In 1947, Edwin H. Land first demonstrated his Polaroid Land camera, the first used self-developing film, at a meeting of the Optical Society of America at the Hotel Pennsylvania, New York City. It produced a black-and-white photograph in 60 seconds, using developer and fixer chemicals sandwiched in pods with the photographic paper and film. After exposure, developing was initiated by turning a knob that squeezed open the pod of chemicals.

In 1630, popcorn was introduced to the English colonists by an Indian named Quadequina who brought it in deerskin bags as his contribution at their first Thanksgiving dinner. Popcorn is a type of corn with smaller kernels than regular corn, and when heated over a flame, it "pops" into the snack we know it as today. Native Americans were growing it for more than a thousand years before the arrival of European explorers. In 1964, scientists digging in southern Mexico found a small cob of popcorn discovered to be 7,000 years old. Today, the United States grows nearly all of the world's popcorn.

It turns out that the six wheeled Opportunity unknowingly ‘created’ the mystery herself when she drove over a larger rock, crushing it with the force from the wheels and her 400 pound (185 kg) mass.

The largest clinical study ever conducted to date of patients with advanced leukemia found that 88 percent achieved complete remissions after being treated with genetically modified versions of their own immune cells.

Adult B cell acute lymphoblastic leukemia (B-ALL), a type of blood cancer that develops in B cells, is difficult to treat because the majority of patients relapse.

Patients with relapsed B-ALL have few treatment options; only 30 percent respond to salvage chemotherapy.

Saccharin discovered

In 1879, saccharin, the artificial sweetener, was discovered by Constantin Fahlberg, while he was researching coal tar compounds for Ira Remsen at Johns Hopkins University in Baltimore, Maryland With hands unwashed since leaving his laboratory work, during a meal, he accidentally discovered its intensely sweet taste when his fingers touched his lips. He subsequently obtained patents on its synthesis, and with his uncle, Dr. Adolf List, started a factory to produce and market it.

Soviet spacecraft reaches Venus surface

In 1966, the mission of the Soviet Union's unmanned spacecraft Venera 3 (Venus 3) was a partial success when it reached Venus and automatically released a small landing capsule intended to explore the planet's atmosphere during a parachute descent. However, contact had been lost since 16 Feb 1966. Although no data was returned before the capsule impacted, it became the first man-made object to touch the surface of another planet. The Soviet Union issued a commemorative stamp to mark the achievement. Venera 3 was launched on 16 Nov 1965. The landing capsule (0.9-m diam., about 300-kg) had been designed to collect data on pressure, temperature, and composition of the Venusian atmosphere. Failure is believed due to overheating of internal components and the solar panels

The reverse drive validated feasibility of a technique developed with testing on Earth to lessen damage to Curiosity's wheels when driving over terrain studded with sharp rocks.

On Tuesday, Feb. 18, the rover covered 329 feet (100.3 meters), the mission's first long trek that used reverse driving and its farthest one-day advance of any kind in more than three months.

The mission's destinations remain the same: a science waypoint first and then the long-term goal of investigating the lower slopes of Mount Sharp, where water-related minerals have been detected from orbit.

The Kepler Space Telescope has been inactive since May of 2013, but the probe's data has led astronomer's to discover 715 new planets

The 715 new planets are said to be distributed among 305 different star systems, and the number of Earth-sized planets increased by 400%

four of the newly discovered planets are about 2.5 times wider than Earth
