Early Human Migration from Africa Could Have Started Much Earlier than Estimates: Research

Early Human Migration from Africa Could Have Started Much Earlier than Estimates: Research

Human migration from Africa could have started earlier than previously estimated 60,000 years ago, as per new research. As per “Out of Africa” theory on human migration, home sapiens migrated from Africa to Asian regions. Researchers have recently found fossils in southern and central China dating between 70,000 and 120,000 years ago.

Energy Saving LEDs contributing to Light Pollution

Energy Saving LEDs contributing to Light Pollution

LED lights save power and offer better lighting but they are also leading to light pollution, as per a new research led by Christopher Kyba from the GFZ German Research Centre for Geoscience. Households are shifting to LED lights as they offer more lumens for each watt of electricity they consume. The research report informed that artificially lit surface of Earth has been rising over the last few years. The research team estimates approximately 2.2 percent annual increase in the radiance of our planet can be attributed to artificial lighting.

Artificial light threatening pollination: Experts warn

Artificial light threatening pollination: Experts warn

A new study by a team of ecologists at the University of Bern has cautioned that artificial light is disrupting nocturnal pollination, threatening reduction in fruit production.

Almost everyone knows that small creatures like bees play a key role in pollination. However, few people are aware of the fact that nocturnal insects like beetles and flies also play a crucial role in the process.

Fathers Care More for Daughters Compared to Sons: Study

Fathers Care More for Daughters Compared to Sons: Study

Fathers pay more attention to needs of toddler daughters compared to sons, as per a new study published in the American Psychological Association journal. The study team noticed that fathers of young daughters make use of analytical language compared to men caring for a son. For boys, fathers use more of achievement-related language. The study team added that a father’s brain surely responds differently to a daughter as compared to a son.

Human sense of smell is as good as other mammals: Study

Human sense of smell is as good as other mammals: Study

Human sense of smell is much more powerful than it is usually given credit for, and it also plays a larger role in maintaining health and behavior than previously thought, according to a new study.

A team led by John McGann, a neuroscientist at Rutgers University-New Brunswick in New Jersey, found in the new review that humans’ sense of smell is just as good as that of other mammals.

Slender faced individuals 25% more likely to be left-handed: Study

Slender faced individuals 25% more likely to be left-handed: Study

A new study by a dentistry researcher from the University of Washington has suggested that people who have a slender lower face are nearly 25 per cent more likely to be left-handed.

The researchers reached the conclusion after analyzing data collected through three surveys comprising a total of 13,536 people across the United States.
Approximately 2,000 years ago a Greek physician had identified slender jaws as a marker for susceptibility of TB, and he supposedly turned out to be right. The new study also confirmed that.

Researchers find Neanderthal DNA in caves

Researchers find Neanderthal DNA in caves

A team of researchers has announced that the DNA of two extinct human relatives has been detected in the mud of ancient caves, even though those caves hold no skeletal remains.

Researchers found the genetic material of the Neanderthals and the mysterious branch of humans called the Denisovans in sediment samples collected from 7 archaeological sites in Belgium, Spain, Croatia, France and Russia.

The sediment samples colelcteed by the researchers form the seven archeological sites cover a time span from an estimated 14,000 to 550,000 years ago.

Neanderthals inhabited China before arrival of modern humans: Study

The Neanderthals inhabited China before arrival of modern humans: study

A fresh analysis of two skulls found in central China back in 2007 and 2014 has shed light on the ancient humans who inhabited the region before the arrival of modern humans.

While the Neanderthals’ existence in Europe and western Asia before the arrival of Homo sapiens has long been known to scientists, knowledge of equivalent populations of the Neanderthals in East and Central Asia has been scarce.

Ancient Neanderthal Still Influences our Genes

Ancient Neanderthal Still Influences our Genes

Neanderthal DNA still has a profound impact on our genes, as per a new analysis conducted by researchers. Modern human race in Europe and Asia inherits nearly 2 percent of their genome to Neanderthal DNA. However, researchers now claim that Neanderthal DNA has a strong impact on how our genes work today. Neanderthals went extinct nearly 30,000 years back but possibly due to interbreeding that happened between Home sapiens and Neanderthals, modern day humans have genetic connection with Neanderthals.

Human Settlement in Australia happened much earlier than previous estimates: Research

Human Settlement in Australia happened much earlier than previous estimates: Research

Human settlement in arid interior regions of Australia happened much earlier than previous estimates, as per a new research paper. The study team led by archaeologist Giles Hamm from South Australia’s La Trobe University has found certain objects in Warratyi rock shelter in the southern interior which date back to 49,000 years. The study estimates that humans settled in arid Australia nearly 10,000 earlier than previous estimates of human settlements in the region.
