Published Fast electrical signals mapped in plants with new bioelectronic technology



What happens inside the carnivorous plant Venus Flytrap when it catches an insect? New technology has led to discoveries about the electrical signalling that causes the trap to snap shut. Bioelectronic technology enables advanced research into how plants react to their surroundings, and to stress.
Published Lifespan of aging science's model organism driven by reproductive self-destruction



The lifespan of a small roundworm that has been used as a key model organism in aging research is limited by how it self-sacrifices to feed its young, finds a new study.
Published New findings offer potential breakthrough in HIV cure research



The results of a novel study has revealed exciting findings in the pursuit of an HIV cure.
Published Discovery of key genetic sequence essential for plant reproduction



Researchers have identified a genetic sequence that is essential for plant reproduction. As this region is found in all plant species, it is expected to contribute to future crossbreeding initiatives and help solve the important problem of seed formation defects.
Published Greenland melted recently: High risk of sea level rise today



A large portion of Greenland was an ice-free tundra landscape -- perhaps covered by trees and roaming woolly mammoths -- in the recent geologic past (about 416,000 years ago), a new study shows. The results help overturn a previous view that much of the Greenland ice sheet persisted for most of the last two and a half million years. Instead, moderate warming, from 424,000 to 374,000 years ago, led to dramatic melting. At that time, the melting of Greenland caused at least five feet of sea level rise, despite atmospheric levels of heat-trapping carbon dioxide being far lower than today (280 vs. 420 ppm). This indicates that the ice sheet on Greenland may be more sensitive to human-caused climate change than previously understood -- and will be vulnerable to irreversible, rapid melting in coming centuries.
Published Crawford Lake, Canada, chosen as the primary marker to identify the start of the Anthropocene epoch



An international team of researchers has chosen the location which best represents the beginnings of what could be a new geological epoch, the Anthropocene. The Anthropocene Working Group have put forward Crawford Lake, in Canada, as a Global Boundary Stratotype Section and Point (GSSP) for the Anthropocene. A GSSP is an internationally agreed-upon reference point to show the start of a new geological period or epoch in layers of rock that have built up through the ages.
Published Global cooling caused diversity of species in orchids, confirms study



Research shows global cooling of the climate 10 million years ago led to an explosion of diversity in terrestrial orchids.
Published Why there are no kangaroos in Bali (and no tigers in Australia)



Researchers are using a new model to clarify why millions of years ago more animal species from Asia made the leap to the Australian continent than vice versa. The climate in which the species evolved played an important role.
Published Shrinking Arctic glaciers are unearthing a new source of methane



As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new research.
Published New study reveals abrupt shift in tropical Pacific climate during Little Ice Age



An El Niño event has officially begun. The climate phenomenon, which originates in the tropical Pacific and occurs in intervals of a few years will shape weather across the planet for the next year or more and give rise to various climatic extremes. El Niño-like conditions can also occur on longer time scales of decades or centuries. This has been shown to have occurred in the recent past.
Published Research reveals sources of CO2 from Aleutian-Alaska Arc volcanoes



Scientists have wondered what happens to the organic and inorganic carbon that Earth's Pacific Plate carries with it as it slides into the planet's interior along the volcano-studded Ring of Fire. A new study suggests a notable amount of such subducted carbon returns to the atmosphere rather than traveling deep into Earth's mantle.
Published Climate change will increase impacts of volcanic eruptions



Volcanic disasters have been studied since Pompeii was buried in 79 A.D., leading the public to believe that scientists already know why, where, when and how long volcanoes will erupt. But a volcanologist said these fundamental questions remain a mystery.
Published There may be good news about the oceans in a globally warmed world



An analysis of oxygen levels in Earth's oceans may provide some rare, good news about the health of the seas in a future, globally warmed world. A study analyzing ocean sediment shows that ocean oxygen levels in a key area were higher during the Miocene warm period, some 16 million years ago when the Earth's temperature was hotter than it is today.
Published Do warmer temperatures make turtles better mothers?



Warmer temperatures are known to make more turtle eggs become female hatchlings, but new research shows that those females also have a higher capacity for egg production, even before their sex is set. This finding may explain why many animals besides turtles have temperature-dependent sex determination and why the system persists, despite seeming like a risky strategy. It may also provide a troubling glimpse of what could lie ahead in a warming world.
Published The clue is in the glue -- Nature's secret for holding it together



An obscure aquatic plant has helped to explain how plants avoid cracking up under the stresses and strains of growth.
Published Unraveling the connections between the brain and gut



Engineers designed a technology to probe connections between the brain and the digestive tract. Using fibers embedded with a variety of sensors, as well as optogenetic stimulation, the researchers could control neural circuits connecting the gut and the brain, in mice.
Published Researchers reveal mechanism of protection against breast and ovarian cancer



Researchers have outlined the structure and function of a protein complex which is required to repair damaged DNA and protect against cancer.
Published Scientists discover new embryonic cell type that self-destructs to protect the developing embryo



Scientists have uncovered a new quality control system that removes damaged cells from early developing embryos.
Published The speed of life: A zoo of cells to study developmental time



Researchers have used an unprecedented stem cell zoo to compare six different mammalian species and their developmental time.
Published AI reveals hidden traits about our planet's flora to help save species



Machine learning can help extract important information from the huge numbers of plant specimens stored in herbaria, say scientists.
