A new system represents the first time that the capabilities of conventional beam-scanning lidar systems have been combined with those of a newer 3D approach known as flash lidar. The nonmechanical 3D lidar system is compact enough to fit in the palm of the hand and solves issues of detecting and tracking poorly reflective objects.

The infamous spike proteins on the surface of SARS-CoV-2 help it bind to and enter human cells. Because of their important role in spreading infection, these spike proteins are one of the main targets for COVID-19 vaccines and treatments. But those remedies gradually lose effectiveness when certain segments of the spike proteins mutate. Now, researchers report that they have discovered small molecules that successfully target other segments that mutate less.

A synthetic biosensor that mimics properties found in cell membranes and provides an electronic readout of activity could lead to a better understanding of cell biology, development of new drugs, and the creation of sensory organs on a chip capable of detecting chemicals, similar to how noses and tongues work.

Researchers developed a new approach to building deformable underwater robots, using simple repeating substructures. The team demonstrated the new system in two different example configurations, one like an eel and the other a wing-like hydrofoil.

Performing human-like motions that involve multiple contacts is challenging for robots. In this regard, a researcher has envisioned an interactive cyber-physical human (iCPH) platform with complementary humanoid (physical twin) and simulation (digital twin) elements. iCPH combines human measurement data, musculoskeletal analysis, and machine learning for data collection and augmentation. As a result, iCPH can understand, predict, and synthesize whole-body contact motions.

Researchers have used single carbon atom doping to form four chemical bonds in one step. Gamma-lactams (cyclic molecules that are common in antibiotics) were easily synthetically accessible from alpha, beta-unsaturated amides (an important molecule in cancer progression). The team chemically modified an anti-seizure medication in 96% yield, highlighting the work's utility to otherwise synthetically complex aspects of pharmaceutical development. The results of this work could become foundational to drug discovery and development.

Most cancer diagnostic techniques rely on uncomfortable and invasive procedures, such as biopsies, endoscopies or mammograms. Blood samples could be a less unpleasant option, though only a few forms of the disease can currently be diagnosed this way. But now, researchers have developed an easy-to-use method that can detect small amounts of cancer-related molecules in exosomes in plasma and effectively distinguish between malignant and benign samples.

A research group has developed a new learning method for artificial intelligence that combines classification performance for data with multiple labels with the ability to learn continually from data. Numerical experiments on real-world multi-label data indicate that the new method outperforms conventional approaches. The simplicity of this algorithm makes it easy to integrate it with other algorithms to devise new ones.
