Ritalin packs punch by elevating norepinephrine, suppressing nerve signal transmissions

...e to have a good idea of the drug's action when we put it all together." One broad question that intrigues researchers is whether ADHD traces back to the same area of the brain as attention deficit disorder, a similar condition but one in which hyperactivity isn't a symptom. They also want to know whet...

With cochlear implants, earlier use leads to better speech

...for or against cochlear implantation is frequently put off, Nicholas indicates. Hearing parents often find they need time to learn about deafness and potential treatments. Implantation also may be delayed to make certain an infant's deafness has not been misdiagnosed. Even when deafness is confirmed, t...

New device could cut chemotherapy deaths

... years and, if successful, the technology could be put into general use. The research team at Bath is co...ormulated as a bead, a fibre or mesh, or as a tube put into the body which leads outside the body and through which drugs can be fed. For the pre-clinical...

Value of services performed by insects tops $57 billion in US

...l part of a complex web of interactions that helps put food on our tables and remove our wastes. Humans - and probably most life on earth - would perish without insects, Vaughan said. Losey and Vaughan's study focused on the economic value of four particular services -wildlife nutrition, pest control, p...

Taking evolution's temperature: Researchers pinpoint the energy it takes to make a species

...oes have a price, and the price is very high." To put a number on it, it takes about 10 to the 23rd power - that is a 1 followed by 23 zeros - of energy units called joules to generate a new species of foraminifera plankton. "From a scientific perspective, we can now quantify biodiversity in terms of e...

Researchers win money to develop breath test to detect breast cancer

... breath and urine. "We realized that if one could put these molecules in a screening platform, they might develop a non-invasive, quick and inexpensive over-the-counter breast cancer screening test," Lahann said. ...

Northern birds are fatter!

...irds migrate north for the summer, the faster they put on weight", says Dr Williams (Simon Fraser University, Canada) who has been tracking migrating birds for several years. "This research may have implications for the designation of protected areas which will ensure birds can complete their spring and ...

Life, the remake

...in and again." Vermeij's view contrasts with that put forward by the late Stephen Jay Gould and others, who argued that the history of life is so dependent on improbable events and includes so many possible paths that the chances of repetition are vanishingly small. Vermeij argues that some innovations,...

Marrow-derived stem cells deliver new cytokine to kill brain tumor cells, offer protection

... from a patient, make them into neural stem cells, put in the gene of interest and treat the patient." In this case, the gene of interest produces IL-23, which appears to be very well suited for attacking gliomas. Earlier studies used IL-4, IL-12, and tumor necrosis factor related apoptosis inducing lig...

'Scent of a woman' tells male redback spiders to find a mate

...e. If they are lucky enough to find a female, they put all of their resources -- including their life -- into it. In the process, they deposit a sperm plug -- a small part of their copulatory organ that stays inside the female -- that prevents any future males from successfully fertilizing her eggs, mean...

AIDS-related cognitive impairment exists in two separate forms

...odriguez said, and up to 96 different tests can be put on a single tray. "Having batches of samples together in a single assay that can then be read automatically makes it easy for routine clinical use," she said. "The test has a lot of potential, but needs to be further studied and validated." Methyla...

UCR researchers design chip that can improve citrus varieties

...hat happens at the cellular level when oranges are put in cold storage after they are harvested, leading eventually to better methods of storage that improve fruit flavor." Manufactured by Affymetrix, Inc., the GeneChip® Citrus Genome Array is made up of a glass wafer on to which nearly one million dif...

Study fishes out new role for prostaglandins

...acular," said Solnica-Krezel, "is that…if you just put some prostaglandin back in the culture medium, you rescue the phenotype." In another set of embryos, the researchers blocked prostaglandin receptors, EP2 and EP4. Blocking the EP4 receptor caused defects similar to those associated with blocking PG...

Unraveling the viral mechanism

..., in some ways," said Chiu. "You extend it. If you put it away in a heap, then you have trouble using it again. But if you coil the hose orderly, then it is easy to use again. I think the virus does the same thing. The virus genome has to enter the capsid during the birth of the virus and then inject int...

ASU researchers find link between social behavior, maternal traits in bees

...avior was tied to reproductive traits. Amdam then put her results to a crucial test -- wild-type bees (bees that had not been used in the experiment) were captured after their first foraging flight. Amdam and her team recorded what the bees brought back from the forage and measured their ovaries. Resu...

Gene variation increases SIDS risk in African Americans

... prevalence of SIDS in half by teaching parents to put babies to sleep lying on their backs. The campaign was based, in part, on the assumption that babies sleeping on their bellies had more spells of interrupted breathing or apnea. One of the immediate consequences of apnea is a slight increase in aci...

...y inject it into the animals, recover it, and then put into a second mouse. This is repeated at least five times. Five generations, Dr. Dietzschold explains, is usually enough to see whether the virus will either mutate and turn dangerous, or show genetic stability. The research team has tested the curr...
