If you are obese, it is reasonably well-established that you are not going to exercise and vibration machines that sound like they might be less work, like the kind developed by the Soviets for astronauts, actually can burn through 400 calories in 15 minutes, so they are not for the casual - but a recent study found that low-intensity vibrations led to improvements in the immune function of obese mice.

If the same effect can be found in people, it would have clinical benefits for obese people suffering from a wide range of immune problems related to obesity.

 Astronomers theorize that an as-yet-unidentified form of matter is responsible for 90 percent of the gravity within galaxies and clusters of galaxies but because it is detected via its gravity and not its light, they call it "dark matter." 

The winners of the 2012 Semantic Web Challenge (SWC), determined by a jury from both academia and industry, were announced at the International Semantic Web Conference held in Boston. The challenge and allocated prizes were sponsored by Elsevier. 

 In 2003, the SWC was set up to showcase the very latest in semantic web technology and every year the final rounds of this competition take place at the annual International Semantic Web Conference. Semantic Web Challenge contestants competed in any of two challenge categories: 'Open Track' and 'Billion Triples Track'. 

A monster black hole has been detected.  With 17 billion solar masses, it is significantly heavier than models predict and could be the most massive black hole known to date. 

 Astronomers believe there is a super-massive black hole at the heart of every galaxy and its mass ranges from several hundred thousand solar masses to a few billion. The black hole that has been best investigated  sits at the center of our galaxy, the Milky Way, and has around four million solar masses.

Merck Serono, a division of Merck, has donated its 100 millionth praziquantel tablet to the World Health Organization (WHO).

People follow patterns. If you were projecting a future for New York City in the early 1980s, you would have rightfully anticipated a Kurt Russell movie where the city is walled off from the rest of the country because the crime problem was rampant. Homicide moves through a city in a process similar to infectious disease, according to a new study that may give police a new tool in tracking and ultimately preventing murders.

Does one’s skull vibrate when chewing biscuits?  The answer is yes, up to a point – that’s according to a recentl experimental study performed by the Department of Oral-Maxillofacial Surgery, Prosthodontics and Special Dental Care Oral Physiology Group, at the University Medical Center Utrecht, The Netherlands, along with the Department of Prosthetic Dentistry, Faculty of Dentistry, Lutheran University of Brazil, Porto Alegre, Brazil.

Evolutionarily speaking, most of the harmful mutations that still exist in people are recent, which makes the case that nature is still out to get us, even in modern times.

A study dated the age of more than 1 million single-letter variations in the human DNA code and revealed that 86 percent of the harmful protein-coding mutations of this type arose in humans just during the past 5,000 to 10,000 years. These kinds of mutations change one nucleotide – an A, C, T or G – in the DNA sequence. 

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.
