MIT study illuminates thoughts and memories

Researchers at MIT's Picower Institute for Learning and Memory have found that rats use a mental instant replay of their actions to help them decide what to do next, shedding new light on how animals and humans learn and remember.

On a warm June day at the Martin Luther King, Jr. Academic Middle School in San Francisco, the science classroom buzzes with activity. Students wearing goggles and white lab coats carefully cut open preserved lamb hearts, probing the cavities with gloved fingers. They “ooh” and “ah” when they see that the walls of the left ventricle are thicker than the right. They find the heartstrings – the tendons that connect the valves to the heart muscle. They use scientific terms: “Mine’s necrotic!” declares one student.

Scientists from Stanford University have teamed up with Israeli and Jordanian researchers to protect the Gulf of Aqaba, a strategic waterway whose fragile marine ecosystem is vital to both Israel and Jordan. Participants in the NATO-funded project say they are bridging the Arab-Israeli political divide for the sake of science, peace and environmental conservation.

best in science, biology, stem cells— By Charlie Feigenoff

Fat may carry negative connotations in today's world, but the stem cells found in fat tissue may prove valuable for their potential to heal wounds.

As Shayn Peirce-Cottler, an assistant professor of biomedical engineering at the University of Virginia, describes them, they are hard-working and tough. Although these adult stem cells lack the infinite plasticity of embryonic stem cells, they can be used for therapeutic purposes without raising the ethical issues that have made stem cell research so controversial. And, as Peirce-Cottler has found in the course of a series of collaborations with Dr. Adam Katz, an associate professor of plastic surgery, their healing powers are considerable.

LA JOLLA, Calif., – Scientists at Burnham Institute for Medical Research (Burnham) have found that the Caspase-8 protein, long known to play a major role in promoting programmed cell death (apoptosis), helps relay signals that can cause cancer cells to proliferate, migrate and invade surrounding tissues. The study was published in the journal Cancer Research on June 15.
