One of Mexico’s most successful cartoonists, Gabriel Vargas, died yesterday at the age of 95. His death was announced by the National Council of the Arts and Culture. Vargas had been ill for several years before his death, but no cause of death has yet been given.

Vargas’s most successful comic strip was “La Familia Burron” which he started in 1937. The strip looked at a low-income family struggling with everyday life. It sold up to 500,000 copies per week until the 1970s.

Later in his career he won several awards for his work, including Mexico’s National Journalism Prize in 1983 and the National Sciences and Arts prize in 2003.

There was a memorial viewing for Vargas at a funeral home in Mexico City yesterday.

2007 the 33rd Taipei International Electronics Autumn Show (TAITRONICS Autumn), organized by Taiwan External Trade Development Council (TAITRA) and Taiwan Electrical and Electronic Manufactorers’ Association (TEEMA), started on October 9 -13 at Exhibition Hall 1 and 3 of Taipei World Trade Center (TWTC), and inconjunction with Taiwan International RFID Applications Show (RFID Taiwan) at TWTC Hall 3 and Taiwan International Photovoltaic Fourm & Exhibition (PV Taiwan) at Taipei International Convention Center (TICC). With the 3-in-1 combination, TAITRA and TEEMA hoped this show will integrate upper and lower companies of electronic manufacturers and companies in Taiwan.

This 3-in-1 show is mainly focused on electronics parts and components, RFID solutions, photovoltaic products, and medias on electrical industry. About 1000 exhibitors exhibited with 2100 booths at TWTC Hall 1 & 3 and TICC. In the theme pavilion section, iF Design Award in Hanover Fairs set “iF Design Pavilion” with lots of awarded 3C products in Taiwan first time, also, Industrial Technology Research Institute (ITRI) showed their solutions on home entertainment such as 3D LCD wide screen display and game projector.

Not only ITRI and iF Design, TAITRA and TEEMA also set “Taiwan Innovalue and Branding Taiwan”, “Product Certificates and Testing”, “Cross-Strait Electrical Products”, “Security Products”, and “Broadband Communications” pavilions at this exhibition.

With those pavilions, TEEMA also held lots of seminars and forums on Bluetooth technology, electrical industry, testings and certifications, and International Electrotechnical Commission Quality (IECQ) system. Furthermore, CARTS Asia 2007 is the most welcomed seminar by buyers and exhibitors.

According to TAITRA, this 3-in-1 exhibition opened daily from 9 a.m. to 5 p.m. at October 9 to 13, PV Taiwan forum and exhibition will be held only two days on October 11 and 12. For the quality and security issue, minors under 18 ages are not permitted to enter the showground.

At least fifteen people have been killed as the result of a landslide which occurred in Indonesia on Tuesday. According to BBC News Online, at least sixteen were killed. It is thought that up to seventy people were killed as a result of the landslide, which occurred in a village near to the city of Bandung.

At one point, villagers attempted to dig out surviving victims from the rocks and mud by using their bare hands, as rescue efforts were suspended temporarily due to heavy rain, before recommencing after lifting equipment arrived. At least sixteen dead bodies have been recovered by Wednesday. Roughly five hundred people are contributing to the search and rescue.

Priyadi Kardono, spokesperson for the Disaster Management Agency, stated: “We’ve found fifteen bodies so far and estimate that there are up to 70 people still missing.” He also commented that fifteen other people had been injured, of which two have been hospitalised.

At least two people have died and at least eight to ten were injured after two semi trucks collided in a truck tunnel on Interstate 5 (Newhall Pass) between Los Angeles and Santa Clarita California, United States, causing the tunnel to be completely shut down on both north and southbound lanes.

At approximately 11:00 p.m. (pacific time), two semi trucks collided and at least 13 other trucks smashed into the wreckage causing a massive fire. Firefighters are using foam to control the flames, which could take several hours to put out.

Officials say that the debris could take a day or more to remove and that a full inspection will have to be done on the tunnel before it can be used again because officials say that the structure of the tunnel has been compromised.

“It has impacted the structural stability of the tunnel,” said John Tripp the Fire Chief for Los Angeles County who also said that there may be more people trapped in the wreckage.

“We’re going to have to do a very methodical search. There could be unfortunately more people that were not able to escape,” added Tripp.

The tunnel is 200 feet long.

A Russian mathematician, Grigori (“Grisha”) Perelman, who is credited proving the Poincaré conjecture declined to accept the Fields Medal, regarded as the highest honor in the field of mathematics.

The Fields Medal, often referred to as the “Nobel Prize of mathematics”, was awarded this year to Andrei Okounkov (Russia/US), Terence Tao (Australia/US) and Wendelin Werner (France) in addition to Perelman. The award was handed out by King Juan Carlos of Spain and is accompanied by a C$15’000 (approximately US$13’400 or 10’400EUR) cash prize (less than the one million Euros that come with the Nobel prize). Nominees have to be under 40 years, because the founder of the award, Canadian mathematician John Charles Fields wanted the medal to be a stimulus for future endeavours.

Perelman submitted two papers in 2002 and 2003 outlining a proof for Thurston’s geometrization conjecture, which in turn, implies a proof for the Poincaré conjecture. Other mathematicians filling in the details have found no flaws in Perelman’s approach yet. In 2003, Perelman made a short tour in the United States to explain his proof of the conjecture. When he went back to the St Petersburg department of the Steklov Institute of Mathematics, he gave up his job, and is reported to be unemployed and living with his mother ever since.

“The reason Perelman gave me is that he feels isolated from the mathematical community and therefore has no wish to appear as one of its leaders.” declared Manuel de Leon, chairman of the Congress, when asked about Grisha’s motivation to decline. Prof. John Ball, retiring president of the International Mathematical Union, added: “The reason centres on his feeling of isolation from the mathematical community.” Perelman’s friend Anatoly Vershik said the reclusive math genius just wanted to be declared correct, and regarded recognition as superficial.

The Poincaré conjecture is widely considered one of the most important questions in topology (a branch of mathematics concerned with spatial properties preserved under deformation like stretching without tearing or gluing). It is one of the seven Millennium Prize Problems for which the Clay Mathematics Institute is offering a $1,000,000 prize for a correct solution.

Observers speculate that he will also refuse this prize. In 1997, he also refused an award by the European Congress of Mathematicians, because he deemed the judges unable to understand his work. A spokesman for the Institute said it would decide on the prize in two years. Richard Hamilton’s “Ricci flow” equation could also earn him a part of the prize, since it formed the basis for Perelman’s papers.

In 1966, German Alexander Grothendieck refused his Fields Medal in Moscow out of protest against the presence of the Red Army in Eastern Europe. But later he accepted it.

The Poincaré conjecture is not an easy thing to explain in plain English. A sphere as we know it is called a two-dimensional sphere in topology (because it’s surface can be approximated by a two-dimensional plane). The four-dimensional analogue of such a 2-sphere is a 3-sphere (which is an example of a 3-manifold).

Now imagine a ball and a donut made of rubber. If you throw a lasso around the ball and pull, you can squeeze it to a single point and slide off the lasso. But you can’t do that with the noose through the hole of a donut, the only way is to cut through the donut. So in topology, there are basically two kinds of objects: objects with or without holes. By deforming objects without holes you can make them look like a sphere, but this is impossible for objects with holes. So basically, Grisha proved that in topology a ball and a banana are the same.

The Poincaré conjecture surmises that if a closed three-dimensional manifold (our multiple-dimension banana) is sufficiently like a 3-sphere (a kind of hypersphere) in that each loop in the manifold can be tightened to a point, then it is really just a three-dimensional sphere.

In February 2017, the Iranian Chess Federation announced two teenage chess players, Dorsa Derakhshani and her younger brother Borna Derakhshani, were banned from representing the national team. The federation announced their decision although Dorsa Derakhshani had previously decided and informed the chess federation she did not wish to play for Iran.

Dorsa Derakhshani is currently 21 years old and holds the International Master (IM) as well as Woman Grand Master (WGM) titles. Her brother, Borna, plays for the English Federation and holds the FIDE Master title.

Dorsa Derakhshani was banned since she did not wear a hijab, an Islamic headscarf, while competing at the Tradewise Gibraltar Chess Festival in January 2017. Under the laws of Islamic Republic of Iran, hijab is a mandatory dress code. Her brother Borna Deraskhsani was banned for playing against Israeli Grand Master (GM) Alexander Huzman at the same tournament. Iran does not recognise the existence of Israel, and previously, Irani athletes have avoided playing against Israeli athletes.

Mehrdad Pahlavanzadeh, the president of the country’s chess federation, explained the decision to ban the players saying, “As a first step, these two will be denied entry to all tournaments taking place in Iran and in the name of Iran, they will no longer be allowed the opportunity to be present on the national team.” ^{((fa))Farsi language: ?????? ????? ?? ??? ??? ?? ??? ????? ?? ?? ???? ???????? ?? ?? ????? ? ?? ??? ????? ?????? ??????? ????? ??????? ? ???? ???? ???? ?? ??? ??? ?? ??????? ????.} He further stated, “Unfortunately, something that should not have happened has happened and our national interest is paramount and we have reported this position to the Ministry of Sports.” ^{((fa))Farsi language: ????????? ?????? ?? ????? ????????? ?????? ??? ? ????? ??? ?? ?? ?? ???? ?????? ???? ? ?? ??? ???? ?? ?? ????? ???? ?? ????? ?????.}

IM Dorsa Derakhshani, who currently studies at Saint Louis University in the United States and plays for the United States Chess Federation, discussed her chess career, time in Iran and the 2017 controversy, and her life in Saint Louis with a Wikinews correspondent.

Chemotherapy is usually associated with a collection of side effects ranging from digestive problems to hair loss, but a study published this week in Human Reproduction demonstrated that female cancer patients may find they have something in common with much younger women in one specific area — their ovaries.

Scientists from the University of Edinburgh examined donated ovarian tissue from fourteen female cancer patients, most of whom had Hodgkin lymphoma, and compared it to tissue from healthy women. They found the samples from women who had been treated with a specific chemotherapeutic regimen known as ABVD not only contained greater numbers of dormant ova — egg cells — than those from women treated with harsher regimens but also more than samples from healthy women. ABVD is named for combining several drugs known as adriamycin, bleomycin, vinblastine, and dacarbazine.

These reproductive cells were not merely more plentiful in ABVD patients. They also appeared immature, “new” in the words of lead researcher Evelyn Telfer. This challenges the conventional belief that girls are born with all the ova they will ever have and the numbers can only go down as the cells are either used up by the reproductive cycle or succumb to damage or natural aging. However, further research is needed to confirm this. The study covered relatively few patients by scientific standards, and David Albertini of the Center for Human Reproduction in New York has suggested the cells may not actually be freshly grown. Instead, they may have always been there and were merely rendered more detectable by ABVD treatment.

The ability to grow new egg cells may have significant implications for women in Western societies, many of whom postpone childbearing to establish careers, sometimes into their late thirties or forties. However, Telfer warns against making use of these findings too soon: “There’s so much we don’t know about the ovary. We have to be very cautious about jumping to clinical applications.”

The experiments had been discussed earlier this year at the annual conference of the European Society of Human Reproduction and Embryology.

A trio of Canadian trekkers said Friday they completed the fastest unaided on-foot trek using the traditional route from Hercules Inlet on the Ronne Ice Shelf to the South Pole in a record time of 33 days, 23 hours and 30 minutes. Ottawa ultra-runner Ray Zahab, age 39, adventure journalist and architect Kevin Vallely, age 44, of Lynn Valley, North Vancouver and North Pole expeditionist Richard Weber, age 49, said they completed the 700-mile (1,130-kilometer) journey, at 10,000 feet altitude, finally arriving early Wednesday morning.

They endured a white-out but survived on a 7,000-calorie-a-day diet of pemmican, Gatorade drink powder, outdated salami, deep-fried bacon, cheese and butter. “If you took a cloud, wrapped it around your head and then duct-taped it, that’s what a white-out is like,” Mr Zahab, explained. The trio also suffered altitude sickness, vertigo, massive, painful blisters, and temperatures as low as minus 40. Zahab had to pull 170-lb (77-kg) sleds of equipment, traveling on foot and on snowshoes while the other two men skied.

According to ExplorersWeb.com’s founder, Tom Sjogren, the trio erased the previous record of 39 days, 7 hours and 49 minutes, which was set by American Todd Carmichael, the first American to cross Antarctica to the South Pole alone, on foot and with no assistance. He arrived at The Pole on December 21, 2008. “They have definitely broken the record,” said Sjogren. Guinness World Records spokesman, Damian Field, in London, however, said that “Guinness monitors a category for fastest unsupported trek to the South Pole, but it has no record currently listed.”

Prior to Carmichael, the record was held by Briton Hannah McKeand. In the fastest journey to the South Pole (600 nautical mile journey), she completed solo and in just 39 days, 9 hours and 33 minutes. In March 2008 she attempted to reach the North Pole alone and unsupported but had to abandon the trip after falling through the ice and badly damaging her shoulder.

Ray Zahab is a Canadian ultramarathon runner, personal trainer, and motivational speaker. He lives in Chelsea, Quebec, and is famous for his 4,300-mile (6,920-kilometer) epic run across the Sahara Desert in 2007, which was the subject of a documentary narrated by actor Matt Damon‘s “Running the Sahara.” He heads Impossible2Possible, a nonprofit organization which advocates planet protection. “I started looking at impossible places on the planet in the past year, and I said Antarctica is one of those impossible places, and if we can create an expedition, perhaps we can inspire a bunch of young people to realize they can achieve,’ Zahab said.

Richard Weber, M.S.M. (born June 9, 1959 in Edmonton, Alberta) is a world-renowned Canadian Arctic and polar adventurer, from Alcove (near Wakefield). From 1978 to 2006, he participated in, lead and organized more than 45 Arctic expeditions. Richard is the only person to have completed six full North Pole expeditions. He has therefore trekked to the North Pole more than anyone in history.

The trio were waiting out a storm before boarding a flight to Chile for Ottawa. “I’m pretty tired, actually,” said Kevin Vallely, calling from Patriot Hills, Antarctica. During the saga, Vallely was solely burdened with carrying the high-tech gear in his sled consisting of video cameras, satellite phones, hand-held computers, different kinds of solar panels, batteries and wires chargers. “Had we not brought all that stuff we probably would have got it done faster because we wouldn’t have had to carry all that weight, but then it doesn’t matter as much,” he explained. Vallely said he also intends to produce a documentary of the expedition.
