The 31-year-old Moore Clinic operated by the Johns Hopkins AIDS Service at the School of Medicine is a historic operation — the second-oldest AIDS clinic in the country. But when Jason Farley, PhD, MPH, CRNP, looks nowadays at the makeup of Moore’s caregiving staff, he worries that he’s seeing too much history. “There are 12 [...]

Making Cancer Glow To Improve Surgical Outcomes

The best way to cure most cases of cancer is to surgically remove the tumor. The Achilles heel of this approach, however, is that the surgeon may fail to extract the entire tumor, leading to a local recurrence. With a new technique, researchers at the University of Pennsylvania have established a new strategy to help [...]

Potential ‘Universal’ Blood Test For Cancer Discovered

The Lymphocyte Genome Sensitivity (LGS) test looks at white blood cells and measures the damage caused to their DNA when subjected to different intensities of ultraviolet light (UVA), which is known to damage DNA. The results of the empirical study show a clear distinction between the damage to the white blood cells from patients with cancer, with pre-cancerous conditions and from healthy patients.

Researchers from the University of Bradford have devised a simple blood test that can be used to diagnose whether people have cancer or not. The test will enable doctors to rule out cancer in patients presenting with certain symptoms, saving time and preventing costly and unnecessary invasive procedures such as colonoscopies and biopsies being carried [...]

New Device Detects Deadly Lung Disease

A scientist from the University of Exeter has developed a simple, cheap and highly accurate device for diagnosing a frequently fatal lung disease which attacks immune deficient individuals such as cancer patients and bone marrow transplant recipients. The lateral-flow device (LFD), created by Professor Chris Thornton, detects invasive pulmonary aspergillosis, a notoriously difficult to diagnose [...]

Odds are, there’s a virus living inside your gut that has gone undetected by scientists for decades. A new study led by researchers at San Diego State University has found that more than half the world’s population is host to a newly described virus, named crAssphage, which infects one of the most common types of [...]
