Perceived poor managerial leadership increases not only the amount of sick leave taken at a workplace, but also the risk of sickness amongst employees later on in life. The longer a person has had a "poorer" manager, the higher his or her risk of for example suffering a heart attack within a ten-year period, according to a new thesis from the Swedish medical university Karolinska Institutet. http://www.physorg.com/news176397399.html Medicine & Health Mon, 02 Nov 2009 15:50:02 EST news176397399 It's common sense: Stay home from work if you have the H1N1 flu virus. But the reality of making that happen is daunting for already-lean businesses in Minnesota as they grapple with just how flexible they can be with sick leave. And while some employees can work from home or have a bank of sick time, many -- particularly those on the front lines in food or retail -- are afraid to call in sick for fear they'll lose their jobs or are hesitant to lose a day's pay. http://www.physorg.com/news172917309.html Medicine & Health Wed, 23 Sep 2009 15:40:01 EST news172917309 Walking outdoors in the fall, the splendidly colorful leaves adorning the trees are a delight to the eye. In Europe these autumn leaves are mostly yellow, while the United States and East Asia boast lustrous red foliage. But why is it that there are such differences in autumnal hues around the world? A new theory provided by Prof. Simcha Lev-Yadun of the Department of Science Education- Biology at the University of Haifa-Oranim and Prof. Jarmo Holopainen of the University of Kuopio in Finland and published in the Journal New Phytologist proposes taking a step 35 million years back to solve the color mystery. http://www.physorg.com/news169376021.html Biology Thu, 13 Aug 2009 09:54:18 EST news169376021 Self-sustaining organisms like plants possess the ability to synthesize their own food using inorganic materials. Plants use water and carbon dioxide to begin this process in their green tissues. The leaf is the organ most often used by plants for this food synthesis. The Western Pacific Tropical Research Center is contributing to the general understanding of the strategies that plants employ to carry out this foundational step of the food web. http://www.physorg.com/news167563425.html Biology Thu, 23 Jul 2009 10:40:02 EST news167563425 (PhysOrg.com) -- Many animal species such as snakes, insects and fish have evolved camouflage defences to deter attack from their predators. However research published in New Phytologist has discovered that trees in New Zealand have evolved a similar defence to protect themselves from extinct giant birds, providing the first evidence of this strategy in plant life. http://www.physorg.com/news167477282.html Biology Wed, 22 Jul 2009 10:29:12 EST news167477282 Researchers from the Department of Science Education-Biology at the University of Haifa-Oranim have managed to make out the "self-irrigating" mechanism of the desert rhubarb, which enables it to harvest 16 times the amount of water than otherwise expected for a plant in this region based on the quantities of rain in the desert. This is the first example of a self-irrigating plant worldwide. http://www.physorg.com/news165669392.html Biology Wed, 01 Jul 2009 12:30:01 EST news165669392 (AP) -- Apple co-founder and CEO Steve Jobs appears to be a step closer to returning to work, as a doctor gave him an "excellent prognosis" after receiving a liver transplant at a Tennessee hospital. http://www.physorg.com/news165054526.html Technology Wed, 24 Jun 2009 10:00:03 EST news165054526 Apple chief executive Steve Jobs sounds healthy, a month before his scheduled return from a medical leave of absence, Apple co-founder Steve Wozniak was quoted as saying on Wednesday. http://www.physorg.com/news162671315.html Technology Wed, 27 May 2009 19:29:06 EST news162671315 Repeatedly going to work when ill significantly boosts the chances of having to take long term sick leave later on, reveals research published ahead of print in the Journal of Epidemiology and Community Health. http://www.physorg.com/news160275461.html Medicine & Health Thu, 30 Apr 2009 01:58:04 EST news160275461 Long-term leaves of absence tied to stress-related diagnoses are often preceded by a long period without any secure and comforting social relations. This is shown in a recently published study in public health science at Karlstad University in Sweden. http://www.physorg.com/news158489993.html Medicine & Health Thu, 09 Apr 2009 10:00:32 EST news158489993 Two new studies led by researchers at the University of California, Berkeley, suggest that taking maternity leave before and after the birth of a baby is a good investment in terms of health benefits for both mothers and newborns. http://www.physorg.com/news150346721.html Medicine & Health Mon, 05 Jan 2009 02:58:41 EST news150346721
