Health watch

first_imgThe Food Standards Agency (FSA) has launched new TV adverts to encourage shoppers to opt for healthy eating by using traffic light labels. They come as an international study names the UK as the number one fast food nation.The TV ads, voiced by comedienne Dawn French, were aired during GMTV breaks this month. They remind shoppers that they can find red, amber and green labels on many bakery products, which make healthy eating easier.The study, by global market research firm Synovate, found that 45% of those surveyed in the UK agreed with the statement: “I like the taste of fast food too much to give it up”, closely followed by the US on 44% and Canada 37%.The global survey looked at weight management among more than 9,000 people across 13 countries on five continents. Synovate’s global head of media Steve Garton said the survey had revealed conflicting attitudes. He explained: “People are inherently contradictory, and nowhere is it more obvious than on such a sensitive and important issue as their weight. The results show there’s a world of people who cannot deny themselves that hamburger or extra piece of pizza, but make themselves feel better by washing it down with a diet cola.”Around a third regularly weigh themselves, with 15% of the French and 12% of Americans weighing themselves every day.last_img read more

The complex relationship between heat and ozone

first_img Sea temperature patterns predict extreme temperatures Related Earlier warnings for heat waves This increase could lead to more respiratory illnesses, with especially dangerous consequences for children, seniors, and people suffering from asthma.“Short-term exposure to ozone has been linked to adverse health effects,” said Loretta J. Mickley, a co-author of the study. “High levels of ozone can exacerbate chronic lung disease and even increase mortality rates.”While temperature has long been known as an important driver of ozone episodes, it’s been unclear how increasing global temperatures will impact the severity and frequency of surface level ozone.To address this question, Shen and Mickley — with co-author Eric Gilleland of the National Center for Atmospheric Research (NCAR) — developed a model that used observed relationships between temperature and ozone to predict future ozone episodes.Previous research had not relied so heavily on existing observations, making projections uncertain. Shen and co-authors analyzed ozone-temperature relationships at measurement sites across the United States, and found them surprisingly complex.“Typically, when the temperature increases, so does surface ozone,” said Mickley.“Ozone production accelerates at high temperatures, and emissions of the natural components of ozone increase. High temperatures are also accompanied by weak winds, causing the atmosphere to stagnate. So the air just cooks and ozone levels can build up.”However, at extremely high temperatures — beginning in the mid-90s Fahrenheit — ozone levels at many sites stop rising with temperature. The phenomenon, previously observed only in California, is known as ozone suppression.California, the Southwest, and the Northeast would be the most affected, each possibly experiencing up to nine additional days of dangerous ozone levels, with much of the rest of the country experiencing an average increase of 2.3 days.In order to better predict future ozone episodes, the team set out to find evidence of ozone suppression outside of California and test whether or not the phenomenon was actually caused by chemistry.They found that 20 percent of measurement sites in the United States show ozone suppression at extremely high temperatures. Their results called into question the prevailing view that the phenomenon is caused by complex atmospheric chemistry.“Rather than being caused by chemistry, we found that this dropping off of ozone levels is actually caused by meteorology,” said Shen. “Typically, ozone is tightly correlated with temperature, which in turn is tightly correlated with other meteorological variables such as solar radiation, circulation, and atmospheric stagnation. But at extreme temperatures, these relationships break down.”“This research gives us a much better understanding of how ozone and temperature are related and how that will affect future air quality,” said Mickley. “These results show that we need ambitious emissions controls to offset the potential of more than a week of additional days with unhealthy ozone levels.”This research was supported by the NASA Air Quality Applied Sciences Team and the National Institute of Environmental Health Sciences. If emission rates continue unchecked, regions of the United States could experience between three and nine additional days per year of unhealthy ozone levels by 2050, according to a new study from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) published in Geophysical Research Letters.“In the coming decades, global climate change will likely cause more heat waves during the summer, which in turn could cause a 70 to 100 percent increase in ozone episodes, depending on the region,” said first author Lu Shen, a Ph.D. candidate at SEAS and the Graduate School of Arts and Sciences.California, the Southwest, and the Northeast would be the most affected, each possibly experiencing up to nine additional days of dangerous ozone levels, with much of the rest of the country experiencing an average increase of 2.3 days.last_img read more

JOBS project to be officially launched in Dominica Thursday

Share Tweet EducationLocalNewsTertiary JOBS project to be officially launched in Dominica Thursday by: – January 19, 2012center_img Share 28 Views   no discussions Photo credit: thewestindiannews.comThe University of the West Indies will on Thursday officially launch the Job Opportunities for Business Scale-Up (JOBS) project in Dominica.Project Manager Audra Stevenson Drakes says its aim is to support the growth of an entrepreneurial culture and diversifying the service-oriented economies of Barbados and the Eastern Caribbean. “It focuses on three major areas: human capacity building, institutional capacity building and research initiatives. It is hoped that through developing these areas Barbados and the OECS collectively will become a hub for innovation and entrepreneurship. It terms of building human capital, there are several training program that have evolved from the project. We are also looking to ensure that those who teach entrepreneurship have all the tools they need,” she said.The JOBS project is funded and coordinated by the United States Agency for International Development (USAID) and is expected to benefit the Organization of Eastern Caribbean States over the next three years. Drakes said one of the first initiatives that will get underway following the official launch is a young entrepreneurship competition.“It will be a regional competition that will encourage anybody between the ages of 18-35 who is a member of a tertiary institution to let us know what their idea is and there will be cash prizes available so they could take their business plan further. We have also developed a short term workshop that we will make available to persons in Dominica at no charge,” she said.The official launch will be held at the Fort Young Hotel and will begin at 3:00 p.m. Dominica Vibes Newslast_img read more

Padres prospect Anderson Espinoza has second Tommy John surgery

first_imgHe was assigned to Single-A Lake Elsinore, but said he started to feel discomfort in his elbow. It appears that the ligament-transplant graft in his elbow blew out, requiring additional reconstruction.He last pitched in a game in 2016, when he went 1-3 with a 4.73 ERA, 28 strikeouts and a 1.42 WHIP in 32 1/3 innings at full-season Single-A.It’s a huge blow for Espinoza, who was signed out of Venezuela in 2015 by the Red Sox but was then traded to the Padres as part of the Drew Pomeranz deal. Padres prospect Anderson Espinoza has experienced another big setback.The 21-year-old right-hander — rated the No. 13 overall prospect by MLB.com — underwent a second Tommy John surgery after his elbow issues continued, according to The San Diego Union-Tribune. Esponiza will miss the rest of the 2019 season and likely a large chunk of 2020, too, per the report.MORE: Watch ‘ChangeUp,’ a new MLB live whiparound show on DAZN“It’s brutal,” Padres general manager A.J. Preller said. “He’s put in a ton of time and effort. He put a lot work into it and obviously having to redo the surgery and potentially miss another year … he’s handled it as good as you can. I’m proud of him. He’s staying positive. He knows he’s got a long road in front of him and he’s going to work hard at it again.“We’ve had a lot of conversations explaining the belief we have in him. It’s not an easy process.”Espinoza underwent his first Tommy John surgery in August 2017 and appeared on track to return to the mound at the end of April or beginning of May.last_img read more
