In pulmonary arterial hypertension (PAH), high blood pressure in the lungs' arteries causes the heart to work extra hard to pump blood to the lungs and around the rest of the body. The condition is rare but deadly, and current treatments are expensive and have side effects and inconvenient modes of delivery. There is no cure.
PULLMAN, Wash. - Wildlife need to move to survive: to find food, reproduce and escape wildfires and other hazards. Yet as soon as they leave protected areas like national forests or parks, they often wind up on a landscape that is very fragmented in terms of natural boundaries and human ones.
Berkeley Lab Helps Reveal How Dinosaur Blood Vessels Can Preserve Through the Ages
-- By Aliyah Kovner
A team of scientists led by Elizabeth Boatman at the University of Wisconsin Stout used X-ray imaging and spectromicroscopy performed at Berkeley Lab's Advanced Light Source (ALS) to demonstrate how soft tissue structures may be preserved in dinosaur bones - countering the long-standing scientific dogma that protein-based body parts cannot survive more than 1 million years.
The low-pressure area that had once been Tropical Cyclone Francisco has been lingering in the Southern Indian Ocean since Feb. 6 when it weakened below tropical cyclone status. Since then, Francisco's remnants moved into an area of warm waters and low wind shear allowing the low-pressure area to re-organize, consolidate and re-form. NASA's Aqua satellite provided forecasters with a visible image of the zombie storm.
Hydropower dams, which use flowing water to turn a series of turbines to generate electricity, provide a source of energy that doesn't rely on fossil fuels. But they also disrupt the flow of rivers, and impact the fish and people that live there.
Scientists have been monitoring many environmental effects of dams, including how they affect a river's temperature -- and could potentially threaten the fish downstream.
The paradox of Schrödinger's cat - the feline that is, famously, both alive and dead until its box is opened - is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seems to predict that macroscopic objects (like cats) can, sometimes, exist simultaneously in more than one completely distinct state. Many physicists have tried to solve this paradox over the years, but no approach has been universally accepted.
Researchers of the Hubrecht Institute (KNAW - The Netherlands) and the Max Planck Institute in Münster (Germany) have revealed how an essential protein helps to activate genomic DNA during the conversion of regular adult human cells into stem cells. Their findings are published in the Biophysical Journal.
Copper has been essential to human technology since its early days--it was even used to make tools and weapons in ancient times. It is widely used even today, especially in electronic devices that require wiring. But, a challenge with using copper is that its surface oxidizes over time, even under ambient conditions, ultimately leading to its corrosion. And thus, finding a long-term method to protect the exposed surfaces of copper is a valuable goal. One common way of protecting metal surfaces is by coating them with anti-corrosive substances.
Under JST's Strategic Basic Research Programs, Noda Nobuo (Laboratory Head) and Fujioka Yuko (Senior Researcher) of the Institute of Microbial Chemistry, in collaboration with other researchers, discovered that a liquid-like condensate (liquid droplets(1)) in which the Atg protein is clustered through the liquid-liquid phase separation(2) is the structure responsible for the progression of autophagy.
Standard comfort measurements used to design buildings' heating and cooling systems share a common flaw, according to new research. The researchers said the findings could mean that designers have relied on inaccurate measurements for decades when building their systems.
A new innovation makes it possible, for the first time, to quantitatively assess children's spontaneous movement in the natural environment.
Researchers have developed a smart jumpsuit, or a garment that accurately measures the spontaneous and voluntary movement of infants from the age of five months. Details on their motility help in assessing abnormal neurological development, among other things.

Since 1998, scientists have documented the global loss of amphibians. More than 500 amphibian species have declined in numbers, including 90 that have gone extinct, due to the fungal pathogen Batrachochytrium, commonly known as chytrid.
A French-British team directed by the Laboratoire d'océanographie de Villefranche-sur-Mer (CNRS/Sorbonne Université) has just discovered that a little known process regulates the capacity of oceans to sequester carbon dioxide (CO2). It should be noted that photosynthesis performed by phytoplankton on the ocean's surface transforms atmospheric CO2 into organic particles, some of which later sink to its depths. This essential mechanism sequesters part of oceanic carbon. However, approximately 70% of this particle flux is reduced between a depth of 100 and 1,000 metres.
Juul, the popular e-cigarette brand that is being sued for fueling the youth e-cigarette epidemic, may have influenced high school students' perception of vaping such that some Juul users do not consider themselves e-cigarette users, a Rutgers-led study finds.
