A newly developed assay may help investigators identify novel drug candidates to protect kidney cells and prevent or treat chronic kidney disease (CKD).

Science needs to catch up with the public awareness, say researchers.
The organic chemicals in fracking fluid have been uncovered in two new studies, providing a basis for water contamination testing and future regulation. The research, published in Trends in Environmental Analytical Chemistry and Science of the Total Environment, reveals that fracking fluid contains compounds like biocides, which are potentially harmful if they leak into the groundwater.
Light is an extremely useful tool for quantum communication, but it has one major disadvantage: it usually travels at the speed of light and cannot be kept in place. A team of scientists at the Vienna University of Technology has now demonstrated that this problem can be solved - not only in strange, unusual quantum systems, but in the glass fiber networks we are already using today.
Researchers are always searching for improved technologies, but the most efficient computer possible already exists. It can learn and adapt without needing to be programmed or updated. It has nearly limitless memory, is difficult to crash, and works at extremely fast speeds. It's not a Mac or a PC; it's the human brain. And scientists around the world want to mimic its abilities.
The television version of George R.R. Martin's "A Song of Ice and Fire", named after the first book "Game Of Thrones" returns to television this Sunday. Like the books, it is full of War Of The Roses-style intrigue, indiscretions and, of course, swords.
By modifying the CRISPR-Cas genome editing system, researchers are now able to manipulate Candida albicans' genome systematically--an approach that could help identify novel targets for therapies against this serious pathogen for which there are a limited number of anti-fungal agents.
A test that costs less than a $1 and yields results in minutes has been shown in newly published studies to be more sensitive and more exact than the current standard test for early-stage prostate cancer.
The simple test developed by University of Central Florida scientist Qun "Treen" Huo holds the promise of earlier detection of one of the deadliest cancers among men. It would also reduce the number of unnecessary and invasive biopsies stemming from the less precise PSA test that's now used.
In 2005, scientists studying tiny sac-like creatures called sea squirts found bacteria containing two types of chlorophyll (a and b) in cavities inside the squirts' tissues. These two pigments were soaking up most of the sunlight -- the violets, indigos, blues, green, yellows and oranges.
New research suggests that when brains are organized into modules they are better at learning new information without forgetting old knowledge. The findings not only shed light on the evolution of intelligence in natural animals, but will also accelerate attempts to create artificial intelligence (AI).
A blood test undertaken between 10 to 14 weeks of pregnancy may be more effective in diagnosing Down syndrome and two other less common chromosomal abnormalities than standard non-invasive screening techniques, according to a multicenter study led by a UCSF researcher.
Humans have evolved to be incredibly efficient at walking. In fact, simulations of human locomotion show that walking on level ground and at a steady speed should theoretically require no power input at all.
But anyone who works on their feet or has taken an arduous hike knows otherwise. In fact, people expend more energy during walking than any other activity in daily life, and for the elderly and those with mobility issues, that energy can be precious.
A novel molecule designed by scientists at the University of Massachusetts Medical School and the University of Virginia inhibits progression of a hard-to-treat form of recurring acute myeloid leukemia (AML) in patient tissue. The small molecule is one of the first designed to specifically target a cancer-causing transcription factor. Previously thought to be an undruggable target, this strategy may be used to design other novel molecules that can specifically inhibit cancer-causing transcription factors. Details of the work were published in Science.
A blood test may help to predict which people will have severe allergic reactions to foods according to a new study led by Mount Sinai researchers and published online today in the The Annals of Allergy, Asthma & Immunology.
New research shows that paracetamol is ineffective in reducing pain, disability or improving quality of life for patients who suffer from low back pain or osteoarthritis of the hip or knee, and its use may affect the liver. The study in the British Medical Journal provides new evidence that paracetamol is no better at treating low back pain than a placebo and its effect on osteoarthritis of the hip or knee is too small to be clinically worthwhile.
High-fructose corn syrup is in just about every product on grocery store shelves so it is no surprise that something of a culture war sprang up against it - at least until the tables turned on sugar as well. Is one sugar that has a variable range of sugar really better than another sugar with a precise, even if lower, ratio of fructose? If fructose is bad, why isn't honey banned? Is bleached white table sugar the healthy alternative to anything?
