Bursts of waves drive immune system 'soldiers' toward invaders

...they found that molecules of Hem-1 don't move, but pass information between molecules to generate a wave. The research is now focusing on how external signals influence this wave generator to guide the cells. They also want to learn if the wave action they have discovered in neutrophils also controls m...

MIT creates 3-D images of living cell

...ell is compared with a reference wave that doesn't pass through it. A 2D image containing information about refractive index is thus obtained. To create a 3D image, the researchers combined 100 two-dimensional images taken from different angles. The resulting images are essentially 3D maps of the refrac...

Discoverer of Sly Syndrome finds way of delivering medicine to fight rare genetic disorder

... right amount of epinephrine allowed the enzyme to pass into the brain of older mice, which means we reinduced the way to get the enzyme where it is needed, Banks says. Epinephrine is a drug that treats cardiac arrest and is given to open the airways of asthma patients who have difficulty breathing. Dis...

A new plant-bacterial symbiotic mechanism promising

...nutritive elements to the bacteria which in return pass on the nitrogen they have stored up. These interactions improve crop yields of leguminous plants that are crucial for human diet (soybean, peas, ground nuts and so on) and as animal feed (alfalfa, clover, sainfoin). In addition, cultivation of leg...

Outwitting pesky parasites

While Ha says most conventional breeders rely on phenotypic evaluations of plants to select the plant with most desirable traits, this process takes time and money. For e...

Study provides new data about the laws governing embryo development in organisms

These pathways have been conserved across evolution, and therefore studies using models such as the fruit fly provide information about these same processes in humans and other animals. The Developmental Bio...

New way to target and kill antibiotic-resistant bacteria found

The researchers analyzed relaxase because it plays a crucial role in conjugation. The enzyme starts and stops...

Birds take cues from their competitors

Now, a new study reveals that some birds learn not only from each other, but also from their competitors. The findings appear online on July 5th in Current Biology, a Cell Press publication. Thr...

Insects to solve crimes

This is why, by the time a crime is investigated, there may be no insect larvae. But there may be other insects in the area which can also provide clues. After studies of...

These proteins, called Necl1 and Necl4, belong to a larger family of cell adhesion molecules, so called because they sit on the outer membranes of cells and help them to stick together.

In contrast, some females cheat with males outside their group if they sense their mates are too genetically similar to themselves.
