Eating Red Meat – Disease causing Bacteria

20071213_redmeat.jpg

And just when steak became your favorite!

Offering another reason why eating red meat could be bad for you, an international research team, including University of California, San Diego School of Medicine professor Ajit Varki, M.D., has uncovered the first example of a bacterium that causes food poisoning in humans when it targets a non-human molecule absorbed into the body through red meats such as lamb, pork and beef.

A Source Of Stem Cells From Men

A Source Of Stem Cells From Men 

 Stem cells from adult human testes normally produce only sperm, but when cultured in the lab with special growth factors, they begin to resemble embryonic stem cells and can differentiate into many adult cell types.

Stem cells from human testes could be used for personalized medicine.  Adult stem cells that behave much like embryonic ones have been isolated from human testes, raising hopes for a new source of versatile stem cells without genetic manipulation or the destruction of embryos. If the new stem cells can be used therapeutically, a simple testicular biopsy could provide the starting material for personalized regenerative medicine.

StarCAVE: Virtual Environment

StarCAVE: Virtual Environment 

UC at San Diego has the closest thing to an X-Men-style Danger Room in its new StarCAVE, a small room that entirely surrounds you, hurtling 68 million pixels at your eyeballs at near-perfect resolution. Pop on polarized glasses and the whole thing goes 3D. Grasping a wireless “wand,” you can walk through tall buildings, fly over cities, pick apart tiny cell structures or embrace entire galaxies. All the while pretending to do actual academic research, of course. Here’s how to build your own for under $1 million:

Pressure-Sensing Contact Lenses To Monitor Glaucoma

Pressure-Sensing Contact Lenses To Monitor Glaucoma 

A new contact-lens prototype senses changes in pressure, which may one day provide continuous monitoring for patients with glaucoma.  Each lens (pictured) consists of a transparent polymer with tiny, opaque electrical circuits (gold).

A tiny electrical circuit built into contact lenses may provide 24-hour monitoring for glaucoma.  Currently, the only way for patients with glaucoma to keep tabs on the disease is to go to the doctor’s office. There, a clinician administers one of several tests to measure glaucoma’s main risk factor, intraocular pressure (IOP), and prescribes medication accordingly. But such visits normally occur two or three times a year, and there’s no take-home monitoring device for patients who may experience pressure spikes between visits.

Cornell Research Shows Evolution Of Milkweed Defense System

Genetic Analysis Shows Evolution Of Milkweed Defense System 

A monarch butterfly caterpillar gets ready to devour a milkweed leaf. 

The adage that your enemies know your weaknesses best is especially true in the case of plants and predators that have co-evolved: As the predators evolve new strategies for attack, plants counter with their own unique defenses.
