Function of mysterious RNAs may often lie in their genes
Scientists from Penn Medicine and other institutions unlock a mystery about 'long non-coding RNAs'. A new genetic clue discovered by a team co-led by a researcher at the Perelman School of Medicine at the University of Pennsylvania is shedding light on the functions of the mysterious "long non-coding RNAs" (lncRNAs). These molecules are transcribed from genes and are often abundant in cells, yet they do not code for proteins. Their functions have been almost entirely unknown--and in recent...

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...

One of the last strongholds for Western chimpanzees
When Liberia enters the news it is usually in the context of civil war, economic crisis, poverty or a disease outbreak such as the recent emergence of Ebola in West Africa. Liberia's status as a biodiversity hotspot and the fact that it is home to some of the last viable and threatened wildlife populations in West Africa has received little media attention in the past. This is partly because the many years of violent conflict in Liberia, from 1989 to 1997 and from 2002 to 2003, thwarted efforts...

Scientists reconstruct ancient impact that dwarfs dinosaur-extinction blast
Picture this: A massive asteroid almost as wide as Rhode Island and about three to five times larger than the rock thought to have wiped out the dinosaurs slams into Earth. The collision punches a crater into the planet's crust that's nearly 500 kilometers (about 300 miles) across: greater than the distance from Washington, D.C. to New York City, and up to two and a half times larger in diameter than the hole formed by the dinosaur-killing asteroid. Seismic waves bigger than any recorded...

Firefly protein enables visualization of roots in soil
Plants form a vast network of below-ground roots that search soil for needed resources. The structure and function of this root network can be highly adapted to particular environments such as desert soils where plants like Mesquite develop tap roots capable of digging 50 meters deep to capture precious water resources. Excavation of root systems reveals these kinds of adaptations but is laborious, time consuming, and does not provide information on how growing roots behave. A new imaging tool...

Signs of deforestation in Brazil
Multiple fires are visible in in this image of the Para and Mato Grosso states of Brazil. Many of these were most likely intentionally set in order to deforest the land. Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a nonforest use. Examples of deforestation include conversion of forestland to farms, ranches, or urban use. The herringbone-patterned tan lines cutting through the dark green of the Amazon Rainforest in the middle of the image...

Ascaris lumbricoides
Ascaris lumbricoides is otherwise known as the large intestinal roundworm of humans. It looks a lot like a large earthworm, but the two are not related. The earthworm is an annelid; it lives in the soil, feeding on organic debris. A. lumbricoides is a parasitic nematode, or roundworm; adults are found only in the intestines of humans, feeding on intestinal contents as they flow past. If you were to compare the two very carefully, you would note that the earthworm has little tufts of bristles...

Brain's on-off thirst switch identified
NEW YORK, NY (January 26, 2015)--Neurons that trigger our sense of thirst--and neurons that turn it off--have been identified by Columbia University Medical Center neuroscientists. The paper was published today in the online edition of Nature. For years, researchers have suspected that thirst is regulated by neurons in the subfornical organ (SFO), in the hypothalamus. But it has been difficult to pinpoint exactly which neurons are involved. "When researchers used electrical current to...

New Science paper calculates magnitude of plastic waste going into the ocean
A plastic grocery bag cartwheels down the beach until a gust of wind spins it into the ocean. In 192 coastal countries, this scenario plays out over and over again as discarded beverage bottles, food wrappers, toys and other bits of plastic make their way from estuaries, seashores and uncontrolled landfills to settle in the world's seas. How much mismanaged plastic waste is making its way from land to ocean has been a decades-long guessing game. Now, the University of Georgia's Jenna Jambeck...

Damaged DNA may stall patrolling molecule to initiate repair
Sites where DNA is damaged may cause a molecule that slides along the DNA strand to scan for damage to slow on its patrol, delaying it long enough to recognize and initiate repair. The finding suggests that the delay itself may be the key that allows the protein molecule to find its target, according to researchers at the University of Illinois at Chicago. Usually, the repair protein zips along quickly, says Anjum Ansari, UIC professor of physics and co-principal investigator on the study,...

Virginia Tech researchers take cue from spider glue in efforts to create new materials
A taut tug on the line signals the arrival of dinner, and the leggy spider dashes across the web to find a tasty squirming insect. The spider, known as an orb weaver, must perfectly execute this moment, from a lightning-fast reaction to an artfully spun web glistening with sticky glue. This glue -- created when glycoproteins are secreted from a spider's abdomen and interact with the atmosphere -- has been studied for the past 12 years by Brent Opell, a professor of biological sciences in the...
