An anonymous reader writes: Wolf volcano in the Galapagos islands has erupted for the first time in more than 30 years, sending lava flowing down its slopes and potentially threatening the world's only colony of pink iguanas. The Galapagos National Park says that currently there is no risk to tourism operations, but the Environment Ministry is notifying tourist operators to take precautions. A tourist boat passing by took an amazing picture of the eruption.

Google's Diversity Chief: Mamas Don't Let Their Baby Girls Grow Up To Be Coders 60

from the starts-at-home dept.
theodp writes: Explaining the reasons for its less-than-diverse tech workforce, Google fingered bad parenting for its lack of women techies. From the interview with Google Director of Diversity and Inclusion Nancy Lee: "Q. What explains the drop [since 1984] in women studying computer science? A. We commissioned original research that revealed it's primarily parents' encouragement, and perception and access. Parents don't see their young girls as wanting to pursue computer science and don't steer them in that direction. There's this perception that coding and computer science is ... a 'brogrammer' culture for boys, for games, for competition. There hasn't been enough emphasis on the power computing has in achieving social impact. That's what girls are interested in. They want to do things that matter." While scant on details, the Google study's charts appear to show that, overall, fathers encourage young women to study CS more than mothers. Google feels that reeducation is necessary. "Outreach programs," advises Google, "should include a parent education component, so that parents learn how to actively encourage their daughters."

Largest Eruption In the Known Universe Is ~100 Times the Size of Milky Way 19

StartsWithABang writes: At the center of almost every galaxy is a supermassive black hole (SMBH); at the center of almost every cluster is a supermassive galaxy with some of the largest SMBHs in the Universe. And every once in a while, a galactocentric black hole will become active, emitting tremendous amounts of radiation out into the Universe as it devours matter. This radiation can cut across the spectrum, from the X-ray down to the radio. At the heart of MS 0735.6+7421, there's a >10^10 solar mass black hole that appears to have been active for hundreds of millions of years, something unheard of!

Privacy Behaviors Changed Little After Snowden 53

Posted by Soulskill
from the just-another-speed-bump-in-the-new-cycle dept.
An anonymous reader writes: An article in Communications of the ACM takes a look at how Edward Snowden's revelations about government surveillance have changed privacy behaviors across the world. The results are fairly disappointing. While the news that intelligence agencies were trawling data from everyday citizens sparked an interest in privacy, it was small, and faded quickly. Even through media coverage has continued for a long time after the initial reports, public interest dropped back to earlier levels long ago. The initial interest spike was notably less than for other major news events. Privacy-enhancing behaviors experienced a small surge, but that too failed to impart any long-term momentum. The author notes that the spike in interest "following the removal of privacy-enhancing functions in Facebook, Android, and Gmail" was stronger than the reaction to the government's privacy-eroding actions.

Its not that simple. You can't just recover it from nuclear reactor waste because it's mixed in with other isotopes of plutonium, and isn't in that great of quantities to begin with. So first off you have to reprocess nuclear waste to extract the neptunium - which again, itself isn't in very great quantities, it takes a lot of waste, and most places don't want to do waste reprocessing to begin with due to cost and liability issues. You then have to make neptunium targets and expose them to a neutron flux - that is, using neutronicity that could otherwise be used for power generation or other valuable purposes (it takes a lot of neutrons to make a tiny bit of Pu238). Pu238 should be more thought of as a manufactured product than as a byproduct of particular types of nuclear reactors.

There are a few other candidates for use as space power sources that actually are waste products, but they're all significantly worse performers. There are two other alternatives. One is to make a Sterling RTG, which was in development, but funding has been cut off (it's also kind of tricky because you have to ensure that something with moving parts will operate for decades in the harsh environment of space). The other is to make an actual nuclear reactor. This means almost limitless power, but it comes at the expense of not only massive development costs and public opposition, but a large minimum size and massive radiator requirements, as well as the same reliability challenges of sterling generators.

There's no easy solutions. Except, of course, to stop bloody wasting plutonium once we have it.

Tech Bubble? What Tech Bubble? 76

Posted by samzenpus
from the shiny-bubbles dept.
HughPickens.com writes: Conor Dougherty writes in the NYT that the tech industry's venture capitalists — the financiers who bet on companies when they are little more than an idea — are going out of their way to avoid the one word that could describe what is happening around them: Bubble. "I guess it is a scary word because in some sense no one wants it to stop," says Tomasz Tunguz. "And so if you utter it, do you pop it?" In 2000, tech stocks crashed, venture capital dried up and many young companies were vaporized. Today, people see shades of 2000 in the enormous valuations assigned to private companies like Uber, with a valuation of $41 billion, and Slack, the corporate messaging service that is about a year old and valued at $2.8 billion in its latest funding round. A few years ago private companies worth more than $1 billion were rare enough that venture capitalists called them "unicorns." Today, there are 107 unicorns and while nobody doubts that many of tech's unicorns are indeed real businesses, valuations are inflating, leading some people to worry that investment decisions are being guided by something venture capitalists call FOMO — the fear of missing out.

With interest rates at historic lows, excess capital causes investment bubbles. The result is too much money chasing too few great deals. Unfortunately, overcapitalizing startups with easy money results in superfluous spending and dangerously high burn rates and investors are happy to admit that this torrid pace of investment has started to worry them. "Do I think companies are overvalued as a whole? No," says Sam Altman, president of Y Combinator. "Do I think too much money can kill good companies? Yes. And that is an important difference."

San Bernardino Sheriff Has Used Stingray Over 300 Times With No Warrant 77

Posted by samzenpus
from the was-that-wrong? dept.
An anonymous reader writes: After a records request by Ars, the sheriff in San Bernardino County (SBSD) sent an example of a template for a "pen register and trap and trace order" application. The county attorneys claim what they sent was a warrant application template, even though it is not. The application cites no legal authority on which to base the request. "This is astonishing because it suggests the absence of legal authorization (because if there were clear legal authorization you can bet the government would be citing it)," Fred Cate, a law professor at Indiana University, told Ars. "Alternatively, it might suggest that the government just doesn't care about legal authorization. Either interpretation is profoundly troubling," he added. Further documents reveal that the agency has used a Stingray 303 times between January 1, 2014 and May 7, 2015.

Greece Is Running Out of Money, Cannot Make June IMF Repayment 577

Posted by samzenpus
from the broker-than-broke dept.
jones_supa writes: Greece, the country which has been in extreme financial trouble and high debt for years, cannot make debt repayments to the International Monetary Fund (IMF) next month, unless it achieves a deal with creditors. 'The four installments for the IMF in June are €1.6 billion ($1.8 billion). This money will not be given and is not there to be given,' Interior Minister Nikos Voutsis told Greek Mega TV's weekend show. Shut out of bond markets and with bailout aid locked, cash-strapped Athens has been scraping state coffers to meet debt obligations and to pay wages and pensions. With its future as a member of the 19-nation eurozone potentially at stake, a second government minister accused its international lenders of subjecting it to slow and calculated torture.

Hubble Discovers a Fast-Aging Star Nicknamed "Nasty 1" 27

Posted by samzenpus
from the vanity-plate-ideas dept.
An anonymous reader writes: Using NASA's Hubble Space Telescope, Astronomers have uncovered surprising new clues about a large, rapidly aging star whose behavior has never been seen before. The star is so strange in fact that astronomers have nicknamed it "Nasty 1," a play on its catalog name of NaSt1. Wolf-Rayet stars like NaSt1 are typically large, rapidly evolving stellar bodies that form by shedding their hydrogen-filled outer layers quickly, exposing a bright hot, helium-burning core. Nasty 1 is unique because it contains a disk like structure. "We were excited to see this disk-like structure because it may be evidence for a Wolf-Rayet star forming from a binary interaction," said Jon Mauerhan of UC Berkeley, lead author on the new Nasty 1 paper. "There are very few examples in the galaxy of this process in action because this phase is short-lived, perhaps lasting only a hundred thousand years, while the timescale over which a resulting disk is visible could be only ten thousand years or less."

Machine That "Uncooks Eggs" Used To Improve Cancer Treatment 38

Posted by samzenpus
from the closer-to-a-cure dept.
hypnosec writes: An Australian invention that gained attention for being able to "unboil" an egg has now been put to use in the treatment of cancer. The device has boosted the potency of a common cancer treatment drug, carboplatino, as much as four-and-a-half-times. ABC.net reports: "Flinders Centre for Innovation in Cancer director Professor Ross McKinnon said it meant a huge advance for cancer treatment. 'It gives us the promise of offering an alternative where we have more drug being delivered to the tumour and less drug being delivered to the rest of the body,' he said. 'That means less side-effects for the patient and hopefully a much better effect in terms of tumour response. What this group are doing is an example of one drug but we would hope we could extend this to many drugs.' The device can process proteins more efficiently than current methods, with possible big ramifications for the pharmaceuticals industry.

This is now. Later is later.
