During the summer of 1997-1998, measurements of beam absorption and beam attenuation coefficients, and downwelling and upwelling irradiance were made in the Southern Ocean along a S-N transect at 6 de...
Earth Sciences |Scientists at the California Institute of Technology (Caltech) have uncovered the physical mechanism by which arrays of nanoscale (billionths-of-a-meter) pillars can be grown on polymer films with ver...
Physics and Astronomy |By examining data from a 20-year-old clinical trial, a research team based at the MassGeneral Institute for Neurodegenerative Diseases (MGH-MIND) and Harvard School of Public Health (HSPH), has found ...
Health and Medicine |For over a century, the eye has been considered to lack lymphatics, a circulation responsible for pumping fluid and waste out of tissues. The inability to clear that fluid from the eye is linked to gl...
Health and Medicine |Cell size is regulated by the balance of positively and negatively charged ions and other solutes in the fluid inside and outside cells, which in turn prevents water from moving across cell membranes ...

Earth Sciences |The masterpieces that spring from the talents of Rembrandt, Van Gogh and other artists often begin with the creation of a gradient of colors on a palette.In a similar manner, researchers at th...
Life Sciences |“When started above the surface, the animals dive into the sand within a half second. Once below the surface, they no longer use their limbs for propulsion -- instead, they move forward by propagating...
Studies and Analyses |These "beneficial" immune cells display a propensity to migrate from the blood into inflamed nervous tissue. "Drawn in by specific chemoattractants, they obviously counteract the detrim...
Life Sciences |Researchers at the University of Oklahoma Health Sciences Center have found a way to use a natural compound to stop one of the leading causes of blindness in the United States. The research appears on...
Health and Medicine |One of the major challenges in emergency medicine is the early diagnosis of Acute Myocardial Infarction (AMI) in patients presenting with chest pain or other symptoms suggestive of this disease. Until...
Life Sciences |Once the baby arrives, many new mothers want to return to their former weight quickly – just like film stars who appear in the media in bikinis just weeks after giving birth. But according to ...
Health and Medicine |If they are right, drugs already under study to boost PPAR signaling in adults with lung injuries, may help these infants restore a healthy balance of blood vessel dilation and contraction, preventing...
Health and Medicine |An extreme heat wave affected much of the state of California during mid- to late July 2006, breaking daily maximum temperature records in many regions of the State. A study conducted by resea...
Studies and Analyses |An immune response ultimately is needed to eliminate the virus, but this research suggests that it’s not the presence of the virus alone that does all the harm to a sick person. Instead, the fluid bui...
