Are you ugly?  Maybe that's something else to blame your mother about.

Female cognitive ability can impact how handsome males become over evolutionary time, say biologists from The University of Texas at Austin, Louisiana State University Health Sciences Center and the Smithsonian Tropical Research Institute. Males across the animal world have evolved elaborate traits to attract females, from huge peacock tails to complex bird songs and frog calls. But there is a price - predators are attracted to increased elaboration, placing an enormous cost to males with these sexy traits. In a new paper, a group of biologists have shown that females can also limit the evolution of increased elaboration.

The region around the Hubble Deep Field (HDF), originally captured by the Hubble Space Telescope (HST) in the mid 1990s, led to the discovery of numerous galaxies billions of light years distant and provided direct visual evidence of the evolution of the Universe. First results from the new imaging, which uses observations from the UK's newly upgraded e-MERLIN radio telescope array together with the EVLA radio array based in New Mexico, show galaxies some 7 billion light years away in unprecedented detail. 

After WikiLeaks released classified and sensitive government documents, predictions of the scale and significance of their impact were overstated.

The desire/hope of proponents that the WikiLeaks disclosures of 2010 meant conventional mechanisms for controlling government-held information wee breaking down, heralding a new world of 'radical transparency', were short-lived. Old-style secrecy is still there, argues Alasdair Roberts of Suffolk University Law School.  Leak, publish, and wait for the inevitable outrage is easily defeated in practice.

It turns out radical transparency is hard to achieve and  a technological fix alone will not do it.

A device the size of a home washing machine uses bacteria growing in municipal sewage to make electricity - and also clean up the sewage at the same time. 

Current wastewater treatment technology involves a number of steps designed to separate the solid and liquid components of sewage and clean the wastewater before it is released into a waterway. This often involves settling tanks, macerators that break down larger objects, membranes to filter particles, biological digestion steps and chemicals that kill harmful microbes. One estimate puts their energy use at 2 percent of overall consumption in the U.S.

In the era of Big Science, it is often assumed that cutting-edge research can't be done cheaply.  Yet even now a piece of tape can lead to a Nobel prize.  Andre Geim and Konstantin Novoselov  got one that way, for their discovery of graphene, a type of carbon one atom thick but more than 100 times stronger than steel.

Sure, we all know graphene will lead to bendable computer screens and ultralight materials but it turns out graphene may also revolutionize genetic sequencing. 

One strategy for tackling hard-to-treat bacterial infections could be viruses that can target and destroy bacteria. The development of such novel therapies is being accelerated in response to growing antibiotic resistance, says Dr David Harper at the Society for General Microbiology's Spring Conference in Dublin.
