Google’s X “moonshot factory” this week announced its latest graduate. Heritable Agriculture is a data-and machine learning-driven startup aiming to improve how crops are grown.

As the firm noted in an announcement post published Tuesday, plants are incredibly efficient and impressive systems. “Plants are solar powered, carbon negative, self-assembling machines that feed on sunlight and water,” Heritable wrote.

Yet agriculture puts a massive strain on the planet and its resources, accounting for around 25% of anthropogenic greenhouse emissions. It’s the planet’s largest consumer of groundwater and can lead to soil erosion and water pollution via pesticides, fertilizers, and other chemicals.

A study published in the journal One Earth explores how marine biodiversity conservation, human health and well-being are connected. The results suggest that marine protected areas can be good for both planet and people.

These areas of the ocean are legally recognized by governments as being important for marine conservation. They are protected by putting limits on human activity within and around them.

Once a government declares a marine protected area, you usually can’t live in it, fish, build a beach resort, start a fish farm or drill for oil in it. The rules vary from place to place, but the idea is to allow nature to flourish by limiting human activity as much as possible.

After more than a decade of work, researchers have reached a major milestone in their efforts to re-engineer life in the lab, putting together the final chromosome in a synthetic yeast (Saccharomyces cerevisiae) genome.

The researchers, led by a team from Macquarie University in Australia, chose yeast as a way to demonstrate the potential for producing foodstuffs that could survive the rigors of a changing climate or widespread disease.

It’s the first time a synthetic eukaryotic genome has been constructed in full, following on from successes with simpler bacteria organisms. It’s a proof-of-concept for how more complex organisms, like food crops, could be synthesized by scientists.

As their primary food source becomes less accessible, the bears enter longer fasting periods, leading to declining health and population numbers.

“A loss of sea ice means bears spend less time hunting seals and more time fasting on land,” said Louise Archer, a postdoctoral researcher and lead author of the study.

This prolonged fasting drains polar bears’ energy reserves, reducing their ability to reproduce and raise cubs. Without enough stored fat, female bears struggle to give birth and nurse their young. Over time, this energy deficit has led to a sharp population decline.

A team of researchers from Universidad Carlos III de Madrid (UC3M) has developed an innovative technique that allows the production of regular oil lenses of uniform size on the surface of water in a simple and reproducible fashion. The technique will facilitate the study of the behavior of oily substances dispersed on water surfaces.

This discovery is crucial for understanding the dispersion of some liquids floating on water and could have many applications in oil spill mitigation and the food and textile industries. The study is published in the journal Physical Review Letters.

The initial discovery, according to the researchers, was the result of an “accident” during the preparation of a routine experiment. “We were trying to coat a water surface with a thin layer of oil, but the result was unexpected: Instead of a uniform film, we obtained a series of identical and very small droplets, which aroused our curiosity,” explains Javier Rodríguez, from UC3M’s Department of Thermal and Fluids Engineering.

Quantum researchers from CSIRO, Australia’s national science agency, have demonstrated the potential for quantum computing to significantly improve how we solve complex problems involving large datasets, highlighting the potential of using quantum in areas such as real-time traffic management, agricultural monitoring, health care, and energy optimization.

By leveraging the unique properties of quantum computing, like superposition and entanglement, researchers compressed and analyzed a large dataset with speed, accuracy, and efficiency that traditional computers cannot match.

The work is published in the journal Advanced Science.

A study has introduced a novel bioprocess that transforms CO2 and electricity into single-cell protein (SCP), a sustainable food source rich in essential amino acids.

<div class=””> <div class=””><br />Amino acids are a set of organic compounds used to build proteins. There are about 500 naturally occurring known amino acids, though only 20 appear in the genetic code. Proteins consist of one or more chains of amino acids called polypeptides. The sequence of the amino acid chain causes the polypeptide to fold into a shape that is biologically active. The amino acid sequences of proteins are encoded in the genes. Nine proteinogenic amino acids are called “essential” for humans because they cannot be produced from other compounds by the human body and so must be taken in as food.<br /></div> </div>
