Dreams are so strange and carry so much significance to us that we often feel the need to tell people about our nocturnal adventures, sometimes at tedious length.
But if you understand what goes on inside the brain as dreams take their course, they start to make a lot more sense. And dreams are much more important than you might think.
Here are some common questions answered about the nighttime hallucinations we call dreams.
MIT spin off company Ayar Labs is combining light and electronics to create faster, more efficient computers. The new optoelectronic chips are designed to speed up data transmission to and from conventional processor chips in a way that will also reduce energy consumption in chip-to-chip communications by 95 percent and could cut overall energy usages by large data firms by up to 50 percent.
Since the invention of the silicon chip 60 years ago, the power of computers has doubled every two years, but the speed at which computer systems work hasn’t shown quite such dramatic progress. The problem is one of data transmission and the bottlenecks that any technology runs into, slowing down the whole to the speed of its most sluggish part.
Think of a computer as like an air passenger system. If you concentrate on the aircraft, airport runway architecture, supply logistics, and air traffic control, it’s easy to speed up travel between, for example, New York and Washington DC to under one hour. That sounds fantastic, but if it takes you two hours to get through security at one hand and another two hours to collect your baggage at the other, then it’s faster to drive.

A new laser-based field instrument developed by a collaborative team of researchers can quantify methane leaks as tiny as 1/4 of a human exhalation from nearly…a mile away. The system, constructed around a dual-frequency comb spectrometer, provides efficient, accurate data collection at a fraction of the cost of previous technologies. The research was partially funded by DARPA’s Spectral Combs from UV to THz (SCOUT) program.

We’re never short of reasons to look up at the night sky — whether it’s the rare second blue moon we were just treated to, or a meteor shower.
But in case you need a little motivation to get out of the house and into the fresh air this month, we have a beautiful one for you: checking out the ever-changing celestial geometry above our heads.
This April, the gas giant Jupiter forms a rare and fleeting triangle with two bright stars in our night sky, and it’ll be visible with the naked eye if you know where to look.
Imagine driving and being warned when you’re too close to the edge of the road.
That’s exactly what space technology developed by German researchers can do, and it could be in Northland trucks in the next year.
Researchers from the German Aerospace Agency have been in Whangarei with the Intelligent Positioning System, which has been designed to navigate the rover on Mars.
This week and next, I’ll be visiting the Sonos stores in New York City (4÷12) and London (4÷17) for a free listening party celebrating the Voyager Golden Record, the iconic message for extraterrestrials launched into space 40 years ago. I’ll do a short multimedia presentation about this inspiring artifact and we’ll play the first ever vinyl release of the Voyager Golden Record that I co-produced with my friends Tim Daly and Lawrence Azerrad. Admission is free. No tickets remain for the New York City event but depending on the number of “no shows,” there may be availability at the door. And if you’re in London, please do RSVP right here! I hope to see you!
One of the ultimate goals of modern physics is to unlock the power of superconductivity, where electricity flows with zero resistance at room temperature.
Progress has been slow, but physicists have just made an unexpected breakthrough. They’ve discovered a superconductor that works in a way no one’s ever seen before — and it opens the door to a whole world of possibilities not considered until now.
In other words, they’ve identified a brand new type of superconductivity.
TOKYO (Reuters) — A series of shallow earthquakes shook parts of western Japan on Monday and authorities warned that further strong shaking is possible over the coming days.
