Researchers characterize mysterious ultraluminous X-ray sources

(Phys.org)—Many black holes are believed to have surrounding accretion disks of matter trapped by gravity and spiraling toward the event horizon. Supercritical accretion disks (SCADs) are those with mass accretion rates exceeding the Eddington limit—this describes the maximum possible luminosity of an energetic body when the outward force of radiation is in equilibrium with gravitation. Masses that exceed the Eddington luminosity to produce SCADs emit extremely intense stellar winds from their outer layers.

Rosetta's comet remains active after nightfall and emits dust jets into space

When night falls on Rosetta's comet 67P/Churyumov-Gerasimenko, the bizarrely shaped body remains active. This can be seen in new images of the Ma'at region located on the comet's "head" captured by OSIRIS, the scientific imaging system on board the Rosetta spacecraft. They were taken approximately half an hour after the Sun had set over the region and show clearly distinguishable jets of dust escaping into space. Researchers from the OSIRIS team believe that the increasing heating-up of the comet is responsible for the newly observed phenomenon.

'Alzheimer's protein' plays role in maintaining eye health and muscle strength

Amyloid precursor protein (APP), a key protein implicated in the development Alzheimer's disease, may play an important role in eye and muscle health. In a new report published in the June 2015 issue of The FASEB Journal, scientists have discovered that when proteins that bind to the APP, called FE65 and FE65L1, are deleted, they cause cataracts and muscle weakness in mice. Additionally, this study demonstrates that the expression of laminin, a protein pivotal for the interaction between lens epithelial cells and the lens capsule, is severely altered in mice lenses missing both FE65 and FE65L1 genes. If confirmed in human studies, the FE65 and FE65L1 proteins may become a therapeutic target for cataracts, muscular dystrophy and Alzheimer's disease.

(Phys.org)—A team of researchers from a wide variety of institutions in France has concluded that it appears likely that approximately seven percent of all modern invertebrates have gone extinct. In their paper published in Proceedings of the National Academy of Sciences, the team outlines the research they conducted on land snail extinctions and how they extrapolated what they found to apply to non-marine invertebrates extinctions worldwide in the modern age.

Largest-ever scientific camera trapping survey reveals 'secret lives of the Serengeti'

The use of camera traps—remote automatic cameras triggered by heat or motion—has revolutionized wildlife ecology and conservation research. But the large number of images generated through the traps creates the problem of categorizing and analyzing all the images.

Discovery in plant growth mechanisms opens new research path

New findings reported this week by plant molecular biologists at the University of Massachusetts Amherst are deepening scientists' views of a cell surface regulator, FERONIA receptor kinase from the model plant Arabidopsis, once thought to be involved only in reproduction but in fact required throughout plant growth, development and in surviving environmental challenges.

Many experiments for the price of one: A breakthrough in the study of gene regulation

Inside every cell that makes up a diminutive fruit fly is a vast, dynamic network of information—the genome whose 15,000 genes allow that cell to function. In a study recently published as a breakthrough article in Nucleic Acids Research, computer scientists and molecular biologists demonstrated the utility of a novel approach to deciphering how networks of genes are regulated.

Tree root research confirms that different morphologies produce similar results

Despite markedly different root morphologies and resulting disparities in nutrient-uptake processes, forest trees of different lineages show comparable efficiency in acquiring soil nutrients, according to researchers in Penn State's College of Agricultural Sciences.

Once-abundant bird being eaten to worldwide extinction by China

A bird that was once one of the most abundant in Europe and Asia is being hunted to near extinction because of Chinese eating habits, according to a study published on Tuesday.

Insect's wings key to azalea pollination

A researcher from North Carolina State University has found that in the case of the flame azalea (Rhododendron calendulaceum), all pollinators are not created equal. In fact, due to the flower's unique reproductive structure, butterflies – and specifically, their wings – are the key to pollination.

Free app helps distinguish diseased from healthy plant tissues

A new app lets users practice eMedicine on plants.

Small changes have large benefits for crop breeding

Researchers from The University of Western Australia have developed a new method for breeding crops that will improve the potential for long-term, sustainable genetic improvement.

Before we build Jurassic World, we need to study recent extinctions

It's hard to have a conversation about bringing extinct creatures back to life without a tip-of-the-hat to Jurassic Park, or the latest instalment, Jurassic World, due out Thursday. Massive people-eaters escaping their bonds and ravaging humanity may make good cinema but the arguments both for and against de-extinction are more subtle and wide ranging.

Emerging weeds show resilience to herbicide treatments

With herbicide resistance in common weeds already impacting significantly on the WA grain industry's profitability, evidence has now been found of resistance issues in lesser-known and emerging weeds.

Crop-rotation resistant rootworms have a lot going on in their guts

After decades of effort, scientists are finally figuring out how insects develop resistance to environmentally friendly farming practices - such as crop rotation - that are designed to kill them. The researchers say their insights will help develop more sustainable agricultural practices.

New species of leafminer on grapevine in Western Cape came from wild grapes

Since 2011 an unknown leafmining moth was observed in table grape orchards and often in large numbers in the Paarl region of the Western Cape (South Africa).

Longest ever tiger shark tracking reveals remarkable, bird-like migrations

Tiger sharks are among the largest and most recognizable sharks on the planet, yet many of their habits remain mysterious because they are long-distance travelers that are hard to track. But a new study, reported in the June 9 issue of the journal Scientific Reports, has yielded the first ever continuous, two or more-year satellite tagging tracks for the animals. This study reveals remarkable, and previously unknown, migration patterns more similar to birds, turtles and some marine mammals than other fishes.

Collaboration of citrus greening researchers begins 5-year plan to save citrus

A diverse group of researchers has teamed up to develop a therapeutic treatment for citrus greening disease, a bacterial infection that threatens the future of the U.S. citrus industry.

Discovering a new force driving cell contraction during development and organogenesis

CRG scientists describe a new mechanism shaping cells and generating cell contractile forces during development and organogenesis. The new mechanism, which has been published today in the journal Developmental Cell, includes strategies shared with programmed cell death but which have not previously been directly associated with force generation. Studying developmental processes contributes to a better understanding of organ development and maintenance. Also, the specific process of dorsal closure described in this work is one of the most studied ones because of its similarity with wound healing.

South African medics make big effort to save Hope the rhino

The horns and a large portion of the rhino's face were severed by poachers, a horrific injury that had some observers wincing at the sight of exposed flesh and bone. One South African veterinarian treating the mutilated survivor was so distressed at the rhino's suffering that he stepped away briefly, his eyes glassy with tears.
