A new species of large predatory fish named Laccognathus embryi that prowled ancient North American waterways during the Devonian Period, before backboned animals existed on land, has been announced.The Devonian Period (415 to 360 million years ago) is often described as the Age of Fishes because of the rich variety of aquatic forms that populated the ancient seas, lagoons and streams. Laccognathus embryi is a lobe-finned fish whose closest living relative is the lungfish. The creature probably grew to about 5 or 6 feet long and had a wide head with small eyes and robust jaws lined with large piercing teeth.

With a ban on incandescent bulbs looming in the US, the race is on to try and replace them - unfortunately the ban was used to artificially force innovation, which isn't how things work in science and technology, and CFL bulbs have mercury risk while concerns linger about LEDs and melatonin. 

A genome-based immunization strategy may 'illuminate' ways to combat AIDS and other diseases. Feline immunodeficiency virus (FIV) causes AIDS in cats as the human immunodeficiency virus (HIV) does in people, by depleting the body's infection-fighting T-cells. The feline and human versions of key proteins that potently defend mammals against virus invasion, termed restriction factors, are ineffective against FIV and HIV respectively. A Mayo Clinic team along with collaborators in Japan write in Nature Methods of their efforts to mimic the way evolution normally gives rise over vast time spans to protective protein versions. They devised a way to insert effective monkey versions of them into the cat genome. 

Optofluidic solar lighting systems could mean a real boost in solar energy - they capture sunlight from a roof using a light concentrating system that follows the sun's path by changing the angle of the water's refraction, and then distribute the sunlight throughout the building through light pipes or fiber optic cables to the ceilings of office spaces, indoor solar panels, or even microfluidic air filters.

Every three hours, NASA's Fermi Gamma-ray Space Telescope scans the entire sky. Every year, the satellite's scientists reanalyze all of the data it has collected about the high energy universe.

The Sheriff of Nottingham will be pleased. It only took 800 years, but poachers can now be tracked down through tests for human DNA on deer remains, according to research led by scientists at the University of Strathclyde.Aside from being silly, since most 'poachers' are actually just poor people feeding a family, just like they were in Robin Hood's day, identifying deer poachers can be problematic because these 'crimes' are not discovered until long after the event - and no one cares.  These 'poachers' also field dress the deer carcass (hunters wear gloves) so little human DNA is left behind.

Kepler-19b, which orbits the Sun-like star Kepler-19 650 light-years from Earth in the constellation Lyra, has been found to have an 'invisible' world tugging on it.How do astronomers know, since it's invisible?  Kepler-19b alternately runs late and early in its orbit, the first definite detection of a previously unknown planet using this method. No other technique could have found the unseen companion.  
Kepler-19 is a 12th-magnitude star and can be seen by backyard telescopes on September evenings.

A new alginate binder material for lithium-ion battery electrodes could boost energy storage and perhaps help eliminate the toxic compounds in batteries - good news for Prius owners who are concerned their batteries may be doing more harm to the environment than their emissions are saving.

What did Greenland look like over the last 800,000 years?   Hard to know for sure but one thing is certain; it changed often, and quickly.Drill cores taken from Greenland's vast ice sheets show that Earth's climate is capable of very rapid transitions - more of a mystery is why abrupt climate changes like that happen.Layers of ancient snow accumulated and became compact to form the ice-sheets we see today. Each layer of ice can reveal past temperatures and even evidence for the timing and magnitude of distant storms or volcanic eruptions. By drilling cores in the ice scientists have reconstructed an incredible record of past climates. Those temperature records from Greenland covered only the last 100,000 years or so. 

Brain, pelvis, hands and feet  don't lie - and five recent studies of Australopithecus sediba, a primitive hominin that existed around the same time early Homo species first began to appear on Earth, suggest this ancient relative and its primitive and modern, human-like traits, make it the best candidate for an ancestor to the Homo genus.The discoveries are casting doubt on some long-standing theories about human evolution, including the notion that early human pelvises evolved in response to larger brain sizes. And there is also some new evidence suggesting that Australopithecus sediba may have been a tool-maker.

In football, if you are a lineman, you are going to give and take a lot of hits - but running backs really get punished.  

Whenever a popular television health claim makes its way into the media, some skepticism is in order.  A decade-long war on "trans fats", including outright bans in some areas, was not based on science or objective evidence.
