Sperm motility and anchoring of the spore capsule in spreading earthmoss
As a component of moors, mosses are important for climate conservation. They are also gaining increasing significance in biotechnology and the manufacture of biopharmaceuticals. For the most varied of reasons, mosses are interesting research objects......»»
This portable projector is about the size of can of La Croix, and it’s $60 off
The Anker Nebula Capsule portable projector is just as big as a cola can, but it can project images of up to 100 inches. It's on sale from Amazon for only $240......»»
Researchers find having good neighbors and few top predators make predatory fish populations more resilient
A regime shift is gradually spreading through the archipelagos of the Swedish Baltic Sea coast, where shallow bays, previously dominated by pike and perch have one by one become dominated by one of their prey species, the three-spined stickleback......»»
Researchers present near-complete genome version of spreading earth moss
The model organism spreading earth moss (Physcomitrium patens, formerly: Physcomitrella patens) has contributed significantly to a better understanding of plant evolution and development. Nevertheless, the currently known genome of Physcomitrium pate.....»»
A new generation of spaceplanes is taking advantage of the latest in technology
NASA's space shuttle operated in low-Earth orbit for 30 years before its retirement in 2011. However, the US space agency's replacement for this vehicle, Orion, returned to the conical capsule design familiar from the Apollo missions. This was becau.....»»
Enrichment of anchoring sites via supramolecular halogen bonds for efficient perovskite nanocrystal LEDs
Colloidal semiconductor nanoparticles can be viewed as a complex of an inorganic single crystal core and a monolayer of organic ligands. The location and type of ligand anchoring on the nanocrystal surface are critical to the nanocrystal morphology,.....»»
Scientists successfully simulate protein complex that initiates fertilization
Researchers at ETH Zurich recently developed highly realistic simulations of the proteins on sperm and egg cells coupling together before they fuse. These findings enabled the research team to solve several mysteries of fertilization at once, which c.....»»
Scientists identify potential new method for diagnosing male infertility
Researchers have discovered a new phenomenon where sperm from mice can induce non-reproductive cells from hamsters to fuse and form a syncytia—a cell with multiple nuclei......»»
Indonesia"s Mount Merapi unleashes lava as other volcanoes flare up, forcing thousands to evacuate
Indonesia's Mount Merapi erupted Sunday, spreading searing gas clouds and avalanches of lava down its slopes as other active volcanoes flared up across the country, forcing the evacuation of thousands......»»
Missing gene in mouse sperm could explain infertility
Mice lacking a certain gene are unable to produce offspring because their sperm lack the connection between the tail and the head. A new thesis from the University of Gothenburg indicates a probable cause of male infertility......»»
A Gel Injected Into the Scrotum Could Be the Next Male Contraceptive
Biotech company Contraline has safely implanted a sperm-blocking hydrogel in 23 men. It’s designed to be a fully reversible vasectomy......»»
Sperm whales found to live in large, matrilineally based clans
A sperm whale expert at Dalhousie University, in Canada, has found evidence showing that sperm whales form large matrilineally based clans that have their own coda dialect. In his paper published in the journal Royal Society Open Science, Hal Whitehe.....»»
Juvenile sperm whale euthanized after stranding on North Carolina beach
A juvenile sperm whale that appeared to be in poor health was euthanized Wednesday after stranding on a North Carolina beach......»»
New technology for long-term liquid storage of chicken semen by arresting energy metabolism
Researchers from the University of Tsukuba have developed an advanced refrigerated storage technology that prolongs the fertilization capacity of chicken sperm by arresting the energy metabolism dynamics, achieved through the depletion of calcium ins.....»»
Eggs from men, sperm from women: How stem cell science may change how we reproduce
It may soon be possible to coax human skin cells into becoming functional eggs and sperm using a technique known as "in vitro gametogenesis." This involves the creation (genesis) of eggs and sperm (gametes) outside the human body (in vitro)......»»
Drug-resistant fungus is on the rise worldwide, says molecular biologist
The Candida auris fungus is spreading across the globe at an "alarming" speed. This species of fungus, which can cause fatal infections in risk groups and was first discovered only 10 years ago, can now be found all over the world. In nearly all case.....»»
Eelgrass proves to be evolutionarily much younger than we thought
Eelgrass, one of the most abundant plants in the ocean, originated in Japan before spreading around the globe. Now, scientists have shed light on both when and how eelgrass adapted and evolved throughout its history......»»
After 15 months Blue Origin’s New Shepard spacecraft will finally fly again
Taking some science and some postcards for a ride. Enlarge / Blue Origin's New Shepard launch system consists of a booster and a capsule. (credit: Blue Origin) Blue Origin is finally returning to flight. On Tuesday the.....»»
Rocket Report: The final space shuttle stack; SpaceX may extend booster lifetimes
"God willing, the suborbital tests of the new generation 'bio-capsule' will be completely Iranian." Enlarge / Solid rocket motors are stacked at the California Science Center for an eventual vertical display of space shuttle Ende.....»»
Crossed wires led to high drama as NASA returned asteroid samples to Earth
