The Mystery of Consciousness: Antonio Damasio & David Chalmers with Marcelo Gleiser

A neuroscientist, a philosopher and a physicist convene to discuss one of the biggest and most significant questions of all time: human consciousness, what we know and don’t know about it, and whether science will ever be able to understand what makes you, you.

Recorded Oct 16, 2016 at The 92nd Street Y, New York.

CATL unveils battery with 12-minute charging and 1.5 million mile life

The company is already the world’s largest battery maker, supplying cells to major automakers. With this latest development, the battery giant is positioning itself at the center of the race to deliver gasoline-like convenience without sacrificing durability.

The core challenge engineers set out to address was whether an EV battery could withstand repeated ultra-fast charging without rapid degradation. A 5C charge rate means an 80-kilowatt-hour battery pack could theoretically accept around 400 kilowatts of power. That level of charging can refill a battery in roughly 12 minutes, similar to a typical gas stop.

Fast charging has long been associated with faster wear. The engineers tested whether the chemistry could handle that stress over time. According to the company, the answer was yes. Under standard conditions at 68°F, the battery retained at least 80 percent of its original capacity after 3,000 full charge-and-discharge cycles.

Realization of two-dimensional discrete time crystals with anisotropic Heisenberg coupling

Experimental realizations of discrete time crystals have mainly involved 1D models with Ising-like couplings. Here, the authors realize a 2D discrete time crystal with anisotropic Heisenberg coupling on a quantum simulator based on superconducting qubits, uncovering a rich phase diagram.

Community Series in Vaccines and approaches that target trained immunity in COVID-19: Immunological mechanisms of action and delivery: Volume II

2024 This is a first of its kind univversal covid 19 vaccine that would allow for a one time shot that is good for current versions of the virus and future versions aswell.

A universal recombinant adenovirus type-5 (Ad5) vaccine against COVID19 (Ad-US) was constructed, and immunogenicity and broad-spectrum of Ad5-US were evaluated with both intranasal and intramuscular immunization routes. The humoral immune response of Ad5-US in serum and bronchoalveolar lavage fluid were evaluated by the enzyme-linked immunosorbent assay (ELISA), recombinant vesicular stomatitis virus based pseudovirus neutralization assay, and angiotensin-converting enzyme-2 (ACE2)-binding inhibition assay. The cellular immune response and Th1/Th2 biased immune response of Ad5-US were evaluated by the IFN-γ ELISpot assay, intracellular cytokine staining, and Meso Scale Discovery (MSD) profiling of Th1/Th2 cytokines. Intramuscular priming followed by an intranasal booster with Ad5-US elicited the broad-spectrum and high levels of IgG, IgA, pseudovirus neutralizing antibody (PNAb), and Th1-skewing of the T-cell response. Overall, the adenovirus type-5 vectored universal SARS-CoV-2 vaccine Ad5-US was successfully constructed, and Ad5-US was highly immunogenic and broad spectrum. Intramuscular priming followed by an intranasal booster with Ad5-US induced the high and broad spectrum systemic immune responses and local mucosal immune responses.

According to the World Health Organization, as of March 15, 2024, over 774 million COVID-19 cases and almost 7 million related deaths had been reported globally. A total of 13.59 billion doses of COVID-19 vaccines have been reportedly administered globally, leading to a vaccination rate of 69.7%. At present, at least 24 types of COVID-19 vaccines have been authorized for emergency use in various countries. According to the list of global COVID-19 candidate vaccines published on the WHO website, a total of 183 candidate vaccines are in clinical development and 199 candidate vaccines are in the preclinical evaluation stage as of April 8, 2023. Recombinant protein subunit vaccines account for the greatest proportion of vaccines in clinical development (59 vaccines, 32%), followed by RNA vaccines (43 vaccines, 24%).

The fetal trophoblast cell marker HLA-G activates a type I interferon response in primary NK cells through the receptor KIR2DL4

Scientists have discovered how cells from the fetus could activate maternal natural killer cells during early pregnancy, helping to demystify the poorly understood mechanisms that govern immune cells at the maternal-fetal interface.

A fetal cell antigen interacts with a natural killer cell receptor to induce antiviral gene expression.

D–d/p Orbital Hybridization in Symmetry-Broken Co–Y Diatomic Sites Enables Efficient Na–S Battery

JUST PUBLISHED: JUST PUBLISHED: d–d/p Orbital Hybridization in Symmetry-Broken Co–Y Diatomic Sites Enables Efficient Na–S Battery.

Read the latest free, Open Access article from Energy Material Advances.

Despite advances of single-atom catalysts (SACs) in sodium–sulfur (Na–S) batteries, their symmetric coordination geometry (e.g., M–N4) fundamentally restricts orbital-level modulation of sulfur redox kinetics. Herein, we demonstrate that hetero-diatomic Co–Y sites with Co–N4–Y–N4 coordination on N-doped carbon (Co–Y/NC) break the M–N4 symmetry constraint through d–d orbital hybridization, which is confirmed by an implementation of advanced characterizations, including the high-angle annular dark-field scanning transmission electron microscopy and x-ray absorption fine structure spectroscopy. In practical operation, the Co–Y/NC@S cathode with 61% sulfur mass fraction delivers a superior capacity (1,109 mAh/g) at 0.2 A/g, outperforming that of Co or Y SAC and further setting a new benchmark of diatomic catalysts for Na–S battery systems.

Exploring the role of apolipoprotein ε4 in progressive myoclonic epilepsy type 1

“Despite greater white matter degeneration and reduced cortical thickness, APOE ε4 carriers exhibited preserved deep brain volumes and better self-reported well-being. This study highlights the complex interplay between genetic factors and neurodegenerative processes. Our future research aims to provide more natural history data of EPM1 and correlate long-term phenotypic data with additional geno-phenotypic analyses.”

Read this original article from Epileptic Disorders at doi.org/10.1002/epd2.70112.

Objective Progressive myoclonic epilepsy type 1 (EPM1) is a neurodegenerative disease caused by biallelic variants in the cystatin B (CSTB) gene. Despite a progressive course, phenotype severity varies among patients, even within families. We studied the potential role of APOE ε4 in modifying phenotypic diversity in EPM1, given its established association with neurodegeneration, particularly in Alzheimer’s disease.
