Chip Allows Blind People To See 231

crabel writes "3 blind people have been implanted with a retinal chip that allowed them to see shapes and objects within days of the procedure. From the article: 'One of the patients surprised researchers by identifying and locating objects on a table; he was also able to walk around a room unaided, approach specific people, tell the time from a clock face, and describe seven different shades of gray in front of him.'"

40 Million Year Old Primate Fossils Found In Asia 91

sosaited writes "It has been widely believed that our ancestors originated out of Africa, but a paper published in Nature by Carnegie Museum of Natural History scientists puts this in doubt. The paper is based on the fossils of four primate species found in Asia which are 40 million years old, during which period Africa was thought to not have these species. The diversity and timing of the new anthropoids raises two scenarios. Anthropoids might simply have emerged in Africa much earlier than thought, and gone undiscovered by modern paleontologists. Or they could have crossed over from Asia, where evidence suggests that anthropoids lived 55 million years ago, flourishing and diversifying in the wide-open ecological niches of an anthropoid-free Africa."

Assuming, by their name (anti-sense) that these drugs take advantage of the RNA-interference pathway, the molecules used, short interfering RNA (siRNA) don't need to have a 100% specific match to a messenger RNA (mRNA) in order to silence it. When the match is 100%, then the viral mRNA is cleaved (by means of a complex called RISC), and there is no chance of it translating into protein, whereas non-perfect matches don't result in RNA cleavage, but at the same time still block the enzymes that perform the translation (because the siRNA remain stuck to the viral mRNA). Therefore, small mutations in the virus might not have an effect in the drug's efficiency. It's a win-win situation for us.

Possible Treatment For Ebola 157

RedEaredSlider writes "Researchers at the US Army Medical Research Institute of Infectious Diseases have found a class of drugs that could provide treatment for Ebola and Marburg hemorrhagic fever. The new drugs are called 'antisense' compounds, and they allow the immune system to attack the viruses before they can do enough damage to kill the patient. Travis Warren, research scientist at USAMRIID, said while the work is still preliminary -— the drugs have been tested only on primates — the results are so far promising. In the case of Ebola, five of eight monkeys infected with the virus lived, and with Marburg, all survived. The drugs were developed as part of a program to deal with possible bioterrorist threats, in partnership with AVI Biopharma."

Ray Kurzweil Responds To PZ Myers 238

On Tuesday we discussed a scathing critique of Ray Kurzweil's understanding of the brain written by PZ Myers. Reader Amara notes that Kurzweil has now responded on his blog. Quoting: "Myers, who apparently based his second-hand comments on erroneous press reports (he wasn't at my talk), [claims] that my thesis is that we will reverse-engineer the brain from the genome. This is not at all what I said in my presentation to the Singularity Summit. I explicitly said that our quest to understand the principles of operation of the brain is based on many types of studies — from detailed molecular studies of individual neurons, to scans of neural connection patterns, to studies of the function of neural clusters, and many other approaches. I did not present studying the genome as even part of the strategy for reverse-engineering the brain."

His arguments are laughably bad when he strays outside the area he knows (evolutionary biology) and into a region he knows nothing about (theology).

You, sir, need to read The Courtier's Reply :

I have considered the impudent accusations of Mr Dawkins with exasperation at his lack of serious scholarship. He has apparently not read the detailed discourses of Count Roderigo of Seville on the exquisite and exotic leathers of the Emperor's boots, nor does he give a moment's consideration to Bellini's masterwork, On the Luminescence of the Emperor's Feathered Hat. We have entire schools dedicated to writing learned treatises on the beauty of the Emperor's raiment, and every major newspaper runs a section dedicated to imperial fashion; Dawkins cavalierly dismisses them all. He even laughs at the highly popular and most persuasive arguments of his fellow countryman, Lord D. T. Mawkscribbler, who famously pointed out that the Emperor would not wear common cotton, nor uncomfortable polyester, but must, I say must, wear undergarments of the finest silk.

Dawkins arrogantly ignores all these deep philosophical ponderings to crudely accuse the Emperor of nudity.

Personally, I suspect that perhaps the Emperor might not be fully clothed — how else to explain the apparent sloth of the staff at the palace laundry — but, well, everyone else does seem to go on about his clothes, and this Dawkins fellow is such a rude upstart who lacks the wit of my elegant circumlocutions, that, while unable to deal with the substance of his accusations, I should at least chide him for his very bad form.

Until Dawkins has trained in the shops of Paris and Milan, until he has learned to tell the difference between a ruffled flounce and a puffy pantaloon, we should all pretend he has not spoken out against the Emperor's taste. His training in biology may give him the ability to recognize dangling genitalia when he sees it, but it has not taught him the proper appreciation of Imaginary Fabrics.

OH Senate Passes Bill Banning Human-Animal Hybrids 197

An anonymous reader writes "The sci-fi movie Splice seems to have scared the Ohio's State Senator Steve Buehrer. The Ohio Senate has passed Sen. Buehrer's bill banning 'the creation, transportation, or receipt of a human-animal hybrid, the transfer of a nonhuman embryo into a human womb, and the transfer of a human embryo into a nonhuman womb.' So much for Teenage Mutant Ninja Turtles."

Happy Towel Day 122

An anonymous reader writes "While Douglas Adams continues his attempt to set a new record for the longest extended lunch break, geeks all over the universe pay tribute to the beloved author by celebrating the tenth edition of Towel Day. Towel Day is more alive than ever. This year Richard Dawkins, one of Adams' best friends, has tweeted a Towel Day reminder to his numerous followers. The CERN Bulletin has published an article on Towel Day. There has been TV coverage and there will be a radio interview. The Military Republic of the Deltan Imperium, a newly formed micronation, has recognized Towel Day as an official holiday. In Hungary several hundreds of hitchhiker fans want to have a picnic together in a park. And there's a concert, a free downloadable nerdrap album, a free game being released, the list goes on and on."

Cheap Cancer Drug Finally Tested In Humans 363

John Bayko writes "Mentioned on Slashdot a couple of years ago, the drug dichloroacetate (DCA) has finally finished its first clinical trial against brain tumors in humans. Drug companies weren't willing to test a drug they could not patent, so money was raised in the community through donations, auctions, and finally government support, but the study was still limited to five patients. It showed extremely positive results in four of them. This episode raises the question of what happens to all the money donated to Canadian and other cancer societies, and especially the billions spent buying merchandise with little pink ribbons on it, if not to actual cancer research like this."

Crowdsourcing HIV Research 52

biolgeek writes "In recent years, HIV has been managed with a collection of therapies. However, the virus will likely evolve around these drugs, making it crucially important to get a better understanding of the virus itself. An important step in understanding the virus is to get a handle on its genetic blueprint. William Dampier of Drexler University is taking a novel approach to this research by crowdsourcing his problem. He is hosting a bioinformatics competition, which requires contestants to find markers in the HIV sequence that predict a change in the severity of the infection (as measured by viral load). So far the best entry comes from Fontanelles, an HIV research group, which has been able to predict a change in viral load with 66% accuracy."
