Comb of a lifetime: a new method for fluorescence microscopy
Conventional fluorescence microscopy provides poor quantitative information of the sample because it only captures fluorescence intensity, which changes frequently and depends on external factors. Now, scientists have developed a new fluorescence microscopy technique to measure both fluorescence intensity and lifetime. Their method does not require mechanical scanning of a focal point; instead, it

Abnormal neocortex arealization and Sotos-like syndrome-associated behavior in Setd2 mutant mice
Proper formation of area identities of the cerebral cortex is crucial for cognitive functions and social behaviors of the brain. It remains largely unknown whether epigenetic mechanisms, including histone methylation, regulate cortical arealization. Here, we removed SETD2, the methyltransferase for histone 3 lysine-36 trimethylation (H3K36me3), in the developing dorsal forebrain in mice and showe

History of the solar nebula from meteorite paleomagnetism
We review recent advances in our understanding of magnetism in the solar nebula and protoplanetary disks (PPDs). We discuss the implications of theory, meteorite measurements, and astronomical observations for planetary formation and nebular evolution.

Ocean forcing drives glacier retreat in Greenland
The retreat and acceleration of Greenland glaciers since the mid-1990s have been attributed to the enhanced intrusion of warm Atlantic Waters (AW) into fjords, but this assertion has not been quantitatively tested on a Greenland-wide basis or included in models. Here, we investigate how AW influenced retreat at 226 marine-terminating glaciers using ocean modeling, remote sensing, and in situ obse

Fanconi anemia A protein participates in nucleolar homeostasis maintenance and ribosome biogenesis
Fanconi anemia (FA), the most common inherited bone marrow failure and leukemia predisposition syndrome, is generally attributed to alterations in DNA damage responses due to the loss of function of the DNA repair and replication rescue activities of the FANC pathway. Here, we report that FANCA deficiency, whose inactivation has been identified in two-thirds of FA patients, is associated with nuc

Near-infrared oxidative phosphorylation inhibitor integrates acute myeloid leukemia-targeted imaging and therapy
Acute myeloid leukemia (AML) is a deadly hematological malignancy with frequent disease relapse. The biggest challenge for AML therapy is the lack of methods to target and kill the heterogeneous leukemia cells, which lead to disease relapse. Here, we describe a near-infrared (NIR) fluorescent dye, IR-26, which preferentially accumulates in the mitochondria of AML cells, depending on the hyperacti

Synthetic lethality across normal tissues is strongly associated with cancer risk, onset, and tumor suppressor specificity
Various characteristics of cancers exhibit tissue specificity, including lifetime cancer risk, onset age, and cancer driver genes. Previously, the large variation in cancer risk across human tissues was found to strongly correlate with the number of stem cell divisions and abnormal DNA methylation levels. Here, we study the role of synthetic lethality in cancer risk. Analyzing normal tissue trans

N6-methyldeoxyadenine and histone methylation mediate transgenerational survival advantages induced by hormetic heat stress
Environmental stress can induce survival advantages that are passed down to multiple generations, representing an evolutionarily advantageous adaptation at the species level.

Full-field fluorescence lifetime dual-comb microscopy using spectral mapping and frequency multiplexing of dual-comb optical beats
Fluorescence lifetime imaging microscopy (FLIM) is a powerful tool for quantitative fluorescence imaging because fluorescence lifetime is independent of concentration of fluorescent molecules or excitation/detection efficiency and is robust to photobleaching. However, since most FLIMs are based on point-to-point measurements, mechanical scanning of a focal spot is needed for forming an image, whi

Zero-trade-off multiparameter quantum estimation via simultaneously saturating multiple Heisenberg uncertainty relations
Quantum estimation of a single parameter has been studied extensively. Practical applications, however, typically involve multiple parameters, for which the ultimate precision is much less understood. Here, by relating the precision limit directly to the Heisenberg uncertainty relation, we show that to achieve the highest precisions for multiple parameters at the same time requires the saturation

Liquid-liquid phase separation of light-inducible transcription factors increases transcription activation in mammalian cells and mice
Light-inducible gene switches represent a key strategy for the precise manipulation of cellular events in fundamental and applied research. However, the performance of widely used gene switches is limited due to low tissue penetrance and possible phototoxicity of the light stimulus. To overcome these limitations, we engineer optogenetic synthetic transcription factors to undergo liquid-liquid pha

Test sensitivity is secondary to frequency and turnaround time for COVID-19 screening
The COVID-19 pandemic has created a public health crisis.

Visual number sense in untrained deep neural networks
Number sense, the ability to estimate numerosity, is observed in naïve animals, but how this cognitive function emerges in the brain remains unclear.

We also show that the responses of these neur

Cardiolipin content controls mitochondrial coupling and energetic efficiency in muscle
Unbalanced energy partitioning participates in the rise of obesity, a major public health concern in many countries.

BBB pathophysiology-independent delivery of siRNA in traumatic brain injury
Small interfering RNA (siRNA)–based therapeutics can mitigate the long-term sequelae of traumatic brain injury (TBI) but suffer from poor permeability across the blood-brain barrier (BBB). One approach to overcoming this challenge involves treatment administration while BBB is transiently breached after injury. However, it offers a limited window for therapeutic intervention and is applicable to

Internal state configures olfactory behavior and early sensory processing in Drosophila larvae
Animals exhibit different behavioral responses to the same sensory cue depending on their internal state at a given moment. How and where in the brain are sensory inputs combined with state information to select an appropriate behavior?

Horizontal genome transfer by cell-to-cell travel of whole organelles
Recent work has revealed that both plants and animals transfer genomes between cells.

The mechanisms of genome transfer between cells are unknown. Here, we used grafting to identify the m

An unprecedented insight into the catalytic mechanism of copper nitrite reductase from atomic-resolution and damage-free structures
Copper-containing nitrite reductases (CuNiRs), encoded by nirK gene, are found in all kingdoms of life with only 5% of CuNiR denitrifiers having two or more copies of nirK . Recently, we have identified two copies of nirK genes in several α-proteobacteria of the order Rhizobiales including Bradyrhizobium sp.

Trisomy 21-induced dysregulation of microglial homeostasis in Alzheimers brains is mediated by USP25
Down syndrome (DS), caused by trisomy of chromosome 21, is the most significant risk factor for early-onset Alzheimer's disease (AD); however, underlying mechanisms linking DS and AD remain unclear. Here, we show that triplication of homologous chromosome 21 genes aggravates neuroinflammation in combined murine DS-AD models.

S100A8/S100A9 cytokine acts as a transcriptional coactivator during breast cellular transformation

Here, we show that the calcium-dependent cytokines S100A8 and S100A9 are recruited to numerous promoters and enhancers in a model of breast cellular t
