Possible health risks make Bumble Bee Foods and Tri-Union Seafoods to voluntarily recall canned chunk light tuna. The company informed in an official statement, “These deviations were part of the commercial sterilization process and could result in contamination by spoilage organisms or pathogens, which could lead to life-threatening illness if consumed”. So far, there is no report of any illness related to the recalled tuna.

As per Steve Mavity, Bumble Bee's senior vice president, technical services and corporate quality, the recalls are linked. Mavity said that Bumble Bee has recalled some particular codes of canned Chunk Light Tuna that have been produced in Chicken of the Sea's Georgia production facility. It is Bumble Bee’s third-party supplier.

On Thursday, the local authorities informed that two people have tested positive for Ebola in Guinea. The confirmation has come months after the outbreak was declared over in the West African country and hours after Sierra Leone declared that the recent flare-up of the virus has come to an end there.

Ibrahima Sylla, spokesman for the national coordination for the fight against Ebola, said that the cases belong to the same family in Koropara, located in the N’Zerekore region, roughly 1,000 kilometers southeast of Conakry, Guinea’s capital.

Sylla said that there are three other likely cases, and health authorities have taken important measures to restrict the spread.

Astronomers using the Very Large Array (VLA) have come up with new images of a young star, revealing what scientists think could be the quite initial stages in the planets’ formation.

The VLA has been used by scientists to witness extraordinary details of the inside part of a dusty disk present around the star, at a distance of around 450 light-years from Earth.

In 2014, scientists used Atacama Large Millimeter/submillimeter Array (ALMA) to study the star and its disk, and at that time, it produced what astronomers dubbed as the best photograph ever, depicting planet formation in progress.

As part of a new proposal, Guantánamo Bay Naval Base, which includes the well known detention center, could be changed into a marine conservation area and an international peace park, once the inmates vacant it.

Appeared in the journal Science on Thursday, the proposal indicates that the fate of the base could depend on the decision taken by authorities. The relations between Cuba and the United States have improved recently. President Obama’s will soon make a historic visit to Cuba.

In a telephone interview with The Christian Science Monitor, co-author Joe Roman, a conservation biologist at the University of Vermont, said, the US embassy in Cuba is open, with which more business will knock, and tourists will step in, putting more pressure on coastal systems in the coming time.

Paleontologists have claimed that they have unearthed a prehistoric creature trapped in a stone. The ancient animal has a pincer-tipped nose, sharp needle-teeth and eyes on a slim stalk. It has been dubbed: Tully monster.

For nearly 60 years, the bizarre Tullimonstrum gregarium fossils have been troubling paleontologists. So far, the creature hasn’t fit into any known major animal group.

As per a new report published in the journal of Nature this week, scientists think they have solved the Tully monster mystery and its position on the tree of life.

The fossils have been found in a 300-million-year-old rock. They were discovered by the dozens in 1958 with in Illinois coalmines.

Modern human’s ancestors interbred with Neanderthals and another species of early humans on multiple occasions, as per a new study. It suggests our ancestors interbred with Neanderthals and Denisova hominin on at least four separate occasions in the past.

Our improved immunity to pathogens is the result of that prehistoric mating, said the study authors. “This is yet another genetic nail in the coffin of our over-simplistic models of human evolution”, said Carles Lalueza-Fox of the Institute of Evolutionary Biology. Lalueza-Fox wasn’t part of the study.
