New approach to improve nitrogen use, enhance yield, and promote flowering in rice

Nitrogen fertilizers (applied as nitrate, NO3-, or ammonium, NH4+) improve the amount of grain produced per acre, but nitrogen runoff and volatilization pollute the water and the air. Production of nitrogen fertilizers also uses fossil fuels. Show More Summary

Being raised in greener neighborhoods may have beneficial effects on brain development

(University of California - Los Angeles) A study by ISGlobal, a center supported by the 'la Caixa' Banking Foundation, in collaboration with Hospital del Mar and UCLA's Fielding School of Public Health, shows for the first time that exposure to green space during childhood is associated with beneficial structural changes in the developing brain.

New approach to improve nitrogen use, enhance yield, and promote flowering in rice

(American Society of Plant Biologists) Using nitrogen fertilizer increases crop yields, but excess runoff causes environmental pollution. Moreover, in grains such as rice, large amounts of nitrogen fertilizer can delay flowering, leaving the crop vulnerable to late-season cold weather. Show More Summary

An under-the-radar immune cell shows potential in fight against cancer

(University of British Columbia) One of the rarest of immune cells, Type-2 innate lympoid cells might be a potent weapon in slowing the spread of cancer to other parts of the body. Though known primarily for their role in causing asthma, University of British Columbia scientists found that implanted cancers metastasize much more easily in mice lacking ILC2 cells.

World’s coral reefs face new peril from beneath within decades

The world’s coral reefs, already enduring multiple threats from bleaching to nutrient run-off from farming, also face another challenge – this time from below. New research, published in the journal Science on Friday, has found the sediments on which many reefs are built are 10 times more sensitive to the acidifying oceans than the living corals themselves. […]

Our acid oceans will dissolve coral reef sands within decades

Carbonate sands on coral reefs will start dissolving within about 30 years, on average, as oceans become more acidic, new research published today in Science shows. Carbonate sands, which accumulate over thousands of years from the breakdown of coral and other reef organisms, are the building material for the frameworks of coral reefs and shallow […]

Coral reefs at risk of dissolving as oceans get more acidic: study

OSLO (Reuters) – Coral reefs could start to dissolve before 2100 as man-made climate change drives acidification of the oceans, scientists said on Thursday. Acidification will threaten sediments that are building blocks for reefs. Corals already face risks from ocean temperatures, pollution and overfishing. Show More Summary

Coral reefs at risk of losing building material by end of century

A new study suggests that by 2050, most coral reefs around the world are at risk of experiencing constant depletion of one of their building blocks – calcium carbonate sediments. A few reefs are already experiencing this state, called net sediment dissolution, which greatly hinders the growth of coral reefs and consequently impacts the health […]

Neuroscientists identify the smallest units that make up the vocalisation of marmoset monkeys

From short 'tsiks' and 'ekks' to drawn-out 'phees' – all the sounds produced by marmoset monkeys are made up of individual syllables of fixed length: that is the result of a study by a team of researchers headed by Dr. Steffen Hage of the Werner Reichardt Centre for Integrative Neuro-science (CIN) at the University of Tübingen. Show More Summary

Coral reefs will transition to net dissolving before end of century

Ocean acidification refers to the lowering of the ocean’s pH due to the uptake of anthropogenic CO2 from the atmosphere. Coral reef calcification is expected to decrease as the oceans become more acidic. Dissolving calcium carbonate (CaCO3) sands could greatly exacerbate reef loss associated with reduced calcification but is presently poorly constrained. Here we show […]

Macroalgal response to a warmer ocean with higher CO2 concentration

Highlights • Decreased pH had a positive effect on short-term production of the studied species. • Algae with tropical affinity increased their production at higher temperatures. • Respiration rates were higher at the lower temperature treatments. Show More Summary

Fearmongering is scary, not genetic technologies themselves

Australia's gene technology regulations have not been revised since 2001 - despite many game-changing advances in genetic technologies over the past 17 years.

Effects of carbamazepine and cetirizine under an ocean acidification scenario on the biochemical and transcriptome responses of the clam Ruditapes philippinarum

Highlights • Drugs were bioconcentrated at both pH conditions (7.8 and 7.5). • Uptake and BCF of CTZ decreased comparing low pH (7.5) with control pH (7.8). • No oxidative stress was induced by drug exposure and/or pH. • Exposure to drugs or low pH changed mRNA levels. • Drug exposure and ocean acidification interaction […]

Researchers film bacteria using melee combat to steal antibiotic resistance genes

Researchers at the University of California San Diego Center for Microbiome Innovation have identified the mechanism by which a clinically relevant bacterium may gain antibiotic resistance, and have come up with a model for predicting the conditions under which it spreads. Show More Summary

Assassin bug's venom system packs a deadly double

Venom researchers from The University of Queensland have uncovered a unique and complex venom system within the tiny assassin bug.

Do firehawks intentionally spread fire to aid in food collection?

"This is not a new discovery," said Mark Bonta, assistant teaching professor of earth sciences at Penn State Altoona, when asked about the firehawks.

Disease-bearing mosquitoes gain from shrinkage of green spaces

Urbanization and the resulting shrinkage of green spaces in cities are a boon for mosquitoes that transmit pathogens, including Aedes aegypti (dengue) and Culex quinquefasciatus (lymphatic filariasis). More adapted to urban areas, they benefit from the decline in populations of other mosquito species.

Playing both ends: Amphibian adapted to varied evolutionary pressures

Caecilians are serpent-like creatures, but they're not snakes or giant worms. The limbless amphibians, related to frogs and salamanders, favor tropical climates of Africa, Asia and the Americas. Most live in burrows of their own making; some are aquatic.

Sierra Nevada gets Clearance for First DreamChaser Mission to ISS in Late 2020

NASA has given Sierra Nevada Corporation (SNC) formal approval for the company’s first cargo mission to the International Space Station in late 2020. SNC announced Feb. 7 that it had received “authority to proceed” on that mission using the company’s Dream Chaser vehicle. Show More Summary
