November 1, 2019 – Scientists have shown how measles causes long-term damage to the immune system, leaving people vulnerable to other infections. Researchers from the Wellcome Sanger Institute, University of Amsterdam and their collaborators revealed that the measles virus deletes part of the immune system’s memory, removing previously existing immunity to other infections, in both […]

October 29, 2019 – By combining models of magnitude 9 to 9.2 earthquakes on the Cascadia Subduction Zone with geological evidence of past coastal changes, researchers have a better idea of what kind of megathrust seismic activity was behind the 1700 Cascadia earthquake. The analysis by Erin Wirth and Arthur Frankel of the U.S. Geological […]

October 23, 2019 – Major landslides triggered by the 1964 magnitude 9.2 Great Alaska earthquake responded to, but were not reactivated by, the magnitude 7.1 Anchorage earthquake that took place 30 November 2018, researchers concluded in a new study published in Seismological Research Letters. The shaking that accompanied the 2018 earthquake was of a higher […]

October 22, 2019 – With the growth of home DNA testing, online services such as GEDMatch, MyHeritage and FamilyTreeDNA have become popular places for people to upload their genetic information, research their genealogy and find lost relatives. They have also been used by law enforcement to find criminal suspects through a DNA match with relatives. […]

October 3, 2019 – A test to detect opioid drugs in exhaled breath has been developed by engineers and physicians at the University of California, Davis. A breath test could be useful in caring for chronic pain patients as well as for checking for illegal drug use. “There are a few ways we think this could […]

September 26, 2019 – This new visualization of a black hole illustrates how its gravity distorts our view, warping its surroundings as if seen in a carnival mirror. The visualization simulates the appearance of a black hole where infalling matter has collected into a thin, hot structure called an accretion disk. The black hole’s extreme […]

LONDON, September 20, 2019 − Leading scientists have declared their support for the global climate strike which starts today. In a statement published by the Earth League, headed Humanity is Tipping the Scales of the World, 20 respected scientists throw their weight into the argument. Among a stellar company, they number Lord Nicholas Stern, Johan […]

WASHINGTON, Sept. 16, 2019 —Valley fever is endemic to hot and dry regions like the southwestern United States and California’s San Joaquin Valley, but a new study predicts climate change will cause the fungal infection’s range to more than double in size this century, reaching previously unaffected areas across the western U.S. In a new […]

CATONSVILLE, MD, September 13, 2019 –There are more than 60 million business pages on Facebook and that number is from 2017. With those pages come scores of positive and negative posts generated by Facebook users. What researchers have seen is companies have very little control over what customers post, and negative posts can severely damage brands. […]

Sept. 16, 2019 – Despite its proven success at preventing cancer, many adolescents are still not getting the HPV vaccine. A new study from the University of Colorado School of Medicine at the Anschutz Medical Campus shows that physicians’ delivery and communication practices must improve to boost vaccination completion rates. Health care providers must also […]

September 16, 2019 – Domestic cats, like many other mammals, use smelly secretions from anal sacs to mark territory and communicate with other animals. A new study from the Genome Center at the University of California, Davis, shows that many odiferous compounds from a male cat are actually made not by the cat, but by […]
