Ethical challenges are central to persistent “critical weaknesses” in the national system for ensuring drug safety, according to a commentary by former Institute of Medicine (IOM) committee members published today in the New England Journal of Medicine.
New born human infants have the largest brains among primates, but also the highest proportion of body fat. Before birth, if the supply of nutrients from the mother through the placenta is limited or unbalanced, the developing baby faces a dilemma: should resources be allocated to brain growth, or to fat deposition for use as an energy reserve during the early months after birth? Scientists have shown that this decision could have an effect on how fat we are as children.
With nearly 55 million students, teachers and school staff about to return to elementary and secondary school classrooms, scientists have developed a new hand-held sensor - practical enough for wide use - that could keep classroom air fresher and kids more alert for learning.
When it comes to prostate cancer, there’s a lot of confusion about how to prevent it, find it early and the best way – or even whether – to treat it. Here are six common prostate cancer myths along with research-based information from scientists to help men separate fact from fiction.
The new imaging study in a mouse model for fetal alcohol spectrum disorders could enhance the diagnoses of birth defects caused by alcohol exposure in the womb and it illustrates how the precise timing of that exposure could determine specific kinds of defects.
Northwestern University scientists have connected 250 years of organic chemical knowledge into one giant computer network -- a chemical Google on steroids. This "immortal chemist" will never retire and take away its knowledge but instead will continue to learn, grow and share.
Researchers have identified a gene that disrupts the inflammatory process implicated in liver cancer.
A new study found there was significantly lower quality of care and worse outcomes in women compared to men – particularly young women under age 35 who had heart attack symptoms.
Using bioluminescent proteins from a jellyfish, a team of scientists has lit up the inside of a neuron, capturing spectacular video footage that shows the movement of proteins throughout the cell.
In the case of aggressive fibromatosis, the good news is that it is a slow-growing benign tumor. The bad news is that this abdominal tumor often recurs after surgical removal. This is particularly true among children. While headway has been made in isolating causes of this recurrence in adults, it is less clear in children.
A New York City patient carrying a multi-drug-resistant strain of Klebsiella pneumoniae, a microbe frequently associated with hospital-borne infections, introduced the dangerous bacteria into the 243-bed research hospital while participating in a clinical study in the summer of 2011. To get the outbreak under control, medical researchers used genome sequencing in the middle of this active hospital epidemic to learn how the microbe spread.
Like recruiters pitching military service to a throng of people, scientists are developing drugs to recruit disease-fighting proteins present naturally in everyone’s blood in medicine’s war on infections, cancer and a range of other diseases.
