North Korea has miniaturised nuclear warheads and made them small enough to fit on ballistic missiles, Japan believes.
Tokyo defence chiefs warn in a new white paper that North Korea’s military activities pose a ‘serious and imminent threat’.
In last year’s report Japan said it was ‘possible’ that North Korea had achieved miniaturisation, but Tokyo now appears to have upgraded its assessment, according to Japanese newspaper Yomiuri.
A MASSIVE asteroid comparable to the massive space rock which brought the dinosaurs’ reign on Earth to an end is hurtling towards Earth, and scientists have confirmed it is “potentially hazardous”.
Even the fallout from a Triassic nuclear war would have vanished without a trace by now.
There are some extinct species — such as the woolly mammoth, shown above — that may be brought back to life if scientists can overcome some practical hurdles and thorny ethical questions. This gallery shows six of the species that researchers talked about reviving at a March 2013 forum called TEDxDeExtinction in Washington, D.C.

Thylacines, or Tasmanian tigers, were found throughout most of the Australian island of Tasmania before Europeans settled there in 1803.
In the future, we may have to deal with biological weapons that target specific groups of people, passing over everyone else.
That’s according to a new report out of Cambridge University’s Centre for the Study of Existential Risk reviewed by The Telegraph. In it, the Cambridge researchers argue that world governments have failed to prepare for futuristic weapons based on advanced technology like artificial intelligence and genetic manipulation — or even a killer pathogen designed to kill only people of a particular race.
The asteroid managed to get within just 73,000 kilometers of our planet without anyone noticing. The miss lends a new sense of urgency to preparations for a potential collision one day.
The news: On Thursday July 25 an asteroid dubbed “Asteroid 2019 OK”, measuring 57 to 130 meters wide (187 to 427 feet), got uncomfortably close to Earth, according to NASA’s near-Earth objects database. It was less than one-fifth of the distance to the moon away, making it a very close call in space terms. If it had landed on a populated area it could have caused major damage, although this outcome is statistically quite unlikely.
Should we worry? It’s hard not to feel concerned that a “city-killer” sized asteroid wasn’t detected further ahead of time. It was announced just hours before it passed by Earth, after being detected just a few days beforehand by teams in the US and Brazil. Its relatively small size, unusual orbit, and fast speed all conspired to make it tough to spot, researchers told the Washington Post.
Now, it seems this nascent industry’s time has come. A growing demand for batteries to power electric cars and to store wind and solar energy has driven up the cost of many rare-earth metals and bolstered the business case for sea-bed mining. What’s more, the industry’s long-awaited regulations — in the form of a mining code — are due to be finalized by 2020, putting in place a process whereby contractors can apply for 30-year licences to mine assigned ‘claim areas’ in parts of the international sea bed such as the CCZ. Already, miners are exploring the potential wealth of these claim areas, but no commercial extraction will begin until the regulations are in place. Investments in this industry are now growing.
Plans are advancing to harvest precious ores from the ocean floor, but scientists say that companies have not tested them enough to avoid devastating damage.
The Earthwatch Institute concluded in the last debate of the Royal Geographical Society of London, that bees are the most important living being on the planet, however, scientists have also made an announcement: Bees have already entered into extinction risk.

Larger animals are at greater risk of extinction as relentless human pressure on their habitats takes its toll.

The world’s insects are disappearing. If we don’t stop it, this disappearance will set off a catastrophic chain of events. #YEARSproject
