Which structures are they going to form and how will they be oriented? Would mixing allow a finetuning of the thin film structures for special applications, e.g. in nanolithography, without resorting to substrate prestructuring? The team investigated blends of long and short PS-b-P2VP (polystyrene-b-Poly(2-vinylpyridine) with a length ratio of short to long chains of 1:6.9. Each of these polymers microphase separate into lamellar structures by itself, albeit with different period. Blends should feature coexisting domains of thin and thick AB lamellae [2,3].

Visualizing the shape of the receptor has also allowed them to make a second groundbreaking discovery: They observed that five painkiller molecules they tested did not bind the receptor at the place they expected, which could explain why these painkillers lack efficacy in human patients.

This discovery, published Dec. 9, 2016, in the journal eLife, lays the foundations to create targeted and effective molecules to manage chronic pain.

As a reminder, the changes to the storage ring will:

This was the year his “Blue Period” began, and remains a time of great interest to art historians and enthusiasts alike. Technical analysis of paintings made during this period are one approach to finding clues into as-yet understood aspects of Picasso’s experience and process. The recent discovery of a buried portrait below one of his first blue period paintings, “The Blue Room,” (The Phillips Collection, 1600 21st St NW, Washington DC) offers an example of two paintings, each by Picasso, that represent snapshots of this transition.

For Chaney Miller ’14 CEE it was freshman year. “I got to Cornell without taking a physics class before,” says Miller, who was admitted to Cornell in the College of Arts & Sciences. But before arriving on campus, she enrolled in engineering courses instead. When she changed paths to transfer into civil engineering, she had to take several physics courses with no foundation in the subject. “I felt like giving up something like eight times that semester,” says Miller. “But I am hard-headed and I saw it as a challenge so I stuck with it.”

These new hutches are prototypes and a head start for the CHESS-U upgrade planned for summer 2018. The complete structure was pre-fabricated at ADC Inc.

This past semester an enthusiastic team of graduate students ignited public interest in accelerators and light sources by creating and presenting interactive exhibits that demystify synchrotron science.

Graduating a year early from Lansing High School, just outside of Ithaca, Campello contacted Cornell physics professor Jim Alexander, who connected him to staff at the Cornell High Energy Synchrotron Source (CHESS). They gave him a tour, and Campello signed on for a monthlong internship there while still in high school.

Understanding how grape buds respond to subzero temperatures is of paramount concern to vineyard managers in New York and other northerly grape-producing states. Some of the more popular varieties used in the wine and juice industries can survive temperatures far below the freezing point of water. By a process known as supercooling, cellular mechanisms within the bud maintain water in liquid state down to around minus 4 to minus 30 degrees Fahrenheit, depending on the species.

Teachers from different science backgrounds, including physics, biology and chemistry attended our Spring Workshop where Xraise hosted presentations from researchers and presented one of the Lending Library activities called “Water Analogy to Electrical Circuits”.
