Physicists Cool Microscopic Drum to Near Absolute Zero

Physicists Cool Microscopic Drum to Near Absolute Zero

According to a paper recently published in Nature, researchers at the National Institute of Standards and Technology (NIST) have cooled a vibrating drum to an unprecedented one-fifth of a quantum of energy, approaching the previously perceived limit of absolute zero (1). Scientists use temperature to measure the thermal motion of […]

Sewage Can Soon Be Converted into Bio-based Fuel

Sewage Can Soon Be Converted into Bio-based Fuel

Recent research findings at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) has shown that wastewater treatment plants may have the potential to produce biocrude oil, which is a petroleum-substitute synthetic fuel, from ordinary sewage (1). The technological process being considered is called hydrothermal liquefaction (HTL) (2). In HTL, […]

 
 

Novel 3-D Printing Ink Shows Promise for Bone Regeneration

Novel 3-D Printing Ink Shows Promise for Bone Regeneration

Engineers at Northwestern University have recently produced a synthetic bone material, specifically aimed to treat pediatric patients with bone defects using an innovative 3-D printing system. Many complications arise during bone implantation surgery, especially for children. Bone used for surgery is typically extracted from other parts of the body in […]

 
 

New research explains how aquatic birds dive safely at high speeds to hunt prey

New research explains how aquatic birds dive safely at high speeds to hunt prey

A research team at Virginia Tech has developed a mechanism to explain how seabirds safely plunge into the ocean when looking for food despite their slim necks (1). In order to surprise their targets, many species of seabirds dive into the ocean at speeds faster than 60 miles per hour. […]
