"These tropical cyclone changes, plus pronounced coastal sea level rise might compound potential societal impacts."

Dr Zhang cautioned that the sensitivity of tropical cyclones to warming has a high level of uncertainty but he said the risk from these storms could still increase even with moderate levels of warming.

Certainly, the authors argue that this course is not set in stone and that dramatic reductions in carbon emissions over the next decade particularly, could alter the outcome.

"The control over this is the temperature gradient between the tropics and the poles, and that's very tightly linked to overall climate change," said Dr Studholme.

"By end of this century, the difference in that gradient between a high emission scenario and a low emission scenario is dramatic. That can be very significant in terms of how these hurricanes play out."

In relation to hurricanes and tropical cyclones, the authors said they had "high confidence" that the evidence of human influence has strengthened.

"The proportion of intense tropical cyclones, average peak tropical cyclone wind speeds, and peak wind speeds of the most intense tropical cyclones will increase on the global scale with increasing global warming," the IPCC said.

The new research published on Wednesday makes use of multiple strands of evidence to show that tropical cyclones in future are likely to occur over a wider range than previously thought.

"What we've done is make explicit the links between the physics going on within storms themselves and the dynamics of the atmosphere at the planetary scale," said Dr Studholme.

"This is a hard problem because this physics isn't well simulated in numerical models run on modern computers."

The likely expansion of these storms poses a significant danger to the world, especially when the other impacts of warming come into play.

"Tropical cyclones in the mid-latitude band could experience other changes such as slower motion and heavier rainfall," said Dr Gan Zhang, previously an atmospheric scientist at Princeton University and NOAA who wasn't involved in the new paper.

The aerospace engineering and computer science student at Stanford University was born with fibular hemimelia, where part or all of the leg bone is missing. Mary had her left leg amputated below the knee as a baby and uses a prosthetic. "It's one of my favourite things about me now," she says.

As the plane went over the top of the arc and gravity disappeared the crew felt weightless for the first time - an extraordinary sensation.

"It's not that you're floating up, it's that you're no longer getting pulled down," Sina says excitedly. "You're sitting on the ground, you push off so much as with one finger and you're floating."

Sina had wondered what floating blind would be like when his constant point of reference - gravity - disappeared.

"I was expecting disorientation," he says, "[but] once I started getting used to zero-g I immediately found it comfortable and easy for me to push off with less force and to use a little more finesse."

Each crew member worked with MIT on specific experiments in-line with their disability to see how the industry could move forward, inclusively.

Sina tried using audio beacons to navigate by sound.

"Guess what? We couldn't hear them," he says, saying it is far louder than a commercial flight. "That's a learning."

But something unexpected happened.

When the command "feet down" was yelled - signalling the end of the parabola - "many of us in the blind and low vision crew were able to find our mats," he says.

"That was just really a testament, both to our internal working memory and all the solutions we've had to come up with on earth."

The failure of the audio beacons has opened up other conversations.

Could bone-conducting headphones be used? Or maybe vibrotactile feedback - the sensation of vibration - by having a device placed on someone's skin where the noise could be felt?

Mary's experiment gave her permission to cartwheel.

Sina believes "ableism" is what is holding the industry back.

"There's this built-in belief that persons with disabilities are somehow less than and therefore all of the other considerations aren't brought to the table," he says, saying that needs to stop.

Mary says there are simple ways to increase inclusion. Astronauts speak several languages, so why not make American Sign Language (ASL) one of those?

Some of the crew signed during the mission, but interpreting the words was difficult when people were floating upside down.

Solutions are already being bandied about - perhaps a drone could detect signs and display them the right way up for the receiver?

It's food for thought.

Next time, Sina personally wants to explore "the sonification of a gyroscope," where sound and vibration could give him a sense of movement in a particular direction.

He says flight suits could have these features built-in, benefiting everyone, not just blind astronauts.

"Mary will be looking at something and doesn't need to glance up to know that she's actually experiencing a little bit of spin, because her left hip is vibrating.

"We need to get away from thinking of this as that which is done in excess. These are necessary considerations that we simply haven't been making yet."

Mission Astro Access isn't alone in this space race. The European Space Agency called for six para-astronauts earlier this year and disability advocate Eddie Ndopu has signed several NDA's about space travel.

Having returned to earth, Mission Astro Access' 12 ambassadors will now also "rethink life on earth" and encourage greater inclusivity within the science, technology, engineering, and mathematics (STEM) sectors.

"The thing that resonates with me the most is that we really don't need many accommodations," Mary says, whose mind often drifts back to October.

"Every single night I lay in bed and I just try and remember that feeling of complete weightlessness. It's a feeling I know I'll be chasing for a long time."

Scientists have compiled the world's oldest family tree from human bones interred at a 5,700-year-old tomb in the Cotswolds, UK.

Analysis of DNA from the tomb's occupants revealed the people buried there were from five continuous generations of one extended family.

Most of those found in the tomb were descended from four women who all had children with the same man.

The right to use the site was based on descent from one man.

But people were buried in different parts of the tomb based on the first-generation matriarch they were descended from.

This suggests that the first-generation women held a socially significant place in the memories of this community. The Neolithic tomb, or "cairn", at Hazleton North in Gloucestershire has two L-shaped chambers, one facing north and the other south.

The tomb dates to an important period just after farming was introduced to Britain by people whose ancestors had - several thousand years earlier - spread through Europe from Anatolia (modern Turkey) and the Aegean. The work will help researchers understand family dynamics among these Stone Age people and learn more about their culture.

"Hopefully this will be the first of many such studies," said Prof Reich. "It really makes vivid the lives of these people... who lived in this place a very long time ago."

There are also indications that "stepsons" were adopted into the family, the researchers say - males whose mother was buried in the tomb but not their biological father, and whose mother had also had children with a male related to the original founder.
