Researchers have deciphered an ancient Egyptian handbook, revealing a series of invocations and spells. "It is a complete 20-page parchment codex, containing the handbook of a ritual practitioner," write Malcolm Choat and Iain Gardner, who are professors in Australia at Macquarie University and the University of Sydney, respectively, in their book, "A Coptic Handbook of Ritual Power" (Brepols, 2014).

The demand for global trade is driving huge growth in ship traffic in the world's oceans, with four times as many ships at sea now than in 1992, a new study reports. The study also found evidence of illegal fishing in protected marine areas, such as ships plying waters around the Kerguelen Islands Marine Reserve in the Southern Indian Ocean, said study author Jean Tournadre, an oceanographer at IFREMER, the French Institute for Marine Research in Plouzane. "I was surprised to see that in 20 years, the growth is almost fourfold, or almost four times larger," Tournadre said. The biggest increase in ship traffic between 1992 and 2012 was along popular shipping lanes in the Indian Ocean and the Chinese seas.

Using marijuana daily for four years or longer may be related to certain changes in the brain, according to new research. The investigators found that the people who had been smoking marijuana daily for at least four years had a smaller volume of gray matter in a region called the orbitofrontal cortex, which is commonly associated with addiction. "We found that there … not only is a change in structure, but there also tends to be a change reflected in the connectivity," said study author Francesca Filbey, an associate professor in the School of Behavioral and Brain Sciences at the University of Texas at Dallas. The lost brain volume could explain the increased connectivity found in marijuana users' brains, Filbey told Live Science.

The 9.5-foot-tall (3-meter) Gemini spacecraft, which was part of RR Auction's week-long space sale that ended on Thursday (Nov. 20), narrowly escaped officers giving it a ticket when it was parked in a loading zone outside the Boston auction house's salesroom on Sunday. "I had to talk my way out of a parking ticket!" wrote Bobby Livingston, RR Auction's executive vice president, in an e-mail to collectSPACE.com. Parking citations aside, the two-ton artifact is an example of a "boilerplate" - metal, none-functioning capsules built to the same size and shape as the spacecraft they were designed to test. According to Livingston, this particular Gemini boilerplate was originally used for tests supporting the recovery of the Gemini capsules after they returned from orbit to a splash down in the ocean.

G. Jogesh Babu is director of the Center for Astrostatistics at Penn State, and Eric Feigelson is the center's associate director and professor of astronomy and astrophysics at Penn State. After a century hiatus, astronomy and statistics recently reconnected, giving rise to the new field of astrostatistics. NASA's Kepler mission has detected several thousand planets orbiting other stars, but it was through statistics that astronomers inferred that most stars have planetary systems and hundreds of millions of Earth-like planets probably exist in the galaxy. Such insights followed a long gap in the relationship between astrostatistics - a term coined by us in our book of the same title published in 1996 - and the broader field of astronomy.

By Kate Kelland LONDON (Reuters) - - A banking culture that implicitly puts financial gain above all else fuels greed and dishonesty and makes bankers more likely to cheat, according to the findings of a scientific study. Researchers in Switzerland studied bank workers and other professionals in experiments in which they won more money if they cheated, and found that bankers were more dishonest when they were made particularly aware of their professional role. ...

Small volcanic eruptions account for part of the global warming slowdown since 2000, a new study suggests. Until now, the climate impacts of small volcanic blasts were overlooked because their planet-cooling particles cluster below the reach of satellites, scientists reported Oct. 31 in the journal Geophysical Research Letters. The stratosphere is the second layer of Earth's atmosphere, above the one in which humans live (the troposphere). Closer to the polar regions, the boundary drops to about 6 miles (10 km), said lead study author David Ridley, an atmospheric scientist at MIT.

JOHANNESBURG (Reuters) - A tiny shrimp equipped with large, candy-striped eyes to ward off predators has been discovered in South African waters, the University of Cape Town said on Friday. The 10-15 mm-long crustacean has been christened the "star-gazer mysid" as its eyes seem to gaze permanently upwards. Similar to insects' eyes, they each look in a different direction. "The vivid ringed patterns are thought to be there to make the eyes appear to belong to a much bigger creature, and hence to scare off predators," the university said. ...

By Will Dunham WASHINGTON (Reuters) - The Tibetan Plateau, the harsh Asian domain known as the 'roof of the world,' would not seem an ideal place for people to call home thanks to its extreme altitude, frigid temperatures, relentless winds and low-oxygen conditions. When people did succeed in colonizing this remote land, it was only after they discovered how to feed themselves year-round with cold-hardy crops like barley brought to the region from far away, scientists said on Thursday. ...

By Will Dunham WASHINGTON (Reuters) - A class of drugs used for three decades by people infected with the virus that causes AIDS may be effective in treating a leading cause of blindness among the elderly. HIV drugs called nucleoside reverse transcriptase inhibitors (NRTIs), including AZT and three others, blocked age-related macular degeneration in mice and worked well in experiments involving human retinal cells in the laboratory, researchers said on Thursday. In HIV-infected people, NRTIs block an enzyme the virus uses to create more copies of itself. ...

The idea that an infinite number of parallel worlds could exist alongside our own is hard to wrap the mind around, but a version of this so-called Many Worlds theory could provide an answer to the controversial idea of quantum mechanics and its many different interpretations. Bill Poirier, a professor of physics at Texas Tech University in Lubbock, proposed a theory that not only assumes parallel worlds exist, but also says their interaction can explain all the quantum mechanics "weirdness" in the observable universe. Poirier first published the idea four years ago, but other physicists have recently started building on the idea and have demonstrated that it is mathematically possible. Quantum mechanics is the branch of physics that describes the rules that govern the universe on the microscopic scale.

By Sophie Knight and Kaori Kaneko TOKYO (Reuters) - Neurosurgeon Tetsuya Goto had just begun testing a robot to perform brain surgery when he discovered Japan was moving to tighten regulations that would shut down his seven-year project. Over the next dozen years he watched in frustration as the da Vinci, a rival endoscopic robot that U.S. regulators had already approved, became a commercial success while his and other Japanese prototypes languished in laboratories. ...

With the goal of landing the first Israeli spacecraft on the moon, nonprofit SpaceIL is competing for the Google Lunar XPrize: a modern race to the moon. First, instead of developing a rover to drive 500 m like most other teams, SpaceIL engineers are pursuing a "hop" - using the spacecraft's propulsion system first to land, and second to take off again and land 500 m away. Second, we are using the mission not only to stimulate technological advancement, but also to investigate the lunar magnetic field: To that aim, SpaceIL will be carrying a scientific experiment that will advance humanity's shared understanding of the moon. Although magnetized rocks were discovered decades ago, and astronauts returned some samples to Earth for research, the origin of the magnetic field presents an enigma - and an opportunity.

NASA's New Horizons probe is about to wake up from a long slumber and get ready for its highly anticipated Pluto flyby next summer. New Horizons is scheduled to emerge from a 99-day hibernation on Dec. 6, then gear up for a six-month Pluto encounter that peaks with the first-ever close flyby of the mysterious dwarf planet on July 14, 2015. "New Horizons is healthy and cruising quietly through deep space, nearly 3 billion miles [4.8 billion kilometers] from home, but its rest is nearly over," Alice Bowman, New Horizons mission operations manager at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, said in a statement. New Horizons launched in January 2006.
