Ancient fish that ate humans’ ancestors discovered Researchers have excavated the remains of a giant ancient bony fish species with fangs from about 350 million years ago in what is now South Africa. The findings, published in the journal PLOS One, indicate that the Hyneria udlezinye species measured up to 2.7 meters long and likely […]
Gas clouds in the Cygnus X Region, a region where stars form, are composed of a dense core of molecular hydrogen (H2) and an atomic shell. These ensembles of clouds interact with each other dynamically in order to quickly form new stars. The Cygnus X region is a vast luminous cloud of gas and dust […]
Analysis of cell villages yields insight into Zika infections Studying cell villages, or samples from different donors in a shared environment, is an effective method “to identify genes and genetic variants that change a cell’s phenotype.” Scientists used the method along with the Dropulation and Census-seq algorithms to assess genetic variation in cell villages and […]
Lithium-ion batteries have remained unrivalled in terms of overall performance for several applications, as evidenced by their widespread use in everything from portable electronics to cellular base stations. However, they suffer from some important disadvantages that are difficult to ignore. For one, lithium is rather expensive, and the fact that it is being mined at […]
Astronomers puzzled by distant planet’s ring Astronomers have discovered a ring around the distant minor planet Quaoar that defies scientific understanding of how and where rings are formed. Quaoar’s ring exists in a location outside of where scientists believe particles should remain in a disk formation, prompting questions about the nature of celestial rings. Full […]
Gel-like materials that can be injected into the body hold great potential to heal injured tissues or manufacture entirely new tissues. Many researchers are working to develop these hydrogels for biomedical uses, but so far very few have made it into the clinic. To help guide in the development of such materials, which are made […]
Human brain tissue successfully implanted in rats A new study shows that balls of human brain neurons can be implanted and integrated into the brains of rats. Researchers reveal that lab-grown “human brain organoids” integrated into the rats’ brains within three months, which may pave the way for repairing injured human brains in the future […]
At the end of 2022, researchers at Lawrence Livermore National Laboratory announced they had observed a net energy gain through nuclear fusion for the very first time. This monumental milestone toward fusion energy represents a huge leap forward in powering our homes and businesses with the carbon-neutral energy source. But converting this scientific achievement into […]
Antidepressants may create antibiotic resistance Antidepressants may cause bacteria to become resistant to antibiotics, according to a study exposing the bacterium E. coli to five common antidepressants. Researchers need to further explore the effect, which was found in Petri dishes, to study whether these antidepressants can cultivate superbugs in the human body or natural environment […]
Matter outflows in the form of jets are observed in astronomical systems at fast, medium and slow speeds. The fastest jets are highly relativistic, namely travel very close to the speed of light. The origin, as well as many properties of the jets, is uncertain. One of the puzzles, that jet velocities seem to have […]
