New research shows that the brain’s slow oscillations and sleep spindles — key rhythms that consolidate memories during sleep — can be shaped by more than just age.

Goodbye plastic? Scientists create new supermaterial that outperforms metals and glass
Scientists at Rice University and University of Houston have developed an innovative, scalable approach to engineer bacterial cellulose into high-strength, multifunctional materials. The study, published in Nature Communications, introduces a dynamic biosynthesis technique that aligns bacterial cellulose fibers in real-time, resulting in robust biopolymer sheets with exceptional mechanical properties.
Plastic pollution persists because traditional synthetic polymers degrade into microplastics, releasing harmful chemicals like bisphenol A (BPA), phthalates and carcinogens. Seeking sustainable alternatives, the research team led by Muhammad Maksud Rahman, assistant professor of mechanical and aerospace engineering at the University of Houston and adjunct assistant professor of materials science and nanoengineering at Rice, leveraged bacterial cellulose — one of Earth’s most abundant and pure biopolymers — as a biodegradable alternative.
Chicago’s $1 Billion Quantum Computer to Start Operating in 2028
The startup behind Chicago’s more than $1 billion quantum computing deal said operations are expected to start in three years, a win for Illinois Governor JB Pritzker, who backed the investment and is widely seen as a potential presidential candidate.
PsiQuantum Corp. will start construction at the state’s new quantum and microelectronics park in the South Side of Chicago later this year, Chief Executive Officer Jeremy O’Brien said in an interview at Bloomberg’s Chicago office. The supercomputer — one of two utility-scale, fault-tolerant machines the company is building globally — is expected to be online in 2028, he said.
The dawn of quantum advantage
Quantum computing is about to enter an important stage — the era of quantum advantage. The first claims of quantum advantage are emerging, and over the next few years, we expect researchers and developers to continue presenting compelling hypotheses for quantum advantages. In turn, the broader community will either disprove these hypotheses with cutting-edge techniques — or the advantage holds.
Put simply, quantum advantage means that a quantum computer can run a computation more accurately, cheaply, or efficiently than a classical computer. Between now and the end of 2026, we predict that the quantum community will have uncovered the first quantum advantages. But there’s more to it than that.
We have arrived already at a place where quantum computing is a useful scientific tool capable of performing computations that even the best exact classical algorithms can’t. We and our partners are already conducting a range of experiments on quantum computers that are competitive with the leading classical approximation methods. At the same time, computing researchers are testing advantage claims with innovative new classical approaches.

MethAgingDB: a comprehensive DNA methylation database for aging biology
Scientific Data — MethAgingDB: a comprehensive DNA methylation database for aging biology. MethAgingDB includes 93 datasets, with 11,474 profiles from 13 distinct human tissues and 1,361 profiles from 9 distinct mouse tissues. The database provides preprocessed DNA methylation data in a consistent matrix format, along with tissue-specific DMSs and DMRs, gene-centric aging insights, and an extensive collection of epigenetic clocks. Together, MethAgingDB is expected to streamline aging-related epigenetic research and support the development of robust, biologically informed aging biomarkers.
