What’s behind Mediterranean diet and lower cardiovascular risk?

A new study offers insights from a cohort study of women in the U.S. who reported consuming a Mediterranean-type diet.

Scientists to produce anti-cancer drugs in yeast

Nature is so complex that natural molecules used for i.e. cancer treatment still can't be produced by chemical synthesis. Today, major chemical and pharmaceutical companies harvest large amounts of rare plants and seeds in order to extract valuable substances.

How ice particles promote the formation of radicals

The production of chlorofluorocarbons, which damage the ozone layer, has been banned as far as possible. However, other substances can also tear holes in the ozone layer in combination with ice particles, such as those found in clouds. Researchers have discovered a possible mechanism for this.

How fruit flies ended up in our fruit bowls

Fruit flies can be a scourge in our homes, but to date no-one has known how they became our uninvited lodgers. For decades, researchers have searched for their origins and now a Swedish-American research team has succeeded. They have also discovered that fruit flies in the wild are far more picky than their domesticated counterparts, a factor that long ago probably prompted the flies to move in with people.

Molecular insights into spider silk

Spider silk belongs to the toughest fibers in nature and has astounding properties. Scientists have now discovered new molecular details of self-assembly of a spider silk fiber protein.

One out of three rivers in the Iberian Peninsula is affected by salinization

One out of three rivers in the Iberian Peninsula has salinization mainly due the impact of agricultural activity and territory urbanization. This environmental problem will affect hydric ecosystems due global warming, the growing use of water and the exploitation of soil natural resources.

Bacterial ‘sleeper cells’ evade antibiotics and weaken defence against infection

New research unravels how so-called bacterial persister cells manipulate our immune cells, potentially opening new avenues to finding ways of clearing these bacterial cells from the body, and stopping recurrence of the bacterial infection.

Seeing and avoiding the ‘blind spot’ in atomic force measurements

Researchers have discovered a 'blind spot' in atomic force microscopy -- a powerful tool capable of measuring the force between two atoms, imaging the structure of individual cells and the motion of biomolecules.

Double the stress slows down evolution

Bacteria evolve resistance to antibiotics more slowly if they also have to defend themselves against predators.

Biggest mass extinction caused by global warming leaving ocean animals gasping for breath

By combining ocean models, animal metabolism and fossil records, researchers show that the Permian mass extinction in the oceans was caused by global warming that left animals unable to breathe. As temperatures rose and the metabolism of marine animals sped up, the warmer waters could not hold enough oxygen for their survival.
