NEW LIGHT SHED ON THE PEOPLE WHO BUILT STONEHENGE

a day ago
Even before Stonehenge became Stonehenge, the beloved and mysterious sarsen monument we know today, it was an important place to the people of the Mesolithic and Neolithic that inhabited the region. Bone remains suggest it was once an important burial place for at least hundreds of years - and now a new analysis has shown that people travelled from as far as western Wales – from where some of the stones are thought to originate – in order to cremate and inter their dead at the site. The use of the site for cremations has long been known. Cremains were uncovered in excavations in 1919-26, from at least 5...

IS SHE/HE TRUSTWORTHY?

a day ago
When it comes to predicting who is most likely to act in a trustworthy manner, one of the most important factors is the anticipation of guilt, according to a new study. In the study, researchers identify a trait predictor of trustworthy intentions and behavior. They also provide practical advice for deciding in whom we should place our trust. Among the study’s key findings: a person’s tendency to anticipate feeling guilty, which the researchers call “guilt-proneness,” is the strongest predictor of how trustworthy that person is — more so than a variety of other personality traits (extr...

WHY DEPRESSION AFFECTS SLEEP?

a week ago
Brain areas associated with short-term memory, self and negative emotions are linked with depression which may cause the patients to dwell on bad thoughts and experience poor sleep quality, suggests a study. According to the researchers, about 75 per cent of people with depression report significant levels of sleep disturbance, such as difficulty of falling asleep and short duration of sleep – also known as insomnia. People with insomnia also have a higher risk of developing depression and anxiety than those who sleep normally. “The understanding that we develop here is consistent with areas of the brai...

WINDOWS TO THE SOUL?

If you’re bluffing your way through a game of high-stakes poker, it’s a good idea to avoid shifty, nervous eye movements, which just might give your hand away. But it’s not just during poker that our eyes can betray us. A recent study suggests the way our eyes move actually reveals a scary amount about what we feel inside – to the point where AI can predict somebody’s personality type simply by watching their eyes. “Thanks to our machine-learning approach, we not only validate the role of personality in explaining eye movement in everyday life, but also reveal new eye movement ch...

POSSIBLE ORIGIN OF HUMAN SPEECH

2 weeks ago
Researchers have discovered neural circuits in the brains of rhesus macaque monkeys that could represent a common origin for social communication, including human speech. The findings showed that these circuits are involved in face recognition, facial expression and emotion and they may very well have given rise to our singular capacity for speech. The team, from the Rockefeller University in New York City, used a novel experimental setup to take MRI scans of the brains of monkeys as they watched video clips of other monkeys making communicative facial expressions. When the monkeys in the clips made a friend...

WHY WE DREAM?

2 weeks ago
Dreaming is one of the strangest things that happens to us, and for as long as we have been recording history, we have been puzzling over why our minds are so active while we sleep. Finally, new research claims to have evidence as to what dreaming is all about - and it will probably surprise no one. According to a team from The Swansea University Sleep Lab in the UK, dreaming really does help us process the memories and emotions we experience during our waking lives. This is not a new idea at all. The hypothesis that dreaming was connected to waking life was floated by Sigmund Freud in the early 20th ...

ENGINE OF REVOLUTION

When Sudan the white rhino was put down by his carers earlier this year, it confirmed the extinction of one of the savannah’s most iconic subspecies. Despite decades of effort from conservationists, including a fake Tinder profile for the animal dubbed “the most eligible bachelor in the world”, Sudan proved an unwilling mate and died – the last male of his kind. His daughter and granddaughter remain – but, barring some miraculously successful IVF, it is only a matter of time. The northern white rhino will surely be mourned, as would other stalwarts of picture books, documentaries and sof...

150-MLN-YR-OLD TURTLE FOSSIL DISCOVERED

5 weeks ago
A turtle fossil dating back 150 million years to the Jurassic Period has been found in southwest China’s Chongqing municipality. Farmer Liu Changyu found a turtle-shell-shaped “rock” while in Qijiang district. Liu’s daughter uploaded photos to WeChat, which were spread and spotted by the district’s land resources and housing management bureau, said Xie Xianming, director of the geopark management department of the bureau. Invited by the department, paleontologists from the municipal exploration bureau confirmed it was a fossil of a snake-necked turtle from the Jurassic Period.

TO DETECT HEART DYSFUNCTION

A wireless device was comparable to cardiac MRI in accuracy when detecting heart dysfunction in childhood cancer survivors who were treated with anthracycline chemotherapy, according to a study. Childhood cancer survivors are urged to undergo screening for the detection of heart dysfunction as a result of anthracycline-induced cardiotoxicity. However, screening with echocardiography can be highly variable and limited.  In this study, researchers evaluated the feasibility of using a wireless prototype device to detect heart abnormalities in this population. The protype handheld device, called Vivio, collects pu...

FIRST FOOTPRINTS OF ANIMALS DISCOVERED

6 weeks ago
Researchers have unearthed the nearly 600 million years old fossil footprints of animals, considered to be the earliest record, in China. The study showed that the oldest footprints were left between 551 million and 541 million years ago during the Ediacaran period, about 245 million years before dinosaurs started roaming the Earth.  The team from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences and Virginia Tech in the US discovered two rows of imprints that are arranged in a series or repeated groups in irregular trackways and burrows. These trackways were found in...

NOVEL BLOOD TEST TO IDENTIFY PREMATURE BIRTH

6 weeks ago
Researchers have developed a new blood test for pregnant women that may detect whether their pregnancies will end in premature birth. The technique can also be used to estimate a foetus’s gestational age -- or the mother’s due date -- as reliably as and less expensively than ultrasound, the researchers said. “This work is the result of a fantastic collaboration between researchers around the world,” said co-author Stephen Quake, Professor at the Stanford University in US. The findings, published in the journal Science, suggested that the tests could help reduce problems related to pre...

TINY LAB TO SEARCH FOR ALIEN LIFE ON MARS

7 weeks ago
Scientists have created a toaster oven-sized lab for a Mars rover that will drill beneath the surface of the red planet and look for signs of past or present life. The tiny chemistry lab called the Mars Organic Molecule Analyser (MOMA) is a key instrument on the ExoMars Rover, a joint mission between the European Space Agency and the Russian space agency Roscosmos, with a significant contribution to MOMA from NASA. It will be launched toward the Mars in July 2020. “The ExoMars Rover’s two-meter deep drill will provide MOMA with unique samples that may contain complex organic compounds preserved f...
