As heart disease continues to be a major killer in the United States, researchers have become keenly interested in identifying the potential risk factors that trigger heart attacks. High fat diets and life in the fast lane have long been known to contribute to the high incidence of heart failure. But according to new studies, the list of risk factors may be significantly longer and astonishing.
Heart failure, e. g. , appears to have seasonal and temporal patterns. A higher percentage of heart attacks occur in cold weather and more people experience heart failure on Monday than on any other day of the week. In additional, people are more prone to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid 1980 and have since discovered a number of potential causes. An early morning rise in blood pressure, heart rate and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between the hours of 8: 00 am and 10: 00 am. In other studies, both birthday and bachelorhood have been implicated as risk factors. Statistics prove that heat attack rate increases significantly for both females and makes in the few days immediately preceding and following their birthdays. And unmarried men are more at risk for heart attacks than their married counterparts. Though, stress is thought to be linked in some way to all of the aforementioned risk factors, intense research continues in the hope of future comprehending why and how heart failure is triggered.

If you have been missing the tweeting of sparrows around your house, here’s your chance to find out why this common bird seems to have disappeared from cities across India. A two months long online survey called citizen sparrow was launched inviting responses from people on questions such as when they last sighted the bird and details regarding the area where they used to live in.
“It is an elementary step to assimilate information. We are encouraging and motivating people to share their experience, be it a drastic drop in sparrow count or a sudden spurt. These data will give us valuable leads to compile pan-India data, ” said Suhel Quader, evolutionary ecologist at the National Centre for Biological Sciences. The disappearances of the house sparrow, so widespread till recently that the Chinese communist Party declared it a pest in 1958 and asked people to exterminate it, remains a great modern mystery world wide. In the UK, sparrows are estimated to have declined from over 12 million to 6 million, since the mid 80s.
“The survey would give us the first baseline data about distribution of sparrows in the country. This would form the basis for further research, ” said Karthik K, project coordinator. The sole aim of involving ordinary citizens inspite of experts comes with a purpose. ” Almost everyone knows about sparrow. It is an attempt to reach out to people, asking them to share their stories and their understanding of these birds, ” said Quader.
Participants in the survey would be asked to mark locations on a map and give information about their sparrow sightings, including sightings from last year and even earlier. Such information will enable a comparison of population of sparrows in different places and this is expected to point to particular threats or problems. The findings are intended to provide detailed studies, investigating reasons of decline in population and potential measures for recovery of population.
The sparrow is an indicator of a trend. A number of other birds have also declined sharply in the past few decades. The survey would provide more clues about why these birds are disappearing.
