Experts successfully test a novel oil spill cleanup technology

Science Daily - Fri, 24/03/2017 - 2:49pm
Tests of a novel technology that can accelerate the combustion of crude oil floating on water demonstrated its potential to become an effective tool for minimizing the environmental impact of oil spills. The Flame Refluxer, developed by fire protection engineering researchers, could make it possible to burn off spilled oil quickly while producing relatively low levels of air pollutants.

In a sample of blood, researchers probe for cancer clues

Science Daily - Fri, 24/03/2017 - 2:49pm
One day, patients may be able to monitor their body's response to cancer therapy just by having their blood drawn. A new study has taken an important step in that direction by measuring a panel of cancer proteins in rare, individual tumor cells that float in the blood.

Seven months after Rio Olympics, Zika continues to plague babies in urban slums

Science Daily - Fri, 24/03/2017 - 2:49pm
The near-paranoia related to Zika leading up to the 2016 Rio Games could have been avoided by heeding the lessons of previous epidemics, argues a new study.

Surprising culprit in nerve cell damage identified

Science Daily - Fri, 24/03/2017 - 2:49pm
Scientists have implicated a specific molecule in the self-destruction of axons, the wiring of the nervous system. Understanding just how that damage occurs may help researchers find a way to halt it.

Scientists get closer look at living nerve synapses

Science Daily - Fri, 24/03/2017 - 2:49pm
The brain hosts an extraordinarily complex network of interconnected nerve cells that are constantly exchanging electrical and chemical signals at speeds difficult to comprehend. Now, scientists report that they have been able to achieve -- with a custom-built microscope -- the closest view yet of living nerve synapses.

Chance find has big implications for water treatment's costs and carbon footprint

Science Daily - Fri, 24/03/2017 - 2:49pm
A type of bacteria accidentally discovered during research could fundamentally reshape efforts to cut the huge amount of electricity consumed during wastewater clean-up. The discovery has upended a century of conventional thinking. The microorganisms -- 'comammox' (complete ammonia oxidizing) bacteria -- can completely turn ammonia into nitrates.

Astronomers identify purest, most massive brown dwarf

Science Daily - Fri, 24/03/2017 - 2:49pm
Astronomers have identified a record breaking brown dwarf (a star too small for nuclear fusion) with the 'purest' composition and the highest mass yet known. The object, known as SDSS J0104+1535, is a member of the so-called halo -- the outermost reaches -- of our galaxy, made up of the most ancient stars.

Big data approach to predict protein structure

Science Daily - Fri, 24/03/2017 - 2:48pm
Nothing works without proteins in the body; they are the molecular all-rounders in our cells. If they do not work properly, severe diseases, such as Alzheimer's, may result. To develop methods to repair malfunctioning proteins, their structure has to be known. Using a big data approach, researchers have now developed a method to predict protein structures.

Evolutionary advantage of the common periwinkle

Science Daily - Fri, 24/03/2017 - 2:48pm
A special kind of small sulfur-rich proteins, the metallothioneins, have an extraordinarily large capability for binding heavy metals. An international team of scientists has now discovered that the marine common periwinkle, which is widely considered a delicacy, contains the largest version of the protein found yet, with one additional cadmium-binding domain and a one-third higher detoxification capacity. This feature may help the snail survive in heavy-metal-polluted environments.

Lighting up antibiotic resistance

Science Daily - Fri, 24/03/2017 - 2:48pm
Carbapenems are among the 'antibiotics of last resort' and can fight infections for which other drugs have long lost their effectiveness. However, even carbapenem-resistant pathogenic strains have emerged over the last decades.

On the trail of Parkinson's disease

Science Daily - Fri, 24/03/2017 - 2:48pm
The molecular causes of diseases such as Parkinson's need to be understood as a first step towards combating them. Chemists recently succeeded in analyzing what happens when selective mutations of the alpha-synuclein protein occur -- a protein that is closely linked to Parkinson's disease.

Severe psoriasis predominantly affects men

Science Daily - Fri, 24/03/2017 - 2:48pm
The fact that men are overrepresented in psoriasis registers and consume more psoriasis care have long led researchers to believe that the common skin disease disproportionately affects men. A unique study with 5,438 Swedish psoriasis patients now reveals that women have a statistically significant lower incidence of severe psoriasis compared to men.

Hydrophobic proteins on virus surfaces can help purify vaccines

Science Daily - Fri, 24/03/2017 - 2:48pm
Through experimental and computational tests, new research expands on the theory of virus surface hydrophobicity. By being slightly water-repellent, the outer layers of proteins in virus capsids affect how it interacts with cells and the environment. Understanding this more can improve vaccine production and virus detection.

Amazon Wins $1.5 Billion Tax Dispute Over IRS

Slashdot - Fri, 24/03/2017 - 2:40pm
Amazon.com on Thursday won a more than $1.5 billion tax dispute with the Internal Revenue Service over transactions involving a Luxembourg unit more than a decade ago. From a report: Judge Albert Lauber of the U.S. Tax Court rejected a variety of IRS arguments, and found that on several occasions the agency abused its discretion, or acted arbitrarily or capriciously. Amazon's ultimate tax liability from the decision was not immediately clear. The world's largest online retailer has said the case involved transactions in 2005 and 2006, and could boost its federal tax bill by $1.5 billion plus interest. It also said a loss could add "significant" tax liabilities in later years. Amazon made just $2.37 billion of profit in 2016, four times what it made in the four prior years combined, on revenue of $136 billion.
