Richard Stefl from CEITEC Masaryk University (MU) and Petr Svoboda from the Institute of Molecular Genetics of the Czech Academy of Sciences (IMG CAS) and their colleagues have revealed the unique mechanism of action of mammalian Dicer.
This circuit, which weakens with age, could offer a target to help prevent age-related decline in spatial memory.
Researchers at the University of Helsinki have developed a new, faster and more reliable technique for reverting human cells to the stem cell state. Pluripotent stem cells are a key tool in biomedicine for modelling various diseases and developing novel therapies.
Modeling study suggests that the muffled environment in utero primes the brain’s ability to interpret some types of sound.
On Thursday the 27th of January 2022, M.Sc. Chen He defends her doctoral thesis on Entity-Based Insight Discovery in Visual Data Exploration. The thesis is related to research done in the Department of Computer Science and in the Ubiquitous Interaction group.
By studying the dynamics of plasma turbulence, MIT researchers are helping to solve one of the mysteries of the origins of cosmological magnetic fields.
Permafrost has a central role in the sustainable development of the Arctic region. The thaw of permafrost is set to damage buildings and roads, leading to tens of billions of euros in additional costs in the near future, according to an international review coordinated by Finnish geographers.
New findings may help explain how Earth’s crust forms, the location of ore deposits, and why some volcanoes are more explosive than others.
A molecule developed by researchers at the University of Helsinki can inactivate the coronavirus spike protein and offers effective short-term protection against the virus.
Egg white is one of the most important protein ingredients for the food industry. Egg white protein – ovalbumin – produced by precision fermentation reduced land use requirements by almost 90 per cent and greenhouse gases by 31–55 per cent compared to the production of its chicken-based counterpart.
Today (September 27, 2022) at 1:14 AM CEST NASA’s Double Asteroid Redirection Test (DART) spacecraft successfully conducted the world’s first full-scale planetary defense test by impacting asteroid moonlet Dimorphos (Greek for “two forms”), which orbits a larger asteroid named Didymos (Greek for “twin”). The kinetic impact demonstrated one possible method of asteroid deflection technology. As a part of an international planetary defense strategy, the DART mission proved that a spacecraft can autonomously navigate to a target asteroid and intentionally collide with it to alter its orbit. DART is accompanied by a small Italian sub-spacecraft called LICIACube, which observed the impact from a distance.
Two types of tau proteins mix together in a nearly random way to generate the tangles seen in the brains of Alzheimer’s patients.
A new protein that plays a key role during sperm-egg adhesion and fusion has been discovered by an international team led by Kateřina Komrsková from the Institute of Biotechnology of the Czech Academy of Sciences at the BIOCEV Centre and the Faculty of Science of Charles University in Prague. The researchers also developed special cell cultures for the “production” of human oocyte proteins. In the future, these new findings may help in the diagnosis and treatment of infertility and could also lead to better contraceptives.
When coated onto plastic tubing, the catalysts could act on chemicals flowing through, helping to synthesize drugs and other compounds.
Unexpected outcomes trigger release of noradrenaline, which helps the brain focus its attention and learn from the event.
Tested using a new brain tissue model, the particles may be able to deliver chemotherapy drugs for glioblastoma.
An extensive series of experiments has been carried out by researchers from the Institute of Plasma Physics of the CAS and the international ITER project, which aims to start producing clean and almost inexhaustible energy through the so-called tokamak within the next four years. For the first time, scientists have been able to provide experimental evidence of a physical limit to the electric currents flowing between the plasma and the first reactor wall at a time when the plasma is unstable. The new findings, published in the Nuclear Fusion journal, will help improve computer models for future fusion reactors.
MIT research highlights the opportunity to rethink global air quality guidelines.
Targeting these circuits could offer a new way to reverse motor dysfunction and depression in Parkinson’s patients.
Jonathan Weissman and collaborators used their single-cell sequencing tool Perturb-seq on every expressed gene in the human genome, linking each to its job in the cell.
