Is your kid obsessed with video games and hanging out with questionable friends? These are common traits for involvement in cybercrime, among other delinquencies. New research from Michigan State University identified characteristics and gender-specific behaviors in kids that could lead them to become juvenile hackers.

The journal Science has published a letter titled "Solve the biodiversity crisis with funding," coauthored by scientists at Defenders of Wildlife and universities across the country. More than 1,600 scientists have so far endorsed the letter, calling on Congress to fully fund conservation programs that protect biodiversity from severe and growing threats.

Quantum mechanics and the general theory of relativity form the bedrock of the current understanding of physics—yet the two theories don't seem to work together. Physical phenomena rely on relationship of motion between the observed and the observer. Certain rules hold true across types of observed objects and those observing, but those rules tend to break down at the quantum level, where subatomic particles behave in strange ways.

An international team of researchers led by scientists at Princeton University has found that a magnetic material at room temperature enables electrons to behave counterintuitively, acting collectively rather than as individuals. Their collective behavior mimics massless particles and anti-particles that coexist in an unexpected way and together form an exotic loop-like structure.

A study published today in the journal Science reveals that since 1970, bird populations in the United States and Canada have declined by 29 percent, or almost 3 billion birds, signaling a widespread ecological crisis. The results show tremendous losses across diverse groups of birds and habitats—from iconic songsters such as meadowlarks to long-distance migrants such as swallows and backyard birds including sparrows.

College-student voting rates in the 2018 midterm elections doubled compared to the 2014 midterms, marking a watershed election year for student voter turnout, according to a report today from the Institute for Democracy & Higher Education (IDHE) at Tufts University's Tisch College of Civic Life. The report, Democracy Counts 2018, is based on an analysis of the voting patterns of more than 10 million college students on more than 1,000 campuses participating in the National Study of Learning, Voting, and Engagement (NSLVE).

Cells consist of a multitude of molecular structures, some of them exhibiting a staggering complexity. Ribosomes, the protein factories of the cell, belong to the biggest and most sophisticated complexes and are made up of RNA as well as a large number of proteins. They exist in every living being and are considered as one of the cellular machines that has changed the least through all stages of the evolution. But there are exceptions: In mitochondria, cellular organelles that serve as power plants, ribosomes look considerably different.
