...teaching or research. Additionally, pharma contributed more than $11.5 million to the school last year for research and continuing-education classes. The Times covered these details in its stories and included the damning fact that during the November demonstration, a Pfizer employee was on campus photographing protesters with a cell-phone camera. Pfizer did not deny the account but contended that the employee did nothing wrong. (See the top 10 scandals...
...group of researchers at Massachusetts General Hospital’s Institute for Neurodegenerative Disease (MIND) have discovered that the plaques associated with Alzheimer’s disease may affect a type of nervous system cell called an astrocyte, providing new insight into the far-reaching effects of the disease as well as possible therapeutic targets. Astrocytes are star-shaped cells that make up almost half the volume of the brain, and were traditionally thought to be support cells. It is now known that they can transmit signals through transient increases in calcium levels. “Astrocytes are often thought...
...provides a biological explanation for recent clinical studies that have shown a negative correlation between caffeine intake and the risk of developing non-melanoma skin cancer. According to the study, caffeine appears to reduce the risk of some skin cancers by interrupting the ATR pathway, causing apoptosis or cell suicide of these damaged and potentially cancerous cells. ATR is a protein kinase that is responsible for facilitating the replication of DNA, especially in damaged and dividing cells. While ATR plays a minimal role in normal cells, recently damaged and precancerous cells need the function of ATR, Nghiem explained. The researchers...
...Molecular and Cellular Biology professor who asked that he not be named to protect his relationship with the University. “But now, unfortunately, since we cannot grow, the situation involves making choices.”The delay has compelled the University to plan to relocate stem cell researchers originally bound for Allston to a Cambridge facility currently occupied by faculty members in the MCB department—a move that has triggered backlash from professors who object to the administration’s apparent prioritization of stem cell research at the expense of their own discipline...
Unfortunately it's too late to legislate that no one should be allowed a cell phone until he or she is at least 18 and fully licensed to use it. Every parent understands that handing over the car keys marks a fateful passage, so much more freedom and possibility, so much more risk and temptation. But cell phones took us by surprise: so small, so innocent, so powerful in the hands of a bored or twisted teen who now has an extremely efficient tool for wasting time, cheating on tests, organizing fights, bullying classmates, phoning in bomb threats, arranging drug...
