Mothers should suck their babies’ dummies, scientists say

Being too clean has killed beneficial bacteria and mothers should suck their babies’ dummies to wash them and keep their children healthy, research suggests

Dummies can stunt children's emotional development

According to Prof Graham Rook, children whose mother’s sucked their dummies to clean them were a third less likely to develop asthma and eczema

Mothers should suck their babies’ dummies to clean them, let children eat food from the floor, and get a dog, if they want to keep their families healthy, academics have claimed.

Experts from Cambridge University and University College London said that being too clean has killed beneficial bacteria, which keep the immune system strong.

They also advise frequent walks in the countryside; visiting farms and kissing family members regularly, and exercising in the park rather than at the gym, to top up on healthy bacteria.

Children whose mother’s sucked their dummies to clean them were a third less likely to develop asthma and eczema, Prof Graham Rook, told the Cheltenham Science Festival.

Phone display will kill the Bacteria

Future of phone displays: non-reflective, antimicrobial, made with Corning

We’ve heard that Corning, the maker of Gorilla Glass that protects your smartphone or tablet display, is cooking up something in terms of anti-reflection and anti-microbial abilities, and for the first time the firm gave it some pep talk in public at the MIT Mobile Technology Summit.

Dr. Jeffrey Evenson, senior vice president and operations chief of staff for Corning took the stage and gave the usual demos we’ve seen before like a four-pound steel ball dropping on a 1mm sheet of Gorilla Glass with the proverbial trampoline effect.
Corning reiterated some of the main advantages of its glass technology in the bullet points below:

Cells as living calculators

Cells as living calculators

MIT engineers have transformed bacterial cells into living calculators that can compute logarithms, divide, and take square roots, using three or fewer genetic parts.

Inspired by how analog electronic circuits function, the researchers created synthetic computation circuits by combining existing genetic “parts,” or engineered genes, in novel ways.

The circuits perform those calculations in an analog fashion by exploiting natural biochemical functions that are already present in the cell rather than by reinventing them with digital logic, thus making them more efficient than the digital circuits pursued by most synthetic biologists, according to Rahul Sarpeshkar and Timothy Lu, the two senior authors on the paper, describing the circuits in the May 15 online edition of Nature.

“In analog you compute on a continuous set of numbers, which means it’s not just black and white, it’s gray as well,” says Sarpeshkar, an associate professor of electrical engineering and computer science and the head of the Analog Circuits and Biological Systems group at MIT
