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.

Scientists privately discuss project aimed to make synthetic human genome

Scientists privately discuss project aimed to make synthetic human genome

Can you imagine future where babies are taking birth without needing biological parents? This is something scientists today are discussing secretly. They want to create synthetic human genome for which they would employ chemicals to make man-made version of all DNAs found in human chromosomes.

The issue inevitably brings concern in life sciences community because such a technique will introduce kinds of human beings that were never ever observed before. The project is yet an idea only. This would also make improvement in DNA synthesis.

Half-dozen Primate Fossils unearthed from China may solve Evolution of Primates

Half-dozen Primate Fossils unearthed from China may solve Evolution of Primates

Fossils of six new species discovered in China may shed light on evolution of primates. These furry creatures lived in southern China approximately 34 million years ago, as per a study conducted by a group of researchers.

The fossils are of six extinct primate species that were previously unknown, announced researchers on Thursday. Four of the creatures are alike lemurs of Madagascar, one seems like Philippines’ tarsiers, and the remaining primate species is similar to monkey.

Two research teams create new record by growing human embryos outside womb for around two weeks

Research teams have created a record by growing human embryos outside a woman’s womb for around two weeks. They had to stop the embryo development so they do not violate an international ethics standard.

It has happened for the first time that researchers have been able to reach so close to the 14-day rule. For the first time, the rule was proposed in 1979 and was adopted in many countries at which laboratory research on human embryos should stop.

Infections carried by ancient humans from Africa probably contributed to demise of Neanderthals

Infections carried by ancient humans from Africa probably contributed to demise of Neanderthals

A latest study has suggested that ancient humans, who had moved out of Africa, could have infected Neanderthals with herpes. There have been a number of theories regarding demise of Neanderthals. According to the researchers of the new study, the infections brought by humans from Africa could have led to that downfall.

They have identified many types of infections that probably had made the species of hominins sick. The infections include tapeworm infection, tuberculosis, stomach ulcers, and the specifically striking disease herpes.

Researchers carry out first in-depth genetic analysis of Neanderthal Y chromosome

Researchers carry out first in-depth genetic analysis of Neanderthal Y chromosome

A research paper published in the American Journal of Human Genetics has unveiled new facts about the relationship between Neanderthals and modern humans and genetic factors that have kept two lineages separate. Earlier research has indicated that modern humans and Neanderthals may have interbred at different times and at different regions.

In the study, researchers have completed the first in-depth genetic analysis of a Neanderthal Y chromosome. The Y chromosome was the main factor that was yet to be assessed from the Neanderthal genome.
