Better beetle sought for salt cedar control

... later as a beetle. "Almost immediately they will start mating and will live for about 30days," she said. ...lifetime." Damage is what the researchers want to start seeing, Carney said. ThePosidi beetles at Lake Meredith defoliate small branches, but the damagehasn...

Malaria, potato famine pathogen share surprising trait

...ish potato famine use identical protein signals to start an infection. "I don't think anyone expected this...s, nor is it likely that the malaria parasite will start infecting plants. However, he said it's feasible to think that one day researchers could develop a ...

A more powerful and efficient engine for rice: the C3-C4 challenge

...urgent rice production challenges we face, we must start now on this work--there's no time to lose," Dr. Sheehy said. ...

How can identical twins be genetically different?

...dy. The advantage of studying twins is that they start out with the exact same genetic information. Therefore, differences in gene expression are attributable to different environmental factors rather than genetics. Such factors could cause a random genetic mutation or affects how DNA is packaged. "The...

New lab technique churns out fungus' potential cancer fighter

...earchers finally produce enough rasfonin to really start investigating how it functions, and how we might harness it to fight cancer." In 2000, researchers from Chiba University in Japan and the University of Tokyo simultaneously discovered a compound in certain fungi that selectively destroyed cells depe...

Device effective in zapping the pain out of migraines

...It was previously believed that migraine headaches start with vascular constriction, which results in an aura, followed by vascular dilation that will lead to a throbbing headache. However, in the late 1990s it was instead suggested that neuronal electrical hyper excitability resulted in a throbbing headac...

Genetic tug of war determines sexual differentiation

..." she continued. "Once the testes are formed, they start producing testosterone, which commits the whole animal to male development. The researchers found that not only does Fgf9 stabilize the expression of Sox9 and secure the male fate of the gonad, it suppresses the activity of the ovary-promoting gene ...

Stanford doctors advance in bid to turn mice stem cells into blood vessels

...ontracting, you really know they're alive, and you start to believe this stem cell stuff has possibilities." For the study, Abilez received first place in the seventh annual International Society of Endovascular Fellows' research award in laboratory sciences. The findings are published in this month's edi...

Survivors of childhood polio do well decades later as they age

...rs. The average age of participants at the study's start was 53, and the patients were an average of 40 years past their childhood experience with polio. The researchers measured strength and loss of neurons at the beginning of this period, and then again five and 15 years later with electrophysiological t...

The vicious cycle of rainforest destruction

...ive areas. The researchers think we may be at the start of a vicious cycle, where global warming causes the rainforests to shrink, so increasing the amount of carbon in the atmosphere, raising the earth's temperature and magnifying the impact on the rainforests. Heading the work at Leeds is Professor of ...

Tiny airborne particles are a major cause of climate change

Protein connections: A network to understand disease

...s applicable to any human disease," she said. "You start with a handful of genes you know cause disease and then go find their partners, and then their partners and then build a network that will include all the factors that make you susceptible to a disease or cause the symptoms of it." "Instead of think...

Protein-coated dental implants could improve bone regeneration

...ated with the proteins, which Dr. Wikesjö hopes to start this summer. "There are still things we need to learn. In some cases, the protein may rapidly release from the implant, and other times, there appears to be a more gradual release," Dr. Wikesjö says. "We need to find out what factors cause that. I...

Discovery of agile molecular motors could aid in treating motor neuron diseases

... how it all works in a living cell. In the lab, we start with a clean microtubule with a motor walking across it, but in the cell it's different: microtubules are packed together, with proteins studded along them, and cellular organelles and mitochondria are crammed in. The motor needs to maneuver around t...

Finding paves way for better treatment of autoimmune disease

Dr. Iwashima has an Alcoholic Beverage Medical Research Foundation grant to pursue alcohol's potential for helping isolate desi...

Today's babies are fatter babies

... results show that efforts to prevent obesity must start at the earliest stages of human development, even before birth," says Gillman. "These efforts should include avoiding smoking and excessive weight gain during pregnancy, preventing gestational diabetes, and promoting breastfeeding, all of which resea...

What's nature worth? New computer models tell all

For example, if a town council is trying decide the value of a wetland--compared to, say, building a shopping mall there--these models will help them put a dollar value on it. If a country wants to emulate Costa Rica's program of...
