Harvard bioethicist shares hope, concerns on gene-editing
The announcement by Oregon Health & Science University that scientists there had edited the genes of human embryos to remove the cause of a deadly disease has raised the prospect of a powerful new tool for physicians—as well as fears of a Pandora's Box that could lead to "designer babies" and humans engineered for desirable traits such as strength or intelligence.

Opinion: Why we should be worried about gene-carrier screening
The ability to cheaply and quickly sequence entire genomes is changing the way diseases are identified and treated. But it is also likely to change the way we make some of the most important and personal decisions of our lives: how, and with whom, we have children.

Idhifa approved for some with acute myeloid leukemia
(HealthDay)—Idhifa (enasidenib) has been approved by the U.S. Food and Drug Administration to treat adults with a specific genetic mutation that leads to relapsed or refractory acute myeloid leukemia (AML).

Concussions and CTE—more complicated than even the experts know
For many, American football is a beautiful game that is simple to enjoy but complex to master. Choreographed with a mixture of artistry and brutality, it features the occasional "big hit" or bone-jarring tackle, forcing a fumble and turning the tide of the game.

Public trust in science spiked after media coverage of Zika vaccine trial
How can the public's confidence in science be strengthened? Public trust in science has largely held steady for decades, despite short-term fluctuations. But new findings based on a survey of public attitudes toward the Zika vaccine suggest that there is a way to increase public support for science.

Terminally-ill British baby Charlie Gard dies
Charlie Gard, the terminally-ill British baby whose plight drew sympathy from Pope Francis and US President Donald Trump and sparked a debate about medical ethics, died on Friday, his mother said.

Faster diagnosis of inherited and lethal nerve disease could advance search for new treatments
Johns Hopkins physicians report success in a small study of a modified skin biopsy that hastens the earlier diagnosis of an inherited and progressively fatal nerve disease and seems to offer a clearer view of the disorder's severity and progression. With a quicker and less invasive way to visualize the hallmark protein clumps of the rare but lethal disease—familial transthyretin amyloidosis—the researchers say they hope to more rapidly advance clinical trials of treatments that may slow the disease and extend patients' lives.

Cancer hijacks natural cell process to survive
Cancer tumours manipulate a natural cell process to promote their survival suggesting that controlling this mechanism could stop progress of the disease, according to new research led by the University of Oxford.

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.
