Owners of thoroughbred stallions carefully breed prizewinning horses over generations to eke out fractions of a second in million-dollar races. Materials scientists have taken a page from that playbook, turning to the power of evolution and artificial selection to develop superconductors that can transmit electric current as efficiently as possible.

Short-term use of opioids increases subjective pleasure
The human opioid system contributes to the regulation of emotions, pleasure and pain. Opioids are strong analgesics. In addition to effectively relieving pain, external opioids may improve mood and reduce negative emotions. However, not much has been known about the effect of opioids on emotional responses caused by external stimuli.

This robot helps you lift objects—by looking at your biceps
We humans are very good at collaboration. For instance, when two people work together to carry a heavy object like a table or a sofa, they tend to instinctively coordinate their motions, constantly recalibrating to make sure their hands are at the same height as the other person's. Our natural ability to make these types of adjustments allows us to collaborate on tasks big and small.

New approaches to study the genetics of autism spectrum disorder may lead to new therapies
Canadian neuroscientists are using novel experimental approaches to understand autism spectrum disorder, from studying multiple variation in a single gene to the investigation of networks of interacting genes to find new treatments for the disorder.

CycleMatch: a new approach for matching images and text
Researchers at Leiden University and the National University of Defense Technology (NUDT), in China, have recently developed a new approach for image-text matching, called CycleMatch. Their approach, presented in a paper published in Elsevier's Pattern Recognition journal, is based on cycle-consistent learning, a technique that is sometimes used to train artificial neural networks on image-to-image translation tasks. The general idea behind cycle-consistency is that when transforming source data into target data and then vice versa, one should finally obtain the original source samples.

Engineered bacteria could be missing link in energy storage
One of the big issues with sustainable energy systems is how to store electricity that's generated from wind, solar and waves. At present, no existing technology provides large-scale storage and energy retrieval for sustainable energy at a low financial and environmental cost.

Sea dragons captivate visitors at California aquarium
At first glance, it looks like a branch of kelp, but then an eye moves among its leafy appendages, and ridges of tiny, translucent fins start to flutter, sending the creature gliding through the water like something from a fairy tale.

World celebrates centenary of confirmation of relativity
Celebrations are underway across the globe to commemorate 100 years since a UK-led expedition confirmed Einstein's general theory of relativity. The theory fundamentally changed our understanding of physics and astronomy, and underpins critical modern technologies such as the satellite-based Global Positioning System (GPS). A series of public events in the UK and around the world will mark this seminal anniversary.

Comet inspires chemistry for making breathable oxygen on Mars
Science fiction stories are chock full of terraforming schemes and oxygen generators for a very good reason—we humans need molecular oxygen (O2) to breathe, and space is essentially devoid of it. Even on other planets with thick atmospheres, O2 is hard to come by.

100% renewables doesn't equal zero-carbon energy, and the difference is growing
While 160 companies around the world have committed to use "100 percent renewable energy," that does not mean "100 percent carbon-free energy." The difference will grow as power grids become less reliant on fossil power, according to a new Stanford study published today in Joule. Entities committed to fighting climate change can and should measure the environmental benefits of their renewable strategies accurately, the authors write.
