Are the chemicals we encounter every day making us sick?
When her kids were young, Tracey Woodruff, PhD, MPH, knew more than most people about environmental toxics. After all, she was a senior scientist at the Environmental Protection Agency (EPA). But even she never dreamed, as she rocked her children to sleep at night, that the plastic baby bottles she used to feed them contained toxic chemicals that could leach into the warm milk.

Sulforaphane in broccoli sprouts found to improve glucose levels in diabetics
A team of researchers from Sweden, the U.S. and Switzerland has found that treating rat liver cells with a compound called sulforaphane, which is found in cruciferous vegetables, reduced production of glucose. In their paper published in Science Translational Medicine, the group outlines the methods they used to isolate the compound and what they found when testing it with liver cells and in human patients.

Women with past adverse childhood experiences more likely to have ovaries removed, study shows
Mayo Clinic researchers report that women who suffered adverse childhood experiences or abuse as an adult are 62 percent more likely to have their ovaries removed before age 46. These removals are for reasons other than the presence of ovarian cancer or a high genetic risk of developing cancer, says the new study published today in BMJ Open.

Listening to the signals
If something tickles our nose, we sneeze. Behind this simple biological output lies a cascade of cell communication. In an interview with uni:view, Manuela Baccarini, molecular biologist at Max F. Perutz Laboratories, explains why cell signaling resembles a WhatsApp group and how we can prevent cell damage.

People perceive attractive scientists as more interesting but less able, studies show
If you think of good science communicators, it's likely that the names Brian Cox, Alice Roberts or Neil deGrasse Tyson may come to mind. But do you consider them good science communicators because they look competent or because they are attractive?

Will short-term and long-term treatments for single-gene diseases survive?
Two weeks and several political disasters ago, the House of Representatives passed the American Health Care Act of 2017, and soon lists of "pre-existing conditions" festooned news feeds. We all ticked off a few. But the lists, although acknowledged as incomplete, offered a highly inconsistent menu of maladies as broad as "cancer" yet as specific as "cystic fibrosis." I don't know whether the focus on the familiar reflects editorial choices to appeal to the masses, or ignorance of or deliberate avoidance of mentioning many of the lesser-known rare diseases. More than 30 million people in the US have rare diseases, many of them genetic and some of those treatable with approaches more complex than those used for more common conditions.

Everyday chemicals may affect brain development, including foetal IQ
All vertebrates – from frogs and birds to human beings – require the same thyroid hormone to thrive. Every stage of brain development is modulated by thyroid hormone and, over millions of years, the structure of this critical hormone has remained unchanged.

Large data set brings precision to breast cancer diagnosis and care
Although the odds of developing breast cancer are nearly identical for black and white women, black women are 42 percent more likely to die from the disease. This mortality gap - driven by social and environmental, as well as biological factors - continues to persist.

Feeling worn out? You could have iron overload
Feeling a bit tired and worn out? Vague symptoms like these are common in iron deficiency and anaemia. But before you reach for the iron supplements or chow down on steak, these symptoms are common in another condition related to iron. This time the trouble is too much iron, not too little, because of the iron overload disorder called haemochromatosis.
