NOAA Research covered the globe in 2011

In 2011, NOAA researchers made significant discoveries about storm systems, oceanic and atmospheric research, and environmental threats. They found that human-caused aerosol increases linked to decreased monsoon rainfall in South Asia, while also improving weather forecasting capabilities.

How pregnancy changes a woman's brain

Research suggests that pregnancy's massive hormonal fluctuations prepare a woman's brain for motherhood, leading to improved stress tolerance and baby sensitivity. However, there may be costs to these changes, and more comprehensive studies are needed to develop interventions for at-risk mothers.

Autologous stem cell transplantation does not improve os in patients with follicular lymphoma

A systematic review and meta-analysis of randomized control trials found no improvement in overall survival for adult patients with advanced follicular lymphoma who received high-dose chemotherapy and ASCT compared to conventional-dose chemotherapy alone. The study concluded that HDC-ASCT is not effective as a primary treatment option.
