Are my muscular dystrophy drugs working?
People with muscular dystrophy could one day assess the effectiveness of their medication with the help of a smartphone-linked device, a new study in mice suggests. The study used a new method to process ultrasound imaging information that could lead to hand-held instruments that provide fast, convenient medical information.

Scientists replicate the tide with two buckets, aquarium tubing, and a pump
A design for a new, inexpensive tidal simulation unit enables researchers to investigate tidal marsh plant growth in a controlled setting. The unit costs less than US$27 to build, takes up less than two square feet of space, and does not require external plumbing; the protocol is available in the November issue of Applications in Plant Sciences. The system could be an important tool for researchers working to preserve and restore environmentally important wetlands.

Goodbye to rainy days for US, Japan's first rain radar in space
After 17 years of groundbreaking 3-D images of rain and storms, the joint NASA and Japan Aerospace Exploration Agency Tropical Rainfall Measuring Mission will come to an end next year. NASA predicts that science operations will cease in or about April 2015, based on the most recent analysis by mission operations at NASA's Goddard Space Flight Center, Greenbelt, Maryland.

Tracking a gigantic sunspot across the Sun
An active region on the sun -- an area of intense and complex magnetic fields -- rotated into view on Oct. 18, 2014. Labeled AR 12192, it soon grew into the largest such region in 24 years, and fired off 10 sizable solar flares as it traversed across the face of the sun. The region was so large it could be seen without a telescope for those looking at the sun with eclipse glasses, as many did during a partial eclipse of the sun on Oct. 23.

Massive geographic change may have triggered explosion of animal life
A new paper by The University of Texas at Austin's Jackson School of Geosciences published in the November issue of Geology suggests a major tectonic event may be connected with the apparent burst of life that occurred 530 million years ago during the Cambrian explosion.

Mussels on California Coast contaminated with giardia transmitted from land-based sources
The pathogen Giardia duodenalis is present in mussels from freshwater run-off sites and from areas where California Sea Lions lounge along the coast of California, according to a team of researchers from the University of California, Davis. One of the G. duodenalis strains found is known to infect humans; the two others occur mostly in dogs and other canids. 'Thus, the detection of these assemblages implies a potential public health risk if consuming fecally contaminated water or uncooked shellfish,' says coauthor Woutrina Smith.

Immune cells proposed as HIV hideout don't last in primate model
New research from Yerkes National Primate Research Center, Emory University, sheds light on the question of which cells support viral replication and persistence, and the answers have implications for future efforts to eliminate HIV from the body in human patients.

Breaking down DNA by genome
A new study in the November issue of Applications in Plant Sciences provides plant biologists with an efficient approach for separating plant nuclear DNA from organellar DNA for genomic and metagenomic studies. The approach targets the methyl-CpG-binding domain and allows researchers to isolate nuclear, chloroplast, and mitochondrial DNA, and can also target genomes of endophytes and prokaryotic parasites in plant DNA samples.

Fun and games make for better learners
Four minutes of physical activity can improve behavior in the classroom for primary school students, according to new research by Brendon Gurd. A brief, high-intensity interval exercise, or a 'FUNterval,' for Grade 2 and Grade 4 students reduced off-task behaviors like fidgeting or inattentiveness in the classroom.

Scientists seek cure for devastating witches' broom disease of the chocolate tree
As children across the country savor the last of this year's Halloween candy, a deadly and untreatable fungus, Moniliophthora perniciosa, is hexing chocolate tree, Theobroma cacao, plantations in many South and Central American countries, threatening livelihoods and imperiling the world's favorite treat. A team of scientists from Brazil has taken the first steps towards conquering this aggressive fungus by deciphering the interaction between the fungus and the chocolate tree at the molecular level.

Is fleet diversity key to sustainable fisheries?
Concern about fisheries is widespread around the world. Over the past several decades, a robust discussion has taken place concerning how to manage fisheries better to benefit ecosystems and humans. Much of the discussion has focused on preserving biological diversity, a critical component of healthy ecosystems. One aspect that gets less attention is the role of fishing fleet diversity.

Cell division, minus the cells
Researchers have reconstituted cell division -- complete with signals that direct molecular traffic -- without the cell. Combining frog-egg extracts with lipid membranes that mimic the membrane of the cell, they built a cell-free system that recapitulates how the cleavage furrow is assembled.

Decoding the emergence of metastatic cancer stem cells
In the first study of its kind, Rice University researchers have mapped how information flows through the genetic circuits that cause cancer cells to become metastatic. The research reveals a common pattern in the decision-making that allows cancer cells to both migrate and form new tumors.

Improved mouse model will accelerate research on potential Ebola vaccines, treatments
Researchers at the University of North Carolina at Chapel Hill and colleagues have developed the first genetic strain of mice that can be infected with Ebola and display symptoms similar to those that humans experience. This work, published in the current issue of Science, will significantly improve basic research on Ebola treatments and vaccines, which are desperately needed to curb the worldwide public health and economic toll of the disease.

Green spaces don't ensure biodiversity in urban areas
Green spaces in cities are great, but they don't ensure biodiversity, according to University of Iowa biologists. The team found insect abundance was lacking in two common urban trees, suggesting insect movement may be limited by barriers, such as roads and buildings. Results appear in the journal PLOS ONE.

NASA sees remnants of Nilofar go to cyclone graveyard
Wind shear has caused the demise of former Tropical Cyclone Nilofar in the northern Arabian Sea. NASA's Aqua satellite passed over Nilofar on Oct. 31 and captured an image that shows strong wind shear has pushed the bulk of clouds and showers away from Nilofar's center, basically sending the storm to its grave.

Lack of oxygen delayed the rise of animals on Earth
Scientists have long speculated as to why animal species didn't flourish sooner, once sufficient oxygen covered the Earth's surface. Animals began to prosper at the end of the Proterozoic period -- but what about the billion-year stretch before that, when most researchers think there also was plenty of oxygen? Yale University researcher Noah Planavsky and his colleagues found that oxygen levels during the 'boring billion' period were only 0.1 percent of what they are today.

Bladderwrack: Tougher than suspected
The bladderwrack Fucus vesiculosus is actually one of the most important species of brown algae along the North Atlantic coasts. But for years their populations in the Baltic Sea were declining. Looking for the reasons, biologists of GEOMAR Helmholtz Centre for Ocean Research Kiel now have analyzed the defense mechanisms of bladderwrack against bacterial vermins under different environmental conditions. The surprising result: The defense proved to be very robust to environmental changes. The study is published today in the international online-journal PLOS ONE.

Nearly one out of four older Americans say that either they or a family member have experienced excessive or unwanted medical treatment, according to the latest issue of The Gerontological Society of America's Public Policy & Aging Report, which goes on to show that Americans strongly support holding doctors accountable when they fail to honor patients' end-of-life health care wishes.
