Physics news

Physicists find ways to increase antihydrogen production

(Phys.org)—There are many experiments that physicists would like to perform on antimatter, from studying its properties with spectroscopic measurements to testing how it interacts with gravity. But in order to perform these experiments, scientists first need some antimatter. Of course, they won't be finding any in nature (due to antimatter's tendency to annihilate in a burst of energy when it comes in contact with ordinary matter), and creating it in the lab has proven to be very technically challenging for the same reasons.

Shedding new light on 175-year-old principle: New class of swelling magnets have the potential to energize the world

A new class of magnets that expand their volume when placed in a magnetic field and generate negligible amounts of wasteful heat during energy harvesting, has been discovered by researchers at Temple University and the University of Maryland.

More sperm cells may be needed to overcome high mortality rate

It's one of the true miracles of life, that moment when hundreds of little sperm make it all the way to an unfertilized egg and one breaches its walls.

Tiny grains of lithium dramatically improve performance of fusion plasma

Scientists from General Atomics and the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have discovered a phenomenon that helps them to improve fusion plasmas, a finding that may quicken the development of fusion energy. Together with a team of researchers from across the United States, the scientists found that when they injected tiny grains of lithium into a plasma undergoing a particular kind of turbulence then, under the right conditions, the temperature and pressure rose dramatically. High heat and pressure are crucial to fusion, a process in which atomic nuclei - or ions - smash together and release energy—making even a brief rise in pressure of great importance for the development of fusion energy.

Amazing microdroplet structures may lead to new technologies

Unexpected shapes of mesoscale atoms—structures built of microdroplets encapsulated within microdroplets—have been created at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, Poland. The discovery was possible with a new method for precise control over placement of tiny segments of liquid, one in another. With further progress in innovative microfluidic systems, the method may find use in medicine and materials science.

New clues for the long-term viability of geological carbon dioxide storage

The carbon dioxide (CO2) at the Bravo Dome gas field in New Mexico is volcanic in origin, and its emplacement began more than a million years ago, not 10 thousand years ago, as previously estimated. Averaged across the reservoir, only 20% of the CO2 has dissolved into the field's saline brine over 1.2 million years, while the rest remains as a free gas trapped by the cap-rock, suggesting that safe long-term storage in geological sites is viable.

Brains, Genes, and Primates: The future of higher research on the planet of the apes

(Phys.org)—'Brains, Genes, and Primates' is the title of a curious perspective article recently published in the journal Neuron. In it, a who's who of dignitaries and luminaries from the field of neuroscience toss out a life raft to the now ailing vocation that has operated under the umbrella of 'primate neurophysiology'. Beginning with an eclectic mix of primate-exclusive features and skillsets, the authors make the case for the continued necessity of nonhuman primates as essential models for studying the human brain. That salvation comes via the extension to the primate realm of the ability to manipulate the genome and subsequent evo-development of rodents with godlike prowess.

Mountain gorilla mamas sidestep having inbred offspring

Some mountain gorilla females linger into adulthood in the group into which they were born. In the process they also remain in the company of their father, who is often their group's dominant male. To curb inbreeding, though, they appear to tactically avoid mating with their fathers. This strategy works so well that the chances of alpha gorilla males siring the offspring of their own daughters are effectively zero, according to Linda Vigilant of the Max Planck Institute for Anthropology in Germany. The findings are published in Springer's journal Behavioral Ecology and Sociobiology.

One simple molecule regulates sexual behavior in Drosophila

The common vinegar fly Drosophila melanogaster is a very well-studied animal. For decades, the fly has been used as a model organism in genetic research; its genome was fully sequenced in 2000. However, until now researchers have failed to identify the specific pheromone in this species that leads to mating success. Although the pheromones that inhibit mating in Drosophila were known, the positive pheromone signal that elicits courtship behavior and mating remained a mystery. Scientists from the Max Planck Institute for Chemical Ecology in Jena, Germany, have succeeded in identifying a relatively simple molecule that is able to regulate complex mating behavior in vinegar flies: a fatty acid methyl ester called methyl laurate. Verification was a result of the combination of state-of-the-art chemical analytic techniques, physiological measurements in the fly brain, and behavioral assays.

Clever fish around the coast of Mallorca Island

To avoid overfishing and aid in sustainable exploitation, the status of the fish stocks has to be monitored regularly. In many cases stock assessment is based on fishery-dependent data generated from fish markets or creel surveys. The assumption is: the lower the catches in a certain unit of time, the smaller the stock of fish should be. The scientists Dr. Josep Alós and Prof. Dr. Robert Arlinghaus from the German Leibniz-Institute of Freshwater Ecology and Inland Fisheries and the Humboldt-Universität zu Berlin have now shown that some fish species show enhanced gear-avoidance behaviour in regions with high angling intensity compared to fish exposed to low levels of exploitation near marine protected areas. The consequence is the impression that there are less fish in the sea, which does not necessarily agree with underwater reality.

Dr. Jekyll & Mr. Hyde: Telomere and telomerase in stem cells

When a human cell divides, its daughter cells should each receive an identical copy of the mother cell's genome. Occasionally mistakes occur during this process, generating mutations that can give rise to cancer. To avoid detrimental outcomes for the organism, cells with mutations that generate deviations from the normal chromosomal number are eliminated by cellular protection mechanisms. Researchers from the Leibniz Institute for Age Research – Fritz Lipmann Institute (Jena, Germany) have now identified a crucial role of telomeres, the end structures of chromosomes, for sensing cells with an incorrect chromosome number, referred to as aneuploidy. Telomeres respond to aneuploidy by generating stress signals that suppress the proliferation of aneuploid cells. However, telomerase, the enzyme, which can synthesize telomeres, may also support the survival of aneuploid cells by alleviating telomere-induced stress signals in response ! to aneuploidy. Thus, it promotes carcinogenesis instead of preventing it.

Study sheds new light on the impact of video gaming on the brain

A new study published in the journal Proceedings of the Royal Society B by the teams of Dr. Gregory West (Assistant Professor at the Université de Montréal) and Dr. Véronique Bohbot (Douglas Institute researcher and associate Professor at McGill University and the Douglas Research Institute of the CIUSSS de l'Ouest-de-l'Île de Montréal) shows that while video game players (VGPs) exhibit more efficient visual attention abilities, they are also much more likely to use navigation strategies that rely on the brain's reward system (the caudate nucleus) and not the brain's spatial memory system (the hippocampus). Past research has shown that people who use caudate nucleus-dependent navigation strategies have decreased grey matter and lower functional brain activity in the hippocampus.
