Potential New Flu Drugs Target Immune Response, Not Virus

July 22, 2014 2:59 pm | News | Comments

The seriousness of disease often results from the strength of immune response, rather than with the virus, itself. Turning down that response, rather than attacking the virus, might be a better way to reduce that severity. Researchers have taken the first step in doing that for the H7N9 influenza, and their work has led to identification of six potential therapeutics for this highly virulent strain.

Viral Therapy Could Boost Limb-saving Cancer Treatment

July 22, 2014 2:52 pm | News | Comments

Viruses designed to target and kill cancer cells could boost the effectiveness of chemotherapy to the arms and legs and help avoid amputation. Scientists tested the effectiveness of a genetically engineered version of the virus used to vaccinate against smallpox. They found use of the virus alongside isolated limb perfusion chemotherapy was more effective in rats than either treatment on its own.

Brain Waves Show Learning to Read Doesn’t End in Fourth Grade

July 22, 2014 2:43 pm | News | Comments

Teachers-in-training have long been taught that the fourth grade is when students stop learning to read and start reading to learn. But a new study tested the theory by analyzing brain waves and found that fourth-graders do not experience a change in automatic word processing. Instead, some types of word processing become automatic before fourth grade, while others don’t switch until after fifth.

Bacteria Swim with Bodies and Flagella

July 22, 2014 2:34 pm | News | Comments

Many bacteria swim using flagella, corkscrew-like appendages that push or pull bacterial cells like propellers. It had been assumed that the flagella do all the work during swimming, while the rest of the cell body is just along for the ride. But new research shows that in at least one species, the cell body is actively carving out a helical trajectory through the water that produces thrust and contributes to the organism's ability to swim.

Stem Cells Aid Muscle Repair and Strengthening After Resistance Exercise

July 22, 2014 2:10 pm | News | Comments

A new study in mice reveals that mesenchymal stem cells (MSCs) help rejuvenate skeletal muscle after resistance exercise. By injecting MSCs into mouse leg muscles prior to several bouts of eccentric exercise, researchers were able to increase the rate of repair and enhance the growth and strength of those muscles in the exercising mice.

Researchers Successfully Eliminate the HIV Virus from Cultured Human Cells

July 22, 2014 1:49 pm | Videos | Comments

The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of Temple University School of Medicine researchers has designed a way to snip out the integrated HIV-1 genes for good.

Mixed Genes Mix Up the Migrations of Hybrid Birds

July 22, 2014 1:23 pm | News | Comments

Mixed genes appear to drive hybrid birds to select more difficult routes than their parent species, according to new research from University of British Columbia zoologists. the researchers harnessed a flock of B.C. Swainson’s thrushes with tiny geolocating backpacks to map their routes as they migrated south through the U.S. to Central and South America.
