Astronomy & Space news
![]() | Water-worlds are common: Exoplanets may contain vast amounts of waterScientists have shown that water is likely to be a major component of those exoplanets (planets orbiting other stars) which are between two to four times the size of Earth. It will have implications for the search of life in our Galaxy. The work is presented at the Goldschmidt Conference in Boston. |
![]() | Another way for stellar-mass black holes to grow largerA trio of researchers with The University of Hong Kong, Academia Sinica Institute of Astronomy and Astrophysics in Taiwan and Northwestern University in the U.S., has come up with an alternative theory to explain how some stellar-mass black holes can grow bigger than others. In their paper published in The Astrophysical Journal Letters, Shu-Xu Yi, K.S. Cheng and Ronald Taam describe their theory and how it might work. |
![]() | Magnetized inflow accreting to center of Milky Way galaxyAre magnetic fields an important guiding force for gas accreting to a supermassive black hole (SMBH) like the one that our Milky Way galaxy hosts? The role of magnetic fields in gas accretion is little understood, and trying to observe it has been challenging to astronomers. Researchers at the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA), Taiwan, led by Dr. Pei-Ying Hsieh, have obtained a good measurement by using the instruments on the James Clerk Maxwell Telescope (JCMT). Their result provides clear evidence that the orientation of the magnetic field is in alignment with the molecular torus and ionized streamers rotating with respect to Sagittarius A*—the black hole at the center of the Milky Way. The findings are published in Astrophysical Journal in 2018 August. |
![]() | Six things about Opportunity's recovery effortsNASA's Opportunity rover has been silent since June 10, when a planet-encircling dust storm cut off solar power for the nearly-15-year-old rover. Now that scientists think the global dust storm is "decaying"—meaning more dust is falling out of the atmosphere than is being raised back into it—skies might soon clear enough for the solar-powered rover to recharge and attempt to "phone home." |
![]() | Lockheed Martin gives first look into where astronauts may live on missions to deep spaceA massive cylindrical habitat may one day house up to four astronauts as they make the trek to deep space. |
![]() | First science with ALMA's highest-frequency capabilitiesThe ALMA telescope in Chile has transformed how we see the universe, showing us otherwise invisible parts of the cosmos. This array of incredibly precise antennas studies a comparatively high-frequency sliver of radio light: waves that range from a few tenths of a millimeter to several millimeters in length. Recently, scientists pushed ALMA to its limits, harnessing the array's highest-frequency (shortest wavelength) capabilities, which peer into a part of the electromagnetic spectrum that straddles the line between infrared light and radio waves. |
![]() | What is NASA's Heat Melt Compactor?Dealing with trash is a challenge wherever people work and live, and space is no exception. Astronauts produce a couple of pounds of trash per crew member per day. To better manage this, NASA is developing a new trash processing system to demonstrate on the International Space Station. This work is critical for potential future missions traveling farther from Earth, to the moon and Mars, and for longer periods of time. Current modes of trash disposal and waste management will not be available at the extreme durations and distances these missions will require – while the space station is only 250 miles above us in low-Earth orbit, the moon is about 240,000 miles away, and Mars is on average about 140,000,000 miles away! In addition, the new system will give astronauts the ability to recover valuable resources from their trash, an important thing when you have to take everything with you. |
![]() | New telescope chases the mysteries of radio flashes and dark energySouth Africa is becoming one of the world's most important radio astronomy hubs, thanks in large part to its role as co-host of the Square Kilometre Array (SKA). Now a new telescope is being unveiled that will be built at the SKA South Africa site in the Karoo. The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) project is an international collaboration being led by scientists from the University of KwaZulu-Natal. The Conversation Africa chatted to project leader Professor Kavilan Moodley about HIRAX's scientific goals. |

![]() | More efficient security for cloud-based machine learningA novel encryption method devised by MIT researchers secures data used in online neural networks, without dramatically slowing their runtimes. This approach holds promise for using cloud-based neural networks for medical-image analysis and other applications that use sensitive data. |
![]() | New AI camera could revolutionize autonomous vehiclesThe image recognition technology that underlies today's autonomous cars and aerial drones depends on artificial intelligence: the computers essentially teach themselves to recognize objects like a dog, a pedestrian crossing the street or a stopped car. The problem is that the computers running the artificial intelligence algorithms are currently too large and slow for future applications like handheld medical devices. |
![]() | AI could make dodgy lip sync dubbing a thing of the pastResearchers have developed a system using artificial intelligence that can edit the facial expressions of actors to accurately match dubbed voices, saving time and reducing costs for the film industry. It can also be used to correct gaze and head pose in video conferencing, and enables new possibilities for video postproduction and visual effects. |
![]() | Robots as tools and partners in rehabilitationIn future decades, the need for effective strategies for medical rehabilitation will increase significantly, because patients' rate of survival after diseases with severe functional deficits, such as a stroke, will increase. Socially assistive robots (SARs) are already being used in rehabilitation for this reason. In the journal Science Robotics, a research team led by neuroscientist Dr. Philipp Kellmeyer of the Freiburg University Medical Center and Prof. Dr. Oliver Müller from the Department of Philosophy of the University of Freiburg, analyzes the improvements necessary to make SARs valuable and trustworthy assistants for medical therapies. |

![]() | Virtual reality providing real-world literacy and numeracy learning toolVirtual reality is moving beyond purely entertainment to become a potential tool in improving literacy, and the University of Otago is behind one ground-breaking approach. |
![]() | Color effects from transparent 3-D printed nanostructuresMost of the objects we see are colored by pigments, but using pigments has disadvantages: such colors can fade, industrial pigments are often toxic, and certain color effects are impossible to achieve. The natural world, however, also exhibits structural coloration, where the microstructure of an object causes various colors to appear. Peacock feathers, for instance, are pigmented brown, but—because of long hollows within the feathers—reflect the gorgeous, iridescent blues and greens we see and admire. Recent advances in technology have made it practical to fabricate the kind of nanostructures that result in structural coloration, and computer scientists from the Institute of Science and Technology Austria (IST Austria) and the King Abdullah University of Science and Technology (KAUST) have now created a computational tool that automatically creates 3-D-print templates for nanostructures that correspond to user-defined colors. Their work demonstrates the great potential for structural coloring in industry, and opens up possibilities for non-experts to create their own designs. This project will be presented at this year's top computer graphics conference, SIGGRAPH 2018, by first author and IST Austria postdoc Thomas Auzinger. |

![]() | Study confirms truth behind 'Darwin's moth'Scientists have revisited—and confirmed—one of the most famous textbook examples of evolution in action. |
![]() | Bioengineers borrow from electronics industry to get stem cells to shape upTo understand how cells in the body behave, bioengineers create miniature models of the cells' environment in their lab. But recreating this niche environment is incredibly complex in a controlled setting, because researchers are still learning all the factors that influence cell behavior and growth. By observing and then modifying their engineered mini-models, scientists are better able to identify those factors. |
![]() | Newly discovered class of molecules may boost cancer vaccine developmentCancer vaccines are designed to heighten the immune system's awareness of a tumor's unique features, boosting its ability to recognize, attack, and destroy the cancer. To date, effective cancer vaccines have focused on what are called "neoantigens," tumor-specific peptides that result from acquired mutations. But not every tumor produces distinct antigens that the immune system can recognize. As a result, current cancer vaccines don't work for all patients. |
![]() | Are our wild animals growing old gracefully?For most of us, the body's deterioration is an unavoidable part of getting older. This age-related decline, known as "senescence", can occur subtly and slowly for some individuals, while for others it happens much faster. A researcher from The Australian National University is trying to find out why. |
![]() | Pigs form a visual concept of human facesContrary to previous studies, pigs appear to have better visual discrimination abilities than had previously been assumed. Cognition researchers from the Messerli Research Institute showed in a new study that pigs not only discriminate between front and back views of human heads but also that the animals apparently use certain facial features such as our eyes or mouth as cues. The results shed a new, more positive light on the previously rather pessimistic opinion of the visuo-cognitive abilities of these clever animals. |

![]() | Why mosquitoes bite some people more than othersSurprisingly few of the more than 3,000 mosquito species actually specialise in biting humans. Instead, most are opportunistic feeders – feeding when they are able and from lots of different sources. But Aedes aegypti and Anopheles gambiae are well known for their preference for human blood and their role as vectors which transmit disease in humans. Ae. aegypti has been linked to zika and dengue, while An. gambiae carries the parasite which causes malaria. |

They combined auxin-inducible "protein knockdown" with a synthetic antibody to not only observe fluorescent proteins in living cells but also to rapidly remove them in a temporally controlled manner. |
![]() | Vietnam's caged bears dying off as bile prices plummetTwo moon bears are gently removed from the cramped cages where they have been held for 13 years, rescuers carefully checking their rotten teeth and matted paws before sending them to their new home in a grassy sanctuary in northern Vietnam. |
![]() | How do plants rest photosynthetic activity at night?Photosynthesis, the process by which plants generate food, is a powerful piece of molecular machinery that needs sunlight to run. The proteins involved in photosynthesis need to be 'on' when they have the sunlight they need to function, but in the dark, when photosynthesis is not possible, they need to idle, like the engine of a car at a traffic light. They do this by a process called 'redox regulation'—the activation and deactivation of proteins via changes in their redox (reduction/oxidation) states. It's well understood that under sunlight, the ferredoxin-thioredoxin reductase (FTR)/thioredoxin (Trx) pathway is responsible for the reduction process, which activates the photosynthetic pathway. However, scientists have long been in the dark about what happens when light is not available, and how plants reset photosynthetic proteins to be ready to function when light is resumed. |
