Exopher. Exophers are a type of membrane-bound extracellular vesicle (EV) that are released by budding out of cells into the extracellular space. Exophers can be released by neurons and muscle in the nematode Caenorhabditis elegans and also from murine cardiomyocytes. Exophers were first discovered in 2017 by an undergraduate student in the lab of Monica Driscoll at Rutgers University.

Exophers are notable for their large size, averaging approximately four microns in diameter, and they are able to expel whole organelles, such as mitochondria and lysosomes as cargo. An exopher can initially remain attached to the cell that produced it by a membranous filament that resembles a tunneling nanotube. Exophers share similarities with large oncosomes, but they differ in that they are produced by physiologically normal cells instead of aberrant cells associated with tumors.

Exopher production is thought to be a mechanism cells use to preserve homeostasis. Exophers are produced in response to numerous stressors including intracellular protein aggregation, reactive oxygen species (ROS), heat, osmotic hyertonicity, starvation, and even space flight. Mechanistically, exopher production has been found to depend on extracellular receptor signaling. Two MAPK pathways, epidermal growth factor (EGF) and fibroblast growth factor (FGF) signaling have been implicated in exopher production in nematodes. Extracellular signaling receptor MERTK, expressed by cardiac-resident macrophages, is necessary for exopher clearance by phagocytosis in mouse-derived cardiac tissue. 

Exophers may be relevant to disease. In mouse heart, eliminating macrophages or blocking their ability to engulf exophers lead to inflammation and ventricular dysregulation. Exophers may also promote pathological protein spreading in neurodegenerative diseases due to their ability to carry aggregated proteins outside of neurons, including human huntingtin protein.

O'Day 26. The O'Day 26 is an American trailerable sailboat that was designed by C. Raymond Hunt and Associates as a cruiser and first built in 1983.

Production
The design was built by O'Day Corp. in the United States between 1983 and 1985, with 85 boats completed, but it is now out of production.

Design
The O'Day 26 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a reverse transom, a transom-hung rudder controlled by a tiller and a fixed stub keel with a retractable centerboard. It displaces  and carries  of ballast.

The boat has a draft of  with the centerboard extended and  with it retracted, allowing operation in shallow water or ground transportation on a trailer.

The boat is normally fitted with a small  outboard motor or inboard for docking and maneuvering, with a maximum of  recommended. If fitted with a fixed tank, then the fuel tank holds  and the fresh water tank has a capacity of .

The design has sleeping accommodation for five people, with a double "V"-berth in the bow cabin, two straight settee berths in the main cabin and a single berth under the cockpit. The galley is located on the starboard side at the companionway ladder. The galley is L-shaped and is equipped with a two-burner stove, ice box and a sink. The head is located just aft of the bow cabin. Cabin headroom is .

The design has a PHRF racing average handicap of 234 and a hull speed of .

Operational history
In a 2010 review Steve Henkel wrote, "the O'Day 26 resembles her near-sistership, the O'Day 25 ... to an extent that makes it difficult to distinguish one from the other. Both give buyers a choice of inboard or outboard power. The cabin and cockpit layouts on both are almost identical, and feature the same 5' 6" headroom. The waterline on the '26' is eleven inches longer than on the '25' ... according to O’Day, the design basis behind the O'Day 26 was 'to maximize the idea of a boat suitable for coastwise ocean sailing and over-the-road transport by a pleasure vehicle without any special size permits.' The result, O'Day says, is a boat that 'has the right stuff for easy trailer sailing.' We wonder about that, in view of the 6,900 lbs. trailering weight, requiring a specially equipped SUV with extra engine power. A 2008 Ford E-250 van  with 4.6 liter V8 won't do it, but add a 5.4 liter engine and it will. Is that still considered a 'pleasure vehicle'? Best features: The O'Day 26 probably has a little more speed than her comp[etitor]s. Worst features: None noticed."

Zellerite. Zellerite is a uranium mineral, named after its discoverer, geologist Howard Davis Zeller. It has a type locality of the Lucky MC uranium mine in Wyoming, USA. It was approved by the IMA in 1965, but was first published a year after its approval.

Properties 
Zellerite is a dimorph of meyrowitzite. It is a uranyl carbonate. It is an acicular mineral, and occurs in crystals that resemble the shape of needles. It can occur as fine hairlike fibers as well. The size of each crystal is up to 2 mm, and it grows in roughly radial aggregates, veinlets, and incrustations. Elongation is possible.  It has pleochroic attributes, which is an optical phenomenon. Depending on which axis the specimen is being inspected, it can occur as it changes color. Upon being inspected on the x or y axis, the mineral can seem to be colorless, but on the z axis, it is seen in a pale yellow color. The mineral also shows luminescence. Under both a short wave and a long wave ultraviolet light, it fluoresces in green patches. That is due to the mineral's very strong radioactive properties, more accurately due to the high uranium concentration in it. Furthermore, measured in GRapi units, zellerite has a very strong, 3,568,854.57 radioactivity. The concentration of the mineral per Gamma Ray American Petroleum Institute Units is 280.20. As for the mineral being highly radioactive, it is due to zellerite mainly consisting of oxidized uranium, where the concentration of uranium is 45.76%, while that of oxygen is 39.98%. Otherwise, it consists of calcium (7.70%), carbon (4.62%) and hydrogen (1.94%). The fully hydrated form of the mineral is lemon yellow, but in transmitted light, it has a very pale yellow color. The dehydrated version of the mineral is called metazellerite. This rare mineral forms in the weathering zone as an oxidation product of uraninite-coffinite, in the presence of an oxidizing pyrite, where the pH is greater than 7 and the partial pressure of carbon dioxide is greater than the atmosphere's. It is associated with metazellerite, gypsum, uranophane, meta-autunite, schoepite, iron sulfides, limonite and opal.

Malimo. Malimo is a textile manufacturing technique in which warp and weft yarns are sewn together. The method is also referred to as "stitch-bonding." It was invented in Eastern Germany in the 1950s. Malimo is used in a variety of applications, including apparel fabrics, wind turbine wings and isolation fabrics, and aerospace.

Structure 
Malimo is made by layering yarn in the warp and then layering weft over it, which is then held together with an additional yarn using interlocking. Malimo variations include multineedle operation, varying the number of yarns laid, and replacing warp with fabric. For instance the heavy number of warp and weft yarns sewn with fine yarn provides woven appearance. On the other hand, using fine yarns in the warp and weft and stitching with prominent yarns creates the appearance of knitted fabric. The fabric is three-dimensional in structure and is named after the Mali or arachne from which it is made.

Heinrich Mauersberger 
Heinrich Mauersberger, a German engineer, is credited with inventing the Malimo, the series was further developed by the Chemnitz-based company Karl Mayer.
