What it’s like to live in the world’s most innovative countries

The BBC speaks to residents and travellers in some of the top-ranked countries on the 2024 Global Innovation Index to find out how cutting-edge technology benefits day-to-day life.

With the rise of AI, self-driving cars and wi-fi connected appliances, it can feel like innovation is everywhere these days. But certain countries are known for developing cutting-edge technologies that benefit residents and visitors alike.

To dive into those countries making the most impact in these areas, the World Intellectual Property Organisation recently released its 2024 Global Innovation Index, ranking 130 economies based on measures like their education system, technology infrastructure and knowledge creation (like patents filed or mobile apps created).

Want to design the car of the future? Here are 8,000 designs to get you started

MIT engineers have released DrivAerNet++, an open-source dataset of over 8,000 car designs, to accelerate automotive innovation using AI. This dataset, featuring detailed aerodynamic data, aims to enhance fuel efficiency and electric vehicle range, promoting sustainable car design advancements.

Car design is an iterative and proprietary process. Carmakers can spend several years on the design phase for a car, tweaking 3D forms in simulations before building out the most promising designs for physical testing. The details and specs of these tests, including the aerodynamics of a given car design, are typically not made public. Significant advances in performance, such as in fuel efficiency or electric vehicle range, can therefore be slow and siloed from company to company.

MIT engineers say that the search for better car designs can speed up exponentially with the use of generative artificial intelligence tools that can plow through huge amounts of data in seconds and find connections to generate a . While such AI tools exist, the data they would need to learn from have not been available, at least in any sort of accessible, centralized form.

But now, the engineers have made just such a dataset available to the public for the first time. Dubbed DrivAerNet++, the dataset encompasses more than 8,000 car designs, which the engineers generated based on the most common types of cars in the world today. The study is published on the arXiv preprint server.

Roboticists develop a bird-like robot that can jump into the air to launch itself into flight

A team of roboticists at École Polytechnique Fédérale de Lausanne, working with a colleague from the University of California, has designed, built and demonstrated a bird-like robot that can launch itself into flight using spring-like legs.

The group describes their in a paper published in the journal Nature. Aimy Wissa, an at Princeton University, has published a News & Views piece in the same journal issue suggesting possible ways the innovation could be used in real-world applications.

Some types of drones, such as those with rotors, can rise straight up off the ground—others that are powered with forward-facing or engines that push exhaust out the back must either race along a runway or catapult to get airborne. For this new project, the research team developed a new for getting such craft into the air—jumping using spring-like legs.

Giant cyborg cockroaches could be the search and rescue workers of the future

Fitzgerald says cyborg search and rescue beetles or cockroaches might be able to help in disaster situations by finding and reporting the location of survivors and delivering lifesaving drugs to them before human rescuers can get there.

But first, the Australian researchers must master the ability to direct the movements of the insects, which could take a while. Fitzgerald says that although the work might seem futuristic now, in a few decades, cyborg insects could be saving lives.

He’s not the only roboticist creating robots from living organisms. Academics at the California Institute of Technology (Caltech), for example, are implanting electronic pacemakers into jellyfish to control their swimming speed. They hope the bionic jellies could help collect data about the ocean far below the surface.

Brain Age Models Offer Insights into Early Development Trajectories

Summary: A new study highlights how brain age models can track healthy infant development and reveal environmental influences. Using MRI data from over 600 term and preterm infants, researchers trained machine learning models to predict brain age and identify gaps between predicted and actual ages.

These brain age gaps can indicate whether an infant’s development is faster or slower than expected, with maternal age emerging as a significant influencing factor. Advanced brain development was linked to better cognitive abilities but poorer emotional regulation, suggesting that following normative developmental trajectories may be ideal.

Tiny 15 mm robot from China zips past speed records in robotics

Chinese researchers have created the BHMbot-B, a 15 mm long microrobot with quick forward and backward movements, which is ideal for navigating small places.

The robot effectively switches between forward and backward movement by aligning the vibratory motions of its magnet, cantilever, and linkages using vibration mode transition control.

The Beihnag University team claims that the device combines a battery, a control circuit for wireless operation, and two electromagnetic actuators for a high load capacity.

Building a “Google Maps” for Biology: Human Cell Atlas Revolutionizes Medicine

New research from the Human Cell Atlas offers insights into cell development, disease mechanisms, and genetic influences, enhancing our understanding of human biology and health.

The Human Cell Atlas (HCA) consortium has made significant progress in its mission to better understand the cells of the human body in health and disease, with a recent publication of a Collection of more than 40 peer-reviewed papers in Nature and other Nature Portfolio journals.

The Collection showcases a range of large-scale datasets, artificial intelligence algorithms, and biomedical discoveries from the HCA that are enhancing our understanding of the human body. The studies reveal insights into how the placenta and skeleton form, changes during brain maturation, new gut and vascular cell states, lung responses to COVID-19, and the effects of genetic variation on disease, among others.
