No more seasonal hurricane predictions from Colorado State University.

No more seasonal hurricane predictions from Colorado State University.

They lost their funding, which is no surprise.

At the beginning of this year’s season, the team predicted 18 named storms. Nine of those, it said, would become hurricanes. Four would be major hurricanes. Here’s how it shook out: There were 13 named storms. Only two became hurricanes. Neither was a major hurricane.

They, like NOAA, expected an increase in extreme hurricanes and were wrong. In fact, they were so wrong that they illustrated clearly how much a guess all of these climate predictions are. You might as well flip a coin.

Though this conclusion is not final, it appears that Comet ISON was destroyed today in its close fly-by of the Sun.

Though this conclusion is not final, it appears that Comet ISON was destroyed today in its close fly-by of the Sun.

A sad end to what has been a cometary disappointment. First spotted while it was very far from the Sun, astronomers thus hoped that Comet ISON would blaze brightly when it got closer. Instead, it hardly brightened at all during its journey inward, barely reaching naked eye visibility in the last week. Now it appears to be gone forever.

Scientists will gain some knowledge from this comet, as it was a first time visitor to the inner solar system and thus provides information about the solar system’s beginnings. Nonetheless, for those of us that enjoy watching the beautiful things the heavens give us, this comet will always remain a dud.

A new housecat-sized feline species has been discovered in Brazil.

A new housecat-sized feline species has been discovered in Brazil.

Oncillas are housecat-size felines found throughout much of South America, and are also known as little tiger cats, little spotted cats or tigrinas. But not all oncillas are the same: New research suggests that little tiger cats in northeastern Brazil belong to a different species from those elsewhere on the continent, although they look virtually identical.

Researchers analyzed the genetic material of oncillas in northeastern Brazil, and compared them with nearby populations in the south. They found that there was no flow of genes between the two populations of oncillas, and hasn’t been any for millennia, according to the study, published today (Nov. 27) in the journal Current Biology.

This, along with other genetic differences, led researchers to conclude the two populations do not interbreed and are in fact different species, said study co-author Eduardo Eizirik, a researcher at Pontifical Catholic University of Rio Grande do Sul in Brazil.

Comet ISON makes its close flyby of the sun today.

Comet ISON makes its close flyby of the sun today.

Three possible fates await Comet ISON, according to Don Yeomans, manager of NASA’s Near-Earth Object Program Office at the agency’s Jet Propulsion Laboratory in Pasadena, Calif.

“It could be tough enough to survive the passage of the sun and be a fairly bright naked-eye object in the early morning sky in the first week of December,” Yeomans said in a statement. “Or, the sun could actually pull it apart. The tidal forces could actually pull this comet apart and so it becomes several chunks rounding the sun and putting on a great show again in early December. Or, if the comet is very weak, it could break up into a cloud of dust and be a complete bust in December.”

So far the comet has been a big disappointment in terms of brightness. However, its flyby today will be interesting as scientists will get a chance to observe one of the largest sun-grazers they’ve ever seen do this.
