Just like checking your bag on a commercial airline, space travel comes with some pretty big weight restrictions.According to estimates, reaching space costs a whopping $10,000 per pound, which means that every ounce saved has a big impact on the bottom line.That's where a group of Danish researchers comes in.

Computers May Spot Deadly Food Poisoning Bacteria

Computers May Spot Deadly Food Poisoning Bacteria

A novel computer software can learn to predict strains of bacteria likely to cause food poisoning outbreaks, a new study has found.Researchers at the University of Edinburgh in the UK used a software that compares genetic information from bacterial samples isolated from both animals and people.The software learns the DNA signatures that are associated with E coli samples that have caused outbreaks of infection in people.It can then pick out the animal strains that have these signatures, which are therefore likely to be a threat to human health.Most E coli strains live in the guts of people and animals without causing illness but E coli O157 is linked with more serious human infections.Cows also carry E coli O157 and serve as the main reservoir for these toxic bacteria.The animals excrete the bacteria in their faeces but do not become ill.This makes it difficult to spot which herds and animals are carrying strains that are likely to cause disease in people.The team trained the software on DNA sequences from strains isolated from cattle herds and human infections in the UK and the US.Once trained, the computer is able to predict whether an E coli strain is likely to have come from a cow or a person.Using this approach, the team predicts that less than 10 per cent of the E coli O157 cattle strains are likely to have the potential to cause human disease.Interventions to stop the spread of the disease - such as vaccines - could be targeted at herds with these strains to minimise the risk of outbreaks in people, researchers said.E coli O157 causes stomach cramps, vomiting and severe diarrhoea in infected people.

Glowing Bacteria Could Improve Food Safety

NewsGlowing Bacteria Could Improve Food SafetyUS - Scientists looking for traces of a type of E. coli bacteria contamination in foods soon could have a new detection method on their hands - turning off the lights to see if the bacteria glow in the dark.Purdue University researchers have engineered a bacteriophage called NanoLuc - a virus that only infects bacteria - to produce an enzyme that causes E. coli O157:H7 to emit light if infected.The process can shave hours off traditional testing methods, which can be critical when stopping the distribution of tainted foods.
