Why do aneurysms form? New studies suggest leading role for white blood cells

...mes that are capable of doing that eating. But the question of how those enzymes get there, and what prompts them to arrive, has been unanswered. "Neutrophils are known to carry some of these enzymes, called matrix metalloproteinases and chemokines, which help them attack invaders," says Upchurch. "We wanted...

Insight into our sight: A new view on the evolution of the eye lens

...ertebrate evolution, and it raises a long-standing question in evolutionary biology: How could a complex organ...r new work, Shimeld and colleagues approached this question by examining the evolutionary origin of one crystallin protein family, known as the ?-crystallins. F...

AACR Favors 'full spectrum of stem cell research biology'

...ciated with scientific advancements that the first question on everyone's mind was, 'why wasn't this huge medical breakthrough made by Americans?' "Sadly," he continued, "American stem cell biology suffers from a small and unsteady flow of graduate students, post-doctoral fellows and early-career faculty. No...

Naturally occurring asbestos linked to lung cancer

...searchers. The study - the largest to examine the question - will be published this fall in the American Journal of Respiratory and Critical Care Medicine. Exposure to asbestos in the workplace, particularly in shipyards, has long been recognized as a risk factor for mesothelioma, a rare form of cancer affe...

Modification of program enables prediction of gene transcription

...convert a blind guessing game to a multiple choice question ?is it a UTR exon or a protein-coding exon? These kinds of questions are easier to answer now." ...

The very defensive caterpillar

Muscle repair: Making a good system better, faster; implications for aging, disease

...amage, which may limit the repair process. "So the question is," Koh continued, "if PAI-1 limits recovery, why does it increase after injury? It may be that PAI-1 is a multifunctional molecule and does some things that we haven't yet identified and measured." Indeed the paper says that "in addition to influen...

Living with salt

...f Weizmann Institute scientists have addressed the question of how molecules essential to life, such as proteins, have adapted to function in extreme environments. The proteins they investigated were isolated from halophilic (salt-loving) microorganisms from the Dead Sea. After determining the 3-D structures ...

'Underground' tunnels discovered as means for communication between immune system cells

...ar signals to other immune system cells calls into question the long-held belief that immune system cells talk to one another solely by secreting substances such as cytokines, the authors say. It now seems clear that intercellular communication is much more complicated. While it would be fascinating to see th...

Neanderthal teeth grew no faster than comparable modern humans'

Protein structure key for AIDS, cell function

...ron Source (CHESS). "So this is a very fundamental question for biologists." It turns out that CD38 helps produce at least two calcium messenger molecules, each of which then opens channels for the release of calcium from specific stores, or reservoirs, within cell organelles. High intensity X-rays made it...

Mosquito study shows new, faster way West Nile can spread

...87 recipient mosquitoes. The discovery calls into question the current conception of mosquito transmission of West Nile virus and possibly other viruses such as the one that causes dengue fever. According to that theory, many vertebrates were considered to be "dead-end hosts" that did not pass along the viru...

Monkeys understand numbers across senses

... different sets from different modalities. And the question has been whether an animal without that kind of language based representation can still notice or represent these commonalities." According to Jordan, their research team is planning future studies that will use the same experimental design to explo...

Results of world's first gene therapy trial for arthritis show approach safe, feasible

...r patients to five years so that there'd be little question about long-term safety," explained Christopher H. Evans, Ph.D., D.Sc., the study's lead author, now director of the Center for Molecular Orthopaedics at Brigham and Women's Hospital and Robert Lovett Professor of Orthopaedic Surgery at Harvard Medica...

Vibrio bacteria could be a risk to fish as well as humans

...fessor Austin comments: "Having observed this, the question arose about whether any of these new species could have implications to the health of marine animals. The answer was that around half of the new species killed fish in laboratory conditions. Our research shows that marine vibrios could cause disease ...

Forsyth scientists find three bacteria associated with oral cancer

...e often-fatal disease. The findings also open the question of whether bacteria might, in some way, play a causal role. The current discovery, reported in the July 7 Journal of Translational Medicine, suggests that elevated levels of three particular bacteria in saliva indicate the presence of oral squamous ...
