Washington: Last May, as Ebola crept across West Africa, America's top infectious disease expert told a group of Harvard University students in a commencement speech to always second-guess their assumptions because "overconfidence can kill."
Five months later in a congressional hearing room, Tom Frieden was accused of not following his own advice repeatedly assuring the US it was safe from an Ebola outbreak even as two US nurses became infected and one was allowed to board a commercial airline, each following safety protocols Frieden helped put in place.
Washington - Obama administration officials said a Dallas health care worker who handled a lab specimen from a Liberian man who died from Ebola is self-quarantined on a Caribbean cruise ship and is being monitored for infection.
State Department spokeswoman Jen Psaki said in a statement Friday that the woman had shown no signs of the disease and has been asymptomatic for 19 days.
An administration official and another person familiar with the matter said the cruise ship, the Carnival Magic, had stopped in Belize but officials there would not allow the passenger to leave the vessel.
Washington, Oct 17 : A group of infectious disease experts have suggested that the conventional U. S. medical centers may not be able to put a stop to spread of Ebola and a national network of specialized containment and treatment facilities may be needed to reduce the virus' spread.
Washington, Oct 17 : A new study has found that undergraduates were 2 times more likely to have unprotected sex during "hookups."
Jonathan Marc Bearak from New York University explored the changes in undergraduate uncommitted sexual behavior during years 1-4 of college. The article provides reasoning for the decline in the use of condoms, and explains how changes in the odds of coitus and condom use depend on family background, school gender imbalance, and whether the partners attended the same college.
Washington, Oct 17 : Apple senior vice president of software engineering, Craig Federighi said that introducing Macbooks with touch screens is something Apple has no plans to do.
Federighi said that they don't think it's the right interface, honestly, Mac is sort of a sit-down experience.
He added that it's awkward and uncomfortable to sit at a desk and continuously reach forward to touch a computer screen. It's not like an iPad or iPhone that you hold in your hands and use in a very relaxed position, CNET reported.
Washington, Oct 17 : US Vice President Joe Biden's son, who was discharged this year from the US Navy after reportedly testing positive for cocaine, has expressed regret over his actions.
According to FOX News and as reported by the Wall Street Journal, junior Biden was discharged from duty in February this year because he failed a drug test after reporting to his unit at Navy Public Affairs Support Element East in Norfolk, Va.
Biden, 44, said that he was "embarrassed" and "deeply regretted" his actions that led to his administrative discharge.
Biden, who joined the military in 2013, said that it was the honour of his life to have served in the US Navy .
Washington, Oct 17 - Scientists using instruments aboard the Cassini spacecraft, have measured the wobbles of Mimas, the closest of Saturn's regular moons, and observed that the back and forth wobble caused a surface displacement of 6 kilometers.
Also they found that the amount of the to-and-fro motion indicated that Mimas' interior was not uniform and those wobbles could be produced if the moon contained a weirdly shaped, rocky core or if a sub-surface ocean exists beneath its icy shell.
The astronomy team used a technique called stereo-photogrammetry to interpret images taken by the Cassini Imaging Science Subsystem to measure the libration.
Washington, Oct 17 - Scientists have studied the mystery of 'nanoflares' that may be responsible for causing coronal heating in the Sun and these observations were used from the recently launched Interface Region Imaging Spectrograph (IRIS).
Washington, Oct 17 - The space telescope IRIS researchers have found evidence of such short-lived heat pockets in the Sun and showed that the temperature distribution within the Sun's outer layers could occasionally turn topsy turvy.
Researchers with the lead of the Max Planck Institute for Solar System Research (MPS) in Germany have received the data from NASA's space telescope IRIS (Interface Region Imaging Spectrograph).
Washington, Oct 17 - A new study has revealed that siblings uniquely promote sympathy and altruism in boys.
According to study, a hostile relationship with a sibling made boys more likely to have behavior problems and a quality relationship with a brother or sister also increased teens' levels of altruism, also known as prosocial behavior.
Washington, Oct 17 - A new space study detected mysterious dark matter-'axions' in the X-Ray sky.
As first author, Late Professor George Fraser from the University of Leicester had said that the dark matter was a kind of invisible mass of unknown origin that cannot be seen directly with telescopes, but was instead inferred from its gravitational effects on ordinary matter and on light.
Scientists also said that the dark matter was believed to make up 85% of the matter of the universe.
Washington, Oct 17 - NASA's Hubble Space Telescope has recently spotted a diminutive object that is estimated to be over 13 billion light-years away; this is supposed to be one of the farthest, faintest, and smallest galaxies ever seen.
Newark (US): Officials at airports in four American cities are scheduled to start taking the temperatures of passengers from three West African countries as part of a stepped up Ebola screening programme.
Federal health officials say the entry screenings that start today add another layer of protection to halt the spread of the Ebola.
Screeners will use no-touch thermometers to try to find passengers with fevers.
The screenings started at New York's Kennedy International Airport on Saturday. Screenings will now be conducted at Washington Dulles, Chicago O'Hare, Newark's Liberty and Hartsfield-Jackson in Atlanta.
Washington, Oct 16 : Scientists have confirmed that some peculiar ancient fossils are actually distant relatives of humans.
According to the University of Adelaide researchers, the fossils belong to 500-million-year-old blind water creatures which had alien-like in appearance, known to scientists as "vetulicolians."
More than 100 years since they were first discovered, these marine creatures were "filter-feeders" shaped like a figure-of-8.
Washington, Oct 16 : Scientists have discovered an " ice-giant" planet, similar to Uranus and Neptune, for the first time in a far away galaxy .
The international research team led by Radek Poleski, postdoctoral researcher at The Ohio State University, said that the newly discovered planet is so far away that they can't actually tell anything about its composition.
However, the astronomers said that its distance from its star suggests that it's an ice giant-and since the planet's orbit resembles that of Uranus, they are considering it to be a Uranus analog.
Washington, Oct 16 : Scientists have revealed that they may have developed a cheaper new way to effectively remove arsenic from water with the help of cigarette ash.
Jiaxing Li and colleagues explain that naturally occurring and industry-related arsenic contaminates groundwater at high levels in many countries, including Chile, China, Hungary and Mexico and the odorless, tasteless element can cause skin discoloration, stomach pain, partial paralysis and a range of other serious health problems.
Washington, Oct 16 - A top U.S. military official has reportedly said that the United States has a "winning strategy" to defeat the Islamic State (IS) and that he "can't foresee" sending large ground troops to Iraq.
General Martin Dempsey, the chairman of the U.S. Joint Chiefs of Staff, said that the U.S. has received a "significant commitment" from other members of the anti- IS coalition to add advisory teams. He added that the plan is to set up three bases where the U.S. and others can train Iraqi security forces along with Kurdish forces which are fighting the terror group on ground.
Washington, Oct 16 - A new study has provided a deeper insight into the long-running hunt for super-Earths orbiting into the space.
NASA's Kepler spacecraft, which had launched on a planet-hunting mission in 2009, searched one small patch of the sky and identified more than 4,000 candidate exoplanets-worlds orbiting stars other than our own Sun. It was the first survey to provide a definitive look at the relative frequency of planets as a function of size.
Washington: A senior US senator has welcomed the World Trade Organization's decision against India's ban on American poultry products, saying that the move would boost the country's export of poultry products to India.
"This is a great victory for the United States and Georgia poultry, in particular. I have been working to open up India to US poultry since this issue was brought to my attention," Senator Johny Isakson, ranking member on the Senate Finance Subcommittee on International Trade, said.
