The U.K. government defined Intelligent Design along with creationism as religion and ruled that neither has a place within the country’s school science curriculum.

This was in reaction to an electronic petition launched by James Rocks of the “Science, Just Science” campaign, a group formed to oppose “Truth in Science” and other groups in the anti-evolution lobby in the UK. The petition was signed by 1,505 people.

In the petition details, Rocks wrote, “Creationism & Intelligent design are greatly featured in the media and are being used disingenuously to portray science & the theory of evolution as being in crisis when they are not. Moreover groups such as Truth in Science are targeting our nation’s children and their science education with material that is not only non-scientific but have been rejected by the scientific community. These ideas therefore do not constitute science, cannot be considered scientific education and therefore do not belong in the nation’s science classrooms.”

A spokesperson for the Prime Minister’s office wrote: “The (UK) Government is aware that a number of concerns have been raised in the media and elsewhere as to whether creationism and intelligent design have a place in science lessons. The [UK] Government is clear that creationism and intelligent design are not part of the science National Curriculum programmes of study and should not be taught as science.”

The government will also be “publishing guidance for schools, on the way creationism and intelligent design relate to science teaching”.

Reports from Amnesty International and an attorney representing some detainees indicate that hunger strikes continue among those held at the United States detention facility in Guantanamo Bay, Cuba. More than 200 prisoners are participating in the hunger strike — of these, 21 are being force fed by military personnel.

According to human rights lawyer Clive Stafford Smith, the prisoners have been shackled to their beds to prevent them removing the feeding tubes that have been inserted into their noses. “The notion that a qualified medical practitioner would be prepared to supervise such a procedure (as force-feeding through a tube), goes against all medical ethics, certainly in this country,” said Trevor Turner, a director of St. Bartholomew’s Hospital of London.

Military authorities maintain that only 36 detainees are currently strikers — they define a hunger striker as one who has refused at least nine meals. According to U.S. military personnel, a striker is only force-fed when his life is in danger.

Some detainees have been striking since August to protest the alleged inhumane conditions at the camp as well as their indefinite confinement without charge or normal legal rights, according to attorneys representing them.

At least nine people have died in northern Italy after a landslide caused the derailment of a passenger train. A further 25 people were injured, according to emergency services.

The incident occurred earlier this morning near the border with Austria, in a mountainous region near Merano, a city around 300 kilometres north of Venice.

“There are nine confirmed victims, while 28 people have been injured, seven of them seriously,” reported the governor of the Bolzano-Bozen province, Luis Durnwalder, to the Reuters news service. Initially, eleven people were reported dead, due to what the governor described as a “counting error”. However, he noted that “there could still be someone buried in the mud”, so the death count is not yet final.

According to the ANSA news agency, the train had about forty passengers on board when it derailed. Sky TV, meanwhile, quoted officials as saying that three people are reported to be missing. The authorities say the landslide was due to a broken irrigation pipe, which caused rocks to fall onto the tracks below. Authorities say they are looking into why the pipe burst.

The trains front car hit two trees upon derailment, local media says, which prevented it from dropping off into a river below. The carriage, however, was hanging over the river, and firefighters had to use cables to stop it from falling any more. A crane was also dispatched the scene to help clean up debris, ANSA reported.

“The train is hanging off the rails about five meters from the river. It is now only a few trees that are holding up the train and preventing it falling into the river,” said a witness, Alex Rowbotham, to the BBC.

“[…] The landslide occurred at the very passage of the train. It hit the train,” said Thomas Widmann, a transport official for the city of Bolanzo.

The crash was the deadliest in Europe since February, when eighteen people died after two commuter trains ran into each other near Brussels, Belgium. Italy saw its worse rail crash two decades ago, when 29 people died following the derailment of a freight train carrying petroleum gas, resulting in several explosions.

A University of Tokyo group of researchers, led by bioengineer Shoji Takeuchi, has made an electronic sensor capable of smelling gases. The sensor uses genetically engineered frog cells. Since previous sensors were not very accurate, the scientist decided to try a biological approach. The invention was revealed in a US scientific journal yesterday, and is supposed to be used to design better machines to detect polluting gases in the atmosphere.

Previous smell sensors were based on quartz rods, which vibrate when a substance binds to them. The gases are distinguished by their molar masses, which can be similar for molecules with different structure, thus relatively often triggering a false positive. Trying to find a more accurate solution, Takeuchi decided to follow an example from insect world. As he explained, “when you think about the mosquito, it is able to find people because of carbon dioxide from the human. So the mosquito has CO₂ receptors. When we can (extract) DNA (from the mosquito) we can put this DNA into the frog eggs to detect CO₂.”

Genes of several insects (the silk moth, diamondback moth and fruit fly), injected into African clawed frog Xenopus laevis eggs, allowed them to produce relatively inexpensive and useful sensors. The choice of the species was caused by their widely studied and well-understood protein expression mechanism.

The modified cells responded to three kinds of pheromones and one odourant, which have similar chemical properties. When a molecule of an odorous substance adhered to the receptor on the membrane protein, ion channels opened for a certain period of time, and a current was generated. Its magnitude was clearly different for all four tested substances, allowing to distinguish between them accurately.

The colleagues embedded the sensor into a mannequin, so that it could shake its head when a gas was detected. It was easier to observe. Pheromones and molecules with quite similar molecule structure produced clearly distinguishable reaction, with higher accuracy than other biological or human-made sensors. As the research group said, the detection sensitivity of the odor sensor is several tens of parts per billion (ppb), and it is as high as the sensitivity of an existing odor sensor that uses an oxide semiconductor. The distinctive feature of the new sensor is its capability to selectively detect some odorous substances, rather than its sensitivity. Very few false positives were possible due to the biological mechanism involved.

At normal temperature, the sensor lifetime is about 12 hours, which can be extended by putting it into a refrigerator before first use.

Shoji Takeuchi says has a great hope for research use in future, since the frog eggs are very practical for genetic engineering, and can be conveniently used to develop smell sensors for a wide range of gases. He said, “The X. laevis oocyte has high versatility for the development of chemical sensors for various odorants. We believe that a shared ability to smell might open a new relationship between man and robot. .. The research will have wide implications… If the sensor is embedded in a nursing robot, it will be able to identify certain mouth odors or body odors. Also, it can be used for detecting CO₂, air pollution, water pollution and food. It’s very important for the environment.”

Investigators examining the wreck of British Airways Flight 38, a Boeing 777 that crash landed short of the runway at London’s Heathrow Airport in the first hull loss of a 777, are examining the aircraft’s fuel system as a possible factor in the crash. No-one was killed as the scheduled flight from Beijing, China lost power during final approach on January 17.

136 passengers and 16 crew were on board when power was lost to the two Rolls-Royce engines about two miles from the runway, at a height of 600 feet. Autopilot and autothrottle were engaged at the time, the latter having just commanded an increase of thrust to the engines when power was lost. Co-pilot John Coward, in control at the time, was subsequently praised for being able to glide the disabled plane to within 1,000 feet of the runway, clearing a number of houses along the way.

Subsequent investigation has revealed that not only did the engines not fail simultaneously, but neither failed completely, contradicting initial belief. A preliminary report by the United Kingdom’s Aircraft Accident Investigation Branch (AAIB) stated that after the autothrottle commanded more thrust “The engines both initially responded but after about 3 seconds the thrust of the right engine reduced. Some eight seconds later the thrust reduced on the left engine to a similar level… Both engines continued to produce thrust at an engine speed above flight idle, but less than the commanded thrust.” This situation prevailed until impact.

On Wednesday the AAIB stated that they were examining “All possible scenarios that could explain the thrust reduction and continued lack of response of the engines.” However, it also went on to specifically mention attention to the jet’s fuel system, saying “This work includes a detailed analysis and examination of the complete fuel-flow path from the aircraft tanks to the engine-fuel nozzles.” The AAIB also ruled out the plane having completely run out of fuel, stating that there was “adequate fuel” in the tanks when the plane crashed. In addition to the fuel required to get to the target destination or emergency alternative airport – whichever is further – aircraft typically carry between thirty and forty-five minutes worth of extra fuel as a safety margin.

Possible scenarios being examined include fuel contamination, coming either from fuel taken on at Beijing or leakage from an unknown source. In particular, a heavy contaminant at the bottom of the tanks would explain a lack of earlier problems on the flight, as the fuel levels would only have become low in the final stages of the trip. Another possibility is that a central part of the fuel system developed a leak, reducing the amount of fuel available to the engines.

It is known that, according to the AAIB, “the autothrottle and engine-control commands were performing as expected prior to, and after, the reduction in thrust,” suggesting that all software in the aircraft was functioning correctly and rendering a software failure unlikely, although this possibility also remains under investigation.

On Friday, Catalonian football club FC Barcelona announced Brazilian forward Neymar signed a five-year contract extension, which runs through June 2021.

Barcelona announced Neymar would be signing a contract extension in July, but Neymar was not physically present at their offices to sign at the time.

Neymar joined the Blaugrana in summer 2013 from Santos FC and since then has featured in 151 games for the Catalonian club. Neymar has won nine trophies with Barça — two La Liga titles, two Copa del Reys and Supercopa de España, and one each of UEFA Champions League, UEFA Super Cup, and FIFA Club World Cup scoring over 90 goals.

Per the contract extension, Neymar’s buyout clause is €200 million at the end of the current season which would rise to €250million by the third season.

After signing the contract extension, Neymar said, “I feel at home […] I am very happy with colleagues on the field” ^{((ca)) Catalonia language: Em sento a casa […] Em sento molt feliç a dins del camp amb els companys} .
