Hubble views a galactic mega-merger

The subject of this NASA/ESA Hubble Space Telescope image is known as NGC 3597. It is the product of a collision between two good-sized galaxies, and is slowly evolving to become a giant elliptical galaxy. This type of galaxy has grown more and more common as the universe has evolved, with initially small galaxies merging and progressively building up into larger galactic structures over time.

The properties of pre-stellar cores

Stars like the Sun begin their lives as cold, dense cores of dust and gas that collapse under the influence of gravity until nuclear fusion is ignited. These cores contain hundreds to thousands of solar-masses of material and have gas densities about a thousand times greater than typical interstellar regions (the typical value is about one molecule per cubic centimeter). How the collapse process occurs in these embryos in poorly understood, from the number of stars that form to the factors that determine their ultimate masses, as well as the detailed timescale for stellar birth. Material, for example, might simply fall freely to the center of the core, but in most realistic scenarios the infall is inhibited by pressure from warm gas, turbulent motions, magnetic fields, or some combination of them.

Absence of transcription factor unleashes blood vessel growth

Blood vessels play an important role throughout life. Their growth determines whether organs are supplied with nutrients in a timely manner during embryonic development. In adulthood, the development of new blood vessels is instrumental in repair and regeneration processes. When blood vessel growth is disturbed, it can be an important factor in the progression of cancer, diabetes and eye diseases. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim have now discovered that the growth of the innermost cell layer in blood vessels can be controlled via its metabolism. The results could serve as a basis for new treatments of diseases in which blood vessel growth plays a role.

Researchers test new pathogen detection technology

Patients who are undergoing treatment for diseases such as cancer often face the added challenge of a compromised immune system, which can be a toll both of their condition and the drugs used to treat it, leaving them vulnerable to various opportunistic infections. Many of these infections are not only life-threatening, but caused by rare organisms that are extremely difficult to isolate and identify. However, the sooner an infection is pinned down, the faster and more effectively it can be treated. After developing a novel investigational technology called PathoChip that can rapidly identify elusive microorganisms, a team of Penn Medicine researchers recently succeeded for the first time in identifying a pathogen in a patient sample, demonstrating the proof of principle that this technology can be used to identify pathogens in human disease.

Five ingredients that can help with weight management

Weight loss is often one of consumers' top resolutions for the New Year. While the basic premise of losing weight is to consume less calories than calories burned, weight management has evolved over the years and includes a focus on burning fat, building lean muscle, boosting metabolism and suppressing appetite. In the January issue of Food Technology magazine published by the Institute of Food Technologists (IFT), contributing editor Linda Milo Ohr writes about six ingredients that can play a role in weight management.

How reliable is resting state fMRI?

Arguably, no advance has revolutionized neuroscience as much as the invention of functional magnetic resonance imaging (fMRI). Since its appearance in the early 1990's, its popularity has surged; a PubMed search returns nearly 30,000 publications with the term "fMRI" since its first mention in 1993, including 4,404 last year alone. Still today, fMRI stands as one of the best available methods to noninvasively image activity in the living brain with exceptional spatiotemporal resolution. But the quality of any research tool depends foremost on its ability to produce results in a predictable and reasonable way. Despite its widespread use, and general acceptance its efficacy and power, neuroscientists have had to interpret fMRI results with a large dose of partially-blind faith, given our incomplete grasp of its physiological origins and reliability. In a monumental step towards validation of fMRI, in their new PLOS One study Ann C! hoe and colleagues evaluated the reproducibility of resting-state fMRI in weekly scans of the same individual over the course of 3.5 years.

An international team of researchers has uncovered new information about the Black Death in Europe and its descendants, suggesting it persisted on the continent over four centuries, re-emerging to kill hundreds of thousands in Europe in separate, devastating waves.

How munching Moa affected plant evolution

For his PhD in Ecology and Biodiversity, Patrick Kavanagh compared plant species on offshore islands to their close relatives on the mainland to assess differences in size and growth patterns.

Seagrass planting strategy needed to remove fast food option

Efforts to restore Shark Bay's seagrass meadows by transplanting Posidonia australis at the edge of existing meadows are being hampered because resident fish are using the new seagrass as fast food.

South-west bushfire turns up new flora

Biodiversity has flourished amid the devastation left by a bushfire that tore through a section of the south-west last year, with an Albany botanist discovering a plant species in the region.

No sex required: Team discovers gene trigger for asexual reproduction

When a sperm and an egg cell merge a new life begins. This is the case in humans and in animals, but in principle also in plants. A German-Israeli team led by the biologists Professor Ralf Reski from Freiburg and Professor Nir Ohad from Tel-Aviv has discovered a gene trigger in the moss Physcomitrella patens which leads to offspring without fertilization. The researchers assume that this mechanism is conserved in evolution and holds the key to answer fundamental questions in biology. The study is published in the journal Nature Plants.

Argentina snake invasion forces beach closures

An invasion of poisonous snakes washed downriver in recent floods forced authorities to close beaches to summer holidaymakers in northern Argentina, officials said Monday.

Rampaging elephants force Myanmar villagers to tree-top refuge

Pushed from their forest home by encroaching farm land, wild elephants are driving fearful villagers in a Myanmar township to seek refuge in tree houses while the animals storm their rice paddies looking for food.
