Million frames per second infrared imaging system

An infrared imaging system has been developed for measuring the temperature increase during the dynamic deformation of materials. The system consists of an 838 HgCdTe focal plane array, each with its own preamplifier. Outputs from the 64 detector/preamplifiers are digitized using a row-parallel scheme. In this approach, all 64 signals are simultaneously acquired and held using a bank of track a...

More than half a million California adults seriously thought about suicide in the past year.

In 2009, nearly 2.4 million adults in California reported having seriously thought about suicide during their lifetimes. Among these adults, more than half a million had thought seriously about suicide sometime during the past year. Members of sexual minorities were almost three times as likely as all adults in California to have had suicidal thoughts during the past year. This policy brief, ba...

Greater Pulp Yields per Acre per Year

Parts-per-million level loading organocatalysed enantioselective silylation of alcohols.

The field of organocatalysis has blossomed over the past few decades, becoming an alternative to transition-metal catalysis or even replacing the realm of transition-metal catalysis. However, a truly powerful organocatalyst with a high turnover number (TON) and turnover frequency (TOF) while retaining high enantioselectivity is yet to be discovered. Similar to metal catalysis, extremely low cat...

Palaeontology: The 165-Million-Year Itch

New flea-like fossils from China provide a rare, tantalizing glimpse of bizarre insects in the Cretaceous and Jurassic. Possibly the oldest flea-like animals known, they provide a challenge to the functional morphologist to infer which animals they may have targeted.
