đ LumenOrbit (YC S24) is building a network of megawatt-scale data centers in space, scalable to gigawatt capacity.
Why we should train AI in space.
Across all species, critical skills are passed on from parents to offspring through communication. Researchers at the University Hospital Bonn (UKB) and the Researchers at the University of Bonn showed that effective communication relies on how both the sender and receiver represent information. Their study reveals how this process underlies training efficacy and task performance. Their results have been published in the journal Nature Communications.
Communicationâbe it through sounds, smells or movementsâis crucial for survival. Its social aspect is fundamental to cognition, as our task descriptions in the brain are shaped not only by sensory experiences, but also by the information communicated to us.
âWe know from our everyday lives that social communication is essential to our learning abilities in the real world, which is summed up by the saying âteaching is learning for the second time,â says Prof. Tatjana Tchumatchenko, from the Institute of Experimental Epileptology and Cognition Research at the UKB and member of the Transdisciplinary Research Area (TRA) âModellingâ at the University of Bonn.
The achievement marks a way toward âfault-tolerantâ quantum computing as it achieved record-low error rates in prototype quantum computer. Itâs also expected to lead to the development of more stable quantum computers.
IQM maintains that qubit relaxation time T1 of 0.964 +- 0.092 milliseconds and dephasing time T2 echo of 1.155 +- 0.188 milliseconds was demonstrated on a planar transmon qubit on a silicon chip fabricated in IQMÂŽs own fabrication facilities.
The coherence times, characterized by the relaxation time T1 and the dephasing time T2 echo, are among the key metrics for assessing the performance of a single qubit, as they indicate how long quantum information can be stored in a physical qubit, according to the company.
Tiny robots much smaller than blood cells could deliver clot-forming drugs where theyâre needed most, a study in rabbits suggests. The tech has yet to be tested in humans.
An ultra-precise measurement of a transition in the hearts of thorium atoms gives physicists a tool to probe the forces that bind the universe.
A new method for assembling neuron cultures horizontally instead of vertically helps solve for a longstanding issue.
Extracellular vesicles (EVs) or exosomes are nanosized extracellular particles that contain proteins, DNA, non-coding RNA (ncRNA) and other molecules, which are widely present in biofluids throughout the body. As a key mediator of intercellular communication, EVs transfer their cargoes to target cells and activate signaling transduction. Increasing evidence shows that ncRNA is involved in a variety of pathological and physiological processes through various pathways, particularly the inflammatory response. Macrophage, one of the bodyâs âgatekeepersâ, plays a crucial role in inflammatory reactions. Generally, macrophages can be classified as pro-inflammatory type (M1) or anti-inflammatory type (M2) upon their phenotypes, a phenomenon termed macrophage polarization.
Proposed experiments will search for signs that spacetime is quantum and can exist in a superposition of multiple shapes at once.

There is a glaring gap in our knowledge of the physical world: none of our well-Âestablished theories describe gravityâs quantum nature. Yet physicists expect that this quantum nature is essential for explaining extreme situations such as the very early universe and the deep interior of black holes. The need to understand it is called the problem of âquantum gravity.â
Researchers have discovered that DNA methylation is crucial for reprogramming astrocytes into stem cells in the adult mouse brain, especially after ischemic injury, with potential implications for regenerative medicine.
