Science has not kept pace with aquaculture
Aquaculture—the farming of fish, shellfish, and other aquatic animals for food—has reached unprecedented levels of growth in recent years, but largely without consideration of its impact on individual animals, finds a new analysis by a team of researchers.
Radicalization to extremist ideologies is often triggered by negative life events
People who radicalize to extremist ideologies often are triggered by negative life events or exposure to propaganda, and those who escape from extreme groups frequently are aided by an individual or group that intervenes to help them reject the philosophy, according to a new RAND Corporation study.
How pathogenic bacteria weather the slings and arrows of infection
Infectious diseases are a leading cause of global mortality. During an infection, bacteria experience many different stresses—some from the host itself, some from co-colonizing microbes and others from therapies employed to treat the infection. In this arms race to outwit their competition, bacteria have evolved mechanisms to stay alive in the face of adversities. One such mechanism is the...
MOF-based sensor for water quality testing
The United Nations Sustainable Development Goals, Number 6, addresses the need for access to clean water and sanitation for all. In the worldwide situation, one in three people do not have access to safe drinking water, and two out of five do not have basic hand-washing facilities with soap and water.
Fungi could manipulate bacteria to enrich soil with nutrients
A team of researchers from the Boyce Thompson Institute (BTI) has discovered a distinct group of bacteria that may help fungi and plants acquire soil nutrients. The findings could point the way to cost-effective and eco-friendly methods of enriching soil and improving crop yields, reducing farmers' reliance on conventional fertilizers.
Realtime imaging of female gamete formation in plants
Scientists from Nagoya University, Yokohama City University and Chubu University have developed a system which enables the live imaging of the formation of the female gamete in plants.
Hidden diversity of coral more important for conservation than previously thought
In recent years, advancements in DNA sequencing have exposed a large amount of hidden diversity in reef-building corals: species that appear identical to one another but are genetically distinct. Typically ignored as they are invisible to the naked eye, a team of researchers at the California Academy of Sciences and The University of Queensland, along with over a dozen international collaborators,...
Dual-bed catalyst enables high conversion of syngas to gasoline-range liquid hydrocarbons
Gasoline, the primary transportation fuel, contains hydrocarbons with 5-11 carbons (C5-11) and is almost derived from petroleum at present.
In-situ nanoscale insights into the evolution of solid electrolyte interphase shells
The interfacial decomposition products forming the so-called solid-electrolyte interphase (SEI) during the first charging/discharging significantly determine the electrochemical performances of lithium (Li) batteries. To date, the dynamic evolutions, chemical compositions, stabilities and the influencing factors of SEI films have captured the attention of many.
Oxygen-promoted synthesis of armchair graphene nanoribbons on Cu(111)
On-surface synthesis has received great attention as a method to create atomically-precise one-dimensional (1D) and two-dimensional (2D) polymers with intriguing properties. In particular, graphene nanoribbons (GNRs), a category of quasi-1D nanomaterials derived from graphene, have been widely studied due to their tunable electronic properties and potential applications in semiconductor devices,...
Depositing iron species inside ZSM-5 to oxidize cyclohexane to cyclohexanone
The directly catalytic oxidation of alkanes has high atomic economy and application value to form corresponding chemical organic products such as alcohols, aldehydes, ketones and carboxylic acid. It is challenging to achieve efficient and selective oxidation of alkanes under mild conditions due to the inert C-H bonds of alkanes.
Exploring the evolution of Earth's habitability regulated by oxygen cycle
As an essential material for the survival and reproduction of almost all aerobic organisms, oxygen is closely related to the formation and development of complex organisms. A recent review provides a systematic overview of the latest advances in the oxygen cycle at different spatial and temporal scales and the important role that oxygen plays in shaping our current habitable Earth.
Adjusting interactions help some of California's wild bee populations survive
Across California's Central Valley, under stress from large-scale agriculture and climate change, native bee species that are flexible in their pollination behavior when around other wild bee populations appear best suited for survival in shrinking habitats.
In coal-addicted Bulgaria, EU climate goal faces hurdles
With its belching smokestacks, Bulgaria's Bobov Dol coal plant symbolises the type of industry the EU aims to eliminate—and the hurdles it faces in its green transition.
ProteinGAN: A generative adversarial network that generates functional protein sequences
Proteins are large, highly complex and naturally occurring molecules can be found in all living organisms. These unique substances, which consist of amino acids joined together by peptide bonds to form long chains, can have a variety of functions and properties.
Getting CubeSats moving: M-Argo will be first to traverse interplanetary space under its own power
ESA's M-Argo mission will be the first CubeSat to traverse interplanetary space under its own power. Due to launch in 2024-5, the suitcase-sized spacecraft will travel to a near-Earth asteroid, up to 150 million km away.
New book explains how famous mummy was murdered

Suez Canal blockage: How cargo ships like Ever Given became so huge, and why they're causing problems
The six-day blockage of the Suez Canal by a megaship named Ever Given came to an end on March 29 after salvage teams used dredging and tug boats to heave the vessel back into operation.
A streamlined approach to determining thermal properties of crystalline solids and alloys
In a September 2020 essay in Nature Energy, three scientists posed several "grand challenges"—one of which was to find suitable materials for thermal energy storage devices that could be used in concert with solar energy systems. Fortuitously, Mingda Li—the Norman C. Rasmussen Assistant Professor of Nuclear Science and Engineering at MIT, who heads the department's Quantum Matter Group—was...
An overview of cultural research in animals and its implications for conservation efforts
Andrew Whiten, an evolutionary and developmental psychologist with the University of St. Andrews in the U.K., has published a Review piece in the journal Science giving an overview of evidence for culture in many species of animals, including insects and fish. In his paper, he notes that the long-held notion that only humans have culture has long been dispelled.
