Exposure to Chemicals at Work Can Cause Chronic Disease
Your job can kill you or make you ill. If you work where chemicals are going into the air during the day you can get serious chronic disease. Twin "partners" were employed where they were exposed to trichloroethylene (TCE) and perchloroethylene (PERC). Many developed Parkinson's disease, where the brain stops producing dopamine leaving the sufferer with impaired balance, slowed movement and stiffness.
Though inherited genes can be a factor, environmental factors cause those without the genes to get the disease. Ninety nine pairs of twins were evaluated. Hobbies and work environments, smoking and head injuries were studied. Of the six suspect chemicals TCE, PERC, carbon tetrachloride, n-hexane, xylene and toluene, TCE and PERC were identified as the main contenders for causing Parkinson's.
Those who worked in machinery, dry cleaning and industrial areas where TCE and PERC are commonly used were in most danger. The two chemicals are shown to cause neurodegeneration in laboratory animals.

Climate Model Scientists Are in Decline
Climate models are presumed to be far too complicated for the layman to understand so they are left to the experts. However, the models save lives and valuable infrastructure. The complicated lines of code make predictions about future weather patterns.
Just a few decades ago weather could not be forecast for two days ahead. Currently, five day forecasts are common and they are reliable. Even seasonal outlooks are treated as valid. For examples, we have been told in Queensland that there will be a wet summer.
The all-seeing weather bureau is counted on to provide information about strong winds, hailstorms, cyclones and even the direction of forest fires.
To get an accurate prediction, up to date and correct data must be fed into the models. Computers are getting larger all the time and more complex models are being formulated. This is a complex job. Scientists need to draw on many specialized fields in physics, mathematics and computer science. No university offers a course teaching all these. Consequently, such gifted individuals must be sought rather than taught. The number of climate experts is declining.

Electric Motorcycles Are Popular
While electric cars have been slow to take off, electric motorcycles are in strong demand. Enthusiasts can't get their hands on new versions fast enough. Recently there have been improvements. The range was originally less than 100km. Now they will run for nearly 200km on each charge. Furthermore, they have a projected life of 500,000km. With a top speed of 110km per hour they are competitive for off-road competition.
New models can be used on-road and off-road. Costs are much the same as a conventional motorbike. Indeed, some are cheaper. Batteries are no longer a problem. They currently last the life of the bike. From a flat battery to fully charged in four hours is really convenient. Use two chargers and get going in two hours.
The latest shipment of new bikes to Australia sold out straight away. A popular electric motorcycle, the Zero, is made in California. Retail stores are opening across Australia. Unlike electric cars which are very expensive, electric motorcycles can be bought just for off-road fun. If you really like the experience a road model could be your next purchase. Professional racing could soon be on the cards.

Large Birds Are Scared Away by Low-Pitched Noise
You would think that birds are happy to live near humans as they can get easy access to food. Unfortunately, this is not the case, particularly for large birds.
Sound drives them away. Traffic noise and heavy machinery are the culprits. Larger birds use low-pitched songs to communicate. This is drowned out by engines and clunking machines.
Birds and nests were counted near natural gas wells. Compressors on the wells run day and night. The noise is like a reving motorcycle. Thirty species of bird were surveyed. The number of large birds was very low. Small birds have high-pitched songs that can still be heard over rumbling machinery, so their lives are unaffected.

Children and Women Are in Greater Danger of Brain Cancer From Cell Phones
Despite many tests there is no agreement on whether mobile phones cause brain cancer. Findings point to a trend in heavy phone users. Advice is given to use mobiles as infrequently as possible.
It is clear that the skulls of children are much thinner than adults and youngsters receive twice as much microwave radiation from cell phones as adults. Three times as much radiation is absorbed into children's hippocampus and hypothalamus. Other regions of their bodies in danger are the eyes and bone marrow.
Tests have mainly been carried out on adult males who have the thickest skulls of all. Scientists believe children and woman are in greater danger of getting brain cancer. One in four Australian women have reduced time spent on making calls in fear of brain damage. It is recommended that tests on children be used as the certifying method for phones.
While many scientists are not convinced, research shows that heavy phone users have a 40 per cent higher risk of getting gliomas, the most common brain cancer.

Being Fat Is Normal
People get fat because it is normal. Our ancestors had to go out and find food so they burnt up a lot of energy. It is modern society that is making us fat. Food is readily available, at arm's reach. Our bodies are preparing for the hard times that would inevitably happen in centuries past.
Being able to put fat on the body was a key to survival. That is why many dieters today are on a see-saw round of weight loss and weight gain. It is due to our hormones. When the body loses reserves hormones tell us to eat more. If you want to be slim you will have to put up with constant hunger. Work at the University of Melbourne has shown that hormone levels are indeed higher after people go on a ten week diet. It remains high up to a year later even though the dieting stopped nine months earlier.
There is hope. New products are coming onto the market that swell up in the stomach thus stopping the craving for food. Whether these are safe is another issue. They do offer money back if there is no weight loss in the first two weeks. Apparently they do work. Time will tell.

Pioneers Had More Children
People living in different places "breed" at different rates. Reasons put forward are level of income, education of women and access to contraceptives. Family size has also changed at various places in history. The adventurous ones who ventured far and wide had more children than those who remained in established urban centers. This is particularly the case for British and French settlers in North America.
Resources were more plentiful in new unsettled regions. For example, buffalo and native animals could easily be shot and eaten on the spot. New settlers were also healthier, being active for most of their lives. An examination of Canadian records since 1608 shows that couples on the outer edge of expansion had 20 per cent more children than those remaining in established regions. They also married younger. The pioneer contribution to the gene pool was four time greater than those who settled in populated areas. Church records were the main data source. If the number of illegitimate children were known the gene pool contribution could have been even higher.
Human growth in new expanses of virgin land is consistent with plant and animals. Weeds grow vigorously on new accessible land. Larger plants soon take hold as do small animals. The small animals also attract larger animals. Over time as life becomes denser reproduction rates decline. Saying that pioneers in the West grew like weeds is close to the truth. The spread of Mankind across the globe is no accident. It seems to be an evolutionary imperative.
