An artificial cornea is in sight, thanks to biomimetic hydrogels

...gineered into his artificial cornea the "homes" he built for cells that need to infiltrate the artificial lens and integrate it with surrounding natural tissue. "If you build it, they will come," Myung says. "The cells move in, and they bring furniture too--meaning the collagen they secrete. They even 'r...

Some butterflies travel farther, reproduce faster

...lar biologist, physiologist and chemist. The study built on the work of Hanski who has recorded changes in the butterfly population on the islands for years. It's in the genes The fritillary live in distinct patches -- rocky outcroppings containing plants that serve as food and provide a hospitable h...

Muscle and bone from an ink-jet printer

...ew level of complexity and control. The custom built ink-jet printer, which was developed at Carnegie Mellon, can deposit bio-inks in virtually any design, pattern, or concentration, laying down patterns on fibrin-coated slides placed in culture dishes containing MDSCs. Based on pattern, dose, or facto...

Neural networking nanotubes

...several micrometers in length. The researchers built up layers of their SWNTs to produce a film that is electrically conducting even at a thickness of just a few nanometers. They next grew neuron precursor cells on this film. These precursor cells successfully differentiated into highly branched neuron...

American scientist's research of life's first cells

...tionary experiment among 'proto-cells' -- vesicles built of membrane materials, some of which contained RNAs functioning as enzymes whereas others did not. Some were favored competitively, demonstrating greater evolutionary fitness." Chen describes how she has used simple "protocells" to study how life...

A new approach to growing heart muscle

...st. And once we understand how these models can be built in the lab, then we can work toward building a bioengineered heart." He notes that while many other labs focus on growing one heart component, only U-M is working on growing all the different heart components. Already, the U-M team has begun experi...

Discovery of the first resistance gene to rice yellow mottle virus

...owed the presence of the transgene . Viruses are built with a small genome coding for a limited number of proteins (5 in the RYMVs). They therefore need their host's proteins in order to accomplish each stage of their infection cycle. One of the proteins that the RYMV requires appears to be the eIF(iso)4...

Smashing the time it takes to repair our bones

...n bones. QUT recent graduate Dr Gwynne Hannay has built a gadget capable of promoting bone cell formation in the laboratory. Dr Hannay said his device replicated the mechanical and electrical stimulants which occurred naturally in the body to repair fractured and broken bones. "This device is about ...

With fruit fly sex, researchers find mind-body connection

...ks the notion that sexual mind and sexual body are built by separate sets of genes. Rather, researchers found, doublesex acts in concert with the gene "fruitless" to establish the wing-shaking come-ons and flirtatious flights that mark male and female fly courtship. Results are published in Nature Genet...

Breathing easy: When it comes to oxygen, a bug's life is full of it

...adox: how insects, which have a respiratory system built to provide quick access to a lot of oxygen, can survive for days without it. The insect respiratory system is so efficient that resting insects stop taking in air as they release carbon dioxide, according to research by Stefan K. Hetz of Humboldt Un...

Novel laboratory technique nudges genes into activity

... Drs. Corey’s and Janowski’s current results are built on previous work, published in 2005 in Nature Chemical Biology, in which they found that RNA strands could turn off gene expression at the chromosome level. The new UT Southwestern research, coupled with that from 2005, demonstrates a shift away ...

Light-based probe 'sees' early cancers in first tests on human tissue

...oratory tests on human tissue, a light-based probe built by researchers at Duke University's Pratt School of Engineering almost instantly detected the earliest signs of cancer in cells that line internal organs. If the preliminary success of the "optical biopsy" is confirmed through clinical trials, such ...

DNA layer reduces risk of reserve parts being rejected

... With this technique, ultra-thin DNA layers can be built up and immobilized. The first layer attaches to the surface by means of adsorption. The subsequent layers remain in place due to electrostatic interactions. This makes it possible to build up multiple layers with opposite charges. Step 1 positively c...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

... "The availability of a central repository that is built upon distributed information and data storage not only allows one to collect information more effectively, but also makes the data immediately available to researchers worldwide," said Kai Nan, director of CNIC’s Network Technology and Applications R...

Prehistoric mystery organism verified as giant fungus

...lso of the National Museum of Natural History. "He built up a convincing case based on the internal structure of the beast that it was a giant fungus, but agonized over the fact that he was never able to find a smoking gun in the form of reproductive structures that would convince the world that it was ind...
