Biologists call for better choice of model organisms in 'evo-devo'

...lar the big six, have been chosen because they are easy to keep in the laboratory, select and breed. "Whilst this is generally fine in the context of development research, the benefits to evo-devo as a subject are limited. "There are upwards of 35 phyla of animals, and four of our six best models c...

Protein averts cell suicide but might contribute to cancer

...earch comes from a microorganism. It is relatively easy to produce in large quantities and to study, and it is similar to one of the four such enzymes found in humans. For this research, Fiala developed a new way to sequence very short lengths of DNA. "This allowed us to pin down exactly what mistakes...

Human preference for other species could determine whether they survive

...d that a species' popularity wasn't because it was easy to get to, or because it had the largest population, or because of similar factors. "I went to great lengths to ensure that what I was looking at was a purposeful set of pictures and not one just based on logistics," he said. The popularity ranki...

One-of-a-kind imaging probe reveals secrets useful for drug discovery

...enough secretions to do analyses and, no, it's not easy to do," Meinwald said. "When we started you could hardly work with natural materials in terms of milligrams. Now you can do chemistry on the microgram scale. NMR has made enormous progress - it has thousands of times the sensitivity it used to have. ...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

...s of infected individuals. 'Protecting virus' is easy to administer as it targets the same cells as any other flu virus and uses the same method to enter the cell. Laboratory work to date has used a drop of saline containing the protecting virus, squirted up the nose. Aerosol administration, used alrea...

Sequencing of the oyster mushroom genome

...that lignin has a chemical composition that is not easy to break down ?similar to some of the contaminant compounds that man releases into the environment, such as certain colorants or oils and by-products of the timber industry such as pulp and paper. Thus, the study of the functioning of the oyster mu...

New research identifies gene important for nicotine's effects on the brain

...king cessation therapies. However, it will not be easy to target the signaling molecules manipulated in this study in human smokers. "They are not just in nerve cells involved in addictive behavior; these signaling molecules are important throughout the brain and body", says Picciotto. "The more we und...

The power of one: A simpler, cheaper method for cell fusion

It's not easy to make one plus one equal one. But biological engineer Chang Lu has done just that with a new and cheaper method to electrically fuse cells - a vital technology for studying stem cells, creating clones and finding disease antibodies. "The only cu...

'Failed' experiment yields a biocontrol agent that doesn't trigger antibiotic resistance

...ul tools for genetic engineering. It is relatively easy for a scientist to alter a plasmid's genetic makeup and then transfer the plasmid into a bacterium. The host bacterium then replicates the recombinant plasmid and transfers copies of it to other bacteria in a process called conjugation. As he inve...

BC catalyst discovery promises faster, cheaper drug production

... than many other catalysts. "The new catalyst is easy to prepare, requires little or no solvent and therefore minimizes waste, and can be used in air and can be recycled several times," Prof. Snapper added. "Together, these properties make our discovery an important one both from the theoretical as well...

American scientist's research of life's first cells

...ological organization might have been surprisingly easy during the origin of life." Born in San Diego, California, to Taiwanese-American parents, Chen majored in chemistry at Harvard University, and as an undergraduate studied molecular recognition in the laboratory of Gregory Verdine. She then entered...

Sea urchin genome suprisingly similar to man and may hold key to cures

... to the use of mice. Raising sea urchin embryos is easy and inexpensive. One female can provide up to 20 millions eggs. The embryos develop in just three days and are transparent. Also, single cells can be easily observed live in the embryos. "If we know how these biological processes work, then we ca...

Taking 'chips' to the next level of gene hunting

...rrespond to the top layer. Says Boeke, "It's so easy to differentiate the top and bottom layers. Next we're going to try adding another layer reading diagonally" to triple the amount of genomic information packed onto the tiny chips. ...

Biodegradable napkin -- featuring sensitive nanofibers -- may quickly detect biohazards

...ther commonly contaminated places could soon be as easy as wiping a napkin or paper towel across a surface, says a researcher from Cornell University. "It's very inexpensive, it wouldn't require that someone be highly trained to use it, and it could be activated for whatever you want to find," said Marga...

Replacing insulin is top-ranked breakthrough foreseen for health in developing world

...entre for Molecular Medicine. "While there are no easy solutions to the complex challenges facing developing countries, these technologies offer real promise in the field of health. It is a young field and there's great opportunity to shape it now while it is developing." says Heather Greenwood of the C...

Scientists find mutations that let bird flu adapt to humans

...hem to recognize human receptor molecules and gain easy access to cells, typically in the human respiratory system. The change is thought to occur when human patients are exposed at the same time to a human flu virus and an avian flu virus. Most viruses, including influenza, readily swap genes with one ...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

...out this fabrication methodology is that it's very easy to implement, it's very cheap and it's very reproducible." Tripp said the technique is so powerful that it has the potential to detect a single virus particle and can also discern virus subtypes and those with mutations such as gene insertions and...

New tool helps blood specialists improve patient care

...e improvement plan. The Self-Directed PIM makes it easy to enter the data, design the improvement plan, and report to ABIM on the changes made to the practice. "We commend ASH for their leadership in identifying these performance measures to improve the quality of care hematologists provide to their pat...

A fisheye view of the deadliest breast cancer

...aboratory model organism. The zebrafish is tough, easy to breed, and a vertebrate, just like us. Being immune suppressed, the transgenic fish allowed Konstantin Stoletov and colleagues at UCSD to insert a xenograft of human MDA breast cancer cells. Being transparent, the zebrafish’s tissues gave them a ...

For crickets, parasitic flies can stop the music

...s, by contrast, actually mount the males, so it is easy to know what they are choosing. Also, she said, the complete absence of parasitic flies in spring allows the researchers to examine the role of flies as a selective pressure on male singing and female mate choice behavior. That said, not all of th...
