New Broadband Speed Record
Researchers in Germany have achieved the fastest-ever data transmission on a single laser beam, and it just might carry your high-definition 3-D streaming movies of the future.
What's the Latest Development?
Researchers in a German lab have just increased broadband capabilities—by a lot. "The data rate is 26 terabits per second, 260 times faster than the 100-gigabit cabling used in broadband and equivalent to beaming 700 DVDs worth of data in a single second. While only the most data-intense scientific project today might find use for the new optical technology, Jürg Leuthold, a physicist at Karlsruher Institute for Technology, said it won’t be long before neighborhoods will have the need for such speed: "Commerce will find a way to fill the space," he said.
What's the Big Idea?
The development of faster data transfer speeds will run parallel to the emergence of cloud computing. As more and increasingly complex data is stored on remote servers, better transfer technology will be necessary to access it. The next developments must occur in hardware: "While there may be no practical limit to the data bandwidth glassy fiber-optic cabling can handle, the devices sending and receiving information on either end of the line do have limitations. 'Electronic computers can’t keep up. Above 100 gigabits, which is the industry standard now, processing gets difficult,' Leuthold said. 'To handle it, you would need fast processors that don't exist.'"

A NASA astronomer explains how astronauts dispose of their, uh, dark matter.
- When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
- Yes, there have been floaters in space. The early days of space exploration were a learning curve!
- Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.
The Harvard psychologist loves reading authors' rules for writing. Here are his own.
- Steven Pinker is many things: linguist, psychologist, optimist, Harvard professor, and author.
- When it comes to writing, he's a student and a teacher.
- Here's are his 13 rules for writing better, more simply, and more clearly.
A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
