12/4/14 Health News: GAPS IN FDA’S ANIMAL ANTIBIOTICS POLICY ♦ Nanotubes restore sight♦ How bacteria drill into our cells and kill them ♦ Case against the midnight snack

ANALYSIS HIGHLIGHTS GAPS IN FDA’S ANIMAL ANTIBIOTICS POLICY
A year after the U.S. Food and Drug Administration released its Guidance for Industry #213, analysis by the Pew Charitable Trusts finds that gaps in the animal antibiotics policy could allow for some drugs to be used at the same rate. In order to reduce antibiotic misuse and address the increase in antibiotic-resistant bacteria, FDA... Continue Reading
Nanotubes may restore sight to blind retinas
Retinal degeneration is one of the most worrisome dangers in the aging process. Now researchers have made an important technological breakthrough towards a prosthetic retina that could help alleviate conditions that result from problems with this vital part of the eye Continue Reading

Another case against the midnight snack

These days, with the abundance of artificial light, TV, tablets and smartphones, adults and children alike are burning the midnight oil. What they are not burning is calories: with later bedtimes comes the tendency to eat. A new study cautions against an extended period of snacking, suggesting instead that confining caloric consumption to an 8- to 12-hour period-as people did just a century ago-might stave off high cholesterol, diabetes and obesity.

How bacteria drill into our cells and kill them
A team of scientists has revealed how certain harmful bacteria drill into our cells to kill them. Their study shows how bacterial ‘nanodrills’ assemble themselves on the outer surfaces of our cells, and includes the first movie of how they then punch holes in the cells’ outer membranes. The research supports the development of new drugs that target this mechanism, which is implicated in serious diseases. Continue Reading
