Drones Used to Control Sharks in Australia

Australians tend to be early adopters of new technology because they have inquisitive minds. Our old enemy, the shark, will always be around, so it is not surprising that drone technology is being used to solve this problem.

It is not the buzzing sound that will scare sharks off. Drones are being used to gather visual information about where sharks are and the number swimming around, the theory being that if we know this we can be more careful.

At the moment hooks are baited on lines attached to floating drums. This method is a simple way to catch sharks, but other creatures are also caught such as dolphins. Unfortunately, sharks not tempted by the bait remain in the area. Baited hooks have warning devices in them that notify watchers on a boat when sharks take them.

This is a clumsy way to keep sharks at bay. Targeting sharks observed by drones is a better solution. Drones are far cheaper than helicopters and do a better job, going right down to sea level to collect data.

Humans Crossing With Neanderthals and Denisovans is Rubbish

Much has been said about humans having mated with neanderthals. Scientists claim that all of us have Neanderthal genes. There is the real issue of humans and Neanderthal having a different number of chromosomes. It is known that if a horse is mated with a donkey, the result is an infertile mule. This holds true for all species, so how is it possible for two type of man who branched away from each other a very long time ago to have fertile offspring - the answer is it isn't possible.

Another issue is the premise that Denisovans mated with Man. There is little evidence for this. Currently, we do not know the number of chromosomes Denisovans had. Yet most scientists treat the mixing hypothesis as fact.

Can scientists be wrong? They have of course been very mistaken in times past and the present is no different. Why do specialists accept theories that have not been tested by the well know scientific method. It must be the case that most of them accept that Santa exists and lives at the North Pole.

There is another answer as to why Neanderthals, Denisovans and Humans have some of the same genes, but no one ever says it. We all have a common ancestor. Why couldn't there be some of the ancient genes from this ancestor present in each species?  Look in the mirror and see if you have a flat forehead and a large brow ridge.  You do?  Then join the club!

Insect Population Measured by DNA Analysis of Spider Webs

Spider webs are advanced pieces of evolutionary engineering. They are also collecting vats for what lives in the neighborhood. The DNA of what a spider had for dinner remains on the web for months.

Silk from spiders webs is in demand for potential pest management, conservation, biodiversity monitoring and biogeography. It is a natural source of accumulated data and analysis of it is informative. If the DNA makeup of a web changes then something is wrong.

In the tests, black widow spiders were kept alive by feeding them with crickets. When a spider died its DNA remained on the web for 88 days. In the wild, the net of the web catches insects, small animals and flora debris.

Going out and getting some web silk is proving to be a valuable way of monitoring changes in spider populations, particularly when new species move into an area. Importantly, an eye can be kept on those on the endangered list. The method is only good for small animals because large ones
take the whole web with them.
