Rapid imaging of granular matter

Thu, 21 Sep 2017 12:16:48 EDT

Granular systems such as gravel or powders can be found everywhere, but studying them is not easy. Researchers at ETH Zurich have now developed a method by which pictures of the inside of granular systems can be taken ten thousand times faster than before.



Researchers demonstrate quantum teleportation of patterns of light

Thu, 21 Sep 2017 12:15:13 EDT

Nature Communications today published research by a team comprising Scottish and South African researchers, demonstrating entanglement swapping and teleportation of orbital angular momentum 'patterns' of light. This is a crucial step towards realizing a quantum repeater for high-dimensional entangled states.



Ancient human DNA in sub-Saharan Africa lifts veil on prehistory

Thu, 21 Sep 2017 12:00:11 EDT

Study provides insights into how algae siphon carbon dioxide from the air

Thu, 21 Sep 2017 12:00:09 EDT

Two new studies of green algae—the scourge of swimming pool owners and freshwater ponds—have revealed new insights into how these organisms siphon carbon dioxide from the air for use in photosynthesis, a key factor in their ability to grow so quickly. Understanding this process may someday help researchers improve the growth rate of crops such as wheat and rice.



Signs of sleep seen in jellyfish

Thu, 21 Sep 2017 12:00:08 EDT

Jellyfish snooze just like the rest of us. Like humans, mice, fish and flies, the upside-down jellyfish Cassiopea exhibits the telltale signs of sleep, scientists report September 21, 2017 in the journal Current Biology. But unlike other animals that slumber, jellyfish don't have a central nervous system.



Scientists reveal the beautiful simplicity underlying branching patterns in tissue

Thu, 21 Sep 2017 12:00:07 EDT

In the centenary year of the publication of a seminal treatise on the physical and mathematical principles underpinning nature - On Growth and Form by D'Arcy Wentworth Thompson - a Cambridge physicist has led a study describing an elegantly simple solution to a puzzle that has taxed biologists for centuries: how complex branching patterns of tissues arise.



Scientists sequence asexual tiny worm—whose lineage stretches back 18 million years

Thu, 21 Sep 2017 12:00:03 EDT

A team of scientists has sequenced, for the first time, a tiny worm that belongs to a group of exclusively asexual species that originated approximately 18 million years ago—making it one of the oldest living lineages of asexual animals known. The work reveals how it has escaped the evolutionary dead end usually met by organisms that do not engage in sex.

Thu, 21 Sep 2017 11:10:01 EDT

An automated teller machine. The cash machine. In Britain, a cashpoint. ATMs, known for spitting out $20 bills (and imposing fees if you pick the wrong one), turn 50 years old this year. They're ubiquitous—and possibly still a necessity, despite the big changes in how people pay for things.

Hope to discover sure signs of life on Mars? New research says look for the element vanadium

Thu, 21 Sep 2017 11:03:36 EDT

The search for biology on neighbor planet Mars won't play out like a Hollywood movie starring little green men. Rather, many scientists agree if there was life on the Red Planet, it probably will present itself as fossilized bacteria. To find it, astrobiologists likely will need to decode the chemical analysis of rock samples performed by a rover (like the one NASA plans to send to Mars in 2020). Only then might humankind know conclusively that life exists beyond Earth.
