Scientific advances in materials science and image analysis enable the work of renovation tackle more ambitious challenges. A recent example of this is the Hudson Theatre in Manhattan.


One of Broadway’s oldest surviving theatres, first opened 114 years ago, has been renovated and reopened earlier this year –

05HUDSON3-jumbo-v2.jpg— with Jake Gyllenhaal in the revival of “Sunday in the Park With George”. It becomes Broadway’s 41st and newest playhouse, 114 years after it became one of Broadway’s first. Then, it opened with a production of “Cousin Kate” starring Ethel Barrymore.


The theater was built by Henry B. Harris, above left, who ran it until 1912, when he perished on the Titanic. His wife, Renée, also above, survived and returned to New York to operate the theater. She became one of Broadway’s first female producers but she lost it to foreclosure in the Depression.


Located on 44th Street just east of Broadway, the ornate theater has led a life as various as Manhattan itself, with stints as a TV studio (1950s), a reborn theater and then a porn palace (’60s), a rock venue (’80s), and, for the last 20 years, an event space for Millennium Hotels.


After the renovation by the Ambassador Theatre Group of Britain the Hudson is ready to be a showplace again and one of the few new theatres on  Broadway.



The “Plastic Show” at the Almine Rech Gallery in London is by Melissa Castro Duarte.


It brings together works by DeWain Valentine and four of his contemporaries — Mary Corse, Robert Irwin, Craig Kauffman and John McCracken — who were all experimenting with newly available materials in Venice and Santa Monica in the 1960s.

Valentine’s acrylic sculptures suggest the air is “becoming a substance”: They’re vast glossy blocks, columns, discs and lozenges that change color as you move around them and gaze in and through them. “All my work is really about the sky and the sea,” he says.


The high sheen of his sculptures comes from buffing and lacquering, techniques used in his parents’ garage. Works in the show by John McCracken, by contrast,  are constructed from plywood and fiberglass with a glossy shell of polyester resin, just like a surfboard.

Polyester is a synthetic polymer made of purified terephthalic acid (PTA) or its dimethyl ester dimethyl terephthalate (DMT) and monoethylene glycol(MEG).

PTA is 1,4 benzenedicarboxylic acid: C6H4(COOH)2, mol. weight: 166.13

DMT is 1,4 benzenedicarboxylic acid: C6H4(COOCH3)2, mol. weight: 194.19
MEG is 1,2 ethanediol: C2H6O2 , mol. weight: 62.07

Books Smell

On March 4th the New York Times asked whether books smell the same. The question was inspired by Vladimir Nabokov who wrote:

“Nothing revives the past so completely as a smell that was once associated with it.”

For many people, the smell of books, in particular, is one of memory’s most powerful messengers, especially as the printed page gives way to the digital.

Over the past year, a Columbia University preservation expert and a curator at the Morgan Library & Museum in Manhattan have been engaged in an unusual poetic-scientific experiment in the little-visited olfactory wing of history, trying to pin down the powerful connection between smell and memory — in this case, collective memory.

Jorge Otero-Pailos, director and professor of historic preservation at Columbia University, smells a bookcase in Pierpont Morgan’s study at the Morgan Library & Museum.

Thousands of molecules will be categorized to determine which of them constitutes the smell profile of objects and surfaces from the Morgan Library.


Big Balls

Polyhedra with up to 144 components can form by self-assembly (Nature, 22 December 2016, D. Fujita et al).  Familiar examples are the outline structures of golf balls and footballs.

All that’s needed is a range of ligands – ions that bind to a central metal atom to form a coordination complex:


The resulting ‘Goldberg Polyhedra’ are complex shells that protect viruses and cellular structures.      th-3.jpeg

The organic-metallic cages encapsulate proteins and other molecules, and may retain particular enzymes within particular structures.


Water, Water Everywhere

Why is there so much water on and around our planet, and where did it come from?

One idea is that it originated from ice specks floating in a cosmic cloud more than 4.6 billion years ago. Such interstellar water is millions of years older than the solar system itself. This water survived the solar system’s chaotic creation and came to Earth.


(Bill Saxton, NSF National Radio Astronomy Observatory)

Much of the heavy water formed in the interstellar cloud and then traveled across the solar system.

About one atom in 6420 of hydrogen has a neutron and is called deuterium. It accounts for approximately 0.0156% of all the naturally occurring hydrogen in the oceans. The more common isotope (hydrogen-1 or protium) accounts for more than 99.98%.

Deuterium-rich water is found on other planets and moons, even here on Earth, but researchers are not sure where it came from.

A recently constructed computer model shows how such old ice molecules could have survived the sun’s violent radiation blasts, and gone on to the present planet Earth and its neighbours.


Water is strongly associated with this sculpture called Barbora, by the American artist Vladas Vildžiūnas, presently found in Thornton Park, Vancouver.  The original concept was a lady walking in a park in solitude with breezes adding movement to her garments. Others see it as the movement of water in similar free space.

Track Repairs

Old railway lines easily break down and need regular maintenance. Without that, weeds and trees grow on the line. Trains crash. Similarly, DNA is unstable and can break up. Now, it appears that some of these mutations can be repaired.

The 2015 Nobel Prize in Chemistry has been awarded to Tomas Lindahl and Paul Modrich and Aziz Sancar for discoveries in DNA repair. They aim to put right some familiar mutations.
Their work uncovered mechanisms used by cells to repair damaged DNA – a fundamental process in living cells and important in cancer. Tomas Lindahl is from the UK’s Francis Crick Institute.

Damaged sites in the chromosomal DNA can result in cell death or cancer, but may be corrected by DNA repair enzymes prior to phenotypic expression.

The prize-winners investigated properties of several nuclear enzymes that remove harmful lesions or local aberrant structures from DNA. The absence of such DNA repair factors may result in an increased frequency of malignant transformation, or in some cases may be detected as immunological deficiencies.
