The analysis of ancient DNA preserved in sediments is an emerging technology allowing for the detection of the past presence of humans and other animals at archaeological sites. Yet, little is known about how DNA is preserved in sediment for long periods of time. Scientists have now shed light on the matter by isolating DNA from solid blocks of undisturbed sediment that are embedded in plastic resin. The study reveals that ancient human and animal DNA is concentrated in small 'hot spots', particularly in microscopic particles of bone or feces. Micro-sampling of such particles can recover substantial amounts of DNA from ancient humans, such as Neanderthals, and other species and link them to archaeological and ecological records at a microscopic scale. from Latest Science News -- ScienceDaily https://ift.tt/3JqnkSF

Just like every other organism on Earth, plants' ultimate goal is to survive and reproduce. In order to achieve this, they must make trade-offs between where and how to allocate their finite set of resources.

The pioneers of holography (Gabor, Leith, Upatnieks, and Denisyuk) predicted very early that the ultimate 3D display will be based on this technique. This conviction was rooted in the fact that holography is the only approach that can render all optical cues interpreted by the human visual system. Holographic 3D displays have been a dream chased after for many years, facing challenges on all fronts: Computation, transmission, and rendering. With numbers such as 6.6 × 1015 flops required for calculations, 3 × 1015 b/s data rates, and 1.6 × 1012 phase pixels, the task has been daunting. from Phys.org - latest science and technology news stories https://ift.tt/3sDVcFG

Blood flow velocity is an important parameter reflecting vascular function.

The ability to quantify optical properties (i.e., absorption and scattering) of strongly turbid media has major impacts on the characterization of biological tissues, fluid fields, and many others. However, the task of quantitative imaging of optical properties for strongly turbid media is intrinsically challenging, as photon scattering hinders direct measurement over length scales larger than the mean free path. Few current imaging technologies can quantify absorption and scattering properties of strongly turbid media in a wide-field non-contact format, and none have been shown to map quantitative optical properties with high-speed (e.g., kHz) capabilities. from Phys.org - latest science and technology news stories https://ift.tt/3sSpg0r

Developing low-cost and highly efficient electrocatalysts for oxygen reduction reaction (ORR) to replace commercial Pt/C has always been desired to greatly reduce the cost of polymer electrolyte membrane (PEM) fuel cells. The parameter of half-wave potential (E1/2) obtained from linear-sweep voltammetry (LSV) in O2-saturated acid/alkaline medium on a rotating disk electrode (RDE) is commonly used for characterizing the ORR performance of all kinds of new electrocatalysts. With higher value of E1/2, the ORR performance becomes better. For comparison, the E1/2 value of Pt/C is extensively used as a benchmark. from Phys.org - latest science and technology news stories https://ift.tt/3Eyr5Sn

By analyzing the acquisition-conservation tradeoff in root systems among different plants, ecologists have put forward the root economics spectrum (RES) hypothesis. Some plant species have finer and cost-effective absorptive roots that contribute to rapid nutrient uptake but have shorter lifespans, whereas others have thicker and less cost-effective absorptive roots marked by slower nutrient acquisition but longer lifespans. The RES hypothesis reflects the correlations among different root traits, which can facilitate the adaptation of plants to the local environment. The RES is one of the core issues in root ecology, but its adaptive role and genetic basis remains largely elusive. from Phys.org - latest science and technology news stories https://ift.tt/3Hh49Zm

Studies of the genomic DNA compaction in the cell nucleus and dynamic reorganization during physiologic processes or disease development in live cell environments are exceedingly challenging. This complexity stems from a high degree of compaction required to accommodate ~2 meters of genomic DNA within the cell nucleus, which typically is 5 to 10 micrometers in diameter. In addition, the chromatin compaction density is not static, but fluctuates over time accommodating for gene activities. Meanwhile, the 3D resolution of optical microscopy is not high enough even for sub-diffraction imaging modalities, thus limiting studies of the spatial geometry of complex genomic architecture and its dynamic transformations. from Phys.org - latest science and technology news stories https://ift.tt/3z4w63C

With the demand in real-time monitoring of endoplasmic variations and rapid detection of extracellular signals, a great number of approaches to bioimaging have been developed. The past few decades have witnessed a dramatic progress in optical imaging, especially with the emerging of microsphere-assisted techniques that have the excellent ability of signal collection and enable real-time and super-resolution imaging with conventional optical microscopic systems. However, as most of the microspheres in current strategies are in solid and artificially synthetic materials, they are of very low biocompatibility. Fortunately, lessons from nature have shown that some bio-components and already-existing objects can interact with light and are able to take the same functions as the real optical elements. from Phys.org - latest science and technology news stories https://ift.tt/3qsQ6sZ

Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concepts of metasurface and metamaterials have proven fruitful results in the realm of meta-optics.

However, recent research is revealing the prominent potential of leveraging subwavelength meta-structured waveguides to enable exotic waveguiding phenomena and design novel waveguide-based devices. from Phys.org - latest science and technology news stories https://ift.tt/3FNyTkF

Optical interference is not only a fundamental phenomenon that has enabled new theories of light to be derived, but it has also been used in interferometry for the measurement of small displacements, refractive index changes, and surface irregularities. The Michelson interferometer is a commonly used interferometer, by which the equal-inclination and equal-thickness interference fringes of light can be easily observed. Historically, this interferometer has been used in many famous physical experiments, such as the Michelson-Morey experiment and gravitational wave detection. from Phys.org - latest science and technology news stories https://ift.tt/3HgJZPf

Cylindrical vector beam (CVB) multiplexing has emerged as a powerful technique to boost signal channels. Coupling and separating CVBs are two pivotal elements in CVB multiplexing communication. Although off-axis control technologies such as miniature Dammann vortex gratings have been investigated to couple and separate light beams, it is usually limited to light beams with homogeneous polarization due to its phase-only grating structure. For CVBs with inhomogeneous polarization, a gradient phase device is required to create a gradient phase difference between the left- and right-handed circularly polarized (LHCP/RHCP) components, so that the CVBs with off-axis incident angles can coaxially propagate and carry different phase structures. Despite considerable efforts of off-axis control technologies, the off-axis polarization control of CVBs still remains a challenge. from Phys.org - latest science and technology news stories https://ift.tt/3FBBGgG

Some microbes can form thin films called biofilms. These biofilms give them an advantage over other microbes by protecting them from stresses such as a lack of nutrients or the presence of harmful substances in the environment. Researchers often focus on the biofilms that pathogens use to resist antibiotics. However, some biofilms can be helpful to plants and other host organisms. In previous work, researchers found that Pantoea sp. YR343, a bacterium that promotes plant growth, forms robust biofilms along the root surface of Populus, the genus which includes willow and cottonwood trees. Scientists know relatively little about the mechanisms behind the formation of biofilms on plant roots, particularly at the genetic level. However, research has found that enzymes called diguanylate cyclases are key to biofilm formation. This new research has identified a diguanylate cyclase, DGC2884, that is expressed specifically in the presence of plants when bacteria colonize roots and form biofilm...
