New research proves gender bias extraordinarily prevalent in science, technology, engineering and math fields

Science Daily - Lun, 2014-06-23 17:10
With everyone from the federal government to corporate America working to encourage more women to pursue careers in science, technology, engineering and math fields, you would think the doors would be wide open to women of all backgrounds. A new study shows that this could not be further from the truth and that gender bias among hiring managers in STEM fields is extraordinarily prevalent.

How does a soccer ball swerve? Smoothness of a ball's surface, in addition to playing technique, is a critical factor

Science Daily - Ven, 2014-06-20 02:06
It happens every four years: The World Cup begins and some of the world's most skilled players carefully line up free kicks, take aim -- and shoot way over the goal. The players are all trying to bend the ball into a top corner of the goal, often over a wall of defensive players and away from the reach of a lunging goalkeeper.

Criminal profiling technique targets killer diseases

Science Daily - Xov, 2014-06-19 17:54
A mathematical tool used by the Metropolitan Police and FBI has been adapted by researchers to help control outbreaks of malaria, and has the potential to target other infectious diseases. "The model has potential to identify the source of other infectious diseases as well, and we're now working with public health bodies to develop it further for use with TB, cholera and Legionnaires' disease," one researcher noted.

Strange physics turns off laser

Science Daily - Mar, 2014-06-17 15:29
Inspired by anomalies that arise in certain mathematical equations, researchers have demonstrated a laser system that paradoxically turns off when more power is added rather than becoming continuously brighter. The findings could lead to new ways to manipulate the interaction of electronics and light, an important tool in modern communications networks and high-speed information processing.

With light echoes, the invisible becomes visible

Science Daily - Mar, 2014-06-17 14:32
Scientists have developed a novel camera system which can see around the corner without using a mirror. Using diffusely reflected light, it reconstructs the shape of objects outside of the field of view. A laser shines on the wall; a camera watches the scene. Nothing more than white ingrain wallpaper with a bright spot of light can be seen through the lens. A computer records these initially unremarkable images and as the data is processed further, little by little, the outlines of an object appear on a screen.

A life well spent: Consume now (in case you die early)

Science Daily - Mar, 2014-06-10 17:20
An early death constitutes a serious loss that should imply compensation to the deceased person. But how – when the person is dead? A team of economists argues that a 'life well spent' might entail consuming more and working less earlier in life. They construct a mathematical model to measure the economic losses associated with an early death.

A new methodology developed to monitor traffic flow

Science Daily - Lun, 2014-06-09 14:38
Scientists have developed a new mathematical methodology to monitor traffic flow so that medium and long-term forecasts can be made. One of the key aspects of the methodology applied is its capacity to detect changes in traffic flow patterns.
