The philosopher’s job is surely more than to be a servant to the sciences
Every cuckoo is an adopted child—raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of female cuckoos: a gray morph that looks like a sparrowhawk, and a rufous morph. Male cuckoos are always gray.
“With this mimicry, the bird imitates dangerous predators of the host birds, so that they keep their distance instead of attacking,” says Professor Jochen Wolf from LMU Munich.
Together with researchers at CIBIO (Centro de Investigação em Biodiversidade e Recursos Genéticos, Portugal), the evolutionary biologist has investigated the genetic foundations of the variant coloring, which is limited to females and emerged over the long evolutionary arms race between host and cuckoo. The research is published in the journal Science Advances.
An international collaboration of researchers, led by Philip Walther at University of Vienna, have achieved a significant breakthrough in quantum technology, with the successful demonstration of quantum interference among several single photons using a novel resource-efficient platform. The work published in the prestigious journal Science Advances represents a notable advancement in optical quantum computing that paves the way for more scalable quantum technologies.
Interference among photons, a fundamental phenomenon in quantum optics, serves as a cornerstone of optical quantum computing. It involves harnessing the properties of light, such as its wave-particle duality, to induce interference patterns, enabling the encoding and processing of quantum information.
In traditional multi-photon experiments, spatial encoding is commonly employed, wherein photons are manipulated in different spatial paths to induce interference. These experiments require intricate setups with numerous components, making them resource-intensive and challenging to scale.
In a future with more ‘mind reading,’ thanks to computer-brain interfaces, we may need to rethink freedom of thought.
In just 2 hours, small metal robots can capture most nanoscopic plastic particles from a sample of water.
The bizarre feat can be achieved in special, two-dimensional crystals by deforming them only slightly, a new study discovered.
Cas9 nucleases hold clinical significance for genome editing therapies. Here the authors characterize CoCas9, a compact, efficient and precise Cas9 from the human microbiome, and show that delivery via AAV vectors enables efficient editing in the mouse retina, expanding the genome editing toolbox.
Scaling up qubit counts in quantum computers is at the core of achieving quantum supremacy.
Among the troublesome hurdles of this scaling-up race is refining how qubits are measured. Devices called parametric amplifiers are traditionally used to do these measurements. But as the name suggests, the device amplifies weak signals picked up from the qubits to conduct the readout, which causes unwanted noise and can lead to decoherence of the qubits if not protected by additional large components. More importantly, the bulky size of the amplification chain becomes technically challenging to work around as qubit counts increase in size-limited refrigerators.
Cue the Aalto University research group Quantum Computing and Devices (QCD). They have a hefty track record of showing how thermal bolometers can be used as ultrasensitive detectors, and they just demonstrated in an April 10 Nature Electronics paper that bolometer measurements can be accurate enough for single-shot qubit readout.
Using DNA and proteins, scientists have created new synthetic cells that act like living cells. Blurring the line between artificial and living materials, these cells can be reprogrammed to perform multiple functions, opening the door to new synthetic biology tech that goes beyond nature’s abilities.
Cells get their structure and stability from their cytoskeleton, a crosslinked framework of proteins that encases and protects other components. Depending on the type of cell, this cytoskeleton can be flexible to different degrees and respond in different ways to their environment, giving cells their specialized abilities.
For the new study, scientists from the University of North Carolina at Chapel Hill developed synthetic, self-assembling cytoskeletons, built out of DNA, peptides and other genetic material.
Researchers have developed a new technique that can “reprogram” magnetic cilia to move in new directions as needed. Magnetic cilia – an artificial hair-like structure containing embedded magnetic particles – are used frequently in soft robots, transporting objects and mixing liquids.
