CRISPR gene editing possible without using a virus, scientists say

July 12 (UPI) -- Scientists have figured out a way to use genetically reprogram human immune cells without using viruses to insert DNA, as the CRISPR method of gene editing has traditionally required. In a study published recently in Nature, researchers at the University of California San Francisco show a new CRISPR technique involving T cells could help develop new and safer treatments for cancer, autoimmunity and rare inherited disorders. "This is a rapid, flexible method that can be used to alter, enhance, and reprogram T cells so we can give them the specificity we want to destroy cancer, recognize infections, or tamp down the excessive immune response seen in autoimmune disease," senior author Dr. Alex Marson, associate professor of microbiology and immunology, said in a press relea...

Why you should start paying off your student loans as soon as possible, even before graduation

Finance

When Ruth B., now 26, graduated from college in May 2014, she already had a few months of student loan payments under her belt. Ruth, who asked that her last name not be used, had taken out federal loans to help cover her tuition and living expenses every year. But in her senior year her family finances changed when her younger brother started college, as well. "My senior year I couldn't count on my mom to help me out, so I took out a private loan from Sallie Mae to cover everything that financial aid wouldn't cover," Ruth said. Ruth realized right...

ESA's Mars Express finds possible supervolcano remnant

Science

April 13 (UPI) -- ESA's Mars Express has photographed a unique and mysterious geologic structure on the Martian surface.Astronomers aren't sure of the crater's origins. The crater, dubbed Ismenia Patera, may have been created by a meteorite impact. It's also possible the imprint was left behind by an ancient supervolcano.The layout and structural patterns seen in and around Ismenia Patera are different and more complex than the typical impact crater. Uneven lumps of rock are found scattered around the outer edge of the crater.Scientists believe the rocky deposits are debris ejected by neighboring impacts. These miniature impacts have created their own system of gullies inside Ismenia Patera.The crater's floor is dynamic, too, showing signs of movement. The floor is likely composed of a roc...

Is It Possible to Eat Too Much Fruit?

Health

You've been told since you were a kid how important it is to eat fruit. But is there such thing as too much? As a nutritionist, I've worked with clients on both ends of the fruit-eating spectrum: Some shunned fruit completely due to its carb and sugar content, while others loaded up on fruit because it's rich in nutrients. The reality is, the ideal amount lies somewhere in between these two extremes, and it varies from person to person. To help you figure out your own sweet spot when it comes to fruit, here are four important things to keep in mind.Stick with two to four servingsAs a general rule, you probably need somewhere between two to four servings of fruit a day. What's a proper serving? Either one cup, or a piece of fruit about the size of a baseball. But if your activity level vari...
