics and robots.
Researchers from the University of Texas at Dallas developed a way to extract more power from the wind. The researchers used supercomputers at the Texas Advanced Computing Center to filter out the effects of turbulence and apply control algorithms that can better manage the operation of wind farms. The approach has the potential to increase wind power generation by 6-7 percent with a estimated increase in revenue of more than $600 million nationwide.
Nature has inspired a coating for synthetic leather that repels oil and water -- and keeps the material from getting sticky in the heat.
A team led by Columbia University Biomedical Engineering Professor Gordana Vunjak-Novakovic has designed a creative new approach to help injured hearts regenerate by applying extracellular vesicles secreted by cardiomyocytes rather than implanting the cells. The study shows that the cardiomyocytes derived from human pluripotent stem cells (derived in turn from a small sample of blood) could be a powerful, untapped source of therapeutic microvesicles that could lead to safe and effective treatments of damaged hearts.
In a new study published April 23 in the journal Nature Physics, Yale researchers 'pitch' a qubit -- a tiny bit of quantum data -- from one physical point in a microwave cavity to a separate point in a different cavity. It is the first time an end-to-end quantum transmission has been done on demand and represents the first of two Yale experiments involving 'pitch-and-catch' technologies that will be published this year.
