A new system, developed by Tohoku University researchers in Japan in collaboration with Los Alamos National Laboratory in the US, takes 3D images that can detect defects in metallic structures. The approach was published in the journal Applied Physics Letters and could enhance safety in power plants and airplanes.
Tokyo, Japan - Researchers led by The University of Tokyo employed a new computer model to simulate the networks of force-carrying particles that give amorphous solids their strength even though they lack long range order. This work may lead to new advances in high-strength glass, which can be used for cooking, industrial, and smartphone applications.
The stroma of the choroid plexus is one of the locations within the central nervous system (CNS) that serves as a shelter for tumour cells, allowing them to elude chemotherapy and potentially cause subsequent relapses in childhood acute lymphoblastic leukaemia, according to research led by the Complutense University of Madrid (UCM).
These findings refute 150-year-old assumptions. The team, published its findings in the journal Science from 25. September 2020.
The largest brains
Birds and mammals have the largest brains in relation to their body. Apart from that, however, they have little in common, according to scientific opinion since the 19th century: mammalian brains have a neocortex, i.e. a cerebral cortex that's made up of six layers and arranged in columns perpendicular to these layers. Avian brains, on the other hand, look like clumps of grey cells.
Lifestyles in China are changing rapidly, and ordering food online is an example. However, those billions of delivery meals produce an enormous amount of plastic waste from packaging, but also from food containers and cutlery; in one year, some 7.3 billion sets of single-use tableware accompany the food. Around one-third of the 553 kilotons of municipal solid waste that is generated each day comes from packaging. That is why a group of scientists analysed whether using paper alternatives or reusable tableware could reduce plastic waste and associated life cycle emissions.
NASA's Aqua satellite provided an infrared view of Tropical Storm Lowell that revealed the effects of outside winds battering the storm.
Wind shear occurs when winds at different levels of the atmosphere push against the rotating cylinder of winds, weakening the rotation by pushing it apart at different levels.

NASA's Terra satellite obtained visible imagery of Post-Tropical Cyclone Beta as it continued moving slowly through the Tennessee Valley. Clouds associated with the low-pressure area looked like a large white blanket draped across much of the southeastern U.S.
On Sept. 25, NOAA's National Weather Service Weather Prediction Center (WPC) in College Park, Md. noted Beta was moving slowly northeast. It was centered about 60 miles (100 km) north-northeast of Birmingham, Alabama.

How many "listeners" a nerve cell has in the brain is strictly regulated. This is shown by an international study led by the University College London and the universities of Bonn, Bordeaux and Milton Keynes (England). In the environment of learning neurons, certain processes are set in motion that make signal transmission less exclusive. The results have now been published in the journal Neuron.
The PhytoFrontiers™ editorial board, led by editor-in-chief Nik Grünwald and associate editor-in-chief Steve Klosterman, is pleased to announce the publication of its first paper, "Distinct Arabidopsis responses to two generalist caterpillar species differing in host breadth," which comes from Jacquie Bede's lab at McGill University in Quebec, Canada.
HOUSTON - (Sept. 24, 2020) - Stripes are in fashion this season at a Rice University lab, where researchers use them to make images that plain cameras could never capture.
Their compact Hyperspectral Stripe Projector (HSP) is a step toward a new method to collect the spatial and spectral information required for self-driving cars, machine vision, crop monitoring, surface wear and corrosion detection and other applications.
Being traumatized can cause what are known as dissociative symptoms--such as experiencing amnesia, an out-of-body experience, feeling emotionally numb--which may help people cope. Experiencing these symptoms intensely or for a long time, however, can negatively impact an individual's ability to function.
Unlike secondary batteries that need to be recharged, fuel cells are a type of eco-friendly power generation systems that produce electricity directly from electrochemical reactions using hydrogen as fuel and oxygen as oxidant. There are various types of fuel cells, differing in operating temperatures and electrolyte materials. Among them, the solid oxide fuel cell (SOFC), which uses a ceramic electrolyte, are receiving increasing attention.
WEST LAFAYETTE, Ind. - Clostridioides difficile, or C. diff, is the leading cause of health care-associated infection in the U.S.
Only two antibiotics, vancomycin and fidaxomicin, are FDA approved for the treatment of C. diff, but even these therapies suffer from high treatment failure and recurrence.
Topology-optimized thermal cloak-concentrator realizes excellent cloaking and concentrating simultaneously although it is built of a simple composition. The thermal cloak-concentrator is not so easily effected by fluctuations of thermal conductivity and is designed by incorporating multiple objective functions under various thermal conductivities.
The white, fluffy layer that covers Camembert is made of a mould resulting from human selection, similar to the way dogs were domesticated from wolves. A collaboration involving French scientists from the CNRS* has shown, through genomic analyses and laboratory experiments, that the mould Penicillium camemberti is the result of a domestication process that took place in several stages. According to their work, a first domestication event resulted in the blue-green mould P. biforme, which is used, for example, for making fresh goat's cheese.
