Lessons from ‘Star Trek: Picard’ – a cybersecurity expert explains how a sci-fi series illuminates today’s threats

‘Star Trek: Picard’ is set 400 years in the future, but, like most science fiction, it deals with issues in the here and now. The show’s third and final season provides a lens on cybersecurity.
New research shows that the destructive merging of a star and a planet expels huge amounts of gas, as shown in this artist’s impression. K. Miller/R. Hurt (Caltech/IPAC)

Astronomers just saw a star eat a planet – an astrophysicist on the team explains the first-of-its-kind discovery

Stars begin to expand when they run out of fuel and can become thousands of times larger, consuming any planets in the way. For the first time, astronomers have witnessed one such event.

Memories may be stored in the membranes of your neurons

Pinpointing where memories are stored in the brain and how they are transmitted could provide new targets to treat neurological diseases and serve as models for neuromorphic computing.

Debunking the Dunning-Kruger effect – the least skilled people know how much they don’t know, but everyone thinks they are better than average

The idea that the least skilled are the most unaware of their incompetency is pervasive in science and pop culture. But a new analysis of the data shows that the Dunning-Kruger effect may not be true.
Gain-of-function experiments in the lab can help researchers get ahead of viruses naturally gaining the ability to infect people in the wild. KTSDesign/Science Photo Library via Getty Images

Gain-of-function research is more than just tweaking risky viruses – it’s a routine and essential tool in all biology research

From cancer immunotherapy and antibiotics to GMO crops and pandemic surveillance, gain of function is a cornerstone of basic research.

Reconstructing ancient bacterial genomes can revive previously unknown molecules – offering a potential source for new antibiotics

Ancient microbes likely produced natural products their descendants today do not. Tapping into this lost chemical diversity could offer a potential source of new drugs.

Cloud seeding can increase rain and snow, and new techniques may make it a lot more effective – podcast

Cloud seeding – spraying materials into clouds to increase precipitation – has been around for nearly 80 years. But only recently have scientists been able to measure how effective it really is.

Enigmatic human fossil jawbone may be evidence of an early Homo sapiens presence in Europe – and adds mystery about who those humans were

Scientists had figured a fossil found in Spain more than a century ago was from a Neandertal. But a new analysis suggests it could be from a lost lineage of our species, Homo sapiens.

What causes volcanoes to erupt?

As they shape the Earth, volcanoes inspire and terrify humans.
Most tumors are made up of many different kinds of cancer cells, as shown in this pancreatic cancer sample from a mouse. Ravikanth Maddipati/Abramson Cancer Center at the University of Pennsylvania via National Cancer Institute

Every cancer is unique – why different cancers require different treatments, and how evolution drives drug resistance

There is no one-size-fits-all approach to treating cancer. Understanding how cancer cells evolve could help researchers develop more effective drugs.

‘Got polio?’ messaging underscores a vaccine campaign’s success but creates false sense of security as memories of the disease fade in US

Polio vaccines have been a massive public health victory in the US. But purely celebratory messaging overlooks the ongoing threat if vaccination rates fall.

Cognitive flexibility is essential to navigating a changing world – new research in mice shows how your brain learns new rules

Learning new rules requires the suppression of old ones. A better understanding of the brain circuits involved in behavioral adaptation could lead to new ways to treat schizophrenia and bipolar disorder.

Leprosy-causing bacteria found in armadillo specimens highlight value of museum collections for tracking pathogens

Museum archives hold biological specimens that have been collected over years or even decades. Modern molecular analysis of these collections can reveal information about pathogens and their spread.
