Russia to build world's largest DNA databank

Rhesus monkeys in Puerto Rico remain vital to research
Cayo Santiago, Puerto Rico (UPI) Dec 30, 2014 - Scientists hope findings from a new research project involving a colony of feral monkeys in Puerto Rico could have implications for human learning problems and neurological disorders like autism.

Humans share a large percentage of their genes with monkeys, which makes them vital for all kinds of research. And rhesus macaque monkeys (Macaca mulatta), one of the most iconic Old World species, exhibits remarkably complex cognitive abilities, making them ideal subjects for psychological and behavioral studies.

That's why the large colony of rhesus monkeys living on a remote Puerto Rican island has proved so important to researchers through the decades.

Most recently, an international team of scientists -- including researchers from Yale, Duke, Chicago and Germany's Leipzig University -- has been observing the local population of rhesus monkeys in order to better understand the neural processes key in monkey (and human) decision-making. The research is being led by biologists at the University of Puerto Rico's Caribbean Primate Research Center, or CPRC.

The monkeys being studied are part of a colony of some 1,200. The population has flourished ever since being brought from India to Cayo Santiago, a small island off the coast of Puerto Rico, 75 years ago. Rhesus monkeys are native to much of southern Asia, but feral populations exist all over the world, including South Carolina and Florida.

Cayo Santiago's feral colony -- which has propagated some 11,000 individuals over 12 generations -- is ideal for research as it has remained isolated from other species.

"In fact, this population is unique in the world because we have the purest monkey that can exist since they have not crossbred with any other species," study leader Angelina Ruiz, CPRC associate director, told EFE.

The monkeys were first brought to the island for biomedical research and they continue to be used for similar purposes. Researchers with the National Institutes of Health continue to rely on the colony for disease-free monkey test subjects -- for AIDS studies and other medical research.

Great Britain is home to the Frozen Ark project, an effort to preserve the DNA and living cells of endangered species. The San Diego Zoo has been operating a so-called frozen zoo -- freezing animal semen, feces and other samples in liquid nitrogen -- since 1976.

But Russia's Moscow State University aims to outdo them both, several times over. The research university recently received a grant from Russia's government -- the country's largest scientific grant ever -- to build a genetic library, filled with frozen DNA from every living creature on the planet.

"I call the project 'Noah's Ark,'" MSU rector Viktor Sadivnichy recently told reporters. "It will involve the creation of a depository -- a databank for the storing of every living thing on Earth, including not only living, but disappearing and extinct organisms."

Construction of the databank facility will commence quickly, with plans for the depository to be completed by by 2018.

"It will enable us to cryogenically freeze and store various cellular materials, which can then reproduce. It will also contain information systems. Not everything needs to be kept in a petri dish," explained Sadivnichy.

The new database will first be sourced with materials already being held by the university's many research departments. All of its departments will also be involved in sourcing new material.

While the new database will be grand in its aims, it's not entirely unique; the country has also begun work to create a storage facility in Siberia that will use thick, ice-cold permafrost to preserve a variety of seed and plant samples for posterity.

FWS to review status of monarch butterfly
Washington (UPI) Dec 30, 2014 - The most iconic butterfly in the United States, the monarch butterfly, may warrant federal protections. On Monday, the U.S. Fish and Wildlife Service announced it would begin a year-long review of the butterfly's protection status.

If biologists determine the beleaguered butterfly to be significantly threatened by extinction, officials could decide to list the monarch as "endangered" under the Endangered Species Act -- a federal law that affords plants and animals special protections.

The status review was initiated in response to a petition put forward by the Center for Biological Diversity, the Center for Food Safety, the Xerces Society for Invertebrate Conservation and Dr. Lincoln Browe.

Monarchs and their large orange and black patterned wings are found all across the United States. A large portion of the insect's population makes an exhausting yearly migration -- sometimes as long as 3,000 miles -- from North America to Mexico.

"This journey has become more perilous for many monarchs because of threats along their migratory paths and on their breeding and wintering grounds," FWS officials wrote in a released statement.

Though their numbers appeared to bounce back in 2014, monarch populations have rapidly declined over the last decade. While pesticide toxicity has taken some of the blame for their plummeting numbers, habitat loss is the insect's most significant threat. The caterpillars that turn into monarchs feed exclusively on milkweed, a flowering plant that's been decimated by the expansion of industrial agriculture across America's heartland.

The Fish and Wildlife Service will field public comments on the impending status review for the next 60 days.

SFU scientists help put bedbugs to bed forever
Burnaby, Canada (SPX) Dec 29, 2014
The world owes a debt of gratitude to Simon Fraser University biologist Regine Gries. Her arms have provided a blood meal for more than a thousand bedbugs each week for five years while she and her husband, biology professor Gerhard Gries, searched for a way to conquer the global bedbug epidemic. Working with SFU chemist Robert Britton and a team of students, they have finally found the so ... read more
