There are lots of diagnostic tests available outside of the conventional medical system and those include tests for food intolerance, like vega testing, kinesiology, hair "body field analysis" testing, cytotoxic and live blood testing. 

Doctors and medical practitioners can be justified in assuming the worst and dismissing test results that originate from services such as 'mail order laboratory testing services', as there is no way for them to distinguish between those results which have an evidence basis with clinical data and those that claim results without any real evidence. 

NASA's Cassini spacecraft has been orbiting Saturn since 2004 so it has seen a lot - but it recently saw something that has not happened since 1997.

Seasonal atmospheric circulation direction changes on Titan, technically only a moon but bigger than the planet Mercury, happen only once every 15 years and are never observable from Earth. Titan is the only known moon to have a significant atmosphere and is one of only four terrestrial atmospheres in our Solar System - the others being Venus, Mars and obviously Earth. Since Titan's rotation axis is tilted similar to Earth, it experiences seasons in a similar way, they just take a lot longer, because Saturn takes 29.5 Earth years to orbit the Sun.

A few years ago, my wife had a milestone birthday and decided she wanted to run a marathon.  Now, I don't even like to drive 26 miles much less run that far - that Greek guy is famous because he died doing it and there are some experiments I don't need to replicate in order for them to have my full acceptance.

But my wife wanted to do it. I had never seen her so much as walk fast but she signed up with a group called Team In Training and off she went (1) - they have various morale-building events, including dinners, and at one of those I met a fellow marathon husband and he said, "You kind of look like that guy on "Burn Notice".

Astronomers have discovered vast comet belts surrounding two nearby planetary systems – GJ 581 and 61 Vir – known to host only Earth-to-Neptune-mass worlds.   Previously, scientists found that the dusty belt surrounding nearby star Fomalhaut must be maintained by collisions between comets. 

Archaeologists have discovered the remains of a fleet of early-19th century ships and ancient harbor structures from the Hellenistic period at the city of Akko (Acre), one of the major ancient ports of the eastern Mediterranean and one of the oldest continuously inhabited cities in the world, they revealed at the annual meeting of the American Schools of Oriental Research.

Bread wheat (Triticum aestivum) accounts for 20% of the calories consumed by the entire world and is one of the Big Three globally important crops, along with rice and corn. 

A jet of X-rays from the supermassive black hole in quasar
GB 1428+4217, 12.4 billion light years from Earth, has been detected by NASA's Chandra X-ray Observatory - the most distant X-ray jet ever observed. 

Giant black holes at the centers of galaxies can pull in matter at a rapid rate producing the quasar phenomenon. The energy released as particles fall toward the black hole generates intense radiation and powerful beams of high-energy particles that blast away from the black hole at nearly the speed of light. These particle beams can interact with magnetic fields or ambient photons to produce jets of radiation. 

Millions of years ago, tiny animal thieves going by the alias protozoa held algae captive and then exploited and stole their genes for energy production, thereby evolving into a new and more powerful species.

But the little protozoan outlaws couldn't completely hide all evidence of the captive algae and have been effectively frozen in time - and then caught in the act by genetic sequencing. 

The protozoa captured genes for photosynthesis, the process of harnessing light to produce energy which is used by all plants and algae on earth. Scientists assume that quantum leaps of evolution occurred by one organism cannibalizing another, but hard evidence is rare.

When it comes to the number of pieces of information the mind can cope with before confusion sets in, the "magic" number is seven, psychologists have long said.  But did phone companies pick that because of the claim or did folk wisdom say it must be seven because that is what phone companies used?

In 1956, American psychologist George Miller published a paper, "The Magical Number Seven, Plus or Minus Two. Some Limits on Our Capacity for Processing Information", in Psychological Review, arguing the mind could cope with seven chunks of information.

Temperature rises are consistent with projections made in the IPCC's fourth assessment report (AR4) but satellite measurements show that sea levels are rising at a rate of 3.2 mm a year compared to the best estimate of 2 mm a year in the report, about 60 percent faster, says a new report. 

They used an analysis of global temperatures and sea-level data over the past two decades, comparing them both to projections made in the IPCC's third and fourth assessment reports. Results were obtained by taking averages from the five available global land and ocean temperature series.
