Endocannabinoids Contribute To Runner’s High

MTorrice writes: After a nice long bout of aerobic exercise, some people experience what’s known as a “runner’s high” — a feeling of euphoria coupled with reduced anxiety and a lessened ability to feel pain. For decades, scientists have associated this phenomenon with an increased level in the blood of beta-endorphins, which are opioid peptides thought to elevate mood. Now, German researchers have shown the brain’s endocannabinoid system—the same one affected by marijuana’s 9-tetrahydrocannabinol (THC)—may also play a role in producing runner’s high, at least in mice.

On-Chip Liquid Cooling Permits Smaller Devices With No Heatsinks Or Fans

An anonymous reader writes: DARPA-funded research into on-chip liquid cooling has resulted in a field-programmable gate array (FPGA) liquid-cooled device that can operate at 24 degrees Celsius, versus 60 degrees Celsius for an equivalent air-cooled device. The cooling fluid resides only nanometers from the heat it must address, and operates so efficiently as to offer potential to stack CPUs and GPUs using copper columns, as well as dispensing with heat-sinks and fan systems. With those components removed, the system can facilitate far more compact designs than are currently feasible. Read more of this story at Slashdot.

The Port of LA’s Big Tech Upgrade Worked So Well It’s Hitting Its 2023 Emissions Goals

If you live in the US, most of the imported goods in your possession have traveled through the Port of Los Angeles, one of the largest ports in the world , and now, one of the biggest environmental success stories on the planet. A new study shows that due to major upgrades started a decade ago, the port is almost 10 years ahead of its emissions goals. Read more…

This is What Radiation from a Chunk of Uranium Looks Like

Radiation tends to strike fear in the hearts of the general populace, particularly the ionizing variety produced by X-rays and radioactive elements. But most have no idea what actual radiation looks like. Now a French organization c alled CloudyLabs has found a way to let us see the process in action using a simple cloud chamber. Read more…

This Startup Wants To Plant One Billion Trees a Year Using Drones

Deforestation downs 10 billion trees around the globe annually. Replanting trees by hand is slow, expensive, and barely puts a dent in reversing the damage. But one startup wants to use drones that can reforest our increasingly tree-strapped Earth, on a big enough scale to replace slow and expensive hired humans. Read more…

DHS Detains Mayor of Stockton, CA, Forces Him To Hand Over His Passwords

schwit1 writes: Anthony Silva, the mayor of Stockton, California, recently went to China for a mayor’s conference. On his return to San Francisco airport he was detained by Homeland Security, and then had his two laptops and his mobile phone confiscated. They refused to show him any sort of warrant (of course) and then refused to let him leave until he agreed to hand over his password. Read more of this story at Slashdot.

Stagefright 2.0 Vulnerabilities Affect 1 Billion Android Devices

msm1267 writes: Security researcher Joshua Drake today disclosed two more flaws in Stagefright, one that dates back to the first version of Android, and a second dependent vulnerability that was introduced in Android 5.0. The bugs affect more than one billion Android devices, essentially all of them in circulation. One of the vulnerabilities was found in a core Android library called libutils; it has been in the Android OS since it was first released and before there were even Android mobile devices. The second vulnerability was introduced into libstagefright in Android 5.0; it calls into libutils in a vulnerable way. An attacker would use a specially crafted MP3 or MP4 file in this case to exploit the vulnerabilities. Google has released patches into the Android Open Source Project tree, but public patches are not yet available. Read more of this story at Slashdot.

ALS Patients Use a Brain Implant To Type 6 Words Per Minute

the_newsbeagle writes: With electrodes implanted in their neural tissue and a new brain-computer interface, two paralyzed people with ALS used their thoughts to control a computer cursor with unprecedented accuracy and speed. They showed off their skills by using a predictive text-entering program to type sentences, achieving a rate of 6 words per minute. While paralyzed people can type faster using other assistive technologies that are already on the market, like eye-gaze trackers and air-puff controllers, a brain implant could be the only option for paralyzed people who can’t reliably control their eyes or mouth muscles.

How to make your own bootable OS X 10.11 El Capitan USB install drive

Enlarge / Even in the download-only era, it’s easy to make yourself offline OS X install media. (credit: Andrew Cunningham) It was 2009 when Apple last released a new operating system on physical media . Things have proceeded remarkably smoothly since version 10.7 switched to download-only installers, but there are still good reasons to want an old, reliable USB stick. For instance, if you find yourself doing multiple installs, a USB drive may be faster than multiple downloads (especially if you use a USB 3.0 drive). Or maybe you need a recovery disk for older Macs that don’t support the Internet Recovery feature. Whatever the reason, you’re in luck, because it’s not hard to make one. As with last year , there are two ways to get it done. There’s the super easy way with the graphical user interface and the only slightly less easy way that requires some light Terminal use. Here’s what you need to get started. A Mac that you have administrator access to, duh. We’ve created El Capitan USB stick from both Yosemite and El Capitan, but your experience with other versions may vary. An 8GB or larger USB flash drive or an 8GB or larger partition on some other kind of external drive. For newer Macs, use a USB 3.0 drive—it makes things significantly faster. The OS X 10.11 El Capitan installer from the Mac App Store in your Applications folder. The installer will delete itself when you install the operating system, but it can be re-downloaded if necessary. If you want a GUI, you need the latest version of  Diskmaker X  app. As of this writing, version 5 is the one you’ll want for official El Capitan support, and it has been promised but not yet delivered. We’ll show you how to do it with version 4 and update the article when the update is released. Diskmaker X is free to download, but  the creator accepts donations  if you want to support his efforts.
