A researcher found that artificial intelligence can accurately detect and diagnose colorectal cancer from tissue scans as well or better than pathologists, according to a new study.
Researchers have developed an artificial material which can respond to its environment, independently make a decision, and perform an action not directed by a human being. For example, a drone making a delivery might evaluate its environment including wind direction, speed or wildlife, and automatically change course in order to complete the delivery safely. The material incorporates 3 main...
Heat from a comet exploding just above the ground fused the sandy soil into patches of glass stretching 75 kilometers, a new study found.
Malaria, a pathogen transmitted into blood by mosquitoes in tropical climates, is typically thought of as a blood and liver infection. However researchers have detected antibodies primarily made in response to infections in the mucous membranes -- in such areas as the lungs, intestines, or vagina -- in study participants with malaria.
Pinnipeds -- a group including seals, sea lions and walruses -- are relatively recently derived marine mammals that evolved from terrestrial carnivorans and reentered the marine environment. Their recent adaptations to an amphibious lifestyle make their evolutionary anatomy of particular interest.
The obstacles and opposition to introducing a carbon tax in Canada underscore how difficult it will be to find enough support for a global carbon pricing system, Prime Minister Justin Trudeau told world leaders gathered for the COP26 global climate...

Pinnipeds—a group including seals, sea lions and walruses—are relatively recently derived marine mammals that evolved from terrestrial carnivorans and reentered the marine environment. Their recent adaptations to an amphibious lifestyle make their evolutionary anatomy of particular interest to Baylor University researcher Sarah Kienle, Ph.D., assistant professor of biology.
An astronomer from NSF's NOIRLab has teamed up with a geologist from California State University, Fresno, to make the first estimates of rock types that exist on planets orbiting nearby stars. After studying the chemical composition of "polluted" white dwarfs, they have concluded that most rocky planets orbiting nearby stars are more diverse and exotic than previously thought, with types of rocks...
Around 12,000 years ago, something scorched a vast swath of the Atacama Desert in Chile with heat so intense that it turned the sandy soil into widespread slabs of silicate glass. Now, a research team studying the distribution and composition of those glasses has come to a conclusion about what caused the inferno.
In the media, a prevalent narrative is that Donald Trump lost the 2020 elections because of the way he handled the COVID-19 pandemic. Several researchers determined that Trump would have won the electoral vote and lost the popular vote, as he did in 2016, if the pandemic had not occurred or if it had been mitigated.
The COP26 climate summit has made it clear that reducing methane emissions is a key priority for policymakers. Here's a look at what's happening in Canada on that front.
Enjoy the Moon and planets after sunset all month, plus a lunar eclipse! A partial lunar eclipse will be visible to much of the world on Nov. 18 and 19. Also, the familiar stars of Northern Hemisphere winter (or Southern summer) are returning to late night skies. In particular, note that several destinations of NASA's Lucy mission are located near the Pleiades. Additional information about...
NASA is exploring a concept for a new fleet of mini-rovers that can work together to solve problems and make decisions as a unit. If one fails or gets stuck somewhere, the others could carry on without it. As part of the Cooperative Autonomous Distributed Robotic Exploration (CADRE) project, NASA engineers are designing compact, mobile robots the size of a shoebox (for comparison, Perseverance...
Being with friends and family may be a positive experience for some voles but it is merely tolerable to others, suggests a study published today in eLife.
This is the second article in a series of three. The first focused on the importance of making businesses more future-ready and how to work through common obstacles on the path to digitization. We also discussed how modernizing on-premises infrastructure as part of a hybrid cloud approach can best be managed via hyperconverged infrastructure (HCI), enabling modernization that blends the best of...
Liquid crystals already provide the basis for successful technologies like LCD displays, and researchers continue to create specific kinds of liquid crystals for even better optical devices and applications.
In the last years, a new viral tomato disease has emerged, threatening tomato production worldwide. This is caused by the Tomato brown rugose fruit virus (ToBRFV), a member of a devastating group of plant viruses called tobamoviruses. ToBRFV overcomes all known tobamovirus resistance in tomato, including the one conferred by Tm-22, a resistance gene responsible for the stable resistance to these...
Women exposed to smoke from landscape fires during pregnancy are more likely to give birth to babies with low or very low birth weights, according to new findings.
Being with friends and family may be a positive experience for some voles but it is merely tolerable to others, suggests a new study.
Scientists have discovered that a deadly parasite, known to cause ill health in pregnant women and immunocompromised patients, could potentially be used to treat various types of tumors.
A new analysis suggests that the movement of plankton and plankton-eating fish play a central role in driving local spikes of extreme biological productivity in tropical coral reefs, creating "sweet spots" of abundant fish. Renato Morais of James Cook University in Townsville, Australia, and colleagues present these findings in a study publishing November 2nd in the open-access journal PLOS...
When two galaxies collide, the supermassive black holes at their cores release a devastating gravitational "kick," similar to the recoil from a shotgun. New research led by CU Boulder suggests that this kick may be so powerful it can knock millions of stars into wonky orbits.
Dozens of countries on Tuesday joined a United States and European Union pledge to cut emissions of methane—a potent greenhouse gas—by at least 30 percent this decade, in a major commitment for climate action.
Dutch physicist who helped to identify the links between human-induced climate change and extreme weather disastersGeert Jan van Oldenborgh, who has died aged 59 of multiple myeloma, was co-founder and member of a team of scientists who identified — at speed and while politically a hot topic — the links between human-induced climate change and forest fires, heatwaves, drought, flood and other...
The bloom of a giant and stinky Sumatran flower nicknamed the "corpse plant" because it smells like a dead body is drawing huge crowds to a Southern California botanical garden.
Incorporating energy efficiency measures can reduce the amount of storage needed to power the nation's buildings entirely with renewable energy, according to a recent analysis.
The potential of DNA structural properties in single-molecule electronics has finally been harnessed by researchers in a single-molecule junction device that shows spontaneous self-restoring ability. Additionally, the device, based on a 'zipper' DNA configuration, shows unconventionally high electrical conductivity, opening doors to the development of novel nanoelectronic devices.
Move over, Hollywood—science fiction is getting ready to leap off the big screen and enter the real world. While recent science fiction movies have demonstrated the power of artificially intelligent computer programs, such as the fictional character J.A.R.V.I.S. in the Avenger film series, to make independent decisions to carry out a set of actions, these imagined movie scenarios could now be...
One of the major challenges the world faces is how to provide sustainable sources of energy that meet societal needs as the global population continues to grow. Bioenergy crops have garnered increasing attention as a renewable energy source, but their productivity has not yet been fully realized.

After an anterior cruciate ligament reconstruction surgery, it's common to experience quadriceps weakness, which was thought to be caused primarily by muscle atrophy, or shrinkage.
Earth's atmosphere has a unique ability to cleanse itself by way of invisible molecules in the air that act as minuscule cleanup crews. The most important molecule in that crew is the hydroxyl radical (OH), nicknamed the 'detergent of the atmosphere' because of its dominant role in removing pollutants. New research will aid in building more accurate computer models of OH. The study has important...
The haze that blurs a blue sky or a beautiful skyline is caused by particulate matter, often made from pollution, less than 2.5 microns wide. Despite their microscopic size, PM2.5 are responsible for more than 4 million premature deaths every year. A new study shows that the pollution caused by consumption in the world's biggest economies leads to half of those deaths.
Natural sounds, and bird song in particular, play a key role in building and maintaining our connection with nature - but a major new study reveals that the sounds of spring are changing, with dawn choruses across North America and Europe becoming quieter and less varied. An international team of researchers led by the University of East Anglia (UEA) developed a new technique, combining...
