People with Diabetes Have a Higher Dementia Risk

A US study has shown that people with type 1 diabetes are more likely to develop dementia than the general population, highlighting the importance of following up on brain health as we age.

Researchers from Boston University highlighted a potential way to thwart the disease in adults with diabetes. The findings were published on Monday at the Neurology Journal.

Type 1 diabetes is a chronic condition that affects the insulin making cells of the pancreas.

It is often diagnosed in children and adolescents, characterized by the pancreas producing little to no insulin, and often requires lifelong management, including daily insulin injections (or pumps) and frequent blood sugar monitoring to avoid dangerous complications.

The study was conducted on about 284,000 people, with an average age of 64, including 5,442 suffering from type 1 diabetes, and about 51,000 with type 2 diabetes.

Over an average of 2.4 years follow-up, the researchers examined cases of dementia, a brain disorder that slowly destroys a person's memory and thinking skills.

They found that 2,348 people developed dementia, including 144 with type 1 diabetes (2.6%) and 942 with type 2 diabetes (1.8%), while only 1,262 cases were recorded among non-diabetics (0.6%).

Taking into account factors such as age and education, researchers found that individuals with type 1 diabetes face a significantly elevated risk of developing dementia, with estimates suggesting they are up to three times more likely to develop the condition compared to those without diabetes, while individuals with type 2 diabetes were nearly twice as likely to develop dementia.

The researchers noted that previous studies have shown a link between type 2 diabetes and an increased risk of dementia, but the new findings suggest that this link may be stronger in people with type 1 diabetes.

Tunisia's summer this year was its hottest on record, the country's weather authority said Tuesday, following multiple heatwaves, water shortages and power cuts.

"The summer of 2026 was ranked the hottest in Tunisia since 1950," the year temperature records began, the National Meteorological Institute said.

The average temperature was about 2.9 degrees Celsius higher than the previous record, it added.

Although accustomed to scorching heat, Tunisia experienced a particularly gruelling summer this year, with July and August marked by "intense and prolonged heatwaves", the authority said.

Scientists attribute these episodes to climate change.

This summer also saw persistently high nighttime temperatures, the agency added.

The highest temperature was recorded in the central city of Kairouan, which reached 49.7 degrees Celsius in mid-July.

Temperatures also reached 49.2 degrees Celsius in Beja in the northwest, and in the south they reached 48.4 degrees Celsius in Tozeur.

Authorities have yet to provide figures on the health impact of the heatwaves, but a group representing young Tunisian doctors reported numerous deaths it said were caused by the heat.

A six-year-old Chinese girl has set a new women's world record for solving a 3x3 Rubik's Cube in just over four seconds, state media reported.

Young speedcuber Lian Yunzhi broke the women's 3x3 average world record twice this month at two World Cube Association certified competitions in Wuhan and Guangzhou, according to state broadcaster CCTV on Monday.

She posted averages of 4.52 and 4.27 seconds, after solving the Rubik's Cube five times.

Lian, who is from Chengdu, is "the first female speedcuber to average under 4.5 seconds", CCTV added.

A video CCTV posted showed the small girl wearing a red gingham bow on her head as she deftly turned and twisted a Rubik's Cube.

After solving the puzzle she places the cube on the table, claps her hands and pumps a fist into the air.

Nicknamed "Zhizhi", Lian was first introduced to the Rubik's Cube after being enrolled into a class as a child -- one of various extracurriculars alongside dance and music lessons, her mother Lin Yangxi, told local media outlets.

Lin "gradually realized" that cubing was an "excellent activity for fostering a child's comprehensive abilities" and shifted her focus towards it, she told Chengdu's Red Star News, according to AFP.

Her daughter has now mastered over 1,300 Rubik's Cube solving algorithms, practicing daily for two to three hours, Lin said.

Photos from Red Star News showed Lian's trophies displayed on a shelf in her home.

"Solving a Rubik's Cube improves focus, memory, logical thinking, spatial awareness, and helps develop a healthy mindset toward winning and losing," Lin said.

"It's not just about blindly memorizing formulas, but using logical reasoning to find optimal solutions," she added.

800,000 Bees stolen Across Australia in ‘Sophisticated’ Operation

An estimated 800,000 bees, worth tens of thousands of dollars, have been stolen from properties in far north Queensland.

The industry is already reeling from this month’s arrival of the varroa mite parasite, according to The Guardian.

Tom Bidner, an apiarist from the Atherton Tablelands, west of Cairns, said 44 colonies had been stolen from three different beekeepers.

“This isn’t over yet,” he said. “We’ve got so many colonies to get through. We’re still getting around and checking all our different sites.”

He estimated that each hive contained at least 20,000 bees, making it a total of more than 800,000.

The alleged thefts happened on multiple different properties in different areas and required a sophisticated operation and specialist equipment.

Rather than risking early detection by stealing an entire box, they took out what’s known as the brood box. That means the hive appears unchanged from afar.

“They’re rocking up with a truckload of gear, basically, and they’re transferring our frames into their boxes ... and putting our hives back together, so it doesn’t sort of alert any of the growers that it looks like someone’s been in and done such a thing,” Bidner said.

The thieves also didn’t take any honey, which was left on the hive.

He suspects that the culprits are probably people from within the industry.

The apiarists will lose not just the stolen insects but the value of the pollination contracts, which can run into the thousands of dollars, he said.

The grower will also lose out due to lower quality flowering.

Bidner said it was the biggest theft in memory, though far from the first.

It’s now the peak of the avocado season in far north Queensland, so hives are deployed at properties across the area on contracted pollination work for local growers. Others are just left on the side of the highway.

“Security wise, in the past, we’ve let the bees do the majority of the job ... from time to time, it definitely happens you’ll have someone try and come and tamper with a hive,” he said. “They usually get about 30 seconds into the job and they’re gone.”
