Sea level rise poses particular risk for Asian megacities

Sea level rise this century may disproportionately affect certain Asian megacities, according to new research that looks at the effects of natural sea level fluctuations in addition to climate change. The study identified several Asian megacities that may face especially significant risks by 2100, including Chennai, Kolkata, Yangon, Bangkok, Ho Chi Minh City, and Manila.

Alex Murduagh and the Evolutionary Reason We’re Drawn to Violent Crime

If you haven’t heard the name Alex Murdaugh over the course of the past few months, you may just not have been paying attention.

Cable news carried Murdaugh’s testimony live and uninterrupted as it unfolded. In its...

IPK researchers provide insights into grain number determination mechanism of barley

Modifying inflorescences with higher grain capacity is vital for crop grain production. One recurring target is to select inflorescences with more branches or floral structures. Prominent examples include genes affecting floral identity or meristem determinacy, for which natural or induced variants profoundly change floral primordium number. Yet for temperate cereal crops, such as wheat and...

Developing nanoprobes to detect neurotransmitters in the brain

The animal brain consists of tens of billions of neurons or nerve cells that perform complex tasks like processing emotions, learning, and making judgments by communicating with each other via neurotransmitters. These small signaling molecules diffuse—move from high to low concentration regions—between neurons, acting as chemical messengers.

The world's first horse riders found near the Black Sea

Researchers have discovered evidence of horse riding by studying the remains of human skeletons found in burial mounds called kurgans, which were between 4,500 and 5,000 years old. The earthen burial mounds belonged to the Yamnaya culture. The Yamnayans had migrated from the Pontic-Caspian steppes to find greener pastures in today´s countries of Romania and Bulgaria up to Hungary and Serbia.

Earliest evidence of horseback riding found in ‘eastern cowboys’

About 5300 years ago, people from the steppes of modern-day Russia and Ukraine expanded rapidly across Eurasia. Within a few centuries these “Yamnaya” left a lasting genetic mark on populations from central Europe to the Caspian Sea. Today, archaeologists call them “eastern cowboys” for their livestock herding and highly mobile lifestyle. But one part of...
