NASA is seeking suggestions from the public for a message to beam far, far out into space to the probe Voyager 1 in time for the 40th anniversary of its launch.

Op-Ed: Women continue to be underrepresented in STEM fields

Despite government campaigns women remain underrepresented in science and technology. Despite what an infamous ex-Google employee wrote, this is nothing innate. The low levels reflect institutional and societal biases.

Flooding and storm extremes to increase with global warming

Researchers at the University of New South Wales, Australia, have done an exhaustive global analysis that shows signs of a radical shift in stream-flow patterns, with more intense flooding in cities along with drier countrysides.

Essential Science: First genome-wide cancer map produced

An interesting new map shows over 760 genetic dependencies across multiple cancers. The map suggests new opportunities for developing innovative cancer treatments for scientists and start-up biotech.

Screening for novel drugs using powerful computers

Searching for new types of drugs is a medical imperative. This is a complex task involving many types of diseases and chemical interactions. To assist with this process, Francis Crick Institute researchers have developed a new model.

Can artificial intelligence aid human age-reversal?

Combating the human aging process, either for health reasons or reasons more attuned to simply living for longer, has occupied considerable amounts of scientific inquiry. The solution to combating cell aging may lie with artificial intelligence.

It's now possible to hack a computer using DNA

As University of Washington laboratory uses strands of DNA to hack into a computer. What does this mean for companies developing DNA data storage solutions?

Scientists gene-edit piglets, bringing transplants to humans closer

Scientists have successfully edited the genetic code of piglets to remove dormant viral infections, a breakthrough that could eventually pave the way for animal-to-human organ transplants.
