Even though KRAS4B is the dominant form in cancer, the KRAS4A mutant is also oncogenic, and it is even more active. In the words of the authors, "KRAS4AG12V alone, in the absence of KRAS4B, can induce lung cancer and metastasis in 20 percent of individuals. Our results suggest that for therapies to be effective, the two KRAS isoforms should be targeted."

New research has found marine seismic surveys used in oil and gas exploration are not impacting the abundance or behaviour of commercially valuable fishes in the tropical shelf environment in north-western Australia.

Researchers at Stanford and the University of Naples study how bubbles form and eventually burst using high-speed cameras and analytical modeling, revealing a new popping process.

Triggered by the 2015-16 El Niño, extreme drought and associated mega-wildfires caused the death of around 2.5 billion trees and plants and emitted 495 million tonnes of CO2 from an area that makes up just 1.2 per cent of the entire Brazilian Amazon rainforest, and 0.01 per cent of the whole biome.

Led by Université de Montréal, an international team of anthropologists, geographers and earth scientists looks to the past to assess how different cultures have - and will - adapt to global warming.

A new approach to analyse satellite measurements of Earth's cloud cover reveals that clouds are very likely to enhance global heating.

Research conducted at the Sharon Eccles Steele Center for Translational Medicine (SCTM) at the University of Utah's John A. Moran Eye Center explains why people carrying a block of genetic variants strongly associated with the development of age-related macular degeneration (AMD) may develop the disease and identifies a potential therapeutic pathway for slowing or even reversing disease progression.

By uprooting carbon trapped in soil, wild pigs are releasing around 4.9 million metric tonnes of carbon dioxide annually across the globe, the equivalent of 1.1 million cars.

Parenting deficiencies have long been blamed for the vocabulary gap between low-income children and their more affluent peers. But new research implicates the economic context in which parenting takes place -- in other words, the wealth gap.

Freiburg researchers discover a signaling protein that controls the assembly of human cellular "power plants"

New Curtin University-led research has called into question existing health advice that mothers wait a minimum of two years after giving birth to become pregnant again, in order to reduce the risk of adverse pregnancy outcomes, such as preterm and small-for-gestational age births.

Political anger in the U.S. has reached a fever pitch in recent years. Now, new research shows that ordinary voters may begin to mirror the angry emotions of the politicians they read about in the news.

Electrical activity in the motor cortex of rats transforms from redundant to complex over the span of four days shortly after birth. Sleep twitches guide this metamorphosis, according to new research published in JNeurosci.

A new robotic neck brace from researchers at Columbia Engineering and their colleagues at Columbia's Department of Otolaryngology may help doctors analyze the impact of cancer treatments on the neck mobility of patients and may help guide their recovery.

What's a hungry marine microbe to do when the pickings are slim? It must capture nutrients - nitrogen, phosphorus, or iron - to survive, yet in vast expanses of the ocean, nutrients are extremely scarce. One ingenious solution to this challenge is reported this week in Proceedings of the National Academy of Sciences.

An RNA modification may offer protection against non-alcoholic fatty liver, a condition that results from a build-up of fat in the liver and can lead to advanced liver disease, according to a new study by UCLA researchers. The modification may also explain why females tend to have higher fat content in the liver.

A new study shows that DNA duplication has been vitally important throughout the evolutionary history of gymnosperms, a diverse group of seed plants that includes pines, cypresses, sequoias, ginkgos and cycads.

Researchers from The University of Texas at Austin have found a low-cost way to solve one half of the water-splitting equation to produce hydrogen as clean energy -- using sunlight to efficiently split off oxygen molecules from water. The finding represents a step forward toward greater adoption of hydrogen as a key part of our energy infrastructure.

Did you know multiple sclerosis (MS) means multiple scars? New research shows that the brain and spinal cord scars in people with MS may offer clues to why they developprogressive disability but those with related diseases where the immune system attacks the central nervous system do not. In a study published in Neurology, Mayo Clinic researchers and colleagues assessed if inflammation leads to permanent scarring in these three diseases.

A Canadian study reveals that lesbian, gay and bisexual youth are more likely than heterosexual youth to increase their use of cannabis following an increase in their symptoms of depression.
