Physicists energized about restart of Large Hadron Collider

When Kevin McDermott and Susan Dittmer talk about what they might discover when their particle detector goes back online in Switzerland, it's a little like talking to a 5-year-old on Christmas Eve.

Researchers observe new charge transport phenomenon

Researchers of Aalto University in Finland and the German University of Marburg have collaborated in the study of the movement of charges over interfaces of semiconductor materials. The group noticed a new kind of transport phenomenon for charges. In the phenomenon, a pair formed by a negative electron and a positive charge moves onto an interface, after which its 'message' is passed on to the other side of the interface, where it is carried on by a similar pair. The new theoretical result opens up interesting prospects for carrying out logical operations in electronics.

Revisiting the mechanics of the action potential

The action potential is widely understood as an electrical phenomenon. However, a long experimental history has documented the existence of co-propagating mechanical signatures.

Earth news

California Tuolumne snowpack 40 percent of worst year

New NASA data find the snowpack in the Tuolumne River Basin in California's Sierra Nevada—a major source of water for millions of Californians—currently contains just 40 percent as much water as it did near this time at its highest level of 2014, one of the two driest years in California's recorded history. The data were acquired through a partnership with the California Department of Water Resources, the San Francisco Public Utilities Commission and the Turlock and Modesto irrigation districts.

Engineering undergraduates characterize sulfur emissions from Hawaiian volcano

Since 1983, the 180,000 residents of the Big Island of Hawaii have lived in the wake of the pollution caused by the active shield volcano Kilauea. The destructive nature of the volcanic smog ("vog") has imprinted a significant ecological footprint on the surrounding infrastructure, vegetation, and human health.

New data allows broad view of human influence on Pacific ecosystems

As man-made threats to coral reefs mount, and interest in conserving reef ecosystems grows, scientists have turned to studying extremely remote and uninhabited reefs in an effort to understand what coral reefs would be like in the absence of humans. A number of islands and atolls in the Pacific Ocean remain virtually untouched by human influence, situated hundreds of kilometers from the nearest human populations.

Astronomy & Space news

Model shows how gas giants could have survived and spun away from their star

(Phys.org)—A new model developed by a team of researchers with member affiliations in Argentina, France and Mexico, depicts a possible scenario to explain why gas giants do not migrate into the star they are orbiting during their early stages. In their paper published in the journal Nature, the researchers note that prior efforts to build a model that could explain gas giant growth and behavior did not take tidal effects into account and thus could not show why they survived. Martin Duncan of Queen's University offers a News & Views piece on the work done by the team in the same journal issue.

Chemistry news

Using DNA to assemble a protein lattice

(Phys.org)—Living systems have ready-made catalysts, known as enzymes, for many types of reactions. What if these enzymes could be snapped together like Lego pieces to make a lattice structure? An ideal procedure for accomplishing this would be versatile enough to work with any protein, regardless of its identity, and would maintain the protein's native functionality while in the lattice structure.

Scientists develop perfume which smells better the more you sweat

The first-ever perfume delivery system to ensure the more a person sweats, the better they will smell, has been developed by scientists at Queen's University Belfast.

Findings on how electrons are solvated in water widen the range of potential influences on chemical reactions

Chemistry can be quite confusing. In order for the desired substance to be produced in a reaction or for two substances to interact - or not - chemists have to take into account a number of factors. Researchers at the Fritz Haber Institute of the Max Planck Society in Berlin can now offer them additional access. They have measured how strongly electrons are bound when they are put into water – namely right at the start as soon as the negative charge carriers are released by, for instance, a potential reaction partner. Electrons are the actual players in chemical reactions, as they are moved between different atoms during this process. Whether that happens depends on their binding energy to the different components. And in reactions in aqueous solutions, the binding energy of an electron at the beginning of the solvation process is a key factor. Now that it is known, chemists can consider it when planning or preventing reactions.!

Researchers use silk to cultivate organ tissues in the lab

Few organs in the body are as complicated as the human brain, a tight spiderweb of neurons that shoots electrical signals across synapses to control all our thoughts and movements. When something goes wrong—as it does when a person suffers a traumatic brain injury—the effects can be devastating. But for decades, scientists have been stymied in trying to study the living brain in the laboratory.

Scientists synthesize molecules that absorb any color of sunlight, from the oranges through the near-infrared

In 2005, scientists studying tiny sac-like creatures called sea squirts found bacteria containing two types of chlorophyll (a and b) in cavities inside the squirts' tissues. These two pigments were soaking up most of the sunlight—the violets, indigos, blues, green, yellows and oranges.

'Open' stem cell chromosomes reveal new possibilities for diabetes

Stem cells hold great promise for treating a number of diseases, in part because they have the unique ability to differentiate, specializing into any one of the hundreds of cell types that comprise the human body. Harnessing this potential, though, is difficult. In some cases, it takes up to seven carefully orchestrated steps of adding certain growth factors at specific times to coax stem cells into the desired cell type. Even then, cells of the intestine, liver and pancreas are notoriously difficult to produce from stem cells. Writing in Cell Stem Cell April 2, researchers at University of California, San Diego School of Medicine have discovered why.

With geomagnetic compass hooked to the brain, blind rats act like they can see

By attaching a microstimulator and geomagnetic compass to the brains of blind rats, researchers reporting in the Cell Press journal Current Biology on April 2 found that the animals can spontaneously learn to use new information about their location to navigate through a maze nearly as well as normally sighted rats. Researchers say the findings suggest that a similar kind of neuroprosthesis might also help blind people walk freely through the world.

Age-discrimination during cell division maintains the 'stem' in stem cells

A team of Whitehead Institute scientists has discovered that during division, stem cells distinguish between old and young mitochondria and allocate them disproportionately between daughter cells. As a result, the daughter cell destined to remain a stem cell receives predominantly young mitochondria, while the cell meant to differentiate into another cell type carries with it a higher compliment of the aged organelles.

Algae from wastewater solves two problems

In one of the first studies to examine the potential for using municipal wastewater as a feedstock for algae-based biofuels, Rice University scientists found they could easily grow high-value strains of oil-rich algae while simultaneously removing more than 90 percent of nitrates and more than 50 percent of phosphorous from wastewater.

Bridging the gap between biodiversity data and policy reporting needs

Reporting under policy instruments to inform on the trends in biodiversity requires information from a range of different elements of biodiversity, from genetically viable populations to the structure of ecosystems. A new research looks into the Essential Biodiversity Variables as an analytic framework to identify ways in which gaps between biodiversity data and policy reporting needs could be bridged. The study was published in the Journal of Applied Ecology.

Through the grapevine: Molecular mechanisms behind Pinot berry color variation

Variations in the color of grapevine berries within the Pinot family result from naturally-occurring genetic mutations that selectively shut down the genes responsible for the synthesis of red pigments, called anthocyanins. This has led to the emergence of Pinot blanc and Pinot gris from Pinot noir. Frédérique Pelsy and her colleagues, from the "Grapevine Health and Wine Quality" research unit at INRA Colmar, France, published these findings in PLOS Genetics on 2 April 2015.

Mitochondria are altered in human cell model of Parkinson's disease

Based on research in fruit flies, it has long been suspected that the most common mutation linked to both sporadic and familial Parkinson's disease (PD) wreaks its havoc by altering the function of mitochondria in neurons that produce the neurotransmitter dopamine. Using stem cells derived from patients who have PD, scientist at the Buck Institute have confirmed that finding in human cells for the first time. In research published in the April 2nd early online edition of Stem Cell Reports, Buck researchers also provide a valuable tool for testing potential treatments for the progressive, incurable neurodegenerative disease.

An 'evolutionary relic' of the genome causes cancer

Pseudogenes, a sub-class of long non-coding RNA (lncRNA) that developed from the genome's 20,000 protein-coding genes but lost the ability to produce proteins, have long been considered nothing more than genomic "junk." Yet the retention of these 20,000 mysterious remnants during evolution has suggested that they may in fact possess biological functions and contribute to the development of disease.

Researchers create artificial link between unrelated memories

The ability to learn associations between events is critical for survival, but it has not been clear how different pieces of information stored in memory may be linked together by populations of neurons. In a study published April 2nd in Cell Reports, synchronous activation of distinct neuronal ensembles caused mice to artificially associate the memory of a foot shock with the unrelated memory of exploring a safe environment, triggering an increase in fear-related behavior when the mice were re-exposed to the non-threatening environment. The findings suggest that co-activated cell ensembles become wired together to link two distinct memories that were previously stored independently in the brain.

Services users and their needs to be at the centre of health care services

The use of technology in daily life is getting easier all the time as people accumulate knowledge and skills in information and communications technology. However, the most important thing in developing health care services, for example, is to take into account people's day to day lives and their subjective experience of the utility of using services. For example, people's previous bad experience of using a service is reflected for a long time in their use of the service in the future, and thus the dissemination of new service models is a lot slower than might be imagined. This data was the result of research carried out at Lappeenranta University of Technology, LUT.

Researchers dramatically improve ART adherence for minority PHLA

Up to 60% of persons living with HIV (PLHA) in the U.S. are neither taking antiretroviral therapy (ART) nor well engaged in HIV primary care, with racial/ethnic minorities more likely to experience barriers to engagement along this HIV continuum of care than their White counterparts. In fact, only 30% of persons living with HIV/AIDS (PLHA) in the United States have achieved "viral suppression," the ultimate goal of HIV treatment. Indeed, PLHA poorly engaged in HIV primary care and/or who are not on ART are at elevated risk for a host of poor outcomes, including more frequent hospitalizations, lower quality of life, and even earlier mortality, and also run a greater risk of transmitting HIV to their partners. Further, poor engagement in HIV care and lack of ART initiation with good adherence are major drivers of high health care costs among PLHA.
