Researchers measure tritium production rates in mock-up of water-cooled ceramic breeder blanket

Researchers measure tritium production rates in mock-up of water-cooled ceramic breeder blanket
2021-06-01
(Press-News.org) To realize tritium self-sustaining cycle through tritium breeding blanket has been one of the core technologies of future fusion reactor. Therefore the design and function of blanket must be validated by neutronic experiment under D-T neutron environment. But due to the scarcity of DT neutron source, and highly radioactivity during neutronic experiments, it is very difficult to validate the nuclear response of the blanket, the data of tritium production rate mainly rely on Monte Carlo simulation.

Recently, a research group led by ZHU Qingjun from Institute of Plasma Physics, Hefei Institutes of Physical Science (HFIPS), made progress in the experimental research on tritium production of fusion blanket mock-up, and obtained the experimental data of tritium production rate.

The program was launched five years ago, aiming at evaluating the nuclear performance of each blanket, by irradiating mock-ups at the DT neutron source. In this research, the team manufactured a water-cooled ceramic breeder blanket mock-up. They also carried out the neutronic experiment and achieved first-hand data with it.

It's proved that the experiments were in good agreement with the simulations. Considering the design margin, it fully met the requirements of tritium self-sustaining for future fusion reactor, which provided the corresponding theoretical and experimental basis for the engineering realization of breeding blanket.

Memory, learning and decision-making studied in worms

2021-06-01
As anyone who has ever procrastinated knows, remembering that you need to do something and acting on that knowledge are two different things. To understand how learning changes nerve cells and leads to different behaviors, researchers studied the much simpler nervous system of worms. "In this study, we can now translate neuronal activity to behavioral response," said Project Researcher Hirofumi Sato, a neuroscientist at the University of Tokyo and first author of the research paper recently published in Cell Reports. The discovery was made possible using technology that researchers describe as a "robot microscope," first developed in 2019 by researchers at Tohoku University in Miyagi Prefecture, northeastern Japan. The technique involves genetically modifying the worms ...

Small 'snowflakes' in the sea play a big role

Small snowflakes in the sea play a big role
2021-06-01
A team of scientists from the Max Planck Institute for Marine Microbiology, the Max Planck Institute for Meteorology and the GEOMAR - Helmholtz Centre for Ocean Research Kiel have been studying biogeochemical processes in the oxygen minimum zone of the eastern South Pacific off Peru, one of the largest low oxygen regions of the world ocean. The researchers focused on so-called marine snow particles of different sizes, which are composed of algal debris and other organic material, aiming to understand how these particles affect the nitrogen cycle in the oxygen minimum zone. Thereby, they solved ...

Infection with human papillomavirus linked to higher risk of preterm birth

2021-06-01
Women carrying human papillomavirus (HPV) run an elevated risk of preterm birth, a University of Gothenburg study shows. A connection can thus be seen between the virus itself and the risk for preterm birth that previously has been observed in pregnant women who have undergone treatment for abnormal cell changes due to HPV. A Swedish study now published in the high-ranking journal PLOS Medicine comprises data on more than a million births. Accordingly, the researchers have compared very large groups. They emphasize that the findings do not support any assessment of risk ...

Intratumoral SIRPalpha-deficient macrophages activate tumor-specific cytotoxic T cells

2021-06-01
In a study that will be published in Nature Communications on May 28, 2021, a research team led by Dr. Yuan Liu from Georgia State University reports that intratumoral SIRPα-deficient macrophages activate tumor antigen-specific cytotoxic T cells to eliminate various syngeneic cancers under radiotherapy. As a major component of the suppressive tumor microenvironment, tumor-associated macrophages (TAMs) are generally regarded as facilitators of tumor progression. It has been shown that depleting TAMs can enhance the response of tumors to radiotherapy (RT). However, Yuan's ...

Being born very preterm or very low birthweight is associated with continued lower IQ performance into adulthood

2021-06-01
The average IQ of adults born very preterm or very low birth weight was compared to those who were term born in the 1970s to 1990s in 8 longitudinal cohorts from 7 countries around the world The IQ was significantly lower for very pre-term and very low birth weight adults in comparison to those term born, researchers from the University of Warwick have found Action needs to be taken to ensure support is available for those born very preterm or very low birth weight The average IQ of adults who were born very preterm (VP) or at a very low birth weight (VLBW) has been compared to adults born full term by researchers from the Department of Psychology at the University of Warwick. Researchers have found VP/VLBW children may require special ...

Genetic treasure trove for malaria researchers

Genetic treasure trove for malaria researchers
2021-06-01
A new extensive genetic resource of rat-infecting malaria parasites may help advance the development of malaria prevention and treatment strategies. This trove of genome and phenome information has been published1 by a team of KAUST researchers, along with colleagues in Japan, and the datasets have been made publicly available for malaria researchers. Rodent malaria parasites are closely related to human parasites but are easier to study because they can be grown in laboratory mice. "Investigations on rodent malaria parasites have played a key role in revealing many aspects of fascinating biology across ...

Looking at future of Antarctic through an Indigenous Māori lens

2021-06-01
It is time for the management and conservation of the Antarctic to begin focusing on responsibility, rather than rights, through an Indigenous Māori framework, a University of Otago academic argues. In an article published in Nature Ecology & Evolution, Associate Professor Priscilla Wehi, of the Centre for Sustainability, says now is the time to be thinking of these potential changes. "New Zealand is currently re-setting its priorities for future Antarctic research, and there may be review of the current international environmental conventions as we approach the 50-year anniversary of the protocols in 2048. "We argue that Indigenous Māori frameworks offer powerful ways of thinking about how we protect the Antarctic, by focusing on ...

Biologists find invasive snails using new DNA-detection technique

Biologists find invasive snails using new DNA-detection technique
2021-06-01
Invasive species, beware: Your days of hiding may be ending. Biologists led by the University of Iowa discovered the presence of the invasive New Zealand mud snail by detecting their DNA in waters they were inhabiting incognito. The researchers employed a technique called environmental DNA (eDNA) to reveal the snails' existence, showing the method can be used to detect and control new, unknown incursions by the snail and other invasive species. "eDNA has been used successfully with other aquatic organisms, but this is the first time it's been applied to detect a new invasive population of these snails, which are a destructive invasive species in fresh waters around the world," says Maurine Neiman, associate professor in the Department ...

Rush researchers develop new measure of brain health

2021-06-01
How old is your brain compared to your chronological age? A new measure of brain health developed by researchers at Rush University Medical Center may offer a novel approach to identifying individuals at risk of memory and thinking problems, according to research results published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association on June 1. Dubbed the "cognitive clock" by the researchers, the tool is a measure of brain health based on cognitive performance. It may be used in the future to predict the likelihood of memory and thinking problems that develop ...

Unprecedented data sharing driving new rare disease diagnoses in Europe

Unprecedented data sharing driving new rare disease diagnoses in Europe
2021-06-01
Rare disease experts detail the first results of an unprecedented collaboration to diagnose people living with unsolved cases of rare diseases across Europe. The findings are published today in a series of six papers in the European Journal of Human Genetics. In the main publication, an international consortium, known as Solve-RD, explains how the periodic reanalysis of genomic and phenotypic information from people living with a rare disease can boost the chance of diagnosis when combined with data sharing across European borders on a massive scale. Using this new approach, a preliminary reanalysis of data from 8,393 individuals resulted in 255 new diagnoses, some with atypical manifestations of known diseases. A complementary study ...
