Latency is so ingrained into modern communication we almost forget about it but in live or recorded events, like performances or rehearsals over a long distance, it is crippling.

 When recording a soundtrack over a pre-recorded base, the latency is perceptible to the human ear if a delay of 15-20 milliseconds occurs - the track seems displaced from the rest, giving the sense of being poorly played. To resolve displacement over long distances, elements such as sound capture, sound coding and decoding servers, intermediate network elements, lines of communication and the software used all must be factored in.

Researchers have discovered proof that acoustic phonons, the elemental particles that transmit both heat and sound, have magnetic properties. 

In a new paper, the authors describe how a magnetic field roughly the size of a medical MRI reduced the amount of heat flowing through a semiconductor by 12 percent. But because the phonons reacted to the magnetic field, the particles must be sensitive to magnetism.  

Patients with carpal tunnel syndrome are more than twice as likely to have migraine headaches, according to data derived from nearly 26,000 Americans responding to a national health survey. Among other questions, participants were asked whether they had had carpal tunnel syndrome during the past year or "severe headache or migraine" during the past three months.

Patients with carpal tunnel syndrome have symptoms such as hand numbness and weakness, resulting from pressure on the median nerve in the wrist. 

The association also runs in the other direction, with migraine patients having higher odds of carpal tunnel syndrome, say Dr. Huay-Zong Law and colleagues of University of Texas Southwestern Medical Center at Dallas.

To combat possible climate change due to greenhouse gases, a mix of alternative energy sources (except nuclear for the United States) and geoengineering schemes have been proposed. One idea proposes that ocean pipes could facilitate direct physical cooling of the surface ocean by replacing warm surface ocean waters with colder, deeper waters. 

A new study from a group of Carnegie scientists determines that these types of pipes could actually increase global warming quite drastically. 

In 1670, the greatest astronomers, including Cassini and Hevelius, the father of lunar cartography, documented the appearance of a new star in the skies.

Hevelius described it as nova sub capite Cygni — a new star below the head of the Swan — and now it is officially known it by the name Nova Vulpeculae 1670.  It lies within the boundaries of the modern constellation of Vulpecula (The Fox), just across the border from Cygnus (The Swan) and is also referred to as Nova Vul 1670 and CK Vulpeculae, its designation as a variable star. 
 
Historical accounts of novae are rare and Nova Vul 1670 is both the oldest recorded nova and the faintest nova when later recovered.

In a complex system like the human body, it's no surprise things can sometimes go wrong in development but evolution has made the system rather forgiving. When children inherit chromosomes from their parents, some minor genetic changes frequently occur without consequence but chromothripsis - chromosomal shattering - has been linked to severly affected children of healthy mothers in a small study.
