• 15:24 Social media used to collect information on marine wilderness

  Read the story at PhysOrg
  (Phys.org) -- Researchers from Murdoch University's Cetacean Research Unit are working with colleagues from Duke University in the US and Marine Ventures Foundation on an innovative project that will use social media to collect information on one of the world's last great marine wildernesses. Ashley Yeager from Duke University explains.

• 15:24 The myth of the disconnected telecommuter

  Read the story at PhysOrg
  (Phys.org) -- The assumption that employees who regularly telecommute will feel less attached to the organization they work for due to feeling isolated and disconnected is a myth, according to a study led by a communication researcher at the University of Wisconsin-Milwaukee (UWM).

• 15:24 USDA links gene flow between weedy and domesticated rice to rising carbon dioxide levels

  Read the story at PhysOrg
  (Phys.org) -- New research at the U.S. Department of Agriculture (USDA) confirms that rising levels of atmospheric carbon dioxide facilitate the flow of genes from wild or weedy rice plants to domesticated rice varieties. As a result, domesticated plants could take on undesirable weedy characteristics that may interfere with future rice production.

• 13:24 Crowding causes cells to produce an orderly matrix of molecules

  Read the story at PhysOrg
  When researchers conduct experiments on the way cells grow and respond to outside cues, they tend to use solutions that are much more dilute than the crowded environments found inside living cells. Now, new research from MIT shows that this dilute environment may skew the results of such experiments.

• 13:24 New CO2-removing catalyst can take the heat

  Read the story at PhysOrg
  (Phys.org) -- The current method of removing the greenhouse gas carbon dioxide (CO2) from the flues of coal-fired power plants uses so much energy that no one bothers to use it. So says Roger Aines, principal investigator for a team that has developed an entirely new catalyst for separating out and capturing CO2, one that mimics a naturally occurring catalyst operating in our lungs. With this success, the Laboratory has become a world leader in designing catalysts that mimic the behavior of natural enzymes.

• 13:24 Nvidia says Kai platform will turn price tide for tablets

  Read the story at PhysOrg
  (Phys.org) -- In March, Nvidia gave some signs that they were working to lower the cost of their Tegra 3 processors and they suggested consumers might see prices for Android tablets as low as $199. Connect the dots? At the company’s annual investors meeting last week, the dots connected and are making this week’s news. For those marking the history of the tablet, remember the date, May 21, 2012. That was this meeting date at Santa Clara, where Nvidia management told its audience what strategies and growth were on tap. Vice President of Investor Relations, Rob Csonger, did the tablet talking.

  Read the story at PhysOrg
  (Phys.org) -- With cameras set up in Sumatra looking for medium- and small-sized wild cats, such as leopards, a research group involving the University of Delaware's Kyle McCarthy, found images of something else entirely -- a rabbit. Not just any ordinary rabbit, but a Sumatran striped rabbit, one of the world's rarest species and one that had been captured on film only three times before.

• 13:24 Social welfare cuts ultimately come with heavy price, researchers say

  Read the story at PhysOrg
  (Phys.org) -- Slashing government funding for Medicaid, food stamps and other programs that serve the poor – while politically popular with some lawmakers and many conservatives – may do more harm than good to the economy and cost taxpayers more in the long run, suggests a report by researchers at the University of Illinois.

• 13:24 Study cracks a secret of methanol production

  Read the story at PhysOrg
  (Phys.org) -- What’s the best way to make methanol? The question is more pressing than it sounds. Not only is methanol an important industrial chemical – some 50 million tons are used each year to make plastics and other products – but it could also become the basis of a clean energy economy that actually reduces global warming by turning a potent greenhouse gas, carbon dioxide, into fuel.

• 13:24 Study reveals who profits and who incur losses from provision of immediacy in the stock market

  Read the story at PhysOrg
  While mutual funds and issue of stocks cause price impact, hedge funds and repurchase of shares decrease this. The doctoral dissertation by Kalle Rinne, M. Sc. (Econ.), studies how demand and provision of immediacy affects the market's functioning and what the roles are of different market parties with regard to provision of immediacy.

  Read the story at PhysOrg
  Marine scientists studying life around deep-sea vents have discovered that some hardy species can survive the extreme change in pressure that occurs when a research submersible rises to the surface. The team's findings, published in Conservation Biology, reveal how a species can be inadvertently carried by submersibles to new areas, with potentially damaging effects on marine ecosystems.
