Major hurricanes expected to increase in 2023, researchers forecast

This story was originally published by Grist. Sign up for Grist’s weekly newsletter here.

Researchers at the University of Arizona, whose computer model has since 2014 accurately predicted hurricane activity, are calling for a very active hurricane season in 2023, after two years of relative calm. Of nine hurricanes forecast for the period between June and November, five are expected to be “major.”

Neuroeconomic framework provides insight into success and failure in smoking cessation

Recent research published in Psychiatry Research: Neuroimaging explored the relationship between choosing to delay gratification, neural functioning, and success or failure in smoking cessation. The findings indicate that individuals who chose immediate rewards rather than delayed ones are likelier to relapse and continue smoking. In addition, fMRI scans reveal differences in brain activity of those who choose to delay gratification compared to those who do not. This research can help practitioners predict who may struggle to quit smoking resulting in more robust and potentially successful int...

Unravelling DNA’s structure: a landmark achievement whose authors were not fairly credited

Seventy years ago, two male scientists, Francis Crick and James Watson, proclaimed they had discovered the secret of life: the structure of DNA. Since then, history has acknowledged how Rosalind Franklin was sidelined. But new archive evidence has cast doubt on the widely accepted narrative – that Franklin collected an all-important image but didn’t appreciate the meaning of what she was looking at.

This knowledge of DNA allowed for a deeper understanding of how DNA stores information and how it is replicated. It led to technologies such as DNA fingerprinting, gene sequencing, gene editing and personalized medicines.

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength – and the shorter the wavelength, the smaller the objects and details the light can be used to see.

DNA study of famed sled dog shows what made him so tough

The mounted body of the dog named Balto is on display at the Cleveland Museum of Natural History

Washington (AFP) - New York's Central Park has a statue dedicated to him, and there's even been a movie about him: a sled dog named Balto. Now he is the focus of a DNA study, 90 years after he died, to see what made the pooch so famously tough.

In 1925, this Siberian husky was part of an expedition in Alaska called the serum run, the goal of which was to bring life-saving medicine to young people in the remote town of Nome that were threatened by diphtheria.

Cognitive flexibility is essential to navigating a changing world – new research in mice shows how your brain learns new rules

Being flexible and learning to adapt when the world changes is something you practice every day. Whether you run into a new construction site and have to reroute your commute or download a new streaming app and have to relearn how to find your favorite show, changing familiar behaviors in response to new situations is an essential skill.

To make these adaptations, your brain changes its activity patterns within a structure called the prefrontal cortex – an area of the brain critical for cognitive functions such as attention, planning and decision-making. But which specific circuits “tell” the prefrontal cortex to update its activity patterns in order to change behavior have been unknown.

‘Got polio?’ messaging underscores a vaccine campaign’s success but creates false sense of security as memories of the disease fade in U.S.

Got Polio? Me neither. Thanks, Science.

Messages like this are used in memes, posters, T-shirts and even some billboards to promote routine vaccinations. As this catchy statement reminds people of once-feared diseases of the past, it – perhaps unintentionally – conveys the message that polio has been relegated to the history books.

Climate change behind 'devastating drought' in Horn of Africa, report says

A devastating drought that has struck the Horn of Africa could not have occurred without global warming, according to a new report released Thursday from an international team of climate scientists.

"Human-caused climate change has made agricultural drought in the Horn of Africa about 100 times more likely," said a summary of the report by the World Weather Attribution (WWA) group.

Deadly invader devastating Venezuelan coral reefs

An ominous shadow in the turquoise Caribbean waters off Venezuela comes from a deadly intruder -- a soft coral that experts say has caused one of the most destructive habitat invasions on record anywhere.

The Unomia stolonifera, native to Indonesia and the Indo-Pacific, is a pinkish type of pulse coral so called for its dance-like movements in the ocean currents.

Out of gas in orbit? This US space company is here to help

The US company Orbit Fab is aiming to produce the go-to "gas stations" in space, its CEO tells AFP, hoping its refueling technology will make the surging satellite industry more sustainable -- and profitable.

The solar panels typically attached to satellites can generate energy for their onboard systems such as cameras and radios, but can't help the orbiting objects adjust their positions, explains Daniel Faber, who co-founded the company in 2018.

'​I nearly died on their watch': Woman calls out Ted Cruz and John Cornyn during tense Senate abortion hearing

The Senate held a hearing on abortion Wednesday, though many Republicans didn't stick around for most of the testimony. Among the women who spoke was Amanda Zurawski, who nearly died after a medical emergency during her pregnancy meant that she couldn't get an abortion until she was closer to death.

The morning consisted of anti-abortion activists speaking out about the mental and emotional harm abortion has on women.

Scientific analysis of massive Twitter datasets links preferred pronouns in bios to left-wing politics

More and more users have been including preferred gender pronouns in their Twitter bios over time, according to new research published in the Journal of Quantitative Description: Digital Media. The research also provides evidence that words and phrases related to left-wing politics are more likely to be used alongside pronoun lists. Preferred pronouns refer to the pronouns (such as “she” and “her”) that an individual chooses to use for themselves, as opposed to the pronouns that are traditionally associated with their sex or gender. The use of preferred pronouns has become increasingly common ...

Ron Johnson doesn't get why anyone cares about climate change because the US is not Africa

Sen. Ron Johnson (R-WI), who narrowly won his recent reelection, complained that global climate change didn't really matter because his state could use a little less snow.

Speaking in the Senate Budget Committee Wednesday, economist Michael Greenstone addressed the health costs of climate change.
