| Dual role of carbon dioxide in photosynthesis: Pioneering findings Posted: 13 Apr 2014 12:40 PM PDT Carbon dioxide, in its ionic form bicarbonate, has a regulating function in the splitting of water in photosynthesis, researchers have found. This means that carbon dioxide has an additional role to being reduced to sugar. The pioneering work opens up a new research field where researchers can investigate possible biological and ecological consequences of the dual role of carbon dioxide. |
| Finding the switch: Researchers create roadmap for gene expression Posted: 13 Apr 2014 11:00 AM PDT In a new study, researchers have taken the first steps toward creating a roadmap that may help scientists narrow down the genetic cause of numerous diseases. Their work also sheds new light on how heredity and environment can affect gene expression. Pinpointing the genetic causes of common diseases is not easy, as multiple genes may be involved with a disease. Moreover, disease-causing variants in DNA often do not act directly, but by activating nearby genes. |
| Hereditary trauma: Inheritance of traumas and how they may be mediated Posted: 13 Apr 2014 10:59 AM PDT Extreme and traumatic events can change a person -- and often, years later, even affect their children. Researchers have now unmasked a piece in the puzzle of how the inheritance of traumas may be mediated. The phenomenon has long been known in psychology: traumatic experiences can induce behavioural disorders that are passed down from one generation to the next. It is only recently that scientists have begun to understand the physiological processes underlying hereditary trauma |
| Sharks contain more pollutants than polar bears Posted: 11 Apr 2014 06:14 AM PDT The polar bear is known for having alarmingly high concentrations of PCB and other pollutants. But researchers have discovered that Greenland sharks store even more of these contaminants in their bodies. Greenland sharks live in deep water, at depths of 200 to 600 meters, and live farther north than any other shark. It is also long lived, and can live to be 100 years old. They are also known as the grey shark or gurry shark. |
