Impacts of Too Much Communication

Individuals within a networked system coordinate their activities by communicating to each other information such as their position, speed, or intention. At first glance, it seems that more of this communication will increase the harmony and efficiency of the network. However, scientists at Rensselaer Polytechnic Institute have found that this is only true if the communication and its subsequent action are immediate.

Cassini Dives Inside Saturn’s Radio Aurora

The Cassini spacecraft has made the first observations from within the radio aurora of another planet than Earth. The measurements, which were taken when the spacecraft flew through an active auroral region in 2008, show some similarities and some contrasts between the radio auroral emissions generated at Saturn and those at Earth. Results were presented this week by Dr Laurent Lamy at the European Planetary Science Congress in Rome, and recently published in Geophysical Research Letters.

Hot Atmosphere of Venus Might Cool Interior of Earth’s Sister Planet

The heat in the atmosphere of Venus, induced from a strong greenhouse warming, might actually have a cooling effect on the planet's interior. This counter-intuitive theory is based on calculations from a new model presented at the European Planetary Science Congress (EPSC) in Rome.

3-MILLION-YEAR-OLD WHALE AT THE SAN DIEGO ZOO

Workmen constructing a storm water equalization tank this week at the San Diego Zoo dug up a surprising find: a 3-million-year-old whale.
The construction crew was using an excavotor to dig through fine grain sand, when suddenly the machine struck a solid item. Further investigation revealed that this obstacle was an enormous prehistoric whale.The 24-foot baleen whale appears to be very well preserved, with much of the fossilized skeleton present. Finding an intact skull, along with the vertebrae and flippers, is quite rare, according to Sarah Siren, San Diego Natural History Museum paleontological field manager.
