Regulating gene transcription using light

Researchers led by Mustafa Khammash have developed a new method that uses blue light to control the transcription of DNA into RNA in single cells. The technology could also be used in tissue engineering and stem cell research.

Was life on the early Earth purple?

Early life forms on Earth may have been able to generate metabolic energy from sunlight using a purple-pigmented molecule called retinal that possibly predates the evolution of chlorophyll and photosynthesis. If retinal has ...

Discovery of a simple mechanism for color detection

Color vision, consisting of ocular color detection, is achieved with complicated neural mechanisms in the eyes. Researchers from Osaka City University in Japan have found color detection with a simple mechanism in the fish ...

Ancient pigment can boost energy efficiency

A color developed by Egyptians thousands of years ago has a modern-day application as well – the pigment can boost energy efficiency by cooling rooftops and walls, and could also enable solar generation of electricity via ...

Why huskies have blue eyes

DNA testing of more than 6,000 dogs has revealed that a duplication on canine chromosome 18 is strongly associated with blue eyes in Siberian Huskies, according to a study published October 4, 2018, in the open-access journal ...

Research accurately predicts US end-of-season corn yield

Crop yield predictions are a key driver of regional economy and financial markets, impacting nearly the entire agricultural supply chain. That's why economists, agricultural researchers, government agencies, and private companies ...

Chemists discover how blue light speeds blindness
