ScentCone writes "North Korea says that it has conducted its first nuclear weapons test and 'brought happiness to its people.' Japan and China earlier issued an unusual joint statement saying that such a test would be 'unacceptable.' As of 11:10PM EST, the USGS says that it has not detected any unusual seismic activity on the Korean peninsula in the last 48 hours." From the article: "The North said last week it would conduct a test, sparking regional concern and frantic diplomatic efforts aimed at dissuading Pyongyang from such a move. North Korea has long claimed to have nuclear weapons, but had never before performed a known test to prove its arsenal. The nuclear test was conducted at 10:36 a.m. (0136 GMT) in Hwaderi near Kilju city, Yonhap reported, citing defense officials." Update: 10/09 05:50 GMT by J : The U.S. Geological Survey reports a 4.2 magnitude quake; South Korean news is reporting a 3.58 magnitude event; the White House apparently confirms a nuclear test.

Krishna Dagli writes to mention a decades-long study by NASA scientists. According to the research, global temperatures are reaching highs not seen in thousands of years. From the article: "One of the findings from this collaboration is that the Western Equatorial Pacific and Indian Oceans are now as warm as, or warmer than, at any prior time in the Holocene. The Holocene is the relatively warm period that has existed for almost 12,000 years, since the end of the last major ice age. The Western Pacific and Indian Oceans are important because, as these researchers show, temperature change there is indicative of global temperature change. Therefore, by inference, the world as a whole is now as warm as, or warmer than, at any time in the Holocene. According to Lea, 'The Western Pacific is important for another reason, too: it is a major source of heat for the world's oceans and for the global atmosphere.'"

chrisb33 writes to tell us the next iteration of the iPod may talk you through the menus instead of just relying on text. The Scotsman speculates on this new technology based on a patent filed by Apple in the US. From the article: "The patent reveals the idea is driven largely by safety considerations. It states: 'A user will have difficulty navigating the interface in "eyes-busy" situations. Such activities include, for example, driving an automobile, exercising and crossing the street." The patent also makes clear that text-to-speech technology is likely to spread to other hand-held electronic devices such as mobile phones and palm-top computers."

Guglio writes "Eweek has a story about a new, undocumented Excel flaw that is being used in a targeted attack against an unnamed business. The latest zero-day attack comes just two days after Patch Tuesday (coincidence?) and less than a month after a very similar, 'super, super targeted attack' against business interests overseas. The back-to-back zero-day attacks closely resemble each other and suggest that well-organized criminals are conducting corporate espionage using critical flaws purchased from underground hackers."

HUADPE writes to tell us CNN is reporting that scientists in northeastern Ethiopia recently discovered a skull that they think may be evidence of the "missing link" between Homo erectus and modern man. From the article: "The hominid cranium -- found in two pieces and believed to be between 500,000 and 250,000 years old -- 'comes from a very significant period and is very close to the appearance of the anatomically modern human,' said Sileshi Semaw, director of the Gona Paleoanthropological Research Project in Ethiopia."
