    By: Kandil AA, AE Sharief, Ola S.A. Shereif Key Words: Canola, Cultivars, Salinity stress, seedlings characters. Int. J. Agr. Agri. Res. 8(2), 10-18, February 2016. Abstract To study the effect of salinity concentrations on seedlings parameters of some canola cultivars, a laboratory experiment was conducted at Agronomy Department Laboratory of Seed Testing, Faculty of Agriculture, Mansoura University, Egypt, during December 2013. The experiment included two factor, the first factor included three cultivars of canola i.e. Serw 4, Serw 6 and Serw 51 and the second factor included ten concentrations of salinity as NaCl i.e. 0.0 (control treatment), 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, and 1.8 % NaCl). The results showed that Serw 6 cultivar significantly exceeded the other studied cultivars in root and shoot lengths and shoot fresh and dry weights. Whilst, Serw 51 cultivar significantly exceeded the other studied cultivars in root fresh and dry weights, seedling height reduction (SHR), relative dry weight and chlorophyll content in leaves. Salinity stress significantly affected seedlings characters of canola. Due to increasing salinity levels from 0 (control) to 1.8% NaCl, seedlings characters of canola was significantly decreased. It could be concluded that for maximizing canola seedlings parameters, germinated seeds of Serw 6 or Serw 51 cultivars under control treatment (without salinity stress) or under conditions of 0.2% NaCl.

    "We often think that the limiting factors to doing science are intellectual or technological. There are many unsolved scientific problems that we know how to answer. We aren't waiting for any conceptual breakthroughs or new technologies. We're waiting for people. We need "hands at the bench" to put in the time to collect the data. The instabilities of salary is a major limiting factor for science and is probably a big reason a lot of them get out of science: they don't see a way to pay the bills. Creating permanent, stable positions for scientists would release a lot of scientific research."

    "Academics have to publish in high-Impact Factor journals to receive promotions, tenure, or grant funding, and universities allocate their million-dollar library budgets to those same high-Impact Factor journals. This is despite the Impact Factor's many known flaws - the most limiting of which is that the citations it is based on take 3-5 years to accumulate"

Dark Energy: Still a Puzzle | Cosmic Variance | Discover Magazine - 0 views

  •  
    People should not be afraid of dark energy. Remember that the problem with the cosmological constant isn't that it's mysterious and ill-motivated - it's that it's too small! The naive theoretical prediction is larger than what's required by observation by a factor of 10^120. That's a puzzle, no doubt, but setting it equal to zero doesn't make the puzzle go away - then it's smaller than the theoretical prediction by a factor of infinity.

    "The same technology could potentially be used for bladder and multiple myeloma cancers, which also shed identifiable markers in urine. "Our goal is a device the size of a home pregnancy test priced around $10. Other prostate cancer tests coming to market cost up to $4,000 each. The UC Irvine team made price a key design factor of their work..The UC Irvine team developed a new type of sensor: They added nanoscale protein receptors to tiny, pencil-like viruses called phages that live only within bacteria. Double wrapping the phages with additional receptors greatly increases the capture and transmission of cancer molecule signals."

    "Similarly, how should cancer biologists think about cancer cells capable of producing vascular endothelial growth factor, a protein that promotes the growth of blood vessels? Clearly, the importance of this protein only makes sense when thinking about a cancer cell's environment: how close it is to blood vessels that it can exploit, for example."

    "Here we show that four days of immersion in nature, and the corresponding disconnection from multi-media and technology, increases performance on a creativity, problem-solving task by a full 50% in a group of naive hikers. Our results demonstrate that there is a cognitive advantage to be realized if we spend time immersed in a natural setting. We anticipate that this advantage comes from an increase in exposure to natural stimuli that are both emotionally positive and low-arousing and a corresponding decrease in exposure to attention demanding technology, which regularly requires that we attend to sudden events, switch amongst tasks, maintain task goals, and inhibit irrelevant actions or cognitions. A limitation of the current research is the inability to determine if the effects are due to an increased exposure to nature, a decreased exposure to technology, or to other factors associated with spending three days immersed in nature."

Seasonal effects on suicide rates - Wikipedia, the free encyclopedia - 0 views

    "These findings clearly state that there is a relationship between summer suicide rates and biochemical (e.g., plasma L-TRP and melatonin levels, [3H]paroxetine binding to blood platelets), metabolic (serum total cholesterol, calcium and magnesium concentrations), and immune (number of peripheral blood lymphocytes and serum sIL-2R) variables.[18] Another study focused on the association between depression, suicide, and the amount of polyunsaturated fatty acids (PUFA). They state that "depression is accompanied by a depletion of n-3 poly-unsaturated fatty acids".[22] Their methodology involved taking periodic blood samples-every month for one year-of healthy volunteers, allowing them to analyze the "PUFA composition in serum phospholipids and [relating] those data to the annual variation in the mean weekly number of suicides". They used an analysis of variance (ANOVA) to document their results, finding that PUFA like arachidonic acid, eicosapentaenoic acid, and docosahexaenoic acid all occurred at significantly lower rates in winter than in summer months. The association between depression, suicide, and PUFA rates is indicative of there being a biological factor in seasonal effects on suicide rates"

Peter Lockhart: No proof gum disease causes heart problems - Health - CBC News - 0 views

  •  
    "For 20 years, researchers have reported a potential link between gum disease and atherosclerotic heart disease from hardening of the arteries or stroke. "The message sent out by some in health-care professions, that heart attack and stroke are directly linked to gum disease, can distort the facts, alarm patients and perhaps shift the focus on prevention away from well-known risk factors for these diseases," said Dr. Peter Lockhart, a professor and chair of oral medicine at the Carolinas Medical Center in Charlotte, N.C. Lockhart wrote the heart group's new position statement in the journal Circulation. The statement was prepared after a three-year analysis of about 600 studies by an expert panel led by a dentist and a cardiologist."

Gut Microbes May Foster Heart Disease | Wired Science | Wired.com - 0 views

    ""We probably have underestimated the role our microbial flora play in modulating disease risk," says Daniel Rader, a heart disease specialist at the University of Pennsylvania School of Medicine. Rader, who was not involved in the study, says that gut bacteria may not be as big a factor in causing heart disease as diabetes or smoking, but could be important in tipping some people toward sickness. Researchers led by Stanley Hazen, a cardiologist at the Cleveland Clinic, didn't start out to study gut bacteria. In fact, says Hazen, he had "no clue - zero," that intestinal microbes were involved in heart disease. "I'd never even considered it or thought of the concept." Hazen and his colleagues compared blood plasma from healthy people to plasma from people who had had heart attacks, strokes or died to see if substances in the blood could predict who is in danger from heart disease. The researchers found 18 small molecules associated with fat buildup in the arteries. One of the best predictors turned out to be a byproduct made when gut bacteria break down a fat called choline (also known as lecithin). The more of this byproduct, called trimethylamine N-oxide or TMAO, a person or mouse has in the blood, the higher the risk of getting heart disease, the researchers found. Gut bacteria are actually middlemen in TMAO production. The microbes convert lecithin to a gas that smells like rotten fish. Then an enzyme in the liver changes the foul-smelling gas to TMAO."

Anthony Ives, Stephen Carpenter: Stability and Diversity of Ecosystems - 0 views

  •  
    "Understanding the relationship between diversity and stability requires a knowledge of how species interact with each other and how each is affected by the environment. The relationship is also complex, because the concept of stability is multifaceted; different types of stability describing different properties of ecosystems lead to multiple diversity-stability relationships. A growing number of empirical studies demonstrate positive diversity-stability relationships. These studies, however, have emphasized only a few types of stability, and they rarely uncover the mechanisms responsible for stability. Because anthropogenic changes often affect stability and diversity simultaneously, diversity-stability relationships cannot be understood outside the context of the environmental drivers affecting both. This shifts attention away from diversity-stability relationships toward the multiple factors, including diversity, that dictate the stability of ecosystems."

    "This research provides an understanding of the neural basis for social behavior from the perspective of how we evaluate social experiences and how our social interactions and decisions are motivated. We review research addressing the common neural systems underlying evaluation of social and nonsocial rewards. The human striatum, known to play a key role in reward processing, displays signals related to a broad spectrum of social functioning, including evaluating social rewards, making decisions influenced by social factors, learning about social others, cooperating, competing, and following social norms.

What causes autism? Exploring the environmental contribution : Current Opinion in Pedia... - 0 views

  •  
    Purpose of review: Autism is a biologically based disorder of brain development. Genetic factors - mutations, deletions, and copy number variants - are clearly implicated in causation of autism. However, they account for only a small fraction of cases, and do not easily explain key clinical and epidemiological features. This suggests that early environmental exposures also contribute. This review explores this hypothesis. Recent findings: Indirect evidence for an environmental contribution to autism comes from studies demonstrating the sensitivity of the developing brain to external exposures such as lead, ethyl alcohol and methyl mercury. But the most powerful proof-of-concept evidence derives from studies specifically linking autism to exposures in early pregnancy - thalidomide, misoprostol, and valproic acid; maternal rubella infection; and the organophosphate insecticide, chlorpyrifos. There is no credible evidence that vaccines cause autism. Summary: Expanded research is needed into environmental causation of autism. Children today are surrounded by thousands of synthetic chemicals. Two hundred of them are neurotoxic in adult humans, and 1000 more in laboratory models. Yet fewer than 20% of high-volume chemicals have been tested for neurodevelopmental toxicity. I propose a targeted discovery strategy focused on suspect chemicals, which combines expanded toxicological screening, neurobiological research and prospective epidemiological studies.
