MedicineA team of German and American scientists recently announced a organ transplant breakthrough. The researchers were able to keep a pig heart beating inside a baboon for more than two years, using genetic engineering and immunosuppression drugs to keep the baboon from rejecting the pig heart.

PsychologyBabies as young as 12 months will take a smaller offering from a Good Samaritan than a larger one from a wrongdoer. However, children are much more willing to “do business” with the bad guy when their offer is substantially higher than the do-gooder’s, a new study shows. (news.yale.edu)

PhysicsTwo bodies at different temperatures in vacuum constantly exchange heat. Researchers have devised a formula that describes the maximum heat transfer in such scenarios. Surprisingly the formula suggests that a million times more heat transfer is possible between close objects than previously thought. (phys.org)

NeuroscienceBabies raised in bilingual households show brain activity associated with executive functioning as early as 11 months, new research demonstrates. The study gives evidence that the brains of babies from bilingual families remain more open to learning new language sounds. (sciencedaily.com)

CancerAged tumor cells in melanoma behave differently than younger tumor cells. Changes in the microenvironment make these older tumor cells more metastatic and resistant to treatment. Scientists demonstrated how antioxidants could serve as a better treatment strategy for older patients with melanoma. (medicalxpress.com)

NanoscienceScientists have discovered that graphene can filter out radiation in much the same way as polarized glasses. Using their research, they have developed a microchip using graphene that could help wireless telecommunications share data at a rate that is ten times faster than currently possible. (phys.org)

CancerResearchers report that breast cancer cells need to take up lipids from the extracellular environment in order to continue proliferating. The main protein involved in this process is LIPG, an enzyme found in the cell membrane and without which tumour cell growth is arrested (eurekalert.org)

MedicinePig hearts may save human lives. One day cardiac patients may enjoy a new lease of life with pig hearts, said researchers reporting a major advance in cross-species transplantation. Due to the shortage of organ donors, the use of animal organs in humans has long been a holy grail of medical science. (medicalxpress.com)

PhysicsScientists have made a significant advance toward making movies of extremely fast atomic processes. Using a superfast, “electron camera,” researchers have captured the world’s fastest UED images of nitrogen molecules rotating in a gas, with a record shutter speed of 100 quadrillionths of a second.
