Defenseless plants arm themselves with metals

A group of plants that uses metal to defend against infection may do so because the normal defense mechanism used by most other plants is blocked. Purdue University researchers found that this group of plants produces, but does not respond to, the molecule that triggers the infection response used by nearly all other plants. The molecule does, however, allow this group of plants, called m...

Molecular messengers perform a crucial role in the ability of injured nerve cells to heal themselves

Weizmann Institute findings might advance search for new therapies for injured nerve fibers. Long distance messengers star in many heroic tales, perhaps the most famous being the one about the runner who carried the news about the victory of the Greeks over the Persians in the fateful battle of Marathon. A team of researchers at the Weizmann Institute of Science has now discovered how molecular m...

Tiny polyps gorge themselves to survive coral bleaching

Certain species of coral have surprised researchers by showing an unexpectedly successful approach towards survival when seriously bleached. The discovery, derived from experiments on coral reefs in Hawaii , provides new insights into how these tiny animals face a multitude of environmental threats. The report by Ohio State University resear...

One in 14 men having a heart attack drive themselves to hospital

Seven per cent of men having a heart attack drove themselves to hospital and only 60 per cent went by ambulance, according to research published in the latest Journal of Advanced Nursing. The study, which looked at 890 heart attack patients admitted to six major teaching hospitals in Dublin, Southern Ireland, also found that it took women five times as long as men to go to casualty depar...

Study finds how organs monitor themselves during early development

How are you? In biological terms this question could involve a feedback loop that lets the body check in on itself and then act on that information. Although feedback loops are essential and they abound in biology, they aren't well understood. Feedback loops enable an organ such as the liver to detect if it is injured, ascertain if it is growing and developing normally, and if it needs to regener...

Bones repair themselves with bone marrow cells

A research project carried out by Juliette van den Dolder at the University of Nijmegen has shown that new bone cells can be grown into bone fractures with the help of specially prepared titanium mesh and bone marrow cells. Researchers inserted a titanium mesh scaffold into a bone fracture in a rat. They allowed bone marrow cells to grow on this. This resulted in new bone growth being sti...

Cancer Patients Might Be Able To Actually Help Themselves

New research looks at why and what can be done to activate the cells to destroy tumors. Researchers say the failure of these immune cells to kill // cancer may be due to different cell priming or suppressing mechanisms. Researchers now say that they have found a method to activate the anti-cancer cells in mice. For the study, researchers took bone marrow from breast cancer patients and...

People with low birth weight may help themselves in diabetes

New study says that people with low birth weight may help themselves from the incidence of diabetes with// controlled diet and controlling their body weights.
