CES Reality Check: Are Humanoid Robots Getting Better or Just Flashier?

Here is the key idea of the video in a single sentence: Humanoid robots are rapidly advancing in design, capabilities, and functionality, but despite their impressive developments, they still face significant challenges and limitations that hinder their practical application and widespread adoption.

## Questions to inspire discussion.

Manis Glove Technology.

đŸ–ïž Q: How does the Manis glove achieve accurate hand tracking? A: The glove tracks 25 degrees of freedom using inverse kinematics based on 6DOF per fingertip (position and orientation), enabling accurate motion capture even when fingertips are obscured.

🔌 Q: What hardware enables the Manis glove’s position tracking? A: The system uses transmitters at the base and receivers in fingertips to determine precise fingertip position relative to the transmitter, with simple calibration allowing different hand sizes as long as sensors stay in place.

📳 Q: How does the Manis glove provide haptic feedback? A: Haptic feedback at the PIP joints vibrates upon contact, enabling virtual world interaction and realistic surface contact simulation for teleoperation and clinical evaluations.

Abstract: This study has broad implications across multiple neurological conditions

Jian Hu & team use mouse models to show peroxisomes license myelin debris degradation in myeloid cells, which enables debris clearance and remyelination after myelin damage:

The figure shows TEM micrographs of phagocytes in which PEX5 loss (bottom panel) aggregates lipid droplets and crystal accumulation.

T cells gain superior memory through new reprogramming method, boosting cancer-fighting abilities

Georgetown University’s Lombardi Comprehensive Cancer Center researchers have identified a new way to reprogram T cells, which are infection and tumor-fighting white blood cells, so that they have a superior memory, thereby making them more effective in killing cancer cells.

The finding, published January 12, 2026, in Nature Immunology, amplifies a known strategy of blocking the cellular activity of PARP, an enzyme that detects DNA abnormalities in cells and repairs them.

“This opens the door to a new area of research in understanding how our immune system works, and as importantly, it opens the way for the development of new strategies for the treatment of cancer,” says Samir N. Khleif, MD, director of The Center for Advanced Immunotherapy Research and the director of Loop Immuno-Oncology Research Laboratory at Georgetown’s Lombardi.

Astonishing new study suggests Alzheimers can be fully reversed

The devastating illness deteriorates your brain’s ability to think, remember things and can even alter your behaviour.

While some studies have discovered that engaging in a pretty gross habit or reaching a daily step count can reduce the risk of developing Alzheimer’s disease (AD), for over a century, scientists have considered it an irreversible illness. This is why research has focused on preventing or slowing its progression, rather than recovery.

However, a new study challenges this long-held belief by testing whether brains already severely afflicted with advanced AD could recover.

There’s One Critical Thing You Can Do to Cut Your Risk of Dementia

Inside the body, a 24-hour rhythm, known as the circadian rhythm, quietly coordinates when we sleep, wake, eat, and recover. This internal timing system helps keep organs and hormones working in sync.

When it becomes disrupted, the effects may extend well beyond poor sleep, with growing evidence suggesting consequences for long-term brain health.

A large 2025 study of more than 2,000 people with an average age of 79 found that those with a strong circadian rhythm had an almost halved risk of developing dementia. Circadian rhythms regulate daily processes, including sleep timing, hormone release, heart rate, and body temperature.

DNA Gene’s Basic Structure as a Nonperturbative Circuit Quantum Electrodynamics: Is RNA Polymerase II the Quantum Bus of Transcription?

Previously, we described that Adenine, Thymine, Cytosine, and Guanine nucleobases were superconductors in a quantum superposition of phases on each side of the central hydrogen bond acting as a Josephson Junction. Genomic DNA has two strands wrapped helically around one another, but during transcription, they are separated by the RNA polymerase II to form a molecular condensate called the transcription bubble. Successive steps involve the bubble translocation along the gene body. This work aims to modulate DNA as a combination of n-nonperturbative circuits quantum electrodynamics with nine Radio-Frequency Superconducting Quantum Interference Devices (SQUIDs) inside. A bus can be coupled capacitively to a single-mode microwave resonator. The cavity mode and the bus can mediate long-range, fast interaction between neighboring and distant DNA SQUID qubits.

Robotic nanoprobe enables precise extraction of a single mitochondrion from a living cell

Mitochondrial dysfunction is associated with various chronic diseases and cancers, including neurodegenerative diseases and metabolic syndrome. Gently extracting a single mitochondrion from within a living cell—without causing damage and without the guidance of fluorescent makers—has long been a challenge akin to threading a needle in a storm for scientists.

A team led by Prof. Richard Gu Hongri, Assistant Professor in the Division of Integrative Systems and Design of the Academy of Interdisciplinary Studies at The Hong Kong University of Science and Technology (HKUST), in collaboration with experts in mechanical engineering and biomedicine, has developed an automated robotic nanoprobe.

The device can navigate within a living cell, sense metabolic whispers in real time, and pluck an individual mitochondrion for analysis or—all without the need for fluorescent labeling. It is the world’s first cell-manipulation nanoprobe that integrates both sensors and actuators at its tip, enabling a micro-robot to autonomously navigate inside live cells. The breakthrough holds great promise for advancing future treatment strategies for chronic diseases and cancer.

Novel AI method sharpens 3D X-ray vision

X-ray tomography is a powerful tool that enables scientists and engineers to peer inside of objects in 3D, including computer chips and advanced battery materials, without performing anything invasive. It’s the same basic method behind medical CT scans.

Scientists or technicians capture X-ray images as an object is rotated, and then advanced software mathematically reconstructs the object’s 3D internal structure. But imaging fine details on the nanoscale, like features on a microchip, requires a much higher spatial resolution than a typical medical CT scan—about 10,000 times higher.

The Hard X-ray Nanoprobe (HXN) beamline at the National Synchrotron Light Source II (NSLS-II), a U.S. Department of Energy (DOE) Office of Science user facility at DOE’s Brookhaven National Laboratory, is able to achieve that kind of resolution with X-rays that are more than a billion times brighter than traditional CT scans.
