Nearly all species have some ability to detect light and at least three types of cells in the retina allow us to see images or distinguish between night and day. Now, researchers at the Johns Hopkins School of Medicine say they have discovered another type of cell that can sense light and contribute to vision.

Reporting in Nature, the team of neuroscientists say that retinal horizontal cells, which are nerve cells once thought only to talk to neighboring nerve cells and not even to the brain, are light sensitive themselves. 
A new technique has allowed researchers to make film bacteria infecting their living host.

Most studies of bacterial infection are done after the death of the infected organism a new technique developed by scientists at the University of Bath and University of Exeter has allowed researchers to make film bacteria and  follow the progress of infection in real-time with living organisms.

The researchers used developing fruit fly embryos as a model organism, injecting fluorescently tagged bacteria into the embryos and observing their interaction with the insect's immune system using time-lapse confocal microscopy.
Scientists at Penn State University, in collaboration with institutes in the US, Finland, Germany and the UK, have figured out the long-sought structure of a layer of C60 – carbon buckyballs – on a silver surface.  The results in Physical Review Letters and Physics  could help in the design of carbon nanostructure-based electronics.

Ever since the 1985 discovery of C60, this molecule, with its perfect geodesic dome shape has fascinated scientists, physicists, and chemists alike. Like a soccer ball, the molecule consists of 20 carbon hexagons and 12 carbon pentagons. The electronic properties of C60 are very unusual, and there is a massive research effort toward integrating it into molecular scale electronic devices like transistors and logic gates.
Citizen scientists working through an online project called Galaxy Zoo have discovered a group of rare galaxies called the "Green Peas" which could lend unique insights into how galaxies form stars in the early universe.

Galaxy Zoo users volunteer their spare time to help classify galaxies in an online image bank.  When they came across a number of objects that stuck out because of their small size and bright green color, they dubbed them the Green Peas. Employing the help of the volunteers to further analyze these strange new objects, the astronomers discovered that the Green Peas are small, compact galaxies forming stars at an incredibly high rate. 
Millions of children, as many as 2% of all births in the U.S. and Europe, have been born to couples with fertility problems through assisted reproductive techniques such as in vitro fertilization (IVF). Because it is a newer field, relatively little research has been conducted to evaluate the long term effects of assisted reproductive techniques. 

Research presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB) says that assisted reproductive techniques alter the expression of genes that are important for metabolism and the transport of nutrients in the placenta of mice. 
Abandoned mine shafts could be used to provide geothermal energy to local towns, say two engineers from the University of Oviedo in the journal Renewable Energy. They say the method they have developed makes it possible to estimate the amount of heat that a tunnel could potentially provide.

Rafael Rodríguez, from the Oviedo Higher Technical School of Mining Engineering and colleague María Belarmina Díaz have developed a "semi-empirical" method (part mathematical and part experimental) to calculate the amount of heat that could be produced by a mine tunnel that is due to be abandoned, based on studies carried out while it is still in use.
