An interdisciplinary team of researchers led by Northeastern University has developed a novel method for controllably constructing precise inter-nanotube junctions and a variety of nanocarbon structures in carbon nanotube arrays. The method is facile and easily scalable, which will allow the researchers to tailor the physical properties of nanotube networks for use in applications ranging from electronic devices to CNT-reinforced composite materials found in everything from cars to sports equipment.

BOZEMAN, Mont. -- Peak tornado activity in the central and southern Great Plains of the United States is occurring up to two weeks earlier than it did half a century ago, according to a new Montana State University study whose findings could help states in "Tornado Alley" better prepare for these violent storms.

Tornado records from Nebraska, Kansas, Oklahoma, and northern Texas – an area of high tornado activity dubbed "Tornado Alley" -- show that peak tornado activity is starting and ending earlier than it did 60 years ago.

MIAMI – A recent study of the global carbon cycle offers a new perspective of Earth's climate records through time. Scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science suggest that one of the current methods for interpreting ancient changes in the concentration of carbon dioxide in the atmosphere and oceans may need to be re-evaluated.

September 16, 2014 -- While abnormalities in the adrenergic and noradrenergic systems, both integral in the fight-or-flight response, are thought to play a role in the development of post-traumatic stress disorder (PTSD), until now there has been no genetic evidence of this connection. A collaborative study just released by researchers at Columbia University's Mailman School of Public Health and the University of Michigan found an interaction between the ADRB2 gene and childhood adversity.

We have all seen a peacock show its extravagant, colorful tail feathers in courtship of a peahen. Now, a group of researchers have used a special camera developed by an engineer at Washington University in St. Louis to discover that female northern swordtail fish choose their mates based on a similar display.

San Francisco, September 15, 2014—Patients with inoperable, early-stage lung cancer who receive stereotactic body radiation therapy (SBRT) have a five-year survival rate of 40 percent, according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 56th Annual Meeting. Such a positive survival rate is encouraging considering that historically conventional RT resulted in poor tumor control for patients with inoperable lung cancer.

The amazing variety of human faces – far greater than that of most other animals – is the result of evolutionary pressure to make each of us unique and easily recognizable, according to a new study by University of California, Berkeley, scientists.

Research using data collected from around 4,000 healthy people in the UK has enabled scientists to identify a rare genetic variant that dramatically reduces levels of certain types of lipids in the blood. The study is the first to emerge from the UK10K Project's cohort of samples from the general public and demonstrates the power of whole genome sequencing at scale.

Researchers have found evidence that genetic factors may contribute to the development of language during infancy.

Scientists from the Medical Research Council (MRC) Integrative Epidemiology Unit at the University of Bristol worked with colleagues around the world to discover a significant link between genetic changes near the ROBO2 gene and the number of words spoken by children in the early stages of language development.

San Francisco, September 15, 2014— For patients with locally advanced pancreatic cancer, the combination of chemotherapy and stereotactic ablative radiation (SABR) may be a promising treatment option, ultimately allowing them to undergo surgery that may not otherwise be an option, according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 56th Annual Meeting.

Dairy is considered part of a healthy diet and dietary guidelines recommend the daily consumption of 2-4 portions of milk-based products such as milk, yogurt, cheese, cream and butter.

"The only trials in which the female spent long time periods swimming near the replica was when the mate was yellow," Porfiri said. "In the presence of a yellow male, the females were actively engaged, swimming parallel to the replica and darting back and forth between the mate and the nest," he said, referring to a sheltered section of the tank.

San Francisco, September 16, 2014—A large, international analysis of patients with stage IV non-small cell lung cancer (NSCLC) indicates that a patient's overall survival (OS) rate can be related to factors including the timing of when metastases develop and lymph node involvement, and that aggressive treatment for "low-risk" patients leads to a five-year OS rate of 47.8 percent, according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 56th Annual Meeting.

Scientists could soon better predict a man's risk of getting prostate cancer after a worldwide team of researchers carried out the largest-ever analysis of the cancer's genetic biomarkers, reported in Nature Genetics today.

QUT Institute of Health and Biomedical Innovation's Dr Jyotsna Batra and Distinguished Professor Judith Clements, who led the Australian researchers in the large consortia of research hubs around the world, said the teams analysed more than 10 million genetic markers in 80,000 men.
