images of flora from nature or of specimens, family Brassicaceae (formerly Cruciferae). Most of the native plants of this family are Saharan, if Cleomaceae is treated as a separate family as in this collection.
images of flora from nature or of specimens, family Burseraceae. Commiphora africana produces a gum (bdellium) known as albarkante in Mali and widely burned as incense.
images of flora from nature or of specimens, family Cleomaceae. This family was previously part of Capparaceae, and is now sometimes included in Brassicaceae.
images of flora from nature or of specimens, family Cucurbitaceae . There are some difficulties involving determinations of wild melons with protrusions (horns), Cucumis pustulatus/metuliferus/prophetarum. Cultivated spp. are Lagenaria (gourd, calabash), Citrullus lanatus (watermelon), and Cucurbita (squash/pumpkin).
images of flora from nature or of specimens, family Cyperaceae. Only a few of the many sedge spp. are of interest to people in central Mali: Cyperus articulatus (aromatic tubers), Cyperus esculentus (commercialized edible tubers, "pois sucrés"), Cyperus maculatus (rootstocks burned as incense), Cyperus rotundus (edible tubers, not very good and not commercialized).

Documentary videos of pottery making, notably a four-part documentary of one potter's work. Credits are at the end of videos. Additional documentaries from Mali may be added later.
images of plants, in nature or specimens, of family Euphorbiaceae. Euphorbia sudanica may include the very similar Euphorbia paganorum. Manihot is cultivated cassava. Euphorbia balsamifera is planted along roads. The two Jatropha's (of American origin) and Ricinus are planted in villages. See also Phyllanthaceae, which were moved out of Euphorbiaceae.
images of plants, in nature or specimens, of family Fabaceae (legumes), subfamily Caesalpinioideae, mimosoid clade, former Acacia spp. (sensu lato). The acacias were split in 2011 into several genera: African acacias were assigned to Faidherbia, Senegalia, and Vachellia. Acacia (sensu stricto) was delimited to Australia (due to strong-arming from the Australian timber industry), even though the type species was Acacia (now Vachellia) nilotica. Acacia ehrenbergiana was renamed Vachellia flava, in other cases the species epithet did not change when the genus changed. Many botanists continue to use Acacia for the entire complex, others recognize Faidherbia but retain Acacia for Senegalia and Vachellia. By strict botanical rules, Acacia should be limited to "Vachellia".
images of plants, in nature or specimens, of family Fabaceae (legumes), subfamily Caesalpinioideae, excluding mimosoids (e.g. acacias). The genus Cassia has been divided into Cassia (sensu stricto), Chamaecrista, and Senna.
images of plants, in nature or specimens, of family Fabaceae, subfamily Faboideae, genera T to Z. Vigna unguiculata is cultivated cowpea (the local "beans"). Vigna subterranea (ex Vouandzeia) is cultivated groundnut (resembles peanut but harder).
images of plants, in nature or specimens, of plants of the family Hernandiaceae. Genus Gyrocarpus, the only one present in the zone, is sometimes placed in its own family Gyrocarpaceae.
images of plants, in nature or specimens, of family Hydrocharitaceae. Included is genus Najas, which is sometimes elevated to family status (Najadaceae). Najas spp. are difficult for a nonspecialist to distinguish from each other and from Lagarosiphon. Ottelia is easily recognized.
images of plants, in nature or specimens, of family Lami.aceae (synonym Labiatae). Leucas and Leonotis genera overlap and may be merged. Gmelina and Vitex have been transferreed to Lamiaceae from Verbenaceae but are still listed as Verbenaceae in some websites.
images of plants, in nature or specimens, of family Lauraceae. Cassytha is a native plant. Laurus nobilis (a kind of bay leaf) is an imported dried leaf used as a spice especially in Songhay cuisine.
images of plants, in nature or specimens, of family Limeaceae. This family has recently been separated from Molluginaceae. Only Limeum pterocarpum is widespread in Central Mali.

images of plants, in nature or specimens, of family Malvaceae, genera A to G. Malvaceae (sensu lato) now includes former Bombacaceae (Adansonia, Ceiba, Bombax), Tiliaceae (Grewia, Corchorus, Triumfetta), and Sterculiaceae (Cola, Sterculia, Waltheria).
images of plants, in nature or specimens, of family Malvaceae, genus Hibiscus. H. sabdariffa (roselle) is cultivated. H. esculentus (okra) is not widely cultivated in this zone. Of native species, H. micranthus can be confused with H. pseudohirtus.
images of plants, in nature or specimens, of family Malvaceae, genera I to Z. Malvaceae (sensu lato) now includes former Bombacaceae (Adansonia, Ceiba, Bombax), Tiliaceae (Grewia, Corchorus, Triumfetta), and Sterculiaceae (Cola, Sterculia, Waltheria).
images of plants, in nature or specimens, of the family Meliaceae. Azadirachta (neem tree) is nonnative but is planted everywhere in Malian villages and cities. Khaya ("caïlcédrat") was formerly the boulevard tree of preference in cities in the colonial period; it is native to West Africa but occurs in the wild mainly farther south.
images of plants, in nature or specimens, of the family Molluginaceae. The common species in Central Mali are Mollugo nudicaulis (from which a spontaneous "soap" can be made) and Glinus lotoides. See also Aizoaceae (Trianthema, Zaleya), Gisekiaceae (Gisekia), and Limeaceae (Limeus). These families have been combined in various ways in previous classifications.
images of plants, in nature or specimens, of family Moringaceae. The local species is Moringa oleracea, planted here and there in villages chiefly for the foliage which is made into a sauce.
images of plants, in nature or specimens, of family Myrtaceae. Syzygium is the local native species and is featured here. Syzygium is rare in Central Mali but was found on the summit of Gandamiya mountain near Douentza. It is common farther south. The family also includes guava, clove, and eucalyptus.
images of plants, in nature or specimens, of family Nyctaginaceae. The genus Boerhavia has been revised since our collecting began and it is best to consider all of these images to be "Boerhavia sp.", though mostly B. coccinea.
images of plants, in nature or specimens, of family Nymphaeaceae (true water lilies, compare Menyanthaceae). Nymphaea lotus is the largest species and has distinctive dentate leaf margins. N. maculata and N. micrantha are smaller; N. maculata has roughly circular leaves, while N. micrantha has more oval-shaped leaves and usually a tuft of hairs on top of the leaf next to the stem axis.
images of plants, in nature or specimens, of family Onagraceae. The local genus is Ludwigia. L. hyssopifolia and L. erecta are the two species known in Central Mali away from the main rivers (where other spp. are also found).
images of plants, in nature or specimens, of family Orobanchaceae. The local species is Striga hermonthica, a root parasite of millet and other crop plants. The family (like Plantaginaceae) was recently separated from Scrophulariaceae, but family-level taxonomy remains controversial.
images of plants, in nature or specimens, of family Phyllanthaceae. Phyllanthus spp. and Flueggea occur wild in Central Mali. This family was formerly included in Euphorbiaceae.
images of plants, in nature or specimens, of family Plantaginaceae (sometimes called Veronicaceae). This family was recently separated from Scrophulariaceae (sensu lato), and taxonomy of these families remains unstable. Scoparia is an important medicinal plant.
images of plants, in nature or specimens, of family Portulacaceae (purslanes). Portulaca oleracea, P. quadrifida, and P. foliosa are widespread weeds, P. grandiflora is an ornamental in courtyards. Specimens deteriorate quickly. Except when flowering, P. oleracea can be confused with Trianthema portulacastrum (Aizoaceae).
images of plants, in nature or specimens, of family Rhamnaceae. The local genus is Ziziphus (jujube), of which Z. mauritiana has the most edible fruits, but is being supplanted by the introduced and planted Z. jujuba. In the wild, Z. mucronata is the other common species. Z. abyssinica was collected on the summit of Tabi mountain near Boni, Z. spina-christi occurs in deep floodplains in the Djenné area, and Z. lotus is a Saharan species.
images of plants, in nature or specimens, of family Solanaceae. Solanum nigrum and S. americanum belong to a tighly knit group whose taxonomy is unstable. Fruits of S. incanum and green fruits of S. nigrum/americanum are toxic. Datura spp. are narcotic. Capsicum spp. are chili peppers (and bell peppers). Solanum tuberosum is cultivated potato. Cultivated tomato is Solanum lycopersicum (or Lycopersicon esculentum). Cultivated tobacco is modern Nicotiana tabacum and the more traditional Nicotiana rustica.
images of plants, in nature or specimens, of family Turneraceae. Recently the family Turneraceae including Tricliceras was merged into Passifloraceae in one botanical system, but some botanists reject this. Tricliceras is a weed in villages.
images of plants, in nature or specimens, of family Verbenaceae. This family has been sharply reduced by the transfer of many genera to Lamiaceae (Vitex, Gmelina, Clerodendrum).
images of plants, in nature or specimens, of the family Zingiberaceae. In Central Mali, the relevant species are Zingiber (ginger) and melegueta pepper (Aframomum). Ginger is cultivated or imported, and melegueta pepper is imported and sold as a spice or medicine.
images of plants, in nature or specimens, of family Zygophyllaceae, including Balanites ("wild date" tree). Only Balanites and Tribulus terrestris are common in Central Mali.
images of plants, in nature or specimens, of family Bixaceae. Cochlospermum tinctorium was photographed in an ethnomedicinal garden; it has not been observed in the wild in the zone covered.
Results of computer simulation of near Earth space is looked at in a new way to understand how energy moves around the global system. It is found that in addition to a pathway of energy from the outside into the system and back again there is an internal loop which recirculates energy. These new methods will greatly improve our understanding how the whole magnetosphere system evolves and will help address evolution of processes that have space weather impacts.

Bacteria live in a broad range of environmental temperatures that require adaptations of their RNA sequences to maintain function. Riboswitches are regulatory RNAs that change conformation upon binding of typical metabolite ligands to control bacterial gene expression. The paradigmatic small class-I preQ1 riboswitches from the mesophile Bacillus subtilis (Bsu) and the thermophile Thermoanaerobacter tengcongensis (Tte) adopt similar pseudoknot structures when bound to preQ1. Here, we use single-molecule detected chemical denaturation by urea to compare the thermodynamic and kinetic folding properties of the two riboswitches, and the urea-countering effects of trimethylamine N-oxide (TMAO). This data includes the experimental findings and associated analyses detailed in the research article titled "Single-molecule FRET observes opposing effects of urea and TMAO on structurally similar meso- and thermophilic riboswitch RNAs". The data consists of multiple zip files, each representing an experiment that corresponds to the key results in the publication. Each experiment includes movies, qualifying smFRET trajectories, and analysis files related to various conditions within that experimental group.

Hurricane Ike, which struck the United States in September 2008, was the ninth most expensive hurricane in terms of damages. It caused nearly $30 billion in damage, of which nearly $12B were insured losses, after making landfall on the Bolivar Peninsula, Texas. We used the Delft3d-FM/SWAN hydrodynamic and spectral wave model to simulate the storm surge inundation around Galveston Bay during Hurricane Ike. Damage curves were established through the eight hydrodynamic parameters (water depth, flow velocity, unit discharge, flow momentum flux, significant wave height, wave energy flux, total water depth (flow depth plus wave height), and total (flow plus wave) force) simulated by the model. We found that the damage curves are sensitive to the model grid resolution, building elevation, and the number of stories.

This footage is an output of a USDOT-funded project titled "Development of Machine-Learning Models for Autonomous Vehicle Decisions on Weaving Sections of Freeway Ramps." It showcases an automated weaving maneuver within an augmented reality environment. During the demonstration, Mcity's automated vehicle navigates through a highway weaving section, making a lane change while interacting with a virtual vehicle. In this instance, Mcity's vehicle was operated by automated driving systems, which executed the lane change based on the detection for external environmental factors and parameter inputs received from the virtual vehicle.
