"Dynamic psychiatry and psychological intervention in the Arab World are limited and may be due to two major causes: the general low socioeconomic and educational level of the masses and the fact that it is culturally acceptable to conceal one´s thoughts than reveal them," Victor Sanua noted in his contribution to the Reader "The Spiritual Side of Psychology at Century´s End". "The Arabic word for reveal is ´kashafa´ which means also to remove the veil, a woman´s proper covering.

Einstein's theory of general relativity upended humanity's understanding of the universe more than a century ago, and since then, scientists have discovered that the steady march of time is anything but steady. Among the haunting implications of general relativity is that time passes more quickly at the top of every staircase in the world than it does at the bottom.

This mind-bending phenomenon happens because the closer an object is to Earth, the stronger the impacts of gravity are. And because general relativity describes gravity as the warping of space and time, time itself travels more slowly at higher altitudes and greater distances from Earth, where gravity has less of an effect.

The 11,000-year-old carved relief, found in Turkey, is the oldest narrative carving on record. An 11,000-year-old rock-cut relief in southeastern Turkey featuring menacing animals and two men, one of whom is holding his genitalia, is the oldest narrative scene on record, a new study suggests. Archaeologists discovered the curious carvings on built-in benches within a Neolithic (or New Stone Age) building in the Urfa region. Measuring roughly 2.5 to 3 feet (0.7 to 0.9 meter) tall and 12 feet (3.7 m) long, the newly discovered rock-cut relief showcases two leopards, a bull and the two men — one grasping his phallus and the other holding a rattle or snake.

Psychologists in Austria develop and examine a measure instrument of personality based on quantitative text analysis. They use linguistic markers that have been shown to be related to the Big-Five personality traits and define a linguistic model of personality based on these findings.

Patients with nasopharyngeal cancer are often treated with drugs that activate their immune system against the tumor. Until now, it was feared that vaccination against Covid-19 could reduce the success of cancer treatment or cause severe side effects. A recent study by the Universities of Bonn and Shanxi in the People's Republic of China now gives the all-clear in this regard. According to the study, the cancer drugs actually worked better after vaccination with the Chinese vaccine SinoVac than in unvaccinated patients. The results are published as a "Letter to the editor" in the journal Annals of Oncology, but are already available online.

Traces of ancient viruses are littered throughout the human genome, embedded within the DNA's structure. Scientists already knew that some of these viral artifacts can "activate" in cancer cells and potentially contribute to the disease's progression — but now, a new study reveals that the viruses are active in dozens of healthy tissues, too.

RALEIGH, N.C. (Ivanhoe Newswire) – Surgeons at Duke University Hospital performed the world’s first combination heart transplant and thymus tissue implantation and now, a year later, their 18-month-old patient is a growing, thriving medical miracle.

After dominating the Earth for more than 160 million years, the dinosaurs finally met their doom thanks to a visitor from space. Around 66 million years ago, an asteroid measuring at least 6 miles (10 kilometers) across dealt the dinosaurs' world a devastating blow, triggering earthquakes, tsunamis, volcanic eruptions and climate catastrophes that soon rendered 75% of all living creatures extinct.

But, through all this, Earth itself remained.

Does this mean our planet is immune to an asteroid Armageddon? If the dreaded dino-killing asteroid wasn't enough to end the world, then what would it take? Could a space rock actually destroy the entire Earth — and how big would it have to be?

In 1881, archaeologists unearthed the skull of a human buried inside a cave in Mladeč, a village in what is now the Czech Republic. At the time, researchers dated the skull to about 31,000 years ago and classified the individual as male.

But they were wrong about the Stone Age person's sex, a new study finds.

The earliest evidence of opium usage in the ancient world has been discovered at a burial site in central Israel that dates to around 14th century B.C., during the Late Bronze Age.
