Submission + - Australian Scientists Just Worked Out How Zinc-Air Batteries Can Replace Lithium (gizmodo.com.au)

labnet writes: "Up until now, rechargeable zinc-air batteries have been made with expensive precious metal catalysts, such as platinum and iridium oxide. In contrast, our method produces a family of new high-performance and low-cost catalysts."

These new catalysts are produced through the simultaneous control of the composition, size and crystallinity of metal oxides of earth-abundant elements like iron, cobalt and nickel. They can then be applied to build rechargeable zinc-air batteries.

Researcher Dr Li Wei, also from the University's Faculty of Engineering and Information Technologies, said trials of zinc-air batteries developed with the new catalysts had demonstrated "excellent rechargeability" – including less than a 10 percent battery efficacy drop over 60 discharging/charging cycles of 120 hours.

Submission + - Hacker Helps Family Recover Minivan After Losing One-Of-A-Kind Car Key (bleepingcomputer.com)

An anonymous reader writes: A hacker and a mechanic have helped a family regain access to their hybrid car after they've lost their one-of-a-kind car key while on vacation. The car in question is a Toyota Estima minivan, which a Canadian family bought reused and imported from Japan. When they did so, they received only one key, which the father says he lost when he bent down to tie his son's shoelaces.

Because it was a hybrid and the on-board computer was synced to the battery recharge cycles, the car owner couldn't simply replace the car key without risking the car battery to overcharge and catch fire. After offering a reward, going viral on Facebook, in Canadian media, and attempting to find the lost keys using crows, the family finally accepted the help of a local hacker who stripped the car apart and reprogrammed the car immobilizer with new car keys. The whole ordeal cost the family two months of their lives and around $3,500.

Submission + - Scientists Finally Unlock the Recipe For Magic Mushrooms (gizmodo.com)

An anonymous reader writes: Aside from being a schedule 1 drug, scientists haven't fully understood the chemistry behind how mushrooms produce the chemical psilocybin — until now. A new study may finally lay the groundwork for a medical-grade psilocybin patients can take. Gizmodo reports: "Living things make molecules through a series of chemical reactions, similar to how car makers produce cars on assembly lines. Enzymes act as the workers/robots, speeding up the reactions by helping put the pieces together. Actually making psilocybin requires mapping the biological factory. A 1968 paper (obviously it was in 1968) offered a proposed order of events leading to a finished psilocybin molecule, by adding radioactive elements and watching what happened to them on the assembly line. The researchers thought that maybe tryptophan, the amino acid everyone wrongly says makes you sleepy, was the first piece, which then went through four successive steps to become the finished product. The new study shows that the 1968 paper got the order wrong, and introduces the responsible genes and enzymes, the workers that do the specific task to get the final product. This time around, mapping the factory required sequencing the genomes of two magic mushroom species, Psilocybe cubensis and Psilocybe cyanescens. Then, the researchers found exactly which genes produce the required enzymes and spliced them into E. coli bacteria. Using those enzymes, they were able to rebuild the factory and create their own psilocybin."

Submission + - Whoop! Guam radio stations conduct unscheduled emergency alert (facebook.com) 1

the_webmaestro writes: A couple of radio stations in Guam conducted an unscheduled test of the Emergency Alert Broadcast System, sending some residents--already on edge due to the back & forth between the North Korean Regime and the tweets made by the President of the United States--into a panic.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD), in conjunction with the Mariana Regional Fusion Center (MRFC), our federal and military partners, continue to monitor the recent events surrounding North Korea and their threatening actions.
[..]
Residents and visitors may have noticed at 12:25 a.m., an unscheduled test of the Emergency Alert Broadcast System (EAS) was triggered from KTWG/KSTO AM. The message read:
A BROADCAST STATION OR CABLE SYSTEM HAS ISSUED A CIVIL DANGER WARNING FOR THE FOLLOWING COUNTIES/AREAS:

Guam, Guam;
AT 12:25 AM
ON AUG 15, 2017
EFFECTIVE UNTIL 12:40 AM.
MESSAGE FROM KTWGKSTO.

The unauthorized test was NOT connected to any emergency, threat or warning. GHS/OCD has worked with KSTO to ensure the human error will not occur again. There is no scheduled test of the EAS or All Hazards Alert Warning System sirens today.

In addition, the Guam Power Authority (GPA) reported there were two scheduled outages, for emergency interruption of power, at 2:30 p.m. and 7 p.m., August 14...

Unrelated to the EAS unauthorized test, the Guam Power Authority (GPA) reported there were two scheduled outages, for emergency interruption of power, at 2:30 p.m. and 7 p.m., August 14 for customers located in Talofofo located along along Rte.17, Chalan J. Kindo, Vicente Borja Dr., Felix Dydasco St., Henry Simpson area to bus shelter by Bishop Street and other customers in these locations.
