Novel brain areas associated with the recognition of gender, ethnicity and the identity of faces

Scientists discovered distinct brain regions processing gender, ethnicity and facial identity, contradicting previous assumptions about face recognition. These findings have implications for understanding conditions like autism spectrum disorders and may lead to improved methods for enhancing face recognition abilities.

Mapping the wake of a pending quake

Researchers have modeled past tsunamis to determine the likelihood of future waves and potential impacts on cities along the Sumatran coast. The study reveals that coastal communities face substantial exposure to tsunami surges, particularly in cities like Bengkalu and Padang.

Teens who smoke have increased risk of developing asthma

Children who smoke cigarettes have nearly four times the risk of developing asthma in their teens, and those exposed to cigarette smoke in utero face an even higher risk. The study draws on data from the Children's Health Study, a longitudinal study of respiratory health among children in southern California communities.

Mass extinction's cause: 'Sick Earth'

Research led by USC earth scientist David Bottjer suggests the Earth's environmental stressors led to mass extinction, contradicting meteorite strike theory. The study proposes a warming Earth and reduced ocean circulation as key factors in creating an environment where toxic hydrogen sulfide dominated, leading to species disappearances.

USC groups present at Neuroscience 2006

Researchers at USC have made significant discoveries in the fight against Alzheimer's disease. A study found that hormone replacement therapy may lower Alzheimer's risk by as much as 50 percent in younger women. Additionally, a new treatment approach for ALS and Parkinson's disease has shown promising results, with exercise interventio...

USC-led study suggests little benefit from antipsychotics in Alzheimer's

A nationwide study led by USC professor Lon Schneider found that most Alzheimer's patients prescribed antipsychotic drugs discontinue use due to severe side effects, despite showing some effectiveness in managing delusions and agitation. The study suggests that these medications should be used with caution and only when necessary.

Powerful genome ID method extended to humans

A novel genome mapping method has been extended to humans, offering a faster and more cost-effective tool than traditional DNA sequencing. The algorithm makes it possible to optically map the human genome, revealing large-scale structure and detecting genomic abnormalities. This breakthrough may accelerate research in cancer biology.

Cell's fight against cancer revealed

A University of Southern California-led research group used X-ray crystallography to study the struggle between LTag, a cancer-causing protein, and p53, a key tumor suppressor. The study found that LTag inhibits p53's role by tying up six molecules, but p53 fights back by preventing virus replication.

Bacteria can help predict ocean change

A new study by University of Southern California researchers reveals that most bacteria species are predictable and follow specific conditions. By understanding these patterns, scientists can improve models for ocean change, providing a more accurate prediction of how the oceans will evolve.

Multiple Sclerosis in genetically susceptible twins is augmented by the northern environment

A new study of twins found that genetic susceptibility to Multiple Sclerosis is significantly increased among those born in the northern environment, with a higher concordance rate among identical twins. Northern residence also contributed to an earlier onset of the disease, suggesting environmental factors play a crucial role.

Weight lifting can help overweight teens reduce risk of diabetes

A University of Southern California study found that strength training exercise can prevent or delay the onset of diabetes in overweight teens. Overweight Latino teenage boys who lifted weights twice per week for 16 weeks significantly reduced their insulin resistance, a condition common in obese children and precursor to diabetes.

Fitting software to students

A recent study at the University of Southern California found that motivated students excel in Intelligent Tutoring Systems (ITS), while disengaged students surprisingly show high levels of learning-oriented behavior. The research suggests that ITS can reach struggling students through private learning opportunities, and future models ...

USC/Duke team lets there be leisurely light

The USC/Duke team has made significant improvements in controlling light pulses, achieving a slowdown of up to 20-fold increase over previous methods. By using a simple optical fiber and exploiting the Brillouin effect, they can potentially accommodate higher data rates and enable more efficient processing with photonics.

DNA: Bacteria's survival ration

A recent study found that bacteria can utilize DNA as a critical food source, enabling them to outcompete other microbes and survive longer. The study identified eight genes necessary for this process, known as nutritional competence, which could have applications in medical research and the development of genetic antibiotics.

Self-esteem falters among Chinese teens

A recent USC study found that Chinese teens who perceive themselves as overweight, even if they are normal or underweight, are at a higher risk for depression and school-related stress. Girls in the study reported lower grade point averages when they felt overweight, while boys exhibited more aggressive behavior.

Childhood infections stunt growth, shorten life

Researchers found that survivors of generations with rampant childhood infection were shorter and died sooner than those from less infected generations. Childhood diseases like respiratory infections and diarrhea reduced growth rates. Improved public health practices led to increased height and longevity.
