South Dakota Tech grad student finds rare whale


Maggie Hart, a South Dakota School of Mines and Technology paleontology student, recently found a rare, beaked whale that washed ashore on St. Catherine’s Island off the coast of Georgia.

At the time of her discovery in late July, Hart, a master’s degree candidate from Brea, Calif., was working on the St. Catherine’s Island Sea Turtle Conservation Program. In her studies of sea turtles, Hart is collaborating with Mike Knell of Council Bluffs, Iowa. Knell also is a Tech paleontology graduate student. Their work augments studies of fossil sea turtles found in South Dakota.

Hart measured the 13-foot whale, photographed it and collected its skull for identification by Dr. James Mead at The Smithsonian Institution’s Museum of Natural History. He identified it as a Sowerby’s beaked whale, probably a yearling female. The Smithsonian will retain the whale’s skull for confirmation and to serve as a voucher specimen for this rare species’ distribution.

Almost nothing is known about the natural history of the Sowerby’s beaked whale. They reach a length of approximately 18 feet long, travel in pods of up to 10 and presumably eat small fish and squid.

Sowerbys are the most northerly distributed beaked whale, living in the North Atlantic, from Massachusetts to Labrador, eastward to Iceland, the British Isles and western Europe. This is only the thirteenth Sowerby’s stranding documented in the western Atlantic. Prior to this, a stranding on the Gulf Coast of Florida was the only sighting in the temperate western Atlantic.

The St. Catherine’s Island Sea Turtle Conservation Program is an example of Tech students combining classroom and real-world experiences to add to the body of scientific knowledge.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.

They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...
