Dinosaurs Done In By... Dark Matter? 135

Posted by Unknown Lamer
from the mysterious-forces dept.
bmahersciwriter writes "Theoretical physicists propose that the Sun periodically crosses into a dense layer of dark matter sandwiching the Milky Way. The gravitational push and pull that this creates disturbs debris in the Oort cloud sending deadly comets and asteroids ricocheting around the solar system. This passage happens, their admittedly speculative model suggests, every 35 million years, which jibes somewhat with evidence on impact craters. Take it with a dino-sized grain of salt."

+ - Bloomberg Reporters Caught Spying on Terminal Users

Submitted by theodp
theodp (442580) writes "Big Bloomberg is watching you. CNN reports that was the unsettling realization Goldman Sachs execs came to a few weeks ago when a Bloomberg reporter inadvertently revealed that reporters from the news and financial data provider had surveillance capabilities over users of Bloomberg terminals. 'Limited customer relationship data has long been available to our journalists,' acknowledged a Bloomberg spokesman. 'In light of [Goldman's] concern as well as a general heightened sensitivity to data access, we decided to disable journalist access to this customer relationship information for all clients.' Business Insider is now reporting on allegations that Bloomberg reporters used terminals to spy on JPMorgan during the 'London Whale' disaster; Bloomberg bragged about its leadership on this story."

+ - Hubble Discovers 'Planetary Graveyard'->

Submitted by astroengine
astroengine (1577233) writes "The Hubble Space Telescope has discovered rocky remains of planetary material ‘polluting’ the atmospheres of two white dwarfs — a sign that these stars likely have (or had) planetary systems and that asteroids are currently being shredded by extreme tidal forces. Although white dwarfs with polluted atmospheres have been observed before, this is the first time evidence of planetary systems have been discovered in stars belonging to a relatively young cluster of stars. “We have identified chemical evidence for the building blocks of rocky planets,” said Jay Farihi of the University of Cambridge in a Hubble news release. “When these stars were born, they built planets, and there’s a good chance that they currently retain some of them. The signs of rocky debris we are seeing are evidence of this — it is at least as rocky as the most primitive terrestrial bodies in our Solar System.”"

What Struck Earth in 775? 344

Posted by samzenpus

ananyo writes "Just over 1,200 years ago, the planet was hit by an extremely intense burst of high-energy radiation of unknown cause, scientists studying tree-ring data have found. The radiation burst, which seems to have hit between 774 and 775, was detected by looking at the amounts of the radioactive isotope carbon-14 in tree rings that formed during the 775 growing season in the Northern Hemisphere. The increase in 14C levels is so clear that the scientists conclude that the atmospheric level of 14C must have jumped by 1.2% over the course of no longer than a year, about 20 times more than the normal rate of variation (abstract). Yet, as the only known events that can produce a 14C spike are supernova explosions or giant solar flares, and neither event was observed at the time, astronomers have a cosmic mystery on their hands."

There is truly no such thing as personal property anyway.... particularly real estate. Fail to pay property tax and you'll be out on the street same as if you fail to pay rent. They may call it something different, but it is the same in effect and result: don't pay your rent, out you go.
