FLORIDA: Scientists have caught a female python in Florida Everglades that was more than 17 feet long, weighed 140 pounds and contained 73 developing eggs.
The snake is the largest python ever removed from Big Cypress National Preserve, a 729,000-acre expanse of swampland west of Miami in South Florida, according to a statement.
Facebook statement on the Big Cypress National Preserve’s says, “using male pythons with radio transmitters allows the team to track the male to locate breeding females. The team not only removes the invasive snakes, but collects data for research, develop new removal tools, and learn how the pythons are using the Preserve.
The team tracked one of the sentinel males with the transmitter and found this massive female nearby.”
SEATTLE: A man in London has become the second person to be free of the AIDS virus after a stem cell transplant, Associated Press reported doctors as saying.
Until now, Timothy Ray Brown from the US was the only person believed to have been cured of HIV after undergoing a transplant in Berlin 12 years ago.
The latest case “shows the cure of Timothy Brown was not a fluke and can be recreated,” said Dr Keith Jerome of Fred Hutchinson Cancer Research Centre in Seattle.
The transplant changed the London patient’s immune system, giving him the donor’s mutation and HIV resistance. The patient voluntarily stopped taking HIV drugs to see if the virus would come back. There is no trace of the virus after 18 months off the drugs, says the report.

HONOLULU: Good news for aspiring satirists: Scientific analysis of real and joke headlines has uncovered a hack for writing witty one-liners.
To identify the secret ingredients of satire, researchers compared farcical headlines with nearly identical, but unfunny headlines. The investigation, presented January 31 at the AAAI Conference on Artificial Intelligence, revealed a strategy for changing words in serious statements to make them satirical. The technique could help AI write its own jokes or distinguish satire from fake news (SN: 8/4/18, p. 22).
The researchers compiled a dataset of satirical and serious headlines using the online game Unfun.me, where players edit humorous headlines from the satirical publication The Onion as little as possible to make them serious. These tweaks “put a finger onto the exact switch that induces the humor,” says Robert West, a computer scientist École Polytechnique Fédérale de Lausanne in Switzerland. He and coauthor Eric Horvitz, director of Microsoft Research in Redmond, Wash., amassed about 2,800 serious versions of nearly 1,200 headlines.
Most of the joke headlines followed a common logical structure, which West and Horvitz call “false analogy.” Words switched between spoof and serious headlines share a crucial similarity, as well as a fundamental difference.
Consider the humorless headline “BP ready to resume oil drilling” and its comedic counterpart “BP ready to resume oil spilling.” Subbing spilling for drilling works because both share the critical commonality of being activities famously associated with BP, but with one being intended and the other accidental. West and Horvitz identified several types of oppositions between words in serious and satirical headlines, such as modern versus outdated, human versus animal and obscene versus not.
These findings could help programmers create AI systems that better understand and have more natural interactions with humans, says Dan Goldwasser, an AI and natural language processing researcher at Purdue University in West Lafayette, Ind., not involved in the analysis. Other research on computational humor has focused on simply predicting whether a text is comical; a more fundamental knowledge of satire’s structure could help AI understand why something is funny and create humor of its own.
But the false analogy formula alone is not enough to build an AI that cranks out witticisms, Goldwasser says. Knowing what is and isn’t obscene, for example, requires a lot of common sense that AI generally doesn’t have yet.
The insights can also help humans try their hand at satire. After decoding the false analogy pattern, West used the sublime versus mundane opposition to transform the headline “2018 Bordeaux vintage benefits from outstanding grape harvest” into “2018 Pepsi vintage benefits from outstanding high-fructose corn harvest.”
Even for a human, “it’s still hard to make a headline that really punches,” West says. “But at least there is some recipe now.”

NEW DELHI- The Indian Space Research Organisation (ISRO) is all set to launch Thursday night two satellites Kalamsat and Microsat-R, officials said. The satellites would be launched through Polar Satellite Launch Vehicle (PSLV) in its 46th flight from Satish Dhawan Space Centre (SDSC) in Sriharikota, off the Bay of Bengal coast located in southern Indian state of Andhra Pradesh.
“Countdown for the launch of PSLVC44 started yesterday at 7:37 p.m. local time at Satish Dhawan Space Centre, Sriharikota. The launch is scheduled today at 11:37 p.m. local time,” a statement issued by ISRO said.
Kalamsat is a payload developed by students from Space Kidz India, while as Microsat-R is an imaging satellite meant for the Defence Research and Development Organisation (DRDO) purposes. Reports said the Kalamsat is a 10 cm cube nano satellite weighing about 1.2 kg and has a life span of about two months, however, Microsat-R is a 740-kg military imaging satellite.
