Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

...ts, are all very similar. "This is particularly true of the innate immune system, which is the fast-acting battery of defences that recognise and kill microbes to prevent infections from occurring. "Some remarkable discoveries have been made using insects that have subsequently allowed important adv...

A cherry on top: Tart cherries may alter heart/diabetes factors

...e rats that did not receive cherries. The same was true for those on the 10-percent cherry diet, compared with rats that received a diet with an equivalently high level of carbohydrates not from cherries. The researchers also measured plasma TEAC, a measure of antioxidant capacity in the blood on whic...

How to look at dinosaur tracks

...n. For example, dinosaur tracks may still exist as true tracks, that is, the original prints left in the g... digits and impressions of claws. However, the true tracks may be filled with sediment or the original tracked surface may have eroded away. In the latt...

Surprising origin of cell's internal highways

...live-cell imaging techniques that could reveal the true origins of these structures. "The Golgi apparatus is very close to the centrosome," said Kaverina. "So if you're not looking at it precisely, it is hard to distinguish between the centrosome and Golgi." To get a close look, Kaverina and colle...

The kapok connection -- Study explains rainforest similarities

...he role of oceanic dispersal to see if the same is true for other species and for entire plant communities. "This tree has become locally extinct in parts of the Peruvian Amazon as a result of overexploitation for plywood," Dick said. "It might be saved from widespread extinction by continuing to invad...

Exploring the dark matter of the genome

...lled "junk." Like dark matter in the universe, the true nature of heterochromatin was unknown. Now membe... what holds the galaxies together, and the same is true of the genome. We're pretty good at understanding how individual genes work, but we don't understand...

Progress toward an antitumor vaccine

...which can suppress the immune response against the true target, the glycoprotein.” This team has now found a good anchoring technique: Their anchor is a thioether (two carbon atoms coupled together through a sulfur atom). To this end, the carrier protein is first equipped with a spacer, which has an al...

Studies to find better ways to preserve human eggs, ovarian tissue under way

...s, if you use lower concentrations, you cannot get true vitrification.” The agents are needed to intercept water so it won’t form ice. Interestingly if small ice crystals form during cooling, they can get larger during de-vitrification, which takes place in seconds. “We developed a solution where we ca...

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

...es, the new findings show that the opposite may be true when it comes to Alzheimer’s disease. Perhaps inflammation is playing the role of protector and is acting more like an ambulance crew helping at the site of a road wreck, not causing the crash. The work suggests that doctors not rush in to turn of...
