Just a day after the president of Argentina revealed that she is battling cancer, Venezuaelan president Hugo Chavez suggested in a televised speech that the United States may be plotting to infect Sout American leaders with cancer.

In a speech to troops on Wednesday, Chavez said:

"It would not be strange if they had developed the technology to induce cancer and nobody knew about it until now. It is very hard to explain, even with the law of probabilities, what has been happening to leaders in Latin America."

Chavez underwent surgery in June to remove a tumor from his pelvis. Argentine president Cristina Fernandez revealed this week that she has thyroid cancer, which she has been battling for a year. She will undergo surgery on January 4. Former Brazilian president Luiz Inacio Lula da Silva was diagnosed with throat cancer in October, and his successor, Dilma Rousseff, survived a battle with lymphoma in 2009. In August 2010, Paraguay president Fernando Lugo was diagnosed with non-Hodgkin lymphoma in August 2010.

Chavez insisted in his speech that he "wasn't accusing anyone", but noted that ex-Cuban dictator Fidel Castro had warned him of the U.S.'s biological cunning, saying:

The so-called "alien skull" recently discovered in Peru might not be so alien afterall. The skeletal structure features an oversized, triangular-shaped skull nearly as large as the being's small body, which have led many to conclude that it is not human and must therefore be an alien being from another planet. But even the man who discovered the remains insists that it is a human child with some type of deformity and not extraterrestrial life.

Peruvian anthropologist Renato Davila Riquelme made the discovery, and has declared the remains as those of a child. But the alien skull story picked up momentum when RPP, a Peruvian news site, published an article that featured a number of quotes from anonymous, unnamed Spanish and Russian scientists who claim that the remains are "clearly" those of an alien.

A statement from the scientists read:

"It has a non-human appearance. The head is triangular and big, almost the same size as the boy... yes, it's an extraterrestrial being."

On Friday, a magnitude 6.9 earthquake struck off the coast of southern Peru, injuring 83 people near the city of Ica.

Civil defense officials said on Saturday that at least 88 homes were destroyed, and an additional 40 homes were declared uninhabitable. No deaths have been reported.

According to the U.S. Geological Survey, the earthquake was centered under the ocean, 31 miles southwest of Ica. This is near the same place where a destructive magnitude 8.0 quake killed more than 500 people in 2007.

Injuries resulting from Friday's quake were relativel mild. The injured were mostly treated for bruises and fractures.

The quake was felt as far away as the capital of Lima, located 185 miles north of Ica. It caused no damage there, and the day went about as usual. No tsunami warnings were issued as a result of this quake, and officials said that large mines in the region were not damaged.

Over the weekend, Brazil elected its first-ever female president. In her victory speech, Dilma Rousseff said she wanted "fathers and mothers to look their daughters in the eyes and say, 'Yes, a woman can.'"

In electing Rousseff, Brazillians voted strongly in favor of continuing the economic and social policies of the popular Luiz Inácio Lula da Silva. Rousseff served as da Silva's chief of staff and energy minister.

Rousseff, 62, defeated José Serra, the former governor of São Paulo, with 56 percent of the vote to 44 percent. She now joins a growing wave of democratically elected female leaders in the South American region and the world in the past five years, including Michelle Bachelet in Chile, Cristina Fernández de Kirchner in Argentina and Angela Merkel in Germany.

Rousseff had no political experience and had never run for office. In electing her, voters sent a message that they preferred continue the economic policies of da Silva, whose administration deepened economic stability and lifted millions of Brazillians out of poverty and into the lower middle class.

Yonni Barrios was amongst the 33 men trapped in a collapsed mine for 69 days in Chile, but that's not why he made international headlines. Barrios garnered extra attention when it was revealed that he had both a wife and a mistress waiting for him above ground, and requested them both to be there upon his ascent from the mine.

Barrios' wife of 28-years refused to meet him, having learned of the affair while he was trapped in the mine. His mistake might cost him his marriage, but it could help pad his wallet and make his days as a miner a thing of the past.

On Monday, controversial website AshleyMadison.com offered Barrios $100,000 to be the site's Spanish-speaking spokesperson. The website provides an online dating service to those looking to have extramarital affairs.

The contract would require Barrios to star in television commercials, radio ads, and to make public appearances in North, South and Central America. He must also remain married to his current wife.

Barrios has not yet indicated whether or not he'll go for the deal.

Sheyla Hershey of Houston, Texas broke the world record when she got breast implants in a size 38KKK. The Brazilian model has had over 30 breast augmentations over the years, and the one she most recently had is likely to force her to relinquish her reign as the world's largest-breasted woman.

Hershey flew to her native Brazil to have another breast surgery in June. Unfortunately, she contracted a severe staph infection in both of her breasts. She returned to Texas for medical assistance and the doctor there said that she would be in danger of death if the infection spread.

An aggressive course of antibiotics has helped stop the infection in one breast, but hasn't worked on the other. Yesterday, she underwent surgery to have the latest implants removed.

She's not out of the woods yet, but if she pulls through and beats the infection maybe she'll learn her lesson and cool on the implants. If it's not already obvious, getting cosmetic surgery that a US doctor wouldn't do in Brazil is a really bad idea.

Former WBA super-featherweight and WBC lightweight champion Edwin Valero took his own life after he was arrested on suspicion of murdering his wife. Venezuelan police told a local newspaper that an inmate heard unusual noises coming from Valero's cell and called for help.

Valero, 28, was found trying to hang himself with his clothes and later died from his injuries. The incident occurred at 1:30am local time. He had been due in court for his murder charge at 9:00am Monday.

It wasn't Valero's first run-in with the law. He has had numerous brushes with the law in the past, which has threatened to derail his career, and was said to have admitted stabbing his wife Jennifer, 24, in Valencia.

In his eight-year boxing career, Valero knocked out each of his 27 opponents and recently gave up the WBC belt. He was hoping to step into the big time with a potential mega-fight against the winner of Floyd Mayweather vs. Shane Mosley.

A 7.2-magnitude earthquake struck the South American country of Chile, just minutes before Sebastian Pinera was sworn in as president. The tremor was centered in O'Higgins Region about 90 miles south of the city of Valparaiso where the inauguration took place. It was the largest aftershoc since February's devastating 8.8-magnitude quake. Shortly after the inauguration, the National Congress building was evacuated and a tsunami alert was issued for coastal areas.

Pinera's presidency marks the end of two decades of left-wing rule in the country. He takes over for the highly-popular Michelle Bachelet, who left office with an 84% popularity rating. As president, Pinera now faces the additional challenge of reconstruction. The February quake and resulting tsunami killed more than 500 people, and left more than 500,000 homeless.

On Sunday, Chile's president sent the army to help police battle looting in the city of Conception, which was hit hard after an earthquake and tsunami devastated cities. President Michelle Bachelet also made an appeal for international help, and announced that the death toll was now at 708 people - double the estimate from Saturday.

Bachelet also said that Chile would accept some of the offers of aid that have poured in from around the world, and said that the country needs field hospitals and temporary bridges, water purification plants and damage assessment experts, in addition to rescuers to help relief workers who have been frantically working for more than a day now.

Along several hundred miles of Chile's central and southern coast, towns have been reporting massive damage from the tsunami that came after the 8.8 magnitude quake. Maule, a region south of the capital city of Santiago, has the most confirmed deaths so far at 504.

Jacqueline van Rysselberghe, mayor of Concepcion, said that the situation in her city was getting "out of control" due to shortages of basic supplies. In the coastal towns of Pelluhue and Constitucion, 350 deaths have been reported and television images showed cars tossed atop homes and boats lifted far from the waterfront.
