Life’s a beach


Scientists at Plymouth Marine Laboratory are developing new methods to rapidly assess the biodiversity of living organisms on beaches and other marine environments. They have already found many new creatures which have not been classified in previous studies.

The research is part of a programme called RAMBLERS (Rapid Assessment of Marine Biodiversity Linked to Environmental Remediation Studies.)

One of the objectives is to create a comprehensive inventory of marine plants and animals. The research, funded by Defra, also investigates how elements of the flora and fauna within this small community can be used as a representative sample for total biodiversity.

Current and historical data will be incorporated into new statistical software to predict the future distribution of life over large areas and long timescales. They will help to distinguish between natural biodiversity changes and those that are due to human activities, such as fishing, dredging, and oil and gas exploration.

The Plymouth scientists have collected hundreds of species in just a few buckets of sand taken from a beach on the Isles of Scilly, an ideal location for biodiversity studies as the marine environment there is relatively clean and undisturbed.

Marine scientist Dr Paul Somerfield from Plymouth Marine Laboratory, said: “Most of these new species are microscopic worms and shrimps, too small to be seen with the naked eye. It is truly amazing just how little we really know about the marine environment and the biodiversity it supports, even in familiar places where many studies have been done before. ”

Head of Marine Science R&D, Paul Leonard, said, "Defra needs successful tools to determine biodiversity. I am delighted that we have been able to make such positive progress. The researchers have a good track record of determining environmental quality at pristine and historically contaminated sites. This is of great benefit to Defra when we are drawing up licensing conditions."

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
