From mirror-image biology to enhanced therapeutic proteins

Scientists have succeeded in reconstructing biomolecules in their mirror-image form. The researchers' goal is to create a mirror-image artificial protein synthesis system. Their aim is to produce mirror-image therapeutic proteins, such as antibodies, which would be protected from biological breakdown in the body and do not provoke any immune response.

Ocean sink for human-made carbon dioxide measured

Scientists have determined the amount of human-made carbon dioxide emissions taken up by the ocean between 1994 and 2007.

Tectonics in the tropics trigger Earth’s ice ages

Over the last 540 million years, the Earth has weathered three major ice ages -- periods during which global temperatures plummeted, producing extensive ice sheets and glaciers that have stretched beyond the polar caps. Now scientists have identified the likely trigger for these ice ages.

Vaccine study confirms sensitivity of cholera test

Recently, the sensitivity of fecal microbiological cultures for detecting cholera has come under question. Researchers investigated this claim using a 'vaccine probe' analysis of a completed cholera vaccine cluster randomized trial to support the sensitivity of conventional microbiological culture for cholera.

How a mitochondrial enzyme can trigger cell death

Cytochrome c is a small enzyme that plays an important role in the production of energy by mitochondria. It is also involved in signaling dangerous problems that warrant apoptosis, or programmed cell death. Using solid-state NMR, researchers have discovered that the signal induced by cytochrome c is more controlled than expected.

Novel methods for analyzing neural circuits for innate behaviors in insects

Insects show a variety of species-specific innate behaviors (instinctive behaviors). For example, a worker honeybee that has found flower nectar exhibits 8-shape waggle-dances upon returning to its beehive. A male moth that has detected a sex pheromone flies around to look for a female counterpart. There remain a number of questions about how a variety of innate behaviors are generated by functions of neural circuits in the insect brain.

Wolves lead, dogs follow — And both cooperate with humans

The statement is a bold one, especially as wolves have received a lot of negative attention in recent years. A recent study conducted by behavioral researchers, however, shows that dogs and wolves both work equally well with humans, albeit in different ways. The allegedly unequal brothers are thus much more similar than often assumed.

Researchers use algorithm from Netflix challenge to speed up biological imaging

Researchers have repurposed an algorithm originally developed for Netflix's 2009 movie preference prediction competition to create a method for acquiring classical Raman spectroscopy images of biological tissues at unprecedented speeds.
