Coral reefs in Palau surprisingly resistant to naturally acidified waters
Ocean researchers working on the coral reefs of Palau in 2011 and 2012 made two unexpected discoveries that could provide insight into corals' resistance and resilience to ocean acidification, and aid in the creation of a plan to protect them. The team collected water samples at nine points along a transect that stretched from the open ocean, across the barrier reef, into the lagoon and then into the bays and inlets around the Rock Islands of Palau, in the western Pacific Ocean. With each...

Pancreas stem cell discovery may lead to new diabetes treatments
Stem cells in the adult pancreas have been identified that can be turned into insulin producing cells, a finding that means people with type 1 diabetes might one day be able to regenerate their own insulin-producing cells. The discovery was made by scientists from the Walter and Eliza Hall Institute and provides further evidence that stem cells don't only occur in the embryo. The ability to produce the hormone insulin is crucial for controlling blood sugar (glucose) levels. In people with...

Scientists discover an on-off switch for aging cells
Scientists at the Salk Institute have discovered an on-and-off "switch" in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age. In our bodies, newly divided cells constantly replenish lungs, skin, liver and other organs. However, most human cells cannot divide indefinitely–with each division, a cellular timekeeper at the ends of chromosomes shortens. When...

Logging means ants, worms and other invertebrates lose rainforest dominance
Invertebrates perform essential functions for the smooth running of the ecosystems in tropical forests. For example, creatures such as termites and millipedes help dead leaves decompose and release their nutrients back into the soil, and carnivorous ants and spiders act as predators of herbivorous invertebrates that would otherwise munch through all the foliage. Nearly a half of all tropical rainforests worldwide have been logged, and this often causes heavy changes to the number and type of...

In a role reversal, RNAs proofread themselves
Cold Spring Harbor, NY - Building a protein is a lot like a game of telephone: information is passed along from one messenger to another, creating the potential for errors every step of the way. There are separate, specialized enzymatic machines that proofread at each step, ensuring that the instructions encoded in our DNA are faithfully translated into proteins. Scientists at Cold Spring Harbor Laboratory (CSHL) have uncovered a new quality control mechanism along this path, but in a...

Scientists develop mesh that captures oil -- but lets water through
The unassuming piece of stainless steel mesh in a lab at The Ohio State University doesn't look like a very big deal, but it could make a big difference for future environmental cleanups. Water passes through the mesh but oil doesn't, thanks to a nearly invisible oil-repelling coating on its surface. In tests, researchers mixed water with oil and poured the mixture onto the mesh. The water filtered through the mesh to land in a beaker below. The oil collected on top of the mesh, and rolled...

New study shows parrotfish are critical to coral reef island building
As well as being a beautiful species capable of changing its colour, shape and even gender, new research published today shows that parrotfish, commonly found on healthy coral reefs, can also play a pivotal role in providing the sands necessary to build and maintain coral reef islands. The study, based on work in the Maldives and published in the journal Geology, found that parrotfish produced more than 85% of the new sand-grade sediment on the reefs around these reef islands. Reef islands...

Lab experiments question popular measure of ancient ocean temperatures
Understanding the planet's history is crucial if we are to predict its future. While some records are preserved in ice cores or tree rings, other records of the climate's ancient past are buried deep in the seafloor. An increasingly popular method to deduce historic sea surface temperatures uses sediment-entombed bodies of marine archaea, one of Earth's most ancient and resilient creatures, as a 150-million-year record of ocean temperatures. While other measures have gaps, this one is...

Odd histone helps suppress jumping genes in stem cells, study says
A family of proteins known as histones provides support and structure to DNA, but for years, scientists have been puzzling over occasional outliers among these histones, which appear to exist for specific, but often mysterious reasons. Now, researchers have uncovered a new purpose for one such histone variant: preventing genetic mutations by keeping certain so-called "jumping genes" in place. This research, which began at Rockefeller University and was published May 4 in Nature, reveals a...

Male hormones help lemur females rule
Lemur girls behave more like the guys, thanks to a little testosterone, according to a new study. Males rule in most of the animal world. But when it comes to conventional gender roles, lemurs -- distant primate cousins of ours -- buck the trend. It's not uncommon for lady lemurs to bite their mates, snatch a piece of fruit from their hands, whack them in the head or shove them out of prime sleeping spots. Females mark their territories with distinctive scents just as often as the males do....

Hybrid cells cause chaos around cancers
Rice University researchers have built a simulation to show how cancerous tumors manipulate blood-vessel growth for their own benefit. Like all cells, those in tumors need access to the body's fine network of blood vessels to bring them oxygen and carry away waste. Tumors have learned to game the process called angiogenesis in which new vessels sprout from existing ones, like branches from a tree. But some details have been hidden until now. The ability to stop tumors through...

Gene fuels age-related obesity and diabetes
Practically everyone gets fatter as they get older, but some people can blame their genes for the extra padding. Researchers have shown that two different mutations in a gene called ankyrin-B cause cells to suck up glucose faster than normal, fattening them up and eventually triggering the type of diabetes linked to obesity. The more severe of the two mutations, called R1788W, is carried by nearly one million Americans. The milder mutation, known as L1622I, is shared by seven percent of the...
