Prenatal exposure to THC, CBD affects offspring's responsiveness to fluoxetine

A team of researchers from the University of Cambridge, University College London, University of Oxford, and University of Brescia/RFF-CMCC European Institute on Economics and the Environment carried out the first systematic analysis of the relative performance of probabilistic cost forecasts from expert-based methods and model-based methods. They specifically focused on one expert-based method -- expert elicitations -- and four model-based methods which model costs either as a function of cumulative installed capacity or as a function of time. The results of this ...

Researchers have developed a more efficient platform for studying proteins that play a key role in regulating gene expression. The approach uses engineered yeast cells to produce enzyme and histone proteins, conduct biochemical assays internally, and then display the results. "Biomedical and biotech researchers are interested in the mechanisms that allow histones to regulate gene activity," says Alison Waldman, first author of a paper on the work and a Ph.D. student at North Carolina State University. "But the conventional tools for histone research are unwieldy ...

Mass-flowering crops such as oilseed rape or faba bean (also known as broad bean) provide valuable sources of food for bees, which, in turn, contribute to the pollination of both the crops and nearby wild plants when they visit. But not every arable crop that produces flowers is visited by the same bees. A team from the University of Göttingen and the Julius Kühn Institute (JKI) in Braunschweig has investigated how the habitat diversity of the agricultural landscape and the cultivation of different mass-flowering crops affect wild bees. The research shows that diverse agricultural landscapes increase the species richness ...

A team led by Skoltech professor Artem R. Oganov studied the structure and properties of ternary hydrides of lanthanum and yttrium and showed that alloying is an effective strategy for stabilizing otherwise unstable phases YH10 and LaH6, expected to be high-temperature superconductors. The research was published in the journal Materials Today. Cuprates had long remained record-setters for high-temperature superconductivity until H3S was predicted in 2014. This unusual sulfur hydride was estimated to have high-temperature superconductivity at 191-204 K and was later obtained experimentally, setting a new record in superconductivity. Following this discovery, many scientists turned to superhydrides, which are abnormally rich in hydrogen, and discovered new compounds that ...

Laboratories are an inherent part of technology qualifications, as practical experiments are essential for students to acquire the competencies and skills that they will need during their future professional development. Providing this learning in a virtual format is one of the challenges posed by the current COVID-19 pandemic--a challenge that distance universities have been addressing for years. RLAB-UOC is a remote laboratory designed and developed by the Universitat Oberta de Catalunya (UOC) that enables students in the Faculty of Computer Science, Multimedia and Telecommunications to conduct practical experiments with real electronic and communications equipment anywhere, at any time. A new article published in the scientific journal Electronics has described the characteristics ...

Near-death experiences are known from all parts of the world, various times and numerous cultural backgrounds. This universality suggests they may have a biological origin and purpose, but exactly what this could be has been largely unexplored. A new study conducted jointly by the University of Copenhagen (Denmark) and the University of Liege (Belgium) and published in Brain Communications shows how near-death experiences in humans may have arisen from evolutionary mechanisms. "Adhering to a preregistered protocol, we investigated the hypothesis that thanatosis is the evolutionary origin of near-death experiences", says Daniel Kondziella, a neurologist from Rigshospitalet, Copenhagen University Hospital. When attacked by a predator, as a last resort defense mechanism, ...

An affordable lab system that uses grass blades to turn cells into cultured meat has been developed at the University of Bath in the UK. Researchers have successfully taken grass from the university's campus and used it to create a scaffold that animal cells can attach to and grow on. The resulting tissue has the potential to be used both as lab-made meat and as human muscle tissue to repair or replace tissue which has been damaged or lost through injury or disease. The study, by Dr Paul De Bank (Department of Pharmacy & Pharmacology), Professor Marianne Ellis (Department of Chemical Engineering) and Scott Allan (a PhD researcher in the Department of Chemical Engineering), is published in this month's Journal of ...

RUDN University chemists have proposed a new method of producing fuel from Jatropha Curcas, a poisonous tropical plant. Natural minerals and a non-toxic additive from vegetable raw materials are used for that. The reaction efficiency is 85%. The fuel can be used in diesel internal combustion engines. The results are published in the International Journal of Green Energy. Jatropha Curcas is a common plant in many tropical regions. Its seeds contain lots of oil, but they cannot be used agriculture because the oil contains toxins that are dangerous for people and animals. But the composition of jatropha oil is suitable for the manufacture of biodiesel. One of challenge of the processing the plant raw materials is to select sufficiently ...

PROVIDENCE, R.I. [Brown University] -- Researchers from Brown University and MIT have developed a new data science framework that allows users to process data with the programming language Python -- without paying the "performance tax" normally associated with a user-friendly language. The new framework, called Tuplex, is able to process data queries written in Python up to 90 times faster than industry-standard data systems like Apache Spark or Dask. The research team unveiled the system in research presented at SIGMOD 2021, a premier data processing conference, and have made the software freely available to all. "Python is the primary programming language used by people doing data science," said Malte Schwarzkopf, an assistant professor of computer ...

A collaboration led by Distinguished Professor Dr. Kazunori Ikebukuro from Tokyo University of Agriculture and Technology (TUAT), Japan, discovered that G-quadruplex (G4)-forming DNA binds myoglobin through a parallel-type G4 structure. Through the G4 binding, the enzymatic activity of myoglobin increases over 300-fold compared to that of myoglobin alone (Figure). This finding indicates that DNA may work as a carrier of genetic information in living organisms and act as a regulator of unknown biological phenomena. "Aptamers" are nucleic acid-based synthetic ligands that can be used against many target molecules with high affinity and specificity. Some aptamers that bind to proteins ...
