Multitasking microbes: Scientists engineer bacteria to make two valuable products from plant fiber      (via sciencedaily.com)     Original source 

Researchers have engineered bacteria that can produce two chemical products at the same time from underutilized plant fiber. And unlike humans, these multitasking microbes can do both things equally well. The discovery could help make biofuels more sustainable and commercially viable.

Reduced air pollution during pandemic points to way to preserve Himalayan glaciers      (via sciencedaily.com)     Original source 

Reducing air pollution to levels similar to those during the coronavirus pandemic could protect the glaciers in the Himalayas and prevent them from disappearing by the end of the century. This is the conclusion reached by an international research team analyzing the situation during the COVID-19 lockdown in 2020.

New study examines the relationship between the rate of wound healing, the circadian rhythm, and 'hair' on cells      (via sciencedaily.com)     Original source 

Nearly every organism on Earth follows a natural circadian rhythm that is coded by your cell's clock genes, which do exactly as you suspect from the name: regulate your body's rhythm on a 24-hour basis. Most cells in mammalian bodies have cilia of some sort, which are hair-like structures that perform a variety of functions such as movement for motile cilia and aiding in structure in function for non-motile, or primary, cilia. The primary cilia also act as a sensory organ for the cell, a function which has illuminated the primary cilia's potential role in the healing process and how bodies heal at a different rate according to our circadian rhythm. In this research, the role of the primary cilia, biological clock and wound healing is explored.

Scientists provide recipe to halve pollution from food production      (via sciencedaily.com)     Original source 

A major report has put forward solutions to halve nitrogen pollution from agriculture and the food system in Europe, including reducing meat and dairy consumption, fertilizer use and food waste. Inefficiencies in farms, retail and wastewater practices mean that the nitrogen use efficiency of the food system in Europe is only 18%, leaving most of the remainder leaking into air, water and soils. The new report, Appetite for Change, has been produced by a group of researchers coordinated by the UK Centre for Ecology & Hydrology (UKCEH), the European Commission, Copenhagen Business School and the National Institute for Public Health and the Environment (RIVM) of The Netherlands.

Single-celled protists in the guts of animals thrive without the 'powerhouse of the cell'      (via sciencedaily.com)     Original source 

Almost all eukaryotic organisms, from plants and animals to fungi, can't survive without mitochondria -- the 'powerhouses of the cell,' which generate chemical energy using oxygen. However, a new study finds that multiple members of the oxymonads, a group of single-celled protists that live inside the guts of termites and other animals, have evolved to live quite happily without them.

Low economic growth can help keep climate change within the 1.5 °C threshold      (via sciencedaily.com)     Original source 

A new study shows that economic growth rates make a big difference when it comes to prospects for limiting global warming to 1.5 °C, as per the Paris Agreement. A recent study shows that pursuing higher economic growth may jeopardize the Paris goals and leave no viable pathways for humanity to stabilize the climate. On the contrary, slower growth rates make it more feasible to achieve the Paris goals.

Snowflakes swirling in turbulent air as they fall through a laser light sheet      (via sciencedaily.com)     Original source 

A winter wonderland calls to mind piles of fluffy, glistening snow. But to reach the ground, snowflakes are swept into the turbulent atmosphere, swirling through the air instead of plummeting directly to the ground. Researchers found that regardless of turbulence or snowflake type, acceleration follows a universal statistical pattern that can be described as an exponential distribution.

Exoplanets' climate -- it takes nothing to switch from habitable to hell      (via sciencedaily.com)     Original source 

The Earth is a wonderful blue and green dot covered with oceans and life, while Venus is a yellowish sterile sphere that is not only inhospitable but also sterile. However, the difference between the two bears to only a few degrees in temperature. A team of astronomers has achieved a world's first by managing to simulate the entirety of the runaway greenhouse process which can transform the climate of a planet from idyllic and perfect for life, to a place more than harsh and hostile. The scientists have also demonstrated that from initial stages of the process, the atmospheric structure and cloud coverage undergo significant changes, leading to an almost-unstoppable and very complicated to reverse runaway greenhouse effect. On Earth, a global average temperature rise of just a few tens of degrees, subsequent to a slight rise of the Sun's luminosity, would be sufficient to initiate this phenomenon and to make our planet inhabitable.

15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems      (via sciencedaily.com)     Original source 

Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.
