Jennifer Cheavens, assistant professor of psychology at Ohio State University and Laura Dreer of the University of Alabama at Birmingham say that hope can battle depression and discussed some of the latest research during a symposium Saturday Aug. 16 in Boston at the annual meeting of the American Psychological Association in Boston.

How do you measure 'hope' in people, depressed or not?

Cheavens uses a 12-item questionnaire developed by her mentor, the late C.R. Snyder of the University of Kansas. In this measure, hope has two components: a map or pathway to get what you want, and the motivation and strength to follow that path.

“If you feel you know how to get what you want out of life, and you have that desire to make that happen, then you have hope,” Cheavens said.

While many studies have examined cheating among college students, new research looks at the issue from a different perspective – identifying students who are least likely to cheat.

The study of students at one Ohio university found that students who scored high on measures of courage, empathy and honesty were less likely than others to report their cheating in the past – or intending to cheat in the future.

Moreover, those students who reported less cheating were also less likely to believe that their fellow students regularly committed academic dishonesty.

Recently some people have disputed the existence of the NEUTRON, which if this had any sound basis would cast doubt on some of my recent activities. Maybe this is because the neutron has not had much of an impact in popular culture. The only item that I remember is a song Yes to the Neutron Bomb (1981) by the Liverpool Group “Moderates”. I first went a-neutron scattering about three years ago. I arrived at the Rutherford Appleton Laboratory near Oxford, and went to the ISIS facility. After getting my badge and doing the safety test, I walked through the experimental hall (picture) and found myself entering a room entitled “LOQ CABIN”, although it did not look at all as if Abraham Lincoln had been born there. But what is the point of scattering neutrons?

A possible future way to prevent relapses into drug dependence has been discovered by researchers at Linköping University and the German cancer research center DKFZ. The target is the dopamine-producing nerve cells in the midbrain.

Earlier research has shown that these cells become more excitable when a person takes drugs. To find out the functional meaning of this, these researchers used a mouse model for cocaine dependence. When they blocked the cells’ receptors for glutamate - the brain’s most important signal substance -the risk of relapsing into addiction vanished. The findings are being published in the highly ranked journal Neuron.

Dopamine-producing nerve cells are central to the brain’s reward system.

Preliminary research led by Dr. Lawrence Cheskin, MD, Director of John Hopkins Weight Management Center, suggests increasing intake of low-energy density foods like mushrooms in place of high-energy-density foods like lean ground beef is a strategy for preventing or treating obesity. This is good news for the more than one-third of U.S. adults age 20 and older who are obese, according to the Center for Disease Control and who therefore have a greater risk factor for cardiovascular disease, certain types of cancer, and type 2 diabetes.

In a Mushroom Council study led by Dr. Cheskin, study participants were randomly chosen to receive either beef or mushroom lunch entrées over four days – lasagna, napoleon, sloppy Joe and chili. Subjects then switched entrées to consume the other ingredient (mushroom or beef) the following week.

Michael Phelps, Nastia Liukin, Misty May-Treanor and Lin Dan are four Olympic athletes who have each spent most of their life learning the skills needed to reach the top of their respective sports, swimming, gymnastics, beach volleyball and badminton (you were wondering about Lin, weren't you...) 

Their physical skills are obvious and amazing to watch.  For just a few minutes, instead of being a spectator, try to step inside the heads of each of them and try to imagine what their brains must accomplish when they are competing and how different the mental tasks are for each of their sports.

A middle school in East Harlem recently implemented a new invention in the area of rules. It can be described in two words—attendance court. In the area of tardiness, truant individuals may be able to add science as another excuse to their ongoing list.

“Telling a late person just to be on time is a little like telling a dieter to simply stop eating so much,” is a widely used quote from the San Francisco time management consultant Diana DeLonzor’s book "Never Be Late Again: 7 Cures for the Punctually Challenged." It is so simple that it’s a concept easily overlooked.

In her book DeLonzor attacks the issue of what she calls a "lifelong habit" as more than just a matter of poor time management, or rudeness.

Being late is something that DeLonzor suggests has a sort of appeal. “Repetitive lateness is more often related to personality characteristics such as anxiety or a penchant for thrill-seeking,” she writes. “Some people are drawn to the adrenaline rush of that last minute sprint to the finish line, while others receive an ego boost from over-scheduling and filling each moment with activity.”

Scientists at Michigan State University have identified a new protein necessary for chloroplast development that they say could ultimately lead to plant varieties tailored specifically for biofuel production.

Chloroplasts, which are specialized compartments in plant cells, convert sunlight, carbon dioxide and water into sugars and oxygen ("fuel" for the plant) during photosynthesis. The newly discovered protein, trigalactosyldiacylglycerol 4, or TGD4, offers insight into how the process works.

When a cell begins to multiply in a dangerously abnormal way, a series of death signals trigger it to self-destruct before it turns cancerous. In research in the August 15th issue of Genes & Development, Rockefeller University scientists using mice have figured out a way to amplify the signals that tell these precancerous cells to die. The trick: Inactivating a protein that normally helps cells to avoid self-destruction.

The work, led by Hermann Steller, Strang Professor and head of the Laboratory of Apoptosis and Cancer Biology, is the first to reveal the mechanism by which a class of proteins called IAPs regulates cell death. By exposing the mechanism in a living animal, the finding also marks a breakthrough in the field and opens the door for developing a new class of drugs that could aid in cancer therapy and prevention.

Scientists at the Smithsonian Institution have discovered a new species of bird in Gabon, Africa, that was, until now, unknown to the scientific community. Their findings were published in the international science journal Zootaxa today, Aug. 15.

The newly found olive-backed forest robin (Stiphrornis pyrrholaemus) was named by the scientists for its distinctive olive back and rump. Adult birds measure 4.5 inches in length and average 18 grams in weight. Males exhibit a fiery orange throat and breast, yellow belly, olive back and black feathers on the head. Females are similar, but less vibrant. Both sexes have a distinctive white dot on their face in front of each eye.

The bird was first observed by Smithsonian scientists in 2001 during a field expedition of the National Zoo's Monitoring and Assessment of Biodiversity Program in southwest Gabon. It was initially thought, however, to be an immature individual of an already-recognized species. Brian Schmidt, a research ornithologist at the Smithsonian's National Museum of Natural History and a member of the MAB program's team, returned to Washington, D.C., from Gabon in 2003 with several specimens to enter into the museum's bird collection. When he compared them with other forest robins of the genus Stiphrornis in the collection, Schmidt immediately noticed differences in color and plumage, and realized the newly collected birds might be unique.
