How highly processed foods harm memory in the aging brain
- ScienceDaily
- 21/10/14 23:27
Four weeks on a diet of highly processed food led to a strong inflammatory response in the brains of aging rats that was accompanied by behavioral signs of memory loss, a new study has found. Researchers also found that supplementing the processed diet with the omega-3 fatty acid DHA prevented memory problems and reduced the inflammatory effects almost entirely in older rats.

Study could pave way for creating safer opioids
- ScienceDaily
- 21/10/14 23:27
Researchers may have an uncovered new answers on how to create safer opioids. Design a new opioid to bypass the part of brain that feels pleasure, but retain the analgesic properties, which make opioids one of the most effective pain relievers. Researchers looked at how opioids may have become so widely abused.
Monitoring glucose levels, no needles required
- ScienceDaily
- 21/10/14 23:27
Noninvasive glucose monitoring devices are not currently commercially available in the United States, so people with diabetes must collect blood samples or use sensors embedded under the skin to measure their blood sugar levels. Now, with a new wearable device less intrusive glucose monitoring could become the norm.
Molecular atlas of small cell lung cancer reveals unusual cell type that could explain why it’s so aggressive
- ScienceDaily
- 21/10/14 23:27
Stem-like cells that make up only a tiny fraction of the total cells in a lung tumor could be the key to stopping the disease's deadly spread, say researchers.
How long can fiber reinforced polymer sustain concrete structures? Scientists answer
- ScienceDaily
- 21/10/14 23:27
One potential cost-effective way to sustain ageing concrete subjected to harsh environmental conditions is to externally coat the material with fiber reinforced polymer composites. But few studies have looked at the durability of such strengthening. Now, researchers from Korea and the USA conduct a 13-year long experiment to find out.

- ScienceDaily
- 21/10/14 23:27
Scientists have explored different approaches to catalysis, a chemical process that plays an essential role in biological reactions, as well as many industrial applications. Chemical catalysts have been used in a variety of human applications, ranging from pharmaceutical development to biodegradable plastics and environmentally safe fertilizers. They may also advance the development of green...
How the brain ignores distracting information to coordinate movements
- ScienceDaily
- 21/10/14 21:41
Researchers have discovered how neurons in a small area of the mammalian brain help filter distracting or disruptive signals -- specifically from the hands -- to coordinate dexterous movements. Their results may hold lessons in how the brain filters other sensory information as well.
Genes play key role in exercise outcomes
- ScienceDaily
- 21/10/14 20:20
A new study has found that genes can explain up to 72% of the difference in outcome between people after a specific fitness exercise. The research involved data from 3,012 adults and has identified a number of specific genes which influence the outcomes of different physical activities.
The planet does not fall far from the star
- ScienceDaily
- 21/10/14 20:20
A compositional link between planets and their respective host star has long been assumed in astronomy. Scientists now deliver empirical evidence to support the assumption -- and partly contradict it at the same time.
New metalens focuses light with ultra-deep holes
- ScienceDaily
- 21/10/14 20:20
Researchers developed a metasurface that uses very deep, very narrow holes, rather than very tall pillars, to focus light to a single spot.
Pollution’s impact on child health
- ScienceDaily
- 21/10/14 20:20
Air pollution is known to harm children's respiratory health, but its specific impacts on infection rates have remained unclear. A new analysis provides evidence of a link between the two in low-income settings, and indicates one industry may play an outsized role in the problem.
'Broken heart' syndrome is on the rise in women
- ScienceDaily
- 21/10/14 20:20
Researchers have discovered two alarming trends in Takotsubo cardiomyopathy -- also known as 'broken heart' syndrome -- a condition that is often triggered by stress or loss and can lead to long-term heart injury and impaired heart function.
Big differences found in male and female jojoba plant sex genes
- ScienceDaily
- 21/10/14 20:20
Hot desert sex has resulted in major genetic differences between male and female jojoba plants -- one of only 6 percent of plants that require a male and female plant to reproduce. New research suggests male and female jojoba plants have diverged so much, that the jojoba plant has more novel sex genes than any other known living organism. The discovery may help researchers develop a DNA test to...
Aided by stem cells, a lizard regenerates a perfect tail for first time in more than 250 million years
- ScienceDaily
- 21/10/14 20:19
Lizards can regrow severed tails, making them the closest relative to humans that can regenerate a lost appendage. But in lieu of the original tail that includes a spinal column and nerves, the replacement structure is an imperfect cartilage tube. Now, a study describes how stem cells can help lizards regenerate better tails.
Early modern human from Southeast Asia adapted to a rainforest environment
- ScienceDaily
- 21/10/14 20:19
Although there has been evidence of our species living in rainforest regions in Southeast Asia from at least 70,000 years ago, the poor preservation of organic material in these regions limits how much we know about their diet and ecological adaptations to these habitats. An international team of scientists has now applied a new method to investigate the diet of fossil humans: the analysis of...
Expansion of wind and solar power too slow to stop climate change

- 21/10/14 20:19
The production of renewable energy is increasing every year. But after analyzing the growth rates of wind and solar power in 60 countries, researchers conclude that virtually no country is moving sufficiently fast to avoid global warming of 1.5°C or even 2°C. The article "National growth dynamics of wind and solar power compared to the growth required for global climate targets" was published in...
