Downloading NASA's dark matter data from above the clouds      (via sciencedaily.com)     Original source 

Data from a NASA mission to map dark matter around galaxy clusters has been saved by a new recovery system. The system allowed the retrieval of gigabytes of information, even after communication failed and the balloon-based telescope was damaged in the landing process.

'Bouncing' comets could deliver building blocks for life to exoplanets      (via sciencedaily.com)     Original source 

How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers have shown how comets could deposit similar building blocks to other planets in the galaxy.

Galactic 'lightsabers': Answering longstanding questions about jets from black holes      (via sciencedaily.com)     Original source 

The one thing everyone knows about black holes is that absolutely everything nearby gets sucked into them. Almost everything, it turns out. Astrophysicists have now determined conclusively that energy close to the event horizon of black hole M87* is pushing outward, not inward. The researchers have also created a way to test the prediction that black holes lose rotational energy and to establish it's that energy that produces the incredibly powerful jets.

New study reveals surprising insights into feeding habits of carnivorous dinosaurs in North America      (via sciencedaily.com)     Original source 

New research sheds light on the dining habits of ancient carnivorous dinosaurs from Jurassic rocks of the USA. A recent study explores the bite marks left on the ancient bones of the giant long-necked sauropod dinosaurs like Diplodocus and Brontosaurus by carnivorous theropod dinosaurs.

Tracking down quantum flickering of the vacuum      (via sciencedaily.com)     Original source 

Absolutely empty -- that is how most of us envision the vacuum. Yet, in reality, it is filled with an energetic flickering: the quantum fluctuations. Experts are currently preparing a laser experiment intended to verify these vacuum fluctuations in a novel way, which could potentially provide clues to new laws in physics. A research team has developed a series of proposals designed to help conduct the experiment more effectively -- thus increasing the chances of success.

Mysterious new moth species discovered in Europe      (via sciencedaily.com)     Original source 

European Lepidoptera (butterflies and moths), with a currently known inventory of approximately 11,000 species, are generally considered well-researched. However, a new genus and species from the Geometrid moth family tell a different story. The moth, named Mirlatia arcuata, is one of the most remarkable discoveries in Lepidoptera of recent decades.

Yucatán's underwater caves host diverse microbial communities      (via sciencedaily.com)     Original source 

With help from an experienced underwater cave-diving team, researchers have constructed the most complete map to date of the microbial communities living in the submerged labyrinths beneath Mexico's Yucatán Peninsula. Researchers found the cave system's microbiome is distinct from the nearby sea, and microbial communities vary between cave systems forming distinct 'neighborhoods.'

Hummingbirds' unique sideways flutter gets them through small apertures      (via sciencedaily.com)     Original source 

Hummingbirds are highly maneuverable fliers, flitting forward and backward as they home in on flowers. But in the dense foliage many inhabit, they often encounter gaps that are too narrow for their wingspan. Since they can't bend their wings in flight, how do they get through? Researchers used high-speed cameras to capture their movements, discovering two unique strategies: they sidle through while fluttering, or fold their wings in a tuck and glide.

Found at last: Bizarre, egg-laying mammal finally rediscovered after 60 years      (via sciencedaily.com)     Original source 

A long-beaked echidna named after Sir David Attenborough and last seen by scientists in 1961 has been photographed for the first time in an Indonesian tropical forest. An international team of researchers worked with local communities to deploy over 80 camera traps to film the elusive animal. Besides rediscovering the echidna, the team uncovered a wealth of species completely new to science, including beetles, spiders, and a remarkable tree-dwelling shrimp.

First live birth of a chimeric monkey using embryonic stem cell lines      (via sciencedaily.com)     Original source 

A team of researchers has reported for the first time the live birth of a monkey that contains a high proportion of cells derived from a monkey stem cell line. This 'chimeric' monkey is composed of cells that originate from two genetically distinct embryos of the same species of monkey. This has previously been demonstrated in rats and mice but, until now, has not been possible in other species, including non-human primates.

Animals like crickets use the ground to amplify calls      (via sciencedaily.com)     Original source 

When animals 'sing' sitting on the ground -- such as when crickets chirp -- their volume and reach increase dramatically, by as much as ten-fold. This result contradicts long-held beliefs in the field of animal communication, which presume the ground is a hindrance to sound transmission.
