Yawning and deep breathing each have different effects on the movement of fluids in the brain, and each of us may have a distinct yawning "signature"

We pick the sci-fi novels we’re most looking forward to reading this month, from a new Brandon Sanderson to  the latest from Makana Yamamoto

In the early 1800s, Denmark’s government, medical community, church leaders and school teachers all united to promote the new smallpox vaccine, which led to a remarkably quick elimination of the disease in the capital

Members of the New Scientist Book Club give their take on Sierra Greer's award-winning science-fiction novel Annie Bot, our read for February – and the needle swings wildly from positive to negative

In this extract from the February read for the New Scientist Book Club, we meet the protagonist of Tim Winton’s Juice, driving across a scorched landscape in a future version of Australia

The New Scientist Book Club's February read is Tim Winton's novel Juice, set in a future Australia that is so hot it is almost unliveable. Here, the author lays out his reasons for writing it – and why he doesn't see it as dystopian

Elizabeth Hohmann is very interested in faeces, and spends her days sifting through stools to find those that could make the biggest difference to other people's health

Researchers at KAIST have developed a breakthrough technology that could dramatically improve our ability to image black holes and other distant objects. The team created an ultra precise reference signal system using optical frequency comb lasers to synchronise multiple radio telescopes with unprecedented accuracy. This laser based approach solves long standing problems with phase calibration that have plagued traditional electronic methods, particularly at higher observation frequencies.

It’s 2050 and you’re living on Venus. This might come as a surprise due to the planet’s crushing surface pressures (~92 times of Earth) and searing surface temperatures (~465 degrees Celsius/870 degrees Fahrenheit), which is equivalent to ~900 meters (3,000 feet) underwater and hot enough to melt lead, respectively. But you’re not living on the surface. Instead, you’re safe and sound inside a lava tube habitat scanning data from the latest orbiter images while sipping on some habitat-made espresso.

Solar flares are one of the most closely watched processes in solar physics. Partly that’s because they can prove hazardous both to life and equipment around Earth, and in extreme cases even on it. But also, it’s because of how interestingly complex they are. A new paper from Pradeep Chitta of the Max Planck Institute for Solar System Research and his co-authors, available in the latest edition of Astronomy & Astrophysics, uses data collected by ESA’s Solar Orbiter spacecraft to watch the formation process of a massive solar flare. They discovered the traditional model used to describe how solar flares form isn’t accurate, and they are better thought of as being caused by miniaturized “magnetic avalanches.”

A new study led by researchers from Aarhus University showed that amino acids spontaneously bond in space, producing peptides that are essential to life as we know it. Their findings suggest that the building blocks of life are far more common throughout space than previously thought, with implications for astrobiology and SETI.

Interval cancers are aggressive tumours that grow during the interval after someone has been screened for cancer and before they are screened again, and AI seems to be able to identify them at an early stage
