Astronomy & Space news

Astronomers detect hydrogen corona of Jupiter's moon Europa

(Phys.org)—Using the Hubble Space Telescope (HST), astronomers have spotted an atomic hydrogen corona around Jupiter's icy moon Europa. The discovery which could improve our understanding of Europa's tenuous atmosphere was published Jan. 13 in the Astronomical Journal.

Fermi sees gamma rays from 'hidden' solar flares

An international science team says NASA's Fermi Gamma-ray Space Telescope has observed high-energy light from solar eruptions located on the far side of the sun, which should block direct light from these events. This apparent paradox is providing solar scientists with a unique tool for exploring how charged particles are accelerated to nearly the speed of light and move across the sun during solar flares.

Radio weak blazars

A blazar is a galaxy whose central nucleus is bright at wavelengths from the low energy radio band to high energy gamma rays (each gamma ray photon is over a hundred million times more energetic than the X-rays seen by the Chandra X-ray Observatory). Astronomers think that the blazar nucleus contains a supermassive black hole, similar to a quasar nucleus. The emission results when matter falls onto the vicinity of the black hole and erupts into powerful, narrow jets of radiating charged particles moving close to the speed of light. Two defining characteristics of blazars, strong radio emission and high variability, are results of the accretion and jets.

Both push and pull drive our galaxy's race through space

Although we can't feel it, we're in constant motion: the earth spins on its axis at about 1,600 km/h; it orbits around the sun at about 100,000 km/h; the sun orbits our Milky Way galaxy at about 850,000 km/h; and the Milky Way galaxy and its companion galaxy Andromeda are moving with respect to the expanding universe at roughly 2 million km/h (630 km per second). But what is propelling the Milky Way's race through space?

Cosmic dust that formed our planets traced to giant stars

Scientists have identified the origin of key stardust grains present in the dust cloud from which the planets in our Solar System formed, a study suggests.

Fermi Gamma-ray Space Telescope discovers the most extreme blazars yet

NASA's Fermi Gamma-ray Space Telescope has identified the farthest gamma-ray blazars, a type of galaxy whose intense emissions are powered by supersized black holes. Light from the most distant object began its journey to us when the universe was 1.4 billion years old, or nearly 10 percent of its present age.

The Outer Space Treaty has been remarkably successful – but is it fit for the modern age?

Space exploration is governed by a complex series of international treaties and agreements which have been in place for years. The first and probably most important of them celebrates its 50th anniversary on January 27 – The Outer Space Treaty. This treaty, which was signed in 1967, was agreed through the United Nations, and today it remain as the "constitution" of outer space. It has been signed and made official, or ratified, by 105 countries across the world.

A proposal for Juno to observe the volcanoes of Io

Jupiter may be the largest planet in the solar system with a diameter 11 times that of Earth, but it pales in comparison to its own magnetosphere. The planet's magnetic domain extends sunward at least 3 million miles (5 million km) and on the back side all the way to Saturn for a total of 407 million miles or more than 400 times the size of the sun.

Four-planet system directly imaged in motion

Located about 129 light years from Earth in the direction of the Pegasus constellation is the relatively young star system of HR 8799. Beginning in 2008, four orbiting exoplanets were discovered in this system which – alongside the exoplanet Formalhaut b – were the very first to be confirmed using the direct imaging technique. And over time, astronomer have come to believe that these four planets are in resonance with each other.

Deciphering the emergence of neuronal diversity

The development of the cerebral cortex played a major role in the evolution of mankind. Scientists are now studying the emergence of its cellular microstructure with high resolution methods. Neuroscientists at the University of Geneva (UNIGE), Switzerland, have analysed the diversity of cortical neurons—more precisely, inhibitory interneurons—during the developmental period before birth. They have discovered the emergence of three main sub-groups of interneurons by decoding the expression of cell-type specific genes as well as their exact location in the cortex. These results, which were published in Nature Communications, will open the door to a more accurate understanding of the complex cell-type specific mechanisms underlying neuro-developmental disorders such as autism and schizophrenia. This should help researchers to discover how psychiatric-related genetic disturbances impact the emergence of neuronal sub-types and how to design novel cell-type specific interventions.

Researchers find Zika virus replicates in placental trophoblasts, could have implications for early prenatal diagnosis

Why is there a delay between when a pregnant woman is infected with Zika virus and when her fetus shows signs of brain malformations or microcephaly? Why do only a small minority of infants born to infected women appear to be affected by Zika virus infection? Researchers at Baylor College of Medicine may have found answers to these important questions through their discovery that the trophoblast cells of the placenta may serve as a potential reservoir, or portal, of fetal transmission of the virus. The trophoblasts are a self-renewing population of cells that support the developing fetus. The findings, appearing today in the journal Scientific Reports, lend hope to the possibility that in the future care providers could use existing prenatal diagnostic techniques to detect the virus in the placental cells and someday find a way to stop its spread to the fetus.

Soldiering on with PTSD

It was late 2012 and I was commanding an infantry company in Kandahar. At night, when we came back from foot patrols, five of us would build a small fire in the corner of the outpost. We'd light scraps of wood inside half of a rusty metal drum and line rickety benches around the braids of flame. Sometimes we talked about missions, smoked cigars and laughed with each other to the point of tears. Other times we quietly listened to the crackle of the wood, each man consumed in his thoughts, hoping the fire would never go out. In those times, I thought of the men who weren't there.

The attraction effect: How our brains can be influenced

The decisions we make are influenced by other possibilities that we did not choose. At the same time, the options we missed out on determine our satisfaction with the outcomes of situations we were unable to control. Psychologists from the University of Basel conducted two experiments: first, they studied the decision-making behavior of students and, second, they measured brain activity and satisfaction when a set of possibilities is supplemented with another alternative. The Journal of Neuroscience has published the results.

Study tallies extra calories Americans consume in their coffee, tea

More than 160 million people in the U.S. drink coffee or tea on a regular basis, and many of them use sugar, cream, flavored syrups or other calorie-laden additives in their drinks of choice. A new analysis reveals just how much Americans are adding to their caloric intake by spicing up or sweetening their coffee or tea.

Epigenetic diversity in childhood cancer

Tumors of the elderly, such as breast cancer and colon cancer, accumulate thousands of DNA mutations. These genetic defects contribute to cancer-specific properties including uncontrolled growth, invasion in neighboring tissues, and evasion from the immune system. Similar properties are also found in childhood cancers, although those tumors carry much fewer genetic defects, making it difficult to explain their clinical heterogeneity.

Misdiagnosed foot, ankle injuries may result in arthritis, chronic pain and disability

A new study among more than 1000 colorectal cancer patients at Dana-Farber Cancer Institute has revealed that a surprising number of patients, about 10% in total, show mutations in genes thought to increase the susceptibility to cancers. The research suggests an expanded role for genetic testing of inherited risk, both to help in treating people with the disease and in preventing their at-risk family members from developing it.

Posttraumatic stress and alcohol use disorders hit American-Indian and Alaskan-Native men the hardest

Posttraumatic stress disorder (PTSD) can develop after a traumatic event or events. Although it is most often associated with military personnel exposed to the trauma of combat, it can also disproportionately affect vulnerable American Indian and Alaskan-Native (AI/AN) populations. Because alcohol use disorders (AUDs) also have a disproportionate impact on AI/ANs, this study compared both lifetime PTSD and past-year AUD among AI/ANs and non-Hispanic Whites (NHWs).

Exploring the Victorian fear of cats

The EU-funded DISEASES project has been exploring how the Victorians diagnosed, understood and dealt with many of the phenomena related to stress and overload that characterise today's modern globalised society. One intriguing discovery has been on the Victorian emphasis on phobias, particularly ailurophobia – the fear of cats.

Newborn screening for severe immunodeficiency: Advantage in the case of early treatment

The German Institute for Quality and Efficiency in Health Care (IQWiG) assessed the benefit of newborn screening for severe combined immunodeficiency (SCID). Without treatment most young children with SCID die within 1 to 2 years, as their immune response fails.

Recent upsurge of A(H7N9) cases in China, updated ECDC rapid risk assessment

A steep increase of human cases of avian influenza A(H7N9) has been reported since the beginning of December 2016 from China. During this wave, the number of human cases is already higher than during the last two waves in 2014-15 and 2015-16. The majority of recently reported human cases are associated with exposure to infected live poultry or contaminated environments, including markets where live poultry are sold. Influenza A(H7N9) viruses continue to be detected in poultry and their environments in the areas where human cases are occurring. In addition, the human cases are more geographically widespread and cases are also reported from rural areas, unlike in previous epidemics.

Silencing cancer cell communication may reduce the growth of tumors

In several types of cancer, elevated expression of the chemokine receptor CCR4 in tumors is associated with poor patient outcomes. Communication through CCR4 may be one mechanism that cancer cells use to create a pro-tumor environment that protects tumors from immune system attacks. Antibodies that block CCR4 are currently in clinical trials for treating blood and lymphatic cancers, but these approaches may also effectively target cancers that produce solid tumors.

Time-pressed physicians spend significantly more time on computer than on direct patient interaction

Internal medicine physicians at a Swiss teaching hospital frequently worked overtime and spent about 3 times as much time using a computer as they did on patients. Most of their time at work was spent on activities indirectly related to patient care. Results of the time and motion study are published in Annals of Internal Medicine.

Penn/CHOP study helps inform interventions for global road traffic injury crisis

Road traffic injuries are a major cause of disability and are responsible for more than one million deaths each year throughout the world. A disproportionate number of road traffic injuries occur in countries with rapidly developing economies where increases in mobility and motor vehicle use are not often matched with safety-focused infrastructure and road safety policy enforcement. This constitutes a global public health crisis that requires a multisector and dynamic response strategy. An important, though nontraditional, public health partner may be multinational corporations that strive to protect and promote health in their global workforces.

New study looks at LGBT allies in college sports

Plant regulatory proteins 'tagged' with sugar

New work from Carnegie's Shouling Xu and Zhiyong Wang reveals that the process of synthesizing many important master proteins in plants involves extensive modification, or "tagging" by sugars after the protein is assembled. Their work uncovers both similarity and distinction between plants and animals in their use of this protein modification. It is published by Proceedings of the National Academy of Sciences.

Blocking critical enzyme helps to mitigate diseases associated with protein folding and lipid stress

In the ancient Japanese art of origami, paper must be folded precisely and following a specific order to create the desired result—say, a crane or lotus flower. It's a complex pursuit that requires keen attention to detail and utmost accuracy.

Viral protein transforms as it measures out DNA

To generate swarms of new viral particles, a virus hijacks a cell into producing masses of self-assembling cages that are then loaded with the genetic blueprint for the next infection. But the picture of how that DNA is loaded into those viral cages, or capsids, was blurry, especially for two of the most common types of DNA virus on earth, bacterial viruses and human herpesvirus. Jefferson researchers pieced together the three-dimensional atomic structure of a doughnut-shaped protein that acts like a door or 'portal' for the DNA to get in and out of the capsid, and have now discovered that this protein begins to transform its structure when it comes into contact with DNA. Their work published today in Nature Communications.

Study says grass carp have invaded three of the Great Lakes

Invasive grass carp have reached three of the Great Lakes and pose a significant environmental risk there, but time remains to prevent them from getting out of hand, according to a scientific analysis released Friday.

Researchers study wolf parasites

Since the year 2000, the Eurasian grey wolf, Canis lupus lupus, has spread across Germany. Ines Lesniak, doctoral student at the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), and her colleagues, have taken a closer look at the parasites of this returnee to determine whether the number and species of parasites change with an increasing wolf population. This was the case, because the number of parasite species per individual wolf increased as the wolf population expanded. Furthermore, cubs had a higher diversity of parasite species than older animals. The good news: wolf parasites do not pose a threat to human health. The results of this study were published in the scientific online journal Scientific Reports.

Searching for young lake sturgeon near Detroit-area spawning reefs

Construction crews recently deposited 25,000 tons of limestone blocks on the bottom of the Detroit River in the latest phase of a decade-plus effort to lure lake sturgeon to rock spawning reefs and help restore severely depleted populations of the once-common Great Lakes giants.

Fish show cheating can be better than playing by the rules in the mating game

The males of some species go to extraordinary lengths to attract females – but some simply cheat. Take African cichlid fish. Many males build underwater "sandcastle" structures that the females use to judge the quality of their potential mates. But, as my colleagues and I found out during a recent study, some males don't bother with this show of construction prowess, and instead are able to father offspring by engaging in "sneaky mating".

Too many Bambi are bad for the forest

Overabundant deer can spell trouble for people, including frequent car collisions and the spread of zoonotic diseases. But deer can also disrupt wildlife communities—such as forest songbirds—by eating away their habitat. In a new study published in Landscape and Urban Planning, researchers show that areas in the eastern U.S. with high deer numbers tend to have fewer birds that need forest shrubs. These species use low-lying foliage to hide their nests from predators and to hunt for insect prey. Unfortunately, these plants are also on the menu of the white-tailed deer.
