Gene Therapy Scores Big Wins Against Leukemia, Other Blood Cancers
Post Date: 2013-12-10 00:01:53 by sneakypete
In one of the biggest advances against leukemia and other blood cancers in many years, doctors are reporting unprecedented success by using gene therapy to transform patients' blood cells into soldiers that seek and destroy cancer. A few patients with one type of leukemia were given this one-time, experimental therapy several years ago and some remain cancer-free today. Now, at least six research groups have treated more than 120 patients with many types of blood and bone marrow cancers, with stunning results. "It's really exciting," said Dr. Janis Abkowitz, blood diseases chief at the University of Washington in Seattle and president of the American Society of ...

Human DNA From 400,000 Years Ago Found in Spain
Post Date: 2013-12-05 14:35:18 by Brian S
The oldest human DNA ever found, from a 400,000-year-old thigh bone in Spain, may lead scientists to revise mankinds family tree. The femur from Spains Sima de los Huesos, or Pit of Bones, yielded mitochondrial DNA that showed links between its owner and a group of ancestral humans called Denisovans, according to a study in the journal Nature. The femur bone previously had been thought to belong to the Neanderthals, while Denisovans had been found only in Siberia, about 4,000 miles east of the Spain site, the authors said. The finding suggests that the Denisovans split from the Neanderthals may have occurred from 170,000 to 700,000 years ago, the scientists ...

Impact Theory of Moon's Origin Fails
Post Date: 2013-10-30 20:24:23 by A K A Stone
Secular scientists used to regard the planetary collision theory as a triumph in explaining several of the moon's specific arrangements. But newfound facts severely debilitate this lunar impact origins theory. According to this new theory, an early Earth collided at a glancing angle with a planet that was one or two times the mass of Mars. Some of the debris launched into orbit around Earth and somehow collected to form the moon. This could explain the moon's peculiar orbit and some of its other properties.1 But, as Bob Jones University astronomy professor Ron Samec noted, recent studies refute even this origins scenario.2 For example, ratios of rare titanium forms in moon rocks ...
Newly Found Ancient Skull Could Rewrite Human History
Post Date: 2013-10-17 23:57:21 by Brian S
(CBS News) Humanity's family tree may need some pruning. The discovery of an ancient skull has revealed clues that could shake up the accepted theories of human evolution. From the moment they discovered the skull buried under a village in the former Soviet republic of Georgia, scientists knew they had something applause-worthy. At 1.8 million years old, the skull may do nothing less than rewrite the history of humanity. "It's an almost perfectly complete skull," said Jamie Shreeve, executive science editor for National Geographic, "and because of that, it has a lot of information." "Skull 5," as it's known, belonged to an adult male with a ...
Cyborg Cockroach Company Sparks Ethics Debate
Post Date: 2013-10-08 19:04:52 by A K A Stone
At the TEDx conference in Detroit last week, RoboRoach #12 scuttled across the exhibition floor, pursued not by an exterminator but by a gaggle of fascinated onlookers. Wearing a tiny backpack of microelectronics on its shell, the cockroacha member of the Blaptica dubia specieszigzagged along the corridor in a twitchy fashion, its direction controlled by the brush of a finger against an iPhone touch screen (as seen in video above). RoboRoach #12 and its brethren are billed as a do-it-yourself neuroscience experiment that allows students to create their own cyborg insects. The roach was the main feature of the TEDx talk by Greg Gage and Tim Marzullo, co-founders of ...
This physics grad student made a mind-blowing Bohemian Rhapsody cover
Post Date: 2013-09-18 19:38:47 by A K A Stone
Question: What do you get when you mix a cappella, sock puppets, string theory and Queen? Answer: The geekiest (and astonishingly good, musically speaking) cover of "Bohemian Rhapsody" EVAR. Easily the greatest physics-themed cover of the classic we've ever heard. Seriously. The thing's a masterpiece. To be fair, "Bohemian Gravity" may well be the only physics-themed version of "Bohemian Rhapsody" ever made, but that doesn't change the fact that it is very, very well done. The creation of McGill University Masters candidate Timothy Blaise (who posted this link to his recently submitted thesis, along with the video), the track does way more than ...
Quantum Cryptography – Possible Hope for Stopping NSA Snooping
Post Date: 2013-09-08 12:11:50 by A K A Stone
Now that Snowden has released docs indicting the NSA can crack most regular encryption (like TOR), and most likely can, or will soon, crack most everything, this may be our only hope of reclaiming our communication privacy. Eventually. It harnesses the bizarro-world properties of quantum physics to ensure that information sent from point A to point B isnt intercepted. The laws of physics dictate that nobodynot even the NSAcan measure a quantum system without disrupting it. [...] This kind of communication cannot be defeated by future advances in computing power, nor new mathematical algorithms, nor fancy new engineering, said co-author Andrew Shields, head of ...

The Future of the Automobile
Post Date: 2013-08-14 22:07:24 by jwpegler
Some good friends and I have been having a debate over plug-in electric cars vs. cars powered by fuel cells. They are both electric cars, which are likely the future. The difference is their source of power. Here is the bottom line for me: Yes, Tesla is a superior technology to any other electric car on the road today. Their approach to using a pack of more than 8,000 lithium-ion batteries with computer controlled fail-over instead of one big battery like the Chevy Volt should make GM very ashamed of themselves. Elon Musk and his team are true innovators. But not all innovations succeed. Let me give you an example... 15 years ago I was a big proponent of RFID, because it promised much ...

Too green to be true? Researchers develop highly effective method for converting CO2 into methanol Jun 20, 2013
Post Date: 2013-06-23 18:38:07 by A K A Stone
Université Laval researchers have developed a highly effective method for converting CO2 into methanol, which can be used as a low-emissions fuel for vehicles. The team led by Professor Frédéric-Georges Fontaine presents the details of this discovery in the latest issue of the Journal of the American Chemical Society. Researchers have been looking for a way to convert carbon dioxide into methanol in a single step using energy-efficient processes for years. "In the presence of oxygen, methanol combustion produces CO2 and water," explained Professor Fontaine. "Chemists are looking for catalysts that would yield the opposite reaction. That would allow us to ...
Do you carry DNA of former lovers in your body?
Post Date: 2013-06-20 21:46:23 by A K A Stone
This bit of science arcanum is especially cringe-worthy. Many years ago, scientists first discovered that a large minority of women have Y-chromosome gene sequences in their blood. At first glance, this seems strange. Men are born with Y-chromosomes but most women are not. The male cells in these women mustve come from somewhere else. But where? The most obvious source is a fetus. Nearly every woman who has ever been pregnant or had a baby has cells from her fetus circulating in her bloodstream. These cells filter through the placenta and reside in the mothers bloodstream and/or organs including her heart and brain for the rest of her life. This condition is ...

Scientists Invent Oxygen Particle That If Injected, Allows You To Live Without Breathing
Post Date: 2013-05-08 22:29:49 by A K A Stone
New Medical Discovery A team of scientists at the Boston Childrens Hospital have invented what is being considered one the greatest medical breakthroughs in recent years. They have designed a microparticle that can be injected into a persons bloodstream that can quickly oxygenate their blood. This will even work if the ability to breathe has been restricted, or even cut off entirely. This finding has the potential to save millions of lives every year. The microparticles can keep an object alive for up to 30 min after respiratory failure. This is accomplished through an injection into the patients veins. Once injected, the microparticles can oxygenate the blood to near ...
Climate scientists struggle to explain warming slowdown
Post Date: 2013-04-16 22:39:22 by jwpegler
Scientists are struggling to explain a slowdown in climate change that has exposed gaps in their understanding and defies a rise in global greenhouse gas emissions. Often focused on century-long trends, most climate models failed to predict that the temperature rise would slow, starting around 2000. Scientists are now intent on figuring out the causes and determining whether the respite will be brief or a more lasting phenomenon. Getting this right is essential for the short and long-term planning of governments and businesses ranging from energy to construction, from agriculture to insurance. Many scientists say they expect a revival of warming in coming years. Theories for the pause ...

Birds might be evolving to dodge vehicles
Post Date: 2013-03-18 12:50:54 by Ferret Mike
Fewer cliff swallows are being killed by moving vehicles. Does a new study offer a bird's-eye view into evolution? Fewer cliff swallows are being killed by moving vehicles because of evolution, suggests a study published online today in the journal Current Biology. "These birds have been exposed to vehicles and roads for 30-plus years," says Charles Brown, the study's lead author. "During that time, they have evolved to avoid being killed by traffic. Evolution can happen very rapidly, and some animals can adapt to urban environments very rapidly." The decrease in road deaths is likely because these birds have shorter wingspans, making them more agile fliers, ...
There Used To Be Freaking Camels In The Arctic
Post Date: 2013-03-06 20:00:18 by Ferret Mike
In the northernmost reaches of Canada, within the Arctic Circle, scientists have found fossils of...camels. Wait, what? North America was a crazy place a few million years ago. The megafauna alone would make the world's most awesome zoo collection: giant sloths! Mastodons! Nine-foot saber-toothed salmon! Dire wolves! And, believe it or not, camels. Yes, camels originally arose in North America 45 million years ago and lived there until human migrated into the area around 16,000 years ago. So, we might expect to find camels somewhere in North America, sure. But researchers just found fossils on Ellesmere Island, in the northern territory of Nunavut, Canada, far above the Arctic ...
