Strawberries protect the stomach from alcohol

In an experiment on rats, European researchers have proved that eating strawberries reduces the harm that alcohol can cause to the stomach mucous membrane. Published in the open access journal Plos One, the study may contribute to improving the treatment of stomach ulcers.

A team of Italian, Serbian and Spanish researchers has confirmed the protecting effect that strawberries have in a mammal stomach that has been damaged by alcohol. Scientists gave ethanol (ethyl alcohol) to laboratory rats and, according to the study published in the journal Plos One, have thus proved that the stomach mucous membrane of those that had previously eaten strawberry extract suffered less damage.

Sara Tulipani, researcher at the University of Barcelona (UB) and co-author of the study explains that "the positive effects of strawberries are not only linked to their antioxidant capacity and high content of phenolic compounds (anthocyans) but also to the fact that they activate the antioxidant defences and enzymes of the body."

The conclusions of the study state that a diet rich in strawberries can have a beneficial effect when it comes to preventing gastric illnesses that are related to the generation of free radicals or other reactive oxygen species. This fruit could slow down the formation of stomach ulcers in humans.

Gastritis or inflammation of the stomach mucous membrane is related to alcohol consumption but can also be caused by viral infections or by nonsteroidal anti-inflammatory medication (such as aspirin) or medication used to treat against the Helicobacter pylori bacteria.

Maurizio Battino, coordinator of the research group at the Marche Polytechnic University (UNIVPM, Italy) suggests that "in these cases, the consumption of strawberries during or after pathology could lessen stomach mucous membrane damage."

The team found less ulcerations in the stomachs of those rats which had eaten strawberry extract (40 milligrams/day per kilo of weight) for 10 days before being given alcohol.

Battino emphasises that "this study was not conceived as a way of mitigating the effects of getting drunk but rather as a way of discovering molecules in the stomach membrane that protect against the damaging effects of differing agents."

Treatments for ulcers and other gastric pathologies are currently in need of new protective medicines with antioxidant properties. The compounds found within strawberries could be the answer.

Young woman mysteriously ages overnight

Nguyen Thi Phuong from Vietnam is only 26, but you would be forgiven for mistaking her as an old woman.

After suffering an allergic reaction in 2008 and taking a variety of medications prescribed for it, Phuong's skin on her face, neck and hands rapidly wrinkled and became saggy, giving her the appearance of a 70-year-old granny.

It all began when the young lady from Giong Trom district of Ben Tre province ate some seafood.

It made her face break out into an itchy rash so bad, that she used to scratch her face even in sleep, Phuong told Tuoi Tre, a major Vietnamese daily newspaper where the news first broke.

To alleviate the symptoms, she ate some medication her husband, Nguyen Thanh Tuyen, 34, bought her.

The medications did not work. She then visited a local doctor, who prescribed her pills for dermatitis.

However, the pills made her face swell up and hives erupt on her skin. She stopped taking them after a week, and turned to some traditional Chinese medicine practitioners in town.

She was given some medication that reduced the swelling, but also made her put on weight. However, the medication was expensive, costing VND30,000 (S$1.88) a day, and did not do much to improve her condition.

Phuong soon began wearing a face mask whenever she went out. After her husband quit his job in 2009 to take care of her, they ran out of money and she stopped taking all medications.

She then decided it as a fate decreed by God and the couple stopped trying to cure her condition, Phuong told local news outlets.

Amber Miller said she was happy but called it the "longest day of my life" after giving birth to a daughter following completing the Chicago Marathon

Instead of having a rest after completing the Chicago Marathon, pregnant Amber Miller gave birth.

Mrs Miller, who was nearly 39 weeks pregnant, said "it was the longest day of my life". She gave birth to a healthy 7.7lb (3.5kg) girl, June.

The marathon was the eighth for the 27-year-old, who already had one child. On her doctor's orders she ran half and walked half the distance.

"Lots of people were cheering me on: 'Go pregnant lady'," she said.

"For me, it wasn't anything out of the ordinary. I was running up until that point anyway," she told Associated Press news agency.

"I am crazy about running."

Because she half-walked the race, she finished the 26.2 mile (42.16km) course in 6:25 - slower than her usual pace.

"A few minutes after finishing, the contractions became stronger than normal and I understood what was going on," she said.

"When they became more regular, we had a sandwich and then we left for hospital," Mrs Miller added.

Introduction to Artificial Intelligence
http://www.ai-class.com

Online Introduction to Artificial Intelligence is based on Stanford CS221, Introduction to Artificial Intelligence. This class introduces students to the basics of Artificial Intelligence, which includes machine learning, probabilistic reasoning, robotics, and natural language processing.

The objective of this class is to teach you modern AI. You learn about the basic techniques and tricks of the trade, at the same level we teach our Stanford students. We also aspire to excite you about the field of AI. Whether you are a seasoned professional, a college student, or a curious high school student - everyone can participate.

This online class will make this material available to a worldwide audience. But rather than just watching lectures online, you will participate. You will do homework assignments, take exams, participate in discussions with other students, ask questions of the instructors, and also get a final score.

Basic and Advanced Tracks

This course is offered in two tracks. The advanced track is intended to be an undergraduate or early graduate level course, and you should plan on spending around ten hours a week or more on it. It will involve weekly homework assignments as well as a midterm exam and a final exam. In order to receive a statement of accomplishment for the advanced track you must take both the midterm and the final exam.

The basic track is for people interested in the material but who do not have time or would prefer not to do homework assignments and exams. You will be able to view the same lectures as the advanced track, and will have access to the homework assignments and exams after they have been completed by students in the advanced track but will not be scored on them. In order to receive a statement of accomplishment for the basic track you must stay active and continue to view material throughout the course.

You may switch between the tracks at any time, but be aware that while you are signed up for the basic track you will not have access to homework assignments or exams, and this will affect your score and eligibility if you decide to change back to the advanced track.

Basic and Advanced Tracks

We offer the machine learning class in two tracks. The advanced track is intended to be an undergraduate or early graduate level course, and you should plan on spending around ten hours a week or more on it. It will involve watching video lectures, weekly review questions and programming exercises.

The basic track is for people interested in the material but who do not have the time or would prefer not to do the programming assignments. You will be able to access the same materials as the advanced track, including the programming assignments, but you will not be scored on them. You may switch between the tracks at any time.

Pectoral fin muscle formation in paddlefish (Polyodon spathula) utilises the fully derived mode of appendicular muscle formation and is not associated with an epithelial extension. (Credit: Cole et al., PLoS Biology, DOI: 10.1371/journal.pbio.1001168)

ScienceDaily (Oct. 7, 2011) — A study into the muscle development of several different fish has given insights into the genetic leap that set the scene for the evolution of hind legs in terrestrial animals. This innovation gave rise to the tetrapods -- four-legged creatures, and our distant ancestors -- that made the first small steps on land some 400 million years ago.

A team of Australian scientists led by Professor Peter Currie, of the Australian Regenerative Medicine Institute at Monash University, and Dr Nicolas Cole, of the University of Sydney, report their results October 4 in online, open access journalPLoS Biology.

Scientists have long known that ancient lungfish species are the ancestors of the tetrapods. These fish could survive on land, breathing air and using their pelvic fins to propel themselves. Australia is home to three species of the few remaining lungfish -- two marine species and one inhabiting Queensland's Mary River basin.

There are big gaps in our knowledge, however. Most conclusions have previously been drawn from fossil skeletons, but the muscles critical to locomotion cannot be preserved in the fossil record. The team used fish living today to trace the evolution of pelvic fin muscles to find out how the load-bearing hind limbs of the tetrapods evolved. They compared embryos of the descendants of species representing key turning points in vertebrate evolution to see if there were differences in pelvic fin muscle formation. They studied "primitive" cartilaginous fish -- Australia's bamboo shark and its cousin, the elephant shark -- as well as three bony fishes -- the Australian lungfish, the zebrafish and the American paddlefish. The bony fish and in particular the lungfish are the closest living relative of the tetrapods' most recent common ancestor with fish.

"We examined the way the different fish species generated the muscles of their pelvic fins, which are the evolutionary forerunners of the hind limbs," said Professor Currie, a developmental biologist. Currie and his team genetically engineered the fish to trace the migration of precursor muscle cells in early developmental stages as the animal's body took shape. These cells in the engineered fish were made to emit a red or green light, allowing the team to track the development of specific muscle groups. They found that the bony fish had a different mechanism of pelvic fin muscle formation from that of the cartilaginous fish, a mechanism that was a stepping stone to the evolution of tetrapod physiology.

"Humans are just modified fish," said Professor Currie. "The genome of fish is not vastly different from our own. We have shown that the mechanism of pelvic muscle formation in bony fish is transitional between that in sharks and in our tetrapod ancestors."

Robert Young leaves court. 6 Oct 2011

Robert Young said he didn't want to believe that Jeffrey Jarrett was dead

One of two men accused of driving around a US city with their friend's corpse in the back seat thought the dead man was just drunk, a court heard.

Robert Young said he "wanted to believe" that Jeffrey Jarrett had simply passed out.

Mr Young and Mark Rubinson visited bars and a strip club and withdrew cash using Mr Jarrett's card before reporting his death, Denver police say.

They face charges including identity theft and abuse of a corpse.

Authorities are awaiting autopsy results to determine how and when 43-year-old Mr Jarrett died.

"In my mind, I wanted to believe he was passed out," Mr Young, 43, told the court hearing.

"I didn't want to call 911 (emergency number). I didn't want to believe he was dead."

Police say the night on the town started when Mr Young went to Mr Jarrett's home on 27 August and found him unresponsive.

Instead of calling for help, Mr Young went to find Mr Rubinson, 25, it is alleged.

The pair then put the body in Mr Rubinson's car and went to two bars in Denver where they spent some time drinking while the corpse was left in the car, police records say.

Police say the men used Mr Jarrett's bank card to pay for the drinks.

Mr Young said he then realised Mr Jarrett was dead and the two men took his body back to his home and left it on a bed.

They then went to Shotgun Willie's, a strip club in nearby Glendale, where they withdrew $400 (£253) from Jarrett's account from a cash machine, police said.

Later the men later flagged down a police car and told officers they thought their friend was dead and where his body was, according to the police statement.

Mr Jarrett was pronounced dead at his home in Denver on 28 August.

Neither men face charges in connection with Mr Jarrett's death.

Mr Young was due to enter a plea on Thursday but his lawyer was granted an extension until 3 November.

The latest stats coming out of France's HADOPI "three strikes" (really three accusations) policy are really quite stunning. Most of the focus is on the fact that 60 ISP account holders have received their third strike, and now await to see if they'll be fined and/or kicked off the internet without ever having actually been convicted of copyright infringement. But, to me, the much more interesting numbers are the first and second strike numbers. An astounding 650,000 people have received "first strike" notices, with 44,000 of those receiving a second strike as well. Those are huge numbers. It makes you wonder, at what point do those in power begin to recognize that if so many people are engaging in this, there must be some sort of better solution.

 

Well its a law it has to be upheld right? even for the MPAA?

BOOM!

No more MPAA! They're offline forever! After all, the law is just and equal and fair and blind, right? And the MPAA -- the people who, let's face it, basically *wrote* this law -- should be held to the highest standard themselves. They, more than anyone else, cannot call it a youthful mistake, or a silly error in judgement, or ignorance or anything else... they have zero excuse and so accordingly they will be punished for their obvious and flagrant transgressions!

Right? ... right? guess not

IFO1 Chinese Farmer Builds and Flies Identified Flying Object  picture

UFOs are one thing, but identified flying objects, (IFOS) while not as mysterious and spine-tingling, are something else entirely.

In this case, effects are just as amazing, considering that the creator of this IFO is a farmer who built his Octocopter in his spare time, equipped with the barest of an education and no training of any kind either in mechanics or engineering.

Shu Mansheng, aged 46, has always been fascinated by aviation. In the past, he built two jet planes in his home, but both projects failed.

Shu has recently successfully completed a test flight in the 18-foot diameter flying saucer powered by eight motor-bike engines, which cost him £3,000 (about $US 5,000) to develop.

Shu is not a man who gives up easily, as this effort marked his second attempt to get his flying saucer off the ground.

Last month he managed to take off in the Octocopter but only for a few seconds.

This time, however, he reached a controlled height of six feet for more than 30 seconds.

IFO2 Chinese Farmer Builds and Flies Identified Flying Object  picture

Shu’s work is far from finished as he plans to further refine his Octocopter.

He has another even nobler noble mission as well, which touches upon what he has missed in his own life.

“My dream is to establish a special school where kids would be able to learn all sorts of things they don’t teach in ordinary schools,” Shu told the press

Of all the people in the world, Shu Mansheng is one of the few who probably understands how Orville and Wilbur Wright must have felt that momentous day back in 1903 at Kitty Hawk, North Carolina.

Go Shu, go!

Nobel laureates Perlmutter, Schmidt, and Riess

The three researchers' work has led to an expanding knowledge of our Universe

 

Three researchers behind the discovery that our Universe's expansion is accelerating have been awarded this year's Nobel prize for physics.

Saul Perlmutter and Adam Riess of the US and Brian Schmidt of Australia will divide the prize.

The trio studied what are called Type 1a supernovae, determining that more distant objects seem to move faster.

Their observations suggest that not only is the Universe expanding, its expansion is relentlessly speeding up.

Prof Perlmutter of the University of California, Berkeley, has been awarded half the 10m Swedish krona (£940,000) prize, with Prof Schmidt of the Australian National University and Prof Riess of Johns Hopkins University's Space Telescope Science Institute sharing the other half.

'Weak knees'

Prof Schmidt spoke to the Nobel commitee from Australia during the ceremony.

"It feels like when my children were born," he said.

"I feel weak at the knees, very excited and somewhat amazed by the situation. It's been a pretty exciting last half hour."

The trio's findings form the basis of our current understanding of the Universe's origins, but raises a number of difficult questions.

In order to explain the rising expansion, cosmologists have suggested the existence of what is known as dark energy. Although its properties and nature remain mysterious, the predominant theory holds that dark energy makes up some three-quarters of the Universe.

But at the time the work was first being considered, no such exotic explanations were yet needed.

"It seemed like my favourite kind of job - a wonderful chance to ask something absolutely fundamental: the fate of the Universe and whether the Universe was infinite or not," Prof Perlmutter told BBC News.

Dark energy and dark matter mysteries

Dark matter distribution simulation

 

He led the Supernova Cosmology Project beginning in 1988, and Prof Schmidt and Prof Riess began work in 1994 on a similar project known as the High-z Supernova Search Team.

Their goal was to measure distant Type 1a supernovae - the brilliant ends of a particular kind of dense star known as a white dwarf.

Because their explosive ends are of roughly the same brightness, the amount of light observed from the supernovae on Earth should be an indication of their distance; slight shifts in their colour indicate how fast they are moving.

At the time, the competing teams expected to find that the more distant supernovae were slowing down, relative to those nearer - a decline of the expansion of the Universe that began with the Big Bang.

Instead, both teams found the same thing: distant supernovae were in fact speeding up, suggesting that the Universe is destined for an ever-increasing expansion.

Prof Perlmutter said the fact that the two teams were rivals was probably best to set the scene for a surprising outcome.

"It was fierce competition in those last four or five years of the work," he said.

"The two groups announced their results within just weeks of each other and they agreed so closely; that's one of the things that made it possible for the scientific community to accept the result so quickly."

That result in the end sparked a new epoch in cosmology, seeking to understand what is driving the expansion, and Prof Perlmutter is enthusiastic that such fundamental problems have been highlighted by the Nobel committee.

"It's an unusual opportunity, a chance for so many people to share in the excitement and the fun of the fact that we may be on to hints as to what the Universe is made out of. I guess the whole point of a prize like this is to be able to get that out into the community."

Commenting on the prize, Prof Sir Peter Knight, head of the UK's Institute of Physics, said: "The recipients of today's award are at the frontier of modern astrophysics and have triggered an enormous amount of research on dark energy."

"These researchers have opened our eyes to the true nature of our Universe," he added. "They are very well-deserved recipients."

The Nobel prizes have been given out annually since 1901, covering the fields of medicine, physics, chemistry, literature and peace.

Monday's award of the 2011 prize for physiology or medicine went to Bruce Beutler of the US, Jules Hoffmann from France and Ralph Steinman from Canada for their work on immunology.

This year's chemistry prize will be announced on Wednesday.

Wiola Nowicka, 67, attempted to turn around in the car park's narrow driveway once she noticed the high prices she would have to pay.

Nowicka's bad sense of judgement resulted in the driveway being blocked for five hours, as her car was wedged between the driveway walls.

'I didn't mean to be a nuisance,' said Nowicka. 'After a few turns I couldn't go backwards or forwards any more.'

Engineers were able to get the car out from the tight space, with careful inch by inch precision.

Nowicka isn't the only driver over 50, to have misjudged at the wheel.

Earlier this year, an 86-year-old Californian woman crashed her car through the Rock N' Road cycling shop, narrowly missing customers.

Authorities discovered that the woman had hit the accelerator pedal by mistake, instead of the break.

Lucky no one was hurt in either of the incidents.

Dendritic cell

Ralph Steinman was awarded for his discovery of the dendritic cell

 

Three scientists who "revolutionised" understanding of how the body fights infection have shared this year's Nobel prize for medicine.

Bruce Beutler, of the US, Jules Hoffmann from France and Ralph Steinman from Canada all shared the prize.

Profs Beutler and Hoffman discovered how the body's first line of defence was activated.

Prof Steinman discovered the dendritic cell, which helps defeat infection.

Twin defences

The immune system can be broadly divided into two parts: innate and adaptive.

The innate immune system is the immediate response and halts infection by destroying foreign microorganisms and triggering inflammation.

In 1996, Prof Hoffmann discovered that a gene called "Toll" was essential for kick starting the innate system in fruit flies. Without the gene, the flies could not "sense" and then fight bacterial infection.

An equivalent gene, Toll-like receptor, was found by Prof Beutler in 1998 in his study on mice.

More than a dozen Toll-like receptors have since been found in humans.

The adaptive immune system takes longer to activate, but clears the infection and can provide long lasting protection.

Prof Steinman discovered, in 1973, the dendritic cell. He showed that it can act as a bridge between the two immune systems, deciding whether to activate the adaptive system.

The Nobel prize committe said: "Together Bruce Beutler, Jules Hoffmann and Ralph Steinman have revoluntionised understanding of the immune system by discovering key principles for its activation.

"They have opened up new avenues for prevention and therapy."

Professor of clinical allergy research and panel member, Annika Scheynius, said: "We are definitely sure that these discoveries will lead to health improvement, mainly in the terms of new vaccines.

"Different types of vaccines that are targetting the dentritic cells, meaning that we can improve the health of patients with cancer, inflammatory diseases, auto-immune diseases, asthma."

Spider's victim ... the body of tragic Voegel is taken away

Police broke in to Mark Voegel’s apartment to find spider Bettina along with 200 others, several snakes, a gecko lizard called Helmut and several thousand termites had gorged on his body.

Neighbours alerted police after becoming alarmed by the stink.

And horrified officers were met by a nightmare scene.

 

Spider's victim ... the body of tragic Voegel is taken away

A police spokesman said: “It was like a horror movie. His corpse was over the sofa.

“Giant webs draped him, spiders were all over him. They were coming out of his nose and his mouth.

“There was everything there one could imagine in the world of reptiles.

“Larger pieces of flesh torn off by the lizards were scooped up and taken back to the webs of tarantulas and other bird-eating spiders.”

Hungry ... termites ate body

Hungry ... termites ate body

Loner Voegel, 30, never invited people back to his “jungle” home, a small apartment in the German city of Dortmund.
Police described it as a cross between a botanical garden and the butterfly breeding ground in the serial killer movie The Silence Of The Lambs.

One tarantula had built a nest the size of a swallow’s in a corner of the ceiling.

Voegel also had a boa constrictor and several poisonous frogs from South America.

Spider expert and animal cruelty officer Gabi Bayer said he kept creatures “that should never be allowed in a private home”.

She said: “He had spiders so aggressive they are the equivalent of a pit-bull in the animal world.”

The reptiles were allowed to roam free in the flat.

The heating elements on two tanks containing spiders and their termite snacks had exploded and dislodged the metal tops allowing them to escape.

Voegel is thought to have been dead for between seven and 14 days.

A post-mortem will be carried out in the next few days. But authorities believe Bettina alone was responsible for Voegel’s death.

The challenge of Hawaii’s grueling Ironman Triathion course is a formidable goal for anyone, but for a tiny Japanese robot known as Evolta, it would seem to be an impossible task.

green evolta Toy Robot Prepares For Ironman Triathlon picture

But Evolta is no stranger to hardship as this Panasonic creation has already scaled the cliffs of the Grand Canyon, endured the Le Mans 24-hour circuit racetrack and has walked 310 miles from Tokyo to the old Japanese capital of Kyoto.

The hand-sized, green and white robot gets its stamina from three rechargeable batteries, which the robot bears on its back, and is fitted with three different bodies to accommodate the different physical challenges. These include: one mounted on a tiny bicycle, one in a round hoop with a supporting rear wheel and another mounted on a curved, fin-like blade.

Evolta will swim, bicycle and run its way through one of the world’s toughest triathlon routes, which commences on October 24 and will continue without stopping for seven days and nights.

“This is very tough even for a sportsman, but I think it is worth a challenge… Evolta’s height is just one-tenth of a grown man, so we figured out that it would take it 10 times more time. … I hope it will … succeed in the end,” said Tomotaka Takahashi, creator of Evolta.

The robot’s assignment is to swim, run and bike for approximately 143 miles. The time given to complete the task is one week or 168 hours, which is ten times longer than it would take a human of normal proportions.

Evolta’s creator had his own challenges as well. For one thing, he had to find away to make the tiny robot impervious to moisture and effectively protect it from mold. The batteries are slated to go on sale in late October. They have a long life and can be recharged up to 1,800 times via a recharger pad.
