Unknown submarine landslides discovered in Gulf of Mexico

A researcher has used new detection methods to identify 85 previously unknown submarine landslides that occurred in the Gulf of Mexico between 2008 and 2015, leading to questions about the stability of oil rigs and other structures, such as pipelines built in the region.

New study estimates the odds of life and intelligence emerging beyond our planet

Humans have been wondering whether we alone in the universe since antiquity. We know from the geological record that life started relatively quickly, as soon our planet's environment was stable enough to support it. We also know that the first multicellular organism, which eventually produced today's technological civilization, took far longer to evolve, approximately 4 billion years.

Brain-to-gut connections traced

Using rabies virus injected into the stomach of rats, researchers trace the nerves back to the brain and find distinct 'fight or flight' and 'rest and digest' circuits. These results explain how mental states can affect the gut, and present new ways to treat gastrointestinal problems.

Exoplanet climate 'decoder' aids search for life

After examining a dozen types of suns and a roster of planet surfaces, astronomers have developed a practical model - an environmental color ''decoder'' - to tease out climate clues for potentially habitable exoplanets in galaxies far away.

First tunable, chip-based 'vortex microlaser' and detector

To break through a looming bandwidth bottleneck, engineers are exploring some of light's harder-to-control properties. Now, two new studies have shown a system that can manipulate and detect one such property: orbital angular momentum. Critically, they are the first to do so on small semiconductor chips and with enough precision that it can be used as a medium for transmitting information.

Scientists find brain center that 'profoundly' shuts down pain

A research team has found a small area of the brain in mice that can profoundly control the animals' sense of pain. Somewhat unexpectedly, this brain center turns pain off, not on. It's located in an area where few people would have thought to look for an anti-pain center, the amygdala, which is often considered the home of negative emotions and responses, like the fight or flight response and...

Even biodiverse coral reefs still vulnerable to climate change and invasive species

A new study reveals clear evidence highlighting the importance of fish biodiversity to the health of spectacular tropical coral reef ecosystems. However, the study's results show that even though strong relationships between diversity and a healthy ecosystem persist, human-driven pressures of warming oceans and invasive species still diminish ecosystems in various ways.

How climate killed corals

A squad of climate-related factors is responsible for the massive Australian coral bleaching event of 2016. If we're counting culprits: it's two by sea, one by land.

Mother roundworms have ultra-protective instincts

Biologists have learned animals can alert future offspring of dangers they will encounter when born. In studies with roundworms and mouse cells, researchers showed how mothers pass chemical signals to their unfertilized eggs, where the warning is stored in the egg cells and passed to offspring after birth.

High five! It's possible to create proximity online

Despite physical distance, it's possible to create proximity between family members located in different places. This is according to a study that has investigated how video calls bring family members together. The results show that proximity in video calls is established mainly by way of the body and the senses, e.g. by giving a digital high five.
