Russian Nesting Dolls

The Washington Post had this picture on the cover of my print edition this morning:

Tillerson is the middle doll.

Ok DU Gardeners. How do I keep the squirrels from eating my tulips?

There is plenty of sunflower seed around, but they break off a tulip, take a few bites and then decide they don't taste that great. Any way to keep them away?

Edible batteries use stomach acid as the electrolyte

Batteries of various technologies and form factors get a lot of attention for many reasons. Everyone is looking for a battery with higher energy density by weight and volume, with superior discharge (and even charge) specifications, and low cost. As a result, there's been lots of attention on lithium-ion (Li-ion) chemistry and its many variations, since that seems to offer – at least for the foreseeable future – the greatest potential (pun intended) in meeting those density objectives.

Still, there are applications where unusual chemistries, construction, and form factor are the priorities, more than just an incrementally better Li-ion cell. Consider the work being done by a team lead by Prof. Christopher Bettinger at Carnegie Mellon University. They are developing edible, biocompatible batteries that use non-toxic materials already present in the body, with available liquids such as stomach acid as the electrolyte; see references below (Figure 1). His team has produced cathodes based on melanin, a pigment already in the body, and anodes made of manganese oxide, which is also already present; other versions based on body-friendly materials have also been developed.

The idea is that the electrodes will dissolve harmlessly after use. Most of the resulting batteries, using a variety of soluble cations, had modest voltages (between 0.5 and 0.7 volts); although definitive specifications are hard to find, there was one mention of 5 milliwatts of power for up to 20 hours.

Puppy vs Steps


LOL, at Rubio (who looks like they pulled him out of a bar at last call) & is pretending to be an

expert on something.

Ghosts of American Astronauts

Question: Bannon was removed from the NSC, but he is still a WH advisor right?

He'll go to work at the WH today, helping Trumpy wreck our country, right?

Or am I not understanding his removal?

Add many architects to the various groups...who are distressed by Trumps 2018 budget proposal

Add many architects to the various groups—like environmentalists, the poor, the elderly, and people with disabilities—who are distressed by Donald Trump’s 2018 budget proposal. The president, in a preliminary proposal released Thursday, envisions steep cuts to, or outright elimination of, many programs that architects say benefit their profession. With Trump looking to dramatically scale back domestic discretionary spending across the board, the programs at risk cover a wide array of issues, including housing, transportation, arts, and urbanism.

Here are some of the main programs—as identified by architecture lobbyists and housing advocates—at risk:

(List is below, but the entire article by Ben Adler at the Architectural Review is at

Community Development Block Grants (CDBG)
Affordable housing programs within HUD
Smart growth-friendly programs in HUD and the Department of Transportation (DOT)
National Endowment for the Arts (NEA)
Energy Star

If Congress does pass a budget, rather than following the recent practice of continuing current funding levels in the face of legislative gridlock, few of these proposed cuts would be fully enacted. Even many Republicans would object to some of them. Stephen Glaude, CEO of the Coalition for Nonprofit Housing and Economic Development and a former HUD undersecretary in the first Bush administration, for example, told CNBC that he finds the prospect of ending CDBG “alarming.”

But the real cause for alarm is not the unlikely chance that popular programs like CDBG will actually be zeroed out; rather, it’s the president’s vision to do so.

World's Longest Skyscraper

One World Trade Center is the tallest building in New York City and the United States at 1,776-feet-tall. 217 W. 57th Street will become the tallest skyscraper in New York when it is completed in 2019 at 1,550 feet. One Vanderbilt won’t be much shorter when it reaches its planned height of 1,401 feet in 2020. It’s no secret with all of these planned and under construction skyscrapers in the Big Apple, New York has become infatuated with the intoxicating allure of the supertall.

An architecture firm based in New York and Athens, however, has created a conceptual skyscraper that would surpass all of these towers at 4,000 feet. But there is a catch: the building wouldn’t be 4,000 feet tall, it would be 4,000 feet long.
