The practice reaches back to when cheesemakers in England skimmed the butterfat from milk to make butter, according to Elizabeth Chubbuck of Murray’s Cheese in New York. The leftover milk was whiter, so cheesemakers added pigments to recreate butterfat’s golden hue, she said.

Although such thermosalient behavior—also known as the jumping crystal effect—has been observed in other types of crystals, it had not been observed in this particular class of organic semiconducting crystals, Gassensmith said. Such behavior is of interest to researchers because it might be exploited for applications such as micromachines, sensors, or tiny actuators for medical devices and artificial muscles.

Judges were impressed by the striking design of "The Family Bach", which features three different buildings that surround a recessed patio and timber deck that creates a "campsite".

Here, a ternary heterostructure (Fig. 1), magnetic Fe3O4@GO@TiO2 (denoted as MGT), was developed (10), working as a plasmon-free SERS substrate with high molecular selectivity and stability, as well as a remarkable EF value of up to 8.08 × 106. This notable EF value was found to be mainly attributed to a high-efficiency interfacial CT process between GO and TiO2, which was verified by theoretical calculation and time-resolved diffuse reflectance (TDR) spectroscopic measurements. The present SERS substrate with high sensitivity and selectivity was developed to determine trace biological species, such as programmed cell death receptor ligand 1 (PD-L1, a model molecule), at the single-cell level. PD-L1 and its predominant target, programmed death 1 (PD-1), are two crucial immune checkpoint molecules tightly associated with immune resistance (11), which promote immune evasion and tumor recurrence and metastasis (12). PD-L1 is rarely expressed in regular epithelial tissues but is aberrantly expressed in many cancers, including breast (13), melanoma (14), and renal cell carcinoma (15). Immunotherapy using anti–PD-1 or anti–PD-L1 antibody (Ab) to block the interaction between PD-1 and PD-L1 has shown positive antitumor effects in clinical studies (16). Therefore, the quantitative characterization of PD-L1 expression on the cell surface has become an extremely important subject directly related to the development of diagnostic tools to guide PD-L1–based personalized treatment. A variety of analytical tools for PD-L1 monitoring have been reported during the past few years, such as immunohistochemical detection, mass spectrometry (MS), radiological imaging, flow cytometry, and positron emission tomography (17–21). To give a better understanding of the structural and functional roles that cells play in biological systems, it is necessary to develop a robust tool for the analysis and quantification of the components and metabolites in different individual cells (22). Developing a robust preliminary testing approach that provides reliable and quantitative diagnostic results in real time and in situ PD-L1 monitoring at the single-cell level remains a challenge. Triple-negative breast cancer cells (TNBCs) are types of cancer cells that always exhibit immune evasion and tumor recurrence and metastasis triggered by PD-L1 (12). In this experiment, we successfully used an MGT-based SERS probe to visualize and compare the expression and distribution of PD-L1 on three different kinds of TNBC surfaces at the single-cell level, which helped us to understand how PD-L1 behaves within different breast cancer genomic subtypes.

The colors in this palette are amazing. A mix of cool and warm colors, matte, luster and sateen finishes…it’s a perfect palette for the season. I love the rich, purple tones and with 12 colors, you have endless combinations of looks to create.

One of the biggest differences between the Echo and the Echo Plus is the in-built Zigbee smart home hub. While the Echo can communicate with other Echo devices, the Zigbee hub can communicate with non-Echo smart devices such as Philips Hue smart bulbs, smart plugs and smart switches.

You may not think of your red wine as a dye, but it’s full of anthocyanins, which are common natural dyes for textiles. Even worse, when you find them in wine, they’re dissolved in alcohol and water, making your glass’s contents the perfect cocktail to ruin any cloth they touch.

Some recent academic and popular literature implies that the problem of the colonization of the Americas has been largely resolved in favor of one specific model: a Pacific coastal migration, dependent on high marine productivity, from the Bering Strait to South America, thousands of years before Clovis, the earliest widespread cultural manifestation south of the glacial ice. Speculations on maritime adaptations and typological links (stemmed points) across thousands of kilometers have also been advanced. A review of the current genetic, archeological, and paleoecological evidence indicates that ancestral Native American population expansion occurred after 16,000 years ago, consistent with the archeological record, particularly with the earliest securely dated sites after ~15,000 years ago. These data are largely consistent with either an inland (ice-free corridor) or Pacific coastal routes (or both), but neither can be rejected at present. Systematic archeological and paleoecological investigations, informed by geomorphology, are required to test each hypothesis.
