Science is the best thing that has happened to humankind because its results can be questioned, retested, and demonstrated to be right, or even wrong, says the Guardian newspaper. Science is not about proving at all cost some preconceived dogma
But, some of the most high profile findings in social sciences of the past decade do not stand up to replication, a major investigation has found. The project, which aimed to repeat 21 experiments that had been published in Science or Nature – science’s two preeminent journals – found that only 13 of the original findings could be reproduced.The replications were high powered, with sample sizes on average about five times higher than in the original studies.These results show that ‘statistically significant’ scientific findings need to be interpreted very cautiously until they have been replicated even if published in the most prestigious journals,” said Magnus Johannesson of the Stockholm School of Economics, one of the project leaders.
Similar results have been found in other fields. In 2015, an impressive collaboration of 270 investigators working for five years published in Science the results of their efforts to replicate 100 important results that had been previously published in three top psychology journals. The replicators worked closely with the original authors to make the repeat experiments close replicas of the originals. The results were bleak: 64% of the experiments could not be replicated. https://goo.gl/YMUJEF
A professor said coconut oil is “pure poison” and because she is affiliated to Harvard University everyone is running around like chickens without heads. Well, my response is this: why have a billion Indians, Pakistanis, Bangladeshis and Sri Lankans who use coconut oil daily for cooking not been poisoned?? In those countries they also apply coconut on their hair as routine and regular treatment.
For about 200 years Seychellois used coconut oil for cooking and we are still around, albeit more obese and probably sicker but not because of coconut oil.
My family’s company Jivan Jetha & Co, produced refined cooking oil from coconuts, famously known as “Jivans Cocoil”. This factory closed down when cheap palm oil from the Far East flooded the market. That was probably the early beginnings of obesity and related health problems, now hugely exacerbated by junk food and a sedentary life style.
Melissa Majumdar, a spokesperson for the U.S. Academy of Nutrition and Dietetics has said coconut oil is fine in moderation. “My message is that we can eat coconut oil,” Majumdar said, “but to be mindful of how it fits into our daily life.”
Consumption of meat is increasing at a faster rate than the world population. On a global scale the per capita consumption and the total amount of meat consumed are higher than ever before. This is bad news for the environment and our health, a report, published in the Journal of Science, says.
Two main factors are responsible. The world’s population is increasing which drives overall demand up, and individual incomes are rising so more people can afford to eat meat
There are various harmful effects on the environment. Rearing livestock produces higher carbon emissions than growing vegetables, fruits and grains. Currently, livestock production is responsible for 15% of all carbon dioxide, methane and nitrous oxide emissions.
Animal production contributes to a loss of biodiversity, as forests and untamed land are turned into agricultural fields to grow animal feed.
Another area of concern is human health. Meat is a good source of nutrients for low-income households, but a meat-heavy diet has been linked to incidents of colorectal cancer and cardiovascular disease.
It’s becoming more and more evident that the trajectory of Seychelles’ Blue Economy is heavily dependant on geopolitics in our region. Who the big regional players are and whether they are advocates of sustainability and equity (2 key pillars of the Blue Economy) will be determining factors in the take-off or crash and burn of the Blue Economy.
As Seychelles signed up to China’s Belt and Road Initiative this week, against the background of its controversial decision to allow India to develop a naval base on Assumption island, it becomes the latest Indian Ocean nation to stumble into the power play of these 2 super- powers in this region.
Now, Japan has signaled that Tokyo is wading into the Indian Ocean, with Japanese Defense Minister Itsunori Onodera’s groundbreaking trip to Sri Lanka this week.
Japan has a strategic interest in Sri Lanka’s Hambantota Port. It reflects its “free and open seas” policy, which calls for a rules-based maritime system to ensure stability and prosperity.
Japan is looking to close ranks with India and Singapore and also develop Sri Lanka’s northeastern port of Trincomalee, the world’s second-deepest natural harbor, as a counterweight to China.
It’s therefore not a coincidence that Japan has this week officially announced it’s intention to open an Embassy in Seychelles.
Seychelles, and other smaller countries, which walked a tightrope between the US and the Soviet Union during the Cold War must prepare for another difficult balancing act as larger countries continue to move into this (once again) strategically important region.
Let us hope that the Blue Economy will not be sacrificed on the altar of geopolitical expediency.
A new study following 112,000 participants shows that taking omega-3 supplements has little or no effect on cardio-vascular diseases, disproving claims that using them improves heart health. Moreover, in my view, the production of omega-3 supplements has a major impact on marine ecosystems because they are made mostly from millions of small fish like menhaden, anchovies and krill that are key in maintaining marine food webs. Take home message: consuming omega-3 capsules does not reduce heart disease, stroke or death but their production is aiding and abetting in the destruction of the environment
Coastal communities in developing countries cannot be food secure because 78% of fishing in their Exclusive Economic Zones is by vessels of rich nations, a new study shows. A whopping 97% of all high seas industrial fishing comes from developed nation’s vessels. The new study reveals the global dominance of industrial fishing by wealthy nations.
Yesterday I was in a meeting about HR development in Seychelles where a business man got up and spoke for 30 minutes on laziness in the work force. But, if research is anything to go by, his workers may live longer than he does
A new study of fossil and living marine shells from the Atlantic Ocean suggests “laziness” may be a successful strategy for survival of individuals, species and even communities of species. The researchers found a difference for marine shell species that have gone extinct over the past 5 million years and ones that are still around today. Those that have gone extinct tend to have higher metabolic rates than those that are still living. In other words, those that have lower energy maintenance requirements seem more likely to survive than those organisms with higher metabolic rates, say the researchers.
This contrasts with recent research on Homo erectus, which suggests groups of this early human became extinct because of “least effort” strategies. Are we Men or are we Snails?
