The legume family tree

Posted: 08 May 2021 05:29 AM PDT

The most comprehensive study of the family tree for legumes, the plant family that includes beans, soybeans, peanuts, and many other economically important crop plants, reveals a history of whole-genome duplications.

new mechanism for terminating transcription of DNA into RNA in bacteria

Posted: 07 May 2021 01:00 PM PDT

A bacterial protein helps to stop transcription -- the process of making RNA copies of DNA to carry out the functions of the cell -- by causing the cellular machinery that transcribes the DNA to pause at the appropriate spots in the genome.

The African wild dog: An ambassador for the world's largest terrestrial conservation area

Posted: 07 May 2021 08:20 AM PDT

The world's largest terrestrial conservation area is located in southern Africa and covers 520,000 square kilometers spanning five countries. A study now shows that the endangered African wild dog mostly remains within the boundaries of the Kavango-Zambezi Transfrontier Conservation Area (KAZA) when dispersing, thus highlighting the relevance of such a large-scale conservation initiative for maintaining key wildlife corridors of threatened species.

Distinct cell-to-cell communication processes controlled differently

Posted: 07 May 2021 08:20 AM PDT

Cells talk to each other to coordinate nutrition, waste removal, energy use, and, in some cases, disease progression. The cells that line the surfaces of organs or specific tissues, called epithelial cells, appear to speak two different languages - one for either side of the cell, according to a new study.

A deeper understanding of how cells move and stick together

A new article takes a step towards a deeper understanding of how cells adhere to each other and their motility.

Protecting coral from heat stress and coral bleaching

Posted: 07 May 2021 08:20 AM PDT

Coral bleaching, which is becoming stronger and more frequent due to heat stress, has already wiped out corals at many locations globally. With the help of a microbiome-targeting strategy, it could become feasible to help protect corals from heat stress.

Learning on the fly

Informatics experts have developed a new computational model that demonstrates a long sought after link between insect and mammalian learning.

Oat crops: Winning gene combination takes all

Posted: 07 May 2021 06:37 AM PDT

Researchers have traced the remaining last steps of the biological pathway that gives oats resistance to the deadly crop disease take-all.

Mathematical model predicting disease spread patterns

Posted: 06 May 2021 01:36 PM PDT

A team of environmental engineers, alerted by the unusual wealth of data published regularly by county health agencies throughout the pandemic, began researching new methods to describe what was happening on the ground in a way that does not require obtaining information on individuals' movements or contacts. A new model predicts where a disease will spread from an outbreak, in what patterns and how quickly.

Transforming atmospheric carbon into industrially useful materials

Posted: 06 May 2021 01:36 PM PDT

Plants are unparalleled in their ability to capture carbon from the air, but this benefit is temporary. Researchers have proposed a more permanent, and even useful, fate for this captured carbon by turning plants into a valuable industrial material called silicon carbide (SiC). A new study from scientists quantifies this process with more detail than ever before.

Surprising sand fly find yields new species of bacteria

Posted: 06 May 2021 01:36 PM PDT

Researchers made a surprising finding while examining areas where sand flies rear their young: a new species of bacteria that is highly attractive to pregnant sand flies. The findings could advance the production of ecologically safe baits or traps to reduce sand fly populations.

Researchers develop new metal-free, recyclable polypeptide battery that degrades on demand

Posted: 06 May 2021 01:36 PM PDT

The introduction of lithium-ion (Li-ion) batteries has revolutionized technology as a whole, leading to major advances in consumer goods across nearly all sectors. Battery-powered devices have become ubiquitous across the world. While the availability of technology is generally a good thing, the rapid growth has led directly to several key ethical and environmental issues surrounding the use of Li-ion batteries.

Rooted tree key to understanding bacterial evolution

Posted: 06 May 2021 11:21 AM PDT

An international team of researchers have found a new way to interpret the evolution of bacteria.
