+ - Spider spins electrically charged silk->

Submitted by sciencehabit
sciencehabit (1205606) writes "In their quest to make ultrastrong yet ultrasmall fibers, the polymer industry may soon take a lesson from Uloborus spiders. Uloborids are cribellate spiders, meaning that instead of spinning wet, sticky webs to catch their prey, they produce a fluffy, charged, wool-like silk. A paper published online today in Biology Letters details the process for the first time. It all starts with the silk-producing cribellar gland. In contrast with other spiders, whose silk comes out of the gland intact, scientists were surprised to discover that uloborids’ silk is in a liquid state when it surfaces. As the spider yanks the silk from the duct, it solidifies into nanoscale filaments. This “violent hackling” has the effect of stretching and freezing the fibers into shape. It may even be responsible for increasing their strength, because filaments on the nanoscale become stronger as they are stretched. In order to endow the fibers with an electrostatic charge, the spider pulls them over a comblike plate located on its hind legs. The technique is not unlike the so-called hackling of flax stems over a metal brush in order to soften and prepare them for thread-spinning, but in the spider’s case it also gives them a charge. The electrostatic fibers are thought to attract prey to the web in the same way a towel pulled from the dryer is able to attract stray socks."

+ - The American app economy is now 'bigger than Hollywood'

Submitted by Lemeowski
Lemeowski (3017099) writes "Technology business analyst Horace Deidu found an interesting nugget while closely examining an Apple press release from earlier this year: "The iOS App Store distributed $10 billion to developers in 2014, which, Deidu points out, is just about as much as Hollywood earned off U.S. box office revenues the same year." That means the American app industry is poised to eclipse the American film industry. Additionally, Apple says its App Store has created 627,000 jobs, which Deidu contrasts with the 374,000 jobs Hollywood creates"

+ - Dell XPS 13: Smallest 13-inch Notebook With Broadwell-U, QHD+ Display Reviewed->

Submitted by MojoKid
MojoKid (1002251) writes "Dell's 2015 XPS 13 made a splash out at CES this year with its near bezel-less 13-inch QHD+ (3200X1800) display and Intel's new 5th Gen Core series Broadwell-U processor. At 2.8 pounds, the 2015 XPS 13 isn't the absolute lightest 13-inch ultrabook book going but it's lighter than a 13-inch MacBook Air and only a few ounces heavier than Lenovo's Core M-powered Yoga 3 Pro. The machine's Z dimensions are thin, at .33" up front to .6" at its backside near the hinge. However, its 11.98" width almost defies the laws of physics, squeezing a 13.3" (diagonal) display into an 11.98-inch frame making it what is essentially the smallest 13-inch ultrabook to hit the market yet. Performance-wise, this review shows its benchmarks numbers are strong and Intel's Broadwell-U seems to be an appreciable upgrade with lower power consumption."

If you want tuition costs to fall, you have to stop subsidizing education and start creating a competitive market.
Tuition prices have steadily increased with no jumps matching any of the changes matching changes in student loans and grants for both public and private schools. I find it quite funny that you mocked students attending non-state schools with higher than average job placement rates and pay rates and then argue against competitive private schools. Perhaps you would like students to attend schools like Corinthian?

there still is no tuition crisis
Crisis is definitely a weasel word. But call it what you will, inflation adjusted costs doubling is definitely problematic.

Why is that a relevant statistic?
How much more basic can you get than a statistic than students are carrying more debt than before? You could even just have the statistic be for four year schools and eliminate the med school or post docs. The point would remain the same, debts are increasing. Your first article even points to this indirectly by saying that they have increased by current low interest rates and longer payment schemes are keeping the monthly payment the same. We also know that payrates have stagnated and decreased.

Don't argue ad hominem, look at the facts.
That was my entire point. Only selective facts were given.

in the Brookings study: when you look at the statistics
My point is that they don't include all the statistics. Here is a page with only the numbers and no commentary. http://www.pewsocialtrends.org...

These articles use very selective statistics in order to make a point that goes along with the author's political leanings. The first article basically says students are paying the same amount each month because the terms of their loans are longer. The second article looks at households headed in an age range from 20 to 40? This adds in people who did not go to college or are 20 years out to drive down the average debt so the numbers fit the narrative. It doesn't give previous averages either. Why not compare have debt burden of new graduates from previous dates to debt burdens on current graduates.

Adjusted for inflation, average tuition costs have gone up %230 since 1981. http://nces.ed.gov/fastfacts/d... Fill in whatever politics you want around the numbers, but at least be honest with the numbers you are using.

Comment: Climate != single event (Score 2) 222

by Himmy32 (#48604589) Attached to: Linking Drought and Climate Change: Difficult To Do
A seasonal drought is a weather event. The frequency of droughts is climate. Not sure how you can make any claims about climate with one event. This isn't say that climate isn't changing or what is causing it. But that one event is not relevant to the discussion.

No event or small chains of events can ever be proof or unproof of what the climate is or whether it's changing. The whole point of climate is that it's over a long time. So evidence of what happened requires long time scales. But that doesn't mean you can't have predictive models. Evaluating models with data sets is key. But if you think that you can prove or disprove a model with only one data point, you are going to have a bad time. If you want clean proofs, stick with pure math. Inconclusive data and blurred lines are the trademark of applied sciences. Especially ones with many variables.

This is not news. It shouldn't even be a talking point. This is only in the headlines because of how unfortunately politicized this topic has become.
