+ - Z machine makes progress toward nuclear fusion->

Submitted by sciencehabit
sciencehabit (1205606) writes "Scientists are reporting a significant advance in the quest to develop an alternative approach to nuclear fusion. Researchers at Sandia National Laboratories in Albuquerque, New Mexico, using the lab’s Z machine, a colossal electric pulse generator capable of producing currents of tens of millions of amperes, say they have detected significant numbers of neutrons—byproducts of fusion reactions—coming from the experiment. This, they say, demonstrates the viability of their approach and marks progress toward the ultimate goal of producing more energy than the fusion device takes in."

+ - NASA: Dead star 10 million times brighter than sun->

Submitted by mpicpp
mpicpp (3454017) writes "Astronomers have found the brightest pulsar ever recorded, the 'Mighty Mouse' of stars.

NASA announced this week that its astronomers have discovered the brightest pulsar ever recorded.

The star, captured by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, is located in the center of the Messier 82 galaxy, which is about 12 million light-years from the milky way.

Because of its brightness and size, the star has some interesting characteristics. "It has all the power of a black hole, but with much less mass," Fiona Harrison, the NuSTAR principal investigator at the California Institute of Technology in Pasadena, California, said in a press release."

1: A lot of ranch vehicles tend to go a long distance, but get parked near the same spot at night, so an electric charger is useful.

2: Trucks need torque at 0RPM. Electric motors deliver here in spades.

3: Welders and other tools are needed. Having a heavy duty inverter and the ability to use the battery bank for powering an air compressor would come quite handy.

4: Electric motors need a lot less upkeep than a diesel engine. No pee cans, no DPFs, no EGR valves, air filters, oil filters, just very minimal maintenance required.

5: They use no fuel when stopped/idling, other than to keep the vehicle electronics going and the climate control system.

6: They are quiet.

7: An electric motor can sit indefinitely without worry about fuel turning to sludge (in the case of gasoline) or getting algae in it (like diesel.)

8: No exhaust.

9: Wet dreams about the size of spotlight you can put on it

+ - Decline of bees and other pollinators could worsen global malnutrition->

Submitted by sciencehabit
sciencehabit (1205606) writes "Although bees, butterflies, and other winged creatures serve as natural pollinators for many of the world’s plants, they contribute only modestly to the world’s agricultural production—accounting for between 5% and 10% of the production of food crops. However, such natural pollinators may play a disproportionately large role in human nutrition and health, according to a new study. That's because pollinators support crops that deliver essential nutrients to malnourished regions of the world, the data show, suggesting that regions already facing food shortages and nutritional deficiencies may be especially hard hit by the global decline of bees and other pollinators."

+ - Schmidt Says Attack on Google Prompted Encryption Changes

Submitted by Trailrunner7
Trailrunner7 (1100399) writes "Eric Schmidt, executive chairman of Google, said that the changes to Android's encryption model, which have angered law enforcement officials, should have come as no surprise to law enforcement and government agencies, given the events of the last couple of years.

“The people who are criticizing this should’ve expected this. After Google was attacked by the British version of the NSA we were annoyed to no end,” Schmidt said. “We put in encryption end to end, at rest and in transit. Law enforcement has many many ways to get this information without doing this.”

After the details of Apple’s and Google’s encryption changes became public, some in the law enforcement community have suggested that the companies should include a backdoor in their devices. Both Sen. Ron Wyden and Schmidt dismissed this suggestion out of hand.

“U.S. companies shouldn’t be forced to build backdoors into their products,” Wyden said."

+ - NASA asks Boeing, SpaceX to stop work on next-gen space taxi

Submitted by BarbaraHudson
BarbaraHudson (3785311) writes "Due to a challenge by Sierra Nevada, NASA has asked the winners for the next earth-to-orbit launch vehicles to halt work, at least temporarily.

After rewarding Boeing and SpaceX with the contracts to build the spacecrafts NASA is now asking the companies to stop their work on the project.

The move comes after aerospace company Sierra Nevada filed a protest of the decision after losing out on the bid.

Sierra Nevada was competing against Boeing and SpaceX for a share of the $6.8 billion CCP contracts. The contracts will cover all phases of development as well as testing and operational flights. Each contract will cover a minimum of two flights and a maximum of four, with each agency required to have one test flight with a NASA representative on board.

On Sept. 16, NASA announced who the winners were of the Commercial Crew Transportation Capability (CCtCAP) contracts. Sierra Nevada then filed a protest with the GAO on Sept. 26, and issued a statement saying the protest was asking for: “a further detailed review and evaluation of the submitted proposals and capabilities.”

According to NASA’s Public Affairs Office, this legal protest stops all work currently being done under these contracts. However, officials have not commented on whether-or-not the companies can continue working if they are using private funds.

Sierra Nevada's orbiter resembles a mini space shuttle. That alone (remember the problems with the tiles) should have been enough to disqualify them."

+ - HP Is Planning To Split Into Two Separate Businesses

Submitted by mrspoonsi
mrspoonsi (2955715) writes "Hewlett-Packard is planning to split itself into two separate businesses, The Wall Street Journal is reporting. Sources tell the WSJ that HP will split its personal-computer and printer segments from its corporate hardware and services business. The announcement could come as early as Monday, the sources said. The company reorganized itself in 2012 under CEO Meg Whitman. That move combined its computer and printer businesses. The PC and computer segment is massive for HP. For the first six months this year, it reported $27.8 billion in revenue. That's about three times the size of HP's next biggest unit, the Enterprise Group, which makes servers, storage, and network hardware. Under the new split, Whitman would be chairman of the computer and printer business, and CEO of a separate Enterprise Group, according to one of the sources. Patricia Russo, who sits on HP's board, would be chairman of the enterprise company. The printer and PC operation would be led by Dion Weisler, a current exec in that division."
