Responsible science is almost always a slow, grueling process, but 20 years after James Thomson derived the first human embryonic stem cell lines, experts in the field of stem cell and regenerative medicine feel more optimistic than ever.
More than 250 million people, mostly in Africa and Asia, have schistosomiasis, which kills an estimated 280,000 each year. “We don’t get that many aha! moments in our lives as scientists,” says a researcher. “This was one of them.”
Often, in order to identify a fatty liver, an invasive liver biopsy is required. Taking a blood sample would be a much simpler way to diagnose it.
Researchers are developing a "robust, simple and inexpensive way to increase the sensitivity of an existing TB test" by integrating a step very similar to a pregnancy test.
Monkeys who catch Zika virus through bites from infected mosquitoes develop infections that look like human Zika cases, and may help researchers understand the many ways Zika can be transmitted.
“Most young people with Friedreich’s ataxia develop severe heart problems and are wheelchair-bound," says researcher Aseem Ansari, "but the disease is so rare that few drug companies invest in it."
The Centers for Disease Control and Prevention (CDC) has awarded $10 million to a consortium of Midwestern universities to establish a new research and training program to stem the spread of disease carried by vectors like ticks and mosquitoes.
Researchers discovered extraordinarily well preserved microfossils — mineralized ‘ghost cells’ — that closely resembled bacteria from the genus Staphylococcus.
