British scientists claim major advance in TB treatment
A team of British scientists have made a major breakthrough in the treatment and diagnosis of tuberculosis. Researchers in Birmingham and Oxford have been able to use genome sequencing to isolate different strains of the disease, which means patients who might have waited months to get the right drugs can now be diagnosed in little more than a week. Public Health England said it is the first time the technique has been used on this scale anywhere in the world.
Science says: Who and what is to blame for cancer?
About two-thirds of the mutations that occur in various forms of cancer are due to those random copying errors, researchers at Johns Hopkins University reported Thursday in the journal Science. It takes multiple mutations to turn cells into tumors _ and a lot of cancer is preventable, the Hopkins team stressed, if people take proven protective steps. Whatever the ultimate number, the research offers a peek at how cancer may begin.
Climate change: At 37 degrees, March 23 hottest day in seven years in Delhi
This year's March 23 has broken the last six years' hottest day record. Forecasting similar weather the following day, he added that there would be clear sky on Friday with maximum and minimum temperatures to be expected around 37 and 19 degrees Celsius, respectively. Wednesday's maximum temperature settled at 35.7 degrees Celsius, five degrees above the season's average, while the minimum temperature was recorded at 18.2 degrees Celsius, a notch above the season's average.
Arctic, Antarctica sea ice sinks to record low this year
Sea ice at both Arctic and Antarctica have sinked to a record low this year scientists have said. In February this year, the combined Arctic and Antarctic sea ice extent was at its lowest point since satellites began to continuously measure sea ice in 1979, said scientists at NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. The ice floating on top of the Arctic Ocean and surrounding seas shrinks in a seasonal cycle from mid-March until mid-September.
Europa: Our best shot at finding alien life?
From a distance, Europa appears to be etched with a nexus of dark streaks, like the product of a toddler's chaotic scribbling. The stresses that created Europa's smashed up terrain are best explained by the ice shell floating on an ocean of liquid water. While water is one vital prerequisite for life, Europa's ocean might have others - such as a source of chemical energy for microbes.
Artificial photosynthesis steps into the light
Finding a clean renewable source of hydrogen fuel is the focus of extensive research, but the technology has not yet been commercialized. Whitmire said the catalyst is grown from a molecular precursor designed to produce it upon decomposition, and the process is scalable. The Rice lab combined iron, manganese and phosphorus (FeMnP) into a molecule that converts to a gas when vacuum is applied. When this gas encounters a hot surface via CVD, it decomposes to coat a surface with the FeMnP catalyst.
Analysis: Building a market for renewable thermal technologies
A new Yale-led study analyzes the market potential of this technology across the state and provides key insights into spurring consumer demand. Renewable thermal technologies comprise a range of products-from solar water heaters to district energy systems-all designed to use renewable energy in the cooling of space and the heating of both space and water. Collectively, the use of energy for thermal purposes accounts for roughly one-third of all US energy consumption.
Big-game jitters: Coyotes no match for wolves' hunting prowess
Eastern wolves once roamed forests along the Atlantic coast, preying on moose, white-tailed deer and other hooved mammals collectively known as ungulates. The findings help resolve long-standing questions about whether eastern coyotes have filled the ecological niche left vacant when the eastern wolf became threatened, Benson said. Wolves rely on large prey to survive, said Benson, assistant professor of vertebrate ecology who conducted the research as a doctoral student at Trent University.
Team refines filters for greener natural gas
Natural gas producers want to draw all the methane they can from a well while sequestering as much carbon dioxide as possible, and could use filters that optimize either carbon capture or methane flow. No single filter will do both, but thanks to Rice University scientists, they now know how to fine-tune sorbents for their needs. The ratio of KOH to polymer during processing turned out to be the critical factor in determining the final filter's characteristics.
Protecting web users' privacy
Some travel sites have been known to jack up the prices on flights whose routes are drawing an unusually high volume of queries. The system is called Splinter because it splits a query up and distributes it across copies of the same database on multiple servers. The servers return results that make sense only when recombined according to a procedure that the user alone knows. When people were searching for certain kinds of patents, they gave away the research they were working on.
Live sports broadcasting in US braces for disruption
The business of live sports, seen as perhaps the last great firewall for traditional US broadcasters, is facing deepening challenges in the era of mobile and live streaming options. Twitter chief operating officer Anthony Noto said those live streams helped the NFL reach a younger and more international audience. He warned against giving away valuable sports content and pointed to what happened to the music industry-where digital content eroded profitability.
Kaikoura: 'Most complex quake ever studied'
The big earthquake that struck New Zealand last year may have been the most complex ever, say scientists. Subsequent investigations have found that at least 12 separate faults broke during the quake, including some that had not previously been mapped. At issue was the way the quake was able to rupture so far along its path, to produce such a big magnitude. Hundreds of people in the town of Kaikoura itself did though have to be evacuated because landslides had cut local roads.
NASA sees formation of Tropical Cyclone Caleb near Cocos Island
Shortly after Tropical Cyclone Caleb formed east of Cocos Island, NASA-NOAA's Suomi NPP satellite and NASA's Aqua satellite passed overhead gathering visible and infrared data on the twelfth tropical cyclone of the Southern Indian Ocean season. On March 23 at 0700 UTC the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite provided a visible image of Caleb.
NASA Participates in the NOAA GOES-16 Field Campaign
NOAA's GOES-16 satellite is ready to embark on another major milestone- The GOES-16 Field Campaign. During a three month long event, a combination of NOAA and NASA planes, sensors and satellites will fine-tune GOES-16's brand new instruments. GOES-16 is now observing the planet from an equatorial view approximately 22,300 miles above the surface of the Earth. All of the GOES-16 Field Campaign information will be permanently stored as reference data at NOAA's National Centers for Environmental Information.
Mathematical framework explains diverse plant stem forms
It is well known that as plants grow, their stems and shoots respond to outside signals like light and gravity. Using simple mathematical ideas, researchers from the Harvard John A Paulson School of Engineering and Applied Sciences (SEAS) constructed a framework that explains and quantifies the different shapes of plant stems. By accounting for these factors, we can explain the range of shapes seen in nature without the need for complex growth strategies.
Researchers make flexible glass for tiny medical devices
Brigham Young University researchers have developed new glass technology that could add a new level of flexibility to the microscopic world of medical devices. Led by electrical engineering professor Aaron Hawkins, the researchers have found a way to make the normally brittle material of glass bend and flex. The research opens up the ability to create a new family of lab-on-a-chip devices based on flexing glass. If you keep the movements to the nanoscale, glass can still snap back into shape, Hawkins said.
NASA examines Peru's deadly rainfall
Recently the GPM core observatory measured the heavy rainfall that caused extensive flooding and loss of life in Peru. An El Nino-like condition with warm ocean waters developed near Peru's coast. This extremely warm water off Peru's western coast has been blamed for promoting the development of these storms. These extreme rainfall rates were found in the line of storms extending southwestward from Peru's coast. The animation showed rainfall rates between 25 mm (~1 inch) and 50 mm (~2 inches) per hour in many storms.
Expedition 50 astronauts gears up for Friday spacewalk outside space station
Expedition 50 astronauts will conduct spacewalk outside the International Space Station (ISS) on Friday, March 24 to prepare for the future arrival of US commercial crew spacecraft and upgrade station hardware. The spacewalk will be performed by Expedition 50 Commander Shane Kimbrough of NASA and Flight Engineer Thomas Pesquet of European Space Agency (ESA). According to NASA, the spacewalk will prepare the Pressurized Mating Adapter-3 (PMA-3) for installation of the second International Docking Adapter, which will accommodate commercial crew vehicle dockings.
Hubble detects supermassive black hole kicked out of galactic core
This is the first time that astronomers found a supermassive black hole at such a large distance from its host galaxy centre. Now astronomers using the NASA/ESA Hubble Space Telescope have detected a supermassive black hole, with a mass of one billion times the Sun's, being kicked out of its parent galaxy. When the two black holes finally merged, the anisotropic emission of gravitational waves generated a kick that shot the resulting black hole out of the galactic centre.
Senate votes to undo privacy rules that protect user data
They said broadband providers would have to operate under tougher privacy requirements than digital-advertising behemoths like Google and Facebook. Jeff Flake, R-Ariz., said undoing the rules won't change existing consumer privacy protections. Democrats and consumer advocates say it will be easier for phone and cable companies to use and sell customer data. The House and President Donald Trump must still approve rolling back the privacy rules.
