A lot of media (BBC, Gizmodo (and a lot of others) report that a man was cured of HIV by a bone marrow transplant: It's wonderful scientists / doctors continuously keep getting closer to curing HIV. Obviously, there is a lot of work to be done... but I have to say that this seems the most promising bit of news in many years.

Can this really be true? According to this article the God particle has been found at last My link

I am doing nitric oxide measurement using aorta tissue.I had go through some articles that stated that the tissues were frozen with liquid nitrogen and stored at -80 degree Celsius, then homogenates and continue to assay. Anyone can tell me that if i use the fresh tissues, incubate with drugs, then can i directly homogenates it and continue to the assay instead of store it at -80 degree Celsius before the assay? Thank you very much.

The end of space is pure white. It's white EVERYWHERE! There is nothing but endless light!

"A quantum take on certainty: Physicists show that in the iconic double-slit experiment, uncertainty can be eased." http://www.nature.com/news/2011/110602/full/news.2011.344.html and at SciAm "New 'Double Slit' Experiment Skirts Uncertainty Principle" http://www.scientifi...ainty-principle and "it is not necessary to interpret the uncertainty principle as rigidly as we are often taught to do" from the article itself and quoted in than the editorials Does anyone have access to the article? I rather thought that the HUP was a black and white thing with no grey areas. So can you relax the HUP - or interpret it less than rigidly? Surely σxσp≥h/4…

Scientists have figured out a way to possibly inhibit age-related macular degeneration. Two miRNAs have been isolated that when inhibited, will prevent extensive blood vessel growth.

Awesome.

Scientists have produced the world's most powerful optical microscope, which could help us to understand the causes of many diseases. Writing in the journal Nature Communications, the team have created a microscope which shatters the record for the smallest object the eye can see, beating the diffraction limit of light. Previously, the standard optical microscope could only see items around one micrometer -- 0.001 millimeters -- clearly. But now, by combining an optical microscope with a transparent microsphere, dubbed the 'microsphere nanoscope', the Manchester researchers can see 20 times smaller -- 50 nanometers ((5 x 10-8m) -- under normal light. This is beyond t…

Deep-Earth devil worms A newly identified species of nematode lives miles deep in the tight, hot crevices of the Earth's crust Halicephalobus mephisto Property of the University Ghent, Belgium - Gaetan Borgonie Scientists have identified a new species of microscopic worms living in the ground below South African mines, isolated from fracture water gushing up from miles below the Earth's surface. It is the first multicellular organism to be found at such depths. The discovery of the tiny nematode (named Halicephalobus mesphisto after Mephistopheles, a literary nickname for the Devil), published in this week's issue of Nature, challenges the assum…

So a German Mathematician, Gerhard Opfe, released a pre-print in which he claims to have prove the veracity of the Collatz Conjecture. The paper has not yet been accepted for publication, but it is getting some notice on the internet. "An Analytic Approach to the Collatz 3n+1 Problem"

Hydrocarbons Deep Within Earth: New Computational Study Reveals How A snapshot taken from a first-principles molecular dynamics simulation of liquid methane in contact with a hydrogen-terminated diamond surface at high temperature and pressure. The spontaneous formation of longer hydrocarbons are readily found during the simulations. (Credit: Eric Schwegler, Lawrence Livermore National Lab) ScienceDaily (Apr. 17, 2011) — A new computational study published in the Proceedings of the National Academy of Sciences reveals how hydrocarbons may be formed from methane in deep Earth at extreme pressures and temperatures. http://www.sciencedaily.com/releases/2011/…

A device helps a man paralyzed from the waist down make an 'unprecedented' recovery, taking steps on a treadmill and regaining other key functions. The treatment could potentially allow 10% to 15% of people with spinal cord injuries to regain some use of their legs.

http://www.dailytech.com/Richard+Branson+Announces+Virgin+Oceanic+Submarine+/article21307.htm The official website is here: http://www.virginoceanic.com/ It's worth noting that the Marianas Trench, the deepest part of the ocean, is only 36,000 feet deep; Branson's vessel (which has already been built) will be able to explore any part of the ocean floor. There has only ever been one manned vessel to reach the bottom of the Trench -- the Trieste. If Branson pulls this off, it will almost certainly be pretty awesome. Damn, I want to be fabulously rich so I can build myself a submarine.

Ant age Amp Md is a newly lunched technology by Rodan + field Anti age which removes wrinkles and blotches and all the age factor effects which causes due to old age.It has been available for general public since October 2nd,.2010.

The study is the world's first investigation of how real-time functional Magnetic Resonance Imaging (fMRI) feedback from the brain region responsible for higher-order thoughts, including introspection, affects our ability to control these thoughts. The researchers find that real-time brain feedback significantly improves people's ability to control their thoughts and effectively 'train their brains.' "Just like athletes in training benefit from a coach's guidance, feedback from our brain can help us to be more aware of our thoughts," says co-author Prof. Kalina Christoff, UBC Dept. of Psychology. "Our findings suggest that the ability to control our thinking improves …

Easily distracted people can stop blaming their lack of focus on the royal wedding, Facebook feeds and hilarious YouTube videos of honey badgers. Rather, a small network of cells in the back left part of the brain may be the culprit, researchers report in the May 4 Journal of Neuroscience. Knowing how the brain focuses on what’s important — and filters out noise — may help scientists come up with ways to counteract attention disorders. “Attention has a huge effect on our lives,” says cognitive neuroscientist Carmel Mevorach of the University of Birmingham in England, who was not involved in the study. “Everything we do — literally, everything we do — is affected b…

It can take smarts to survive in the big city. Especially for birds. The urban environment is very different from the one in which their ancestors were born and fledged. But do city birds really need more gray matter to make it? Scientists surveyed 82 species of passerine birds, including sparrows and anything that perches, in and around 12 cities in central Europe.* They classified the birds as those that breed in the heart of the city or those that avoid the hustle and bustle. And then they compared the bird brains.The results? Birds that prosper on the city streets have larger brains than their pastoral relations. So it seems that novel environments, including urb…

Seemed like a good idea at the time.

Jump in Communication Skills Led to Species Explosion in Electric Fishes In the top group of fishes, species in the genus Paramoryrops that has the complex signal-processing brain, discharges have changed quickly, resulting in dramatically different pulses among closely related species. In the bottom group of fishes, species in the genus Petrocephalus whose midbrain is more simply structured, all of the species have similar pulses. The difference arises because the top group has the anatomical features needed to exploit the signal space -- such as the anatomy needed to make different pulses and the sensory and analytical ability to perceive small differences in puls…

http://www.gizmag.com/new-material-steel-plastic/18013/ Apparently, it is now possible to combine the strength of metals with the flexibility of plastics. However, these new materials still require large amounts of expensives metals for synthesis...even so, might be a useful intermediate along the way to developing organic polymers with the same strength properties.

A fun little something to share with your friends/freaked-out relatives. As a somewhat-related side comment, the manager of my local food co-op (I live in Michigan, mind you--Michigan) said that she'd had several people coming in aiming to buy up all of the sea kelp supplements, with the intention of preventing radiation poisoning. She'd said a friendly e-mail had come across the national co-op listserv with some helpful information to provide such customers: to properly saturate your thyroid enough to prevent iodine uptake, you'd need approximately ten bottles of the stuff. Oh yeah, and also, the sidewalk concrete is currently flooding us here in f#%*ing Michigan w…

I was wondering what peoples opinions were on this kid: http://www.indystar.com/article/20110320/LOCAL01/103200369 i know next to nothing in mathematics and physics so i have no gauge on how far along he actually is compared to his peers (university level) or how much potential he has, but he sounds impressive enough to a layperson. are people like him rare, or is this something (slightly) more common that the media is playing up? does being a prodigy really give the person a benefit over an entire career, or does it just put them at a headstart, before his catch up? also the reporter is a little grating, just bear with it lol.
