Researchers have found that one method of reducing greenhouse gas emissions is available, affordable, and capable of being implemented right now. Nitrous oxide, a potent greenhouse gas and ozone-depleting substance, could be readily abated with existing technology applied to industrial sources.
Open access publisher Frontiers is participating in the One Sustainable Health for All Forum 2023 co-organized by the One Sustainable Health for All Foundation and the French Development Agency (AFD). The event, which takes place 5-7 July 2023 in Lyon, France, focuses on inclusive and adaptive systems for health and is part of the larger goal to contribute to achieving the United Nations Sustainable Development Goals (SDGs) for 2030.
A new method for connecting neurons in neuromorphic wetware has been developed. The wetware comprises conductive polymer wires grown in a three-dimensional configuration, done by applying square-wave voltage to electrodes submerged in a precursor solution. The voltage can modify wire conductance, allowing the network to be trained. This fabricated network is able to perform unsupervised Hebbian learning and spike-based learning.
By Deborah Pirchner, Frontiers science writer Image: Jasper Nance /Flickr ( CC BY-NC-ND 2.0 ) When a creature’s stress levels decrease because of the presence of a companion, it is known as social buffering. In highly social animals, such as mammals and birds, this phenomenon is well studied. Now, researchers have examined social buffering in rattlesnakes and found that the presence of a second snake significantly reduced rattlesnakes’ change in heart rates after they experienced disturbance.
Researchers have made major strides in confirming the source of dust in early galaxies. Observations of two Type II supernovae, Supernova 2004et (SN 2004et) and Supernova 2017eaw (SN 2017eaw), have revealed large amounts of dust within the ejecta of each of these objects. The mass found by researchers supports the theory that supernovae played a key role in supplying dust to the early universe.
A study using a synthetic 'minimal cell' organism stripped down to the 'bare essentials' for life demonstrates the tenacity of organism's power to evolve and adapt, even in the face of an unnatural genome that would seemingly provide little flexibility.

Scientists used seismic data discovered Earth's inner core displays a variety of textures that it acquired will it formed from within the fluid outer core. The data set was generated over the past 27 years by a network of seismometers set up to enforce the nuclear test ban treaty.
Researchers have developed a soft, flexible, wireless device to monitor and treat heart disease and dysfunction in the days, weeks or months following traumatic heart-related events. And, after the device is no longer needed, it harmlessly dissolves inside the body, bypassing the need for extraction.
Researchers have developed a metallic gel that is highly electrically conductive and can be used to print three-dimensional (3D) solid objects at room temperature.
An antisense therapy restores production of the protein FMRP in cell samples taken from patients with fragile X syndrome. This breakthrough was possible because of the novel findings, also presented in the study, that aberrant alternative splicing of messenger RNA (mRNA) plays a principal role in fragile X syndrome, the most common form of inherited intellectual disability and the most frequent single-gene cause of autism.
A large formation of granite discovered below the lunar surface likely was formed from the cooling of molten lava that fed a volcano or volcanoes that erupted early in the Moon's history -- as long as 3.5 billion years ago.
Birds are the only group of dinosaurs that survived the asteroid-induced mass extinction 66 million years ago. But not all the birds alive at the time made it. Why the ancestors of modern birds lived while so many of their relatives died has been a mystery that paleontologists have been trying to solve for decades. Two new studies point to one possible factor: the differences between how modern birds and their ancient cousins molt their feathers.
