Repeats of DNA sequences, often referred to as “junk DNA” or “dark matter,” that are found in chromosomes and could contribute to cancer or other diseases have been challenging to identify and characterize. Now, investigators at the Johns Hopkins Kimmel Cancer Center have developed a novel approach that uses machine learning to identify these elements in cancerous tissue, as well as in cell-free DNA (cfDNA) — fragments that are shed from tumors and float in the bloodstream. This new method could provide a noninvasive means of detecting cancers or monitoring response to therapy. Machine learning is a type of artificial intelligence that uses data and computer algorithms to perform complex tasks and accelerate research.

For telescopes operating in the vacuum of space, or optical equipment in extreme environments, existing coatings are often insufficient. In the Journal of Vacuum Science & Technology Aresearchers in China turned to atomic layer deposition and developed an ultrablack thin-film coating for aerospace-grade magnesium alloys. The team used alternating layers of aluminum-doped titanium carbide and silicon nitride and together the materials prevent nearly all light from reflecting off the coated surface. The coating absorbs 99.3% of light while being durable enough to survive in harsh conditions.

The best measurements from Hubble show the universe is now expanding faster than predicted based on observations of how it looked shortly after the big bang. Some scientists suggested that Hubble observations are wrong due to some creeping inaccuracy in its deep-space yardstick. However, Webb’s sharp infrared views of milepost markers known as Cepheids agree with Hubble data.
Taking “study drugs” like Adderall without a diagnosis is not only dangerous in itself, but can lead to other drug use and a decline in mental health, according to new research from Binghamton University, State University of New York.
In the astronomy field, the term “nearby” is quite relative. Neighboring galaxies to our home galaxy, the Milky Way, are a few million light-years away. In contrast, some of the most distant galaxies ever detected, closer to the Big Bang, are billions of light-years away.

In a new study from the University of Georgia, researchers found that the time high schoolers spend on so-called enrichment activities—including tutoring, sports, school clubs and even homework—is negatively affecting their mental health. The study also found that any additional enrichment activities are unlikely to benefit students academically. While the ideal number of study hours will vary student by student, researchers found that adding more enrichment activities is unlikely to benefit students. Many people think additional study time or tutoring will lead to better test scores and grades, but this research shows that students are already at their limit. Any more “enrichment” will have negative returns.
