‘Lost Golden City’ found in Luxor
Egypt’s best-known archaeologist, Zahi Hawass, announced today that the long-lost ruins of a 3,000-year-old city have been found in Luxor. The sprawling settlement dates to the reign of Amenhotep III and his son, Akhenaten. Egypt’s Ministry of Tourism and Antiquities says it continued to be used by Tutankhamun and his successor, King Ay.
The city was at one time called “The Rise of Aten,” reflecting the religious shift brought about by Akhenaten. Today it’s being called the “Lost Golden City.” During the past seven months of excavation, several neighborhoods have been uncovered, but the administrative and residential district hasn’t yet been brought forth from the sands. “The discovery of this lost city is the second most important archaeological discovery since the tomb of Tutankhamun,” said Betsy Bryan, an Egyptologist at Johns Hopkins University.

Muon anomaly sparks deep questions
Anomalous results from a Fermilab experiment have added to the suspicion that scientists have finally found a flaw in one of their most successful theories, the Standard Model of particle physics. The anomalies have to do with the strength of the magnetic field for a weightier cousin of the electron, known as the muon. Data from Fermilab’s Muon g-2 experiment supported previous findings from Brookhaven National Laboratory that the muon’s magnetism is ever-so-slightly stronger than predicted by the Standard Model — just 2.5 parts per billion stronger.
If the results hold up, physicists might have to consider far-out explanations — for example, the existence of scads of particles that haven’t yet been detected, or a totally new take on the foundations of physics. But the findings will require further confirmation. Grand discoveries, like 2012’s detection of the Higgs boson, typically have to be confirmed to a confidence level of 5-sigma. Now the muon findings have hit 4.2-sigma — which doubters would say is still substandard.

Elon Musk touts mind control
Neuralink, the brain-implant venture funded by tech billionaire Elon Musk, is showing off an AI system that lets a macaque monkey play a game of Pong with its mind alone. Researchers monitored the monkey’s neural impulses as it operated a joystick to play the game, and then correlated the firing patterns of the neurons with the gameplay. Eventually, the brain-monitoring system eliminated the need for the monkey to use the joystick at all.
In a Twitter exchange, Musk said human trials of the mind-reading system would begin, “hopefully, later this year.” He said Neuralink’s first brain-implant product would enable someone with paralysis to use a smartphone with their mind faster than someone using thumbs. “Later versions will be able to shunt signals from Neuralinks in brain to Neuralinks in body motor/sensory neuron clusters, thus enabling, for example, paraplegics to walk again,” Musk tweeted.
