CRISPR-BEST prevents genome instability

Scientists have developed CRISPR-BEST, a new genome editing tool for actinomycetes. It addresses the problem of genome instability caused by DNA double-stranded breaks in current CRISPR-technologies.

How to make biocatalysts immortal

Oxygen threatens sustainable catalysts that use hydrogen to produce electricity in fuel cells. Researchers have now developed a way to combat this.

Liquifying a rocky exoplanet

A hot, molten Earth would be around 5% larger than its solid counterpart. The difference between molten and solid rocky planets is important for the search of Earth-like worlds beyond our Solar System and the understanding of Earth itself.

New large-sized insect species discovered in tropical forest

Scientists have studied the diversity of tropical parasitoid wasps for years. Parasitoid wasps are among the most species rich animal taxa on Earth, but their tropical diversity is still poorly known. Recently, the research group sampled Afrotropical rhyssine wasps, which are among the largest wasps.

Nobel Prize in Chemistry 2019: Lithium-ion batteries

The Nobel Prize in Chemistry 2019 is being awarded to John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino "for the development of lithium-ion batteries."

Predicting the impact of climate change on bridge safety

Climate change will increase the frequency and intensity of natural hazards like flooding. In turn, floodwaters erode a bridge's foundation, creating scour holes that compromise the integrity of the structure. But to date, it's been possible to quantify that scour risk. A new model developed by civil engineering researchers takes a holistic approach combining climatology, hydrology, structural engineering, and risk assessment to determine the effects of climate change on bridges.

Study recommends special protection of emperor penguins

Researchers recommend additional measures to protect and conserve one of the most iconic Antarctic species -- the emperor penguin (Aptenodyptes forsteri).

Buying less is better than buying 'green' -- for the planet and your happiness

A new study found that people who consume less are happier than those who engage in other pro-environmental consumer behaviors, like buying environmentally friendly products.

Meet the 'mold pigs,' a new group of invertebrates from 30 million years ago

Fossils preserved in Dominican amber reveal a new family, genus and species of microinvertebrate from the mid-Tertiary period, a discovery that shows unique lineages of the tiny creatures were living 30 million years ago.

The deeper these octopuses live, the wartier their skin

Deep beneath the ocean's surface, surprisingly cute pink octopuses creep along the seafloor. Some of them have super warty skin, and some are smooth. Scientists weren't sure if these octopuses were even members of the same species, and they didn't know how to explain the differences in the animals' looks. But a new study shows that the deeper in the ocean the octopuses live, the bumpier their skin and the smaller their bodies.

Cheap as chips: Identifying plant genes to ensure food security

Scientists have developed a new approach enabling researchers to more efficiently identify the genes that control plant traits. This method will enable plant breeders and scientists to develop more affordable, desirable, and sustainable plant varieties. The application will be most valuable for the fruit, vegetable and grain crops that are critical for global food security and human nutrition.

Study of past California wildfire activity suggest climate change will worsen future fires

A new study finds that climate has been the dominant controller of wildfire activity in the Sierra Nevada region of the past 1,400 years, suggesting that future climate change is poised to make fires worse.

Rice irrigation worsened landslides in deadliest earthquake of 2018

Irrigation significantly exacerbated the earthquake-triggered landslides in Palu, on the Indonesian island of Sulawesi, in 2018, according to an international study.

Believing in climate change doesn't mean you are preparing for climate change

Researchers found that although coastal homeowners may perceive a worsening of climate change-related hazards, these attitudes are largely unrelated to a homeowner's expectations of actual home damage.

Identifying a cyanobacterial gene family that helps control photosynthesis

A new study has identified a family of genes in cyanobacteria that help control carbon dioxide fixation.

Heat waves could increase substantially in size by mid-century

Scientists found that by mid-century, in a middle greenhouse emissions scenario, the average size of heat waves could increase by 50%. Under high greenhouse gas concentrations, the average size could increase by 80% and the more extreme heat waves could more than double in size.

Urban, home gardens could help curb food insecurity, health problems

Food deserts are an increasingly recognized problem in the United States, but a new study indicates urban and home gardens -- combined with nutrition education -- could be a path toward correcting that disadvantage.

Dual approach needed to save sinking cities and bleaching corals

Local conservation can boost the climate resilience of coastal ecosystems, species and cities and buy them time in their fight against sea-level rise, ocean acidification and warming temperatures, a study by scientists suggests. In all but extreme situations, these interventions significantly buffer the impacts of climate change and can buy sinking cities and bleaching corals time to adapt until the beneficial impacts of global emissions reductions kick in.

Machine learning helps plant science turn over a new leaf

Researchers have developed machine-learning algorithms that teach a computer system to analyze three-dimensional shapes of the branches and leaves of a plant. The study may help scientists better quantify how plants respond to climate change, genetic mutations or other factors.
