A new material designed to harvest up to 400 times more energy from movement than currently possible has potential applications in biomedicine and geospatial monitoring.

Researchers at Eötvös Loránd University have investigated whether the perception of time changes with age, and if so, how, and why we perceive the passage of time differently. Their study was published in Scientific Reports.
Time can play tricks on us. Many of us experienced the illusion that those long summers during childhood felt so much longer than the same 3 months feel like now as an adult. While we can argue why one summer may appear longer than the other and how the perception of time can compress and dilate durations depending on various factors, we can easily set up an experiment to gain more insights.
The researchers just did that. They asked how eventfulness affects our duration estimates when probing at different milestones during our cognitive development. They set aside three age groups, 4–5, 9–10, and 18 years and older, and made them watch two videos, 1 minute each. The two videos were extracted from a popular animated series, balanced in visual and acoustic features, except for one feature: eventfulness.
A study from researchers at The University of Texas MD Anderson Cancer Center, published today in Nature Cell Biology, details a previously unexplained type of cell death called disulfidptosis that could open the door for novel cancer therapeutic strategies.
As described in the study, disulfidptosis is triggered when cells with high levels of the SLC7A11 protein are subjected to glucose starvation. In preclinical models, treatment with glucose inhibitors induced disulfidptosis in cancer cells with high SLC7A11 expression, effectively suppressing tumor growth without significant toxicity in normal tissues.
The study was led by Boyi Gan, Ph.D., and Junjie Chen, Ph.D., both professors of Experimental Radiation Oncology.

The emerging quantum technology industry offers a dynamic career pathway for creative and adaptable physical scientists, as Stuart Woods of Oxford Instruments NanoScience explains.
As quantum technology companies shift gears to translate their applied research endeavours into commercial opportunities – at scale – they’re going to need ready access to a skilled and diverse quantum workforce of “all the talents”. A case study in this regard is Oxford Instruments NanoScience, a division of parent group Oxford Instruments, the long-established UK provider of specialist technologies and services to research and industry.
The NanoScience business unit, for its part, designs and manufactures research tools to support the development, scale-up and commercialization of next-generation quantum technologies. Think cryogenic systems (operating at temperatures as low as 5 mK) and high-performance magnets that enable researchers to harness the exotic properties of quantum mechanics – entanglement, tunnelling, superposition and the like – to yield practical applications in quantum computing, quantum communications, quantum metrology and quantum imaging.
Most biologists will answer confidently when asked ‘which came first, the chicken or the egg? but the answer may depend on what type of egg you’re talking about.
The viruses Kaposi sarcoma-associated herpesvirus (KSHV) and Epstein-Barr virus (EBV) have been linked to several cancers. For the first time, UNC School of Medicine scientists have discovered that these viruses use a human protein called barrier-to-autointegration factor 1, or BAF, to evade our innate immune response, allowing the viruses to spread and cause disease.
These findings, published in Nature Communications, suggest that BAF and related proteins could be therapeutic targets to prevent these viruses from spreading and leading to cancers, such as Kaposi sarcoma, non-Hodgkin lymphoma, Hodgkin lymphoma, multicentric Castleman disease, nasopharyngeal carcinoma, and gastric cancer.
“Viruses are in a constant battle with the cellular immune system, which includes the protein cyclic GMP-AMP synthase, or cGAS, which binds to viral DNA and sounds the alarm to trigger immune responses and fight the viral invaders,” said senior author Blossom Damania, Ph.D., the Boshamer Distinguished Professor of Microbiology and Immunology and member of the Lineberger Comprehensive Cancer Center. “We’ve discovered that KSHV and EBV use a different host cell protein, BAF, to prevent cGAS from sounding the alarm.”
Summary: Using advanced neuroimaging techniques, researchers discovered distant brain regions oscillate together in time.

It’s been over 20 years since neuroimaging studies – using functional magnetic resonance imaging (fMRI), a widely-used technology to capture live videos of brain activity – have been detecting brain-wide complex patterns of correlated brain activity that appear disrupted in a wide range of neurological and psychiatric disorders.
It seems more companies will be using AI to write their articles and other content. 😀
Over the holidays, while most media executives were perhaps looking to get a reprieve from work, Jonah Peretti was online, fully immersed in experimenting with artificial intelligence.
NEW YORK (AP) — A major 7.8 magnitude earthquake followed by another strong quake devastated wide swaths of Turkey and Syria Monday, killing thousands of people.
