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 [...]

Trees Save Lives, Reduce Respiratory Problems

While trees' pollution removal equated to an average air quality improvement of less than 1 percent, the impacts of that improvement are substantial. Researchers valued the human health effects of the reduced air pollution at nearly $7 billion every year.

In the first broad-scale estimate of air pollution removal by trees nationwide, US Forest Service scientists and collaborators calculated that trees are saving more than 850 human lives a year and preventing 670,000 incidents of acute respiratory symptoms. While trees’ pollution removal equated to an average air quality improvement of less than 1%, the impacts [...]

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 [...]

Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug, says a new study by Tulane University School of Medicine cancer researchers. The study, “Circadian and Melatonin Disruption by Exposure to Light at Night Drives Intrinsic Resistance to [...]

Newly Discovered Gut Virus Lives In Half The World’s Population

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 [...]
