I was amazed by this dog Rex because he was very gentle around my dogs when he came to visit me. They seemed to get along very well. I wanted to know more about the Shiba Inu. I had to investigate a little bit more about this breed of dog. I asked my brother because he owns 2 of them. I wondered why he was always getting over the fence. Also I wondered why he would run away when he was called to come home? I found out that a Shiba Inu will dart out if given half a chance. This is a dog breed that is very attached to his human family members and can't stand being isolated from them. To think of keeping a Shiba in the backyard or in the garage is a mistake because that bold, bright natured dog will create loud noise and be destructive in that situation. He will be charming and affectionate around his human family, but has a sense of humor about him when it comes to human commands. A Shiba Inu is very challenging to raise and train. A high-spirited, an independent spirit, has to alway...

A study performed by an international team led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, reports a link between exposure to blue light at night and higher risk of developing breast and prostate cancer. Blue light is a range of the visible light spectrum emitted by most white LEDs and many tablet and phone screens. The results have been published in Environmental Health Perspectives. "WHO's International Agency for Research on Cancer (IARC) has classified night shift work as probably carcinogenic to humans. There is evidence pointing to an association between exposure to artificial light at night, disruption of the circadian rhythm, and breast and prostate cancers. With this study we sought to determine whether night exposure to light in cities can affect the development of these two types of cancer", explains Manolis Kogevinas, ISGlobal researcher and coordinator of the study. "We know that depending on its intensity and wave length, artificial light, particularly in the blue spectrum, can decrease melatonin production and secretion", says Martin Aubé, physics professor at CÉGEP in Sherbrooke, Canada and study co-author. The study was conducted within the framework of the MCC-Spain project cofunded by the 'Consorcio de Investigación Biomédica en Red de Epidemiología y Salud Pública' (CIBERESP), and includes medical and epidemiological data of more than 4,000 people between 20 and 85 years of age in 11 Spanish regions. Indoor exposure to artificial light was determined through personal questionnaires, while outdoor levels of artificial light were evaluated for Madrid and Barcelona, based on nocturnal images taken by astronauts aboard the International Space Station. Results obtained for both cities show that participants exposed to higher levels of blue light had a 1.5 and 2-fold higher risk of developing breast and prostate cancer, respectively, as compared to the less-exposed population. Ariadna García, ISGlobal researcher and first author of the study, says: "Given the ubiquity of artificial light at night, determining whether it increases or not the risk of cancer is a public health issue". At this point, further studies should include more individual data using for instance light sensors that allow measuring indoor light levels. It would also be important to do this kind of research in young people that extensively use blue light emitting screens". "Currently, the images taken by the astronauts on the Space Station are our only way of determining the colour of outdoor lighting at a large scale, and the spread of blue light-emitting white LEDs in our cities", comments Alejandro Sánchez de Miguel, scientist at the Astrophysics Institute in Andalucía-CSIC and Exeter University.

During my childhood I was a cat person. We probably had about 6 or 7 cats before I graduated from high school. After meeting my husband in college, who had a dog, I quickly became a dog person. I figured out that I really liked dogs, but not just any dog; I liked large breed dogs. The bigger the better. The thought of owning a small dog, especially a Chihuahua was incomprehensible to me and something I said I would never do. My husband's dog, Zoe, lived with us for about 16 years. She was there as we navigated through our different life stages from being a couple, to getting married, and then having children. She passed away when the kids were in Kindergarten/Pre-K; about 6 years ago. Once she was gone we didn't really consider getting another dog. It was nice to be free and take off on adventures and vacations without having to worry about someone watching the dog. About a year ago we contemplated the idea of bringing a pet into our home. My husband thought it would be good fo...
Athletes who turn to ketogenic diets to help their performance in high-intensity, short duration sports may want to think again, according to new research from Saint Louis University. In a small study, Edward Weiss, Ph.D., associate professor of nutrition and dietetics at Saint Louis University, together with SLU graduate students Kym Wroble, R.D. and Morgan Trott, R.D., examined the exercise performance of 16 men and women after following either a low-carbohydrate ketogenic diet or a high-carbohydrate diet for four days. His team then tested the anaerobic exercise performance of the participants. The research team found that after following the ketogenic diet, the participants did not perform as well at the exercise tasks. "In popular discussions, the term 'ketogenic diet' often is used as a broader term for low carb diets, including Atkins," Weiss said. "However, the language is often confused. People often think low carb and high protein. Thi...
