Researchers worry that damage to the oceans could mean some species — and whatever chemicals they produce — will be lost before they’re found

Admin — Thu, 22 Jul 2010 20:45:20 +0000

Marc Slattery, a marine biologist by training, looks to sponges and coral as possible sources of drugs. As stationary species in the open ocean, these organisms have developed many chemical defenses to protect themselves. Slattery studies whether those chemicals could protect us, too. Maybe the same compounds that fend off fish could battle viruses, kill bacteria, and even fight cancer.

“These organisms are producing some nasty sorts of chemistry,” Slattery explains. “If you focus on the biotech side of things, there may be a drug in that” — or, he suspects, many.

After a long history of success on land, pharmacognosy — the search for substances in nature that have pharmaceutical potential — is finally getting its sea legs. Slattery, a pharmacognosy professor at the University of Mississippi, is one of the researchers scouring the oceans for cures.

Ocean acidification, warming water temperature and pollution all threaten sensitive corals and the symbiotic species that live on the reefs. Says Michael Lesser, a coral reef biologist at the University of New Hampshire who collaborates with Slattery, “We could lose something that could have great value to us as human beings, and not even know it.”

Aquapharm and AMRI Enter Into a Novel Marine Chemistry Collaboration

Admin — Thu, 22 Jul 2010 19:01:45 +0000

Aquapharm Biodiscovery, a leading marine biotechnology company, has signed a research agreement with Albany Molecular Research to identify novel drug-like compounds and scaffolds with anti-microbial and anti-inflammatory activity from Aquapharm’s marine natural products library derived from its extensive collection of marine micro-organisms.

Under the terms of this agreement, drawing on its substantial experience and expertise from previous screening campaigns with its terrestrial natural products library, AMRI will screen Aquapharm’s library against Gram-negative and Gram-positive bacteria and an undisclosed anti-inflammatory target and will isolate and elucidate the structures of novel hits. Aquapharm retains all rights to compounds resulting from the collaboration.

Scientists completing the last leg of MAR-ECO – an international research program and part of the Census of Marine Life, just returned from a voyage with samples of rare animals and more than 10 possible new species in a trip which they say has revolutionised their thinking about deep-sea life in the Atlantic Ocean.

The University of Aberdeen is leading the UK contribution to the project which involves scientists from 16 nations. Key collaborators in the UK include Newcastle University and the National Oceanography Centre.

The first joint expedition by the Republic of Indonesia and the United States to explore unknown deep-sea areas in Indonesian waters is currently under way.

The expedition is the first activity in a multi-year partnership to advance ocean science, technology and education. This is the first expedition of the NOAA Ship Okeanos Explorer, and the first joint international expedition to send live images and other data from sea to scientists on watch at Exploration Command Centers ashore both in Indonesia and the United States.

Jellyfish protein boosts cognitive function and wins patent protection

Admin — Fri, 16 Jul 2010 22:01:59 +0000

The jellyfish protein apoaequorin improves cognitive function in people with memory problems, according to interim data from a randomized controlled trial commissioned by Quincy BioScience which recently announced a successful application for patent protection. Derived from a jellyfish called Aequorea Victoria, aequorin is a calcium-binding protein.

The protein improved cognitive testing scores by 14 per cent in 60 days compared with the placebo in the randomized controlled Madison Memory Study. The trial focused on 35 adults who had a memory concern and an average age of 61.

The company also recently received a US patent covering the use of aequorin-containing compounds for the purpose of preventing and alleviating symptoms and disorders related to calcium imbalance. It first applied for the patent in 2005.

New Department of Marine Biotechnology and Institute of Fluorescence at UMBC, Baltimore, Maryland

Admin — Wed, 23 Jun 2010 12:24:19 +0000

From: Freeman Hrabowski, President, and Elliot Hirshman, Provost

We are delighted to announce the formation of the Department of Marine Biotechnology and the Institute of Fluorescence within the College of Natural and Mathematical Sciences. These exciting additions, which stem from the reorganization of the University of Maryland Biotechnology Institute, enhance and expand UMBC’s capacity in the campus priority areas of research infrastructure and environment and sustainability. In addition, our students will benefit from wide-ranging educational opportunities within these innovative research programs.

Both groups will continue to be based at the Columbus Center in downtown Baltimore, and USM is transferring budgetary support for associated faculty, staff and operating costs. The Columbus Center houses state-of-the-art research facilities, including a 16,200 m ²fully-contained, recirculating marine aquaculture facility, a versatile high-volume fermentation facility, a fully functional Biosafety level-three suite and a wide array of advanced molecular and biotechnology instrumentation including digital holographic microscopy.

Korea to explore ocean for future natural resources, including efforts to foster a marine biotechnology sector

Admin — Wed, 26 May 2010 16:27:37 +0000

South Korea imports most of its energy needs from outside, leaving itself extremely vulnerable to sudden changes in the price of oil and other raw materials.

Coupled with the rapid depletion of natural resources, surging demand from China, India and other fast-growing emerging economies raises the price of crude and other commodities sharply, weighing heavily on the Korean economy.

To secure a stable supply of energy resources and achieve a sustainable growth, the nation should turn its eye to the sea and make larger investments to explore a range of minerals on the sea bottom, Korea Ocean Research and Development Institute (KORDI) President Kang Jung-keuk stressed.

The institute is undertaking several economic feasibility studies on the construction of electric power plants using tidal currents in the West Sea, while working on the state-of-the-art technologies to produce bio-ethanol from marine algae.

`Generating electricity from tidal currents and extracting fuel from marine plants are environmentally friendly and renewable energies, which will help Korea reduce its imports of conventional fossil fuels, boost economic activities and create jobs. We will also make effort to foster a marine biotechnology sector by studying microorganisms that inhabit the most extreme living environments under the sea. By examining them, we could obtain materials for new medicines and create a range of benefits for humans,” Kang said.
