A novel method for controlling the microstructure and performance of 3D printed human implants

Eurekalert - Jun 27 2021 - 00:06
With the rapid development of biomedical technology, the replacement of human skeletal diseases through human implants has become an application market with high technical content and huge benefits. In order to quickly customize human implants with complex structures, Chinese scientists use 3D printing technology to prepare Ti-Mo alloy human implants, and then adjust the microstructure and performance of the human implants through subsequent heat treatment, so as to obtain human implant products with excellent compatibility.

Attomolar sensing: Fabrication of surface-enhanced raman scattering substrate

Eurekalert - Jun 27 2021 - 00:06
Surface-enhanced Raman scattering (SERS) permits multidisciplinary trace analyses and the potential detection of single molecules. Shi Bai and Koji Sugioka from RIKEN report a comprehensive review of recent progress in strategies for the fabrication of highly sensitive SERS substrates. Femtosecond laser-based techniques are discussed as a versatile tool for the fabrication of SERS substrates. Several approaches are highlighted for enhancing the performance of SERS sensing devices, and real-time sensing and biological applications are reviewed.

Has the stilling of the surface wind speed ended in China?

Eurekalert - Jun 27 2021 - 00:06
The continuous weakening of global land surface wind speed (stilling) has seriously affected the ecological environment and social economy, especially restricted the sustainable development of the wind energy industry. A recent study systematically answered the question of whether the surface wind speed in China is still weakening.

Multi-material multi-photon 3D laser micro- and nanoprinting

Eurekalert - Jun 27 2021 - 00:06
Most realized 3D architectures are composed of only a single polymeric material. Here, we review 3D printing of multi-materials on the nano- and microscale. We start with material properties that have been realized, using multi-photon photoresists. Next, we review manual and automated processes achieving dissimilar material properties in a single 3D structure by sequentially photo-exposing multiple photoresists and by controlled stimuli of a single photoresist. Instructive examples from biology, optics, mechanics, and electronics are discussed.

Small p values may not yield robust findings: An example using REST-meta-PD

Eurekalert - Jun 27 2021 - 00:06
A large number of articles have been published using resting-state functional magnetic resonance imaging for clinical research, and almost all the results survived multiple comparisons correction, a standard procedure performed to reduce false positive rates. Now the researchers from more than 20 worldwide groups have found that in individual studies with small sample sizes, a smaller p value reduced true positive effect and did not save the reproducibility of true effects.

Coral enhance its environmental adaptability by adjusting trophic status

Eurekalert - Jun 27 2021 - 00:06
Under the background of global warming and the increasing impact of human activities, the phenomenon of coral bleaching is becoming more and more serious. Scleractinian coral as mixotrophic organisms, but it is unclear about the impact of trophic flexibility on their environmental adaptability. Recent studies have revealed that coral could enhance its environmental adaptability by adjusting trophic status. This discovery was reported in the cover article of "SCIENCE CHINA: Earth Sciences", Issue 6, 2021.

AI learns to predict human behavior from videos

Eurekalert - Jun 27 2021 - 00:06
New Columbia Engineering study unveils a computer vision technique for giving machines a more intuitive sense for what will happen next by leveraging higher-level associations between people, animals, and objects."Our algorithm is a step toward machines being able to make better predictions about human behavior, and thus better coordinate their actions with ours," said Computer Science Professor Carl Vondrick. "Our results open a number of possibilities for human-robot collaboration, autonomous vehicles, and assistive technology."

Males help keep populations genetically healthy

Eurekalert - Jun 27 2021 - 00:06
A few males are enough to fertilize all the females. The number of males therefore has little bearing on a population's growth. However, they are important for purging bad mutations from the population. This is shown by a new Uppsala University study providing in-depth knowledge of the possible long-term genetic consequences of sexual selection. The results are published in the scientific journal Evolution Letters.

Toxicity of protein involved in Alzheimer's triggered by a chemical 'switch'

Eurekalert - Jun 26 2021 - 00:06
Tokyo, Japan - Researchers from Tokyo Metropolitan University have discovered that a specific chemical feature of a key protein known as tau may cause it to accumulate in the brain and trigger illnesses like Alzheimer's. They found that disulfide bonds on certain amino acids act to stabilize tau and cause it to accumulate, an effect that got worse with increased oxidative stress. The identification of chemical targets triggering tau accumulation may lead to breakthrough treatments.

Impact of cocoa agroforestry on bird diversity

Eurekalert - Jun 25 2021 - 00:06
An estimated 2-3 million hectares of tropical forest were converted to cocoa from 1988-2008 with severe consequences for biodiversity. Unsustainable cocoa monocultures (agricultural systems growing a single crop type) eventually collapse from disease, pests and soil degradation, hurting local communities as well as bird populations. Eliminating monoculture cocoa from supply chains and converting to sustainable agroforestry systems can help maintain productive farms while protecting habitats and biodiversity.

Edible Cholera vaccine made of powdered rice proves safe in phase 1 human trials

Eurekalert - Jun 25 2021 - 00:06
Vaccine manufacturing made enormous strides in 2020, but the complexity of SARS-CoV-2 vaccines has highlighted the value of inoculations that can be made cheaply and transported and stored without refrigeration. A new needle-free cholera vaccine has been made by grinding up genetically modified grains of rice and can be stored long-term at room temperature. This made-in-Japan innovation has shown no obvious side effects and a good immune response in its Phase 1 clinical trial.
