Improving bloodstain pattern analysis with fluid dynamics

Often left on the surfaces of a crime scene or on the clothes of an accused criminal, blood backspatter can be used as evidence for forensic scientists to reconstruct what occurred. However, the fluid dynamics at play are ...

Ingredients involved in splashing revealed

"Splashing" plays a central role in the transport of pollutants and the spread of diseases, but while the sight of a droplet striking and splashing off of a solid surface is a common experience, the actual physical ingredients ...

Forensics puzzle cracked via fluid mechanical principles

In 2009, music producer Phil Spector was convicted for the 2003 murder of actress Lana Clarkson, who was shot in the face from a very short distance. He was dressed in white clothes, but no bloodstains were found on his clothing—even ...

Bubble study could improve industrial splash control

(Phys.org)—For the first time, scientists witnessed the details of the full, ultrafast process of liquid droplets evolving into a bubble when they strike a surface. Their research determined that surface wetness affects ...

Interactive surfaces enter a whole new dimension of flexibility

An "interactive surface" refers to an interface whose input and output share a common surface that can be manipulated intuitively with the fingers. However, ordinary multi-touch displays, e.g., liquid crystal displays (LCD), ...

Cracking open diamonds for messages from the deep earth

Geochemist Yaakov Weiss deals in diamonds. Not the brilliant jewelry-store kind, but the flawed, dirty-looking ones used more for industry than decoration. Gem-grade diamonds are generally pure crystallized carbon, ...

How cells 'eat' their own fluid components

Autophagy is a fundamental cellular process by which cells capture and degrade their own dysfunctional or superfluous components for degradation and recycling. Recent research has revealed that phase separated droplets have ...

Droplets perform daredevil feats on gel surfaces

Welcome to the amazing world of soft substrates. These materials are made of silicon gels and have the same texture as panna cotta—but without the delicious flavor. They are used in a range of applications, especially in ...
