Ancient Martian lake system records two water-related events Posted: 25 Mar 2015 06:07 PM PDT Researchers have completed a new analysis of an ancient Martian lake system in Jezero Crater, near the planet's equator. The study finds that the onslaught of water that filled the crater was one of at least two separate periods of water activity in the region surrounding Jezero.

Just right: A spider's tale of finding the perfect sized hole for their nest Posted: 25 Mar 2015 06:05 PM PDT A new study shows that southern house spiders are making size-related choices about holes and cavities in which to build their nests.

A mile deep, ocean fish facing health impacts from human pollution Posted: 25 Mar 2015 12:23 PM PDT Deep-water marine fish living on the continental slopes at depths from 2,000 feet to one mile have liver pathologies, tumors and other health problems that may be linked to human-caused pollution, one of the first studies of its type has found. Fish have been found with a blend of male and female sex organs including. The findings appear to reflect general ocean conditions.

A new spin on Saturn's peculiar rotation Posted: 25 Mar 2015 12:23 PM PDT The precise measurement of Saturn's rotation has presented a great challenge to scientists, as different parts of this sweltering ball of hydrogen and helium rotate at different speeds whereas its rotation axis and magnetic pole are aligned. A new method leads to a new determination of Saturn's rotation period and offers insight into the internal structure of the planet, its weather patterns, and the way it formed.

Thousands of atoms entangled with a single photon Posted: 25 Mar 2015 12:19 PM PDT Physicists have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results represent the largest number of particles that have ever been mutually entangled experimentally.

Supermassive black hole clears star-making gas from galaxy's core Posted: 25 Mar 2015 12:18 PM PDT A new study provides the first observational evidence that a supermassive black hole at the center of a large galaxy can power huge, wide-angled outpourings of material from deep inside the galaxy's core. These outflows remove massive quantities of star-making gas, thus influencing the size, shape and overall fate of the host galaxy.

Just slip out the back, Jack: Are humans hardwired to break-up and move on? Posted: 25 Mar 2015 12:17 PM PDT When it comes to romantic relationships, a research review article suggests humans are wired to break-up and move on. Drawing largely upon the field of evolutionary psychology, they say men and women might break up for different reasons. For instance, a man is more likely to end a relationship because a woman has had a sexual relationship with another man. On the other hand, a woman may be more likely to break up if her partner has been emotionally unfaithful.

Two most destructive termite species forming superswarms in South Florida Posted: 25 Mar 2015 12:17 PM PDT Two of the most destructive termite species in the world are swarming together in South Florida. They might mate, forming a hybrid, and that worries the UF/IFAS scientists who found the superswarm.

New form of ice: Square ice filling for a graphene sandwich Posted: 25 Mar 2015 11:02 AM PDT Water exists in myriad forms, and for poets and scientists alike this structurally simple yet at the same time behaviourally complex molecule never fails to fascinate. In our everyday lives we are familiar with water in its more common liquid, ice and vapour forms. Scientists also study water under more extreme conditions, including at high pressures, where it can exist in the solid state even at room temperature.

Unexplained warm layer discovered in Venus' atmosphere Posted: 25 Mar 2015 10:17 AM PDT Scientists have found a warm layer in Venus' atmosphere, the nature of which is still unknown. The researchers made the discovery when compiling a temperature map of the upper atmosphere on the planet's night side based on the data collected by the Venus Express probe.

Explosions of Jupiter's aurora linked to extraordinary planet-moon interaction Posted: 25 Mar 2015 08:08 AM PDT New observations of the planet's extreme ultraviolet emissions show that bright explosions of Jupiter's aurora likely also get kicked off by the planet-moon interaction, not by solar activity.

Damselfly war games: Flying insects take note of opponents' strengths, abilities before entering into a fight Posted: 25 Mar 2015 07:19 AM PDT Before a male damselfly hot-headedly enters into a duel of aerial sparring, it first works out its strategy. It gives its opponent's wings a once-over to assess its strength, knowing that more transparent wings and larger red spots generally show a stronger rival. Those who then decide to engage in long fights either try to wear their opponent down, or dazzle them with brilliant aerial moves that are too hard to follow, scientists have found.

Actor Benedict Cumberbatch and Richard III are cousins Posted: 25 Mar 2015 05:24 AM PDT An historian whose genealogy research helped to confirm the identity of the remains found in the Grey Friars car park as those of King Richard III has discovered a direct link between the English actor Benedict Cumberbatch and the former Plantagenet monarch.

Robots on reins could be the 'eyes' of firefighters Posted: 25 Mar 2015 05:20 AM PDT Firefighters moving through smoke-filled buildings could save vital seconds and find it easier to identify objects and obstacles, thanks to revolutionary reins that enable robots to act like guide dogs.

NASA satellites catch 'growth spurt' from newborn protostar Posted: 24 Mar 2015 03:36 PM PDT Using data from orbiting observatories and ground-based facilities, astronomers have discovered an outburst from a star thought to be in the earliest phase of its development. The eruption, scientists say, reveals a sudden accumulation of gas and dust by an exceptionally young protostar known as HOPS 383.

Leaders and their followers tick in sync Posted: 24 Mar 2015 12:36 PM PDT Great leaders are often good communicators. In the process of communication, the relationship between leaders and their followers develops spontaneously, according to new research. When a member becomes the group leader, the leader's brain activity in the left temporo-parietal junction, known as representing others' mental states, begins to synchronize with that in the same area of their followers. Based on interpersonal neural synchronization, the researchers were even able to predict who would emerge as leader of a group, and when. The findings also suggest that interpersonal neural synchronization is more likely due to the communication skills of the leader and less likely due to how much they speak. Thus, in a group of peers, the individual who says the right things at the right time usually emerges as the leader.
