Over the past decade, the CRISPR-Cas9 gene editing system has revolutionized genetic engineering, allowing scientists to make targeted changes to organisms’ DNA. While the system could potentially be useful in treating a variety of diseases, CRISPR-Cas9 editing involves cutting DNA strands, leading to permanent changes to the cell’s genetic material. Now, in a paper published online in Cell,…
Scientific and public health experts have been raising the alarm for decades, imploring public officials to prepare for the inevitability of a viral pandemic. Infectious epidemics seemingly as benign as "the flu" and as deadly as the Ebola virus provided ample warning, yet government officials seemed caught off guard and ill prepared for dealing with Covid-19.
When cancer is confined to one spot in the body, doctors can often treat it with surgery or other therapies. Much of the mortality associated with cancer, however, is due to its tendency to metastasize, sending out seeds of itself that may take root throughout the body. The exact moment of metastasis is fleeting, lost in the millions of divisions that take place in a tumor. “These events are…

Tinnitus, more commonly known as ringing in the ears, is a serious audiological and neurological condition affecting nearly 50 million Americans. Noise and music exposure are the predominant environmental risk factors for tinnitus. There is no known cure, and there are no FDA-approved medications developed specifically to treat it. The fact is, tinnitus is very common but not well understood. A…
In the last six years, a tool called CRISPR-Cas9 has transformed genetic research, allowing scientists to snip and edit DNA strands at precise locations like a pair of tiny scissors. But sometimes, it takes more than scissors to do the job. Now, a collaborative international team has unveiled a new CRISPR-based tool that acts more like a shredder, able to wipe out long stretches of DNA in human…
For some cancers, initial treatment with chemotherapy brings positive, but only temporary, results: tumors shrink, but then rebound as the cancer becomes drug-resistant. This pattern of remission-resistance-relapse is particularly true for pancreatic cancer, an aggressive disease in which early success is often countered by eventual disease progression. To wit: The one-year relative survival rate…
How can we detect the first signs of disease as early as possible? Could closer investigation at the cellular level help to quickly prevent disease progression through appropriate treatment?

For patients with an often-deadly form of leukemia, new research suggests that lingering cancer-related mutations – detected after initial treatment with chemotherapy – are associated with an increased risk of relapse and poor survival.
It may come as a bit of a surprise to learn that bacteria have an immune system – in their case to fight off invasive viruses called phages. And like any immune system – from single-celled to human – the first challenge of the bacterial immune system is to detect the difference between “foreign” and “self.” This is far from simple, as viruses, bacteria and all other living things…
