Bad moon rising: Astronomers explain "full moon curse"

The full moon has long been associated with any number of superstitions. While links with lunacy, violence, fertility, disasters, and the stock market have been thoroughly debunked, the possibility of a causative role in some arenas still remains a possibility. A lunar ranging study carried out using reflectors has long contended with the "Full-Moon Curse," a near-total fading of reflected signals during the full Moon. This Curse is real, and has now been explained. Read More

Spitzer space telescope observations reveal expansion rate of the Universe

The size and age of our Universe is not only a critically important issue in cosmology, but is also among the most controversial and delicate of the cosmological questions. Infrared observations made using NASA's Spitzer Space Telescope have now given us the most precise estimate yet of the rate at which our Universe is expanding. The key was not the discovery of a new method for measuring distance. Rather, astronomers discovered how to measure brightness more accurately. The new value for the Hubble constant, good to within three percent, is 74.3 kilometers per second per megaparsec (km/s/Mpc). Read More

Wave Glider aquatic robots set world record

On November 17th of last year, a group of four wave-powered autonomous aquatic robots set out from San Francisco, embarking on a planned 37,000-mile (60,000-km) trip across the Pacific ocean. Recently, the fleet of Wave Gliders completed the first leg of their journey, arriving at Hawaii’s Big Island after traveling over 3,200 nautical miles (5,926 km). By doing so, they have set a new distance record for unmanned wave-powered vehicles – that record previously sat at 2,500 nautical miles (4,630 km). Read More

E-cyclist pedals over 1600km into record books

The CEO of Australia's Hahn Environmental Services, the largest producer of biodiesel in Queensland, has smashed the distance set by Guinness for the Longest Distance Traveled by Electric Bicycle in One Week. Riding a modified Stealth Bomber e-bike, which had its battery packs charged by a wind turbine sitting atop a Mini Moke running on green fuel, Allan Lear managed to pedal an amazing 1,629 km (1,012 miles) through Australia's outback - he is now waiting for the achievement to be verified by Guinness as a World Record.

Schluckspecht EV travels a world record 1,000 miles+ on a single charge

The “Schluckspecht E” electric vehicle built by a team at the University of Applied Sciences in Offenberg, Germany has broken the world record for the longest distance traveled on a single charge. The world record attempt was made at the Bosch test track in Boxberg with the vehicle traveling a total distance of 1631.5 km (1,013.76 miles), breaking the previous record of 1,003 km (623 miles) set by the Japan Electric Vehicle Club last year.

Ranger walking robot sets new world record at 1.34mph

It might not have been setting a cracking pace, but a Cornell University robot named Ranger set an unofficial world record on July 6 when it walked 14.3 miles in about 11 hours on a single charge. The untethered, four-legged robot was steered around the 1/8-mile indoor track in Cornell’s Barton Hall by a human operator using a standard toy remote control some 108.5 times. On its record setting journey Ranger made 65,185 steps, beating the former record for an untethered legged robot of 12.8 miles set by Boston Dynamics’ BigDog. Read More
