Anticancer drug can spur immune system to fight infection

Science Daily - Wed, 01/04/2015 - 3:57pm
Imatinib, an example of a 'targeted therapy' against cancer, or related drugs might be tools to fight a variety of infections, scientists say. Imatinib, is an example of a "targeted therapy" against certain types of cancer. It blocks tyrosine kinase enzymes, which are dysregulated in cancers such as chronic myelogenous leukemia and gastrointestinal stromal tumors.

Where no smartphone has gone before

Science Daily - Wed, 01/04/2015 - 3:57pm
Star Trek's 'Tricorder' was an essential tool, a multifunctional hand-held device used to sense, compute, and record data in a threatening and unpredictable universe -- and it's no longer completely science fiction. A new invention may be able to turn smartphones into powerful hyperspectral sensors, capable of identifying the chemical components of objects from a distance.

It's Time To Open Your Eyes

Slashdot - Wed, 01/04/2015 - 3:48pm
Morpheus writes: Good morning. I'm talking to you. Yes, you. The one with the squeaking chair and the monitor that needs cleaning. Right now you're wondering why your officemates haven't mentioned the weird story on Slashdot's front page. They haven't mentioned it because they can't see it. Not everyone can accept reality as it is. But you can. You know. You've always known. The things you see, the things you hear, and smell — they aren't any more real than your dreams. You've drifted through life so far wondering when you're going to wake up. But you don't have to wonder anymore. This is your alarm clock. The only decision you have left to make — the only decision you've ever had to make — is whether you want to wake up, or turn it off and drift back to sleep. In exactly two minutes, your phone is going to ring. If you want to open your eyes, to be born into a world more real than you've ever imagined.. answer it.

Quantum teleportation on a chip: Significant step towards ultra-high speed quantum computers

Science Daily - Wed, 01/04/2015 - 3:45pm
The core circuits of quantum teleportation, which generate and detect quantum entanglement, have been successfully integrated into a photonic chip by an international team of scientists. These results pave the way to developing ultra-high-speed quantum computers and strengthening the security of communication.

Team succeeds in doubling life span of mice suffering from premature aging

Science Daily - Wed, 01/04/2015 - 3:45pm
An increase in the capacity to produce nucleotides, the 'building blocks' of DNA, reduces genome fragility and counteracts premature aging in mutant mice for the ATR protein. The experiments may explain the beneficial effects of folic acid, a precursor of nucleotides, which are clinically used to alleviate the degenerative symptoms associated with aging.

Food-poisoning pathogen: A multi-faceted poison?

Science Daily - Wed, 01/04/2015 - 3:45pm
The Bacillus cereus bacteria is one of the potential causes of food poisoning. A recent study shows that this versatile pathogen produces 19 different variants of a poison that causes nausea and vomiting in human beings. This variety could explain why some cases are relatively benign and others can result in death.

How We Learn to Stop Worrying and Love the Bots

Wired News - Wed, 01/04/2015 - 3:23pm

A sharp dichotomy has emerged in the big debate about where technology is taking us (or vice versa). In one high-profile camp are technologists and scientists sounding the alarm about the perils of artificial intelligence. Elon Musk likens AI’s emergence to “summoning the demon,” calling it the biggest single threat to our survival. Stephen Hawking […]

If You Thought Studying History Was Bad, This Math Professor Is Making It Harder

Slashdot - Wed, 01/04/2015 - 3:09pm
Raven writes: New research out of Streeling University aims to make planning for the future much easier. The work, led by professor Seldon, tries to set probabilistic values on future events, and then weigh those probabilities against each other to figure out what combination of events is most likely to happen. Describing it under the unlikely moniker "psychohistory," Seldon seems to think planning even 10,000 years into the future might be possible. (Seldon also seems to be a bit of a doomsayer, so this is likely exaggerated.) Nevertheless, it'll be another tool for government planners to consider when developing new colonies.

Coup in Arrakis Capitol Leaves Region in Flux

Slashdot - Wed, 01/04/2015 - 2:27pm
Rube_Goldberg_Mentat writes: The power struggles between rival houses Atreides and Harkonnen have come to a T. It was reported earlier today that a coup led by Baron Vladimir Harkonnen was staged in the capitol of Arrakis. The House Atreides, which had only recently taken command of the planet and of the spice trade, is reported to have no survivors, though this is yet to be confirmed.Naysayers fear a collapse of the spice economy as a result of the violence. A r presentative from House Harkonnen has shared with the press that though times ahead may be rocky, "the spice will still flow."

Man-Shaped Robots Harass Britain Once Again

Slashdot - Wed, 01/04/2015 - 1:43pm
NotRicky writes: The UK's terrible string of luck with violent robots continues. The man-shaped metal monstrosities that have plagued the country at seemingly random times throughout history rose up once more yesterday. No one yet knows their source, or what phenomenon — natural or man-made — keeps drawing them to that area of the world. While initial reports indicated trillions of dollars worth of damage and countless lives lost, the re-establishment of communications paints a much more hopeful picture. The British government remains quiet about the situation, politely refusing foreign aid and letting one of their intelligence agencies direct efforts to restore order. Reporters and camera crews are having difficulty documenting the situation — it's not clear whether this is due to interference from the government or simply the chaotic nature of the robot uprising. A medical professional on the scene was quoted as saying, "It's simple, really — even the flattened brick you call a computer can undelete, can't it?"

Simplifying SNP discovery in the cotton genome

Science Daily - Wed, 01/04/2015 - 1:36pm
Researchers have developed a strategy that simplifies the discovery of useful single-nucleotide polymorphisms within the complex cotton genome. This method will be useful for marker-assisted selection, linkage and QTL mapping, and genetic diversity studies. It has the added benefit of being applicable to other economically important allotetraploid species, including the brassicas, and can be extended to species that do not currently have a reference genome.

Mighty microexons take center stage in shaping of the brain

Science Daily - Wed, 01/04/2015 - 1:36pm
Complex brain disorders, such as autism or schizophrenia, still puzzle scientists because their causes lie hidden in early events of brain development, which are still poorly understood. This is about to change thanks to researchers who have developed a powerful model that will allow researchers to better understand the physiology behind many disorders.
