Dark matter is called “dark” for a good reason. Although they outnumber particles of regular matter by more than a factor of 10, particles of dark matter are elusive. Their existence is inferred by their gravitational influence in galaxies, but no one has ever directly observed signals from dark matter
Champion of regeneration, the freshwater polyp Hydra is capable of reforming a complete individual from any fragment of its body. It is even able to remain alive when all its neurons have disappeared. Researcher the University of Geneva (UNIGE), Switzerland, have discovered how: cells of the epithelial type modify their genetic program by overexpressing a series of genes, among which some are involved in diverse nervous functions
The remnants of post-tropical cyclone Rick continued to linger in the Eastern Pacific Ocean on November 23. An animation of visible and infrared imagery from NOAA’s GOES-West satellite showed the weakening of Tropical Storm Rick into a remnant low pressure area from Nov. 21 to Nov.
An innovative approach to calibrating high-tech microscopes enables researchers to track the movement of single molecules in 3D at the nanoscale. read more
Comet C/2013 US10 Catalina shows off a compact green coma and two tails in this photo taken this morning (Nov. 22, 2015) at dawn from Arizona. The green color comes from carbon compounds fluorescing in UV sunlight
Researchers at Linköping University in Sweden have created analog and digital electronics circuits inside living plants. The group at the Laboratory of Organic Electronics (LOE), under the leadership of Professor Magnus Berggren, have used the vascular system of living roses to build key components of electronic circuits
More than half of all tree species in the world’s most diverse forest–the Amazon–may be globally threatened, according to a new study. read more
A James Cook University scientist says a new study shows more than half of all tree species in the world’s most diverse forest — the Amazon — may be globally threatened. read more
NASA’s Aqua satellite passed over Rick and captured a visible light image that showed the storm far off the coast of western Mexico. Rick continued to hang on to its status as tropical storm on Nov.
Scientists have solved a longstanding mystery about how some fish seem to disappear from predators in the open waters of the ocean, a discovery that could help materials scientists and military technologists create more effective methods of ocean camouflage. read more
The vast open ocean presents an especially challenging environment for its inhabitants since there is nowhere for them to hide. Yet, nature has found a remarkable way for fish to hide from their predators using camouflage techniques
There’s an ancient group of algae that evolved in the world’s oceans before our backboned ancestors crawled onto land. They are so numerous that their gigantic blooms can affect the weather, and they account for 30 to 40 percent of all photosynthesis in the world’s oceans
The twenty-first tropical depression of the Eastern Pacific Ocean season strengthened into a tropical storm on Nov. 19 and was renamed Tropical Storm Rick bringing the storm into a small elite group of late-season storms.
UK researchers have unearthed ancient fossil forests, thought to be partly responsible for one of the most dramatic shifts in the Earth’s climate in the past 400 million years. read more
West satellite provided images of the birth of the latest tropical depression in the Eastern Pacific Ocean. Tropical Depression 21E formed well southwest of the Coast of Mexico
SpaceX Crew Dragon will blast off atop a Falcon 9 rocket from Launch Pad 39A at NASA’s Kennedy Space Center in Florida for missions to the International Space Station. Pad 39A is undergoing modifications by SpaceX to adapt it to the needs of the company’s Falcon 9 and Falcon Heavy rockets, which are slated to lift off from the historic pad in the near future
On approach in July 2015, the cameras on NASA’s New Horizons spacecraft captured Pluto rotating over the course of a full “Pluto day.” The best available images of each side of Pluto taken during approach have been combined to create this view of a full rotation.

Host: Fraser Cain ( @fcain ) Special Guest: Miguel Drake-McLaughlin, Director of the new documentary, Sky Line, The Space Elevator Documentary. The film debuted at DOC NYC 2015 [Nov 12-19] – America’s largest documentary festival — and will be released on all major On Demand platforms on November 20th, 2015.
Comet C/2013 US10 Catalina photographed from high atop the Himalayas by Ajay Talwar with a 200mm lens on a tracking mount earlier this morning, Nov. 20, 2015. Copyright: Ajay Talwar If you love watching comets and live north of the equator, you’ve been holding your breath a l-o-n-g time for C/2013 US10 Catalina to make its northern debut. I’m thrilled to report the wait is over.
