'Google Inc. is designing tiny magnetic particles to patrol the human body for signs of cancer and other diseases, in the latest example of the Internet giant's sweeping ambition.
Google said its nanoparticles, less than one-thousandth the width of a red blood cell, would seek out and attach themselves to cells, proteins or other molecules inside the body. The company also is working on a wearable device with a magnet to attract and count the particles, as a monitoring tool.
The goal is to provide an early warning system for cancer and other diseases, with an eye toward more effective treatment.
"Every test you ever go to the doctor for will be done through this system," said Andrew Conrad, head of the Life Sciences team at the Google X research lab, who disclosed the project on Tuesday at The Wall Street Journal's WSJD Live conference. "That is our dream."'
'31 Egyptian Soldiers Are Killed as Militants Attack in Sinai'
'Cairo has raised the idea of a building an eight-mile barrier along its border with Gaza to deter Islamist terrorists from moving in and out of the Palestinian territory.
The terrorists are believed to be crossing via terror tunnels, even though Egypt has reportedly destroyed more than 1,800 underground passages in a bid to clamp down on Hamas and other terror groups operating there.
'The missteps and delays in diagnosis of the Liberian man prompted some states to impose or consider restrictions on travelers coming from the West African countries where the virus has killed nearly 5,000 people.
Responding to concerns that mandatory quarantine would inhibit doctors and nurses from traveling to West Africa, Cuomo said New York wanted to encourage personnel to go, lauding their "valor" and "compassion," while also protecting public safety at home.
"These people are extraordinary for their valor and their courage and their compassion," Cuomo said. "Anything we can do to encourage it, we want to do."
He added that New York was not changing the policy announced on Friday.
'After weeks of protests that have shaken this financial hub of 7.2 million people, residents thought they had seen it all. Then, on Tuesday night, something even more extraordinary happened, on live television: a polite debate between earnest students wearing black "Freedom Now" T-shirts and top Hong Kong leaders over the future of democracy.
'Scientists have reconstructed the genome of a man who lived 45,000 years ago, by far the oldest genetic record ever obtained from modern humans. The research, published on Wednesday in the journal Nature, provided new clues to the expansion of modern humans from Africa about 60,000 years ago, when they moved into Europe and Asia.
And the genome, extracted from a fossil thighbone found in Siberia, added strong support to a provocative hypothesis: Early humans interbred with Neanderthals.
'A Palestinian driver plowed his car into a group of people waiting at a light rail station in northern Jerusalem on Wednesday, the police said, killing an Israeli baby and injuring eight other people. The driver was shot and seriously injured by police officers as he tried to flee, according to the police, in an episode that added to the escalating tensions in the city.'
"Nine people were injured, three seriously, including an American infant who died after sustaining critical injuries," he continued.
'McCaughey said future Ebola patients should be treated at the bio-containment centers in the way the two infected Dallas nurses are currently being treated.
She added that while the centers can currently only treat 11 patients at a time, expanding the capacity of those facilities would be easier than preparing hundreds of hospitals to treat Ebola.
The Washington Post also reported early Tuesday that at least six African-American witnesses back Wilson's account of the shooting -- that he was attacked by Brown. This challenges earlier accounts that suggested that most black witnesses to the shooting said that Brown was shot for seemingly no reason at all while he had his hands raised.
'The man who gunned down a Canadian soldier at the National War Memorial in Ottawa on Wednesday was a convert to Islam who had already been designated "high-risk" by authorities.
that all travelers arriving in the U.S. from the three Ebola-stricken
African countries will be subject to a 21-day monitoring program.
The new rules apply to anyone returning from Liberia, Sierra Leone and
Guinea -- not just those who hold passports from those nations. This
would include American journalists, health care workers and travelers.
Returning travelers will have to give authorities an address, two
phone numbers and two email addresses, as well as the address and
contact of a personal contact. They will be required to take their
temperatures once per day and report to public health authorities, for
It took three days, during which time nine medical staff nursing him became infected, before Ebola was diagnosed and he was placed in isolation. He died two days later.
'Syrian rebels have overtaken a joint Russian-Syrian secret facility that they claim was a covert intelligence collection base. Opposition fighters say the post was used to snoop in on the communications of opposition groups -- and perhaps even the nearby Israelis.
Technologies like this allow us to imagine a new form of quarantine. Rather than relying on primitive instruments, indiscriminate profiling or questionnaires, we should consider running a pilot program to test asymptomatic travelers using sensitive P.C.R.-based techniques. Obviously, such technologies are expensive, but the cost is not prohibitive. A typical P.C.R. reaction, including labor, costs between $60 and $200 (we have already spent 100 times more disposing of the contaminated sheets from the home Mr. Duncan stayed in). Since the test takes about a third of the time of a trans-Atlantic flight, the flight would become the quarantine.
Huge logistical questions would need to be solved. Where would such a screening test be administered — before departure from West Africa, or upon landing? Could we imagine a walking quarantine in which travelers were granted provisional entry, but recalled if they tested positive? What infection precautions would need to be in place for such testing? What forms of consent would be required? Who would bear the costs? Who exactly would be tested?'
'Duke University researchers have made fluorescent molecules emit photons of light 1,000 times faster than with previous designs — a speed record, and a step toward realizing superfast light-emitting diodes (LEDs) for nanophotonic devices, such as telecommunication lasers and as single-photon sources for quantum cryptography.
So the Court officially gave no hint as to how it would rule when—or, as of today if—the same-sex-marriage issue comes before it. Unofficially, I don't see how that can be true. I don't see how today's decision doesn't signal that even within the Court, the fight is over.
'A new study published in the Cell Press journal Current Biology on October 2 could rewrite the story of ape and human brain evolution. While the neocortex of the brain has been called "the crowning achievement of evolution and the biological substrate of human mental prowess," newly reported evolutionary rate comparisons show that the cerebellum expanded up to six times faster than anticipated throughout the evolution of apes, including humans.
Portman has called for "active screenings" at U.S. ports of entry so that all passengers from countries with known outbreaks of Ebola are questioned as they arrive. Just as incoming international passengers are now asked where they have been, whether they are bringing in fruits or vegetables or have been in contact with livestock, travelers from West Africa would be asked if they were in contact with someone with Ebola or someone displaying symptoms of Ebola, or if they demonstrated any symptoms.
White House officials aren't saying what their rules might ultimately require. But the previous administration proposed giving the federal government the authority to order a "provisional quarantine" of three business days — or up to six calendar days — for those suspected of having swine flu or other illnesses listed in a presidential executive order.
The Bush-era proposal would also have required airlines and cruise lines to store more information about domestic and international passengers, such as e-mail addresses, traveling companions and return flight information. The information would be subject to review by federal officials in a health emergency, though it would be voluntary for passengers to provide the data….
"Particularly for flu, the disease is transmitted very rapidly. Within a few days, it's all over the place," Nuzzo said.'
Two direct final rules were published on December 26, 2012, that amend the Interstate and Foreign Quarantine Regulations...
The updates enhance definitions related to control of communicable diseases and use current medical terminology where appropriate. The final rules are the first step in helping modernize the federal quarantine regulations.
The problem is that we have pretty good evidence that black holes do
exist. If they don't exist then we have some explaining to do.
Years ago I saw how a few scientific dissenters theorized that black
holes were really just neutron stars, which is kind of like "black
hole-lite". However neutron stars couldn't account for the evidence
of billion solar mass black holes at the center of every galaxy.
