Algorithm can reliably predict alcohol consumption and sobriety. (AP Photo/Rick Bowmer)Researchers have created an algorithm that correctly predicts drinking and sobriety among individuals experiencing homelessness four out of five times, using it to develop a smartphone app that delivers personalized intervention messages to people at risk of alcohol misuse.

Sea spray can carry algal toxins into the air. (Emmanuel van Acker)Toxins released by algae and launched into the air by bursting bubbles and breaking waves can accumulate to much higher levels than are found in seawater, and can then be inhaled and potentially impact human health.

Bioluminescence is beautiful at the beach, and now it'll help detect buried explosives.
Bioluminescence is beautiful at the beach, and now it'll help detect buried explosives.Researchers at the Hebrew University of Jerusalem have developed a sensor that can rapidly locate buried explosives with the help of genetically engineered, bioluminescent E. coli bacteria, allowing field workers to search for dangerous buried ordnance from afar.

Humans are even worse for Australian ash forests than wildfires. (Unsplash/Neroli Wesley)By reconstructing the history of Australia's ash tree forests, researchers revealed that human disturbances from logging and post-fire salvage have more negative effects on the health of the ecosystem than natural disturbances from increasingly common wildfires.

A new protein-folding machine might dramatically curb food waste. (AP Photo/Steven Groves)A new computational model combines artificial intelligence with biology to design and fold proteins in a method that could yield specialized proteins for different applications, such as an edible coating for crops that reduces food waste.

Less than a quarter of adolescents meet targets for recovery after treatment for depression. (Unsplash/Francisco Gonzalez)Most teenagers with anxiety or depression do not show meaningful change across the categories of symptoms, daily function and goals after treatment, according to new research from University College London and the Wellcome Trust.

South American hydropower is in danger from dropping rainfall amounts. (AP Photo/Nicholas K. Geranios)As rainfall over tropical and semiarid parts of South America declines due to climate change, streamflow will ebb in river basins that are vital for generating hydroelectric power and lead to water scarcity later this century, scientists say.

Having a woman at the top of the org chart helps keep companies out of court. (AP Photo/Pat Sullivan)Companies led by female chief executives encounter fewer serious allegations of coercive labor practices and face fewer labor lawsuits than firms led by men, according to a new study that is among the first to look at the relationship between gender diversity in corporate leadership and day-to-day employee welfare.

Cold ocean waters do most of the job of heat absorption in the Earth's ocean system. (Devin Powell/NOAA via AP)
Cold ocean waters do most of the job of heat absorption in the Earth's ocean system. (Devin Powell/NOAA via AP)As the world's oceans bear most of the warming burden created by climate change, a study found that half of all added heat from the last 44 years entered through the coldest one-quarter of surfaces, according to a newly debuted framework that sorts oceanic regions by temperature.

If this picture makes you itchy, a new sensor can track when you scratch. (Pixabay/WikiImages)
If this picture makes you itchy, a new sensor can track when you scratch. (Pixabay/WikiImages)Scientists have devised a more objective way of measuring itch with a wearable sensing technology that tracks how often people scratch themselves and accurately distinguishes real scratching from similar motions, potentially giving physicians better information to help patients with eczema and other itch-related conditions find relief.

Does Bach make you want a burger? Tchaikovsky for tofu? Music can influence our food choices. (AP Photo/Nati Harnik)
Does Bach make you want a burger? Tchaikovsky for tofu? Music can influence our food choices. (AP Photo/Nati Harnik)Research in China and Denmark has revealed that, across cultures, certain types of music can cause people to spend more time fixating on healthy foods than on unhealthy alternatives, suggesting healthy eating habits could be promoted through the use of sound.

We're starting to count the economic cost of the pandemic. (AP Photo/Emilio Espejel)An inevitable trade-off exists between an epidemic's health consequences and its corresponding economic impacts, new research concludes, with the optimal containment strategy prioritizing lives and accepting a short-term recession in order to achieve a faster recovery in the years ahead.

A new automated system might help track kids' speech development. (AP Photo/Danny Johnston)Children struggling with speech development currently rely on in-person evaluation sessions with speech-language pathologists to track progress and identify impairments, but U.S. researchers have invented a more efficient, automated method of monitoring speech through digital platforms based on a new machine-learning algorithm.

New evidence as to how demographics factor into suicide rates could improve prevention efforts. (Unsplash/Mariah Solomon)There are significant differences in U.S. suicide death rates and methods across age, race and sex — and younger generations of people of color, particularly Black people, are becoming more likely to die by nonfirearm suicide, a finding that researchers say has implications for mental health interventions and emergency counseling.

Iron meteorites might have delivered some of the building blocks for life to early Earth. (Jamie Elsila)
Iron meteorites might have delivered some of the building blocks for life to early Earth. (Jamie Elsila)A type of meteorite made mostly of iron can contain small amounts of amino acids, suggesting that the rocks could have been a source of the organic molecules for the early Earth and perhaps provided some of the ingredients from which life originated.

A new transistor gets computers closer to thinking like humans. (Northwestern University)Researchers from Northwestern University and the University of Hong Kong have created an electrochemical transistor that mimics brain synapse functions to form a circuit made of soft plastic, ultimately producing a novel device capable of learning by association in much the same way as our brains.

Genetic ancestry is important in assessing disease risk, but it's important to steer clear of racism. (Unsplash/Laura Furhman)Considering race and ethnic background when assessing disease burden is believed to walk a fine line between informed care and systemic racism, but arguing that heritage can weigh heavily on one's propensity for illness, researchers are advocating for a refined way of incorporating genetic ancestry without teetering toward the side of prejudice.

It's going to take societal change to cut down on restaurant food waste. (Unsplash/Alexander Schimmeck)Subtle behavioral nudges aimed at diners can significantly reduce restaurant food waste, even in countries where packaging leftovers for future consumption is attached to financial-centered shame or other social stigmas, new research suggests.
