Scientists discover new mechanism involved in learning and memory
What happens inside neurons when we memorize a password or learn the cello? Some of our basic understanding about learning and memory comes from the study of conditions in which cognitive development is disrupted. For example, FMRP, a protein whose l.....»»
Multiframe imaging of micron and nanoscale bubble dynamics
The formation and collapse of microscopic bubbles is important in a wide range of fields as both a potential mechanism behind tissue damage, such as in cases of blast-wave-induced traumatic brain injury, and as a useful tool for technology applicatio.....»»
High-potential vorticity systems over Tibetan Plateau contribute to record-breaking rainfall around Yangtze River
The Yangtze River Valley experienced several disastrous rainfall events throughout the record-breaking Meiyu season in 2020. However, the mechanism of the extreme precipitation over the upper reaches of the Yangtze River remains unclear......»»
Saturn"s high-altitude winds generate an extraordinary aurorae, study finds
Leicester space scientists have discovered a never-before-seen mechanism fuelling huge planetary aurorae at Saturn......»»
Nanowires under tension create the basis for ultrafast transistors
Smaller chips, faster computers, less energy consumption. Novel concepts based on semiconductor nanowires are expected to make transistors in microelectronic circuits better and more efficient. Electron mobility plays a key role in this: The faster e.....»»
iPad calculator (sort of) provided by Google rather than Apple
Why there is no official iPad calculator app is one of the mysteries of the universe, ranking alongside “What is dark matter?” and “What is the biological mechanism for the placebo effect?” … more… The post iPad.....»»
Taiwan to boost low-carbon production to cope with EU CBAM
As the EU will enforce CBAM (Carbon Border Adjustment Mechanism) beginning 2023, the Taiwan government has established an interdepartmental task force to work out a net zero carbon emission scheme for Ministry of Economic Affairs (MOEA) to plan vario.....»»
Researchers discover new bacterial mechanism for environmental adaptation
Bacteria are extremely resourceful when it comes to adapting to a given environment. A team of researchers from Würzburg has now discovered a new trick bacteria use: a kind of sponge that absorbs certain messengers......»»
Identifying a protective mechanism against the negative consequences of ammonium fertilization
Nitrogen (N) is an essential mineral element for plant development and is widely used in crop production. While synthetic nitrogen fertilizers significantly improve global crop yields, the use of nitrate-based nitrogen fertilizers bears the risk of n.....»»
Satellite data shows "shocking" way Earth"s magnetic field produces plasma jets
Even though Earth's magnetic field shields us from solar wind and space weather, it doesn't always offer complete protection. Researchers have discovered a new mechanism in Earth's space environment that can allow solar particles to slip through the.....»»
Scientists identify geological "Goldilocks zone" for the formation of metal ore deposits
Scientists have identified a mechanism through which important metals, crucial to the manufacturing of renewable energy technologies, are passed from the Earth's mantle to the crust......»»
Underestimated ozone production in cities: Higher HOx observed with self-developed instrument
The local ozone generation was greatly underestimated with current mechanism under high NOx conditions, according to a recent study conducted by researchers led by Prof. Xie Pinhua from the Hefei Institutes of Physical Science (HFIPS) of the Chinese.....»»
Transcriptional regulation mechanism of hard clams against heat and hypoxia stress
Temperature and dissolved oxygen (DO) can affect a series of physiological and biochemical responses and drive the expression of regulatory genes. When water temperature increases, the solubility of oxygen decreases, leading to hypoxia......»»
The role of ribosomes in age-related diseases
Aging leads to a decline in cellular fitness and loss of optimal protein function. Many age-related ailments, including Alzheimer's and Parkinson's diseases, are caused by protein aggregation, a result of errors in protein folding. Yet, the mechanism.....»»
Selective membrane may cycle dual-ion batteries closer to reality
Lithium-ion batteries are relatively safe, long-lasting, fast charging and better for the environment than non-rechargeable batteries—right? Not quite. The rocking-chair mechanism that allows for commercial power storage generally uses rare earth e.....»»
Transcriptional regulatory mechanism of plant pectin biosynthesis
Pectin is a complex cell wall polysaccharide. It plays an important role in modulating cell adhesion, cell morphogenesis and growth......»»
C. elegans does not accidentally switch off its ability to detect salt
AMOLF researchers, collaborating with researchers from the Erasmus MC, have discovered a genetic mechanism that ensures that a nerve cell retains its identity once it has differentiated. This concerns a neuron in the worm C. elegans that can detect s.....»»
Scientists reveal ultrafast melting dynamics in matter heated to extreme temperatures
Ordinary matter behaves very differently when subjected to extreme temperatures and pressures, such as that inside stellar and planetary cores. Conventional rules of condensed matter physics and plasma physics are not applicable in such scenarios. In.....»»
Nonequilibrium mechanism of bacterial flagellar motor switching revealed
In work published in Physical Review Letters, a research group led by Prof. Yuan Junhua and Prof. Zhang Rongjing from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences proposed a novel nonequilibrium mechanis.....»»
Researchers reveal preservation mechanism of Chuaria fossils in Lantian biota
