TEHRAN (ANA)- Autism reveals multiple biological subtypes, each with unique genetic and developmental patterns.

TEHRAN (ANA)- Scientists have uncovered why a critical part of photosynthesis only uses one of two seemingly identical pathways, revealing hidden energy barriers and structural nuances that could help engineer more efficient artificial systems.

TEHRAN (ANA)- Scientists have found a surprising connection between vitamin D and a single gene called SDR42E1.

TEHRAN (ANA)- New method developed by UTSW researchers removes mysterious organelles from stem cells and embryos to uncover their roles.

TEHRAN (ANA)- Researchers have discovered a new type of intestinal cell in pythons that helps them completely digest bones.

TEHRAN (ANA)- The new implant contains a reservoir of glucagon that sits beneath the skin and can be activated in an emergency, with no need for injections.

TEHRAN (ANA)- A gene called SDR42E1 has been identified as a key player in how our bodies absorb and process vitamin D, a report said, adding, researchers found that disabling this gene in colorectal cancer cells not only crippled their survival but also disrupted thousands of other genes tied to cancer and metabolism.

TEHRAN (ANA)- A new study reveals that neurons in the brain’s memory center, the hippocampus, continue to form well into late adulthood.

TEHRAN (ANA)- Newborns and individuals with Alzheimer’s disease have been found to share an unusual biological feature and both show high levels of a well-established Alzheimer’s biomarker.

TEHRAN (ANA)- A cloned yak was born via caesarean section at a yak breeding base in Damxung County, southwest China's Xizang Autonomous Region, researchers said.
