Using ‘Raman’ optical technology, scientists can now produce images of brain tissue that is affected by Alzheimer’s disease. The images include the surrounding areas, already showing changes.

Neurobiology: The chemistry of memory

ScienceDaily News - Thu, 11/23/2017 - 09:54
Learning requires the chemical adaptation of individual synapses. Researchers have now revealed the impact of an RNA-binding protein that is intimately involved in this process on learning and memory formation and learning processes.

'Lost' 99% of ocean microplastics to be identified with dye?

ScienceDaily News - Thu, 11/23/2017 - 09:54
The smallest microplastics in oceans, which go largely undetected, can be identified more effectively with an innovative and cheap new method, report researchers. The new method can detect microplastics as small as the width of a human hair, using a fluorescent dye. Previous scientific field work surveys report that only 1% of the plastic waste in the oceans has been found. This new research could lead to discovering the missing 99%.

Climate change could increase volcano eruptions

ScienceDaily News - Thu, 11/23/2017 - 09:54
Shrinking glacier cover could lead to increased volcanic activity in Iceland, warn scientists in a new report.

Hunting for the finest droplet

ScienceDaily News - Thu, 11/23/2017 - 09:53
Modern passenger airplanes already consume less than three liters fuel per one hundred kilometers and passenger. Scientists are currently working on further improving this value. In addition, engineers plan to optimize the combustion process such that exhaust gas emission is reduced considerably. For this purpose, they use supercomputers and simulation methods that are usually applied for tsunami calculations or for water effects in computer games.

Highly charged molecules behave paradoxically

ScienceDaily News - Thu, 11/23/2017 - 09:53
Chemistry researchers have now discovered how certain small biomolecules attach to one another. The researchers’ study also overturns the standard picture – particles with the same electrical charge appear to be drawn together and not vice versa. The results may be important for the development of new drugs.

Flamingo feces and their way of walking stimulate organic matter filtering in saline wetlands

ScienceDaily News - Thu, 11/23/2017 - 09:52
The greater flamingo (Phoenicopterus roseus) facilitates microbial ‘filtering’ of organic matter in saline wetlands, thus improving water quality and reducing nitrogen loads by promoting denitrification, research concludes. This is a facilitating role these animals possess which was unknown until now.

Radiographs of Dolly's skeleton show no signs of abnormal osteoarthritis

ScienceDaily News - Thu, 11/23/2017 - 09:51
Original concerns that cloning caused early-onset osteoarthritis (OA) in Dolly the sheep are unfounded, report experts.

Key to regenerating blood vessels discovered

ScienceDaily News - Thu, 11/23/2017 - 09:43
A signaling pathway that is essential for angiogenesis, the growth of new blood vessels from pre-existing vessels, has been discovered by researchers. The findings may improve current strategies to improve blood flow in ischemic tissue, such as that found in atherosclerosis and peripheral vascular disease associated with diabetes.

China's reversing emission flows revealed by research

ScienceDaily News - Thu, 11/23/2017 - 09:43
The flow of China's carbon emissions has reversed, according to new research. The study estimates the carbon implications of recent changes in the country's economic development patterns and role in international trade since the global financial crisis.

Meadows beat out shrubs when it comes to storing carbon

ScienceDaily News - Thu, 11/23/2017 - 09:43
While the world focuses on controlling global warming caused by carbon dioxide emissions from fossil fuels, less attention has been paid to the capacity of vegetation and soils to take up and store carbon. A remote field site in the Norwegian mountains is improving our understanding of carbon cycling in high-latitude alpine areas.

Ocean floor mud reveals secrets of past European climate

ScienceDaily News - Thu, 11/23/2017 - 09:43
Samples of sediment taken from the ocean floor of the North Atlantic Ocean have given researchers an unprecedented insight into the reasons why Europe's climate has changed over the past 3,000 years.

New batteries with better performance, improved safety

ScienceDaily News - Thu, 11/23/2017 - 09:43
Currently the most important technology for batteries is the lithium-ion battery technology, but the technology is expensive and contains a flammable liquid. To satisfy the growing demand from emerging markets, researchers have devised a new battery prototype: known as "all-solid-state," this battery has the potential to store more energy while maintaining high safety and reliability levels.

Glucocorticoids offer long-term benefits for patients with Duchenne muscular dystrophy

ScienceDaily News - Wed, 11/22/2017 - 19:06
Glucocorticoids, a class of steroid hormone medications often prescribed to patients with Duchenne muscular dystrophy, offer long-term benefits for this disease, including longer preservation of muscle strength and function and decreased risk of death.

Four simple tests could help GPs spot pneumonia and reduce unnecessary antibiotics

ScienceDaily News - Wed, 11/22/2017 - 19:06
Testing for fever, high pulse rate, crackly breath sounds, and low oxygen levels could be key to helping GPs distinguish pneumonia from less serious infections, according to a large study.

By saving cost and energy, the lighting revolution may increase light pollution

ScienceDaily News - Wed, 11/22/2017 - 15:10
Municipalities, enterprises, and households are switching to LED lights in order to save energy. But these savings might be lost if their neighbors install new or brighter lamps. Scientists fear that this 'rebound effect' might partially or totally cancel out the savings of individual lighting retrofit projects, and make skies over cities considerably brighter.

EU trade ban brings down global trade in wild birds by 90 percent

ScienceDaily News - Wed, 11/22/2017 - 15:10
Trade of wild birds has dropped 90 percent globally since EU banned bird imports in 2005. A new study demonstrates how it decreased the number of birds traded annually from 1.3 million to 130,000. International trade of wild birds is a root cause of exotic birds spreading worldwide.

New approach to tracking how deadly 'superbugs' travel could slow their spread

ScienceDaily News - Wed, 11/22/2017 - 15:10
Using a real-world outbreak as a test case, a team combined patient-transfer data and whole-genome sequencing to identify hotspots for transmission of antibiotic-resistant bacteria.
