Physics news
Researchers show that an iron bar is capable of decision-making(Phys.org)—Decision-making—the ability to choose one path out of several options—is generally considered a cognitive ability possessed by biological systems, but not by physical objects. Now in a new study, researchers have shown that any rigid physical (i.e., non-living) object, such as an iron bar, is capable of decision-making by gaining information from its surroundings accompanied by physical fluctuations. | |
A little light interaction leaves quantum physicists beamingA team of physicists at the University of Toronto (U of T) have taken a step toward making the essential building block of quantum computers out of pure light. Their advance, described in a paper published this week in Nature Physics, has to do with a specific part of computer circuitry known as a "logic gate." | |
Thermometry using an optical nanofiberExperimental quantum physics often resides in the coldest regimes found in the universe, where the lack of large thermal disturbances allows quantum effects to flourish. A key ingredient to these experiments is being able to measure just how cold the system of interest is. Laboratories that produce ultracold gas clouds have a simple and reliable method to do this: take pictures! | |
Large Hadron Collider progresses toward higher intensitiesAs with any particle accelerator designed to explore a new energy frontier, the operators at the Large Hadron Collider (LHC) have to take the machine up to its full operating potential step by step. Following the start of Run 2 at a new record energy in June, the LHC had delivered some 28,000 billion collisions to the large experiments by mid-August. Now it is on its way towards much faster delivery, as the operators work on progressively increasing the intensity of the proton beams in the machine. | |
Record high pressure squeezes secrets out of osmiumAn international team of scientists led by the University of Bayreuth and with participation of DESY has created the highest static pressure ever achieved in a lab: Using a special high pressure device, the researchers investigated the behaviour of the metal osmium at pressures of up to 770 Gigapascals (GPa) - more than twice the pressure in the inner core of the Earth, and about 130 Gigapascals higher than the previous world record set by members of the same team. Surprisingly, osmium does not change its crystal structure even at the highest pressures, but the core electrons of the atoms come so close to each other that they can interact - contrary to what is usually known in chemistry. | |
Researchers provide experimental foundation for optical computingSomeday, our computers, nanoantennas and other kinds of equipment may operate on the basis of photons rather than electrons. Even now, researchers are preparing to accomplish this technological switch. An international group of Russian, French and Spanish scientists have made a contribution toward the elementary components of new photonic devices. The results of their study have been published in the latest issue of Scientific Reports. | |

Credit scheme backfired, hiking greenhouse gases, study findsA global scheme meant to keep atmospheric greenhouse gas (GHG) levels in check instead caused some 600 million tonnes of excess emissions, researchers said Monday. | |
Boaters mapping Pacific garbage arrive in San FranciscoFar away from California's coast, where the Pacific Ocean currents swirl, the blue of the sea was replaced by fishing nets, buckets, buoys, laundry baskets and unidentifiable pieces of plastic that floated past the Ocean Starr, a ship carrying a team of scientists and volunteers gathering data on plastic garbage. | |
Fastest moving glacier in the world sheds 12.5 sq km chunk of iceSatellite images show that the fastest moving glacier in the world shed a chunk of ice measuring around 12.5 sq km this week – one of the most significant calving events on record. | |
Trading program linked to significant emissions reductionsThe emissions trading program in the northeastern U.S. to limit carbon dioxide emissions from the electric power sector is responsible for about half the region's emissions reductions – an amount far greater than reductions achieved in the rest of the country, according to a Duke University-led study. | |
Tree rings on Hawai'i could hold new knowledge about El NinoTrees can record centuries of history in their rings – changes in rainfall and temperatures, even evidence of fires sweeping through a region or the climatic impacts of volcanic eruptions. Annual rings are common in trees that experience seasonal climate variability and dormancy, but in the tropics, these records are rare. Now, for the first time, scientists have documented consistent annual tree rings in a native species on Hawai'i. | |
Climate surprises possibly in store for Antarctica, say researchersTwo different climate scenarios appear plausible for Antarctica in the 21st century, says Paul Mayewski, director of the Climate Change Institute at the University of Maine. | |

Self-healing landscape: Landslides after earthquakesIn mountainous regions earthquakes often cause strong landslides, which can be exacerbated by heavy rain. However, after an initial increase, the frequency of these mass wasting events, often enormous and dangerous, declines, in fact independently of meteorological events and aftershocks. These new findings are presented by a German-Franco-Japanese team of geoscientists in the current issue of the journal Geology, under the lead of the GFZ German Research Centre for Geosciences. Even after strong earthquake the activity of landslides returns back over the course of one to four years to the background level before the earthquake. | |

NASA is laser-focused on deep space communicationToday's technology has all but eliminated time delays in telecommunication on Earth, but when they do occur they can be frustrating, especially when trying to communicate complex or time sensitive information. The same type of delay could happen when communicating with spacecraft and crew members in deep space on the journey to Mars. For example, communication over radio waves could have round-trip delays of up to 31 minutes at Mars. According to a recent investigation, this could impact team performance and emotional well-being. | |

Water, water, everywhere – where to drink in the solar systemScience fiction movies about aliens threatening the Earth routinely ascribe them the motive of coming here to steal our resources, most often our water. This is ill thought-out, as water is actually extremely common. Any civilisation coming to our solar system in need of water (either to drink or to make rocket fuel) would be foolish to plunge all the way inwards to the Earth, from where they'd have to haul their booty back against the pull of the sun's gravity. | |
What is the asteroid belt?In the 18th century, observations made of all the known planets (Mercury, Venus, Earth, Mars, Jupiter and Saturn) led astronomers to discern a pattern in their orbits. Eventually, this led to the Titius–Bode law, which predicted the amount of space between the planets. In accordance with this law, there appeared to be a discernible gap between the orbits of Mars and Jupiter, and investigation into it led to a major discovery. | |
SDO: Images of a mid-level solar flareThe sun emitted a mid-level solar flare, peaking at 3:33 a.m EDT on Aug. 24, 2015. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however—when intense enough—they can disturb the atmosphere in the layer where GPS and communications signals travel. | |

Food intake, a fragile balance between neural pathwaysA team at the Laboratoire biologie fonctionnelle et adaptative (CNRS/Université Paris Diderot) investigated the relative role of energy needs and "pleasure" of eating in food intake. The researchers studied a group of neurons in mice. They observed that when the neuron activity is compromised, feeding behavior becomes less related to the body's metabolic needs and more dependent on food palatability. These results could explain how ever easier access to appetizing foods may contribute to compulsive eating disorders and favor obesity. This work has just been published in Cell Metabolism. | |
Activated neurons produce protective protein against neurodegenerative conditionsActivated neurons produce a protein that protects against nerve cell death. Prof. Dr. Hilmar Bading and his group at Heidelberg University's Interdisciplinary Center for Neurosciences have found out how this effect comes about and defined a crucial player. "We already knew that brain activity promotes neuroprotection," Prof. Bading says. "Now we have discovered a central mechanism for this process and a key molecule produced by the body to develop a neuroprotective shield." These results have been published in Cell Reports. | |

Study links physical activity to greater mental flexibility in older adultsOne day soon, doctors may determine how physically active you are simply by imaging your brain. Physically fit people tend to have larger brain volumes and more intact white matter than their less-fit peers. Now a new study reveals that older adults who regularly engage in moderate to vigorous physical activity have more variable brain activity at rest than those who don't. This variability is associated with better cognitive performance, researchers say. | |
Giving pharmacists the power to combat opioid overdosesIn response to the growing opioid crisis, several states, including Massachusetts and Rhode Island, have granted pharmacists the authority to provide naloxone rescue kits without a prescription to at-risk patients.

Humans carry more antibiotic-resistant bacteria than animals they work withAntibiotic-resistant bacteria are a concern for the health and well-being of both humans and farm animals. One of the most common and costly diseases faced by the dairy industry is bovine mastitis, a potentially fatal bacterial inflammation of the mammary gland (IMI). Widespread use of antibiotics to treat the disease is often blamed for generating antibiotic-resistant bacteria. However, researchers investigating staphylococcal populations responsible for causing mastitis in dairy cows in South Africa found that humans carried more antibiotic-resistant staphylococci than the farm animals with which they worked. The research is published in the Journal of Dairy Science. | |
Medical terms lead to divide between parents and doctorsFew things are more stressful than dealing with a sick child. From discussing treatment with a pediatrician to complying with day care policies, a parent must consider many factors when making a decision about their child's health. Now, a recent study from the University of Missouri and the University of Michigan is shedding light on the significant divide that can exist between patients and physicians about the same terminology—especially when it comes to discussing "pink eye," a particular flashpoint in childcare. | |

Enjoyment motivates people to participate in the sharing economyPeople are motivated to participate in the sharing economy because of its ecological sustainability, the enjoyment derived from the activity, the sense of community, and saving money and time. Ecological sustainability is one of the basic principles of the sharing economy - not to purchase everything individually but rather consumer collaboratively by sharing goods and services. Another canonical principle of the sharing economy is 'paying it forward'. However, collaborative consumption may involve the same hurdles as any other type of green consumption, researcher from the Finnish Aalto University have found in a recently published study. | |
