Researchers found that by combining information from different senses dogs form abstract mental representations of positive and negative emotional states in people. Previous studies have shown that dogs can differentiate between human emotions from signs such as facial expressions.

Shareholders including power tower pioneer Brightsource Energy as well as General Electric, which will provide the turbine, want to build more such towers around the world.     "We're making strides in efficiency, we're making strides in compressing the time of construction," said Megalim's Chief Executive Eran Gartner.

The letters on the brooch, which dates to a time when the Roman Empire controlled Britain, contain different meanings depending on how they are read. When read left to right, the letters form a monogram for "Roma," the name of Rome and its deity.

"Based on our new study, we now have three different species of Rhinconichthys from three separate regions of the globe, each represented by a single skull," study co-researcher Kenshu Shimada, a paleobiologist at DePaul University in Chicago, said in a statement.

Excavators from the Museum of London Archaeology (MOLA) were carefully digging for Roman artifacts at 21 Lime Street, near Leadenhall Market in central London, ahead of the construction of an office building at the site.

"These cases of people disappearing for 30 years and then waking up and coming to —these are very rare," Brandt told Live Science. What is amnesia?

"Our data may indicate prolonged presence of [Zika] virus in semen, which, in turn, could indicate a prolonged potential for sexual transmission," the researchers, from Public Health England, part of the U.K.'s Department of Health, write in an article to be published in the May issue of the journal Emerging Infectious Diseases. The Zika virus, which is currently spreading in more than 20 countries in Central and South America, is usually transmitted by mosquitoes.

The first locally transmitted case of Zika was reported there in late December. The virus poses a significant concern to pregnant women, as it may lead to microcephaly (small head size) and other birth defects in their children.

Scientists investigated the potential for producing more food with the same amount of water by optimising rain use and irrigation. As global warming is expected to worsen droughts and change rainfall patterns, water availability becomes even more crucial in reducing threats to the global food supply. Read More » 'MyShake' App Turns Your Smartphone into Earthquake Detector Seismologists and app developers are shaking things up with a new app that transforms smartphones into personal earthquake detectors. By tapping into a smartphone's accelerometer — the motion-detection instrument — the free Android app, called MyShake, can pick up and interpret nearby quake activity, estimating the earthquake's location and magnitude in real-time, and then relaying the information to a central database for seismologists to analyze. In time, an established network of users could enable MyShake to be used as an early- warning system, the researchers said.

The news reported around the world was startling — that some 150,000 Adélie penguins have died in Antarctica because a colossal iceberg cut off their sea access. It wouldn't be the first time Adélie penguins marched to new digs. Read More » Europe launches satellite to help track global warming Europe launched a satellite on Tuesday that will help predict weather phenomena such as El Nino and track the progress of global warming as part of the multibillion-euro Copernicus Earth observation project. "When we speak about global warming we often focus on rising air temperatures, but 90 percent of the energy put out on our planet ends up in the ocean," Volker Liebig, director of the European Space Agency's (ESA) Earth Observation program, told Reuters ahead of the launch. The Copernicus project, for which the European Union and the European Space Agency (ESA) have committed funding of more than 8 billion euros ($9 billion) until 2020, is described by the ESA as the most ambitious Earth observation program to date.
