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

...Salter recalled of that moment, when to both their great surprise the researchers witnessed how that little mishap had caused the macrophages to release bursts of calcium. Returning to dendritic cells, they found that by giving a deliberate poke with an empty microinjection tip it caused the same reaction...

World-first technology enables study of ancient bacteria

...sing temperatures (from an icy 2°C to over 100°C), great depth (several kilometres) and age (many millions of years) may contain most of the bacteria on Earth. Some of these bacteria produce methane that accumulates in "gas hydrates" ?a super concentrated methane ice that contains more carbon than all con...

...ms on DNA sequence level. "The STKE database is a great synergistic expansion to our BiblioSPherePE knowledge base. Following our strategy to only include highest quality data backed by well known scientific authorities, I couldn't think of any better source than STKE published by AAAS along with the lead...

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

...bacteria are extremely aggressive and could pose a great risk to sea animals, as disease is often caused by enzymes produced by bacteria." It is not yet clear to what extent these new vibrios affect marine animals in the wild. The next thrust of the work by Professor Austin and his team is to devise metho...

Solution to 'legionella'

This achievement has meant a great advance for human health. It is based on the biocidal and bacteriostatic effect of the SONOXIDE system, used in refrigeration towers of factory buildings and installations that are prone to be the focus for the proliferation of Legionnaires' disease....

Drugs from the deep blue

...hese questions. Discovering natural products is a great training tool because it requires skills in all areas of chemistry and a wide view of allied disciplines, Molinski said. "It's like a crossword puzzle where you have to find the clues," he said. "Natural products engage your intellectual curiosity w...

Women feel more pain than men, research shows

...it is understandable that chest pain is a cause of great anxiety for patients and that anxiety has an important role in the experience of chest pain," said Dr Keogh. "This research is also consistent with studies that suggest that men and women experience chest pain in different ways and that, compared to...

Firefly protein lets researchers monitor molecule linked to cancer

" Piwnica-Worms' laboratory has previously developed techniques that use luciferase to monitor...

DDT-resistant insects have additional genetic advantage that helps resistance spread
