Model suggests how early dark energy could resolve the Hubble tensionThe universe is continuously expanding, yet the exact rate at which it does so remains unclear, and has so far only been approximated using NASA's Hubble Space Telescope and other similar instruments. Moreover, in recent years, astronomers using the Hubble telescope have unveiled a discrepancy between the two primary techniques used for estimating the universe's expansion rate. | |
Astronomers detect 130 short period variable starsBy conducting photometric observations of the open cluster Stock 8 and its surrounding region, astronomers have identified 130 short-period variable stars, classifying 51 of them as members of the cluster. A paper detailing the findings appeared June 18 on the arXiv pre-print repository. | |
Curiosity Rover finds high levels of methane on MarsA team working with NASA to study data the Mars Curiosity Rover has found high levels of methane at a site on the Red Planet. The existence of methane is, of course, a possible sign of life, since it is produced in abundance by microorganisms here on Earth. | |
The low density of some exoplanets is confirmedThe Kepler mission and its extension, called K2, discovered thousands of exoplanets. It detected them using the transit technique, measuring the dip in light intensity whenever an orbiting planet moved across the face of its host star as viewed from Earth. Transits can not only measure the orbital period, they often can determine the size of the exoplanet from the detailed depth and shape of its transit curve and the host star's properties. The transit method, however, does not measure the mass of the planet. The radial velocity method, by contrast, which measures the wobble of a host star under the gravitational pull of an orbiting exoplanet, allows for the measurement of its mass. Knowing a planet's radius and mass allows for the determination of its average density, and hence clues to its composition. | |
Subaru Telescope identifies the outermost edge of the Milky Way systemA team of researchers identified the outermost edge of the Milky Way galaxy. Using the Subaru Telescope, the researchers examined the boundary of the stellar system that makes up the galaxy. The ultimate size of the galaxy is 520,000 light years in radius, 20 times larger than the distance between the galactic center and our solar system (26,000 light years) (Figure 1). Stars that reach these outermost regions of the galaxy during their orbital motions are ancient stellar populations with ages as old as 12 billion years. The spatial extent in which these ancient stars wander is, therefore, important for understanding the Milky Way's formation. | |
'Bathtub rings' around Titan's lakes might be made of alien crystalsThe frigid lakeshores of Saturn's moon Titan might be encrusted with strange, unearthly minerals, according to new research being presented here. | |
Smash and grab: A heavyweight stellar champion for dying starsDying stars that cast off their outer envelopes to form the beautiful yet enigmatic "planetary nebulae" (PNe) have a new heavy-weight champion, the innocuously named PNe BMP1613-5406. Massive stars live fast and die young, exploding as powerful supernovae after only a few million years. However, the vast majority of stars, including our own sun, have much lower mass and may live for many billions of years before going through a short lived but glorious PNe phase. PNe form when only a tiny fraction of unburnt hydrogen remains in the stellar core. Radiation pressure expels much of this material and the hot stellar core can shine through. This ionizes the previously ejected shroud creating a PNe and providing a visible and valuable fossil record of the stellar mass loss process (PNe have nothing to do with planets but acquired this name because their glowing spheres of ionized gas around their hot central stars resembled planets to early observers). | |
Galaxy clusters caught in a first kissFor the first time, astronomers have found two giant clusters of galaxies that are just about to collide. This observation can be seen as a missing 'piece of the puzzle' in our understanding of the formation of structure in the universe, since large-scale structures—such as galaxies and clusters of galaxies—are thought to grow by collisions and mergers. The result was published in Nature Astronomy. | |

Robots may care for you in old age—and your children will teach themIt's likely that before too long, robots will be in the home to care for older people and help them live independently. To do that, they'll need to learn how to do all the little jobs that we might be able to do without thinking. Many modern AI systems are trained to perform specific tasks by analysing thousands of annotated images of the action being performed. While these techniques are helping to solve increasingly complex problems, they still focus on very specific tasks and require lots of time and processing power to train. | |

A wearable vibration sensor for accurate voice recognitionA voice-recognition feature can be easily found on mobile phones these days. Oftentimes, we experience an incident where a speech recognition application is activated in the middle of a meeting or a conversation in the office. Sometimes, it is not activated at all regardless of numbers of times we call out the application. It is because a mobile phone uses a microphone which detects sound pressure to recognize voice, and it is easily affected by surrounding noise and other obstacles. | |

New therapy targets gut bacteria to prevent and reverse food allergiesEvery three minutes, a food-related allergic reaction sends someone to the emergency room in the U.S. Currently, the only way to prevent a reaction is for people with food allergies to completely avoid the food to which they are allergic. Researchers are actively seeking new treatments to prevent or reverse food allergies in patients. Recent insights about the microbiome—the complex ecosystem of microorganisms that live in the gut and other body sites—have suggested that an altered gut microbiome may play a pivotal role in the development of food allergies. A new study, led by investigators from Brigham and Women's Hospital and Boston Children's Hospital, identifies the species of bacteria in the human infant gut that protect against food allergies, finding changes associated with the development of food allergies and an altered immune response. In preclinical studies in a mouse model of food allergy, the team found that giving an enriched oral formulation of five or six species of bacteria found in the human gut protected against food allergies and reversed established disease by reinforcing tolerance of food allergens. The team's results are published in Nature Medicine. | |
Settling the debate on serotonin's role in sleepSerotonin is a multipurpose molecule found throughout the brain, playing a role in memory, cognition, and feelings of happiness and other emotions. In particular, researchers have long debated serotonin's role in sleep: Does serotonin promote sleep, or its opposite, wakefulness? | |
Non-invasive, more precise preimplantation genetic test under development for IVF embryosSelecting the best possible embryo to implant in a woman undergoing in vitro fertilization (IVF) is a complicated task. As success rates for IVF have improved, many clinics now implant a single embryo during an IVF cycle—with the goal of avoiding a multiple pregnancy—and the responsibility of selecting the embryo falls to the embryologist. To determine the quality and viability of an embryo, embryologists typically examine specific features of the embryos using a light microscope. In addition, specialists can use data from preimplantation genetic testing for aneuploidy (PGT-A), a test of whether cells from the embryo at the blastocyst stage have a normal or abnormal number of chromosomes. However, this crucial test carries the risk of false positives (which could lead to discarding a normal embryo) and false negatives (which could lead to transferring an embryo with a chromosomal abnormality). | |
Solving the cochlea: First complete virtual model of ear's speech sensorUntil now, the part of the ear that processes speech was poorly reflected in computer models, but University of Michigan researchers have figured out the math that describes how it works—which could help improve hearing tests and devices that restore some hearing to the deaf. | |

Immunotherapy and HDAC inhibition are anti-cancer bestiesImmunotherapies have revolutionized the care of many cancers, teaching the body's own immune cells to recognize and attack tumor cells. Leading the way are drugs known as checkpoint inhibitors, which block a kind of "white flag" that tumors wave as a peace signal to T cells that would very much like to kill them. Really, this white flag is a protein called PD-L1—many tumors coat themselves in it. When PD-L1 on the surface of a cancer cell sees its partner, PD1, on T cells, these T cells are tricked into letting the cancer cell live. To counteract this dirty trick, checkpoint inhibitor drugs block the functions of PD-L1 on tumor cells (e.g. atezolizumab) or PD1 on T cells (e.g. pembrolizumab), allowing T cells to go about their cancer-killing business. | |
Physical evidence in the brain for types of schizophreniaIn a study using brain tissue from deceased human donors, Johns Hopkins Medicine researchers say they found new evidence that schizophrenia can be marked by the buildup of abnormal proteins similar to those found in the brains of people with such neurodegenerative disorders as Alzheimer's or Huntington's diseases. | |

Does stimulation of the brain's dorsal anterior insula trigger ecstasy?The epileptic "aura" is a subjective phenomenon that sometimes precedes the visible clinical features of a seizure. Investigators tested three epileptic patients prior to potential surgery to try to determine where their seizures originate. They observed that these patients reported an ecstatic aura only when the dorsal anterior insula of the brain was stimulated. Their findings in the journal Brain Stimulation, published by Elsevier, provide additional support of a major role played by the dorsal anterior insula in ecstatic experiences. | |

Understanding brain activity when you name what you seeYou see an object, you think of its name and then you say it. This apparently simple activity engages a set of brain regions that must interact with each other to produce the behavior quickly and accurately. A report published in eNeuro shows that a reliable sequence of neural interactions occurs in the human brain that corresponds to the visual processing stage, the language state when we think of the name, and finally the articulation state when we say the name. The study reveals that the neural processing does not involve just a sequence of different brain regions, but instead it engages a sequence of changing interactions between those brain regions. | |

Molecular scissors stabilize the cell's cytoskeletonResearchers at the Paul Scherrer Institute PSI in Villigen, Switzerland, have for the first time elucidated the structure of important enzymes in human cells that alter essential building blocks of the cellular cytoskeleton. This reveals the missing part of a cycle that regulates the build-up or breakdown of supporting elements of the cell. The enzymes investigated work as molecular scissors and can be involved in the development of diseases, for example, cancer and diseases of the nervous system. Their structural elucidation provides approaches for the development of specific inhibitors and perhaps new therapies. The researchers gained detailed insights into the structure of the enzymes with the help of the Swiss Light Source SLS. They have now published their results in the journal Nature Structural & Molecular Biology. | |
