What does the public really know about HPV?

...at they were "very likely" or "somewhat likely" to want the vaccine for their daughter if it were provided at little or no cost, compared to 38 percent of parents who would consider the vaccine for their daughter if it would cost their family. ...

Mayo researchers discover HIV dependence on a human protein

...ntegrate," says Dr. Poeschla. "Future studies will want to factor such potential potency into designs of screens for additional key cellular proteins that HIV either appropriates as partners, as in the case of p75, or schemes to evade. Quite a few more likely exist. The challenge is to use the right metho...

Drug can quickly mobilize an army of cells to repair injury

... drug already has FDA approval for medical use. We want to find out if this treatment will lead to long-lasting improvement in blood flow, heal ulcers, relieve pain and prevent amputations." ...

Study highlights new and cheaper way to treat heroin addiction

... controlled and tailored to the individual. "We want to engage young people in a treatment programme which stops them from injecting drugs and running the risk of infection," he said. "Apart from the danger of contracting AIDS, drug users run the real risk of exposure to the potentially fatal liver...

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

...use it, and it could be activated for whatever you want to find," said Margaret Frey, the Lois and Mel Tukman Assistant Professor of Fiber Science and Apparel Design at Cornell. "So if you're working in a meat-packing plant, for instance, you could swipe it across some hamburger and quickly and easily det...

Some butterflies travel farther, reproduce faster

...n its naturally fragmented environment. Scientists want to know how this fragmentation influences a species' evolution. "We may be selecting for genes that enhance the dispersal or migratory capability of animals when we fragment the landscape," Fescemyer said. The animals best able to migrate are more ...

Engineer ramps up protein production, develops versatile viral spheres

Squid-inspired design could mean better handling of underwater vehicles

...s' actual maneuvering capabilities. "We didn't want to treat the symptom alone," he said. "We made it our goal to resolve a widespread problem." Mohseni created his new generators after studying the formation of vortex rings, much like those formed by squid and jellyfish to move themselves underwa...

Does missing gene point to nocturnal existence for early mammals?

...no need for the second gene, for instance. We also want to find out what losing one of these genes means for humans."...

Chemical tests of cell growth enter third dimension

...s a device to monitor a drug's effect, whether you want to stimulate or inhibit cell growth," Yang said. "We have used it on colon cancer cells and mouse embryonic stem cells. And in both cases, we found a very good relation between cell growth and fluorescence intensity." The device can be used with sta...

Slow brain waves play key role in coordinating complex activity

...another task," said UCSF's Kirsch. "On the fly you want to link these areas to do a task, and when the task is over, you want to decouple them and let them link up with someone else. Ryan has shown that the theta waves allow t...

Does natural selection drive the evolution of cancer?

...on in the tumor. So let's think about how we might want to influence that evolution. Can we push it down paths that might be more beneficial to us?" One idea might be to develop new drugs that would act as benign cell boosters. Such drugs would specifically target the more benign cells in a tumor to in...

Emergency contraception fails to halt abortions

... does help some women some of the time, who do not want to get pregnant. Use of this form of contraception has increased in the UK in recent years and whereas 1% of women requesting an abortion in 1984 said they had used it to try and prevent the pregnancy, 6% of women had done so in 1996 and 12% in 200...

UVa researchers seek to unlock broccoli's cancer fighting secret

... lessen the occurrence of some types of cancer. We want to know how these compounds work and what their specific targets may be," says Janet V. Cross, Ph.D., Assistant Professor of Pathology at the University of Virginia School of Medicine. Cross and her colleague Dennis J. Templeton, M.D., Ph.D., chair...

Fighting like a girl or boy determined by gene in fruit flies

...o developed the fruit fly fighting model used. "We want to understand that. I can't think of a better system to study than fruit flies. And no one gets hurt." The fruitless gene is known for its role in male courtship. The large gene makes a set of male-specific proteins found exclusively in the nervou...

Researchers barcode DNA of Venice museum's vast fungi collection

...ho study species distribution. For example, if you want to figure out how some species are related to one another, and you know something about their taxonomy, you can go back to their DNA to see if the morphological characteristics match their molecular code." Without the DNA fingerprint, researchers ...

Paramecia adapt their swimming to changing gravitational force

...dove for where the sediments ought to be. "If you want to make something float more," said Valles, "you put it in a fluid and you pull the fluid down harder than you pull the thing down. And that's what we basically do with the magnet. That causes the cell to float more ?and that turns gravity upside dow...

Study: Living coral reefs provide better protection from tsunami waves

...c idea of what variables are important, but if you want to quantify the effectiveness of a barrier reef around a particular island, you'd want to model that island directly," Kunkel said. ...

Study finds the air rich with bacteria

...imate change affects bacterial populations. "We want to determine the background levels of airborne pathogens and other microbes because only very limited work has been conducted on cataloging organisms in the air," says Andersen. "This work underscores how much we don't know about airborne bacterial p...

Fatty fish protects against cancer

If you want to avoid cancer of the kidneys, a new major study from Karolinska Institutet in Sweden shows that eating salmon or other kinds of fatty fish a few times a month would be one good way to go about it. At the end of the 1980s, 90,000 Swedish women were...
