International quantum year launches in style at UNESCO headquarters in Paris

More than 800 researchers, policy makers and government officials from around the world gathered in Paris this week to attend the official launch of the International Year of Quantum Science and Technology (IYQ). Held at the headquarters of the United Nations Educational, Scientific and Cultural Organisation (UNESCO), the two-day event included contributions from four Nobel prize-winning physicists – Alain Aspect, Serge Haroche, Anne l’Huillier and William Phillips.

Opening remarks came from Cephas Adjej Mensah, a research director in the Ghanaian government, which last year submitted the draft resolution to the United Nations for 2025 to be proclaimed as the IYQ. “Let us commit to making quantum science accessible to all,” Mensah declared, reminding delegates that the IYQ is intended to be a global initiative, spreading the benefits of quantum equitably around the world. “We can unleash the power of quantum science and technology to make an equitable and prosperous future for all.”

The keynote address was given by l’Huillier, a quantum physicist at Lund University in Sweden, who shared the 2023 Nobel Prize for Physics with Pierre Agostini and Ferenc Krausz for their work on attosecond pulses. “Quantum mechanics has been extremely successful,” she said, explaining how it was invented 100 years ago by Werner Heisenberg on the island of Helgoland. “It has led to new science and new technology – and it’s just the beginning.”

Not Science Fiction: Scientists Discover Mysterious “Zombie” Fungus Infecting Spiders in Ireland’s Caves

Scientists identified a new fungus, Gibellula attenboroughii, infecting cave spiders in Ireland. The fungus manipulates spider behavior, resembling “zombie-ant fungi.”

Dr. Harry Evans, Emeritus Fellow at CAB International, led a team of scientists—including experts from the Natural History Museum of Denmark and the Royal Botanic Gardens, Kew—in a study to identify a fungus discovered on a spider during the filming of the BBC Winterwatch series in Northern Ireland.

Through morphological and molecular analysis, the researchers confirmed the fungus as a previously unknown species.

Barbecue grill approach helps researchers understand puzzling Rayleigh–Bloch waves

So-called Rayleigh–Bloch waves can release an enormous amount of energy that can damage technical systems under certain circumstances. They only exist below a precisely defined cut-off frequency; above this, they disappear abruptly. Strangely enough, however, there are isolated high frequencies at which they can also be detected.

Mathematicians from the Universities of Augsburg and Adelaide have recently proposed an explanation for this puzzling phenomenon. Together with researchers from the University of Exeter, they have now been able to prove experimentally that their theory is indeed correct. The study has just been published in the journal Communications Physics.

Suppose you had a gigantic barbecue grill that could easily accommodate several hundreds of sausages. Then, you could not only use it to invite your children’s entire school to a barbecue. The numerous stainless steel struts aligned parallel to each other are also ideal for generating Rayleigh–Bloch waves.

Dopamine Drives Aggression Learning in Males

Summry: New research reveals that dopamine plays a crucial role in teaching young male mice to fight, with the chemical’s influence diminishing as they gain experience. In novice fighters, boosting dopamine increased aggression, while blocking it stopped them from fighting.

However, experienced fighters showed no changes in behavior regardless of dopamine manipulation, highlighting the role of experience in shaping aggression. The study identifies the lateral septum as a key brain region for “aggression learning” in males, but no similar effect was observed in females.

How philosophical thinking shapes healthy habits in preschoolers

Teaching healthy lifestyle behaviors to very young children is foundational to their future habits. Previous evidence suggests that philosophical thinking (PT) can help children develop moral values, cognitive skills, and decision-making abilities.

A recent study published in BMC Public Health explores the role of PT in assisting preschoolers to adopt healthy lifestyle behaviors. Some of these habits include being physically active, eating healthy, washing hands properly, having respect for one’s body, being aware of one’s needs, feelings, abilities, and responsibilities, getting sufficient sleep, and sharing one’s thoughts with others.

From chalkboards to chatbots: Transforming learning in Nigeria, one prompt at a time

“AI helps us to learn, it can serve as a tutor, it can be anything you want it to be, depending on the prompt you write,” says Omorogbe Uyiosa, known as “Uyi” by his friends, a student from the Edo Boys High School, in Benin City, Nigeria. His school was one of the beneficiaries of a pilot that used generative artificial intelligence (AI) to support learning through an after-school program.

A few months ago, we wrote a blog with some of the lessons from the implementation of this innovative program, including a video with voices from beneficiaries, such as Uyi. Back then, we promised that, if you stayed tuned, we would get back with the results of the pilot, which included an impact evaluation. So here we are with three primary findings from the pilot!

BIOTECHNOLOGY in the Future: 2050 (Artificial Biology)

Biopunk androids replicants.

What happens when humans begin combining biology with technology, harnessing the power to recode life itself.

What does the future of biotechnology and genetic engineering look like? How will humans program biology to create organ farm technology and bio-robots. And what happens when companies begin investing in advanced bio-printing, artificial wombs, and cybernetic prosthetic limbs.

Other topic include: bioengineered food and farming, bio-printing in space, new age living bioarchitecture (eco concrete inspired by coral reefs), bioengineered bioluminescence, cyberpunks and biopunks who experiment underground — creating new age food and pets, the future of bionics, corporations owning bionic limbs, the multi-trillion dollar industry of bio-robots, and bioengineered humans with super powers (Neo-Humans).

As well as the future of biomedical engineering, biochemistry, and biodiversity.

CRISPR Explained: Fixing DNA Mistakes

How could CRISPR help cure diseases? Feng Zhang, Professor of Biological Engineering at MIT, describes how CRISPR works like a search box for DNA. Using matching RNA proteins, it can find specific spots on the DNA where a gene needs to be edited or repaired. Through this method, it might be possible to go into the human genome and fix the genes that cause sickle cell disease, blindness, or neurodegeneration! How Does CRISPR Work? With Feng Zhang: https://youtu.be/ylgg7yZMJSs Among the world’s largest science centers, the Museum of Science engages millions of people each year to the wonders of science and technology through interactive exhibitions, digital programs, giant screen productions, and preK – 12 EiE® STEM curricula through the William and Charlotte Bloomberg Science Education Center. Established in 1830, the Museum is home to such iconic experiences as the Theater of Electricity, the Charles Hayden Planetarium, and the Mugar Omni Theater. Around the world, the Museum is known for digital experiences such as Mission: Mars on Roblox, and traveling exhibitions such as the Science Behind Pixar.
