	Blood biopsy: Releasing cancer cells for better analysis A new device developed at the University of Michigan could provide a non-invasive way to monitor the progress of an advanced cancer treatment.
	Nanocrack coating allows membranes to work in high temperature, low humidity environments (Phys.org)—A team of researchers with members from institutions in South Korea and Australia has developed a coating for membranes used in fuel cells and many other applications that allows it to continue to perform at a high level even as temperatures rise and humidity drops to levels that normally cause performance to suffer. In their paper published in the journal Nature, the team describes their coating, how it works and the different materials that can be improved through its use. Jovan Kamcev and Benny Freeman with the University of Texas at Austin have published a News & Views article in the same journal issue describing the work done by the team and the many ways that the membrane coating has been successfully tested.
	Exploring phosphorene, a promising new material Two-dimensional phosphane, a material known as phosphorene, has potential application as a material for semiconducting transistors in ever faster and more powerful computers. But there's a hitch. Many of the useful properties of this material, like its ability to conduct electrons, are anisotropic, meaning they vary depending on the orientation of the crystal. Now, a team including researchers at Rensselaer Polytechnic Institute (RPI) has developed a new method to quickly and accurately determine that orientation using the interactions between light and electrons within phosphorene and other atoms-thick crystals of black phosphorus.

Physics news

	'Game-changer' for photonics applications: Researchers demonstrate record optical nonlinearity Work by an internationally renowned University of Rochester professor may offer an alternative to the way in which researchers have approached some photonics applications.
	Fiber optic biosensor-integrated microfluidic chip to detect glucose levels Insulin deficiency and hyperglycemia are two well-known culprits behind diabetes, both of which are reflected in blood glucose concentrations. Now, researchers are working to create ultrasensitive lab-on-a-chip devices to quickly measure glucose concentrations with the goal of developing device for early diagnosis and prevent of diabetes
	Closing the ring How bacterial cells divide in two is not fully understood. LMU physicists now show that, at high concentrations, a crucial protein can assemble into ring-shaped filaments that constrict the cell, giving rise to two daughter cells.

Earth news

	Geochemical detectives use lab mimicry to look back in time New work from a research team led by Carnegie's Anat Shahar contains some unexpected findings about iron chemistry under high-pressure conditions, such as those likely found in the Earth's core, where iron predominates and creates our planet's life-shielding magnetic field. Their results, published in Science, could shed light on Earth's early days when the core was formed through a process called differentiation—when the denser materials, like iron, sunk inward toward the center, creating the layered composition the planet has today.
	Scientists reveal origin of Earth's oldest crystals New research suggests that the very oldest pieces of rock on Earth—zircon crystals—are likely to have formed in the craters left by violent asteroid impacts that peppered our nascent planet, rather than via plate tectonics as was previously believed.
	Carbon stored in Pacific Northwest forests reflects timber harvest history The amount of carbon stored in tree trunks, branches, leaves and other biomass—what scientists call "aboveground live carbon"—is determined more by timber harvesting than by any other environmental factor in the forests of the Pacific Northwest, according to a report published by researchers at Oregon State University.
	Fracking would pose no danger to water supplies, new research suggests Potential future fracking activity in the UK is unlikely to pose a pollution danger to overlying aquifers, new research from a leading academic suggests.
	Insect outbreaks reduce wildfire severity Forest scientists have found an unexpected 'silver lining' to the insect outbreaks that have ravaged millions of trees across western North America.
	Water storage made prehistoric settlement expansion possible in Amazonia The pre-Columbian settlements in Amazonia were not limited to the vicinities of rivers and lakes. One example of this can be found in the Santarém region in Brazilian Amazonia, where most archaeological sites are situated in an upland area and are the result of an expansion of settlements in the last few centuries before the arrival of Europeans. This is concluded by a research team consisting of archaeologists from the University of Gothenburg and Brazilian colleagues.
	Amazon rainforest responds quickly to extreme climate events A new study examining carbon exchange in the Amazon rainforest following extremely hot and dry spells reveals tropical ecosystems might be more sensitive to climate change than previously thought.
	Ice loss accelerating in Greenland's coastal glaciers, study finds Surface meltwater draining through and underneath Greenland's tidewater glaciers is accelerating their loss of ice mass, according to a Dartmouth study that sheds light on the relationship between meltwater and subglacial discharge.
Not just climate change: Study finds human activity is a major factor driving wildfires A new study examining wildfires in California found that human activity explains as much about their frequency and location as climate influences. The researchers systematically looked at human behaviors and climate change together, which is unique and rarely attempted on an area of land this large.
	Workers feeling the heat as climate change slashes productivity Climate change is exposing millions of workers to excessive heat, risking their health and income and threatening to erase more than $2.0 trillion in annual productivity by 2030, a UN report warned Thursday.
	A milestone in the battle against arsenic- and fluoride-contaminated drinking water Over 300 million people worldwide use groundwater contaminated with arsenic or fluoride as a source of drinking water. The Swiss Federal Institute of Aquatic Science and Technology (Eawag) has developed a method whereby the risk of contamination in a given area can be estimated using geological, topographical and other environmental data without having to test samples from every single groundwater resource. The research group's knowledge is now being made available free of charge on an interactive Groundwater Assessment Platform (GAP). gapmaps.org enables authorities, NGOs and other professionals to upload their own data and generate hazard maps for their areas of interest.

The scientists can concentrate the purified molecules into a beam and control its size, shape, and position to prepare highly tailored films and structures.

Biology news

	Study shows reptiles share REM and slow-wave sleep patterns with mammals, birds Behavioural sleep is ubiquitous among animals, from insects to man. In humans, sleep is also characterized by brain activity: periods of slow-wave activity are each followed by short phases of Rapid-Eye-Movement sleep (REM sleep). These electrical features of brain sleep, whose functions are not well understood, have so far been described only in mammals and birds, but not in reptiles, amphibians or fish. Yet, birds are reptiles—they are the feathered descendants of the now extinct dinosaurs. How then did brain sleep evolve? Gilles Laurent and members of his laboratory at the Max Planck Institute for Brain Research in Frankfurt, Germany, describe for the first time REM and slow-wave sleep in a reptile, the Australian dragon Pogona vitticeps. This suggests that brain sleep dates back at least to the evolution of the amniotes, that is, to the beginning of the colonization of terrestrial landmass by vertebrate animals.
	Hear no evil: Farmed fish found to be hard of hearing New research published today in the journal Scientific Reports has revealed for the first time that half of the world's farmed fish have hearing loss due to a deformity of the earbone.

Fungal spores could 'hijack' human immune cells to spread infection Scientists have announced a major breakthrough in their understanding of how the fungus Aspergillus terreus - the cause of serious illness in humans - can move around the body, rather than remaining in the lungs as with similar fungal infections.
	Study identifies a key to bone formation and vertebrate evolution Researchers in a USC-led study said they have identified a key action of a watershed gene critical to bone formation and the evolution of vertebrates.
	Stem cells know how to open up and unwind Research led by the Babraham Institute with collaborators in the UK, Canada and Japan has revealed a new understanding of how an open genome structure supports the long-term and unrestricted developmental potential in embryonic stem cells. This insight provides new avenues for improving the quality and stability of embryonic stem cells - an essential requirement to fulfil their promise in regenerative medicine.
	RNA splicing mutations play major role in genetic variation and disease RNA splicing is a major underlying factor that links mutations to complex traits and diseases, according to an exhaustive analysis of gene expression in whole genome and cell line data. Reporting in Science on April 29, 2016 researchers from the University of Chicago and Stanford University studied how thousands of mutations affect gene regulation in traits such as height, and diseases such as multiple sclerosis. The findings highlight the need for a better understanding of the role of RNA splicing on variation in complex traits and disease, and enable more accurate functional interpretations of genome-wide association study results.
	New data analysis technique distinguishes active from passive fluctuations inside cells Inside every living cell, internal structures are continuously moving about. Under a microscope, organelles such as the nucleus, mitochondria, transport vesicles, or even external flagella wobble and twitch. This may happen spontaneously as these tiny structures are passively jostled inside a cell. But that's not necessarily all there is to it. Often a cell invests extra energy into these motions to enhance cell functions in ways we don't yet understand.
	A long-noncoding RNA regulates repair of DNA breaks in triple-negative breast cancer cells The discovery of long non-coding RNA (lncRNA) has dramatically changed the understanding of the biology of diseases such as cancer.

	Researchers find genes that influence dizygotic twinning and fertility Twinning has fascinated human beings over the centuries. Twins are relatively common and occur more than 1 time per 100 maternities. Roughly two-thirds of all twin pairs are dizygotic or non-identical and are genetically as alike as other siblings. It has been firmly established that dizygotic twinning has a maternal genetic component, but no one so far has succeeded in identifying the genes for spontaneous DZ twinning after decades of investigations.
	Co-expression of alternative gene products helps neurons take shape The human genome contains some 20,000-25,000 protein-coding genes, which is surprisingly similar to the number of genes in worms and flies. Where does complexity of our organism and behaviour come from? In many genes, coding regions called "exons" are separated by intervening "introns". Mammals may substantially increase their molecular complexity by removing introns and joining exons in a combinatorial manner. This process known as "alternative splicing" and allowing a single gene to generate multiple protein variants is especially prevalent in the mammalian brain. However, to what extent alternative splicing increases the number of functionally important proteins in individual neurons remains an open question.
Gestational exposure to type of antidepressants associated with adolescent depression A study to be published in the May 2016 issue of the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP) reports that use of certain antidepressants during pregnancy can result in offspring depression by early adolescence.
From retina to cortex: Unexpected division of labor Neurons in our brain do a remarkable job of translating sensory information into reliable representations of our world that are critical to effectively guide our behavior. The parts of the brain that are responsible for vision have long been center stage for scientists' efforts to understand the rules that neural circuits use to encode sensory information. Years of research have led to a fairly detailed picture of the initial steps of this visual process, carried out in the retina, and how information from this stage is transmitted to the visual part of the cerebral cortex, a thin sheet of neurons that forms the outer surface of the brain. We have also learned much about the way that neurons represent visual information in visual cortex, as well as how different this representation is from the information initially supplied by the retina. Scientists are now working to understand the set of rules—the neural blueprint— that exp! lains how these representations of visual information in the visual cortex are constructed from the information provided by the retina. Using the latest functional imaging techniques, scientists at MPFI have recently discovered a surprisingly simple rule that explains how neural circuits combine information supplied by different types of cells in the retina to build a coherent, information-rich representation of our visual world.

	BPA determined to have adverse effects on couples seeking in vitro fertilization Bisphenol A (BPA) is an industrial chemical that is used in a variety of consumer products, such as water bottles, metal food and beverage containers, and thermal paper cash register receipts. Long considered to have health effects on animals and humans, exposure to BPA may lead to reduced quality of embryos during reproduction. Fred vom Saal, a University of Missouri endocrinologist and researcher, has studied BPA and its effects on the reproductive system for more than 20 years. Now, a new study has corroborated his work showing that BPA causes a linear increase in the death rate of embryos and could be the cause for decreases in the frequency of implantation, pregnancy and live birth rates in couples seeking in vitro fertilization (IVF). Vom Saal, who wrote a review of the study, says that this is more proof that BPA usage should cease.
