Tropical Storm Raymond moved away from western Mexico and into warmer waters with less wind shear over the weekend of Oct. 26-27, where it strengthened into a hurricane again. NASA's Aqua satellite captured an eye-opening image of Raymond before it ran into strong wind shear.
The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite captured a visible image of Hurricane Raymond that showed its eye had re-developed and opened after it re-strengthened in the Eastern Pacific. The image was taken on Oct. 27 at 21:15 UTC/5:15 p.m. EDT.
By Oct. 28, wind shear had again kicked up again and Raymond was weakening. Wind shear increased from the southwest pushing the strongest convection, and showers and thunderstorms northeast of the center.
An infrared, false-colored image of Hurricane Raymond was taken by the Atmospheric Infrared Sounder or AIRS instrument aboard NASA's Aqua satellite on Oct. 28 at 9:23 UTC/5:23 a.m. EDT. The AIRS infrared image showed that the strongest storms had been displaced to the northeast of the center as a result of southwesterly wind shear. Those strong storms were still showing cold cloud top temperatures in excess of -63F/-52C indicating they were high in the troposphere and had the potential to generate heavy rain.
At 11 a.m. EDT/1500 UTC, Hurricane Raymond's maximum sustained winds were near 85 mph/140 kph and weakening. The center of Hurricane Raymond was near latitude 16.4 north and longitude 117.0 west, about 645 miles/1,035 km southwest of the southern tip of Mexico's Baja California. Raymond was moving toward the north near 7 mph/11 kph and is expected to turn toward the north-northeast. Raymond is forecast to weaken to a tropical storm late on Oct. 28 and a depression later that day.
The National Hurricane Center noted on Oct. 28 that Raymond is moving into an area with stronger wind shear, cooler sea surface temperatures and drier air: three factors that will lead to its dissipation in the next couple of days.

It was the dawn of a new era in filmmaking, but “Star Wars” also had plenty of silly moments caught on film during production.
Harrison Ford, Mark Hamill, Carrie Fisher, Alec Guinness, and Peter Cushing all got caught up in their lines from time to time, and Lucasflim editor J.W. Rinzler compiled the footage into a fabulous blooper reel.
Possibly the funniest moment involves a legion of storm troopers who end up tripping as they try to walk through a hole blown in the wall of the space craft.
The lucky folks at July’s San Diego Comic-Con got a sneak peek at the new clip, and now it’s available to view below.

Gas and oil deposits in shale have no place to hide from an Oak Ridge National Laboratory technique that provides an inside look at pores and reveals structural information potentially vital to the nation's energy needs.
The research by scientists at the Department of Energy laboratory could clear the path to the more efficient extraction of gas and oil from shale, environmentally benign and efficient energy production from coal and perhaps viable carbon dioxide sequestration technologies, according to Yuri Melnichenko, an instrument scientist at ORNL's High Flux Isotope Reactor.
Melnichenko's broader work was emboldened by a collaboration with James Morris and Nidia Gallego, lead authors of a paper recently published in Journal of Materials Chemistry A and members of ORNL's Materials Science and Technology Division.
Researchers were able to describe a small-angle neutron scattering technique that, combined with electron microscopy and theory, can be used to examine the function of pore sizes.
Using their technique at the General Purpose SANS instrument at the High Flux Isotope Reactor, scientists showed there is significantly higher local structural order than previously believed in nanoporous carbons. This is important because it allows scientists to develop modeling methods based on local structure of carbon atoms. Researchers also probed distribution of adsorbed gas molecules at unprecedented smaller length scales, allowing them to devise models of the pores.
"We have recently developed efficient approaches to predict the effect of pore size on adsorption," Morris said. "However, these predictions need verification and the recent small-angle neutron experiments are ideal for this. The experiments also beg for further calculations, so there is much to be done."
While traditional methods provide general information about adsorption averaged over an entire sample, they do not provide insight into how pores of different sizes contribute to the total adsorption capacity of a material. Unlike absorption, a process involving the uptake of a gas or liquid in some bulk porous material, adsorption involves the adhesion of atoms, ions or molecules to a surface.
This research, in conjunction with previous work, allows scientists to analyze two-dimensional images to understand how local structures can affect the accessibility of shale pores to natural gas.
"Combined with atomic-level calculations, we demonstrated that local defects in the porous structure observed by microscopy provide stronger gas binding and facilitate its condensation into liquid in pores of optimal sub-nanometer size," Melnichenko said. "Our method provides a reliable tool for probing properties of sub- and super-critical fluids in natural and engineered porous materials with different structural properties.
"This is a crucial step toward predicting and designing materials with enhanced gas adsorption properties."
Together, the application of neutron scattering, electron microscopy and theory can lead to new design concepts for building novel nanoporous materials with properties tailored for the environment and energy storage-related technologies. These include capture and sequestration of man-made greenhouse gases, hydrogen storage, membrane gas separation, environmental remediation and catalysis.

HAIKOU, China (AP) — Tiger Woods issued a veiled challenge to Golf Channel over a column written by analyst Brandel Chamblee that a series of rules violations by Woods amounted to cheating.
Woods spoke publicly for the first time since Chamblee, a longtime critic of the world's No. 1 player, wrote a column for SI Golf Plus in which he gave Woods an "F'' for his season for being "a little cavalier" with the rules.
Chamblee is best known for his work with Golf Channel, though he also is a contributor to SI Golf Plus. He took to Twitter last week to apologize to Woods for "this incited discourse," though not for the content of his column.
"All I am going to say is that I know I am going forward," Woods said before his exhibition match with Rory McIlroy at Mission Hills. "But then, I don't know what the Golf Channel is going to do or not. But then that's up to them. The whole issue has been very disappointing as he didn't really apologize and he sort of reignited the whole situation.
"So the ball really is in the court of the Golf Channel and what they are prepared to do."
Golf Channel has not commented on the flap. Chamblee has said he was not asked to apologize by anyone.
Chamblee saved Woods for last in his report card of 14 players in a column posted Oct. 18 on Golf.com. He told of getting caught cheating on a math test in the fourth grade, and how the teacher crossed a line through his "100" and gave him an "F."
Chamblee followed that anecdote by writing, "I remember when we only talked about Tiger's golf. I miss those days. He won five times and contended in majors and won the Vardon Trophy and ... how shall we say this ... was a little cavalier with the rules." He then gave Woods a "100" with a line through it, followed by the "F."
In one of his tweets last week, Chamblee said he intended to point out Woods' rules infractions, "but comparing that to cheating in grade school went too far."
Woods' agent, Mark Steinberg, was so incensed by the column that he issued a statement to ESPN.com that raised the possibility of legal action. Steinberg shared his client's views.
"I'm all done talking about it and it's now in the hands of the Golf Channel," Steinberg said. "That's Tiger's view and that's mine, and all we want to do is move forward. And whether the Golf Channel moves forward as well, then we'll have to wait and see."
Woods accepted a two-shot penalty in Abu Dhabi for taking relief from an embedded ball in a sandy area covered with vegetation. Augusta National gave him a two-shot penalty for taking the wrong drop in the second round of the Masters. And the PGA Tour gave him a two-shot penalty after his second round of the BMW Championship when video evidence showed that his ball moved slightly from behind the first green. Even after watching the video, Woods insisted that his ball only oscillated.
Also in question — at least on Internet blogs — was the drop Woods took on the 14th hole of the TPC Sawgrass during the final round of The Players Championship. Woods checked with playing partner Casey Wittenberg on where to take the penalty drop, which is standard procedure. Wittenberg said it was the correct spot.
Chamblee said in an email last week to The Associated Press that he never said outright that he thinks Woods cheated, and that was by design.
"I think 'cavalier with the rules' allows for those with a dubious opinion of the BMW video," Chamblee said. "My teacher in the fourth grade did not have a dubious opinion of how I complete the test. But she was writing to one, and as I was writing to many, I felt it important to allow for the doubt some might have, so I chose my words accordingly.
"What people want to infer about that is up to them," he said. "I have my opinion, they can form theirs."
Chamblee has developed a reputation for being critical of Woods, mainly regarding his golf game. His column struck a nerve with many, however, because of the implication that three rules violations and a penalty drop involving Woods amounted to cheating — the strongest accusation possible in golf.
"What brought me here was the realization that my comments inflamed an audience on two sides of an issue," Chamblee wrote on Twitter when he apologized. "Golf is a gentleman's game and I'm not proud of this debate. I want to apologize to Tiger for this incited discourse."

In these smartphone-studded days, it's easy to forget how computers worked. Once you had to run programs off of floppy disks and wait ages for everything to load. Luckily for your nostalgia, some bored developers are keeping the past alive with full-featured emulators that run in your browser.
Teaming up for some promotional duties, Kate Bosworth and Michael Polish showed up at SiriusXM radio studios in New York City on Monday morning (October 28).
The “Blue Crush” babe and her handsome husband looked warm in winter coats as they made their way past fans and shutterbugs ahead of their on-air interview.
Kate just unveiled her brand new winter collection for the British high street retailer Topshop, and she can’t wait for her fans to try it on.
Described as “tailored and classic,” Bosworth’s duds are sure to please. “For fall, we wanted to create luxurious pieces with a strong minimalist approach.”
