In a cross-sectional study of adults aged 25–49 years in the US, colorectal cancer (CRC) mortality rose from 1994 to 2023, primarily among those with 15 or fewer years of education, and educational disparities in mortality widened over time. More on the study.
Researchers analyze trends in colorectal cancer mortality among adults aged 25–49 years in a study spanning about three decades.
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.

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.
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.”
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.

“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 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. Adriano V. Autino, SRI CEO & Founder. Maria Antonietta Perino, Thales Alenia Space, Italy. Stefano Antonetti, D-ORBIT SpA, Strategy Director, Italy. Antonio Stark, iSpace, Japan. MODERATES: Dr. Gülin Dede, SRI Director of Relations, Chair of the Space 18th SDG Coalition.
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.
MIT’s Department of Mechanical Engineering (MechE) offers a world-class education that combines thorough analysis with hands-on discovery. One of the original six courses offered when MIT was founded, MechE faculty and students conduct research that pushes boundaries and provides creative solutions for the world’s problems.
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.”
