Nanofiber gel and snake venom work together to stop the bleeding

Researchers at Rice University announced a novel use for batroxobin , a hemotoxic component in the venom of two South American pit viper species. They’ve figured out how to leverage it as a potent anticoagulant — when combined with a nanofiber hydrogel called SB50 — that could save countless lives in surgery. Medical science has actually been employing batroxobin as a topical clotting agent and thrombosis treatment since the mid 1930s. But more importantly, it’s been shown to stop the flow of blood even if the patient is on heparin, a powerful anticoagulant administered before some surgeries.

Patricia, Strongest Hurricane Ever Seen In Eastern Pacific, Strikes In Mexico

CNN reports that Hurricane Patricia has made landfall in Mexico; Patricia is notable for having the third-lowest barometer reading ever recorded, and as “the strongest hurricane ever observed in the eastern Pacific or Atlantic oceans.” Slate points out that at one point, “satellite estimates of Patricia’s intensity broke the Dvorak scale, peaking at 8.3 on the 8.0 scale. … In fact, Patricia is now very close to the theoretical maximum strength for a tropical cyclone on planet Earth.” The Weather Channel is tracking the storm’s path, and predicts “catastrophic damage … along a narrow path as the eye slices into the interior of southwest Mexico Friday night.” Here’s a map from the National Weather Service showing Patricia’s track as well as projected path.

Short story vending machine promises old-school distractions

In the French city of Grenoble, there are unusual vending machines that don’t dispense soda or snacks — they print out short stories that look like paper receipts instead. These machines were built by a publishing company called Short Édition , which placed eight of them in public locations (such as the city hall and libraries) as part of a pilot project. Each dispenser has 1-minute, 3-minute and 5-minute buttons, so readers can choose how long their stories are, all of which were written by members of the Short Édition community. Company co-founder Christophe Sibieude told Agence-France Presse that his team came up with the idea while in front of a chocolate candy machine: “We said to ourselves that we could do the same thing with good quality popular literature to occupy these little unproductive moments.” Best thing about these story dispensers is that they’re free, giving residents something to do if ever they get tired of poking on their phones or want to read the old school way.

Mimic, the Evil Script That Will Drive Programmers To Insanity

JustAnotherOldGuy writes: Mimic implements a devilishly sick idea floated on Twitter by Peter Ritchie: “Replace a semicolon (;) with a Greek question mark (;) in your friend’s C# code and watch them pull their hair out over the syntax error.” There are quite a few characters in the Unicode character set that look, to some extent or another, like others – homoglyphs. Mimic substitutes common ASCII characters for obscure homoglyphs. Caution: using this script may get you fired and/or beaten to a pulp. Read more of this story at Slashdot.

Ubuntu 15.10 ‘Wily Werewolf’ Released

LichtSpektren writes: Ubuntu 15.10 “Wily Werewolf” is now released and available, along with its alternative desktop flavors (MATE, Xfce, LXDE, GNOME, KDE, Kylin). This release features Linux 4.2, GCC 5, Python 3.5, and LibreOffice 5. The default version is still using X.org display server and Unity7; Mark Shuttleworth has said that Mir and Unity8 won’t arrive until Ubuntu 16.04 “Xenial Xerus.” Not much has changed beyond package updates, other than replacing the invisible overlay scrollbars in Nautilus with the GNOME 3 scrollbars. Phoronix brings us the only bit of drama regarding this release: Jonathan Riddell, long time overseer of Kubuntu, has resigned with claims that Canonical has “defrauded donors and broke the copyright licenses.” Another reader adds a link to a Q & A session with Riddell.

Harvard creates a material that lets light go ‘infinitely fast’

Researchers at Harvard University announced recently that they had successfully developed a means of manipulating light at the nanoscale, which could lead to photonic-based ( rather than electronic ) telecommunications. Think, ubiquitous fiber optics. The team reportedly developed an on-chip metamaterial made from silicon pillars embedded in polymer and wrapped in gold film that exhibits a refractive index of zero. In English, that means that the phase of light passing through this material can travel infinitely fast without violating the known laws of physics. Source: Harvard University

How Twitter helped make the ‘Archer’ pinball game a reality

Pinball FX creator Zen Studios released a bundle this week featuring tables from Archer , Family Guy , Bob’s Burgers and American Dad . The pack, called Balls of Glory , is available now across PS3, PS4, Vita, Xbox 360, Xbox One, Windows 10, Steam, Android and iOS ( whew ). And all of this exists because of a tweet, as Zen Studios VP of Publishing Mel Kirk explains.

3D-Printed Teeth Can Kill 99% of Dental Bacteria

An anonymous reader writes: A research group in the Netherlands has developed a new plastic resin that can destroy most dental bacteria when used for the creation of dental appliances via 3D-printing. The process involves embedding antimicrobial quaternary ammonium salts inside extant dental resin polymers. Since the salts are positively charged, these disrupt negatively-charged bacterial membranes. The process is also being mooted for use in the creation of knee arthroplasties, and in the manufacture of children’s toys and food packaging. Read more of this story at Slashdot.

Scientists stretch metal to make it stronger

You’d think that stretching metal would make it weaker, but just the opposite is true… on a very small scale. Researchers have developed a technique that pulls nanoscopic metal crystals to eliminate defects. By gently and repeatedly stretching the crystal, scientists move “dislocations” (rows of atom-level defects) to free surfaces, where they’re ultimately forced out. The result is a metal that is considerably less likely to crack or otherwise fail over time. You may not see this technique used to improve larger (that is, visible) metal, like what you see in buildings or vehicles. The same trick that improves nanoscale metal tends to make things worse at the macro level. However, it could be very helpful for processors and any other device where even the tiniest breaks could cause big problems. Don’t be surprised if you’re one day using electronics that last for years longer than you’re used to. Source: Carnegie Mellon University , PNAS

New Homeland Security policy demands warrants before deploying StingRays

The Department of Homeland Security announced a substantial policy change Wednesday regarding how it employs cellphone-tracking tools like the StingRay system. These cell-site simulators have been in use for more than a decade. They allow law enforcement to find cell phones either by directly searching for a known device or find an unknown device by sniffing for signaling information from the simulator’s immediate vicinity and triangulating that data. The new policy explicitly demands that DHS personnelle acquire a warrant before deploying the devices unless an exception, such as the imminent loss of human life, destruction of evidence, or to prevent the escape of a fugitive felon. Wednesday’s announcement follows a similar decision by the Department of Justice last month. [Image Credit: Getty] Via: Verge Source: Department of Homeland Security
