Sweet bribes for ants are key to crops bearing fruit, study shows

Added: 23.06.2017 11:05 | 0 views | 0 comments


Some flowering crops, such as beans and cotton, carefully manage the amount and sweetness of nectar produced on their flowers and leaves, to recruit colonizing ants which deter herbivores. This strategy balances their needs for defense and reproduction.

#zrodlo

Using a powerful astronomical technique called gravitational lensing, the NASA/ESA Hubble Space Telescope made a stunning discovery — the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the Big Bang. The galaxy in question, called MACS 2129-1, lies approximately 10 billion light-years away [...]

Tropical viruses: Coming soon to Europe?

The mosquito-borne viral disease Chikungunya is usually found in tropical areas. Researchers have now discovered how climate change is facilitating the spread of the Chikungunya virus. Even if climate change only progresses moderately – as scientists are currently observing – the risk of infection will continue to increase in many regions of the world through the end of the 21st century. If climate change continues unchecked, the virus could even spread to southern Europe and the United States.

A research group has found a long-sought explanation for the apparent contradictions implicit in the composition of lunar and Martian meteorites. They were able to demonstrate how meteorites could contain within narrow spaces minerals whose formation conditions are quite different. These findings provide new impetus for meteorite research.

Mechanical structures in steerable cars are optimized to fit exactly one particular shape of the toy. If designers want to reuse such a mechanism with different shapes, the necessary adjustments to the components were often unmanageable for non-experts. Scientists have developed an interactive design tool that allows users to easily adjust a mechanical template to the shape of their choice.

A subgroup of patients with osteosarcoma -- a form of bone cancer -- could be helped by an existing drug, suggest scientists. In the largest genetic sequencing study of osteosarcoma to date, scientists discovered that 10 percent of patients with a genetic mutation in particular growth factor signalling genes may benefit from existing drugs, known as IGF1R inhibitors.

A unique amino acid for brain cancer therapy

Added: 23.06.2017 8:50 | 0 views | 0 comments

#zrodlo

Photodynamic therapy is often used to treat brain tumors because of its specificity — it can target very small regions containing cancerous cells while sparing the normal cells around it from damage. It works by injecting a drug called a photosensitizer into the bloodstream, where it gathers in cells, and then exposing the drug-filled cells to light. When the photosensitizer is exposed to this light, it emits what is known as a reactive oxygen species (ROS) that causes the cells to die.
