Animal,Porkey Pig, Lobund-Wistar (Photo credit: Wikipedia ) I would not allow my kids to be lab rats, but that is my decision as a father. What would yours be? ----- Advances in study, powerful tools have led to questions about impact on humans, society By Neo Chai Chin Jan 10, 2013 SINGAPORE - Should children be included in research on "smart drugs", or drugs that could improve their cognitive abilities? Should people lacking mental capacity be allowed to take part in genomic research? Does neuroscience research require more ethical safeguards than other types of biomedical research ? These are questions that the public is invited to mull over and provide feedback on, with the launch of a public consultation on Ethical , Legal and Social Issues in Neuroscience Research yesterday by the Bioethics Advisory Committee. Rapid advances in the study of the brain and the rest of the nervous system, as well as development of more powerful tools to explore and...

In Search of a better Water Heater

Image
English: Two Rannai brand, tankless water heaters in a commercial setting. Each unit is rated 199,000 BTU and the two work in parallel, heating water to 185 degrees Fahrenheit. Located on a dairy farm and provide hot water for cleaning milking equipment. (Photo credit: Wikipedia ) Tankless Water Heater   For decades, tankless water heaters have been used in Europe and other parts of the world where energy prices are steep. Most consumers in North America , however, were not aware of tankless water heaters until recently.   The happy surprise is that, compared with conventional water heaters, these on-demand water heaters can save energy and money and deliver an endless flow of hot water. In fact, installing a qualifying tankless water heater can save you money on your taxes through a $300 credit.   The familiar tank -style water heater is basically a large container with a heater. It stores a lot of water (typically 40 to 80 gallons), heats the water...

Later reproduction may extend offspring's life: study

Image
The finding is completely against the current belief - it therefore needs further study and more evidence. But if succeeding tests will yield the same results, there goes another myth... and this is a really, really good one indeed! Read on... ----- Posted: 12 June 2012 WASHINGTON : The offspring of fathers and grandfathers who reproduced later in life could enjoy life-extending genetic benefits, including being able to father children at an older age, a new study suggests. Researchers at Northwestern University believe the process represents an unusually rapid evolutionary adaptation in which telomeres -- DNA found at the ends of chromosomes -- lengthen, which is thought to promote healthy aging. "If your father and grandfather were able to live and reproduce at a later age, this might predict that you yourself live in an environment that is somewhat similar -- an environment with less accidental deaths or in which men are only able to find a partner at later ages,...

Grief boosts "heart-attack risk"

Image
There is a reason why "a merry countenance is good to the heart..." "There is a time for everything... ... a time to laugh, a time to cry..." ----- Posted: 10 January 2012 WASHINGTON : Grief over the death of a loved one can cause a huge spike in a person's risk of heart attack , especially in the early days after the loss, said a US study on Monday. The research tracked nearly 2,000 adults who survived a heart attack and found that among those who had just lost a loved one, the risk of a heart attack soared 21 times higher than normal in the first day. The risk rate remained six times higher than normal through the first week, and declined slowly over the course of the first month, said the findings in Circulation: Journal of the American Heart Association . Intense grief can cause a host of symptoms that raise heart risks, including higher heart rate, blood pressure, stress hormone levels and blood clotting. Grieving people are also prone to lo...

China faces sperm donor dearth

Image
This seems like an irony, in my opinion... China losing out on reproduction? ----- By Kristine Lim Posted: 15 November 2011 SHANGHAI, China: China faces a shortage of sperm donors , and the quality of sperm adds to the infertility problem as more couples seek out sperm banks. Only about five to 10 per cent of sperm donations make the mark. The hectic pace of life, stress at work, as well as a changing environment with more pollution and exposure to elements such as radiation affect fertility. In Shanghai, about 2,500 couples seek out the sperm bank each year. They can wait up to three years for a donor. Shanghai Human Sperm Bank head Li Zheng said: "If you come to the hospital and take a look at the men without sperm or who are infertile, you will see how much stress they have. "For me, it is really difficult to break the news that he cannot have children at the end of the treatment. "It is a huge blow to the men. They face a lot of pressure a...

Some birth control shows higher clot risk

Image
Posted: 28 October 2011 WASHINGTON: Some birth control products, including contraceptive pills , rings and patches for women, carry a significantly higher risk of blood clot than low-dose medications, US regulators said Thursday. The US Food and Drug Administration said in its review of studies that have included more than 800,000 women that the higher risks are posed by products such as the pill Yaz , the transdermal Ortho Evra patch, and the NuvaRing vaginal insert. All three methods are "associated with an increased risk of VTE (deep venous thrombosis) relative to the standard low-dose" pills, the FDA said. Featured in the study were pills that contain drospirenone, as opposed to another type of progestin known as levonorgestrel. Some brand names include Yaz, Yasmin, Beyaz, Ocella , Loryna, Gianvi, Safyral, Syeda and Zarah. Yaz is the second biggest selling product made by the German pharmaceutical giant Bayer, with 1.56 billion in global sales. NuvaRing is...

US doctors discourage videos for babies under two

Image
Now this is really an eye-opener; we've known this for some time, but i think many more don't know this. So how about the iPad ? I've heard parents say that it is a 'boost' to their child's learning the alphabets and numbers. Maybe it is just the videos after all. Think so? ----- Posted: 18 October 2011 WASHINGTON: Watching television or videos is discouraged for babies under age two because studies suggest it could harm their development, a US paediatricians ' group said on Tuesday. Instead of allowing infants to watch videos or screens, parents should talk to them and encourage independent play, said the first guidelines issued in more than a decade by the American Academy of Paediatrics. The advice is the same as that issued in 1999 by United States' largest association of paediatricians, but this time it also warns parents of how their own screen-watching habits may delay their children's ability to talk. "This updated policy ...
