Danger of Heart Attack After Losing a Spouse

It seems people don't live on after their partner passes away. There is a higher risk of survivors getting a heart attack in the months after losing a husband or wife. It is believed to be due to the increased heart rate from the loss. If the living partner can get through the danger period the risk dissipates.

This shows that people who lose partners need medical help and support from friends and relatives during the grieving process. Doctors should pay special attention to cardiac symptoms. Persistent stress and depression should also be monitored.

The research involved people aged from 33 to 91, so this tendency affects spouses of any age. Subjects wore 24 hour monitors. Heart rate was closely observed. Periods of rapid heart beat occurred during the grieving period. Overall heart rate was also higher compared to people who had not had a loss.

Depression was four time higher than the norm in subjects. This persisted for several years.

Dinosaur Metabolism Was Faster Than Mammals

Dinosaur metabolism was not only higher than reptiles, their bodies ran at a faster rate than mammals. Analysis of tiny holes in their bones shows that they pumped a lot of blood through their bodies.

So scientists have been wrong for a long time claiming that dinosaurs were slow moving creatures who relied on the sun to get going each day. Tests across a wide range of dinosaurs, big and small, confirm they moved around with ease. Some scientists have accepted the hypothesis that dinosaurs were not reptiles.

It makes one wonder how many other things we are taught at schools are totally wrong. New evidence for upright walking of apes goes back more than four million years to an animal with feet designed to climb trees. Their hips are clearly designed for walking upright. And for decades we had been told a special foot design was necessary for bipedal walking.

Atheists Are Bad Citizens

Atheists are bad people. New findings show religious people contribute more to the community than non-believers. Apparently those who have no faith just get on with their lives caring only for themselves. But there is a saying "all of my best friends are atheists." They could be friendly. However, they have little drive to help society in a general sense.

Considering religious citizens believe in the writings of books that "command" believers to help others this finding is hardly surprising. Saying that such people are "nicer" though is too simplistic. Moreover, a fellow soldier who does not believe is just as likely to take a risk to save you in a battle as a religious person.

Atheists also give less to charity. Considering most charities are religious institutions, this is to be expected as well. Is the behavior of believers really altruistic? They are trying to get into heaven after all. Belief is a fickle thing. Even atheists have faith. They have faith that God does not exist.

Culling of Camels in Australia's Outback Is Misplaced

Where there's money to be gained someone will jump in. This is now the case for camels in Australia. Plans are being made to kill the animals in exchange for carbon credits. It is claimed that their flatulence is polluting the atmosphere.

Northwest Carbon apparently believes it owns the camels or has the sole right to cull them. The Department of Climate Change and Energy Efficiency first suggested taking such action. Apparently, one camel produces a ton of carbon dioxide each year. This is an exaggeration.

Culling camels has nothing to do with reducing Australia's carbon footprint. It is just a money-making exercise. Admittedly camels are feral. They were introduced into Australia in the 19th century because they were ideal for moving goods about in the dry outback. But their metabolism is higher than cattle and their pollution level is low.

Kelp Can Be Used to Make Biofuel

Biofuel can just be picked up as you go for a walk. Yes, and there's plenty of it. It's plain old kelp, particularly the Laminaria digitata type which grows along the coast of Wales. The plant's carbohydrate level peaks in July. A high level of carbohydrate is needed to produce more ethanol.

There is so much kelp in the world lying around beaches. It would be rational to use this resource because little of it is used for human consumption. The plant is very dense in its growth. Much more biomass per square meter is produced than with sugar cane or other ethanol crops.

Using prime agricultural land to grow crops to produced ethanol directly affects the supply and price of food. The oceans have almost limitless resources waiting to be utilized.

Mary River Turtle in Danger From Global Warming

Australia has a rare turtle restricted to the Mary River in Queensland. The University of Queensland has concluded that global warming will seriously endanger this species. Eggs were collected and incubated at 26, 29 and 32 degree Centigrade. Young turtles from eggs incubated at the highest temperature stayed in shallow water because they had difficulty swimming.

Life expectancy would be short for these young. Food is in deeper water and there is safety from predators. The Mary River turtle, Elesor macrurus, is classed as endangered. Numbers have been falling for several decades. Other dangers to their survival are eggs being collected to the pet trade and introduced predators such as dogs and foxes.

It is suspected that other species of turtle are similarly affected. Circumstances for the Mary River turtle are particularly dire because nests are in shallow water which can be directly affected by a warming atmosphere.

DNA Tests on Coconuts Show They Have Been Used by Man for a Long Time

The mystery of coconuts is solved. This useful fruit has been used for centuries. Besides being a healthy food it can be used as a carrying container, made into charcoal, its fibre used to make rope and it will save your life if appropriately adapted as a flotation device.

DNA tests have been done on coconuts worldwide. They have been spread around so much by people transporting them in their travels that they are quite homogeneous by type. There are only two main kinds: one from the Indian Ocean region and the other from the Pacific. Tall types predominate. The dwarf coconut accounts for only 5 per cent of all coconuts.

Both types of coconuts are used for different purposes. The niu vai is the usual kind with sweet juice inside. Copra is obtained from the niu kafa. One mystery still remains. While their are two distinct types, Madagascar has a variety that is a combination of the Pacific and Indian Ocean types.

Australian and US Institutions Work Together on Biofuels

Despite claims that growing crops for fuel is pushing up food prices the University of Queensland and Carolina's Clemsen University have signed an agreement to develop biofuels. The work will revolve around transforming sugar cane residue into fuel using algae. A pilot plant is to be built in Queensland. More research on cellulosic monomer conversion will be done.

Clemsen University has concentrated on converting sorghum and switchgrass into ethanol. A new base called loblolly pine is also being examined.

This combined project will benefit both institutions. Pooling funding and resources will speed up projects. Despite possible drawbacks of biofuel it is intended to seek further funding and press on with research.
