Ultra-processed foods could damage your brain: studyOctober 15|Duration 2:00New Canadian research suggests that eating too many ultra-processed foods, such as soda, chips and processed meats, could damage your brain. Researchers urge Canadians to cut down on such products. Most people have food in their fridges and cupboards that they know aren't the healthiest choice. A box of chocolate chip cookies you grab for a bedtime snack. Instant noodles for when you can't be bothered to make dinner. Or that bag of ketchup chips you grabbed on a late night stroll home from the bar. But it's not just guilty pleasures. Nearly half of the calories Canadians consume — 45.7 per cent on average, according to Statistics Canada — comes in the form of ultra-processed foods (UPFs) and includes everything from breakfast cereals to frozen meals. Over the years, research has shown that UPFs can negatively impact everything from our weight to our cardiovascular health, and could even be linked to some types of cancer. What are the ultra-processed foods we eat and why does it matter to our health?

A research group at Hosei University in Japan has identified a mechanism by which the bacterium Escherichia coli recognizes metabolic products of bifidobacteria. As News-Medical reports, this may explain how less abundant bacterial species coexist in the gut microbiome and maintain its diversity. Chemical signaling between bacteriaBifidobacteria break down complex carbohydrates, including human milk oligosaccharides, and release metabolic byproducts into the environment. Scientists found that E. coli can detect some of these molecules through specialized sensing systems and prepare its own metabolism accordingly. The authors called this process “metabolic eavesdropping.”The research team tested 54 E. coli transport systems associated with 61 carbon sources. As a result, they determined that the bacterium uses the Uhp and Idn sensing systems to respond to a set of metabolites released by bifidobacteria. More current news is available on the UA.

The role of glucose-6-phosphateThe researchers paid particular attention to the Uhp system, which recognizes and transports hexose phosphates, including glucose-6-phosphate.

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Explanation: Scientists are melting holes in the bottom of the world. In fact, almost 100 holes melted near the South Pole are now being used as an astronomical observatory. Astronomers with the IceCube Neutrino Observatory lowered a long string knotted with basketball-sized light detectors into each vertical lake. The water in each hole soon refreezes. The detectors attached to the strings are sensitive to blue light emitted in the surrounding clear ice. Such light results from fast-moving secondary particles liberated when high-energy neutrinos emitted by powerful processes out in the universe collide with ice molecules. IceCube has now detected many illuminating neutrinos. Pictured in 2010, one of the last of IceCube's detector strings is lowered into the freezing abyss, making IceCube the largest neutrino detector ever created. In recognition of unprecedented discoveries, it was announced earlier this week that a founding leader of the IceCube Collaboration will be awarded the Nobel Prize in Physics.
