Contaminants called polycyclic aromatic hydrocarbons from oil spills can be toxic to wildlife, especially when in combination with ultraviolet radiation from the sun. New research on species native to the Gulf of Mexico indicates that, compared with oil exposure alone, co-exposure to oil and natural sunlight reduces survival rates of fish that spend time close to the surface in their larval stage.
Vitamin D supplementation improved symptoms of autism in a recent trial.
A new analysis points to surprisingly low rates of serious impacts from medication errors affecting nursing home residents, despite the fact that these errors remain fairly common.
The Stock Trader's Almanac 2017 (Wiley; October 2016; 978-1-119-24775-3; $50; Spiral-bound paperback and E-book) is the 50th update to the indispensable trader's and investor's resource. Yale Hirsch released the first edition of The Stock Trader’s Almanac & Record 1968 in the fall of 1967. Yale discovered or created some of the most iconic cycles, patterns, strategies, and indicators on Wall Street. Brokers, advisors, money managers, and individuals alike endorsed the book and clamored for more. Over the next five decades, Yale and Jeffrey Hirsch solidified their position as thought leaders in behavioral finance and market analysis.
Implantable Catalyst Against Cancer: Biocompatible heterogeneous copper catalyst for click chemistry in living organisms
Assembling a drug from harmless components at the target location, such as a tumor, would help reduce the side effects of treatment. In the journal Angewandte Chemie, British and Malaysian scientists present a new, nontoxic catalyst made of copper nanoparticles that can be used to specifically and selectively assemble building blocks in a living system. It was shown to be possible to make an anti-tumor drug from two benign components in situ.
John Wiley and Sons, Inc. (NYSE: JWa and JWb), today announced the names of its fourth cohort of Wiley Faculty Fellows—a select group of distinguished faculty from the network of Wiley Education Services partner universities. These Fellows have helped catalyze innovation in teaching and learning on their respective campuses.
Scientists have recently discovered a new bohaiornithid bird specimen from the Early Cretaceous Period of China with remarkably preserved feathers. Bohaiornithid birds belonged to enantiornithes, a group of avian dinosaurs that lived millions of years ago.
Within the criminal justice community, an approach to community supervision known as Honest Opportunity Probation with Enforcement (HOPE) has generated widespread enthusiasm and praise as a way to reduce substance use, violations, new arrests, and revocations to prison, while also leading to significant cost savings for local justice systems. A new study casts doubts on the benefits of HOPE over probation as usual (PAU), however.
Safe Fog: Phosphorus nitride could be used as a friction-stable, fast-burning, and very effective pyrotechnic obscurant
Safety combined with power and effectiveness is one of the most important targets in the development of pyrotechnic obscurants. In the journal Angewandte Chemie, German and Polish scientists introduced phosphorus nitride as a safe but very powerful alternative to the well-known red phosphorus formulations, which have been used in military and civilian applications for decades.
Sex-Related Differences in the Brain May Affect Pathways to Substance Abuse in Adolescents with Bipolar Disorder
A new study has found that adolescents suffering from bipolar disorder are more likely to develop substance use disorders if they have lower gray matter volume in the brain, a clue that can help in the design of better methods for early detection and more targeted prevention and treatment.
In a study of 736 asthma patients in Singapore, good asthma control resulted in a saving of S$65 (US$48) per physician visit. Compared with an average cost of S$214 (US$158) per visit, this reduction represents a cost saving of 30% versus suboptimally controlled asthma.
Following decades of clinical research largely excluding females, scientists are finding that there are large differences in men and women that go well beyond their reproductive systems. Now, the Journal of Neuroscience Research is dedicating an issue entirely to sex differences at all levels of the brain, from the genetic and epigenetic level, to the synaptic, cellular, and systems levels.
A new analysis indicates that many men with prostate cancer obtain second opinions from urologists before starting treatment, but surprisingly, second opinions are not associated with changes in treatment choice or improvements in perceived quality of prostate cancer care. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings also explore motivations for seeking second opinions, and suggest that second opinions may not reduce overtreatment in prostate cancer.
New research suggests that physical fitness, body mass index (BMI), IQ, and stress resilience in young adulthood may have effects on the risk of developing amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease.
In a population-based Canadian study of children with epilepsy, each of whom had access to universal health care, those from poor families had the same medical course and remission rate as their wealthier counterparts, but they had a less favorable social outcome as adults.
In a study of healthy postmenopausal women, reproductive life events related to sex hormones, including earlier age at menarche, later age at last pregnancy, length of reproductive period, and use of oral contraceptives were positively related to aspects of cognition in later life.
Some animals, such as the axolotl salamander, have the ability to generate large numbers of eggs—or oocytes—throughout life. Investigators who recently conducted detailed analyses of the axolotl provide insights on the mechanisms of ovarian regeneration that could assist regenerative medicine in treating pre-mature ovarian failure and reduced fertility in humans.
Salty Batteries: Sodium-oxygen batteries have improved cycle life due to highly concentrated electrolytes
Smartphones, laptops, electric cars—whatever the device, an efficient battery is high on any user’s wish list. The search for the next-generation battery has recently focused on sodium– oxygen batteries. Theoretically, these should provide previously unattainable efficiency but their practical implementation has proven to be a stumbling block. Researchers now report in the journal Angewandte Chemie, that a highly concentrated electrolyte solution may make the sodium–oxygen battery more stable, and therefore more practicable.
A new study found that speech difficulties are linked with difficulties in learning to read when children first start school, but these effects are no longer apparent at 8 years of age.
