Near-universal T cell immunity towards a broad range of bacteria
Typically T cells of the immune system respond to a specific feature (antigen) of a microbe, thereby generating protective immunity. Scientists have discovered an exception to this rule. Namely, a group of divergent bacterial pathogens, including pneum…
Researchers find rhythmic brain activity helps to maintain temporary memories
New research shows that rhythmic brain activity is key to temporarily maintaining important information in memory. Researchers found brain rhythms — or patterns of neuronal activity — organize the bursts of activity in the brain that maintain short-t…
Ocean ecosystem: Mixotrophic microorganisms play key role
Researchers have identified a previously unknown group of bacteria, called UBA868, as key players in the energy cycle of the deep ocean. They are significantly involved in the biogeochemical cycle in the marine layer between 200 and 1000 meters.
Astrophysicists reveal the nature of dark matter through the study of crinkles in spacetime
Astrophysicists have provided the most direct evidence yet that Dark Matter does not constitute ultramassive particles as is commonly thought but instead comprises particles so light that they travel through space like waves. Their work resolves an out…
Mysterious underwater acoustic world of British ponds revealed in new study
The previously hidden and diverse underwater acoustic world in British ponds has been uncovered by a team of researchers.
CO2 recycling: What is the role of the electrolyte?
The greenhouse gas carbon dioxide can be converted into useful hydrocarbons by electrolysis. The design of the electrolysis cell is crucial in this process. The so-called zero-gap cell is particularly suitable for industrial processes. But there are st…
Jellyfish-like robots could one day clean up the world’s oceans
Roboticists have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling…
Antimicrobial use in agriculture can breed bacteria resistant to first-line human defenses
A new study has shown that overuse of antimicrobials in livestock production can drive the evolution of bacteria more resistant to the first line of the human immune response. Bacteria that had evolved resistance to colistin, an antimicrobial widely us…
Horses living in groups are better at following human indications than horses living in individual paddocks
A new study shows that horses living in big enclosures and in groups of at least three horses are better at following directional indications from humans than horses kept in individual paddocks. The results also indicate that familiarity to the human p…
Scientists demonstrate unprecedented sensitivity in measuring time delay between two photons
A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. This breakthrough has significant implications for a range of applications, including more feasible imaging of n…
