The Gemstone Cyborg: How Diamond Films Are Creating New Platforms for Cell Regeneration and Biointerfacing

Posted by in categories: biotech/medical, cyborgs, neuroscience

Diamond is a promising material for the biomedical field, mainly due to its set of characteristics such as biocompatibility, strength, and electrical conductivity. Diamond can be synthesised in the laboratory by different methods, is available in the form of plates or films deposited on foreign substrates, and its morphology varies from microcrystalline diamond to ultrananocrystalline diamond. In this review, we summarise some of the most relevant studies regarding the adhesion of cells onto diamond surfaces, the consequent cell growth, and, in some very interesting cases, the differentiation of cells into neurons and oligodendrocytes. We discuss how different morphologies can affect cell adhesion and how surface termination can influence the surface hydrophilicity and consequent attachment of adherent proteins.

Two Revolutionary AI Chips Can Control Robots Through Thought

Posted by in categories: innovation, robotics/AI

These two chips might be the key to developing sophisticated brain-computer interfacing.

Scientists from the University of Electronic Science and Technology of China claim to have developed the world’s most energy-efficient artificial intelligence AI microchips that are small enough to fit inside smart devices and could open doors for innovative offline functions like voice and even mind control.

Generally, AI chips that are designed for heavy tasks often require significant power because of high computational demands, which limits their use in real-world scenarios. Professor Zhou Jun and his team managed to significantly reduce power consumption through algorithm and architectural optimization.

Researchers find first experimental evidence for a graviton-like particle in a quantum material

Posted by in categories: particle physics, quantum physics

A team of scientists from Columbia, Nanjing University, Princeton, and the University of Munster, writing in the journal Nature, have presented the first experimental evidence of collective excitations with spin called chiral graviton modes (CGMs) in a semiconducting material.

Robot, can you say ‘Cheese’?

Posted by in category: robotics/AI

Columbia engineers build Emo, a silicon-clad robotic face that makes eye contact and uses two AI models to anticipate and replicate a person’s smile before the person actually smiles — a major advance in robots predicting human facial expressions accurately, improving interactions, and building trust between humans and robots.

Groundbreaking study shows how lifestyle changes can reverse biological aging

Posted by in categories: biological, genetics, life extension

In a groundbreaking study led by Dr. Karen Fitzgerald, six women between the ages of 45 and 65 experienced a remarkable reduction in their biological age by an average of five years in just eight weeks. The findings offer promising insights into the potential of lifestyle changes to combat aging.

The study, which focused on the distinction between chronological age and biological age, revealed that while chronological age remains fixed, biological age — the age of one’s cells — can be influenced and even reversed through targeted interventions.

Using Dr. Steven Horvath’s epigenetic clock, which measures 353 markers associated with methylation changes linked to aging, the researchers assessed the participants’ biological age before and after the intervention.

‘Exhausted’ immune cells in healthy women could be target for breast cancer prevention

Posted by in categories: biotech/medical, genetics

Everyone has BRCA1 and BRCA2 genes, but mutations in these genes—which can be inherited—increase the risk of breast and .

The study found that the in breast tissue of healthy women carrying BRCA1 or BRCA2 gene mutations show signs of malfunction known as exhaustion. This suggests that the immune cells can’t clear out damaged breast cells, which can eventually develop into breast cancer.

This is the first time that exhausted immune cells have been reported in non-cancerous breast tissues at such scale—normally these cells are only found in late-stage tumors. The results raise the possibility of using existing immunotherapy drugs as early intervention to prevent breast cancer developing, in carriers of BRCA1 and BRCA2 gene mutations.

Tesla Supercharger NACS access clarified by TSLA Exec

Posted by in categories: business, policy, sustainability, transportation

Tesla executive Rohan Patel clarified some facts about Supercharger NACS access for non-Tesla vehicles like Rivian and Ford.

Patel—Tesla’s Vice President of Public Policy and Business Development—recently replied to a question from Teslavangelist, who questioned the number of Supercharger stalls non-Tesla owners actually had access to with NACS connectors.

Tesla recently opened the Supercharger Network to Ford and Rivian electric vehicles (EVs) through its NACS connecter. Both automakers claim that NACS connectors provide Ford and Rivian owners access to over 15,000 Tesla Supercharger locations. Teslavangelist pointed out that non-Tesla EV owners only have access to V3 and V4 Superchargers, doubting they have access to 15,000 Supercharger stalls.
