Oldest stone tool discovered by scientists in Turkey

Oldest stone tool discovered by scientists in Turkey

The oldest stone tool ever discovered in Turkey suggests that early humans passed through Asia to Europe far earlier than previously thought.

Researchers discovered the stone tool, quartzite flake in ancient deposits of river Gediz, western Turkey. It dates back to approximately 1.2 million years.

DNA can Survive Re-entry from Space

DNA can Survive Re-entry from Space

A surprising and important discovery has been made by Swiss researchers: DNA can survive re-entry from space. The researchers of the University of Zurich applied ring-shaped plasmid DNA to the exterior surface of TEXUS-49 rocket, which blasted off in 2011.

The DNA was planned so that it would confer effects on other cells, for instance making bacterium resistant to antibiotics. The DNA was tested after recovery, with up to 35% retaining full functionality.

Cambridge University Library releases Charles Darwin’s Manuscripts

Cambridge University Library releases Charles Darwin’s Manuscripts

Cambridge University Library has publicized manuscripts that explained the development of Charles Darwin's theory of evolution. More than 12,000 images have been digitized by the university.

The images show the naturalist's journey from coining the term 'natural selection' to launch of the 'On the Origin of Species'. It is expected that the revelation will help the academic researchers across the world.

Daily Low-Dose Aspirin Therapy may not have Significant Heart-Health Benefits for Older People

Daily Low-Dose Aspirin Therapy may not have Significant Heart-Health Benefits for Older People

According to a new research, there is possibility that daily low-dose aspirin therapy may not provide significant heart-health benefits to older people.

The study involved over 14,000 Japanese people aged 60 to 85 years. Researchers found no major difference in heart-related deaths or non-fatal heart attacks and strokes between people who consumed aspirin and those who didn't.

DNA analysis of 37000-year-old Russian man indicates Neanderthal Interbreeding

DNA analysis of 37000-year-old Russian man indicates Neanderthal Interbreeding

The genetic analysis of a man who lived in Russia about 37,000 years ago is not only giving scientists details about the genetic history of Europeans but has also revealed about interbreeding that took place with Neanderthals more than 50,000 years ago.

Human activities responsible for drastic decline in Cheetah populations

Human activities responsible for drastic decline in Cheetah populations

Human activities are responsible for the drastic decline in cheetah populations over the past many decades, according to a new study by North Carolina State University biologists.

The study, published in Journal Science, revealed that the cheetah population in Africa has decreased 10 times, from 100,000 to just 10,000 in the past century.

Genetic make-up of present-day Europeans traced

Genetic make-up of present-day Europeans traced

A new study has revealed that the modern-day Europeans gene pool is a mixture of three ancestral groups, not two.

This research was conducted by the researchers from the University of Tübingen and Harvard Medical School, along with the scientists from the Centre for Cellular and Molecular Biology (CCMB), Hyderabad.

Neanderthals were more intelligent than previously thought

Neanderthals were more intelligent than previously thought

Researchers have revealed that they have found evidence to prove that Neanderthals were considerably more sophisticated than what was previously believed by many experts. The researchers reached at the conclusion after discovering engravings deep in Gorham's Cave in Gibraltar. The discovery provided the first Neanderthal cave etchings found anywhere in the world.

Novel GPS Technique to Track Location of Human Ancestors

Novel GPS Technique to Track Location of Human Ancestors

The genetic 'sat nav', a new technique in genetics has been discovered by international team of researchers that can help learn where the human DNA was formed. The groundbreaking technique would help to determine where the ancestor's resided in the past.

Researchers at the University of Sheffield in the UK named the novel technique as the Geographic Population Structure tool (GPS). As the name resembles, the novel genetic technique can be used to find out location of past ancestors.

Americans do not believe much in Scientific Discoveries

As per recent GfK Public Affairs & Corporate Communications survey, 30 percent of Americans believe that Big Bang actually happened with 51% questioning the theory. People raised their concern on the fact that universe was created 13.82 billion years ago and has been expanding rapidly ever since formation.

Survey involved online interviews of 1,012 adults with margin of sampling error of 3.4% points for all respondents. Science and Engineering Indicators Survey has been conducted for the past 34 years by the National Science Foundation.
