FDA sees nanotech challenges in every product category it regulates

...ning. But the agency must act rapidly to adopt and fully implement the Nanotechnology Task Force’s recommendations. Without moving quickly and building on the recommendations in the Task Force report, FDA will not be able to keep pace with today’s rapidly developing nanotechnology market or engender consum...

Brain inflammation may be friend, not foe, for Alzheimer's patients

...tem is tremendous and is an area that has not been fully explored,” said O’Banion. “That said, people have to remember that the current findings are in mice, not people. We need to be cautious about how to interpret the results.” ...

A new plant-bacterial symbiotic mechanism promising for crop applications

...of the signal molecule itself, which remains to be fully determined, brings a glimpse of future agricultural applications. Many plants live in symbiosis with bacteria, but the mechanisms are known for only a small number of these interactions. The demonstration of alternative pathways capable of trigge...

Millions of children denied drug that costs less than $3 a year

...nt epilepsy management programme will work only if fully integrated within a community healthcare delivery system, which should provide not only reliable supplies of drugs, with adequate facilities for storage and dispensing, but also educational programmes for health practitioners and the general populati...

Researchers shed light on shrinking of chromosomes

.... “Sometimes chromosomes get stuck and cannot be fully separated by the spindle that normally distributes them into the daughter cells,” says Felipe Mora-Bermúdez, who carried out the experiments in Ellenberg’s lab, “we think that the ‘super condensation’ at later stages helps to disentangle such chromos...

New findings challenge established views on human genome

...for proteins, interact in overlapping ways not yet fully understood. In a group paper published in the June 14 issue of Nature and in 28 companion papers published in the June issue of Genome Research, the ENCyclopedia Of DNA Elements (ENCODE) consortium, which is organized by the National Human Genome Re...

Researchers demonstrate way to control tree height

... cells – when they are inhibited, the cells do not fully elongate, and plants remain short and stocky. “It’s really interesting that these genes from Arabidopsis, which is a small plant in the mustard family, have been conserved through 50-100 million years of evolution and can perform more or less the ...

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

...ipulations of this sort are complicated and do not fully meet the researchers’ needs. Prof. Mordechai “Moti” Liscovitch and graduate student Oran Erster of the Weizmann Institute’s Biological Regulation Department, together with Dr. Miri Eisenstein of Chemical Research Support, have recently developed a u...

Experts predict Tamiflu could halve the pandemic influenza death toll versus no intervention

...break, especially as it is unlikely that a vaccine fully matched to the strain will be available in the ini...ning of a pandemic, supplies of vaccines which are fully matched to the pandemic strain will be limited or non-existent. This is because vaccine production c...

Arctic ice retreating more quickly than computer models project

...resent-day sea ice and the models may also fail to fully capture changes in atmospheric and oceanic circulation that transport heat to polar regions. March ice Although the loss of ice for March is far less dramatic than the September loss, the models underestimate it by a wide margin as well. The s...

Resistant HIV quickly hides in infants' cells

...erapies. As Persaud remarked, "It is important to fully understand the extent to which the persistent drug-resistant virus affects whether those drugs can be reused within the child’s lifetime.?This is a critical question and an area of intense investigation, especially in light of the high rates of antir...

How to steer a moving cell

...c to begin migrating. The researchers hope to fully define the protein components of the compass to gain a better understanding of what directs cell migration or, in the case of cancer cells and inflammation, cause cells to migrate where they normally wouldn’t. "The ability to spatially organize s...

Left-right wiring determined by neural communication in the embryonic worm

...dedness, AWC asymmetry arises before the animal is fully developed, maybe they needed to examine the nervous system of the embryonic worm. Using an electron microscope, they discovered that the developing worm's neural network, which had not previously been mapped, was completely different from that of the...

Improved predictions of warming-induced extinctions sought

...The authors acknowledge, however, that they do not fully understand why so many species persisted during these ice ages, and caution that some genetic research suggests that species might in fact be more vulnerable than the fossil record indicates. ...

Genetic fingerprints identify brain tumors' origins

... as a necessary approach," Gutmann says. "We won't fully understand the causes of pediatric brain tumors until we consider them in the context of factors that shape the development and specialization of different brain regions." ...

30+ AIDS vaccine clinical trials in 24 countries, research occurring on every continent

...outh Africa, Uganda and Zambia trial sites are now fully enrolled with data expected later this year. Two of the most advanced trials underway in 2007 are from Sanofi-Pasteur and Merck & Co., Inc. Data from Merck's ongoing Phase IIb test-of-concept trial with its adeno-5 vector vaccine candidate...

Study suggests some drug resistance to influenza B medications

In a paper published in the prestigious Journal of Biological Chemistry in April, Professor Bryan Williams, Director of the Monash Institute of Medical Research, led a collaborative study that investigated the effects of salicylates on ...

Major gene study uncovers secrets of leukemia
