MIT crafts bacteria-resistant films

CAMBRIDGE, Mass.--Having found that whether bacteria stick to surfaces depends partly on how stiff those surfaces are, MIT engineers have created ultrathin films made of polymers that could be applied to medical devices and other surfaces to control microbe accumulation.

Bacteria-resistant Films Created: Microbe Adhesion Depends On Surface Stiffness

Ultrathin Films Resist Bacteria

CAMBRIDGE, Mass., May 16, 2008 --Inexpensive, easy-to-produce, ultrathin films made of polymers could be applied to medical devices and other surfaces to control microbe accumulation. They could also help reduce the spread of hospital-acquired infections, which take the lives of 100,000 people and cost the US an estimated $4.5 billion annually, said researchers at MIT who developed the films.

MIT sues Affymetrix for patent infringement

Affymetrix, the Santa Clara maker of tools used to study DNA and diagnose diseases, was sued for patent infringement by the Massachusetts Institute of Technology over the company's GeneChip system used to analyze genes. Affymetrix has knowingly infringed the patent, MIT and a company started by an MIT professor said in a federal court complaint filed Tuesday in Boston. Affymetrix filed an application with the U.S. Patent and Trademark Office in September 2004, six months after a similar patent was approved for MIT, the university said in its complaint. The patent regulators ruled in May 2007 that the MIT group was the first inventor, according to the complaint. The GeneChip technology is used to develop new therapeutic drugs and to investigate the cause of cancer, AIDS and other diseases, Affymetrix has said.

Eugenic Euphoria: Texas A&M profs find body's bacteria talk to each other

Single-celled bacteria are some of the simplest living organisms, but Texas A&M researchers have discovered that bacteria have 'conversations' with each other using chemical signals. Chemical engineering professor Thomas K. Wood said that by better understanding bacteria's signals we can control the way that bacteria behave.

CAMBRIDGE, Mass. -- MIT researchers have figured out how bacteria ensure that they respond correctly to hundreds of incoming signals from their environment.

Man-made 'defensin' rips resistant bacteria apart

A mimic of the potent proteins used by white blood cells to punch holes in bacteria is to begin clinical trials in Canada. It could be a valuable new weapon against the growing threat of antibiotic-resistant "superbugs".

Bacteria Found Alive In Ice 120,000 Years Old

FiReaNGeL notes research presented this morning at Penn State on the discovery of a new, ultra-small species of bacteria that has survived for more than 120,000 years within the ice of a Greenland glacier at a depth of nearly two miles. From the psu.edu announcement: "The microorganism's ability to persist in this low-temperature, high-pressure, reduced-oxygen, and nutrient-poor habitat makes it particularly useful for studying how life, in general, can survive in a variety of extreme environments on Earth and possibly elsewhere in the solar system. This new species is among the ubiquitous, yet mysterious, ultra-small bacteria, which are so tiny that they are able to pass through microbiological filters. Called Chryseobacterium greenlandensis, the species is related genetically to certain bacteria found in fish, marine mud, and the roots

Hey, Bacteria: Pipe Down, Will You?

Duke's Claudia Gunsch is working on a way to silence genes in bacteria using short, singled-stranded DNA, says MIT's Technology Review. If she can get it to work -- she recently presented a proof-of-concept study at the American Society for Microbiology -- there are a variety of applications, including engineering better biofuels, turning off bacterial antibiotic-resistance genes, and filtering bacteria in water.

Newly identified enzyme treats deadly bacterial infections in mice

By the time antibiotics made their clinical debut 70 years ago, bacteria had long evolved strategies to shield themselves. For billions of years, bacteria hurled toxic molecules at each other in the struggle to prosper, and those that withstood the chemical onslaught marched on. Now, with an uptick in antibiotic-resistant bacteria reaching alarming proportions, Rockefeller University scientists have identified an enzyme produced in viruses (called bacteriophages) that could stop these one-celled powerhouses dead in their tracks.

MIT Helps Third World With Hands-On Approach

Hugh Pickens writes "About 60 people from 20 nations will descend on the MIT campus July 14th for the second annual International Development Design Summit to begin an intensive month-long process of creating technological solutions for the needs of people in the world's developing nations. The goal of the program is to develop simple, inexpensive devices that in some cases can be produced locally and make a real difference for people and communities. The event is the brainchild of MIT Senior Lecturer Amy Smith, a returned Peace Corps volunteer and a past winner of the MacArthur 'genius' grant. Previous products of Smith's design class include a bike-powered corn sheller, a metal press that can make clean-burning fuel out of agricultural waste, and an electricity-free incubator.

Bacteria Play Vital Role in Human Health

The crook of your elbow is not just a plain patch of skin. It is a piece of coveted real estate, a special ecosystem, a bountiful home to no fewer than six tribes of bacteria. Even after you have washed the skin clean, there are still 1 million bacteria in every square centimeter.

Factors That Make Bacteria More Modular Detailed

Many bacteria break their metabolic processes into chunks. That may be logically tidy, but it's often metabolically inefficient. Researchers have now figured out the factors that tend to make bacteria more modular.
