"Populations of bees around the world are declining, and viruses are known to contribute to these declines," said David Galbraith, research scientist at Bristol Myers Squibb and a recent Penn State graduate. "Despite the importance of bees as pollinators of flowering plants in agricultural and natural landscapes and the importance of viruses to bee health, our understanding of bee viruses is surprisingly limited."

Today's 'Planet Earth Report' --A Global Harbinger --"Climate Change Brought a Lobster Boom. Now It Could Cause a Bust"

"Warming waters in the Gulf of Maine have benefited lobsters and the lobstermen who trap them. But as temperatures rise further, will the industry reach a tipping point? The maximum water temperature that a lobster can tolerate is about 70 degrees Fahrenheit. Beyond that, “their system starts shutting down, one organ after another,” said Dr. Richard Wahle, director of the Wahle Lab and a leading expert on the America lobster. Consecutive days above this limit in Southern New England, he said, had lead to “mass mortality.”

"Alien Data" --Kepler "K2" Mission Yields Exciting New Planets Amid 50,000 Milky-Way Stars

"We found one of the most exciting planets that K2 has found in its entire mission, and we did it more rapidly than any effort has done before," says Ian Crossfield, an assistant professor of physics at MIT. "This is showing the path forward for how the TESS mission is going to do the same thing in spades, all over the entire sky, for the next several years."

From the Farside --"Alien Civilizations May Corral Stars As Energy Sources to Survive in an Expanding Universe"

The presence of dark energy in our universe is causing space to expand at an accelerating rate,  observes Dan Hooper, a senior scientist with Fermi National Accelerator Laboratory. As a result, over the next approximately 100 billion years, all stars residing beyond the Local Group will fall beyond the cosmic horizon and become not only unobservable, but entirely inaccessible, thus limiting how much energy could one day be extracted from them.

Neutron Stars May Unveil "Unknown 5th Force Between Normal Matter and Dark Matter"

Until today, nobody has conducted such a fifth force test with an exotic object like a neutron star. "There are two reasons that binary pulsars open up a completely new way of testing for such a fifth force between normal matter and dark matter," says Lijing Shao from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, Germany. "First, a neutron star consists of matter which cannot be constructed in a laboratory, many times denser than an atomic nucleus and consisting nearly entirely of neutrons. Moreover, the enormous gravitational fields inside a neutron star, billion times stronger than that of the Sun, could in principle greatly enhance the interaction with dark matter."

"Elusive!" --Planet's 1st Manta Ray Nursery Discovered (WATCH Today's 'Galaxy' Stream)

Known as the gentle giants of the sea, oceanic manta rays (Mobula birostris) are large, plankton-eating rays that live in the open ocean and can reach sizes of up to 7 meters (23 feet) in wingspan as adults. Oceanic mantas are typically found in subtropical and tropical waters around the world with aggregation sites commonly found far from coastal areas, making their populations hard to access and study. For this reason, major knowledge gaps remain in their basic biology, ecology, and life history. Baby mantas are virtually absent from nearly all manta populations around the world, so even less is known about the juvenile life stage.

"A New Picture of the Big Bang" --The Quantum Universe

Neil Turok, currently the Director and Niels Bohr Chair at the Perimeter Institute for Theoretical Physics in Ontario, Canada describes the quantum beginnings of the universe in the video below, on how ideas of the origin of the universe have changed over time, concluding with his current work on a ‘quantum’ beginning of the universe. In this theory the origin of the ‘astonishingly simple’ cosmos we see today, can be described with just a few fundamental numbers.

Today's "Planet Earth Report" --How to Save Antarctica (and Planet Earth)

Decisions made in the next decade will determine whether Antarctica suffers dramatic changes that contribute to a meter of global sea level rise. In a new study, scientists argue that time is running out to save this unique ecosystem, and that if the right decisions are not made to preserve Antarctica in the next ten years then the consequences will be felt around the world. Their results, published today in Nature, assess the state of Antarctica in 2070 under two scenarios, which represent the opposite extremes of action and inaction on greenhouse gas emissions and environmental protection.

"Beyond the Red Limit" --Major Photosynthesis Discovery Reveals that Earth's Plants Can Live in Ways Never Thought Possible (Today's Top Science Headline)

The vast majority of life on Earth uses visible red light in the process of photosynthesis, but the new type uses near-infrared light instead. It was detected in a wide range of cyanobacteria (blue-green algae) when they grow in near-infrared light, found in shaded conditions like bacterial mats in Yellowstone and in beach rock in Australia.
