Unmanned Underwater Vehicle Provides First 3-D Images Of Underside Of Antarctic Sea Ice

A National Science Foundation (NSF)-funded research team has successfully tested an autonomous underwater vehicle, AUV, that can produce high-resolution, three-dimensional maps of Antarctic sea ice. SeaBED, as the vehicle is known, measured and mapped the underside of sea-ice floes in three areas off the Antarctic Peninsula that were previously inaccessible. The results of the research […]

Philae Returns ‘Unprecedented Images’ Before Falling Asleep

The European Space Agency’s (ESA) ‘Philae’ probe made history last week by landing on a comet. The lander is now ‘asleep’ until sunlight reaches it. Last Wednesday, following a seven-hour descent, the ESA’s Rosetta mission soft-landed its Philae probe on the surface of Comet 67P/Churyumov–Gerasimenko. The ESA says that the successful landing was against the […]

Giving LEDs A Cozy, Warm Glow

When the 2014 Nobel Prize in physics was awarded this October to three Japanese-born scientists for the invention of blue light emitting diodes (LEDs), the prize committee declared LED lamps would light the 21st century. Now researchers from the Netherlands have found a novel way to ensure the lights of the future not only are […]

Neanderthals Not Sub-Species Of Modern Humans, According To Research

In an extensive, multi-institution study led by SUNY Downstate Medical Center, researchers have identified new evidence supporting the growing belief that Neanderthals were a distinct species separate from modern humans (Homo sapiens), and not a subspecies of modern humans. The study looked at the entire nasal complex of Neanderthals and involved researchers with diverse academic […]

New Paper Identifies Virus Devastating Sea Stars On Pacific Coast

Museum biological collections are the records of life on Earth and as such, they are frequently used to investigate serious environmental issues. When public health officials were concerned about the levels of mercury in fish and birds, for example, scientists studied museum specimens to assess historical changes in mercury contamination. Eggs in museum collections were […]
