Humans and Denisovans had Similar Fingers

The study describes tip right-hand little finger, separated rest finger bone excavated 1 years ago. A digital reconstruction complete finger bone, phalanx, reveals Denisovans’ fingers were much more similar modern humans expected. “I’m happy we get something out,” says Eva-Maria Geigl, palaeogeneticist Institute Jacques Monod Paris, co-led study. “So far there nothing, phalanx lost.” Mum’s Neanderthal, Dad’s Denisovan: First discovery ancient-human hybrid Her team sequenced DNA missing fragment show matched rest fingertip bone, used photographs reunite two pieces digitally.work published September Science Advances1. “It’s not going revolutionize knowledge Denisovan morphology, adds little piece,” says Bence Viola, palaeoanthropologist University Toronto Canada part team.

Jurassic Piranha Fossil is Earliest Flesh-Cutting Fish

The fossil of a piranha-like jurassic fish shows a flesh-slicing eating ability. The specimen was the first bony fish to have this capacity. Teeth were much like the South American piranha. However, the ancient creature lived in the ocean not in freshwater. People eat the piranha and say it tastes like other fish.

SDingo called Sandy
DNA of the pooch was analyzed by Professor Bill Ballard head of a group from the University of Arizona and NSW's universities. The team researched the DNA of a Dingo for determining the genes for domestication. The researchers benefitted from a cash prize for the win: the Pacific Biosciences SMRT Grant. They will spend this to test a portion of the premises recommended by Charles Darwin.   |_| sandy as dingo it go Domestication in sandy dingo dog dna |_| |_| travel news stories genes |_|    

It it easy to acknowledge Darwin's premise that dogs were specifically reproduced by Man to train them to be docile with humans.

The numbers of wild Canis lupus is diminishing: pet dogs frequently leave the cars of families exploring the outback to breed with pure bloods. Giving them a species name is not logical in my view. Considering they can readily mate with canines and have fertile young. The offspring are not "mules", a necessary requirement for naming.

Psychologists Make Up Research Findings

Yes, the truth is out!. All of those silly questionnaires you are made to fill out when you apply for a job to see if you are psychologically suitable are rubbish. There is no truth or relevancy in them. They are just made up. Measuring nothing is their purpose. People are now in jobs requiring skills that they do not have - they should be doing something else.
Psychology is based on belief wrong
Tests from three psychology journals show that measures for skills, memory, personality, learning and relationships were very weak indeed. There was no consistency with the real world. Manipulation of data wasn't the problem: claims and statements were made by writers when there was no foundational proof for them.   It seems that hearsay, myth, misconception and blatant lying are features of academic articles on psychology. Didn't we suspect this all along? Of course we did!

A top psychologist withdrew 50 academic papers because they had false conclusions. Research on ESP was found to have no data showing proof. Misrepresentation seems to be the cultural norm among psychologists. This is a bad state of affairs. Academics are supposed to be critically aloof with their findings, suggestions being used to instructively guide the community.

Australia Finds a New Species Again!

Just when you thought the game was over a new species has been identified in Australia. In the darkest depths of tropical north Australia where there are wild crocodiles roaming freely a new waterlily has been found.
Peony flora waterlilly flower
A team of Australians and representatives of Kew Gardens in London scoured the Western Australian land searching for something new. It is amazing that  it was not identified before. The water flower is a beautiful purple and white.

It was in an isolated spot situated in an oasis of water near Gibb River. The Kimberley region is surely the place to be with new dinosaur fossils located there. Botanists have given the waterlily a common name: peony flora. A scientific label will soon be determined.

The plant seems to be plentiful. A "pond" was completely filled with the pretty flower. Further searches in other water bodies brought to light many more. Oddly, a specimen of the Lilly has been at Kew Gardens and was believed to be a hybrid. Now it is official - it is a species in its own right.

Saccharin to Treat Cancer

Are you sweet enough? Maybe you are if you use saccharin. But wait! Are there other uses that this comforter can be used for? Scientists believe that it could treat cancer. The saccharin molecule deactivates carbonic anhydrase IX, a protein in aggressive cancers.
Sweet saccharin to treat aggressive cancers
Carbonic anydrase IX regulates PH so that cancer can more easily spread through the body. It is hoped that saccharin can change the PH level. If it is not at an optimum level the cancer can be successfully treated with radiation and chemo therapy.

Healthy tissues, except for the gastrointestinal tract, have no carbonydrase anydrose IX. Other carbonic anydrase proteins are there though. Molecules tested before blocked similar carbonic anydrase proteins which are present to make the body work. By tweaking the saccharin molecule it was discovered that it does not affect helpful anhydrase proteins.

Tests have begun on liver and breast cancer. These are currently on animals. If the research is successful work on humans will open a new road to treating aggressive cancers.

Bird Know What You Are Thinking - They Understand Behavior

Be careful the next time you quietly curse a magpie attacking you during breeding season. It may know what you are thinking. Why is it that the birds seem to know the personalities of individuals walking by? If you have fed them in the past they appear to remember you and let you go on by unhindered while swooping down onto the heads of other people.

Crows have been observed hiding food from other crows. This is not due to stress as was once believed. There is still contention between the two opposing groups of scientists. Tests on scrub jays it was claimed proved that they were hiding food from more dominant Jays. This was really a hypothesis, not real proof.

The other group claims that birds are conscious of others and what other may be seeing, like humans. In their tests bird were allowed to hide peanuts in a litter of corn cobs. If another bird was watching they later came back and re-hid the peanuts. When they buried peanuts on their own they rarely re-hid them.

This was the key finding - stress from stealing hidden peanuts should change behavior. It didn't! Birds were given a tray of ground cobs but an empty bowl with no peanuts. They were then given cobs and peanuts which they hid. Researchers stole all the peanuts from this tray.

The birds were split into two teams for study. One had peanuts, a new cob tray with the "sham" empty tray. The other had peanuts, a new cob tray with the "pilfered" tray. Stress from knowing that peanuts had been stolen earlier did not change behavior. Both teams of jays hid peanuts in the same way.

The "contra" group of scientists claimed that the sham tray with no peanuts stressed the birds just as much as the pilfered tray. Obviously, the scientific test for testing new scientific claims is not set on concrete. It can be bent for one's own purpose.

Gene Therapy on the Brain Dangerously Changes Neuron Structure

Gene therapy for brain injuries and illnesses may be a good thing, but this treatment changes the shape of brain cells. Researchers in Western Australia say there is nothing to worry about because damaged brain cells regenerate or live longer. They say this when there is no proof that in the long term everything will be alright.

They say it is wonderful how brains cells function better after nine months of treatment. Apparently, the neurons become round due to new growth-promoting genes that stimulate them. The fact that surrounding genes away from the treatment area also change is in my opinion something to worry about. Obviously, when this occurs it cannot be reversed.

Doctors admit that the way neurons deal with information after treatment is never the same again. Furthermore, they suspect that the long-term effects may not be beneficial to the patient. It is a good thing that researchers are looking for a way to stop gene therapy in its tracks if anything goes wrong.

Sweet Potato Is Being Improved

The sweet potato is a hotel counter-lunch filling. It is something you have when there is no other vegetable left. Most people eat it because it is on the plate. It's flavour can be described as sugary. The only vegetable anything like it is fresh baby peas that can be quite sweet. The sweet potato, however, is far too "sickly" for most palates. This humble vegetable is being revamped.

Researchers in Queensland are trying to find varieties that can be grown more economically and which are more suitable for consumers - diametrically opposed goals one would assume. They are looking for more brilliantly coloured kinds, a silly aspiration considering people don't eat colour. It is the taste that is the problem. Seeing pretty red, purple, orange and white skin while you are peeling them is hardly, well, "appealing". Scientists are saying the colours are exciting. Wow! They are also saying that there are interesting flavours. This claim is not soundly based because no formal taste tests have been done.

A fatter kind is being worked on. A quick perusal of the local greengrocer would indicate that size is not really an issue. There are some monsters out there already. Like giant pumpkins such monstrosities are usually only fit for the rubbish bin.

Those doing the study admit that the sweet potato being produced is of very high quality. If that is the case why bother working on improvements? Surely, research on more main-stream vegetables like the standard potato is more logical than trying to improve a vegetable that is at best only a fill-in on the dinner plate.
