(PHILADELPHIA) - Over 90 percent of prostate cancers are detected at a curable stage, with men more likely to die of other diseases than from this cancer. Although patients with localized, low-risk prostate cancer have treatment options: active surveillance, also called watchful waiting, in which the cancer is monitored periodically to detect any changes, or active treatment with surgery and radiation. This choice is challenging, because medical science cannot reliably identify those men who are at risk for developing aggressive disease and may benefit from active treatment. Nonetheless, most men diagnosed with localized, low-risk prostate cancer choose active treatment.

A disabled African penguin at Mystic Aquarium in Mystic, Connecticut has gotten a new boot, thanks to 3-D printing and some middle school students.

Yellow/Purple (AKA “Purps”), a resident of Mystic Aquarium’s endangered African penguin colony,  was left with a nonfunctional flexor tendon in her ankle following a fight with another penguin. In an initial effort to immobilize, support and protect the site of injury, veterinarians at Mystic Aquarium fashioned a boot for Purps from moldable plastic material. While adequate, the animal care team at Mystic Aquarium knew there were more modern solutions available for the boot that would not only be more durable and less cumbersome for the small bird, but also would require less time than handcrafting a boot.

Johns Hopkins Bloomberg School of Public Health  graduate student Sara G. Rasmussen, from their Department of Environmental Health Sciences, says that people with asthma who live near bigger or larger numbers of active hydraulic fracturing (fracking) natural gas wells are 1.5 to four times likelier to have asthma attacks than those who live farther away.

Chimeric antigen receptor T cells (CAR T cells) are a promising immunotherapy approach to cancer treatment in which a patient's own immune cells attack tumors by targeting an identifying marker, or antigen, that is displayed at high levels on cancerous cells. However, CAR T cells that target a single antigen have had mixed results in clinical trials, which may be due to ongoing variability in the antigens that tumors display. In this month's issue of the JCI, a team led by Nabil Ahmed at Baylor College of Medicine demonstrated that CAR T cells that were engineered to target two different tumor antigens were more effective at controlling tumors in an animal model than typical CAR T cells, which target a single antigen.

The U.S. Centers for Disease Control and Prevention have recently become concerned about e-cigarette use yet scarcely mention that cigarette uptake has plummeted.

Cigarettes are the killer, not nicotine, but nicotine is what historically turned smoking into what the American Council on Science and Health (ACSH) deems a pediatric disease. Like caffeine, nicotine is addictive. If you smoked caffeine in a cigarette, it would be incredibly toxic whereas nicotine itself is relatively harmless. And because the CDC has overreacted to e-cigarettes, they become a cool rebellious thing for teems, just like cigarettes once were.

No need to head to the movie theater or download the video game app: Angry Birds can be found right in your backyard this summer--if you live in the suburbs, that is.

Virginia Tech researchers recently found that birds that live in suburban areas exhibit significantly higher levels of territorial aggression than their country counterparts. The results were recently published in Biology Letters.
