Physics news

Supercomputing the strange difference between matter and antimatter

An international team of physicists including theorists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has published the first calculation of direct "CP" symmetry violation—how the behavior of subatomic particles (in this case, the decay of kaons) differs when matter is swapped out for antimatter. Should the prediction represented by this calculation not match experimental results, it would be conclusive evidence of new, unknown phenomena that lie outside of the Standard Model—physicists' present understanding of the fundamental particles and the forces between them.

Quantum entanglement achieved at room temperature in semiconductor wafers

Entanglement is one of the strangest phenomena predicted by quantum mechanics, the theory that underlies most of modern physics. It says that two particles can be so inextricably connected that the state of one particle can instantly influence the state of the other, no matter how far apart they are.

Ground-breaking research could challenge underlying principles of physics

An international team of physicists, including a Plymouth University academic, has published ground-breaking research on the decay of subatomic particles called kaons – which could change how scientists understand the formation of the universe.

Superfluidity in topologically nontrivial flat bands

Researchers at Aalto University have discovered that energy saving superconductors may be possible if the counterintuitive properties of electrons moving in "flat bands" are exploited.

Earth news

A whiff from blue-green algae likely responsible for Earth's oxygen

Earth's oxygen-rich atmosphere emerged in whiffs from a kind of blue-green algae in shallow oceans around 2.5 billion years ago, according to new research from Canadian and US scientists.

Trade may not help a warming planet fight its farming failures, study suggests

Warming temperatures will take a heavy toll on agricultural productivity, according to climate scientists. How will society adjust? One possibility might be increased trade: If one country suffers a decline in, say, wheat production but can still grow as much rice as ever, then—in theory—it might grow more rice and trade for its usual amount of wheat instead.

New element tracking method a boon for geoscientists

Geoscientists track how elements cycle across land, air and water to better understand climate change, ecological food webs and resources, plant nutrient cycling, water use and for forensics purposes.

2015 and 1997 El Ninos—deja vu, or something new?

El Niño: An unusually warm pool of water off the west coast of South America, usually arriving around Christmas time, linked with complex, large-scale interactions between the atmosphere and ocean in the Pacific.

A mystery that settled in stone

The strange pillarlike formation emerged after Crowley Lake reservoir was completed in 1941: stone columns up to 20 feet tall connected by high arches, as if part of an ancient Moorish temple.

Export of wood pellets from US to EU more environmentally friendly than coal

As the export of wood pellets from the U.S. to the European Union has increased six-fold since 2008, questions have been raised about the environmental impact of the practice. According to a new paper from a University of Illinois expert in environmental economics, even after accounting for factors ranging from harvesting to transportation across the Atlantic Ocean, wood pellets still trump coal by a wide margin in carbon emissions savings.

Permafrost: hiding a climate time bomb?

On the front line of climate change in the Canadian Arctic, scientists hunt for clues to a potentially catastrophic global warming trend: melting permafrost.

Great Lakes levels expected to stay mostly above average

Water levels in the Great Lakes should remain mostly above average over the next six months as a powerful El Nino gives the region a break after two bitterly cold winters, but it's unclear whether there will be longer-term effects, federal scientists said Thursday.

Sunday the day of rest for fires, study suggests

Fires are more prevalent on a Tuesday and less likely on a Sunday, according to a new University of Melbourne study, which highlights the dramatic effect humans, religion and culture have on the global climate.

'Trigger debate' over Indonesian mud volcano sheds light on dynamics of disasters

In May 2006, an underground mud volcano erupted in the East Java province of Indonesia, displacing more than 40,000 people as boiling hot mud swept into their fields and villages.

Sea traffic pollutes our lungs more than previously thought

New data presented by researchers at Lund University and others in the journal Oceanologia, show that the air along the coasts is full of hazardous nanoparticles from sea traffic. Almost half of the measured particles stem from sea traffic emissions, while the rest is deemed to be mainly from cars but also industries and natural particles from the sea.

Zooplankton growth rates key to low fish numbers

Small fisheries in Western Australian waters are at the mercy of zooplankton, with short-lived growth in the Kimberley.

Professor offers primer on energy usage and drinking water

In January 2015, the U.S. Environmental Protection Agency (EPA) estimated that a staggering $2.6 billion worth of treated drinking water is lost each year due to leaking water mains and approximately 240,000 main breaks. To address this problem, the agency proposed that more than $600 billion be invested in water infrastructure improvements over the next 20 years.

Climate change: Warm water is mixing up life in the Arctic

The warming of arctic waters in the wake of climate change is likely to produce radical changes in the marine habitats of the High North. This is indicated by data from long-term observations in the Fram Strait, which researchers from the Alfred Wegener Institute (AWI) have now analysed. Their most important finding: even a short-term influx of warm water into the Arctic Ocean would suffice to fundamentally impact the local symbiotic communities, from the water's surface down to the deep seas. As the authors recently reported in the journal Ecological Indicators, that's precisely what happened between 2005 and 2008.

Image: Extremadura, in western Spain captured by Sentinel-2A

This true-colour image of Merida was taken by Sentinel-2A on 11 August. Home to some 60 000 people, Merida is the capital of the autonomous community of Extremadura, in western Spain.

Analyzing Ross Ice Shelf radar data

The lines of data are slowly creeping across our Ross Ice Shelf GIS map and with each new line comes an improved understanding of Ross Ice Shelf. What can you learn from a 'snapshot' of data? The radar image above contains a nice story. You can see the ice thickness in the Y-axis of the annotated radar image. The ice shelf is approximately 300 meters thick. For scale this means you could stand 3 statues of liberty one on top of another and still have 21 meters of ice layered above them. The top layer on the ice shelf is snow that has accumulated on the surface of the shelf, layered almost flat as it fell on a level ice surface. Below you can see the ice that has flowed in from the Antarctic ice sheet with rumpling and roughness collected as it moved over the rougher terrain of the bed topography. Below that you can see the faint outline of the bottom of the ice shelf. This is where the radar stops, unable to image through the ocean water.

US proposes 17-year delay in start of Hanford nuclear cleanup — until 2039

Astronomy & Space news

The universe's resolution limit—why we may never have a perfect view of distant galaxies

Can you make out the dot at the bottom of this question mark? What if you stand a few metres away? The finest detail the average human eye can distinguish is about the size of a full stop seen at a distance of a metre. This is called "resolution". The best resolution for an optical system – like the eye – is roughly given by the ratio of the wavelength of the light you're viewing in and the size of the aperture that light is passing through.

Supermodel Aussie finches do a sexy DNA swap at hotspots like we do

When we mammals produce egg and sperm, our chromosomes like to swap bits of DNA so that our children actually possess new genetic combinations, helping to keep our genetics diverse and our species healthy. These DNA swapping events tend to occur in 'hotspots' in mammals because of a protein called PRDM9 that assists the swapping process in these areas. Now, an international study with Macquarie researchers, being published in the journal Science, has found that two different species of Australian finch share similar DNA swapping hotspots as well, even though they lack the PRDM9 protein.

Tomato domestication decelerated the circadian clock

All organisms, from bacteria to humans, exhibit endogenous rhythms controlled by the circadian clock. These rhythms are important for synchronization with the environment. Scientists at the Max Planck Institute for Plant Breeding Research in Cologne were able to show that the circadian clock of the cultivated tomato slowed during domestication. This deceleration is likely an adaptation to the long summer days that the cultivated species encountered as it was carried away from the equator.

Shaping contraction

You were once a hollow shell. To sculpt that hollow ball into an organism with layers of internal organs, muscle and skin, portions of that embryonic 'shell' folded inwards. The same happens to fruit fly embryos, and researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have now identified a particular group of cells which are crucial for the first such fold. They also showed for the first time that the shape in which cells are arranged determines the direction in which they contract. Published today in Developmental Cell, the findings were obtained thanks to a new technique in which the scientists use a laser as a remote control.

How fast you move can predict how healthy you'll be

Instead of focusing on drawing out the length of life, South Korea's IBS Center for Plant Aging Research and the research group led by Coleen Murphy, a professor at Princeton University have created a tool that can be used for accurately predicting lifespan as well as assessing the current health state, and discovered the regulatory mechanism that extends "healthspan", the time in which an organism is at its optimal health.

Surprising signal to control male fertility

Signaling molecules of the Wnt family are ubiquitous in biology. From cnidaria to man, they are responsible for forming the basic shape of all organisms. Without Wnt, our body would not have a top or bottom, front or rear. In addition, Wnt controls numerous other development processes in the body. Overly active Wnt signaling, on the other hand, promotes carcinogenesis.

Children's developing concept of truth and lies and the implications for child witness testimony

Recently, Dr. Victoria Talwar's 4-year-old was caught standing in suspicious circumstances. He was hiding behind the pantry door, but when questioned about what he was doing, he took on an air of complete innocence. "Were you eating one of the cookies?" –one of the forbidden cookies that he had been told he could not have. The 4-year-old shook his head "No!" but there was a chocolate smear around his lips. When questioned about these marks on his face, the 4-year-old paused and his mind feverishly searched for a reply. Finally, the answer came in a sigh "Dirt! I'm just dirty mummy!" Although Dr. Talwar did not smile then, she had to chuckle later. Playing out in her kitchen was a scene she has seen a thousand times before in her research lab at McGill.

Influenza vaccine had no affect on fetal mortality risk

Exposure to toxic stress in childhood linked to risky behavior and adult disease

How a mother responds to her baby's cries can make a big difference in the child's ability to learn, develop, and thrive. While a warm, supportive response can help the baby calm down and feel secure, a distant or angry reaction leaves the child to fend for herself in a scary world. Over time, the lack of nurturing in the face of adversity in childhood can contribute to "toxic stress"—a harmful level of stress that can affect the child's well-being well into adulthood.

What is Lewy body dementia, which robbed robin williams of his sanity?

Oscar-winning actor and comedian Robin Williams died in August 2014 of suicide. His death was not due to substance abuse or suicidal tendencies, as some had speculated in the media.

Researchers identify molecular link between schizophrenia and diabetes risk

It has long been known that psychiatric disorders, such as schizophrenia, have been associated with a higher risk of type 2 diabetes. In a new study published online in The FASEB Journal, a UMass Medical School research team, led by Rita Bortell, PhD, research professor of molecular medicine and Agata Jurczyk, PhD, instructor in molecular medicine, found that a shared gene (or genes) may underlie the co-occurrence of both diseases. Mutations in Disrupted in Schizophrenia 1 (DISC1) have been strongly associated with major psychiatric disorders, including schizophrenia, but not diabetes. This study presented the first evidence to indicate that the DISC1 gene also plays a novel, unexpected role in pancreatic beta cell survival and function. It is also the first to provide a molecular link for a prevalence of type 2 diabetes in individuals with psychiatric disorders.

High frequency stimulation in pain medicine

Due to disease-related changes in their brain, pain patients often suffer from an impaired tactile ability in their hands. In a pilot study conducted by scientists at the Ruhr-University Bochum, high frequency repetitive stimulation was investigated as a therapeutic approach for these patients. The results of this study have now been published in the journal Frontiers in Neurology. They show that passive stimulation of this kind is a promising new therapy option.

Can stem cell technology be harnessed to generate biological pacemakers?

Although today's pacemakers are lifesaving electronic devices, they are limited by their artificial nature. For example, their parts can fail or they can become infected. In addition, the devices require regular maintenance, must be replaced periodically, and can only approximate the natural regulation of a heartbeat. A Review article published on November 20 in Trends in Molecular Medicine highlights the promise and limitations of new methods based on stem cell and reprogramming technologies to generate biological pacemakers that might one day replace electronic pacemakers.

WIC program usage reviewed in new interim report

Women and children who participate in the WIC program have low or inadequate intakes of several key nutrients that could be addressed with changes to the program's food packages, says a new report from the National Academies of Sciences, Engineering, and Medicine. The report is the first in a two-phase study that reviews the current food packages in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) program. This interim report presents a series of findings and conclusions and establishes a set of criteria and a framework that will guide the second phase of the study in which changes to the WIC food packages will be considered. Recommendations for the food packages will be presented in the study's final report, which will build upon the 2006 Institute of Medicine report WIC Food Packages: A Time for Change.

The rush to calculus is bad for students and their futures in STEM

Two years ago I taught a section of Calculus I to approximately 650 undergrad students in a large auditorium. Perhaps "taught" isn't the right word. "Performed," maybe? Unsurprisingly, my student evaluation scores were not as high as they usually are in my more typical classes of 35 students, but I do remember one comment in particular: "This class destroyed my confidence." According to a new report from the Mathematical Association of America (MAA), this outcome is common, even among students who successfully completed a calculus course in high school. So what is going on?
