Payroll deduction savings programs improve retirement security: State auto IRAs are vital to expanding coverage

Payroll deduction savings programs improve retirement security: State auto IRAs are vital to expanding coverage

New AARP research based on a methodology published by the Wharton School finds that about half of American working adults lack access to a payroll-deduction workplace retirement savings plan, making it much more difficult to save for retirement.

Mapping molecular arrangements to pave the way for better catalytic systems
Bright spots represent individual catalyst molecules captured under cryogenic conditions to prevent clustering.

Eric Stach of the School of Engineering and Applied Science and colleagues used neural networks to better identify the characteristics of catalysts that drive the creation of liquid fuels from sunlight. Shown here: The arrangement of a catalyst molecule, as observed under cryogenic conditions. The bright spots represent individual or small groups of molecules immobilized on a surface and the cryogenic temperature helps minimize clustering caused by the electron beam during imaging, allowing scientists to study the molecule’s distribution more accurately.

Mapping molecular arrangements to pave the way for better catalytic systems

The Stach Group in Penn Engineering led a collaborative team identifying how chemical catalysts drive the creation of liquid fuels from sunlight, paving the way for more efficient removal of greenhouse gases from the atmosphere.

The other emissions coming from cars

Tiny tire particles discharge into the environment every time a vehicle brakes, accelerates, or rounds a curve. In a UN brief, geochemist Reto Gieré and colleagues aim to educate the world about this lesser-known environmental obstacle.
