IHateEverybody writes “Scientists have found evidence that the solar wind is ripping off chunks of the Martian atmosphere, which could possibly explain why Mars has such a thin atmosphere today. The chunks are being ripped up along ‘magnetic umbrellas,’ which are bubbles of magnetic fields which rise from the ground and extend above the Martian atmosphere. This is surprising because scientists previously thought that these magnetic umbrellas protected the Martian atmosphere. Now it looks like exactly the opposite might be true.”

Matt_dk writes “An international team of scientists who analyzed data from the Gamma Ray Spectrometer onboard NASA’s Mars Odyssey reports new evidence for the controversial idea that oceans once covered about a third of ancient Mars. We compared Gamma Ray Spectrometer data on potassium, thorium and iron above and below a shoreline believed to mark an ancient ocean that covered a third of Mars’ surface, and an inner shoreline believed to mark a younger, smaller ocean.”

Toren Altair writes with this excerpt from a story at The Space Fellowship: “NASA’s Mars Exploration Rover Spirit communicated via the Mars Odyssey orbiter today right at the time when ground controllers had told it to, prompting shouts of ‘She’s talking!’ among the rover team at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. ‘This means Spirit has not gone into a fault condition and is still being controlled by sequences we send from the ground,’ said John Callas of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., project manager for Spirit and its twin, Opportunity.”

reporter writes “HIV is the virus that causes Acquired Immune Deficiency Syndrome (AIDS). Until now, HIV has no cure and has led to the deaths of over 25 million people. However, a possible cure has appeared. Dr. Gero Hutter, a brilliant physician in Germany, replaced the bone marrow of an HIV patient with the bone marrow of a donor who has natural immunity to HIV. The new bone marrow in the patient then produced immune-system cells that are immune to HIV. Being unable to hijack any immune cell, the HIV has simply disappeared. The patient has been free of HIV for about 2 years. Some physicians at UCLA have developed a similar therapy and plan to commercialize it.”

Khemisty writes “Back in grade school you were probably taught the importance of warm-up exercises, and it’s likely you’ve continued with pretty much the same routine ever since. Science, however, has moved on. Researchers now believe that some of the more entrenched elements of many athletes’ warm-up regimens are not only a waste of time but are actually bad for you. The old presumption that holding a stretch for 20 to 30 seconds &mdash known as static stretching &mdash primes muscles for a workout is dead wrong. It actually weakens them. In a recent study conducted at the University of Nevada, athletes generated less force from their leg muscles after static stretching than they did after not stretching at all. Other studies have found that this stretching decreases muscle strength by as much as 30 percent. Also, stretching one leg’s muscles can reduce strength in the other leg as well, probably because the central nervous system rebels against the movements.”

Scientists at the University of California Los Angeles are reporting that while some people may think “life begins at 40,” all it seems to do is slow down. According to recent research, at age 39 our brain reaches its peak speed, and it’s all down hill after that. “The loss of a fatty skin that coats the nerve cells, called neurons, during middle age causes the slowdown, experts say. The coating acts as insulation, similar to the plastic covering on an electrical cable, and allows for fast bursts of signals around the body and brain. When the sheath deteriorates, signals passing along the neurons in the brain slow down. This means reaction times in the body are slower too.”

CWmike writes “Ever picked up a cold, frosty beer on a hot summer’s day and thought that it simply couldn’t get any better? Well, think again. A team of researchers at Rice University in Houston is working on helping Joe Six Pack fight aging and cancer with every swill of beer.” Thank you science! Now we just need cigarettes that cure baldness.

Amenacier writes “Melbourne scientists recently discovered that stem cells isolated from human fat could be made to turn into beating heart muscle cells when cultured with rat heart cells. This discovery may lead to the use of fat stem cells in repairing cardiac damage, or fixing such cardiac problems as holes in the heart. It is proposed that culturing the stem cells with rat heart cells allows them to differentiate into heart muscle through signals from the rat cells. In the future it may be possible to inject/transplant the stem cells into the damaged area and have them naturally differentiate into the type of cell required, with only the natural stimuli provided by surrounding cells, without any danger of rejection by the body. Quoting: ‘The next step is to implant the human heart cells onto the damaged heart of a laboratory rat to see whether they repair the heart. Then they would be trialled in higher species such as sheep and pigs before human applications could be considered. Clinical application could be five years away …’” The Age has a multimedia treatment (Flash) of the discovery.

An anonymous reader writes “Serious heart surgery usually involves stopping the organ and keeping the patient alive with a cardiopulmonary bypass machine. But this risks brain damage and requires a long recuperation. Scientists at Harvard University and Children’s Hospital Boston have now developed a device that lets surgeons operate on a beating heart with a steady hand. The ‘robotic’ device uses 3-D ultrasound images to predict and compensate for the motion of the heart so that the surgeon can work on a faulty valve as it moves. The approach should improve recovery times and give a surgeon instant feedback on the success of the procedure, the researchers say. Here’s a (slightly gory) video of the device in action.”

LaserGames is a mod for projectors allowing up to two players to interact with a game using a run-of-the-mill (red or green) laser pointer in place of a mouse or controller, minus the precision response. Developer Alpay Kasal of Lit Studios isn′t giving any hints on how this thing works, but we imagine it uses sensor technology similar to interactive projections — you know, the ones where a video is projected on the ground and you get to kick around a soccer ball and then watch some tacky Nokia ad at the end. If you′re up for trying this out first hand, Kasal’s prototype will soon be on public display for some wild and crazy retina burning action — no word yet on when or where. Check out his video after the jump.

We know — there’s a certain sect of you out there that just goes bonkers whenever a new mouse and / or keyboard is released. Unfortunately, we’ll be catering to the other 99% with this one. Alongside a few new laptops, a new desktop and a pair of digiframes, HP is also unveiling a whole host of input peripherals this evening. Up first is the HDX Laser Mouse, which features five programmable buttons, on-the-fly DPI switching up to 2,400, five individual setting profiles and USB 2.0 connectivity. Next up is the Wireless Comfort Desktop, which includes a spill-resistant Wireless Comfort Keyboard, a Wireless Vector Mouse (800 DPI), a USB wireless receiver and four AA batteries (imagine that!). Last, we′ve got the Laser Gaming Mouse with VoodooDNA, which cranks the DPI up to 3,200 and includes VoodooDNA GUI software. As for pricing, you’re looking at $39.99, $79.99 and $59.99 in order of mention.

It’s a mouse, it’s a television remote control — really, besides a bag of chips and a great Belgian lager like Budweiser, what else is needed for a sedentary lifestyle? The C@T-one (get it, cat one?) ships with a 2.4GHz wireless USB dongle and should work with your PC-based media center or FORIS.HD TV. ¥12,600 (about $120), problem solved.
