Stem carbohydrate richness in two cycad species
Terrestrial plants have developed strategies to cope with suboptimal conditions. Storage of nonstructural resources is one of those strategies. Nonstructural carbohydrates (NSCs) of plants are primarily sugars and starch, and have been studied extens.....»»
By exerting "crowd control" over mouse cells, scientists make progress towards engineering tissues
Genes aren't the sole driver instructing cells to build multicellular structures, tissues, and organs. In a paper published in Nature Communications, USC Stem Cell scientist Leonardo Morsut and Caltech computational biologist Matt Thomson characteriz.....»»
With new imaging approach, scientists closely analyze microbial adhesive interactions
Scientists have identified many types of bacteria in the mouth, but many problems remain in understanding how they work with one another. One of the problems is that microbes assemble themselves into densely packed multi-species biofilms. Their densi.....»»
Expert explains effects of catastrophic weather events on forests and tree species
This year has seen its share of severe weather—but how do these powerful storms impact forests over the long term? A Virginia Tech forest health expert breaks down the long-term effects catastrophic weather events can have and how to revive hard-hi.....»»
Tiny worm makes for big evolutionary discovery: Scientists describe "Uncus," the oldest ecdysozoan
Everyone has a past. That includes the millions of species of insects, arachnids, and nematode worms that make up a major animal group called the Ecdysozoa......»»
Viscosity of materials key to cell differentiation: New insights could improve design of biomaterials
An IBEC-led study has revealed how mesenchymal stem cells respond to the viscosity of their environment, a key aspect in their differentiation process......»»
Mathematical model can help understand coexistence in nature
Different species of seabirds can coexist on small, isolated islands despite eating the same kind of fish. A researcher at Uppsala University has been involved in developing a mathematical model that can be used to better understand how this ecosyste.....»»
How marine worms regenerate lost body parts: Return of cells to stem cell-like state could be key
Many living organisms are able to regenerate damaged or lost tissue, but why some are particularly good at this and others are not is not fully understood. Molecular biologists Alexander Stockinger, Leonie Adelmann and Florian Raible from the Max Per.....»»
Worm species thought to have disappeared has been appearing in photos of pygmy seahorses all along
A small team of marine scientists from the University of the Ryukyus, King Abdullah University of Science and Technology and the Kuroshio Biological Research Foundation, has found that a worm species thought to be missing since 1957 has been appearin.....»»
California researchers discover mysterious, gelatinous new sea slug
More than two decades after spotting a mysterious, gelatinous, bioluminescent creature swimming in the deep sea, California researchers this week announced that it is a new species of sea slug......»»
Genes of ancient animal relatives used to grow a mouse: Study reveals hidden history of stem cells
An international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular organism, with which we share a common ancestor that p.....»»
Cross-species transplantation: Generation of rat offspring from ovarian oocytes in mice
The idea of maturing oocytes in the ovary to produce offspring has been implemented in various ways. One such method, ovarian transplantation, is a relatively simple procedure for obtaining eggs, compared to in vitro culture of ovaries and follicles......»»
Troubled waters: How to stop Australia"s freshwater fish species from going extinct
Three-quarters of Australia's freshwater fish species are found nowhere else on the planet. This makes us the sole custodians of remarkable creatures such as the ornate rainbowfish, the ancient Australian lungfish and the magnificently named longnose.....»»
One year after the end of Apple leather iPhone cases, what do you use? [Poll]
I’m fairly firmly convinced that people who don’t keep their iPhone in a case are from an entirely different species to me. While I don’t make a habit of dropping mine, I don’t think there has been a year in which I haven’t dropped or knock.....»»
Q&A: Holobiont biology, a new concept for exploring how microbiome shapes evolution of visible life
Microorganisms—bacteria, viruses and other tiny life forms—may drive biological variation in visible life as much, if not more, than genetic mutations, creating new lineages and even new species of animals and plants, according to Seth Bordenstei.....»»
Bone Marrow Donors Can Be Hard to Find. One Company Is Turning to Cadavers
San Francisco–based Ossium Health has carried out three transplants for cancer patients using stem cells from deceased donors’ bone marrow in recent months......»»
Ocean warming and acidification threaten key ocean plankton groups, study warns
According to a recent study published in Nature, many planktonic foraminifera species may face unprecedented environmental conditions by the end of this century, potentially surpassing their survival thresholds. Planktonic foraminifera are single-cel.....»»
Researchers identify two primary tree movement patterns that help them survive high winds and prevent damage
Destructive winds during storms and cyclones often cause tree failures, especially through uprooting and stem breakage. However, how trees respond to wind under various forest configurations and weather conditions remains unclear......»»
Bioengineered yeast mass produces herbal medicine
Herbal medicine is difficult to produce on an industrial scale. A team of Kobe University bioengineers manipulated the cellular machinery in a species of yeast so that one such molecule can now be produced in a fermenter at unprecedented concentratio.....»»
Endangered creature hit and killed by vehicle in Florida—the 27th death this year
A 2-year-old panther—listed as an endangered species—was found dead on a road in Florida, marking the 27th panther death in the state this year, records show......»»
Biologists discover new species of gecko
A team of biologists led by The University of Texas at Arlington has discovered a new tiny lizard species in the Paria Peninsula of northeastern Venezuela. This discovery, accepted for publication in the Zoological Journal of the Linnean Society, hig.....»»
