Why Some Petunias Are Blue
2014-01-02 15:01:54

Cell Press Researchers have uncovered the secret recipe to making some petunias such a rare shade of blue. The findings may help to explain and manipulate the color of other ornamental flowers, not to mention the taste of fruits and wine, say researchers who report their findings in the Cell Press journal Cell Reports on January 2nd. From the flowers' point of view, the findings also have important implications, since blue petals instead of red might spell disaster when it comes to...

It's not visible to the naked eye and you can't feel it, but up to 40 per cent of your body's energy goes into supplying the microscopic sodium-potassium pump with the energy it needs. The pump is constantly doing its job in every cell of all animals and humans. It works much like a small battery which, among other things, maintains the sodium balance which is crucial to keep muscles and nerves working. The sodium-potassium pump transports sodium out and potassium into the cell in a fixed...

A Danish-British research team has discovered a turbo switch in the vital calcium pump in our body's cells. In studies at the X-ray source DORIS at Deutsches Elektronen-Synchrotorn DESY in Hamburg and the European Synchrotron Radiation Facility ESRF in Grenoble the team discovered that the on-off switch of the pump has a previously unknown third position, which switches the pump into a turbo gear. The group of Henning Tidow from Aarhus University and Lisbeth Poulsen from the University of...

They say it's the little things that count, and that certainly holds true for the channels in transmembrane proteins, which are small enough to allow ions or molecules of a certain size to pass through, while keeping out larger objects. Artificial fluidic nanochannels that mimic the capabilities of transmembrane proteins are highly prized for a number of advanced technologies. However, it has been difficult to make individual artificial channels of this size "“ until now. Researchers...

The degradation of proteins and other macromolecules in cells is vital to survival. Disruption of this process can result in serious disease. The research group of Professor Thomas Jentsch (Leibniz Institute for Molecular Pharmacology, FMP/ Max Delbrck Center for Molecular Medicine, MDC, Berlin-Buch) has now succeeded in identifying an essential cellular process necessary for the transport and degradation of macromolecules in endosomes and lysosomes, respectively. In two studies published in...

Researchers at Rensselaer Polytechnic Institute have discovered new details about how bacteria generate energy to live. In two recently published papers, the scientists add key specifics to the molecular mechanism behind the pathogen that causes cholera. The work could provide a better understanding of this pathogen, while also offering insight into how cells transform energy from the environment into the forms required to sustain life. The findings may lead to a better understanding of how...

STORRS, Conn. "“ A team of scientists led by University of Connecticut plant biologist Roberto Gaxiola has discovered an overlooked genetic key to generating plants that are more productive, more drought resistant and can grow in soils low in nutrients. Their work is the first to successfully test in cells a 30-year-old hypothesis that explains the movement of a primary growth and development hormone through plants and is expected to prompt biology textbooks to be rewritten. The...
