New discovery may end transplant rejection

Big news in the medical world: scientists in Australia have found a way to stop the body from attacking organ transplants, greatly decreasing the possibility of organ rejection.

The last major hurdle of transplantations is the body itself. When a new tissue is introduced, one’s immune system kicks into overdrive, sending out cells known as killer T cells to attack and destroy the unknown tissue. Because of this, those who receive transplants have to maintain a regime of toxic immune-suppressing drugs.

Star Trek’s Warp Drive: Not Impossible

The warp drive, one of Star Trek’s hallmark inventions, could someday become science instead of science fiction. Some physicists say the faster-than-light travel technology may one day enable humans to jet between stars for weekend getaways. Clearly it won’t be an easy task. The science is complex, but not strictly impossible, according to some researchers studying how to make it happen. The trick seems to be to find some other means of propulsion besides rockets, which would never be able to accelerate a ship to velocities faster than that of light, the fundamental speed limit set by Einstein’s General Relativity.

Diatoms could triple solar cell efficiency

Microscopic algae called diatoms could help triple the electrical output of experimental, dye-sensitized solar cells, according to researchers at Oregon State University and Portland State University.

By trapping light inside the nanoscale pores of thin-film solar cells coated with diatoms, the engineers claim that more incident photons are captured to boost electricity generation, thereby greatly increasing efficiency.

“In our system, photons bounce around inside pores formed from diatom shells,” said OSU professor Greg Rorrer, “making them three times more efficient.”

Military Laser Hits Battlefield Strength Reports: Huge news for real-life ray guns: Electric lasers have hit battlefield strength for the first time — paving the way for energy weapons to go to war.

In recent test-blasts, Pentagon-researchers at Northrop Grumman managed to get its 105 kilowatts of power out of their laser — past the “100kW threshold [that] has been viewed traditionally as a proof of principle for ‘weapons grade’ power levels for high-energy lasers,” Northrop’s vice president of directed energy systems, Dan Wildt, said in a statement.

Scientists Find ‘Baffling’ Link between Autism and Vinyl Flooring

Swedish children who live in homes with vinyl floors are more likely to have autism, according to a new study, but what’s behind the link is unclear. Children who live in homes with vinyl floors, which can emit chemicals called phthalates, are more likely to have autism, according to research by Swedish and U.S. scientists published Monday. The study of Swedish children is among the first to find an apparent connection between an environmental chemical and autism.

Scientists Use DNA to Tether Cells Together, Build Microtissues

One of the greatest hopes in the medical research community is that tissues will one day be grown and implanted into the human body to replace aging or defective tissues and organs. Now researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have developed a novel approach to build self-assembling microtissues by coating cells in complementary DNA.  The new approach is a bottom-up method, which should allow for greater tissue complexity.

A Vaccine Offers Instant Immunity to Cancer and HIV

Barbas and his team developed a two-stage chemical strategy that first puts the body’s antibodies on alert, and then gives them instructions on which targets to destroy. In the first stage, Barbas designed a chemical that, once injected, enables antibodies to form covalent bonds. Normally, antibodies cannot form such bonds. The second stage involves injecting a small adapter molecule with two parts: one that bonds covalently with antibodies, and the other that binds with a specific epitope, or cancer marker. When injected, this adapter molecule links with antibodies and then seeks out and attaches to a target’s specific epitope. The method is essentially like handing antibodies a beeper and putting them on standby. They wait around for a “call,” in the form of the adapter molecule, which, once connected, instantly leads them directly to a target’s weak spot, where the antibody can attack and deactivate the pathogen.

Lockheed offers ready-to-go supersoldier exoskeleton

US weaponry globocorp Lockheed is pleased to announce the unveiling of its newly-acquired powered exoskeleton intended to confer superhuman strength and endurance upon US soldiers. Needless to say, corporate promo vid of the Human Universal Load Carrier (HULC™) is available. There are various optional extras, too. The HULC can be fitted with armour plating, heating or cooling systems, sensors and “other custom attachments”. We particularly liked that last one: our personal request would be a powered gun or missile mount of some kind above the shoulder, linked to a helmet or monocle laser sight.
