Starving cancer away | Sophia Lunt | TEDxMSU

Just like our healthy cells, malignant cancer cells need energy to survive. Dr. Sophia Lunt explains how she intends to cut off cancer cells’ survival potential, and pioneer a new way of halting their growth.

Dr. Sophia Lunt began her training in metabolism at Princeton University, where she received her Ph.D. studying the metabolic consequences of the antibiotic drug trimethoprim. As a postdoctoral fellow at MIT, she focused on cancer metabolism, and was awarded the CDMRP PRCRP Visionary Postdoctoral Fellowship from the Department of Defense to support her research. She currently runs a research lab focused on cancer metabolism at Michigan State University.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

Drones Sacrificed for Spectacular Volcano Video | National Geographic

Video technology and science converge on an active volcano in Vanuatu, where explorer Sam Cossman operated camera-mounted drones to capture high-definition images of the spectacular yet dangerous Marum Crater. Cossman and his team piloted the drones over the 7.5-mile-wide (12-kilometer) caldera while confronting toxic gases and boiling lava. Although two drones succumbed to the harsh environment, the team was able to bring back video and photos that will help scientists learn more about the volcano and the life around it.

Raising Cute Pandas: It’s Complicated | National Geographic

Giant panda cubs are adorable fluff balls that squeak and squeal. This endangered species is also incredibly tricky to breed and raise in captivity. In the 1960s, only 30 percent of infant pandas born at breeding centers survived. Today 90 percent survive. So, what changed?

In the last 20 years, China has successfully tackled three of the biggest problems holding the giant panda back. Through research and experimentation, researchers at China’s breeding centers have discovered how to encourage captive pandas to mate, how to make sure the pregnancy is successful, and how to keep the panda cubs alive once they’ve been born. For mating, they found that offering the females a choice of mate as well as enriching panda diets leads to a better chance of successful mating. A panda pregnancy can range from 73 days to 324 days depending on the weight of the mother panda and conditions she experiences during pregnancy. This knowledge, backed by medical advancements in artificial insemination, has allowed for more successful pregnancies in captive pandas.

Pandas often give birth to twins, and mothers usually choose to nurture only the stronger cub, resulting in the other twin’s death. Panda keepers have found a way to save this cub by “sharing custody.” Periodically, the keepers will swap out the infants, caring for one themselves while the other is with the mother. This way, every cub has a chance to survive. When in human care, the keepers must frequently massage the gut of the cub to help stimulate bowel movements—as infant pandas are unable to defecate without assistance.

All of these factors have led to the spike in the panda’s survival rates. More recently, the China Conservation and Research Center for the Giant Panda has made another breakthrough: It’s the only center in the world to successfully breed pandas and then release them into the wild. Five pandas have been released since 2006, though two have died. Before release, the pandas must go through a series of trials meant to test their abilities to survive in the wild, while avoiding human interference as much as possible. China’s dedication to panda research is leading the rest of the globe in panda conservation.

Why are these 32 symbols found in caves all over Europe | Genevieve von Petzinger

Written language, the hallmark of human civilization, didn’t just suddenly appear one day. Thousands of years before the first fully developed writing systems, our ancestors scrawled geometric signs across the walls of the caves they sheltered in. Paleoanthropologist and rock art researcher Genevieve von Petzinger has studied and codified these ancient markings in caves across Europe. The uniformity of her findings suggest that graphic communication, and the ability to preserve and transmit messages beyond a single moment in time, may be much older than we think.
