At the smallest scales, everything is made out of a cloud of quantum possibilities. A new idea attempts to explain how our everyday world comes from this, using the laws of thermodynamics.

Barry-1 has 2 Quantum Drives: QD1 (Blue Arrow, internal) & QD1-TC (Green Arrow). Both are designed to produce thrust in the same direction (Red Arrow). QD1-TC is expected to produce about 2x the thrust of QD-1. CEO Richard Mansell said it has two drives a 0.25mN and a 0.65mN drive.
The DARPA funding (2018−2022 Quantized Inertia investigation) $1.3 million was for the researcher Mike McCulloch. But none of the DARPA funding has been or is yet for IVO is all privately funded. No VC or DARPA funds. The $17 Million DARPA Otter which appears intended for this type of work, but nothing has been allocated to my knowledge and definitely no DARPA funds have gone to IVO.
If they are fully successful, they will see both at once and see 3x thrust of QD-1. This would prove scaling via multiple devices. The devices are lightweight. If they have additive thrust, it will barely matter that the thrust is tiny. It means that arrays of thousands or millions of devices can be created. The devices might be one millinewton or less but then a million devices achieves constant one thousand newton thrust. The operation for a decade of multiple drives mean this would scale to full up interstellar drives. The best lab result is one watt for 52 millinewtons. The devices flown to orbit have far less thrust and each has different thrust so that it is clear whether zero, one or two devices are working.
A large number of applications in the chemical industry rely on the molecules NADH or NADPH as fuel. A team led by Professor Dirk Tischler, head of the Microbial Biotechnology working group at Ruhr University Bochum, used a biocatalyst to study their production in detail.
The researchers proved that, in addition to formate, the biocatalyst formate dehydrogenase can also convert formamides. This means, for one thing, that the enzyme can also cleave the difficult-to-break C–N bond. For another, formamides are a common solvent.
“This opens up completely new possibilities for poorly soluble NADH reactions as well as NADPH-dependent reactions,” says Tischler.
The speed of light can be intentionally reduced in various media. Various techniques have been developed over the years to slow down light, including electromagnetically induced transparency (EIT), Bose-Einstein condensate (BEC), photonic crystals, and stimulated Brillouin scattering (SBS).
Notably, researchers from Harvard, led by Lene Vestergaard Hau, reduced light speed to 17 m/s in an ultracold atomic gas using EIT, which sparked the interest in exploring EIT analogs in metasurfaces, a transformative platform in optics and photonics.
Despite the benefits, slow-light structures face a significant challenge: Loss, which limits storage time and interaction length. This issue is particularly severe for metasurface analogs of EIT due to scattering loss of nanoparticles and sometimes absorption loss of materials.
The ability of living systems to process signals and information is of vital importance. Inspired by nature, Wang and Cichos show an experimental realization of a physical reservoir computer using self-propelled active microparticles to predict chaotic time series such as the Mackey–Glass and Lorenz series.

Acoustic tweezers can control target movement through the interaction of momentum between an acoustic wave and an object. Due to their high tissue penetrability and strong acoustic radiation force, such tweezers overcome the limitations of optical and magnetic tweezers, thus making them suitable for in vivo cell manipulation.
A research team led by Prof. Zheng Hairong from the Shenzhen Institute of Advanced Technology (SIAT) of the Chinese Academy of Sciences (CAS) has recently developed a new type of acoustic tweezers —the phased-array holographic acoustic tweezers (PAHAT) system—which is based on a high-density planar array transducer capable of generating tunable three-dimensional bulk acoustic waves. The researchers hope this system can realize a pharmacological version of “telekinesis.” The study was published in Nature Communications on June 6.
The in vivo environment is extremely complex, due to the different characteristics of various tissues, organs, bones, blood vessels, and blood flow. Such a complex environment creates a huge challenge: How can acoustic methods be used to “trap” bacteria so they can produce therapeutic effects on tumors?
The latest in the intersection of large language models and life science: virus sequences, virus proteins, and their function.
Large language models improve annotation of prokaryotic viral proteins.
Ocean viral proteome annotations are expanded by a machine learning approach that is not reliant on sequence homology and can annotate sequences not homologous to those seen in training.
