This article will highlight some of what researchers have discovered about this amazing organ and hopefully inspire the same awe in you and direct the glory to our infinitely powerful Creator who engineered it all. The human brain, and any animal brain for that matter, is an engineering marvel. When the researchers studied a seemingly simple microscopic soil worm called a nematode, they found the same level of efficiency. Even the positioning of individual nematode neurons was thoroughly optimized. Similar results were obtained for datasets on the positioning of entire brain regions in humans and other mammals. Vast Computational Power In , a group of Stanford University scientists published a new visualization technique based on targeting individual proteins involved in transmitting electrical brain signals. Just one synapse alone can contain about 1, molecular-scale microprocessor units acting in a quantum computing environment. An average healthy human brain contains some billion nerve cells connected to one another through hundreds of trillions of synapses.

Why almost all scientists believe in evolution: It is impossible to prove that the theory of evolution is absolutely true. The theory maintains that plant evolution, animal evolution and the major geological changes to the earth unfolded over billions of years. Thus, the full theory cannot be demonstrated in the laboratory. Processes like the rise of mountains and erosion are simply too slow to be observed during one person’s lifetime.

Elements of the theory e. But nobody was on hand to observe what the world and its life forms looked like hundreds of millions of years ago.

How Do Scientists Date Ancient Things?

These are K-Ar data obtained on glauconite, a potassium-bearing clay mineral that forms in some marine sediment. Woodmorappe fails to mention, however, that these data were obtained as part of a controlled experiment to test, on samples of known age, the applicability of the K-Ar method to glauconite and to illite, another clay mineral. He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages.

Evernden and others 43 found that these clay minerals are extremely susceptible to argon loss when heated even slightly, such as occurs when sedimentary rocks are deeply buried. As a result, glauconite is used for dating only with extreme caution.

Share this article Share But the price of progress was smog – urban areas became almost uninhabitable due to poor air quality from the fumes coming out of the factories. The Liverpool University scientists examined black moths from 80 sites across Britain and found they share some key genetic signposts. This led them to identify the region of a chromosome – the equivalent of one page in their genetic code book – as being responsible for the colour change.

Smokestacks from steel factories in Sheffield in the early 19th century The same region is one in which mutations produce hundreds of different wing colour patterns in many species and mutations that control the size of eyespots on butterfly wings. He added however that more research is needed to identify the exact DNA changes which led to the changes in colour. They only account for a few per cent of the total population in England and Wales. Robert Reed, an evolutionary developmental biologist at the University of California, who was not involved in the study, said:

Apparently, many people do — and now those lists are not so secret anymore. A series of studies on “relationship deal breakers,” published last year in the journal Personality and Social Psychology Bulletin, represents “the first systematic and comprehensive attempt to understand the traits that people avoid in their partners,” the team of social scientists behind the studies writes.

In one of those studies, the researchers asked a nationally representative sample of 5, single Americans to reveal which in a list of 17 things would be a “deal breaker” when considering a “committed relationship” with someone. The top three deal breakers for men and women were “disheveled or unclean appearance,” “lazy,” and “too needy. Respondents ranged in age from 21 to 76; older people tended to have more deal breakers than younger ones, and women tended to have more deal breakers than men.

Consider two methods of estimating the age of the moon which also produced near identical results:

Tree-Ring Dating Dendrochronology Dr. Ron Towner from the Laboratory of Tree-Ring Research at the University of Arizona explains the principles behind dendrochronology and why this dating method is valuable to archaeologists. Ron demonstrates how to accurately count tree-rings, and discusses the importance of patterns and master chronologies. Family trees, the tree of life, getting back to your roots…. But beyond the powerful imagery that trees give us to represent our history, what can trees actually tell us about the past?

Dendrochronology is the scientific method of tree-ring dating. Americans first developed it in the early 20th century and now “dendro” is a common method of chronology that is used by scientists all over the world. Dendrochronology has become a fundamental tool in science, for reinforcing and expanding on the timelines of historical and ecological events in the past.

Follow Electric cars could drive from London to Edinburgh on a single charge using a new battery technology being developed at Cambridge Univeristy, scientists have said. The lithium-air technology could be used to develop batteries that are a fifth of the cost and weight of current electric car batteries – enabling them to match the range of petrol and diesel cars.

Although real-world usage remains “at least a decade away”, scientists say they have overcome a number of obstacles to develop a working laboratory prototype of the battery. However, previous versions of the technology have been inefficient and unstable, tending to “die” after multiple charge and discharge cycles, or even develop faults that see them short-circuit and explode. The new Cambridge University design, which uses a carbon electrode made from graphene, overcomes these problems and has so far been recharged successfully more than 2, times.

Current lithium-ion batteries, used in laptops and smartphones, are light but have to be recharged often because of their low energy densities. Their capacity also deteriorates with age.

New Natural Selection: How Scientists Are Altering DNA to Genetically Engineer New Forms of Life

Love-hungry teenagers and archaeologists agree: But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes. Until this century, relative dating was the only technique for identifying the age of a truly ancient object. By examining the object’s relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.

Though still heavily used, relative dating is now augmented by several modern dating techniques.

Can you observe evolution happening? Because for many species, humans included, evolution happens over the course of many thousands of years, it is rare to observe the process in a human lifetime. Usually only laboratory scientists studying quickly reproducing life forms, like single-celled creatures and some invertebrates, have the opportunity to see evolutionary change happen before their eyes. All of us can and do experience the indirect effects of evolution nearly every day, however.

One of the more important evolutionary concerns facing humans today is the emergence of antibiotic-resistant microbes. A battle against bacteria that we have been winning with medicine for the last 50 years or so is now an even race, according to some scientists — because of the rapid rate of bacterial evolution. Similarly, the use of pesticides in agriculture has driven the evolution of resistant insects that require more or harsher chemicals to be killed.

Scientists studying Galapagos finches have seen evolutionary changes in beak size and shape in just a few years. Major evolutionary transformations take much, much longer.

The true benefits—and consequences—of synthetic biology will come as scientists move from mimicking nature in the lab to redesigning it. Imagine plants that change color in the presence of explosives or microbes that can secrete the scent of a long-extinct flower. All of those projects are underway at various stages, and the last target—writing an entire human genome—would be an epochal achievement for science, potentially opening the door to re-engineering the human body itself, making us healthier, smarter, stronger.

But the discovery of two fossils believed to be 7. At that time climate change had turned Eastern Europe into an open savannah which forced apes to find new food sources, sparking a shift towards bipedalism, the researchers believe. He is a member of the tribe of hominins and the direct ancestor of homo. Therefore, like humans, he has wide molars and thick enamel. But missing links will always exist , because evolution is infinite chain of subsequent forms.

Using computer tomography, they were able to visualise the internal structures of the fossils and show that the roots of premolars are widely fused. The lower jaw, has additional dental root features, suggesting that the species was a hominid. The species was also found to be several hundred thousand years older than the oldest African hominid, Sahelanthropus tchadensis which was found in Chad. Professor David Begun, a University of Toronto paleoanthropologist and co-author of this study, added: The team believe that evolution of hominids may have been driven by dramatic environmental changes which sparked the formation of the North African Sahara more than seven million years ago and pushed species further North.

They found large amounts of Saharan sand in layers dating from the period, suggesting that it lay much further North than today. The split of chimps and humans was a single event. Our data support the view that this split was happening in the eastern Mediterranean — not in Africa.
