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.

Researchers produce molecules with potential against HIV
As the HIV/AIDS epidemic approaches its fourth decade, each year brings promising news of pioneering research to alleviate the scourge. Add City College of New York scientists to the list with a rapid method to access new molecules that could inhibit the virus that causes AIDS.

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.

Scientists discover rare genetic susceptibility to common cold
Scientists have identified a rare genetic mutation that results in a markedly increased susceptibility to infection by human rhinoviruses (HRVs)—the main causes of the common cold. Colds contribute to more than 18 billion upper respiratory infections worldwide each year, according to the Global Burden of Disease Study .

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.

New drug approved for all cancers with genetic marker
(HealthDay)—Keytruda (pembrolizumab) has been approved by the U.S. Food and Drug Administration to treat any cancer that has a certain genetic biomarker, regardless of where in the body the cancer originated.

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.

Brineura approved for rare genetic illness affecting kids
(HealthDay)—Brineura (cerliponase alfa) has been approved by the U.S. Food and Drug Administration to treat a specific form of Batten Disease, a rare set of genetic disorders that typically begin in childhood between ages 2 and 4, the agency said in a news release.

Novel phage therapy saves patient with multidrug-resistant bacterial infection
Scientists and physicians at University of California San Diego School of Medicine, working with colleagues at the U.S. Navy Medical Research Center - Biological Defense Research Directorate (NMRC-BDRD), Texas A&M University, a San Diego-based biotech and elsewhere, have successfully used an experimental therapy involving bacteriophages—viruses that target and consume specific strains of bacteria—to treat a patient near death from a multidrug-resistant bacterium.

'Junk food' and the consumer blame game
People in the UK are hooked on takeaways and microwave meals, or so we are constantly told by TV chefs and the media. This apparent addiction to fast food is leading to an obesity epidemic.

Expert endorses genetic testing for BRCA1 and BRCA2
Professor Kelly Metcalfe, of U of T's Lawrence S. Bloomberg Faculty of Nursing, is leading the charge against hereditary breast and ovarian cancers by helping establish the standard protocol for addressing cancers associated with BRCA gene mutations.

Epilepsy breakthrough: Implant helps stop brain seizures
Imagine a seismograph - the instrument that measures and records earthquakes and volcanic eruptions - for your brain. Except this one has a wireless link to a device implanted in your head that stops epileptic seizures at their source, halting the sudden and violent attacks before they happen.
