Mummy of Egyptian Noblewoman Found.

The 3,800-year-old mummy belonged to Lady Sattjeni, a leading figure from the Middle Kingdom.

Spanish archaeologists have discovered the 3,800-year-old mummy of Lady Sattjeni, a leading figure from the Middle Kingdom, authorities at the Ministry of Antiquities announced on Tuesday.
Sattjeni’s family was just below pharaoh Amenemhat III (1800-1775 B.C.) in the hierarchy of Elephantine, an island in the center of the Nile at Aswan. Her sons Heqaib III and Ameny-Seneb ruled there at the end of the Twelfth Dynasty.
According to Mahmoud Afify, head of the Ancient Egyptian archaeology division the Ministry of Antiquities, the discovery is historic as it helps reconstruct the family tree of the governors of Elephantine.
Sattjeni’s mummy was found in the necropolis of Qubbet el-Hawa, near the modern city of Aswan, by a team of Jaén University, Spain, led by Egyptologist Alejandro Jiménez-Serrano.
“The body was originally wrapped in linen and deposited in two wooden coffins made of Lebanon cedar,” Nasr Salama, general director of Aswan and Nubia areas, said.
Over Sattjeni’s face, the archaeologists also found remains of her cartonnage mask.
“The inner coffin was in extremely good condition. This will even allow us to date the year in which the tree was cut,” the ministry said in a statement.
Jiménez explained that Lady Sattjeni was the daughter of the nomarch Sarenput II, the owner of the finest and largest tomb at Qubbet el-Hawa. After the death of all the male members of her family, she held the dynastic rights in the government of Elephantine.
The Spanish researchers, who have been digging in the necropolis since 2008, had previously brought to light several other burials, including that of Sattjeni’s eldest son Heqaib III.

CAN ADDICTION BE CURED WITH VACCINES?.

The goal of antiaddiction vaccines is to prevent addictive molecules from reaching the brain, where they produce their effects and can create chemical dependencies. Vaccines can accomplish this task, in theory, by generating antibodies—proteins produced by the immune system—that bind to addictive particles and essentially stop them in their tracks. But challenges remain.
Among them, addictive molecules are often too small to be spotted by the human immune system. Thus, they can circulate in the body undetected. Researchers have developed two basic strategies for overcoming this problem. One invokes so-called active immunity by tethering an addictive molecule to a larger molecule, such as the proteins that encase a common cold virus. This viral shell does not make people sick but does prompt the immune system to produce high levels of antibodies against it and whatever is attached to it. In our laboratory, we have tested this method in animal models and successfully blocked chemical forms of cocaine or nicotine from reaching the brain.
Another approach researchers are testing generates what is known as passive immunity against addictive molecules in the body. They have cultured monoclonal antibodies that can bind selectively to addictive molecules. The hurdle with this particular method is that monoclonal antibodies are expensive to produce and need to be administrated frequently to be effective.
We have tried to circumvent these issues by genetically modifying the liver of mice to produce and secrete sufficient quantities of antiaddictive monoclonal antibodies, but that work is still in its early stages. If successful, though, addiction vaccines would be a valuable aid to help addicts quit.

ExxonMobil Faces Showdown with Shareholders over Climate Change.

DALLAS—For years, Exxon Mobil Corp. has held its annual meeting here in a cavernous symphony hall downtown, where shareholders today will discuss the company’s future and cast their ballots on more than a dozen proposals.
But while the location hasn’t changed, the mood outside Exxon has shifted dramatically—particularly on global warming. The company is grappling with low oil prices and investigations from attorneys general into allegations that it downplayed the economic threat of climate change—and today will face a raft of resolutions demanding that it acknowledge and tackle rising temperatures.
“Folks perceive them to be a leader in the fight against addressing climate change,” said Danielle Fugere, president of the As You Sow nonprofit group, one of several that submitted resolutions to Exxon.
“They are the face of the anti-climate movement. And I think that’s why we see so many resolutions against Exxon,” Fugere said.
“They’re such an easy target, but they make themselves an easy target,” added W. Andrew Mims of the Sustainability Group, a division within Boston-based investment house Loring, Wolcott & Coolidge.
Of the 14 resolutions before Exxon, eight deal with global warming or environmental controversies, such as hydraulic fracturing. They prod the oil giant to acknowledge that insurgent energy sources and climate regulations—namely those agreed to by most of the world’s nations under the Paris Agreement—threaten its existence.
Boards of directors typically oppose shareholder resolutions, which rarely pass without support from the board. Exxon opposes all the resolutions slated to be voted on today and petitioned the Securities and Exchange Commission to keep one climate resolution off the ballot.
As of last night, environmental demonstrators protesting Exxon’s track record on climate change and calling for the sale of company stock were preparing for a rally this morning outside the symphony hall. Nearby they made room for an ice block to be carved with the phrase “#ExxonKnew,” a reference to the revelation that company scientists warned Exxon management of climate change risks decades ago.
Exxon spokesman Alan Jeffers said in an interview that there are more resolutions than are typical for annual meetings.
He said Exxon addressed questions from shareholders about climate policies, their possible effect on business, changes in energy demand and “carbon asset risk” in a report issued in 2014.
“The risk of climate change is clear and the risk warrants action,” reads one of Exxon’s statements on climate change. “We have the same concerns as people everywhere—and that is how to provide the world with the energy it needs while reducing greenhouse gas emissions.”

PAST MAY BE PROLOGUE, BUT SHAREHOLDERS ARE OPTIMISTIC

In the wake of the international accord on climate change struck in Paris in December, the number of climate-related shareholder resolutions worldwide hit an all-time high.
The strategy behind such advocacy is simple: to use one’s financial stake within a company to raise an issue and lobby for changes.
Though resolutions are typically nonbinding, the variety of proposals filed in a given year and the amount of support they receive provide good indications of investor sentiment.
Shareholders at BP PLC, Royal Dutch Shell PLC and Statoil ASA last year approved resolutions to disclose how the companies view the financial risks associated with climate change by nearly unanimous votes. Glencore PLC, the international commodity and coal firm, passed a comparable measure Thursday with 98 percent support.
“They’re really just sensible risk management,” Edward Mason, head of responsible investment at the Church Commissioners for England, said of those past policies.
For its part, Exxon projects oil demand worldwide will continue to grow, expanding by more than 13 percent from today’s figures by 2040.
Yet one of the International Energy Agency’s forecasts—a circumstance in which governments cap greenhouse gas emissions—estimates oil demand could fall by more than 20 percent by 2040.
While Exxon has never passed a resolution related to climate change, shareholders worried about global warming are optimistic that today will be different.
“The world is changing; the world is starting to adapt,” said Andrew Logan of Ceres, the sustainable investment advocacy group. What investors are asking for, he said, “seems astonishingly modest.”

CALPERS TRIES TO WIELD ITS $1B IN INFLUENCE

Among today’s eight environmental resolutions are several asking Exxon to publish reports with long-term planning and outlooks, omitting commercially sensitive information.
To meet the goals reached in Paris to limit warming to no more than 2 degrees Celsius beyond preindustrial temperatures, carbon fuels will have to remain untapped, said Anne Simpson of the California Public Employees’ Retirement System (CalPERS), which invests about $300 billion.
“You can’t burn everything that’s on these companies’ balance sheets,” Simpson said.
As the biggest U.S public pension fund, CalPERS owns about $1 billion in Exxon stock and is backing a resolution that would compel the company to commission a report on the long-term “impacts of public climate change policies” on its business.
CalPERS is also backing a proposal for “proxy access”—authored by New York City Comptroller Scott Stringer, the fiduciary for the city’s five public pension funds, worth more than $150 billion—that would allow shareholders to nominate candidates to the Exxon board.
Stringer’s office has targeted dozens of fossil fuel companies this year and last with this strategy, specifically citing climate concerns.
“Investors would benefit from an assessment of ExxonMobil’s oil and gas reserves under a scenario consistent with the global emissions reduction target defined in the Paris Agreement,” Simpson and Stringer told Exxon shareholders in a letter.
Other climate resolutions on the table call for Exxon to have a climate change expert on its board and to finalize a policy “acknowledging the imperative to limit global average temperature increases to 2 degrees above pre-industrial levels.”
In an attempt to encourage markets to value oil suppliers like Exxon and “think outside the barrel,” Fugere submitted a proposal that would require the oil giant to report its energy reserves in units of energy—British thermal units—instead of barrels of crude.
“They have actually been at least slightly supportive of the concept,” said Fugere, who called that reaction surprising.

PLEASE LEAVE YOUR NAME WITH THE SECRETARY

Investors who have filed resolutions with Exxon for years described the oil giant as a savvy, well-run company whose leaders understand the financial and reputational risks of climate change and who are willing to meet to discuss shareholder proposals but often disagree.
They also describe Exxon as a difficult but rewarding hurdle—a company whose support of climate policies could trigger broader acceptance and awareness throughout the energy industry and among investors of the financial risks that climate change poses. The challenge and the potential payoff, they said, are what motivates them to turn in resolutions year after year.
Tim Smith is a director of shareholder engagement at Walden Asset Management, a Boston investment firm, who has been working on shareholder advocacy since the 1970s. He said that in the last few years, Exxon officials have met for the better part of a day in New York with 25 to 30 shareholders to talk about climate issues. “Not just a dog-and-pony show,” he said.
But four stockholders said Exxon does not allow them to talk with board members directly, a practice they find frustrating.
“That’s not normal. Usually you can have access in some way to the board,” said Mike Crosby, a Franciscan friar from Milwaukee who began his corporate engagement career in 1973 at the Interfaith Center on Corporate Responsibility (ICCR).
Sister Patricia Daly, a nun from New Jersey who is famous within shareholder advocacy circles and is a colleague of Crosby’s, agreed.
“They get really angry if we attempt to communicate with a board member outside the corporate secretaries,” Daly said.
Jeffers said the board set that policy. “It’s inaccurate to say the company has a policy,” he said.

A PRIEST AND A NUN WALK INTO A SHAREHOLDERS MEETING

The shareholder advocacy world is small and traces much of its history back to groups like the ICCR, a group of several hundred religious institutions that together oversee $100 billion in assets.
While they each direct small sums of company stocks compared to Wall Street firms or mainstream asset managers, Father Crosby, Sister Daly and Smith are widely known by name and history.
The trio are perennials at corporate meetings, each with decades of experience filing proposals and working on matters of the environment, human trafficking, health, water use and other subjects.
“We regularly engage with them and look forward to that,” Exxon’s Jeffers said of Crosby and Daly.
“She’s been a visionary leader in identifying issues of social and environmental concern,” Ford Motor Co. Executive Chairman Bill Ford said of Daly in 2014. They worked together on environmental sustainability at the automaker.
“Pat is my candidate for sainthood,” said Stephen Viederman, a shareholder engagement expert in New York.
“Pat was identified as an RN at one point. A ‘radical nun,’” he said, before chiming in again: “Oh! Father Mike is great. He, too, could be saint.”

Stone henge: Easier Done Than Said


How hard could it have been for prehistoric Britons to move stones the size of dump trucks?
How did prehistoric Britons manage to move Stonehenge’s stones? Each rock weighed an average of 25 tons and stood as tall as 30 feet, and the first tractor was still five millennia away, so clearly they must have endured great pains to build the monument, right?
Much of the mystery around the site comes from the questions of how Stonehenge was built and why. A recent experiment by archaeologists at University College London provides a hint to that first part anyway.
As back-breaking a task as building a monument of dump truck-sized stones without the aid of modern machinery might seem, the demonstration held in London’s Gordon Square suggests it wasn’t that difficult at all.
Last week, University College London doctoral candidate Barney Harris put out a call for volunteers to see how many people it would take to pull a stone about half the size as the smallest rock at Stonehenge, which is about one metric ton. Harris anticipated it would take a team of at least 15 people to move the stone, and as many as 40 to 50 to lift it.
Instead, 10 people were able to get the stone going at a rate of roughly 10 feet (3 meters) every five seconds, or around one mile (1.6 kilometers) per hour. A team twice the size would be able to move a small piece of Stonehenge.
Devoting the kind of human capital needed for what may appear to be a frivolous effort for a Neolithic society isn’t all that far-fetched considering settlements in the area at the time numbered in the thousands, so there were plenty of other members of the society to carry on with the more life-sustaining activities, such as farming, hunting or child-rearing
Made of rope, a wooden track and a sycamore sled, the design of the rig used in the experiment mirrors others found throughout the ancient world. “We know that pre-industrialized societies like the Maram Naga in India still use this kind of sledge to construct huge stone monuments,” Harris told The Telegraph. “And similar y-shaped sleighs have been found dating back to 2000 B.C. in Japan which we know were used to move megaliths.”
Recreating even at a small scale how the rocks used at Stonehenge were transported can provide researchers an estimate of how long it took to complete the entire site.
Beginning around 5,000 years ago, the first stones were lain at Stonehenge. The monument was built in two phases with two different kinds of stones. The largest stones are called sarsens, a local sandstone, placed around 2400 B.C. The circle of rocks at the center, known as bluestones, were erected 500 years earlier, around 2900 B.C.
Neolithic people quarried the slabs of bluestone in Preseli hills in Pembrokeshire, Wales. The builders then transported the rocks 140 miles (225 kilometers), through steep and uneven terrain, to the site of the monument in Wiltshire, England, reported a separate University College London study last year. The system devised in the most recent experiment works well over these rough patches and without the aid of livestock.
Knowing how ancient builders could have constructed Stonehenge does take a little mystery out of the site. But if nothing else, Stonehenge still stands as a marvel of ancient ingenuity, erected by people smart enough to make the effort as easy on themselves as possible at the time.
