In the last decade, scientists discovered that blocking a key regulator of the immune system helped unleash the body's natural defenses against several forms of cancer, opening up a new era of cancer immunotherapy. Now scientists have essentially flipped this script and found that when impaired a molecularly similar regulator can cause the damaging immune system attacks on skin and organs that are...
People who take long naps during the day or sleep nine or more hours at night may have an increased risk of stroke, according to a new study.

Nearly a year and a half into its mission, Parker Solar Probe has returned gigabytes of data on the Sun and its atmosphere. Following the release of the very first science from the mission, five researchers presented additional new findings from Parker Solar Probe at the fall meeting of the American Geophysical Union on Dec. 11, 2019. Research from these teams hints at the processes behind both...
New evidence gleaned from Antarctic seashells confirms that Earth was already unstable before the asteroid impact that wiped out the dinosaurs.
In the last decade, scientists have made tremendous progress in understanding that groups of bacteria and viruses that naturally coexist throughout the human body play an important role in some vital functions like digestion, metabolism and even fighting off diseases. But understanding just how they do it remains a question.
What could Azteca ants in coffee farms in Mexico have in common with leopards' spots and zebras' stripes?
Accurately reconstructing the relationships between different species requires analyzing the sequences of a judiciously selected, and preferably large, sample of different genes. Hybrid capture with high-throughput sequencing, or Hyb-Seq, is a powerful tool for obtaining those gene sequences, but must be calibrated for each group analyzed to ensure an informative sample of genes are sequenced....
Blue Origin, the space company owned by Amazon CEO Jeff Bezos, launched the 12th crewless test of its New Shepard rocket on Wednesday, pushing the first flights with passengers to 2020.
A new find from Patagonia sheds light on the evolution of large predatory dinosaurs. Features of the 8-m long specimen from the Middle Jurassic suggest that it records a phase of rapid diversification and evolutionary experimentation.
Turbulence is one of the least understood phenomena of the physical world. Long considered too hard to understand and predict mathematically, turbulence is the reason the Navier-Stokes equations, which describe how fluids flow, are so hard to solve that there is a million-dollar reward for anyone who can prove them mathematically. But now, mathematicians have broken through the barrier and...
Findings on ice retreat across the global tropics clarifies how the low latitudes transformed during the end of the last ice age and can help current-day predictions of our own climate future.
The number of malnourished people is increasing worldwide. More than two billion people suffer from a lack of micronutrients. Infant mortality rates are unacceptably high. Against this background, there is a need for the global pooling of research efforts, more research funding and an international body for food security and agriculture that prepares policy decisions.
According to a new study led by a team from The University of New Mexico, centuries-old laws about the behavior of gas mixtures do not apply in the presence of shock waves. This finding could have potential impact on everything that involves mixtures of gases exposed to a shock wave, for example, during combustion in an engine.
A new study says Glacier National Park's iconic mountain goats are in dire need of 'air conditioning.'
An algorithm akin to the annoyingly helpful one that attempts to auto-complete text messages and emails is now being harnessed for a better cause. A group of researchers are using its pattern-recognition ability to identify microbial communities in the body by sifting through volumes of genetic code. Their method could speed the development of medical treatments for microbiota-linked ailments like...

By measuring the chemistry of fossilized seashells collected in Antarctica, researchers discovered that Earth was already experiencing carbon cycle instability before the asteroid impact that wiped out the dinosaurs.
A team of researchers has now identified a specific circuit in the brain that alters food impulsivity.
A newly discovered fossil whale represents a new species and an important step in the evolution of whale locomotion.
Scientists from Australia and the US have discovered and identified the genetic cause of a previously unknown human autoinflammatory disease. The researchers determined that the autoinflammatory disease, which they termed CRIA (cleavage-resistant RIPK1-induced autoinflammatory) syndrome, is caused by a mutation in a critical cell death component called RIPK1. The discovery suggests that compounds...
