[ad_1] Synthetic biologists at Rice University have hacked bacterial detection with a plug-and-play system that can be used to mix and match tens of thousands of sensory inputs and genetic outputs. Technology has many implications for medical diagnosis, the study of deadly pathogens, environmental monitoring, and so on. In a nearly six-year project, Rice bioengineer, … Read more
[ad_1] MISSION MOON: Nearly 50 years have passed since Neil Armstrong and Buzz Aldrin became the first humans to walk on the moon. Our special coverage for Apollo 50 Anniversary explores how the country came together to achieve President John F. Kennedy's goal of reaching the lunar surface by 1970, NASA's bold missions – and … Read more
[ad_1] Left: Images of a highly metastatic (up) PC3 prostate cancer cell and bleeding, as well as a normal non-brewing RWPE-1 prostate cell, forced into a canal microfluidics. In the middle: the contours of the images on the left highlight the mixing and deformation of the cells. Right: Percentage of highly metastatic PC3 cells, moderately … Read more
[ad_1] Most climate change plans consist of reducing carbon dioxide emissions, usually by reducing human emissions. But a new unconventional idea could actually slow the progress of global warming by putting more carbon dioxide in the atmosphere – while eliminating a more powerful gas that warms the planet. In a commentary published Monday in the … Read more
[ad_1] This image illustrates the magnetic fields of Jupiter at a given moment. Credit: NASA / JPL-Caltech / Harvard / Moore et al. The magnetic field of Jupiter has changed since the 1970s and physicists have proved it. This is not really a surprise. The Earth's magnetic field, the only planetary field for which we … Read more
[ad_1] And this, kids, is how you collect the contents of the stomach of a tiger shark. Marcus Drymon Pics, sparrows and doves, oh my god. The remains of these earth-loving birds have all appeared in an unlikely place: the stomachs of baby tiger sharks. The DNA analysis of "Shark Barf" shows that young predators … Read more
[ad_1] Besides Ampère, Kelvin, Mol and Co., the kilogram is also defined by a natural constant. In concrete terms, this means that the original kilogram, which is the measure of all things for 130 years, has now been used in Paris. This is made possible by single crystals developed from highly enriched isotopic silicon-28 from … Read more
[ad_1] How can we pass from a single fertilized egg to an adult person with billions of cells? Our cells are dividing, of course! And this is not a small feat. Whenever a cell divides, it must duplicate our 23 pairs of chromosomes and ensure that each "daughter" cell ends with a full set of … Read more
[ad_1] The endless flow of electrical current from superconductors could offer new options for energy storage and extremely efficient transmission and power generation. But the zero electrical resistance of superconductors is reached only below a certain critical temperature and is very expensive to achieve. Physicists in Serbia believe they have found a way to manipulate … Read more
[ad_1] Credit: CC0 Public Domain A team of international scientists, including researchers from the University of St. Andrews, Syracuse University and Royal Holloway, of the University of London, has highlighted a new source of food for the young children of the planet. Life on Earth relies on the availability of critical elements such as nitrogen … Read more
