Expanding the genetic code with quadruplet codons

One of modern biologists' most ambitious goals is to learn how to expand or otherwise modify the genetic code of life on Earth, in order to make new, artificial life forms. Part of the motivation for this "synthetic biology" research is to understand more about the evolution and the logic of the natural biology we've inherited. But there's also a very practical motivation: Cells can be used as efficient factories for making a broad array of useful molecules—especially protein-based therapeutics, which account for an increasing share of new medicines. Cells working with an expanded genetic code could make a much more diverse set of such medicines and could do so in a way that greatly simplifies the overall process of developing and manufacturing them.

Seismic study reveals key reason why Patagonia is rising as glaciers melt

The icefields that stretch for hundreds of miles atop the Andes mountain range in Chile and Argentina are melting at some of the fastest rates on the planet. The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia. from Phys.org - latest science and technology news stories https://ift.tt/j1h2ds5

New method to detect and visualize sperm cells recovered from forensic evidence

One of the most valuable forms of forensic evidence in cases of male-perpetrated sexual assault is the presence of semen, either in the form of stains left behind on items or on swabs collected from victims after an offense. To confirm that semen is present, suspected stains are examined under a microscope to see if any sperm cells are visible. from Phys.org - latest science and technology news stories https://ift.tt/2XBwacB
