Researchers found that women caregivers experience significant emotional distress, which accumulates over time, but adapt physically to caregiving responsibilities, and physical limitations often stabilize after initial increases
Researchers found that treated sleep apnea patients experienced no auto accidents over two years. A new biochemical marker for acute lung injury has been discovered, correlating with damage to epithelial cells in the lungs. This discovery may lead to future blood tests for the deadly condition.
New research refutes claims that U.S. forests and vegetation are 'sequestering' enough carbon to offset fossil fuel emissions, suggesting at least 70-90% of emissions stay in atmosphere or be sequestered elsewhere. The study's findings have important implications for the role of the U.S. in combating global warming.

By understanding how gelsolin works, scientists hope to develop new cancer-fighting drugs by stimulating or blocking its activation.
A new study found that primary care clinics serving low-income populations maintained their traditional market share of Medi-Cal patients despite a decline in total Medi-Cal beneficiaries. However, these clinics still face significant financial challenges due to cost control measures under managed care.
A study by Johns Hopkins researchers found that videotaping surgeries can improve outcomes in radical prostatectomy. The study, which involved 62 patients, showed that minor differences in surgical techniques can have a major impact on results. Surgeons who perform successful procedures should review the footage to identify key factors.
The nation won't meet its 15% smoking prevalence goal for 2000, with over 25% of US adults currently smoking. Effective strategies like cognitive behavioral therapies have been developed, but more work is needed to reach low-income and minority populations.

By blocking the sympathetic nervous system, they found a potential pathway to develop a life-saving antidote for cocaine overdoses.
A new study suggests that Hillary Clinton's popularity among the American public is driven mostly by media coverage, with less influence from partisanship and national issues. The research found that negative media coverage has a greater impact on public reaction than positive coverage.
Researchers at UCSF have discovered how Mycobacterium tuberculosis outsmarts the immune system to cause disease. The microbe disrupts a protein called STAT1, blocking macrophages' ability to respond to interferon gamma, allowing it to survive and infect other cells.

The study found that these buildings are often constructed with heavier materials than recommended, increasing the risk of damage during earthquakes.
Research indicates the Indian Ocean has its own El Niño-like phenomenon characterized by an east-to-west oscillation of warm waters affecting other parts of the world. The study found significant warming of the western portion of the Indian Ocean in 16 out of 48 years between 1950 and 1998, but only three were active El Niño years.
A new study published in Health Psychology contradicts long-held notions about the connection between breast cancer and psychological factors. The researchers found modest associations with certain psychosocial factors, but emphasized that biology remains the primary factor in breast cancer development.

The researchers developed a team-oriented training to help work groups address co-worker substance use and promote employee well-being.
Researchers at the University of Pennsylvania Cancer Center found that bilateral prophylactic oophorectomy reduces breast cancer risk in women with a BRCA1 gene mutation. After 10 years, the incidence of breast cancer among women who had their ovaries removed was significantly lower than those who did not.
A study of 182 Oklahoma City bombing survivors revealed high rates of postdisaster psychiatric disorders, with 45% experiencing symptoms in the six months following the explosion. The investigation also identified specific symptoms that indicated the need for treatment, including avoidance and numbing symptoms.
Researchers found that the Rpm1 resistance gene in Arabidopsis is approximately 9.8 million years old, with minimal changes over time, contradicting the 'arms race' theory. The study suggests an alternative 'trench warfare' model, where cycles of disease epidemics maintain stable forms of resistance and susceptibility genes.
A University of Michigan study found that a low sense of belonging is a stronger predictor of major depression than other factors. The research analyzed data from 31 clients with depression and 379 community college students, concluding that feeling connected to others is crucial in overcoming depression.
Long-term societal changes, particularly the aging baby boomer generation, contributed to a significant decline in serious crimes during the Clinton presidency. The strong economy and increased community-based crime prevention initiatives also played a crucial role in reducing crime rates.
