Equilibrium climate sensitivity -- how sensitive the Earth's climate is to changes in atmospheric carbon dioxide -- may be underestimated in individual climate models, according to a team of climate scientists.
A team of environmental and computation scientists is using deep neural networks, a type of machine learning, to replace the parameterizations of certain physical schemes in the Weather Research and Forecasting Model, an extremely comprehensive model that simulates the evolution of many aspects of the physical world around us.
Changes in groundwater millions of years ago created alternating layers of vivid yellow and brown in the mineral sphalerite, and those variations align with movements in Earth's orbit that impacted climate in the deep past, Penn State scientists found.
While the field of morphology—the study of the form and function of organisms—is centuries old, the last two decades have brought incredible leaps forward through the emergence of new technologies and genetic research methods. And the impact of these advances has been revolutionary for the scientists working to untangle the vast biodiversity and evolutionary paths of the world of insects.
An ant the size of a lion isn't as far-fetched as you would think. From as small as a sesame seed to the size of a big cat, ants come in all sizes—in augmented reality, at least.
According to the International Union for Conservation of Nature (IUCN), whale sharks are considered endangered, which means the species has suffered a population decline of more than 50% in the past three generations. The whale shark is only two classifications from being extinct. Improvements and conservation efforts are in place, but there is still a long way to go to protect these gentle...
The generation of species-specific singing in songbirds is associated with species-specific patterns of gene activity in brain regions called song nuclei, according to a study published November 12 in the open-access journal PLOS Biology by Kazuhiro Wada of Hokkaido University in Japan, and colleagues. According to the authors, the findings could be a promising step toward a better understanding...
Reproducibility is a major challenge in experimental biology, and with the increasing complexity of data generated by genomic-scale techniques this concern is immensely amplified. RNA-seq, one of the most widely used methods in modern molecular biology, allows in a single test the simultaneous measurement of the expression level of all the genes in a given sample. New research publishing November...
Bambang Hero Saharjo has received death threats for testifying against companiesA scientist who takes on the companies responsible for massive wildfires across Indonesia has won the prestigious John Maddox prize for standing up for science in the face of harassment, intimidation and lawsuits.Bambang Hero Saharjo, a fire forensics specialist at Bogor Agricultural University, gathers evidence for...
For the first time in the history of space exploration, scientists have measured the seasonal changes in the gases that fill the air directly above the surface of Gale Crater on Mars. As a result, they noticed something baffling: oxygen, the gas many Earth creatures use to breathe, behaves in a way that so far scientists cannot explain through any known chemical processes.
The snowman-shaped object that NASA's New Horizons probe flew past nearly a year ago on the solar system's icy fringe now has a Native American name: Arrokoth, a word that means "sky" in the Powhatan/Algonquian language. Arrokoth replaces earlier labels for the Kuiper Belt object, including the numerical designation 2014 MU69 and the nickname Ultima Thule, which turned out to be...

New research reveals that carbon nanotubes (CNTs) as a coating can both repel and hold water in place, a useful property for applications like printing, spectroscopy, water transport, or harvesting surfaces. When water is dropped on a CNT forest, the CNTs repel the water, and it forms a sphere. However, when flipped over, the drop does not fall to the ground but rather clings to the surface.
Researchers have developed a way to perform optical coherence tomography (OCT) in hard-to-reach areas of the body such as joints. The advance could help bring this high-resolution biomedical imaging technique to new surgical and medical applications.
Researchers have conducted a study to see if virtual reality can be used as an expressive tool in art therapy.
Why has the huge amount of rainfall that hit South Yorkshire had such a large impact on people and property?
Dave Morris on the collective power of research and Alastair Leake on the decline in moth populationsThe efforts of campaigners to highlight important issues can often be overlooked by a historical approach that focuses on individuals, often academics or politicians. An example is in the obituary of the biologist Victoria Braithwaite (Obituary, 9 November), which asserts that “until the early...
Boarding schools | Wellington college fees | Steve McQueen’s Year 3 project | Spike Milligan’s election advice | Shared ancestry | Parliamentary disillusionGeorge Monbiot’s article on boarding schools (Journal, 7 November) will have been a painful read for many, and may well have been painful for him to write. As a director for Boarding School Survivors Support (BSSS), I read of experience...
Since the Egyptian pyramids and the Roman Coliseum were built, mankind has been searching for an affordable, versatile building material, that can be easily manufactured and transported, and, above all, which is durable. Concrete, a mixture of water, cement and different kinds of minerals and rocks, has all these characteristics, which is why it is currently the most-used material in all sorts of...
Wearing a blue space suit with a UAE flag on one sleeve and a spaceship on the other, the first Emirati astronaut said Tuesday his mission highlighted a crucial issue—climate change.
For the first time, researchers show that deep learning algorithms perform similar to human experts when classifying blood samples from patients suffering from acute myeloid leukemia (AML). Their proof of concept study paves the way for an automated, standardized and on-hand sample analysis in the near future.
The oldest and thickest Arctic sea ice is disappearing twice as fast as ice in the rest of the Arctic Ocean, according to new research.
The research was conducted in Indonesia with the participation of young Indonesians who rated modern and traditional versions of tempeh, which has a long tradition in Indonesian cuisine and consists of beans fermented with a type of fungus.
Researchers uncover mechanisms in zebrafish heart regeneration that could lead to better treatments for babies in need of heart repair.
To facilitate the scientific community's ability to use L. crescens in citrus greening research, scientists have published an article that outlines, step-by-step, highly reproducible and detailed protocols that they have standardized for culturing L. crescens.
If you have trouble sleeping, you're not alone. New research finds more Americans have trouble falling asleep and staying asleep. The difficulties were most prevalent in people with healthy sleep length.
An international research collaboration from Poland, the UK and Russia has created a two-dimensional system—a thin optical cavity filled with liquid crystal—in which they trapped photons. As the properties of the cavity were modified by an external voltage, the photons behaved like massive quasiparticles endowed with a magnetic moment, called "spin," under the influence of an artificial...
A cornucopia of contradiction is dotting the landscape of Colorado's Front Range, at the foot of the Rocky Mountains.
Earlier this fall Dr. Scott Solomon presented the results of a huge heart drug study to an audience of fellow cardiologists in Paris.
