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.

Researchers discover largest assemblage of ancient human footprints

Researchers discover largest assemblage of ancient human footprints

A team of anthropologists claimed to have discovered the largest assemblage of ancient human footprints in the northern part of Tanzania, Africa.

Cynthia Liutkus-Pierce and her colleagues found nearly 400-odd footprints, covering a tennis court-size area. The footprints in question were imprinted in deposits made by an ancient flood, dried, subsequently covered up with a layer of mud, which preserved them for nearly 19,000 years.

Humans will never get older than 115: study

Humans will never get older than 115: study

Humans have been living to surprisingly great ages over the past many decades but a new study has suggested that we have reached the upper limit of human longevity.

On August 4, 1997, Jeanne Calment died in a nursing home in France at age of 122 years, setting a world record for human longevity. Researchers believe that humans will likely not see the likes of her again.

A team of researchers at the Einstein College of Medicine in New York has concluded that the maximum lifespan for humans is probably 115 years.

Skeletal remains on Antikythera shipwreck could shed light on mysterious voyage

Skeletal remains on Antikythera shipwreck could shed light on mysterious voyage

A shipwreck present off the coast of the Mediterranean island of Antikythera in Greece is considered to be one the most mysterious shipwrecks in history. A team of international archaeologists has now come up with new information, human remains, which may shed light on the 2,000-year-old shipwreck.

The researchers from the Hellenic Ministry of Culture and the Woods Hole Oceanographic Institution (WHOI) have found a partial skeleton around 50 meters below the surface. The team thinks that the discovery may help provide information on what led the ship to sink.

Human eye capable of detecting smallest units of light, photons

Human eye capable of detecting smallest units of light, photons

You may not believe it, but human eyes have high sensitivity and can even detect photons. It means that human eye can see individual particles, a thing that even high-tech machines face trouble in detecting.

A new research has found that human eye is able to detect the smallest unit of light known as photons. Study’s lead researcher Alipasha Vaziri from Rockefeller University said that the eyes can detect photons under super-dark conditions. The cells in our eyes that can detect light are known as rod cells, which become sensitive in the dark.
