Bright Lights At Night Could Be Leading To More Depression

bright lights

For many, the harsh, bright glare of fluorescent street lights or office blocks which remain lit overnight has led to sleepless nights and subsequent bad moods.  But now psychologists from Ohio State University in the US, say that being unable to escape to the dark can affect personality, a person’s health and could lead to depression.

Vu1’s conceptual design for its R-30 bulb.

While compact fluorescent lights (CFLs) are currently the primary alternative to incandescent light bulbs, a company from Seattle predicts that its own novel light bulbs will eventually replace CFLs and LEDs. Vu1 (“view one”) Corporation has been working on its electron stimulated luminescence (ESL) bulbs, and has recently released a demo video (below).

Japanese Scientists Create World’s First Transgenic Primates

Japanese Scientists Create World’s First Trangenic Primates 

Japanese scientists announced  they had created the world’s first transgenic primates, breeding monkeys with a gene that made the animals’ skin glow a fluorescent green.

In a controversial achievement, Japanese scientists announced on Wednesday they had created the world’s first transgenic primates, breeding monkeys with a gene that made the animals’ skin glow a fluorescent green.

A New Way To Detect Cancer Early

A New Way To Detect Cancer Early 

 

A prototype device employs the same magnetic phenomenon used to write data to computer hard drives.

A new system for detecting cancer proteins uses the same magnetic phenomenon that lets computer hard drives read and write data. The Stanford University researchers developing the system hope that it will detect cancer in its earlier stages, when it’s easier to treat. MagArray, a startup in Sunnyvale, CA, will commercialize the technology.

Surgical Imaging System Turns Cancer Cells Neon

Surgical Imaging System Turns Cancer Cells Neon 

A real-time surgical imaging system (top) displays live video.  Image produced by the new system (bottom) shows a pig’s hind leg after injection of a contrast agent.  

Many cancer patients leave surgery still harboring dangerous tumor cells, while others suffer painful aftereffects because a surgeon has removed too much healthy tissue or nicked a nerve. A new imaging system that highlights cancerous tissue in lurid colors should help surgeons remove every last trace of cancer without harming the surrounding tissue. The system, currently in early clinical trials, uses a new class of contrast agents that emit near-infrared light and can attach to virtually any kind of tissue, cancerous or a healthy–showing surgeons just where to cut.
