An international team of researchers, led by Professor Jin Wu from the School of Biological Sciences at The University of Hong Kong (HKU), has made a promising advancement in mapping plant functional traits from space using time-series satellite data.....»»
Are Titan"s dunes made of comet dust?
A new theory suggests that Titan's majestic dune fields may have come from outer space. Researchers had always assumed that the sand making up Titan's dunes was locally made, through erosion or condensed from atmospheric hydrocarbons. But researchers.....»»
The effects of climate variability on children"s migration and childcare practices in sub-Saharan Africa
Shifting weather caused by climate change, especially drought and heat, is linked to a rise in the number of children being raised outside of their biological parents' households in sub-Saharan Africa, according to a study led by researchers at Penn.....»»
CEOs" human concern translates into higher stock price, says study
Compassionate leadership has tangible benefits: CEOs' expressions of empathy correlate with positive stock performance, a study led by the University of Zurich shows. The researchers analyzed data from conference calls between CEOs and financial anal.....»»
Dense network of seismometers reveals how the underground ruptures
The idea that earthquakes release stress by a single strong quake along a single fault plane may need to be corrected. A recent study by researchers from the Karlsruhe Institute of Technology (KIT) with the participation of the GFZ German Research Ce.....»»
Researchers train a bank of AI models to identify memory formation signals in the brain
An international research collaboration between Vanderbilt University and the Madrid-based de la Prida lab in the Cajal Institute led to the development of AI models that detect and analyze hippocampal ripples, which are considered biomarkers of memo.....»»
Researchers crack mystery of swirling vortexes in egg cells
Egg cells are the largest single cells on the planet. Their size—often several to hundreds of times the size of a typical cell—allows them to grow into entire organisms, but it also makes it difficult to transport nutrients and other molecules ar.....»»
Researchers investigate three star-forming regions, identify hundreds young stellar objects
Using data from various space telescopes and astronomical surveys, Armenian researchers have investigated three star-forming regions. The study identified hundreds of young stellar objects and provided important information regarding the stellar cont.....»»
Capturing DNA origami folding with a new dynamic model
Most people are familiar with the DNA double-helix. Its twisted ladder shape forms because the long pieces of DNA that make up our genome are exactly complementary—every adenine paired to a thymine, and every cytosine paired to a guanine. Sequences.....»»
Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation
Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species due to its redox inertnes.....»»
Researchers reveal a hidden trait in Mycobacterium genomes governing stress adaptation
A new study, led by Qingyun Liu, Ph.D., assistant professor in the Department of Genetics, has uncovered a genetic feature known as "transcriptional plasticity," which plays a pivotal role in governing the transcriptional response of Mycobacteria to.....»»
Researchers create nanomembrane to increase reaction rate in chemical production
Flow-through reactors packed with enzymes can produce certain chemicals in a gentle and careful way. However, their performance has so far been limited. A research team from the Helmholtz-Zentrum Hereon and RWTH Aachen University has now been able to.....»»
How insects control their wings: The mysterious mechanics of insect flight
Many of us would love the superpower to fly, and for good reason: Flight offers a crucial evolutionary advantage. Flying enables an animal to travel large distances quickly, in search of food and new habitats, while expending far less energy than wal.....»»
Training of brain processes makes reading more efficient
A team of researchers from the University of Cologne and the University of Würzburg have found in training studies that the distinction between known and unknown words can be trained and leads to more efficient reading. Recognizing words is necessar.....»»
