Jumping genes have essential biological functions

"Alu" sequences are small repetitive elements representing about 10% of our genome. Because of their ability to move around the genome, these "jumping genes" are considered as real motors of evolution. However, they were ...

Evolving a bigger brain with human DNA

The size of the human brain expanded dramatically during the course of evolution, imparting us with unique capabilities to use abstract language and do complex math. But how did the human brain get larger than that of our ...

The promiscuity of chemical probes discovered

Researchers at IMIM (Hospital del Mar Medical Research Institute) have applied a new computational methodology to anticipate the degree of selectivity of the molecules that are used to study protein functions and reduce the ...

Clearing up Europe's air pollution hotspots

Current air quality legislation in Europe will lead to significant improvements in particulate matter pollution, but without further emission control efforts, many areas of Europe will continue to see air pollution levels ...

Fighting decline of pollinators in Europe

Pollination is crucial to providing food security with 84% of European crops benefitting, at least in part, from insect pollination and 78% of temperate wildflowers needing biotic pollination. An estimated ~10% of the total ...

Near-perfect antibacterial materials

Ruthless with bacteria, harmless to human cells. New, durable antibacterial coatings of nanocomposites, developed at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, will in future help to ...

Dance of the planets in the evening sky

Armagh Observatory reports that the next two weeks provide a rare opportunity to observe the planets Venus, Mars and Uranus in the western evening sky after sunset, and the bright planet Jupiter rising high in the East about ...
