Ordering Your Own Tricked-Out Submarine

"The hoovering capabilities of the NEYK are second to none," reads a blurb on the Web site of Ocean Submarines, which bills itself as specializing in the development and designs of underwater craft -- particularly those, it appears, for the private use and enjoyment of the uber-wealthy.

One of the company's projects, for instance, involved the building of an entirely new line of submarines that boasted a length of 64 feet that could plunge to depths of 1,000 feet.

Below this description, a large photo depicts one of the company's submarines nestled alongside of an anchored yacht, with a person stepping onto the sub's deck. While the sub looks dramatically smaller by comparison, 60+ feet of length is nothing to sneeze about. Nor is the well-appointed interior.

For what is believed to be the first time, scientists from the British Geological Survey and Lancaster University have better determined the degree to which the presence of nitrate, a variation of nitrogen with potentially harmful effects, impacts the public water supply of England.

And while England's public water infrastructure currently removes significant quantities of nitrogen, water that leaks from pipes may be a major source of nitrogen being transmitted into the environment.

In fact, researchers say, nitrogen levels in the lakes, groundwater, rivers, and soils of England has increased sharply over the last hundred or so years, mostly because people use inorganic forms of nitrogen fertilizer to boost crop production in farming operations.

Monitoring Anemia Via Fingernail Color

Biomedical engineers have come up with a non-invasive method to detect anemia in humans.

The app, an alternative to a blood test, analyzes photos of fingertips captured on a smartphone to figure out whether the amount of hemoglobin is low enough to signal an alarm.

Principal investigator Wilbur Lam, MD, PhD, an associate professor of pediatrics at Emory University School of Medicine, said, “All other ‘point-of-care’ anemia detection tools require external equipment, and represent trade-offs between invasiveness, cost, and accuracy. This is a standalone app that can look at hemoglobin levels without the need to draw blood.”
