Santa Clara takes over MetroFi network for meter reading: The city might also expand free public access. Advertisements will be removed as well as logins. This action is a far cry from the last time a firm said they were withdrawing from a wireless business that had spread nodes all over Santa Clara (that would be Metricom's Ricochet network). With Ricochet, users needed proprietary modems; with Wi-Fi, the city can turn the network to serve several purposes without worrying about public access adapters.
July 25: In science and technology, spheres of society where women are woefully underrepresented, this day in history offers a bountiful exception. Here are the milestones:
In 1865, "James Barry," the first woman physician in modern times, compelled to disguise herself as a man in order to practice her profession, dies.
In 1920, Rosalind Franklin, the unheralded co-discoverer of DNA, is born.
In 1978, Louise Joy Brown, the world's first test-tube baby, is born.
In 1984, cosmonaut Svetlana Savitskaya becomes the first woman to walk in space.
James Barry
Barry, whose actual identity remains unknown, was born somewhere around 1795. After finishing medical school (at the age of 13, and already in disguise), "James Barry" waited a few years before joining the British army in 1813, where "he" served with distinction in a number of colonial postings, including India, South Africa and Canada.
While in South Africa, Barry became the first doctor-surgeon in the British Empire to perform a Caesarean section in which both the mother and child survived. Prior to that, C-sections were generally performed only when the mother was dead or dying.
Barry rose to the rank of inspector general in the army, but also worked with the Royal Navy, while stationed in Malta and Corfu, to improve the harsh conditions for sailors at sea.
It wasn't until Barry died in 1865 that it was discovered at the autopsy that "he" was really a "she." Somehow, Barry had managed to conceal her actual sex (and to give birth to a child herself) for more than 40 years. She was also the first woman to receive a medical degree, although the dons had no idea they were handing their sheepskin to a woman.
The first woman to earn a medical degree when her sex was known was Elizabeth Blackwell, who received her diploma barely two months after Barry died.
Rosalind Franklin
In April 1962, three men -- James Watson, Francis Crick and Maurice Wilkins -- shared the Nobel Prize for their discovery a decade earlier of the structure of DNA. Rosalind Franklin, a chemist whose X-ray diffusion photographs of DNA molecules showed their essential structure and paved the way for the trio's work, received nothing.
The extent to which Franklin was dismissed by her peers varies in the telling, although it was real enough: In his memoir, Watson wrote unflatteringly of her and downplayed her role in the discovery. Wilkins, a colleague of Franklin's who disliked her feminist attitudes, was equally critical. He'd also provided Watson, without Franklin's knowledge, with her key photograph, which showed -- for the first time -- the double-helix shape that underlies the structure of DNA. The photograph caused Watson to remark later: "The instant I saw the picture, my mouth fell open and my pulse began to race."
Crick was far more gracious, crediting Franklin with having done "the key experimental work." He also said that Franklin's early critique of their theoretical work caused them to rethink things, helping to set them on the right path.
The most recent scholarship, a 2002 biography (Rosalind Franklin: The Dark Lady of DNA, by Brenda Maddox), paints Franklin neither as a feminist hero nor a spurned woman. Her role in helping to solve the mystery of DNA is unquestioned, and her place in science history is secure.
Unhappily, Franklin died of cancer in 1958, only 37 years old. This has been cited as the reason she was not included with the others: The Nobel Prize is not awarded posthumously.
Louise Joy Brown
Today is Brown's 30th birthday. Brown, a British postal worker, is married and the mother of a 19-month-old boy. She is also the first person ever to be conceived by in vitro fertilization: the world's first test-tube baby.
Louise is the daughter of John and Lesley Brown, who had tried for nine years to conceive, before an infertility expert referred them to Patrick Steptoe, a gynecologist. Steptoe, working with physiologist Robert Edwards, had also been trying -- and failing -- to conceive a child since 1966. The difference, of course, is that Messrs. Steptoe and Edwards were hoping to conceive theirs in a laboratory petri dish. ("Test-tube baby" was a media invention, but as long as it's in glass, it's in vitro.)
They did succeed, however, in developing the method for fertilizing an egg outside a woman's body, which gave them hope.
Enter Lesley Brown, whose fallopian tubes were blocked, a condition that makes it impossible to become pregnant through sexual intercourse. Steptoe surgically removed an egg from one of her ovaries on Nov. 10, 1977, fertilized it in his laboratory and returned two nights later (after a dinner party for his wife's birthday) to find that the egg had evolved into an eight-cell embryo.
Steptoe implanted the embryo into Lesley Brown's uterus and hoped for the best. For nearly four years, every attempt at in vitro fertilization had failed, a fact the physicians didn't bother mentioning to the Browns during their interview. But in December, they were able to confirm that their patient was pregnant.
The most difficult part of Lesley Brown's pregnancy was dealing with the British tabloid press, which hounded the prospective mother and father unmercifully until the Browns wised up and sold the exclusive rights to their story to one of the jackals.
Louise Joy Brown was delivered by Caesarean section at 11:47 p.m. July 25. She weighed 5 pounds, 12 ounces: small, but not exceptionally so. As Steptoe described it: "I laid her down, all pink and furious, and saw at once that she was externally perfect and beautiful."
Steptoe died when Louise was 10, but Edwards attended her wedding. She told the Daily Mail earlier this month, "It's nice to have a close relationship. He's like a granddad to me."
Svetlana Savitskaya
Cosmonaut Savitskaya carried on the socialist egalitarian tradition by becoming the first woman to walk in space. She accomplished this while serving as flight engineer aboard the Soyuz T-12 mission to the Salyut 7 space station. Her EVA, or extravehicular activity, came 19 years after cosmonaut Alexei Leonov became the first person to leave an orbiting spacecraft, and she beat American astronaut Kathryn Sullivan out the door by three months.
Comrade Savitskaya was, simply, born to be a cosmonaut. Her father was a fighter pilot during World War II, later becoming deputy commander of the Soviet Air Defense, and was twice named a Hero of the Soviet Union. Without her father's knowledge, Savitskaya, who took an avid interest in flying from childhood, learned to parachute. She made 450 jumps by her 17th birthday.
She applied to pilot school at age 16, but was rejected because of her age. At 17, after jumping from 46,750 feet and free-falling more than eight miles before deploying her chute -- a record at the time -- Savitskaya began training as a pilot. By the time she was 24, Savitskaya was licensed to fly 20 different types of aircraft, including the MiG-21, which she piloted to a speed of 1,667 mph.
Savitskaya became a cosmonaut in 1980 and was the second woman to go into space, preceded only by fellow cosmonaut Valentina Tereshkova.
Savitskaya was accompanied in her 1984 EVA by cosmonaut Vladimir Dzhanibekov. The pair performed external experiments on the Salyut station and remained outside their Soyuz capsule for more than three-and-a-half hours.
Following her return, Savitskaya was selected to command an all-female Soyuz crew for a visit to Salyut 7, in observance of National Women's Day. The mission had to be scrubbed, however, because of problems aboard the space station.
