The design and development of novel materials with superior properties demands a comprehensive analysis of their atomic and electronic structures. Electron energy parameters such as ionization potential (IP), the energy needed to remove an electron from the valence band maximum, and electron affinity (EA), the amount of energy released upon the attachment of an electron to the conduction band minimum, reveal important information about the electronic band structure of surfaces of semiconductors, insulators, and dielectrics. The accurate ...

Scientists have discovered that a type of fat accumulates as tissue ages and that this accumulation can be reversed through exercise. Researchers from Amsterdam UMC, together with colleagues from Maastricht UMC+, analysed both mice and human tissue before and after exercise allowing them to draw this conclusion. The results are published today in Nature Aging.   "The idea that we could reverse aging is something that was long considered science fiction, but these findings do allow us to understand a lot more about the ...

In October 2022, an international team of researchers, including Northwestern University astrophysicists, observed the brightest gamma-ray burst (GRB) ever recorded, GRB 221009A. Now, a Northwestern-led team has confirmed that the phenomenon responsible for the historic burst — dubbed the B.O.A.T. (“brightest of all time”) — is the collapse and subsequent explosion of a massive star. The team discovered the explosion, or supernova, using NASA’s James Webb Space Telescope (JWST).  While this discovery solves one mystery, another mystery deepens.  The researchers ...

An international research team led by a researcher from the University of Vienna has for the first time directly detected stellar winds from three Sun-like stars by recording the X-ray emission from their astrospheres, and placed constraints on the mass loss rate of the stars via their stellar winds. The study is currently published in Nature Astronomy. Astrospheres, stellar analogues of the heliosphere that surrounds our solar system, are very hot plasma bubbles blown by stellar winds into the interstellar medium, a space filled with gas and dust. The ...

Whether by way of Attenborough, Disney or National Geographic, the iconic scene is familiar to many. The ground trembles and clouds of dust swirl as enormous hordes of large animals thunder across the African savanna, cross rivers en masse and are picked off by lions, hyena and crocodiles. The annual migration of 1.3 million wildebeest through Tanzania’s Serengeti and Kenya’s Masai Mara attracts hundreds of thousands of tourists, and the phenomenon has put the Serengeti on UNESCO's list of World Heritage sites. Besides its majestic sight, the migration of this emblematic species ...

A Dartmouth-led study suggests that people who frequently consume seafood may face an increased risk of exposure to PFAS, the family of ubiquitous and resilient human-made toxins known as "forever chemicals." The findings stress the need for more stringent public health guidelines that establish the amount of seafood people can safely consume to limit their exposure to perfluoroalkyl and polyfluoroalkyl substances, the researchers report in the journal Exposure and Health. This need is especially urgent for coastal regions such as New England where a legacy of industry and PFAS pollution bumps up against a cultural predilection for fish, the authors write. "Our recommendation ...

Softer tumours fuel more aggressive spread of triple-negative breast cancer Researchers have discovered how the mechanical properties of tumours can prime cancer cells to better survive their spread to other organs. A metabolic ‘survival switch’ controlled by the stiffness of triple-negative breast tumours can significantly influence how successfully their cancerous cells spread to other organs, according to new findings from the Garvan Institute of Medical Research. The study in cell and ...

It's interesting to hear about the research led by Minyi Guo that was published in Frontiers of Computer Science on 12 Mar 2024. It seems like they are addressing the challenge of reducing storage overhead in blockchain systems while maintaining data consistency and tolerating malicious nodes. In traditional blockchain networks, full replication is used, where each node stores a complete copy of all blocks, and data consistency is maintained through a consensus protocol. However, this approach can be storage-intensive, especially as the blockchain grows over time. To address ...

Erhai Lake, covering 252 km2, located in Yunnan Province, is one of the seven largest freshwater lakes in China. However, over the last three decades, the lake has suffered pollution episodes. In order to solve this problem, the local government has taken many protective measures. These measures have achieved some results in the environmental protection of Erhai Lake, but also caused significant socioeconomic impact. The tension between environmental preservation and economic stability in Erhai has even been termed the ‘Erhai dilemma’. The ‘Erhai dilemma’ is representative of those of other lakes in Yunnan Province ...

Assessing the function of forest ecosystems requires a deep understanding of the mechanisms of soil nitrogen mineralization. A recent study conducted by a team of researchers has shed light on how soil N-cycling genes drive soil nitrogen mineralization during afforestation. The findings, published in the prestigious journal Soil Ecology Letters, provide valuable insights into the relationship between soil microbial communities, functional genes, and the rate of soil nitrogen mineralization.   The researchers collected soil samples from a chronosequence of Robinia pseudoacacia L (RP14, RP20, RP30, and RP45) at different stages of afforestation, along with a sloped farmland (FL) as ...

Kyoto, Japan -- Mother Nature is an artist, but her craft of creating animal faces requires more than a paintbrush and palette. Such highly complex shapes originate from their respective transient neural crest cells.  These embryonic pluripotent cells within the facial primordium—the early development form—may be necessary for forming proper facial structures. However, analyzing the molecular mechanisms in such early stages of development poses many technical challenges. Now, a group of Kyoto University researchers have produced neural crest cell-rich ...

WASHINGTON (April 11, 2024) – Vosoritide’s first global phase 2 study showed an average increased growth rate of 1.8 cm per year in children with hypochondroplasia, a genetic cause of short stature in children, according to researchers from Children’s National Hospital. “This is the first medicine that has been developed to specifically target the pathway involved in hypochondroplasia,” says Andrew Dauber, M.D., chief of Endocrinology at Children’s National. “These findings will help inform future studies of vosoritide for addressing growth disorders.”  This clinical trial ...

Inside the brains of people with psychosis, two key systems are malfunctioning: a "filter" that directs attention toward important external events and internal thoughts, and a "predictor" composed of pathways that anticipate rewards. Dysfunction of these systems makes it difficult to know what’s real, manifesting as hallucinations and delusions. The findings come from a Stanford Medicine-led study, publishing April 11 in Molecular Psychiatry, that used brain scan data from children, teens and young adults with psychosis. The results confirm ...

Amaral-Zettler receives almost 3,5 million euros for her research into biodegradation in the marine environment. “Biodegradable sounds really nice”, she admits. “But before we repeat the mistakes we’ve made with fossil-fuel-based plastics back in the last millenium, we really want to understand how these materials interact with marine life and how long they last in the environment.” “Biodegradable ...

We depend on our cells being able to divide and multiply, whether it’s to replace sunburnt skin or replenish our blood supply and recover from injury. Chromosomes, which carry all of our genetic instructions, must be copied in a complete way during cell division. Telomeres, which cap the ends of chromosomes, play a critical role in this cell-renewal process—with a direct bearing on health and disease. The enzyme telomerase plays a key role in maintaining the length of telomeres as chromosomes replicate during ...

Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recent discovery upends that rule.  In two recent papers, an international team of scientists describe the first known nitrogen-fixing organelle within a eukaryotic cell. The organelle is the fourth example in history of primary endosymbiosis — the process by which a prokaryotic cell is engulfed by a eukaryotic cell and evolves beyond symbiosis into an organelle. “It’s very rare that organelles ...
