Colorado's new alga may be a source of biofuel production

2013-05-28
(Press-News.org) A new strain of yellow-green algae, heterococcus sp. DN1, which may prove to be an efficient source for biodiesel, has been discovered in the snow fields of the Rocky Mountains. Research examining this new alga, published in Biotechnology Progress, reveals that H. sp. DN1 was found to grow at temperatures approaching freezing and to accumulate large intracellular stores of lipids. H. sp. DN1 produces the highest quantity of lipids when grown undisturbed with high light in low temperatures.

Algae that can grow in extreme conditions and accumulate lipids are of great interest to industry. The team found that as H. sp. DN1 produces the highest quantity of lipids when grown undisturbed with high light in low temperatures, it is a potential source of lipids for human nutrition when grown undisturbed, and it has an ideal lipid profile for biofuel production when stressed.

"We have isolated and characterized a new cold-tolerant lipid-producing strain of algae from the Rocky Mountains in Colorado, US," said Dr. David Nelson. "This may have implications for the commercial production of algal lipids at northern latitudes where the culture of other algal species is limited or impossible."

Study explores 100 year increase in forestry diseases

2013-05-28
As ash dieback disease continues to threaten common ash trees across Europe, new research in the Journal of Quaternary Science explores the historic impact of forest diseases to discover if diseases played a significant factor in vegetation change. The study explores how large-scale pathogen outbreaks were much more infrequent in the past, which suggests the human role in transporting pathogens to new locations, such as the international seed trade, is a major factor. "The temperate and boreal forests of Europe and North America have been subject to repeated pathogen ...

U of A medical researchers ID genetic marker for sporadic breast cancer

2013-05-28
Medical researchers at the University of Alberta have pinpointed a genetic marker for sporadic breast cancer – one of a handful identified to date in Caucasians. Researchers have identified many genetic markers for familial breast cancers, but not for sporadic breast cancer which accounts for 80 per cent of all cases. Sambasivarao Damaraju, a professor with the Faculty of Medicine & Dentistry and a researcher at the Cross Cancer Institute, worked with his team to scan the DNA of about 7,200 Alberta women, including those who have had sporadic breast cancer and those who ...

Research shows copper destroys norovirus

2013-05-28
New research from the University of Southampton shows that copper and copper alloys will rapidly destroy norovirus – the highly-infectious sickness bug. The virus can be contracted from contaminated food or water, person-to-person contact, and contact with contaminated surfaces, meaning surfaces made from copper could effectively shut down one avenue of infection. Worldwide, norovirus is responsible for more than 267 million cases of acute gastroenteritis every year. There is no specific treatment or vaccine, and outbreaks regularly shut down hospital wards and care ...

Childhood bullying increases the propensity to self-harm during adolescence

2013-05-28
A new study has proven that being bullied during childhood directly increases the likelihood of self- harm in late adolescence. The analysis, led by researchers from the University of Warwick in association with colleagues at the University of Bristol, highlights that being bullied at primary school age can cause enough distress to significantly increase the risk of self-harming in later adolescence. Almost 5,000 participants in the Children of the 90s study were assessed for exposure to bullying between seven and ten years of age and later asked whether they had engaged ...

Art appreciation is measureable

2013-05-28
Have you experienced seeing a painting or a play that has left you with no feelings whatsoever, whilst a friend thought it was beautiful and meaningful? Experts have argued for years about the feasibility of researching art appreciation, and what should be taken into consideration. Neuroscientists believe that biological processes that take place in the brain decide whether one likes a work of art or not. Historians and philosophers say that this is far too narrow a viewpoint. They believe that what you know about the artist's intentions, when the work was created, and ...

Bees tell birds to buzz off

2013-05-28
VIDEO: This shows the methods used in the playback experiment. Click here for more information. A new study highlights the 'parasitism by theft' of bumblebees that invade birds' nests and claim them as their own. Their warning buzz helps bumblebees to "scare" the bird away from the nest. The work by Piotr Jablonski and colleagues, from the Laboratory of Behavioral Ecology and Evolution at Seoul National University in South Korea, is published online in Springer's journal, Behavioral ...

Einstein's 'spooky action' common in large quantum systems

2013-05-28
Entanglement is a property in quantum mechanics that seemed so unbelievable and so lacking in detail that, 66 years ago this spring, Einstein called it "spooky action at a distance." But a mathematician at Case Western Reserve University and two of his recent PhD graduates show entanglement is actually prevalent in large quantum systems and have identified the threshold at which it occurs. The finding holds promise for the ongoing push to understand and take advantage of the property. If harnessed, entanglement could yield super high-speed communications, hack-proof ...

Just how secure is quantum cryptography?

2013-05-28
Quantum communication systems offer the promise of virtually unbreakable encryption. Unlike classical encryption, which is used to send secure data over networks today and whose security depends on the difficulty of solving mathematical problems like the factoring of large numbers, most quantum encryption schemes keep the encryption key separate from the data. This approach ensures that an eavesdropper with access only to the data could not decipher the key. However, researchers have recently demonstrated that even quantum encryption may be susceptible to hacking. In ...

IU study: Unique omega-3 source effective at reducing exercise-induced asthma symptoms

2013-05-28
BLOOMINGTON, Ind. -- An Indiana University study has found that a unique omega-3 supplement derived from the New Zealand green-lipped mussel significantly improved lung function and reduced airway inflammation in asthmatics who experience exercise-induced bronchoconstriction, also called exercise-induced asthma. Timothy Mickleborough, professor in the IU School of Public Health-Bloomington, said his findings are similar to his studies involving fish oil but required a much smaller dosage of the supplement. His new study, appearing online in the journal Respiratory Medicine, ...

UNC scientists identify possible KRAS downstream target for pancreatic cancer therapy

2013-05-28
CHAPEL HILL, N.C. - While the mutated KRAS oncogene is associated with many cancers, it has not yet been successfully targeted by a therapeutic agent. Scientists are trying to find another way to target the gene by blocking signals from another protein downstream. A University of North Carolina School of Medicine team offers first evidence of the role of a protein called GSK-3 alpha in promoting oncogenic KRAS function. When the scientists inhibited GSK-3 in a model of pancreatic tumors, the team got a strong anti-tumor response, thus offering a potential therapeutic ...
