New technique reduces nicotine levels, harmful compounds simultaneously in tobacco

Posted: 12 Jul 2021 10:12 AM PDT

Researchers have developed a new technique that can alter plant metabolism. Tested in tobacco plants, the technique showed that it could reduce harmful chemical compounds, including some that are carcinogenic. The findings could be used to improve the health benefits of crops.

Mapping extreme snowmelt and its potential dangers

A new software improves data-independent acquisition proteomics by providing a computational workflow that permits highly sensitive and accurate data analysis.

Electric delivery vehicles: When, where, how they’re charged has big impact on greenhouse gas emissions

Posted: 12 Jul 2021 09:22 AM PDT

The transportation sector is the largest contributor to greenhouse gas emissions in the United States, and a lot of attention has been devoted to electric passenger vehicles and their potential to help reduce those emissions.

The fine nose of storks

Posted: 12 Jul 2021 09:22 AM PDT

The sharp eyes of an eagle, the extraordinary hearing of an owl - to successfully find food, the eyes and ears of birds have adapted optimally to their living conditions. Until now, the sense of smell has played a rather subordinate role. When meadows are freshly mowed, storks often appear there to search for snails and frogs. Researchers have now studied the birds' behavior and discovered that the storks are attracted by the smell of the mown grass. Only storks that were downwind and could thus perceive the smell reacted to the mowing. The scientists also sprayed a meadow with a spray of green leaf scents released during mowing. Storks appeared here as well. This shows that white storks use their sense of smell to forage and suggests that the sense of smell may also play a greater role in other birds than previously thought.

You can snuggle wolf pups all you want, they still won't 'get' you quite like your dog

Posted: 12 Jul 2021 09:22 AM PDT

You know your dog gets your gist when you point and say 'go find the ball' and he scampers right to it. This knack for understanding human gestures may seem unremarkable, but it's a complex cognitive ability that is rare in the animal kingdom. New research comparing dog puppies to human-reared wolf pups offers some clues to how dogs' unusual people-reading skills came to be.

Coastal ecosystems worldwide: Billion-dollar carbon reservoirs

Posted: 12 Jul 2021 09:21 AM PDT

Australia's coastal ecosystems alone save the rest of the world costs of around 23 billion US dollar a year by absorbing CO2 from the atmosphere. Coastal ecosystems such as seagrass meadows, salt marshes and mangrove forests make an important contribution to mitigating climate change.

A fermented-food diet increases microbiome diversity and lowers inflammation, study finds

Posted: 12 Jul 2021 09:21 AM PDT

A diet rich in fermented foods enhances the diversity of gut microbes and decreases molecular signs of inflammation, according to researchers.

Ecologists develop a novel forensic tool for detecting laundering of critically endangered cockatoos

Posted: 12 Jul 2021 09:21 AM PDT

Ecologists have applied stable isotope techniques to determine whether birds in the pet trade are captive or wild-caught, a key piece of evidence required in many cases to determine whether a trade is legal or not. They have applied this technique to the yellow-crested cockatoo, a critically endangered species from Indonesia/Timor-Leste with a global population of fewer than 2,500.

Let crop residues rot in the field -- it's a climate win

Posted: 12 Jul 2021 09:21 AM PDT

Plant material that lies to rot in soil isn't just valuable as compost. In fact, agricultural crop residue plays a crucial role in sequestering carbon, which is vital for reducing global CO2 emissions.

Human environmental genome recovered in the absence of skeletal remains

Posted: 12 Jul 2021 09:21 AM PDT

Ancient sediments from caves have already proven to preserve DNA for thousands of years. The amount of recovered sequences from environmental sediments, however, is generally low, which complicates analyses. A study has now successfully retrieved three mammalian environmental genomes from a single soil sample of 25,000 years BP obtained from the cave of Satsurblia in the Caucasus (Georgia).

Rise in Southeast Asia forest clearance increasing greenhouse gases

Posted: 12 Jul 2021 09:21 AM PDT

Forest clearance in Southeast Asia is accelerating, leading to unprecedented increases in carbon emissions, according to new research. The findings show that forests are being cut down at increasingly higher altitudes and on steeper slopes in order to make way for agricultural intensification.

Sea-level rise may worsen existing San Francisco Bay Area inequities

Posted: 12 Jul 2021 09:21 AM PDT

Researchers examined the number of households unable to pay for damages from coastal flooding to reveal how sea-level rise could threaten the fabric of Bay Area communities over the next 40 years.

Every spot of green space counts

An international study of parks and gardens finds even the humble roadside verge plays an important role in the environment and for our health.

Scientists blueprint bacterial enzyme believed to 'stealthily' suppress immune response

Posted: 12 Jul 2021 06:22 AM PDT

Scientists have produced the first fine-detail molecular blueprints of a bacterial enzyme known as Lit, which is suspected to play a 'stealthy' role in the progression of infection by reducing the immune response. Blueprints such as these allow drug designers to uncover potential weaknesses in bacterial arsenals as they seek to develop new therapeutics that may help us win the war against antibiotic resistance.
