| Technique reveals the basis for machine-learning systems' decisions Posted: 28 Oct 2016 01:22 PM PDT In recent years, the best-performing systems in artificial-intelligence research have come courtesy of neural networks, which look for patterns in training data that yield useful predictions or classifications. Now researchers present a new way to train neural networks so that they provide not only predictions and classifications but rationales for their decisions.      |
| When it comes to atomic-scale manufacturing, less really is more Posted: 28 Oct 2016 01:21 PM PDT Electrical currents can be now be switched on and off at the smallest conceivable scale enabling a new generation of 'green electronics' with the potential for great impact on the digital economy. |
| A tiny machine: Infinitesimal computing device Posted: 28 Oct 2016 01:20 PM PDT Electrical and computer engineers have developed a design for a functional nanoscale computing device. The concept involves a dense, three-dimensional circuit operating on an unconventional type of logic that could, theoretically, be packed into a block no bigger than 50 nanometers on any side. |
| See how Arctic sea ice is losing its bulwark against warming summers Posted: 28 Oct 2016 01:19 PM PDT Arctic sea ice, the vast sheath of frozen seawater floating on the Arctic Ocean and its neighboring seas, has been hit with a double whammy over the past decades: as its extent shrunk, the oldest and thickest ice has either thinned or melted away, leaving the sea ice cap more vulnerable to the warming ocean and atmosphere. |
| Treadmill running with heavier shoes tied to slower race times Posted: 28 Oct 2016 01:18 PM PDT It makes sense that running with heavier shoes on will cause you to exert more energy than running with lighter shoes. That was proven several decades ago. But does using more energy while running with heavier shoes translate into slower running times? That's also a yes, say researchers who designed a clever study to show that running times slow when running shoe weight is increased, even if only by a few ounces. |
| Autism spectrum disorder linked to mutations in some mitochondrial DNA Posted: 28 Oct 2016 01:17 PM PDT Children diagnosed with autism spectrum disorder (ASD) have greater numbers of harmful mutations in their mitochondrial DNA than family members, researchers report. |
| Colorado River's dead clams tell tales of carbon emission Posted: 28 Oct 2016 11:21 AM PDT Scientists have begun to account for the topsy-turvy carbon cycle of the Colorado River delta – once a massive green estuary of grassland, marshes and cottonwood, now desiccated dead land. |
| Exploring the evolution of spider venom to improve human health Posted: 28 Oct 2016 06:01 AM PDT More than 46,000 species of spiders creepy crawl across the globe. Each one produces a venom composed of an average of 500 distinct toxins, putting the conservative estimate of unique venom compounds at more than 22 million. Researchers are studying these toxins to increase our understanding of the evolution of spider venom and contribute to the development of new medicines, anti-venoms and research tools. |
| Stability of exhausted T cells limits durability of cancer checkpoint drugs Posted: 27 Oct 2016 11:33 AM PDT Reinvigorating exhausted T cells in mice using a PD-L1 blockade caused very few T memory cells to develop. After the blockade, re-invigorated T cells became re-exhausted if antigen from the virus remained high, and failed to become memory T cells when the virus was cleared, report scientists. |

| Treadmill running with heavier shoes tied to slower race times Posted: 28 Oct 2016 01:18 PM PDT It makes sense that running with heavier shoes on will cause you to exert more energy than running with lighter shoes. That was proven several decades ago. But does using more energy while running with heavier shoes translate into slower running times? That's also a yes, say researchers who designed a clever study to show that running times slow when running shoe weight is increased, even if only by a few ounces. |
| Pop-culture news helped destigmatize out-of-wedlock childbirth Posted: 28 Oct 2016 11:21 AM PDT Celebrity news reports over the past four decades appear to have contributed to the changing makeup of the traditional American family by helping to destigmatize out-of-wedlock childbirths in the United States, according to a study. |
| With cancer genome sequencing, be your own control Posted: 28 Oct 2016 08:53 AM PDT When a researcher found more than 1,000 genetic translocations in her mouse model of B cell lymphoma, she assumed her lab had made a mistake. To rule out experimental technique as the cause of the way-more-than-expected genomic alterations, the lab sequenced three different types of cells from "wildtype" mice - effectively the kind that might move into your garage in bad weather. Like the lymphoma cells before them, the cells from wildtype mice also had over a 1,000 translocations. |

| 3-D tumors grown in the lab provide new perspective for cancer drug discovery Posted: 27 Oct 2016 09:35 AM PDT Understanding how cells within tumors respond to drugs is a critical issue in anticancer drug development. In a new article, researchers report a new approach to study cancer cells' reactions to treatments and present how it can be used to find new promising drug combinations. |
| Could apps be the answer to self-managing diabetes? Posted: 27 Oct 2016 08:52 AM PDT Smart phone apps could offer patients with type 2 diabetes a highly effective method of self-managing their condition, concludes a new study. |
| Better, faster ways of searching for antibiotics Posted: 27 Oct 2016 08:52 AM PDT Antibiotic-resistant bacteria are a major problem worldwide. Scientists explored innovative methods of developing new antibiotics more simply and more easily. |
