Scientists find holes in light by tying it in knots

A research collaboration including theoretical physicists from the University of Bristol and Birmingham has found a new way of evaluating how light flows through space—by tying knots in it.

Start codons in DNA may be more numerous than previously thought

For decades, scientists working with genetic material have labored with a few basic rules in mind. To start, DNA is transcribed into messenger RNA (mRNA), and mRNA is translated into proteins, which are essential for almost ...

Research leads to portable DNA testing device

( —More than 10 years of research and development have led to the introduction of a portable DNA analysis device that relies on technology developed by University of Virginia professor James P. Landers and a team ...

The number of armed conflicts increased strongly in 2011

Last year, the number of armed conflicts in the world increased markedly, with the strongest increase taking place in Sub-Saharan Africa. This is the conclusion in a new report by researchers at the Uppsala Conflict Data ...

First noiseless single photon amplifier

Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise.

Physicists squeeze light on quantum scale

An international team of physicists has pushed the boundaries on ultra-precise measurement by harnessing quantum light waves in a new way.

Opening the path to scaling silicon quantum computers
