Girls, boys have similar brains with equal math ability

Washington, Nov 9: There are no gender differences in math ability, according to a study that examined the brain development of young boys and girls.

The researchers, including those from Carnegie Mellon University in the US, conducted the first neuroimaging study to evaluate biological gender differences in math aptitude of young children.

The results of the study, published in the journal Science of Learning, revealed that there are no differences in the brain development of girls and boys, including how they processed math skills.

"This is an important reminder that humans are more similar to each other than we are different," said study co-author Alyssa Kersey from the University of Chicago in the US.

The study also noted that both boys and girls were equally engaged while watching educational videos.

"It's not just that boys and girls are using the math network in the same ways but that similarities were evident across the entire brain," Kersey said.

As part of the study, the researchers used functional MRI to measure the brain activity in 104 young children between the ages 3 to 10 (55 girls and 49 boys) while watching an educational video covering early math topics, like counting and addition.

They compared scans from the boys and girls to evaluate brain similarity.

The team also examined brain maturity in the children by comparing their scans to those taken from a group of adults -- 63 adults; 25 women -- who watched the same math videos.

The researchers also compared the results of the Test of Early Mathematics Ability -- a standardized test for children between 3 and 8 years of age -- from 97 participants (50 girls and 47 boys) to gauge the rate of math development.

Overall, the findings indicated that math ability was equivalent among the children, and did not show a difference in gender, or with age.

The researchers could also not find a gender difference between maths ability and brain maturity.

Jessica Cantlon, the lead researcher of the study from Carnegie Mellon University, said the society and culture likely are steering girls and young women away from science, technology, engineering, and mathematics (STEM) fields.

The researchers said families spend more time with young boys in play that involves spatial cognition, and many teachers also preferentially spend more time with boys during math class, predicting later math achievement.

Cantlon also suspected that children pick up on cues from their parent's expectations for math abilities.

"Typical socialization can exacerbate small differences between boys and girls that can snowball into how we treat them in science and math," Cantlon said.

"We need to be cognizant of these origins to ensure we aren't the ones causing the gender inequities," she said.

The current study looked at early childhood development using a limited set of math tasks, the researchers said.

Cantlon and her team plan to assess a broader array of math skills during childhood development such as spatial processing and memory and follow the children over many years.

The World Health Organisation on Wednesday said that anti-malarial drug hydroxychloroquine (HCQ) will return to the solidarity trial for the potential treatment of coronavirus disease.

At a press conference in the WHO headquarters in Geneva, Director General Tedros Adhanom Ghebreyesus said: "On the basis of the available mortality data, the members of the committee recommended that there are no reasons to modify the trial protocol. The Executive Group received this recommendation and endorsed continuation of all arms of the solidarity trial, including hydroxychloroquine."

The world health body had temporarily suspended the usage of HCQ from the solidarity trial for coronavirus treatment on May 25 soon after a study published in one of the most reliable medical journals, which had suggested that the drug could cause more fatalities among COVID-19 patients.

However, the WHO chief said that the decision was taken as a precaution while the safety data was reviewed.

Ghebreyesus also said that the Data Safety and Monitoring Committee will continue to closely monitor the safety of all therapeutics being tested in the solidarity trial.

"So far, more than 3,500 patients have been recruited in 35 countries. WHO is committed to accelerating the development of effective therapeutics, vaccines and diagnostics as part of our commitment to serving the world with science, solutions and solidarity," he said.

Soon after HCQ was suspended from the trial, the Indian government had said that the antimalarial drug has been known for its benefits for a long time and its usage will be continued on the frontline workers, including police and healthcare professionals, as prophylaxis. The government had also said that studies were being conducted and the drug would be included in the clinical trial also for the treatment of coronavirus disease.

US President Donald Trump also had strongly advocated the use of HCQ and called it a "game-changer". He went to the extent of saying that he had taken the medicine.

Launched by WHO and partners, solidarity trial is an international clinical trial to find an effective treatment for COVID-19, including drugs to slow the progression of the disease or improve survival. The trial, which enrols patients from different countries, "will compare four treatment options against standard of care to assess their relative effectiveness against COVID-19", said WHO.

The COVID-19 pandemic and the subsequent lockdown saw many people turning chefs overnight, but those who could not turned to online delivery of food. And not just any food, as per a new report, Indians "craved the most for Biryani" during the lockdown.

The "StatEATistics report: The Quarantine Edition" from food delivery platform Swiggy found that Indians ordered biryani over "5.5 lakh times" from their favourite restaurants.

The new normal might have opened a pandora's box of behavioral changes, but some old habits die hard like the love for Biryani, which took the top spot for overall orders. It was followed by butter naan and masala dosa at 3,35,185 and 3,31,423, respectively.

Biryani has topped the list of most ordered dishes for the fourth year in a row, the food delivery platform noted.

Indians didn't forget to indulge their sweet tooth in the uncertain months of lockdown. Their favourite comfort food during the lockdown period was the moist and decadent Choco Lava cake, ordered around 1,29,000 times.

"The humble Gulab Jamun (84,558) and chic Butterscotch Mousse cake (27,317) followed suit," said the report derived from Swiggy's order analysis in the past few months across cities that it is present in.

Also, as birthday parties moved to video calls, and virtual cake cutting sessions, according to the food delivery platform, it delivered nearly "1,20,000 cakes" to complete these celebrations.

According to the report, on average, "65,000 meal orders" were placed by 8 pm each day to make sure food arrived in time for dinner.

"It was the busiest hour for Swiggy delivery partners and restaurants. On average, they (customers) chose to tip Rs.23.65, with one particularly generous customer tipping Rs. 2500!," it added.

For those who only relied on home-made food during the quarantine, Swiggy delivered a whooping 323 million kgs of onions and 56 million kgs of bananas through its grocery section and hence ensured that its consumers were all stocked up.

That said, it also took care of the 'quick-fix meal' tribe -- consumers who resort to the evergreen college hacks of living on instant noodles.

"Around 3,50,000 packets of this ideal easy to cook meal were ordered during the lockdown," it said.

In all, Swiggy delivered 40 million orders across food, groceries, medicines and other household items during India's lockdowns. It also delivered over 73,000 bottles of sanitizers and hand wash along with 47,000 face masks as the definition of essentials' changed during these uncertain times.
