Obama Offers to Cut Corporate Tax Rate to 28%

WASHINGTON — President Obama will ask Congress to scrub the corporate tax code of dozens of loopholes and subsidies to reduce the top rate to 28 percent, down from 35 percent, while giving preferences to manufacturers that would set their maximum effective rate at 25 percent, a senior administration official said on Tuesday
Mr. Obama also would establish a minimum tax on multinational corporations’ foreign earnings, the official said, to discourage “accounting games to shift profits abroad” or actual relocation of production overseas.

With the framework for changes that the Treasury secretary, Timothy F. Geithner, will outline on Wednesday, Mr. Obama will enter an election-year debate with Republicans in Congress and in the presidential race who seek even lower taxes for businesses. But an overhaul of the corporate code is unlikely this year, given that political backdrop and the complexity of an undertaking that would generate a lobbying frenzy as businesses vie to defend old tax breaks or win new ones.

The announcement comes two days before Mitt Romney, a Republican candidate for president, is expected to expand on his economic platform in Detroit.

The administration plan to revamp a corporate code that is widely derided as inefficient and anticompetitive has been in the works at Treasury for two years, and is a priority of Mr. Geithner. Yet he has been preoccupied with crisis management, and is unlikely to see the project through since he plans to leave office after this year.

How Exercise Fuels the Brain

Moving the body demands a lot from the brain. Exercise activates countless neurons, which generate, receive and interpret repeated, rapid-fire messages from the nervous system, coordinating muscle contractions, vision, balance, organ function and all of the complex interactions of bodily systems that allow you to take one step, then another.
This increase in brain activity naturally increases the brain’s need for nutrients, but until recently, scientists hadn’t fully understood how neurons fuel themselves during exercise. Now a series of animal studies from Japan suggest that the exercising brain has unique methods of keeping itself fueled. What’s more, the finely honed energy balance that occurs in the brain appears to have implications not only for how well the brain functions during exercise, but also for how well our thinking and memory work the rest of the time.
For many years, scientists had believed that the brain, which is a very hungry organ, subsisted only on glucose, or blood sugar, which it absorbed from the passing bloodstream. But about 10 years ago, some neuroscientists found that specialized cells in the brain, known as astrocytes, that act as support cells for neurons actually contained small stores of glycogen, or stored carbohydrates. And glycogen, as it turns out, is critical for the health of cells throughout the brain.

In petri dishes, when neurons, which do not have energy stores of their own, are starved of blood sugar, their neighboring astrocytes undergo a complex physiological process that results in those cells’ stores of glycogen being broken down into a form easily burned by neurons. This substance is released into the space between the cells and the neurons swallow it, maintaining their energy levels.
