A gene mutation associated with colon cancer has been discovered in an 18th century Hungarian mummy. The finding suggests colon cancer's genetic roots predate modern risk factors.


For the first time researchers have identified the lifelong changes in gene expression in the brains of people born with Down syndrome (DS). The findings, which appear in the journal Neuron, may lead to possible therapies for DS patients.

Science AMA Series: Hi Reddit! I'm NOAA scientist Lee Benaka. I work to reduce bycatch in U.S. ocean fisheries to ensure that our fisheries remain sustainable and that protected species are given their best chance to recover. What is bycatch and why does it matter? Find out here – Ask Me Anything!

Hello Reddit!

I'm Lee Benaka (Fishery Management Specialist, NOAA Fisheries Office of Science and Technology). While U.S. fisheries are among the world’s most sustainable, bycatch is a complex, global issue that threatens the sustainability and resiliency of our fishing communities, economies, and ocean ecosystems. NOAA Fisheries works hard to minimize bycatch in U.S. fisheries, ensuring our fisheries remain sustainable and protected species are given their best chance to recover.

Bycatch occurs when fishermen catch and discard animals that they do not want, cannot sell, or are not allowed to keep. Discarded catch represents loss of opportunity for fishermen and too frequently, loss of marine life, which can impact vulnerable ecosystems and slow the rebuilding process for overfished stocks or place protected species at further risk. NOAA Fisheries works with fishermen, scientists, and managers to mitigate the negative effects of bycatch by developing innovative fishing gear and tracking bycatch through regular data collection.

Bycatch is an issue that impacts the overall health of our oceans and the sustainability of our seafood industry. If you want to learn more about bycatch and how it can be reduced, this is your chance. I'll be back at 10 am EST (7 am PST, 3 pm UTC) to answer your questions, Ask me anything!
