Saltwater crocodiles have the strongest bite of any living animal, research has shown. The huge reptiles, which can measure more than 20ft, have jaws that snap shut with a force of 3,700lb, or almost two tons. In comparison, the great white shark has a chomping capacity of 2,095lb at the tip of its jaws. The spotted hyena has the highest recorded bite force in a mammalian carnivore, at just over 1,000lb. Scientists measured the bite forces and tooth pressures of all 23 living crocodilian species, including crocodiles, alligators, caimans and gharials.

Eating junk food may reduce a man's sperm count, research has shown. A study of men attending a US fertility clinic found those with the fattiest diets produced significantly less sperm. Their sperm density was also lower. The research also showed that diets high in omega-3 fatty acids, found in fish and plant oils, were associated with improved sperm quality. Men were divided into three groups according to how much fat they consumed. Compared with those eating the least fat, men with the highest fat intake had a 43% lower sperm count and 38% lower sperm concentration.

A radio system glitch on one of five small rockets aimed at the edge of space has forced NASA to cancel a barrage of overnight launches tonight that promised to dazzle East Coast skywatchers with glowing midnight clouds.The malfunction was detected as scientists prepared for the late-night launch rocket launches, which were scheduled to blast off within about five minutes of one another at NASA's Wallops Flight Facility on Wallops Island, Va. The initial launch was targeted for 12 a.m. EDT (0400 GMT) on Thursday (March 15).

The remains of what may be a previously unknown human species have been identified in southern China. The bones, which represent at least five individuals, have been dated to between 11,500 and 14,500 years ago. But scientists are calling them simply the Red Deer Cave people, after one of the sites where they were unearthed. The team has told the PLoS One journal that far more detailed analysis of the fossils is required before they can be ascribed to a new human lineage.

A Nasa spacecraft has detected oxygen around one of Saturn's icy moons, Dione.The discovery supports a theory that suggests all of the moons near Saturn and Jupiter might have oxygen around them.Researchers say that their finding increases the likelihood of finding the ingredients for life on one of the moons orbiting gas giants.The study has been published in Geophysical Research Letters. According to co-author Andrew Coates of University College London, Dione has no liquid water and so does not have the conditions to support life.

Researchers scoured the clothes and boots of tourists and scientists visiting the continent and found that most were carrying plant seeds."People in the past have been sceptical, saying, 'It's largely ice-covered so it's unlikely that plants will establish themselves'," said lead researcher Steven Chown from Stellenbosch University in South Africa."[They're] forgetting that probably less than 1%, but still a significant area, is ice-free - some of that's in the peninsula region, and it's been warming very quickly."

Currently, the earth is being showered by a storm of charged particles from the sun. This storm is the largest in five years and it could disrupt power grids, satellite navigation and plane routes. The storm which have been caused by a pair of solar flares earlier this week, will bombard the earth's magnetic field thoughout Thursday. The Sun's activity rises and falls through an 11-year cycle, and has in recent months been seen to launch more of the solar flares that are causing the current storm. The cycle is due to peak in 2013.

Scientists from the US Tevatron accelerator say they have spotted possible hints of the Higgs boson at a mass similar to that seen at the LHC (Large Hadron Collider). The Higgs boson is named after Peter Higgs, an Edinburgh University Physicist. After the Big Bang, it is thought that there were many particles without mass but the Higgs field, upon interaction, gave the particles mass and they became heavy. The Higgs boson is the signature particle of the field.
