The first Nobel Prizes are awarded in Stockholm, Sweden, in the fields of physics, chemistry, medicine, literature, and peace. The ceremony came on the fifth anniversary of the death of Alfred Nobel, the Swedish inventor of dynamite and other high explosives. In his will, Nobel directed that the bulk of his vast fortune be placed in a fund in which the interest would be “annually distributed in the form of prizes to those who, during the preceding year, shall have conferred the greatest benefit on mankind.” Although Nobel offered no public reason for his creation of the prizes, it is widely believed that he did so out of moral regret over the increasingly lethal uses of his inventions in war.

Alfred Bernhard Nobel was born in Stockholm in 1833, and four years later his family moved to Russia. His father ran a successful St. Petersburg factory that built explosive mines and other military equipment. Educated in Russia, Paris, and the United States, Alfred Nobel proved a brilliant chemist. When his father’s business faltered after the end of the Crimean War, Nobel returned to Sweden and set up a laboratory to experiment with explosives. In 1863, he invented a way to control the detonation of nitroglycerin, a highly volatile liquid that had been recently discovered but was previously regarded as too dangerous for use. Two years later, Nobel invented the blasting cap, an improved detonator that inaugurated the modern use of high explosives. Previously, the most dependable explosive was black powder, a form of gunpowder.

Nitroglycerin remained dangerous, however, and in 1864 Nobel’s nitroglycerin factory blew up, killing his younger brother and several other people. Searching for a safer explosive, Nobel discovered in 1867 that the combination of nitroglycerin and a porous substance called kieselguhr produced a highly explosive mixture that was much safer to handle and use. Nobel christened his invention “dynamite,” for the Greek word dynamis, meaning “power.” Securing patents on dynamite, Nobel acquired a fortune as humanity put his invention to use in construction and warfare.

In 1875, Nobel created a more powerful form of dynamite, blasting gelatin, and in 1887 introduced ballistite, a smokeless nitroglycerin powder. Around that time, one of Nobel’s brothers died in France, and French newspapers printed obituaries in which they mistook him for Alfred. One headline read, “The merchant of death is dead.” Alfred Nobel in fact had pacifist tendencies and in his later years apparently developed strong misgivings about the impact of his inventions on the world. After he died in San Remo, Italy, on December 10, 1896, the majority of his estate went toward the creation of prizes to be given annually in the fields of physics, chemistry, medicine, literature, and peace. The portion of his will establishing the Nobel Peace Prize read, “[one award shall be given] to the person who has done the most or best work for fraternity among nations, for the abolition or reduction of standing armies, and for the holding and promotion of peace congresses.” Exactly five years after his death, the first Nobel awards were presented.

Today, the Nobel Prizes are regarded as the most prestigious awards in the world in their various fields. Notable winners have included Marie Curie, Theodore Roosevelt, Albert Einstein, George Bernard Shaw, Winston Churchill, Ernest Hemingway, Martin Luther King, Jr., the Dalai Lama, Mikhail Gorbachev, and Nelson Mandela. Multiple leaders and organizations sometimes receive the Nobel Peace Prize, and multiple researchers often share the scientific awards for their joint discoveries. In 1968, a Nobel Memorial Prize in Economic Science was established by the Swedish national bank, Sveriges Riksbank, and first awarded in 1969.

The Royal Swedish Academy of Sciences decides the prizes in physics, chemistry, and economic science; the Swedish Royal Caroline Medico-Surgical Institute determines the physiology or medicine award; the Swedish Academy chooses literature; and a committee elected by the Norwegian parliament awards the peace prize. The Nobel Prizes are still presented annually on December 10, the anniversary of Nobel’s death. In 2006, each Nobel Prize carried a cash prize of nearly $1,400,000 and recipients also received a gold medal, as is the tradition

HealthTap wants to make online health care more trustworthy
The sad fact is that most sources of health care advice online are sorely lacking in reliability. People with potential health issues are usually stuck wading through a wide array of potential diagnoses for their symptoms which may or may not have been fact-checked by an actual doctor. HealthTap says it can change this perception with a service that verifies the credentials of physicians and incentivizes doctors to participate by enhancing their reputations.

CICADA gliding UAV is designed to deploy sensors behind enemy lines
When soldiers want to gather intelligence in enemy territory, they often have to travel into high risk territory themselves, depositing acoustic, magnetic, chemical/biological or signals intelligence sensors by hand. Not only does this place the soldiers in harm’s way, but the logistics of such missions can also end up being quite costly. That’s why the U.S. Naval Research Laboratory Vehicle Research Section created the CICADA unmanned air vehicle (UAV). The tiny sensor-equipped glider was successfully tested at Arizona’s Yuma Proving Grounds on September 1st.

At the Wake Forest Institute for Regenerative Medicine, Dr. Anthony Atala’s lab is the largest in the world “manufacturing” body parts. We’re not talking about prosthetics here, and not robotics – this is growing new, living organs – and they are yours – made up of identical tissue found in the rest of your body. Growing a finger from the ground up: layering cartilage, bone, then muscle. A beating, engineered heart valve that’s learning how to pump blood before it’s implanted. It’s regenerative medicine and the goal is to help the tens of thousands of people worldwide waiting for organ transplants. In Pittsburgh, Dr. Steven Badylak has discovered a compound that tricks the body into repairing itself, much like the body knows how to do when it’s in the womb. The U.S. military has invested $250 million in regenerative research aimed at helping soldiers with severe battle injuries, regrowing muscle and skin for burn injuries, as well as transplant technology for lost limbs.
