Milkweed evolves ‘mind-blowing’ tactic to fight monarchs

Milkweed has found a new strategy in its epic evolutionary battle with monarch butterflies: upgrading its toxins to outmaneuver the monarch’s resistance. In a new study, published in the Proceedings of the National Academy of Sciences, researchers find that adding a small structural element containing nitrogen and sulfur to milkweed’s toxins circumvents monarchs’ ability to block them. The research sheds light on an underappreciated evolutionary tactic for plants: that not only can they increase their levels of toxicity, they can also structurally innovate to create new classes or subclasses of toxins.

“This structural innovation is a new axis for defining chemical toxins in the natural world,” said co-author Christophe Duplais, associate professor of entomology at Cornell AgriTech, in the College of Agriculture and Life Sciences (CALS). “This very simple modification makes a huge difference in terms of its ecological effect, because now this molecule is toxic to the monarch.”

Milkweed and monarchs have coevolved over millions of years, each building defenses and counter-defenses. One such defense is the monarchs’ ability to block milkweed’s toxins, called cardenolides, from binding to their target enzyme in the monarch’s cells. Monarchs have even evolved to sequester the toxins in their wings, to poison birds that peck at them.

SoulMate LLM accelerator evolves according to the specific characteristics of the user

While large language models (LLMs) like ChatGPT are adept at answering countless questions, they often remain unaware of a user’s minor habits or previous conversational contexts. This is why AI, despite being deeply integrated into our daily lives, can still feel like a “stranger.” Overcoming these limitations, researchers at KAIST, led by Professor Hoi-Jun Yoo from the Graduate School of AI Semiconductors, have developed the world’s first AI semiconductor, dubbed “SoulMate,” which learns and adapts to a user’s speech style, preferences, and emotions in real-time—becoming a true “digital soulmate.”

This technology is being hailed as a core semiconductor breakthrough that will accelerate the era of “hyper-personalized AI”—moving beyond “AI for everyone” to an AI that learns and responds to an individual’s unique conversational style and preferences. The work is published in the proceedings of the 2026 IEEE International Solid-State Circuits Conference (ISSCC).

Bacterial strain breaks decades-old bottleneck in chemotherapy drug manufacturing

An international team of researchers has achieved a breakthrough in the production of doxorubicin, a vital chemotherapy agent. The study identifies and resolves molecular “bottlenecks” that have limited the natural production of this drug for over 50 years. The research is published in Nature Communications.

Doxorubicin is a chemotherapy drug that was first approved for medical use in the 1970s. It is a cornerstone in treating various cancers, including breast cancer, bladder cancer, lymphomas and carcinomas, with over one million patients receiving the treatment annually. However, bacteria naturally produce this important drug very inefficiently. Consequently, the pharmaceutical industry has relied on expensive, multi-step semi-synthetic processes.

“We have uncovered several independent factors that limit the formation of doxorubicin,” says researcher Keith Yamada, Ph.D., from the University of Turku in Finland, a lead scientist on the study.

Enhancer dynamics and cellular architecture in the human spinal cord

Human spinal cord enhancer dynamics and cellular architecture.

The researchers present an innovative framework redefining human spinal cord cellular diversity through epigenetic configuration and spatial organization.

They identify unseen enhancer classes that define both stable cell-type identity and transitions between cells undergoing differentiation.

The authors also identify gene regulatory networks in glial cells that reorganize along the rostrocaudal axis, demonstrating anatomical differences in gene regulation.

The researchers demonstrate spatial organization of cells into distinct cellular networks and address the functional significance of this observation in the context of paracrine signaling. sciencenewshighlights ScienceMission https://sciencemission.com/Enhancer-dynamics

Kandror et al. present an innovative framework redefining human spinal cord cellular diversity through epigenetic configuration and spatial organization. They identify unseen enhancer classes, show cell-type-specific reconfiguration of gene regulatory networks along the rostrocaudal axis, and uncover cellular networks mediated by discrete paracrine signaling, challenging conventional definitions of cellular state.

Palm-sized superconducting magnet achieves 42 tesla, rivaling the world’s biggest

When we think of powerful magnets used in particle accelerators or for NMR (nuclear magnetic resonance), we often envision bulky machines, sometimes the size of buildings. But in an extraordinary breakthrough for physics, scientists at ETH Zurich have created magnets that are small enough to fit in the palm of your hand yet powerful enough to rival some of the world’s most powerful magnets.

Breakthrough to Strengthen Bones Could Reverse Osteoporosis

Research points to a key bone-strengthening mechanism at work in the body, which could be targeted to treat the bone-weakening disease, osteoporosis.

Led by scientists from the University of Leipzig in Germany and Shandong University in China, the 2025 study identified the cell receptor GPR133 (also known as ADGRD1) as being crucial to bone density, via bone-building cells called osteoblasts.

Variations in the GPR133 gene had previously been linked to bone density, leading researchers to turn their attention to the protein it encoded.

Strontium optical clock accurate to within 1 second over 30 billion years

Researchers from the University of Science and Technology of China have achieved a major breakthrough in optical clock technology, developing a strontium optical lattice clock with stability and uncertainty both surpassing the 10⁻¹⁹ level, meaning the clock would lose or gain less than one second over roughly 30 billion years.

The findings are published in the journal Metrologia.

Optical clocks are considered the most precise timekeeping devices currently available. They measure time by using the frequency of light emitted when electrons transition between energy levels in atoms.

Flexible high-density microelectrode arrays for closed-loop brain–machine interfaces: a review

Flexible high-density microelectrode arrays (HDMEAs) are emerging as a key component in closed-loop brain–machine interfaces (BMIs), providing high-resolution functionality for recording, stimulation, or both. The flexibility of these arrays provides advantages over rigid ones, such as reduced mismatch between interface and tissue, resilience to micromotion, and sustained long-term performance. This review summarizes the recent developments and applications of flexible HDMEAs in closed-loop BMI systems. It delves into the various challenges encountered in the development of ideal flexible HDMEAs for closed-loop BMI systems and highlights the latest methodologies and breakthroughs to address these challenges. These insights could be instrumental in guiding the creation of future generations of flexible HDMEAs, specifically tailored for use in closed-loop BMIs.
