REINFORCEMENT LEARNING ALGORITHMS SCORE HIGHER THAN HUMANS, OTHER AI SYSTEMS AT CLASSIC VIDEO GAMES
A team of researchers at Uber AI Labs in San Francisco has developed a set of learning algorithms that proved to be better at playing classic video games than human players or other AI systems. In their paper published in the journal Nature, the researchers explain how their algorithms differ from others and why they believe they have applications in robotics, language processing and even designing new drugs.
A PROTOTYPE OF AN INTELLIGENT UNDERGROUND ROBOTIC SYSTEM FOR URBAN ENVIRONMENTS
The European research project BADGER, coordinated by the Universidad Carlos III de Madrid (UC3M), has presented a prototype of an autonomous underground robot with intelligent navigation for urban environments.
WEAKNESS IS STRENGTH FOR THIS LOW-TEMPERATURE BATTERY
Nanoengineers at the University of California San Diego have discovered new fundamental insights for developing lithium metal batteries that perform well at ultra-low temperatures; mainly, that the weaker the electrolyte holds on to lithium ions, the better. By using such a weakly binding electrolyte, the researchers developed a lithium metal battery that can be repeatedly recharged at temperatures as low as -60 degrees Celsius—a first in the field.

RESEARCHERS PROVE FRAGMENTS OF SPLITTING ATOMIC NUCLEI BEGIN SPINNING AFTER SCISSION
A large international team of researchers has proven that fragments of splitting atomic nuclei begin spinning after scission occurs during nuclear fission. In their paper published in the journal Nature, the group describes their experiments, which may one day fully explain why such fragments begin spinning in the first place.
LIGHT UNBOUND: DATA LIMITS COULD VANISH WITH NEW OPTICAL ANTENNAS
Researchers at the University of California, Berkeley, have found a new way to harness properties of light waves that can radically increase the amount of data they carry. They demonstrated the emission of discrete twisting laser beams from antennas made up of concentric rings roughly equal to the diameter of a human hair, small enough to be placed on computer chips.
? EARTH NEWS?:
EVIDENCE SUGGESTS CLIMATE WHIPLASH MAY HAVE MORE EXTREMES IN STORE FOR CALIFORNIA
paleoclimatologists using pioneering research have uncovered evidence of ancient climate “whiplash” in California that exceeded even the extremes the state has weathered in the past decade. Their findings present a long-term picture of what regional climate change may look like in the state that supplies the U.S. with more than a third of its vegetables and two-thirds of its fruits and nuts.
GULF STREAM SYSTEM AT ITS WEAKEST IN OVER A MILLENNIUM
IN MORE THAN 1,000 YEARS, THE ATLANTIC MERIDIONAL
Overturning Circulation (AMOC), also known as Gulf Stream System, has not been as weak as in recent decades. This is the result of a new study by scientists from Ireland, Britain and Germany. The researchers compiled so-called proxy data, taken mainly from natural archives like ocean sediments or ice cores, reaching back many hundreds of years to reconstruct the flow history of the AMOC. They found consistent evidence that its slowdown in the 20th century is unprecedented in the past millennium; it is likely linked to human-caused climate change. The giant ocean circulation system is relevant for weather patterns in Europe and regional sea levels in the U.S.; its slowdown is also associated with an observed cold blob in the northern Atlantic.
? ASTRONOMY & SPACE NEWS??:
COMET MAKES A PIT STOP NEAR JUPITER’S ASTEROIDS
After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way. The object has settled near a family of captured ancient asteroids, called Trojans, that are orbiting the Sun alongside Jupiter. This is the first time a comet-like object has been spotted near the Trojan population.
TITAN’S ATMOSPHERE RECREATED IN AN EARTH LABORATORY
Beyond Earth, the general scientific consensus is that the best place to search for evidence of extraterrestrial life is Mars. However, it is by no means the only place. Aside from the many extrasolar planets that have been designated as “potentially-habitable,” there are plenty of other candidates right here in our solar system. These include the many icy satellites that are thought to have interior oceans that could harbor life.
? NANOTECHNOLOGY NEWS⛄☃:
TINY BUBBLE STUDY COULD IMPROVE DENTISTS’ TOOLS
People’s teeth-chattering experiences in the dentist’s chair could be improved by fresh insights into how tiny, powerful bubbles are formed by ultra-fast vibrations, a study suggests.
GRAPHENE FILTER MAKES CARBON CAPTURE MORE EFFICIENT AND CHEAPER
Chemical engineers at EPFL have developed a graphene filter for carbon capture that surpasses the efficiency of commercial capture technologies, and can reduce the cost carbon capture down to $30 per ton of carbon dioxide.
