Can we save the strawberries? (video)
2015-08-03
(Press-News.org) WASHINGTON, Aug. 3, 2015 -- Strawberries are sweet, juicy and delightful. Unfortunately, an expiring federal pesticide exemption could mean 2016 will be the end of strawberries in the U.S. How can we protect our strawberries from pests and comply with federal fumigant standards? In this Speaking of Chemistry video, Sophia Cai explains the problem and some possible solutions. Check it out here: https://youtu.be/noaec9-BmwU.

(WASHINGTON, August 3, 2015) - The first protein engineered to help control bleeding episodes in patients with severe von Willebrand disease (vW disease) has been shown to be safe and effective, according to results of a Phase III trial. Study data were published online today in Blood, the Journal of the American Society of Hematology
When a blood vessel becomes damaged, a protein called von Willebrand factor (vWF) helps stop bleeding by guiding clot-forming platelets to the injury. vWF serves as the "glue" that helps platelets stick to a wound. Approximately 1 percent ...

Researchers at Northwestern University are using a novel dimensional method for distinguishing misbehavior that is expectable in early childhood versus that which is cause for clinical concern. Their study is published in the August 2015 issue of the Journal of the American Academy of Child and Adolescent Psychiatry.
Using a survey developed by the researchers to enhance precision of clinical identification in early childhood the Multidimensional Assessment Profile of Disruptive Behavior (MAP-DB), scientists obtained mothers' reports of their preschoolers' irritability ...

The World Glacier Monitoring Service, domiciled at the University of Zurich, has compiled worldwide data on glacier changes for more than 120 years. Together with its National Correspondents in more than 30 countries, the international service just published a new comprehensive analysis of global glacier changes in the Journal of Glaciology. In this study, observations of the first decade of the 21st century (2001-2010) were compared to all available earlier data from in-situ, air-borne, and satellite-borne observations as well as to reconstructions from pictorial and written ...

At a median follow-up of 10.9 years, an EORTC study has shown that irradiation of regional nodes in patients with stage I, II, or III breast cancer has a marginal effect on overall survival, the primary endpoint (at 10 years, overall survival was 82.3 % for regional irradiation versus 80.7% for no regional irradiation, (HR=0.87 (95%CI: 0.76, 1.00), p=0.06). The results published in the New England Journal of Medicine also showed that disease-free survival, distant-disease-free survival, and breast cancer mortality were significantly improved. Side effects were very limited, ...

People often mimic each other's facial expressions or postures without even knowing it, but new research shows that they also mimic the size of each other's pupils, which can lead to increased trust. The findings, published in Psychological Science, a journal of the Association for Psychological Science, reveal that participants who mimicked the dilated pupils of a partner were more likely to trust that partner in an investment game, but only when the partner was part of the same ethnic group.
"People generally underestimate the importance of pupils, despite the fact ...

Skin cancer is the most common of all cancers, and melanoma, which accounts for 2% of skin cancer cases, is responsible for nearly all skin cancer deaths. Melanoma rates in the US have been rising rapidly over the last 30 years, and although scientists have managed to identify key risk factors, melanoma's modus operandi has eluded the world of medical research.
A new Tel Aviv University study published in Molecular Cell sheds light on the precise trigger that causes melanoma cancer cells to transform from non-invasive cells to invasive killer agents, pinpointing the precise ...

Money can be a significant source of conflict in relationships, particularly during stressful times. New research from North Carolina State University details techniques romantic couples can use to address financial uncertainty, highlighting the importance of communication in managing uncertainty and reducing stress.
"Regardless of income level, I found that couples are uncertain about money--whether that's how to put food on the table or whether to sell a second home," says Lynsey Romo, an assistant professor of communication at NC State. "During tough financial times, ...

Compact optical transmission possibilities are of great interest in faster and more energy-efficient data exchange between electronic chips. One component serving this application is the Mach-Zehnder modulator (MZM) which is able to convert electronic signals into optical signals. Scientists of the KIT and the ETH in Zurich developed a plasmonic MZM of only 12.5 micrometers length which converts digital electrical signals into optical signals at a rate of up to 108 gigabit per second, and presented this device in the "Nature Photonics" scientific journal. (DOI 10.1038/nphoton.2015.127).
"Optical ...

The first comprehensive study of its kind finds weight cycling, repeated cycles of intentional weight loss followed by regain, was not associated with overall risk of cancer in men or women. The study by American Cancer Society investigators is the largest to date to investigate weight cycling with cancer risk. It appears early online in the American Journal of Epidemiology.
The authors of the report found weight cycling was not associated with overall risk of cancer in men or women after adjusting for body mass index and other factors. Weight cycling was also not associated ...

The brain is amazingly complex, with around 86 billion nerve cells. The challenge for researchers to create bench-top brain tissue from which they can learn about how the brain functions, is an extremely difficult one.
Researchers at the ARC Centre of Excellence for Electromaterials Science (ACES) have taken a step closer to meeting this challenge, by developing a 3D printed layered structure incorporating neural cells, that mimics the structure of brain tissue.
The value of bench-top brain tissue is huge. Pharmaceutical companies spend millions of dollars testing therapeutic ...
