Breast reconstruction patients often less satisfied than expected post surgery

A new study published in JAMA Surgery found that breast cancer patients who undergo mastectomy with or without immediate reconstruction tend to be less satisfied than expected with their physical and sexual health post-surgery. Women who choose immediate reconstruction overestimated their satisfaction with appearance, while those who d...

Even without the clean power plan, US can achieve Paris Agreement emissions reductions

Researchers from Carnegie Mellon University have found that US power sector carbon dioxide emissions are on track to meet near-term targets under the Paris Agreement despite the Trump Administration's withdrawal of the Clean Power Plan. A strong link between natural gas prices and emission reductions has been identified, with declining...

Penn engineers test drug transfer using placenta-on-a-chip

Researchers at the University of Pennsylvania have demonstrated the feasibility of their organ-on-a-chip platform in studying drug transport across the human placental barrier. The study found that the placenta-on-a-chip successfully emulated the protective mechanism against toxic drugs, paving the way for its use as a screening platform.

Lab-grown human cerebellar cells yield clues to autism

Researchers at Boston Children's Hospital used stem cell technology to create Purkinje cells from patients with tuberous sclerosis complex, a genetic syndrome often linked to autism. The lab-grown cells showed structural abnormalities and impaired development of synapses, which may help explain how autism develops at the molecular level.

Cells communicate in a dynamic code

Caltech scientists have discovered that cells can transmit multiple messages through the Notch signaling pathway by encoding them rhythmically over time. This discovery reveals that cellular messaging is closer to sending smoke signals than texting, and cells use temporal patterns to differentiate between similar ligands.
