It is known to every tug-of-war champion that the power to pull the rope doesn’t lie in arms, but in planting two feet firmly in the ground for leverage.
Now engineers at Stanford University applied this basic principle while they designed tiny robots, called as MicroTugs. These tiny robots have the ability to drag objects that are almost hundreds of times of their weight.
For example, a 9-gram of MicroTug can pull a 2.2-pound load vertically up glass. This will be equal to a human climbing a skyscraper while carrying an elephant.
On Monday, privately owned California-based company SpaceX’s unmanned rocket blasted off from Cape Canaveral Air Force Station in Florida.
The rocket carried the Spacebus 4000 telecommunications satellite known as TurkmenAlem52E built by Thales Alenia Space, a joint venture of Thales SA and Finmeccanica SpA.
Monday's launch was the 18th for SpaceX, which aimed to deliver the satellite owned and operated by the former Soviet republic of Turkmenistan. The satellite will give Turkmenistan its first foothold in space.
On Wednesday, officials said that a healthy sea lion pup that was sent back to the sea by deputies after waddling a quarter-mile onshore has been staying in the waves.
Mendocino County sheriff's Capt. Greg Van Patten said that so far they have received no reports of him running down the street or anything.
On Sunday, deputies, who were patrolling Highway 1, just south of Fort Bragg, spotted an animal moving slowly in dark, dense fog.
Hubble Space Telescope is celebrating its 25th anniversary this week. The space telescope was launched on April 24, 1990. With the help of four main scientific instruments, Hubble sees not only in visible light, but also in near ultraviolet and near infrared. Scientists have been able to gain insight into quasars, determine the age of universe and discover dark energy, with the courtesy of Hubble telescope.
To mark the 25th anniversary of Hubble Space Telescope, a documentary 'Hubble's Cosmic Journey' was premiered on April 20 on National Geographic Channel.
