Green light for clever algae

Researchers study extraordinary phycobiliproteins

30-09-2014

Phytoplankton not only constitutes the foundation of the food chain in the oceans, it also fixes carbon through photosynthesis and generates oxygen with the help of solar energy. A considerable part of phytoplankton is made up of cryptophytes, complex single-cell algae. In the course of ...

Algae deliver hydrogen

Modified enzymes enable efficient hydrogen production

29-09-2014

Hydrogen as a regenerative fuel produced in gigantic water tanks full of algae, which need nothing more than sunlight to produce the promising green energy carrier: a great idea in theory, but one that fails due to the vast amount of space required for the production process. Scientists from the ...

"Funnel" attracts bonding partners to biomolecule

Water movement as detection aid for molecules

26-09-2014

Water is a ubiquitous solvent in all life sciences – sometimes referred to as the "matrix of life". Contrary to earlier assumptions, it is not a passive witness of biochemical processes; rather, it participates in them actively. By influencing the movement of water molecules surrounding their ...

What drives peroxisomes to degrading pollutants

24-09-2014

Peroxisomes are vital cell components that degrade cellular toxins and long-chain fatty acids. Their malfunction may result in severe, often lethal disorders. RUB researchers (Medical Faculty) have been studying the precise working mechanisms of peroxisomes for 25 years. In collaboration with ...

An “anchor” that keeps proteins together

Researchers discover new scaffold protein

08-09-2014

All organisms react to different external and internal stimuli: if, for example, the hyphae fungus Sordaria macrospora is supplied with food, it produces fruiting bodies as part of its oestrous cycle. To initiate this reaction, signals have to be transmitted within the cell, which are conveyed by ...

Why HIV patients develop dementia

Researchers track harmful immune reactions in the brain

05-09-2014

Since the introduction of the combination anti-retroviral therapy (cART) in the mid-90s, the life expectancy of HIV patients has significantly improved. As a result, long-term complications are becoming more relevant: almost every second HIV patient is affected by neurocognitive disorders, which ...

Proteins that replace silicon: A semi-artificial leaf faster than “natural” photosynthesis

22-08-2014

A cooperation between chemists and biologists from the Ruhr-University Bochum resulted in a new method for the very efficient integration of photosynthetic proteins in photovoltaics. Their recent report in Chemistry - a European journal, selected as a very important paper (VIP) by the journal, ...

Efficient production of hydrogen by algae

20-08-2014

Microalgae need only sunlight and water for the production of hydrogen. However, in order to make hydrogen production by microalgae economically feasible their efficiency has to be increased by 1-2 orders of magnitude. In the current issue of Energy and Environmental Science scientists from the ...

When wine hits the right nerve

Neither the sense of taste nor the sense of smell is responsible for barrique appreciation

07-05-2014

If wine leaves a bitter, cotton-like coating on the tongue, neither the sense of taste nor the sense of smell is responsible. The traditional oak barrel character, also called barrique character, is perceived via the trigeminal nerve, which is responsible for, among other things, pain and ...

Small peptides as potential antibiotics

Research team decodes the effects of an antimicrobial peptide on bacterial cells

26-03-2014

Small peptides attack bacteria in many different ways and may well become a new generation of antibiotics. Biologists at the Ruhr-Universität Bochum (RUB) have been researching how such peptides kill bacterial cells. “It is quite possible that, in ten years time, all of the currently marketed ...
