For much of history, many mathematicians—

Following thinkers like Aristotle—viewed infinity as a never-ending process rather than a completed object. In the late 19th century, Georg Cantor revolutionized this view by treating infinite sets as mathematical objects that could be compared and studied. His work showed that not all infinities are equal, and that there are infinitely many different sizes of infinity. While his ideas are foundational in modern mathematics, some philosophical schools, such as finitism and ultrafinitism, continue to question whether infinite objects meaningfully exist.

    Signed software abused to deploy antivirus-killing scripts

    A digitally signed adware tool has deployed payloads running with SYSTEM privileges that disabled antivirus protections on thousands of endpoints, some in the educational, utilities, government, and healthcare sectors.

    In a single day, researchers observed more than 23,500 infected hosts in 124 countries trying to connect to the operator’s infrastructure, with hundreds of infected endpoints present in high-value networks.

    Taking a closer look at immune ‘memory’ could spur progress in the fight against lethal illnesses

    The average human has about 1.8 trillion immune cells. These cells patrol the body for bacteria, viruses, cancers, and other threats. Vaccines enhance this security system by teaching our immune cells to target specific pathogens. According to the World Health Organization, vaccine-induced immunity saves about six lives every minute. But how long does this protective immune “memory” last?

    According to Shane Crotty, Ph.D., Professor and Chief Scientific Officer at La Jolla Institute for Immunology (LJI), we still have much to learn about immune memory.

    “There are actually not many studies of human immune memory due to vaccines,” says Crotty. “Scientists traditionally don’t track immune memory past one year after vaccination—or even six months after vaccination—and that’s a bit of a problem.”

    Math Professor Wrote Wrong Equation on the Board to Test a Black Student—But He Was a Genius Student

    What if creativity wasn’t magic—but math?
    In this video, we explore the mathematics of creativity through psychology, philosophy, and science. From Dean Keith Simonton’s law of large numbers, Margaret Boden’s theory of combinational creativity, Zipf’s Law, Malcolm Gladwell’s 10,000-hour curve, and even cellular automata—we break down how imagination follows hidden equations.

    Whether you’re a student, teacher, scientist, engineer, or philosopher, this video will change how you think about art, science, and human innovation.

    Chapters:
    00:00 – Intro: Is Creativity Random?

    Sofia Kovalevskaya: The Girl Who Wouldn’t Give Up on Math

    “It is impossible to be a mathematician without being a poet in soul.”-Sofia Kovalevskaya

    We don’t often think of math as something that’s “dangerous” or “forbidden”; after all, what could be so dangerous about numbers? Russian-born Sofia Kovalevskaya was told at numerous points during her life that she had to stop studying math, that girls weren’t good enough, they weren’t allowed to go to school, or teach classes, edit magazines or win awards. Sofia Kovalevskaya never gave in to the couldn’t’s or wouldn’t’s. She fought time and again for her right to continue learning and teaching, eventually becoming one of the most celebrated mathematicians of her century and the first woman professor of a northern European University. Today, we celebrate Sofia and all the young mathematicians who overcome great odds!

    When Sofia Kovalevskaya was a little girl in the early 1850’s, her room wasn’t wallpapered with flowers or meadowscapes, it was covered in pages and pages of math lecture not es. She would stare at the pages filled with differential and integral analysis, and while she didn’t understand exactly what she saw, Sofia saw beauty in the calculations.

    Space 18th SDG — A Side Event at COPUOS Legal SubCommittee — 16 April 2026

    Space has become critical infrastructure for climate monitoring, disaster risk reduction, connectivity, navigation, education, and long-term planetary resilience. Even more important, space is an open horizon for new industrial development and settlement, starting with Earth orbit, the geo-lunar system, and the near-Earth asteroids. The Space 18th SDG initiative proposes a non-regulatory, enabling framework that strengthens the existing 17 SDGs by recognizing outer space as both an enabler of sustainable development and an environment requiring stewardship.
    THE PANEL:
    Prof. Sergio Marchisio, Space Law Expert, La Sapienza University, Rome, Italy.
    Ms. Fikiswa Majola, Deputy Director Space Systems, Department of Science and Technology (DST) South Africa.
    Prof. Guoyu Wang — Space Law Center, China National Space Administration.
    Dr. Claire Nelson, The Future Forum, Giamaica.

    Specific Gravity Made Easy | Float, Sink & Hydrometer Explained

    In this Easy Peasy Chemistry lesson, we break down Specific Gravity in a simple and clear way!

    After learning about density, it’s time to understand how substances compare to water. Why do some objects float while others sink? What does a hydrometer reading like 1.25 actually mean?

    In this video, you’ll learn:

    • What specific gravity really means
    • How it is different from density
    • Why water is used as the reference
    • How floating and sinking are related
    • How a hydrometer measures specific gravity
    • Why specific gravity has no units.

    This lesson is perfect for high school, college, pre-med, nursing, and engineering students.

    Watch till the end to fully understand how scientists measure and compare densities in the lab.

    A greener route to citrus-derived therapeutics: What a new bromination method changes

    Undergraduate students at Penn State Brandywine developed an environmentally friendly and easy method to synthesize compounds from plant-derived molecules for potential use in therapeutics. Their work, conducted under the supervision of Penn State Brandywine Assistant Professor of Chemistry Anna Sigmon, was published in a special issue of the journal ACS Omega titled “Undergraduate Research as the Stimulus for Scientific Progress in the U.S.”

    Co-author Maria Englert, who graduated from Penn State in 2025, became involved with Sigmon’s research on the recommendation of another mentor and said she learned far more than she expected.

    “The more we worked through the reactions and discussed methodologies with each other, the more chemistry felt like an art form—something that requires creativity, intuition and a tenacious approach to problem-solving,” she said. “This experience taught me that progress in research is shaped by collaboration, careful observation and a willingness to rethink your approach.”

    Artemis II kisses the Moon! — Space Renaissance with Artemis 2 on lunar farside!

    This is the preliminary webinar #16 of the IV SRI World Congress (SRIC4)
    Abstract:
    The expansion of the commercial spaceflight sector and democratization of space is creating new opportunities for artists to engage directly with the environment of space. For a new generation of space artists, space presents new physical and philosophic questions. This webinar explores how space artists are redefining their practice through direct engagement with space, using case-studies of work that has been deployed on board the ISS, sub-orbital flights, and zeroG flights. Through these, the webinar will explore how artists are revising traditional art methods and materials through interactions with microgravity; the relationships between artists, astronauts and audiences; and the disciplinary and hierarchy challenges faced by artists operating in the space sector.

    An essential Bio:
    Dr Barbara Brownie is an Associate Dean (Education) at the Royal College of Art. Barbara’s research explores space as a site for art and design, with a particular focus on effects of weightlessness. Her book, Spacewear: Weightlessness and the Final Frontier of Fashion (Bloomsbury, 2019), considers the challenges and opportunities that the commercial space age presents to fashion designers, and how weightlessness necessitates new approaches to clothing and the dressed body. Her most recent book, Art in Orbit (Bloomsbury 2025), explores the relationship between the arts and space sectors, and the spaceworks that demonstrate art’s value in space exploration. In 2026 and 2027 she will be sending writing and artworks to space on three separate flights: one sub-orbital, one orbital, and one lunar. She co-leads the _Space research group at the RCA, a group of artists and researchers operating at the intersection of art and aerospace.
