Submission + - NVIDIA found a way to quadruple display performance in low-res LCDs

mrspoonsi writes: Problem: how do they manufacture low-cost products with high-resolution screens? NVIDIA researchers have one solution — stack two low-resolution panels on top of each other to increase pixel density on the cheap. The solution is so simple it sounds ridiculous, but apparently, it works. Researchers disassembled two 1,280 x 800 LCD panels and rebuilt them into a single display with slightly offset pixels, a filter to weed out polarization conflicts and a bit of customized software to force the display components to work in tandem. NVIDIA calls the resulting prototype a "cascaded display," and in tests it has quadrupled the spatial resolution of the original panels (thanks, in part, to how the pixel offset crams an additional four pixels behind every one of the first panel's visible pixel).

Submission + - New protein structure could help treat Alzheimer's, related diseases (washington.edu)

vinces99 writes: There is no cure for Alzheimer’s disease and other forms of dementia, but the research community is one step closer to finding treatment. University of Washington bioengineers have a designed a peptide structure that can stop the harmful changes of the body’s normal proteins into a state that’s linked to widespread diseases such as Alzheimer’s, Parkinson’s, heart disease, Type 2 diabetes and Lou Gehrig’s disease. The synthetic molecule blocks these proteins as they shift from their normal state into an abnormally folded form by targeting a toxic intermediate phase. The discovery of a protein blocker could lead to ways to diagnose and even treat a large swath of diseases that are hard to pin down and rarely have a cure.

“If you can truly catch and neutralize the toxic version of these proteins, then you hopefully never get any further damage in the body,” said senior author Valerie Daggett, a UW professor of bioengineering. “What’s critical with this and what has never been done before is that a single peptide sequence will work against the toxic versions of a number of different amyloid proteins and peptides, regardless of their amino acid sequence or the normal 3-D structures.”

Submission + - The five greatest space hacks of all time

Esther Schindler writes: Space missions are amazingly well-prepared affairs, every action and procedure is followed, right down to the most minute detail. But sometimes mishaps and emergencies occur. Some can be dealt with by sophisticated sensors and equipment. Some can be dealt with on Earth from Mission Control. But sometimes the only option is for an astronaut to get their hands dirty, using whatever comes to hand and a bit of DIY know-how. It’s amazing what has been grabbed, bent and improvised to save red faces – or, indeed, the lives of astronauts.

Anyone who says Israel have left Hamas no choice is both morally _and_ intellectually bankrupt !!

You didn't watch the video, did you, Mr. Anonymous Coward? The guy in it is the son of an Israeli general who was pretty much a hero to the Israelis, and who in his later life became devoted to the cause of peace and was very much against Israel's treatment of the Palestinians. His son, (the guy in the video), lost a beloved 14-year-old niece in a Palestinian attack, yet he is critical of his own government's role in the environment that led to her death, and has managed to make friends among the Palestinians.

These are people who have a serious amount of skin in this game, yet they have risen above their own knee-jerk reactions, thrown off the propaganda they've been exposed to, and made a hard choice to try to heal the wounds and bury the hatchet. Sure, Hamas' actions are evil - but can you see that your actions might be over the top if you were forced into the shit-end of an apartheid relationship and saw your children not having enough food, water, and education as a result? If you had decades of being demeaned and treated as second-class citizens, with the same for your kids, with no end in sight?

The point here is not about who's right, who's wrong, who's better, who's worse. It's about atrocities having been committed by both parties, and about stopping that shit for the good of all of us. It's easy to stand on the sidelines and engage in name-calling. It's hard to get on the battlefield and fight. But the hardest thing by far is to forgive and to try to move forward when some of the bodies on the field belong to your family. The world needs more people who choose the hardest road - I hope I never have to make that choice, but if I do, I sure as hell hope that I take the hardest path.

Responses like yours only serve to escalate conflicts, add fuel to a fire that's already out of control, and encourage propagandists and tyrants. And don't assume that you'd be so different from Hamas if you were put into the same situation. Desperation makes people do things they never thought they would or could, and I seriously doubt you're very much different from the rest of us in that regard.

...Hamas really is "the bad guys"...

Did you ever stop to wonder if perhaps Hamas are "bad guys" because the Israelis have really left them no choice?

If you watch the entire video while maintaining a little intellectual honesty, you won't be so quick to condemn Hamas as being so much worse than the Israelis. There's plenty of evil in that region, and Israel is both directly and indirectly responsible for a very large part of it.

Submission + - How The Internet Of Things Could Aid Disaster Response (itworld.com)

jfruh writes: While the Internet has made communications easier, that ease had made us very dependent on the Internet for communications — and, when disaster strikes, power and infrastructure outages tend to shut down those communications networks when we need them most. But now researchers are examining how the so-called "Internet of Things" — the proliferating array of Internet-communicating devices in our lives — can transmit emergency messages via ad-hoc networks even when the Internet backbone in a region is inoperable.

Submission + - Potentially Immortal Single Cell Life form Eats, Breathes, Electrons (newscientist.com)

retroworks writes: University of Southern California, Los Angeles researchers are studying forms of bacteria, found on the sea bed, which can feed directly on electrons from electric current. Unlike any other living thing on Earth, electric bacteria use energy in its purest form – naked electricity in the shape of electrons harvested from rocks and metals. NewScientist reports on cells which make ATP, a molecule that acts as an energy storage unit for almost all living things. This life form needs no sugar or protein, it can consume electrons, from electricity, directly.

"To grow these bacteria, the team collects sediment from the seabed, brings it back to the lab, and inserts electrodes into it. First they measure the natural voltage across the sediment, before applying a slightly different one. A slightly higher voltage offers an excess of electrons; a slightly lower voltage means the electrode will readily accept electrons from anything willing to pass them off. Bugs in the sediments can either "eat" electrons from the higher voltage, or "breathe" electrons on to the lower-voltage electrode, generating a current. That current is picked up by the researchers as a signal of the type of life they have captured."

Aren't you make that mistake yourself?

No, he's not making the same mistake. He's perfectly willing to let others use the new design and features - he just wants a way to keep the old behaviour, and so do I.

That leads to an explosion of difficult-to-understand checkboxes in the UI, and an unmaintainable mess under the hood.

I'm not very well qualified to comment on the 'unmaintainable mess', but it smells fishy to me. If Pale Moon can keep the old behaviour while incorporating the new security enhancements, surely Mozilla can keep the old UI and the new one without compromising maintainability. Especially since addon designers have been doing pretty much that for your users for 25 or more releases. And as for the 'difficult to understand check boxes', scratch them. Just give us a well documented set of 'about:config' entries that are already present and prefixed with something like "old behaviour" so can go to one block of entries, change them all, and be done. Heck, you could boil it down to ONE entry called 'browser.pre_australis_mode'.

I'm pretty sure that won't happen though, not because it's too much work, but because Mozilla is hell bent on me-tooing their way into the future with all the other browser makers whose attitude is 'screw the users'. So in the meantime I'm using Pale Moon. Yes, I see the apparent hypocrisy in that decision. I hope Mozilla sees the hypocrisy of bringing private corporation attitudes to their ostensibly FOSS organization.

I'll install it when that godawful Australis interface is rolled back or replaced with something less eye-bleedingly bad

If enough of us move to Pale Moon, (it's all I've used since shortly after Australis first shat all over my computer screen), then perhaps Mozilla will get the hint that we love Firefox, but hate what it's become. And if they don't get the hint, well, then we're supporting a viable alternative for the time when Mozilla gets eaten by the shark it just jumped.

BTW, although the Linux version of Pale Moon is 'unofficial' and maintained by somebody outside the organization, I've had no trouble running it under Debian Jessie with all of my usual addons.

Comment With all this progress on HIV, (Score 1) 64

I'm astonished that they haven't made more progress on cancer. I know it's like comparing apples and oranges, and I realize that cancer is a whole bunch of diseases while HIV is a handful of strains of the same virus. Still, cancer research has been very heavily funded for far longer than HIV research. Yet it seems that very little progress has been made on cancer beyond 'cut it out, poison it, nuke it', while attempts at eliminating HIV seem more subtle and nuanced by comparison. I know I'm probably missing something important here; anyone care to enlighten me? TIA.
