Physicists confirm possible discovery of fifth force of nature
Physicists confirm possible discovery of fifth force of nature by University of California, Irvine "If confirmed by further experiments, this discovery of a possible fifth force would completely change our understanding of the universe," says UCI professor of physics & astronomy Jonathan Feng, including what holds together galaxies such as this spiral one, called NGC 6814.

Researchers show that an iron bar is capable of decision-making
Researchers show that an iron bar is capable of decision-making by Lisa Zyga , Phys.org In tug-of-war dynamics, an iron bar can decide which slot machine has the higher winning probability by moving to the left for each rewarded play and to the right for each non-rewarded play of Machine A. The bar’s movements are caused by physical fluctuations. Credit: Kim, et al. (Phys.org)—Decision-making—the
Counting people with WiFi
An example of the setup (left) in an outdoor setting and (right) in an indoor setting. In each case, the received power measurements of a WiFi card (RSSI) are used to estimate the total number of people. Note that the robots are merely carrying the cards in this project. The TX is a D-link WBR1310 wireless router and the RX is an Atheros ar5006x WiFi card. Researchers in UC Santa Barbara professor
No Big Bang? Quantum equation predicts universe has no beginning
No Big Bang? Quantum equation predicts universe has no beginning by Lisa Zyga , Phys.org This is an artist's concept of the metric expansion of space, where space (including hypothetical non-observable portions of the universe) is represented at each time by the circular sections. Note on the left the dramatic expansion (not to scale) occurring in the inflationary epoch, and at the center the expa
