Self-replicating nanostructures made from DNA

(Phys.org)—Is it possible to engineer self-replicating nanomaterials? It could be if we borrow nature's building blocks. DNA is a self-replicating molecule where its component parts, nucleotides, have specific chemical interactions that allow for the design of self-assembled structures. In biological systems, DNA replicates with the aid of proteins. However, Junghoon Kim, Junwye Lee, Shogo Hamada, Satoshi Murata, and Sung Ha Park of Sungkyunkwan University and Tohoku University have designed a controllable self-replicating system that does not require proteins. Their work appears in Nature Nanotechnology.

Spiraling laser pulses could change the nature of graphene

A new study predicts that researchers could use spiraling pulses of laser light to change the nature of graphene, turning it from a metal into an insulator and giving it other peculiar properties that might be used to encode information.

Could computers reach light speed?

Light waves trapped on a metal's surface travel nearly as fast as light through the air, and new research at Pacific Northwest National Laboratory shows these waves, called surface plasmons, travel far enough to possibly be useful for ultra-fast electronic circuit interconnects. The PNNL team captured, on video, surface plasmons moving at least 250 microns across the surface.

Physicists precisely measure interaction between atoms and carbon surfaces

Physicists at the University of Washington have conducted the most precise and controlled measurements yet of the interaction between the atoms and molecules that comprise air and the type of carbon surface used in battery electrodes and air filters—key information for improving those technologies.

Researchers prove magnetism can control heat, sound

Phonons—the elemental particles that transmit both heat and sound—have magnetic properties, according to a landmark study supported by Ohio Supercomputer Center (OSC) services and recently published by a researcher group from The Ohio State University.

What's fair?: New theory on income inequality

The increasing inequality in income and wealth in recent years, together with excessive pay packages of CEOs in the U.S. and abroad, is of growing concern, especially to policy makers. Income inequality was identified as the #1 Top 10 Challenging Trends at the 2015 World Economic Forum annual meeting in Davos last January. Columbia Engineering Professor Venkat Venkatasubramanian has led a study that examines income inequality through a new approach: he proposes that the fairest inequality of income is a lognormal distribution (a method of characterizing data patterns in probability and statistics) under ideal conditions, and that an ideal free market can "discover" this in practice.

How researchers listen for gravitational waves

A century ago, Albert Einstein postulated the existence of gravitational waves in his General Theory of Relativity. But until now, these distortions of space-time have remained stubbornly hidden from direct observation. At the Max Planck Institute for Gravitational Physics in Hanover, researchers are on the trail of this phenomenon with the GEO600 detector. At the heart of the installation is a laser.

Donuts, math, and superdense teleportation of quantum information

Putting a hole in the center of the donut—a mid-nineteenth-century invention—allows the deep-fried pastry to cook evenly, inside and out. As it turns out, the hole in the center of the donut also holds answers for a type of more efficient and reliable quantum information teleportation, a critical goal for quantum information science.

Endless oscillations: A theoretical study on quantum systems

A quantum system never relaxes. An isolated system (like a cloud of cold atoms trapped in optical grids) will endlessly oscillate between its different configurations without ever finding peace. In practice, these types of systems are unable to dissipate energy in any form. This is the exact opposite of what happens in classical physics, where the tendency to reach a state of equilibrium is such a fundamental drive that is has been made a fundamental law of physics, i.e., the second law of thermodynamics, which introduces the concept of entropy.

An efficient approach to concentrate arbitrary N-particle W state

Entanglement is an important quantum resource in both quantum communication and computation. The applications of entanglement information processing such as quantum teleportation, quantum key distribution (QKD), quantum dense coding, quantum secret sharing (QSS), and quantum secure direct communication (QSDC) all resort the entanglement to set up the quantum channel between long distant locations. The multi-particle W entangled state cannot be converted to the Greenberger-Horne-Zeilinger (GHZ) state directly with local operation and classical communication (LOCC). The multi-particle W entangled state also plays an important role in quantum information processing, such as teleportation, superdense coding, and so on.

NIST seeks calibration methodologies for determining the accuracy of micro-flows

Many medical treatments both new and old involve extremely small doses of powerful drugs in liquid form – from scorpion venom for cancer research to opioid analgesics for pain control. Often, these substances are administered on the scale of a few tens of nanoliters (nL, billionths of a liter) at a time.

Global climate on verge of multi-decadal change

A new study, by scientists from the University of Southampton and National Oceanography Centre (NOC), implies that the global climate is on the verge of broad-scale change that could last for a number of decades.

Volcanic ash proves inefficient cloud ice maker

When tons of ash spewed into the atmosphere from a 2010 Icelandic volcano it caused havoc for vacationers across Europe. But did it also dramatically change clouds? Researchers at Pacific Northwest National Laboratory found that volcanic ash is not as efficient as common dust in birthing clouds' ice particles. Using a novel laboratory testing chamber they formed cloud ice, a process called ice nucleation, around particles of dust and volcanic ash. Their results revealed the importance of optimal particle structure to efficiently attract super cold water vapor to nucleate ice.

Large igneous provinces associated with mid-ocean ridges

Lip reading normally involves deciphering speech patterns, movements, gestures and expressions just by watching a person speak. Planet Earth has LIPS, too - they are an acronym for large igneous provinces, huge accumulations of igneous rocks that form when hot magma extrudes from inside the Earth and flows onto the surface of the seafloor under several kilometres of water.

Technologies will tackle irrigation inefficiencies in agriculture's drier future

Water is a finite but crucial resource. In most river basins around the world, water is diverted for industrial, municipal and domestic consumption. It's also a critical component of wetlands and other natural ecosystems that are of tremendous value to society. Worldwide, the bulk of water use is tied to agriculture – it accounts for approximately 66% of water diverted from natural sources for human use and 85% of water consumption. In the arid western United States, it's not uncommon for irrigation to represent 75%-90% of all diversions.

The Albian Gap, salt rock, and a heated debate

Salt rock behaves as a fluid and can play a pivotal role in the large-scale, long-term collapse of the world's continental margins. However, the precise way in which this occurs is laced in controversy; nowhere is this controversy more apparent than along the Brazilian continental margin, where the origin of a feature called "the Albian Gap" has generated much heated debate over several decades.

New planning toolset gives farmers more options for improving water quality

With agriculture increasingly on the hook to improve water quality, curb erosion, and meet other environmental goals, it only makes sense to target soil and water conservation practices to the places on the landscape where they'll do the most good. Exactly how to achieve this is the catch, but a promising new solution is now at the ready, thanks to research led by the USDA-Agricultural Research Service (USDA-ARS) and Environmental Defense Fund.

The kinematics of merging galaxies

The unprecedented sensitivity of space telescopes has powered a revolution over the past decade in our understanding of galaxies in the young universe during its first billion years of existence. These primitive objects are so remote that their light has been traveling towards us for more than ninety percent of the age of the universe, but they could be detected by space observatories because they are intrinsically bright in the infrared. Their luminosity is almost surely the result of huge numbers of newly formed stars whose light warms the dust that then radiates at infrared wavelengths.

Large Hubble survey confirms link between mergers and supermassive black holes with relativistic jets

In the most extensive survey of its kind ever conducted, a team of scientists have found an unambiguous link between the presence of supermassive black holes that power high-speed, radio-signal-emitting jets and the merger history of their host galaxies. Almost all of the galaxies hosting these jets were found to be merging with another galaxy, or to have done so recently. The results lend significant weight to the case for jets being the result of merging black holes and will be presented in the Astrophysical Journal.

Dawn spirals closer to Ceres, returns a new view

Shining message about the end of the Dark Ages

An international team, including researchers from the Centre for Astronomy of Heidelberg University (ZAH), has discovered three "cosmic Methusalems" from the earliest years of the universe. These unusual stars are about 13 billion years old and experts assign them to the first generations of stars after the "dark ages". The chemical qualities of these extremely rare stellar bodies enable new insights into the events that must have led to the origins of the stars. The first stars have been assumed to be high-mass and to shine especially brightly. However, the latest observations point to hitherto unknown phenomena in the young universe, allowing for the emergence of much smaller stars. This conclusion is suggested by analyses in part conducted at the State Observatory Königstuhl and at the Institute of Theoretical Astrophysics, both of which belong to the ZAH.

Pro­fessor of materials/​physics chem­istry discusses Tesla's Powerwall for home energy storage

Last month Tesla CEO Elon Musk unveiled a grand plan for home energy storage, and preorders for the system have already sold out until mid-2016. The Powerwall home battery unit comes in two options: a 7 kWh version designed for daily use at $3,000 and a 10 kWh version designed as a backup supply for $3,500, plus installation. It would charge using electricity generated from solar panels—or when energy rates are low—and would also serve as an alternative to using the utility grid and as a backup in case of a power outage. Powerwall's lithium-ion battery is geared toward homeowners and is based on the technology used in Tesla vehicles.

New work from a team including Carnegie's Devaki Bhaya and Michelle Davison used massive DNA sequencing of bacterial populations that grow in the hot springs in Yellowstone National Park to determine their genetic diversity and explore the underlying evolutionary dynamics. They found an unexpectedly high degree of sharing and exchange of genetic material between the tiny, green, photosynthetic cyanobacteria Synechococcus, which are abundant in these scalding, inhospitable environments.

Understanding how cells follow electric fields

Many living things can respond to electric fields, either moving or using them to detect prey or enemies. Weak electric fields may be important growth and development, and in wound healing: it's known that one of the signals that guides cells into a wound to repair it is a disturbance in the normal electric field between tissues. This ability to move in response to an electric field is called galvanotaxis or electrotaxis.

Study tackles evolution mystery of animal, plant warning cues for survival

Not every encounter between predator and prey results in death. A new study co-authored by a University of Tennessee, Knoxville, professor suggests that prey emit warning cues that can ultimately lead to both their survival and that of their predators.

Scientists see a natural place for 'rewilded' plants in organic farming

One of the key elements of organic agriculture, as defined by the International Federation of Organic Agriculture Movements (IFOAM), is that it rejects unpredictable technologies, such as genetic engineering. But what if adding a gene from undomesticated plants to bring back a natural trait isn't unpredictable, argue Danish scientists, ethicists, and legal experts in a review published May 28 in Trends in Plant Science. They present a case for using precise genetic engineering technologies to "rewild" crops in a way that would make organic farming more efficient, and thus more profitable.

Researchers uncover the oldest tea in Britain

KeyGenes can predict future identity of human fetal stem cells

A snapshot of gene activity is now all that's necessary to determine what organ or tissue type that a cluster of fetal stem cells will ultimately become. An algorithm developed by a team of Dutch scientists makes it possible to match what's happening inside of an immature stem cell to known human fetal cell gene expression, thus identifying what the stem cell has the potential to be. The platform, dubbed KeyGenes and presented May 28 in Stem Cell Reports, could also prove useful for testing the quality of stem cell transplants made up of undifferentiated cells.

Scientists use unmanned aerial vehicle to study gray whales from above

One recent spring day, John Durban, a NOAA Fisheries marine mammal biologist, stood on the California coast and launched an unmanned aerial vehicle into the air. The hexacopter—so called because it has six helicopter-type rotors—zipped over the ocean and hovered above a gray whale mother and her calf. The pair was migrating north from their calving grounds off Baja California, Mexico, to their summer feeding grounds in the Arctic.

First step towards global attack on potato blight

European researchers and companies concerned with the potato disease phytophthora will work more closely with parties in other parts of the world. The first move was made during the biennial meeting of the European network EuroBlight, held in Romania earlier this month. Colleagues from North-America, South-America and Asia were also invited. "They are very interested in our approach; the way we analyse the genetic variation in the field, for example", says Huub Schepers, phytophthora specialist at Wageningen UR and one of the driving forces behind EuroBlight. "Conversely, we can learn a lot from them. The more we know about this pathogen, the more we can do to devise a comprehensive strategy."

Thirteen corporations control up to 40 per cent of world's most valuable fisheries

Just thirteen corporations control 19-40% of the largest and most valuable stocks and 11-16 % of the global marine catch, according to new research. These "keystone" corporations of the global seafood industry critically shape the future of marine ecosystems, but have yet to assume this responsibility at the global scale.

Public raises alarm about ineffectiveness of some Montagu's harrier conservation measures

A citizen science programme reveals the protection measures for the Montagu's harrier in the cereal crop season in France to be ineffective if nests are not protected to decrease predation after harvesting. A study has been published as a result of this voluntary fieldwork, with the participation of the Hunting Resources Research Institute, which proposes fencing off the nests as a way of mitigating the damage and optimising conservation efforts in different areas.

Progression-free survival (PFS) in patients previously treated with crizotinib was 13.4 months.

Importance of clinically actionable results in genetic panel testing for cancer

While advances in technology have made multigene testing, or "panel testing," for genetic mutations that increase the risk of breast or other cancers an option, authors of a review published today in the New England Journal of Medicine say larger studies are needed in order to provide reliable risk estimates for counseling these patients. The international consortium of authors, including researchers at the Basser Center for BRCA at the University of Pennsylvania's Abramson Cancer Center, acknowledges that panel testing can make a useful contribution to predicting a woman's risk of breast cancer, but says clinicians need to be aware of the limitations. The note of caution comes following news of low-cost genetic testing solutions for breast and ovarian cancer mutations.

Starting antiretroviral treatment early improves outcomes for HIV-infected individuals

A major international randomized clinical trial has found that HIV-infected individuals have a considerably lower risk of developing AIDS or other serious illnesses if they start taking antiretroviral drugs sooner, when their CD4+ T-cell count—a key measure of immune system health—is higher, instead of waiting until the CD4+ cell count drops to lower levels. Together with data from previous studies showing that antiretroviral treatment reduced the risk of HIV transmission to uninfected sexual partners, these findings support offering treatment to everyone with HIV.

Molecules involved in Alzheimer's have a role in weakening of connections between neurons

Alzheimer's disease is the most common form of dementia, affecting over 44 million people worldwide. Inside the brain, Alzheimer's disease is characterized by loss of neurons, and presence of abnormal tangles and plaques in the brain. Dr. Graham Collingridge, recently recruited from Bristol (U.K.) to the University of Toronto, has found that molecules that are strongly associated with Alzheimer's disease are important players in a process called long-term depression (LTD). LTD is a process through which the strength of synapses, the connections between neurons, is selectively reduced. Dr. Collingridge's recent research suggests improperly regulated LTD could cause the degeneration of the connections between neurons that is a core feature of Alzheimer's and other neurodegenerative diseases.

Why male suicides outnumber female

Finally, Drummond had everything he'd ever dreamed of. He'd come a long way since he was a little boy, upset at his failure to get into the grammar school. That had been a great disappointment to his mother, and to his father, who was an engineer at a pharmaceutical company. His dad had never showed much interest in him as a child. He didn't play with him and when he was naughty, he'd put him over the back of a chair and wallop him. That's just the way men were in those days. Your father was feared and respected. Dads were dads.

Nearly one in seven Hispanic/Latino adults has some hearing loss

In the largest study to date of hearing loss among Hispanic/Latino adults in the United States, researchers have found that nearly 1 in 7 has hearing loss, a number similar to the general population prevalence. The analysis also looked at the differences between subgroups and found that Hispanics of Puerto Rican descent have the highest rate of hearing loss, while Mexican-Americans have the lowest. The study identified several potential risk factors for hearing loss, including age, gender, education level, income, noise exposure, and diabetes. The study, which was supported by the National Institutes of Health (NIH), was published online May 28 by JAMA Otolaryngology—Head and Neck Surgery.

Controlling typhoid bacterium key to prevent gallbladder cancer in India and Pakistan

Controlling bacterial infections responsible for typhoid fever could dramatically reduce the risk of gallbladder cancer in India and Pakistan, according to a study published by Cell Press May 28th in Cell Host & Microbe. The findings establish for the first time the causal link between bacterial infection and gallbladder cancer, explaining why this type of cancer is rare in the West but common in India and Pakistan, where typhoid fever is endemic. Public policy changes inspired by this research could have an immediate impact on preventing a type of cancer that currently has a very poor prognosis.

A new tool to study an important anti-cancer and immunosuppressive target

The chemical rapamycin is used clinically as an immunosuppressant and as an anti-cancer agent that works by inactivating a protein named TOR (Target Of Rapamycin). This protein is essential for the growth of normal cells, but is hyperactive in tumor cells. To be able to carry out its various growth-related tasks, TOR needs to assemble into one of two larger protein complexes named TORC1 and TORC2. Curiously, whereas TORC1 is inhibited by rapamycin, TORC2 is unaffected by this drug. The team of Robbie Loewith, professor in biology at the University of Geneva (UNIGE), Switzerland, has just lifted the veil on this mystery.

New findings shed light on complexities of emerging zoonotic malaria
