Cells re-energize to come back from the brink of death

...an also foil a backup self-destruct program, which allows them to survive and become cancerous. The St. Jude study also suggests that a drug that disrupts a cancer cell’s ability to block this backup program would allow that program to kill the cell. Such a specifically targeted drug might be more effec...

Discovery in orange cauliflower may lead to more nutritious crops

...scribed in the December issue of The Plant Cell -- allows the vegetable to hold more beta-carotene, which causes the orange color and is a precursor to the essential nutrient vitamin A. While cauliflower and many staple crops have the ability to synthesize beta-carotene, they are limited partially because t...

Research team identifies new Alzheimer's gene

...developing Alzheimer’s disease. “This discovery allows us to accelerate the development process for creating a new diagnostic test that is capable of detecting the presence of GAB2, and may ultimately help millions of individuals reach a more informed decision regarding the most appropriate type and timi...

Columbine flowers develop long nectar spurs in response to pollinators

...s leading to plants' nectar--happens in a way that allows flowers to match the tongue lengths of the pollinators that drink their nectar, biologists have found. The researchers were Justen Whittall of the University of California at Davis and Scott Hodges of the University of California at Santa Barbara. T...

Brightening prospects of using fluorescent nanotubes in medical applications

... where skin and other tissue is transparent – that allows the nanotube light to stand out. Nanotubes are made entirely from graphitic carbon, which is non-toxic and, at least so far, experiments that have been done indicate that they do not damage living cells. By comparison, quantum dots, which are a p...

Dual-imaging technique useful before -- and during -- brain surgery

... our preliminary data is very promising because it allows us to optimize surgical approaches to treating brain tumors to ultimately improve patient outcomes.” He says that combining standard visual, sound, and voice-based tests, whose results are measured by MRI, performed on a high-field-strength (3 Te...

Researchers shed light on shrinking of chromosomes

...sion. Condensation, the shortening of chromosomes, allows the cell to handle such huge amounts of genetic material during cell division and helps preventing fatal defects in chromosome separation. Now researchers from the European Molecular Biology Laboratory (EMBL) for the first time tracked chromosome con...

Plants recognize their siblings, biologists discover

...et competitive and start growing more roots, which allows them to grab water and mineral nutrients before their neighbours get them. It appears, though, that they only do this when sharing a pot with unrelated plants; when they share a pot with family they don’t increase their root growth. Because differenc...

Plastic that grows on trees

...ces. The hydrogen-hydroxyl position-switch that allows the catalytic conversion was verified by nuclear magnetic resonance performed at the William R. Wiley Environmental Molecular Sciences Laboratory, a DOE national scientific user facility located at PNNL. During the swap, the molecule opens, Zhang sai...

Mutating the entire genome

...leting non-gene DNA sequences, and this new method allows us to evaluate what these sequences do,” says Mario Capecchi, distinguished professor and co-chair of human genetics at the University of Utah and an investigator for the Howard Hughes Medical Institute (HHMI). The new method “is significant beca...

Weizmann Institute scientists develop a general 'control switch' for protein activity

...rtant advantage compared with other techniques: It allows the total and precise control over the activity of an engineered protein. Such activity can be brought to a desired level or returned to its natural level, at specific locations in the body and at specific times – all this by giving exact and well-ti...

Fat fish put obesity on the hook

...to model human disorders like obesity in zebrafish allows scientists to understand the molecular basis of disease. This may ultimately increase the efficiency and power of the drug discovery process, thus bringing new medicines to the market faster and cheaper.” In the study, researchers caused obesity ...

Electric fish conduct electric duets in aquatic courtship

...the electrical and motor patterns during courtship allows for further exploration of such topics as mate choice and neural basis of pattern generation in these fish," explained Hopkins, noting that the next step in the research will be to decode the fish transmissions and unravel their meaning....

Adult stem cells from human cord umbilical cord blood successfully engineered to make insulin

...lar masses that produce the hormone insulin, which allows the body to utilize sugar, synthesize proteins and store neutral fats, or lipids. "But we’re a long way from that," Denner warned. Denner said this research, which reflects a fruitful collaboration with co-authors Drs. Colin McGuckin and Nico For...

'Smart' mice teach scientists about learning process, brain disorders

...ecently developed and called conditional knockout, allows much more sophisticated experiments than traditional knockout, which entirely eliminates the gene. "Being able to turn a gene off throughout a brain is a really advanced thing to do," Dr. Bibb said. "It’s been shown that it can be done, but we put...

Avian influenza survivors' antibodies effective at neutralising H5N1 strain

...zerland. The researchers used a new technique that allows them to rapidly reproduce human monoclonal antibodies starting from a small sample of blood. "We can't say for certain that a pandemic influenza virus will resemble the H5N1 strain that we have been studying or that the monoclonal antibodies gener...

Focused ultrasound relieves fibroid symptoms in women

...onance-guided, focused ultrasound surgery (MRgFUS) allows radiologists to precisely target fibroids without ...roids with an optimized, less restrictive protocol allows for treatment of a greater fibroid volume, which results in even greater symptomatic relief at clini...

HIV and malaria combine to adversely affect pregnant women and their infants

...PAM is mediated by a special type of antibody that allows women to preferentially clear the parasites in their placentas. They found that HIV-infected women lose these antibodies and again become susceptible to the ravages of PAM. The findings, according to Kain, may help in the development of PAM vaccin...

Resistant HIV quickly hides in infants' cells

...in these infants, you avoid applying pressure that allows drug-resistant HIV to flourish." The study concluded that it is important to consider drug-resistance testing as a part of the initial evaluation of newly HIV-infected infants so that appropriate choices can be made when considering possible treat...

Puzzling plankton yield secrets to role in evolution/global photosynthesis

...ins that surfaced in their analysis, which he said allows the organisms to horde nutrients and reduced their appetite for iron—an adaptive process in Ostreococcus. "This work builds on the community’s emerging understanding about how carbon fixation is carried out by picoplankton," said Brian Palenik, le...
