Re "Senators aim stiff criticism at Gonzales," April 20 Atty. Gen. Alberto R. Gonzales has said that the eight U.S. attorneys were fired because of lapses of judgment and management of their offices. If the same criteria are applied to Gonzales, President Bush should ask for his resignation immediately. DAN CALDWELL Malibu So Gonzales can't recall -- which he said more than 50 times. No need to fret. Gonzales himself has approved a method of memory enhancement that just might help him. It requires only a couple of common household items -- a bathtub and a board.

Re "Is the GI Bill just an IOU?" Opinion, Oct. 25 I served in the military for four years. I qualified, applied for and was approved for the Post-9/11 GI Bill. My enthusiasm has been tempered by the VA's inability to process claims. Please don't mistake me: I'm thrilled veterans are applying, which accounts for the delay. Six weeks is what I budgeted for. It has now been eight weeks (two billing cycles) and payment has yet to be received. When I call the VA, I am told "any day now."

What are the advantages and disadvantages of using the supplement nitric oxide? Richard Sunland Nitric oxide is a gas naturally found in the body; its function is conveying information between cells. One of its main jobs is increasing blood flow by dilating blood vessels, and that's why it's sometimes given in supplement form to heart patients, orally and intravenously. In at least one study it's been shown to be effective for lowering blood pressure.

Can a private company own rights to your DNA? The nine justices of the Supreme Court will consider that question Monday as lawyers for Myriad Genetics make their best case that the company should be able to keep its patent on two genes known to influence the risk of developing breast cancer and ovarian cancer. Challenging that notion will be lawyers representing the Assn. for Molecular Pathology and other scientific organizations, which argue that allowing genes to be patented slows or shuts down scientific research involving those genes.

As part of a settlement with federal regulators, 13 lenders this week are starting to pay out $3.6 billion to more than 4 million troubled borrowers whose homes were in foreclosure proceedings in 2009 and 2010. A chart released Tuesday by the regulators showed that most of the borrowers would receive $300, the minimum allowed under the settlement terms. The maximum of $125,000 would go to 1,135 borrowers whose homes were seized while they were serving in the military or who were current on their payments.

When roasted at 475 degrees, coffee beans are sometimes described as rich and full-bodied. But for the full-bodied person who is not so rich, unroasted coffee beans - green as the day they were picked - may hold the key to cheap and effective weight loss, new research suggests. In a study presented Tuesday at the American Chemical Society's spring national meeting in San Diego, 16 overweight young adults took, by turns, a low dose of green coffee bean extract, a high dose of the supplement, and a placebo.

Khadijah Williams stepped into chemistry class and instantly tuned out the commotion. She walked past students laughing, gossiping, napping and combing one another's hair. Past a cellphone blaring rap songs. And past a substitute teacher sitting in a near-daze. Quietly, the 18-year-old settled into an empty table, flipped open her physics book and focused. Nothing mattered now except homework. "No wonder you're going to Harvard," a girl teased her. Around here, Khadijah is known as "Harvard girl," the "smart girl" and the girl with the contagious smile who landed at Jefferson High School only 18 months ago. What students don't know is that she is also a homeless girl.

Last of three parts No car, no work. That's the conclusion Lisa Twombly reached as she fought to hang on to her job as a caretaker for an elderly San Diego couple. Taking the bus and bumming rides from friends wasn't cutting it, and she was repeatedly late for work. Told she'd be fired if it happened again, Twombly put down $4,000 - all her savings - on a 9-year-old Chrysler Sebring with 95,000 miles. The dealership lent her the $2,600 balance at a steep 18% interest rate.

When Greg Louganis hit his head on the diving board and spilled his blood into the pool at the 1988 Olympic Games, did he have an obligation to disclose to doctors who treated him and to other athletes using the pool that he was HIV-positive?
