Researchers have repaired large muscle wounds in mice by growing and implanting "microthreads" coated with human muscle cells. The microthreads—made out of the same material that triggers the formation of blood clots—seem to help the cells grow in the proper orientation, which is vital for rebuilding working muscle tissue.

Who put the microchip in my benadryl?
Swiss pharmaceutical company Novartis AG is developing a pill containing an embedded microchip, which it hopes to submit for regulatory approval in Europe within 18 months.
The chip is activated by stomach acid and transmits information to a patch attached to the patient’s skin, which then sends it on to a doctor via the Internet or a smartphone.

A Long-Lasting Universal Flu Vaccine
For decades, researchers have been doggedly pursuing a universal flu vaccine--one that would protect against the evolving influenza virus for years rather than just a single season--with little success. The bug mutates so quickly that a new vaccine must be specially formulated each year. But a relatively new strategy, targeting a rarely seen portion of the virus, is now showing some success.
While vaccines for other infections can create immunity that lasts for decades, the flu virus has proved a more challenging adversary. Because the human immune system is so adept at recognizing it, the virus has evolved the ability to modify its most recognizable protein--called hemagglutinin--from year to year. So every year, six months prior to flu season, the U.S. Food and Drug Administration devises the country's annual vaccine according to its best guess for which strains will be most virulent. And every year, we need another flu shot.
Palese's experimental vaccine, however, targets a part of the hemagglutinin protein that remains relatively stable over time, enabling its broad immunizing effects.
Making a Genome Quickly from Scratch
A rapid DNA-synthesis technique has been used to synthesize a complete mitochondrial genome from scratch. The new method will be used to make vaccines rapidly by a startup company called Synthetic Genomics Vaccines.

Yet another step towards a television free world
Miniature device could allow a cell phone to project images on a wall | KurzweilAI
A new one-cubic-centimeter projector head that can be integrated into a portable computer or mobile telephone has been developed by Lemoptix, a spin-off of Ecole Polytechnique Federale de Lausanne (EPFL), and the Maher Kayal Laboratory.
A new one-cubic-centimeter projector head that can be integrated into a portable computer or mobile telephone has been developed by Lemoptix, a spin-off of Ecole Polytechnique Federale de Lausanne (EPFL), and the Maher Kayal Laboratory.
The projector uses very little energy, requiring on average 30% less current than the matrix- or LED-based technology currently available on the market. It should be available in 2011 for industrial applications, and the following year for consumer electronics, according to Nicolas Abelé, Technical Director of the start-up.

Technology Review: Artificial Ovary Could Help Infertile Women
First time that a 3-dimensional environment containing the three main types of ovarian cells: theca cells, granulosa cells, and the eggs (oocytes) has been developed. Immediate importance in studying fertility, environmental and pharmaceutical impacts, contraceptive development, and ovarian cancer with future clinical potential in harvesting and maturing eggs safely for infertile women.

Screw polysporin, give me some fibronectin for my owie
Harvard scientists have developed a fabric coated with a protein called fibronectin which has the potential for helping wounds heal quickly sans scarring or possibly as a scaffold for growing organs.

Hilarious video of animals getting drunk from fermented fruit.
Good for a chuckle
A woman went to a pet shop and immediately spotted a large, beautiful parrot. There was a sign on the cage that said $50.00.
"Why so cheap?" she asked the pet store owner.
The owner looked at her and said, "Look, I should tell you first that this bird used to live in a house of prostitution, and sometimes it says some pretty vulgar stuff."
The woman thought about this, but decided she had to have the bird anyway. She took it home and hung the bird's cage up in her living room and waited for it to say something.
The bird looked around the room, then at her, and said, "New house, new madam." The woman was a bit shocked at the implication, but then thought, "That's really not so bad."
When her two teenage daughters returned from school, the bird saw them and said, "New house, new madam, new girls."
The girls and the woman were a bit offended but then began to laugh about the situation considering how and where the parrot had been raised.
Moments later, the woman's husband Eric came home from work The bird looked at him and said, "Hi, Eric."

Worse than an oil spill...farming
The Other Gulf Stain - Dot Earth Blog - NYTimes.com
As if the BP oil spill didn't cause enough damage to the coastal areas of the Gulf of Mexico, large amounts of nitrogen and other nutrients from midwest agricultural lands has washed down the Mississippi river and entered the Gulf.
So...what are the repercussions of this?
The abundance of nutrients causes a dramatic increase in the plant life initially (e.g. algal bloom) but then creates what is known as a 'hypoxic zone' or 'dead zone' as all the oxygen dissolved in the water gets used up by the photosynthesizing plants. This has huge ramifications for the animal life in those areas, and could be costlier to the ecosystem and the Gulf fishing economy than the BP oil spill.

The end of tv
I knew it was only a matter of time before televisions (even 100" plasma LCD HD ones) would go extinct and I think the beginning of the end has begun. A new portable projector from Tumi can be used on "most video-enabled MP3 players, the Apple iPhone and laptop computers." With the ever-expanding market of online viewing (Hulu, ESPN3, Netflix, etc...) it's only a matter of time before all you'll need for in-home entertainment is an internet connection, a laptop/iPhone, and a wall.
