Cheap, eco-friendly catalyst opens new possibilities for organic molecules built from pyruvate

Sciencedaily.com 

Chemists have developed an organic catalyst that can drive reactions using pyruvate -- a key biomolecule in many metabolic pathways -- that are difficult and complicated to achieve using conventional industrial techniques. The research is an important step towards simplifying the production process and increasing the range of molecules that can be built from pyruvate, like amino acids or glycolic acids, which are used in drug discovery efforts and medications.

On Jupiter's moon Europa, 'chaos terrains' could be shuttling oxygen to ocean

Sciencedaily.com 

Researchers have built the world's first physics-based computer simulation of oxygen transport on Europa, finding that it's possible for oxygen to drain through the moon's icy shell and into its ocean of liquid water -- where it could potentially help sustain alien life -- by hitching a ride on salt water under the moon's 'chaos terrains.' The results show that not only is the transport possible, but that the amount of oxygen brought into Europa's ocean could be on a par with the quantity of oxygen in Earth's oceans today.

Can supermarkets coax people into buying healthier food?

Sciencedaily.com 

Restricting supermarket placement of less healthy items and increasing the availability of healthier alternatives in these stores may be promising interventions to encourage healthier purchasing behaviors, according to two new studies.

Do octopuses, squid and crabs have emotions?

Sciencedaily.com 

Octopuses can solve complex puzzles and show a preference for different individuals, but whether they, and other animals and invertebrates, have emotions is being hotly debated and could shake up humans' moral decision-making, says an expert in animal minds. Most countries don't recognize invertebrates, such as octopuses, crabs, lobsters and crayfish, as sentient beings that can feel pain, but the United Kingdom is considering amendments to its animal welfare legislation that would recognize this.

Physicists create extremely compressible 'gas of light'

Sciencedaily.com 

Researchers have created a gas of light particles that can be extremely compressed. Their results confirm the predictions of central theories of quantum physics. The findings could also point the way to new types of sensors that can measure minute forces.

Mechanism that underlies local dopamine release in the brain

Sciencedaily.com 

When we initiate an action in our everyday lives—chasing after a runaway napkin or getting out of the car—the brain releases a chemical messenger called dopamine that helps regulate the brain area that controls this action.

Physicists 'shine' light on inner details and breakup of simple nucleus

Sciencedaily.com 

Scientists have found a new way to 'see' inside the simplest atomic nuclei to better understand the 'glue' that holds the building blocks of matter together. The results come from collisions of photons (particles of light) with deuterons, the simplest atomic nuclei (made of just one proton bound to one neutron). The photons act somewhat like an x-ray beam to provide the first glimpse of how particles called gluons are arranged within the deuteron.

Oscar Predictions: Pete Hammond’s Final Picks In All 23 Categories

Deadline.com 

After several years in which the Academy of Motion Picture Arts and Sciences vacillated between eight or nine Best Picture nominees, Oscar has returned to a set number of 10 films for its top prize. The whole idea of doubling the amount from five to 10 came about in 2010 to encourage voters to select […]
