Novel insights in the attachment of the bacterial carcinogen Helicobacter pylori
The gastric pathogen Helicobacter pylori is highly adapted to survival in human stomach and responsible for the majority of peptic ulcer and gastric cancer cases worldwide. It's survival strategy is adhere to blood group sugars found on gastric mucus and underlying cells. Scientists at the labs of Han Remaut (VIB/Vrije Universiteit Brussel) and Thomas Borén (Umeå University Sweden) provide detailed structural and functional. (2016-01-14)

Tiniest chameleons deliver most powerful tongue-lashings
A new study reports one of the most explosive movements in the animal kingdom: the mighty tongue acceleration of a chameleon just a couple of inches long. The research illustrates that to observe some of nature's best performances, scientists sometimes have to look at its littlest species. (2016-01-04)

A 'ghost from the past' recalls the infancy of the Milky Way
When our galaxy was born, around 13,000 million years ago, a plethora of clusters containing millions of stars emerged. But over time, they have been disappearing. However, hidden behind younger stars that were formed later, some old and dying star clusters remain, such as the so-called E 3. European astronomers have now studied this testimony to the beginnings of our galaxy. (2015-12-10)

Experiment attempts to snare a dark energy 'chameleon'
Is dark energy hard to detect because it's hiding from us? According to a recent theory, hypothetical particles called chameleons vary in mass depending on nearby matter: in the vacuum of space, they have a small mass and large reach, pushing space apart. In the lab, surrounded by matter, they have a large mass and small reach, making them difficult to detect. A UC Berkeley experiment seeks to find chameleons by lessening the screening. (2015-08-20)

UCLA physicist tests theories of dark energy by mimicking the vacuum of space
Besides the atoms that make up our bodies and all of the objects we encounter, the universe contains mysterious dark matter and dark energy. The latter, which causes galaxies to accelerate away from one another, constitutes the majority of the universe's energy and mass. Paul Hamilton, a UCLA assistant professor of physics and astronomy, reproduced the low-density conditions of space to precisely measure this force. (2015-08-20)

Chameleons' eyes are not so independent
It looks as if chameleon's eyes move independently, however, if the eyes are truly independent, the right side of the brain should only know what the left eye is seeing and vice versa. But it turns out, based on experiments carried out in Israel, that while they can track different objects on opposite sides of their heads, each eye knows where the other is directed, so chameleon's eyes are not independent. (2015-07-08)

Biodiversity: 11 new species come to light in Madagascar
Madagascar is home to extraordinary biodiversity, but in the past few decades, the island's forests and associated biodiversity have been under greater attack than ever.
