Wormhole simulated in quantum computer could bolster theory that the universe is a hologram

Physicists have used a quantum computer to simulate the first-ever holographic wormhole and transport information through it.

The "baby" wormhole, created on Google's Sycamore 2 quantum computer was not created with gravity, but through quantum entanglement — the linking of two particles such that measuring one instantaneously affects the other.

Archaeologists in Egypt have uncovered the remains of several mummies with tongues made of gold in an ancient cemetery near Quesna, a city located about 35 miles (56 kilometers) north of Cairo, according to Egypt's Ministry of Tourism and Antiquities.

Some of the mummies were buried in wooden coffins with grave goods that included necklaces, pottery, and gold artifacts in the shape of lotus flowers and beetles known as scarabs, the ministry reported in a statement posted to Facebook on Nov. 24.

Why are paper cuts so painful?

You're engrossed in a mystery novel, but in your excitement to discover "whodunit," you turn the page too quickly and slice open the skin of your pointer finger. A jolt of pain shoots through the paper cut and you gasp, not because you've just learned that the butler did it, but because the teeny-tiny cut hurts so badly.

Why are paper cuts so painful? It's a combination of our hands being incredibly sensitive to pain and papers' edges being surprisingly jagged.

Pregnancy causes dramatic changes in the brain, study confirms

(National Institute of Mental Health, National Institutes of Health)

Pregnancy leads to striking changes in the brain, including alterations in gray matter and regions involved in self-perception, according to a new study.

The findings suggest that these neurological changes may promote bonding between mother and baby and could play a role in the identity shift that many women feel when they become new mothers, the researchers said.

Woman gets rare case of 'toxic squash syndrome' after drinking bitter gourd juice

Minutes after drinking a bitter juice made from a pureed gourd, a woman went into shock, a life-threatening condition where blood flow in the body plummets and organs can be injured from lack of oxygen.

She told emergency room doctors that she'd consumed the same type of gourd daily for many years, but on this occasion, "it tasted abnormally bitter." That vile taste may explain why she developed "toxic squash syndrome," a rare condition that arises from eating toxic substances sometimes found in squashes and gourds.

14th-century Ashkenazi Jews had more genetic diversity than their descendants do today

A rare look at the genetics of Ashkenazi Jews who lived in medieval Germany reveals this group had more genetic diversity 600 years ago than today, and reaffirms a recent finding that a "genetic bottleneck" in the Ashkenazi population occurred before the Middle Ages.

Religious laws usually prohibit any such research into the Jewish dead, but scientists worked with the region's modern Jewish community to find a workaround: They studied the centuries-old DNA in detached teeth unearthed in the burials recovered from excavations in Erfurt, a town in central Germany, according to a study published Nov. 30 in the journal Cell.
