Researchers use 'trickery' to create immune response against melanoma

...chers "tricked" them into recognizing the tumor as dangerous as well. The alerted cells were then injected back into the mice where they successfully activated a particular T-cell response important for fighting tumors. That response, called Th1, led to a significant reduction in tumor growth in the mice. "Typ...

Social learning in noncolonial insects?

...the presence of others who have just experienced a dangerous environment, but they also continue to do so long after these "demonstrators" are gone. The authors showed that the long-lasting behavioral changes cannot be simply attributed to such nonsocial factors as long re-emergence times or residual odor cue...

Can anthrax be controlled?

... anthrax. What makes Bacillus anthracis especially dangerous is that these bacteria can form spores. The spores are extremely resistant against environmental stress and can survive for years.Infection with Bacillus anthracis can take place either via the lung or through the skin. Interestingly, the lung form o...

...corticoid production could alleviate some of these dangerous health effects." The laboratory findings were presented during a poster session Tuesday, Nov. 15, at the annual Society for Neuroscience meeting in Washington, D.C. Dr. Ulrich-Lai and a team of researchers from the department of psychiatry showed th...

Researchers uncover new genes that control longevity

...pact one of these genetic pathways, but it has the dangerous side effect of disabling the immune system. "We'd like to understand how aging occurs in yeast," Fields added, because "even though yeast is a simple, single-cell organism, it's still capable of revealing mechanisms in the aging process. Similar gene...

Plants have a double line of defence

...metabolic reactions often take place that would be dangerous for the organism at any place other than inside the compartments. If a fungus tries to invade a plant cell, the peroxisomes are led over to the entry site by the attached PEN2 protein. One or more sugar molecules can be separated from another cell co...

For that matter, this ability to detect species in earlier stages of development could benefit ecologists in their work as well, Meyer said. "Scientists studying butterflies are able to lin...

Four questions that may save your grandma's life: SNAQ screening tool predicts weight loss

Wilson says that most people who are elderly find their appetite isn't as robust as when they were younger. Their sense of taste and smell is blunted, and ...

Kidnapped: Colon cancer seizes hapless nerve growth protein

"L1's special abilities in helping nerve cells wire up through intercellular space are hijacked by aggressive tumors to sharpen their invasive edge. The L1 protein makes them better at moving around and penetrating the bod...

"Failure of this mechanism could result in chronic inflammatory skin conditions like lupus and psoriasis, said Shlomchik. "Thi...

How Rickettsial pathogens break into cells

There are two types of Rickettsial pathogens--the spotted fever group, which includes the Rickettsia conorii bacteria studied by Cossart and her colleagues, and the typhus group. Both must live inside cells to survive....

Tsunami + 1 year: Reviving exhausted fisheries should trump replacing boats, gear, experts say

"It would be a dangerous over-simplification, for example, to argue that with the death of such a high proportion of fishers, providing boats and gear to those that remain presents no risk to the sustainability of stocks or to the longer-term livelihoods of fishers."
