Air-sea interaction tower built off Martha’s vineyard

ASIT with platform in place

In the deep waters two miles south of Edgartown on Martha’s Vineyard, not far from where, two centuries ago, the likes of Captain Ahab and a thousand others kept their watch for the great white and his kin, we are now searching to understand another potential beast in those parts: the ocean and the weather.

But this is no allegory. Hoping to avoid any recurrence in these sometimes turbulent waters of the horrendous storms so intensely portrayed in Moby Dick as well as The Perfect Storm, the Office of Naval Research has built a tower bristling from top to bottom with sensors. The Air-Sea Interaction Tower will continually measure atmospheric and ocean conditions such as air temperature, humidity, solar radiation and carbon dioxide, as well as water temperature, salinity or salt content, wave height and direction, water circulation, current speed and direction, and sediment transport. It will directly measure momentum, heat, and mass exchange between the atmosphere and ocean. Anchored 50 feet down into the ocean floor, the tower extends 76 feet into the marine atmosphere. It will be maintained and operated by scientists at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts and will be connected by undersea cables to WHOI’s Martha’s Vineyard Coastal Observatory (MVCO).

Im Focus: Small Protein, Big Impact

In meningococci, the RNA-binding protein ProQ plays a major role. Together with RNA molecules, it regulates processes that are important for pathogenic properties of the bacteria.

Meningococci are bacteria that can cause life-threatening meningitis and sepsis. These pathogens use a small protein with a large impact: The RNA-binding...

Im Focus: K-State study reveals asymmetry in spin directions of galaxies

Research also suggests the early universe could have been spinning

An analysis of more than 200,000 spiral galaxies has revealed unexpected links between spin directions of galaxies, and the structure formed by these links...

Im Focus: New measurement exacerbates old problem

Two prominent X-ray emission lines of highly charged iron have puzzled astrophysicists for decades: their measured and calculated brightness ratios always disagree. This hinders good determinations of plasma temperatures and densities. New, careful high-precision measurements, together with top-level calculations now exclude all hitherto proposed explanations for this discrepancy, and thus deepen the problem.

Hot astrophysical plasmas fill the intergalactic space, and brightly shine in stellar coronae, active galactic nuclei, and supernova remnants. They contain...

Im Focus: Biotechnology: Triggered by light, a novel way to switch on an enzyme

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".

Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.
