A team of researchers has developed a new model to study the motion patterns of bacteria in real time and to determine how these motions relate to communication within a bacterial colony.

The researchers chemically attached colonies of Escherichia coli bacteria to a microcantilever – a microscopic beam anchored at one end, similar to a diving board – thus coupling its motion to that of the bacteria. As the cantilever itself isn't doesn't generate any vibrations, or 'noise,' this allowed the researchers to monitor the colony's reactions to various stimuli in real time.

For lovers of wild foods, autumn means things like mushrooms and fungi of dizzying variety.

Intrepid treasure hunters scour the woods in search of delectable wild mushrooms and their not-quite-meat, not-quite-vegetable qualities.

A bonus: If you find some, you may be eating something not even known to science.

The Fungi Kingdom is enormously diverse and completely under-documented. Species are tough to know, and that is without counting the billions that have gone extinct without us ever knowing about them, but of the 10 million species likely out there, only about 100,000 have been described.

Are you being recorded? Thanks to the ubiquity of CCTV and camera phones, the answer is more than ever before likely to be “Yes”. Add to this the growth of wearable technology such as Google Glass and people are increasingly exposed to devices that can monitor and record them, whether they realize it or not.

(Inside Science TV) – One of the deadliest forces on earth is the humble mosquito. Mosquito-borne diseases like malaria, chikungunya, yellow fever and West Nile virus infect more than 350 million people and kill another 1 million people every year.

Now, scientists in Florida hope to wipe out some of these deadly diseases by genetically modifying their winged carriers.

“Mosquitoes are probably the most dangerous animal in the world. More people are killed by them [than] by anything else," said Michael Doyle, an entomologist at the Florida Keys Mosquito Control District in Key West, Florida.

That DNA makes RNA which makes protein is a simplified explanation molecular biologists use to explain for how genetic information is deciphered and translated in living organisms.

The process is more complicated than the schema first articulated nearly 60 years ago by Nobel Laureate Francis Crick, co-discoverer of the DNA's double-helix structure. Now it is known that there are multiple types of RNA, three of which—messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA)—are essential for proper protein production. Moreover, RNAs that are synthesized during the process known as transcription often undergo subsequent changes, which are referred to as "post-transcriptional modifications."

After four months of frenzy by over 1500 teams, the very successful Higgs Challenge launched by the ATLAS collaboration ended yesterday, and the "private leaderboard" with the final standings has been revealed. You can see the top 20 scorers below.

If we get sugars down to 3% of total energy intake, it may put dentists out of business, according to a paper in BMC Public Health which analyzed the effect of sugars on tooth decay and found that sugars are the only cause of tooth decay in children and adults.

Free sugars are defined by the World Health Organisation Nutrition Guidance Advisory Group as "Free sugars include monosaccharides and disaccharides added to foods by the manufacturer, cook or consumer, and sugars naturally present in honey, syrups, fruit juices and fruit concentrates." 

Calculating the pros and cons is a time-honored method for making analytical decisions but focusing too much on numberscalculations, especially those involving money, can lead to negative consequences, including social and moral transgressions, says a new paper.

Based on several experiments, researchers concluded that people in a "calculative mindset" as a result of number-crunching are more likely to analyze non-numerical problems mathematically and not take into account social, moral or interpersonal factors.

The Obama administration has proposed several ad hoc multi-country economic agreements, and in doing so has abandoned de facto the World Trade Organization (WTO) as insufficiently malleable to its interests. The two most important of these are the Trans-Pacific Partnership (TPP) and the more recent Transatlantic Trade and Investment Partnership (TTIP).
