What Your Body Odor Says About You
When Annlyse Retiveau leaned in to sniff my armpits, I held my own breath as she inhaled. I’ve spent a vast majority of my life using products to avoid this precise critique—another human intentionally evaluating my armpit aroma. Yet, whether we like it or not, humans do smell each other, and we can glean useful social cues and health information from the body odor of others, albeit...
Perseverance Mars Rover to acquire first sample
NASA is making final preparations for its Perseverance Mars rover to collect its first-ever sample of Martian rock, which future planned missions will transport to Earth. The six-wheeled geologist is searching for a scientifically interesting target in a part of Jezero Crater called the "Cratered Floor Fractured Rough."
Wildfires in US West blowing 'so much smoke' into East Coast
Smoke and ash from massive wildfires in the American West shrouded the sky and led to air quality alerts on parts of the East Coast on Wednesday as the effects of the blazes were felt 2,500 miles (4,023 kilometers) away.
New algorithm flies drones faster than human racing pilots can
- ScienceDaily
- 21/7/21 20:20
For the first time an autonomously flying quadrotor has outperformed two human pilots in a drone race. The success is based on a novel algorithm that calculates time-optimal trajectories that fully consider the drones' limitations.
Lifting advice doesn't stand up for everyone, study finds
- ScienceDaily
- 21/7/21 20:20
Commonly accepted advice to keep a straight back and squat while lifting in order to avoid back pain has been challenged by new research. The research examined people who had regularly performed manual lifting through their occupation for more than five years and found those who experienced low back pain as a result were more likely to use the recommended technique of squatting and keeping a...

Kids eat more fruit and vegetables with longer seated lunch time
- ScienceDaily
- 21/7/21 20:19
When kids sit down to eat lunch at school, fruits and vegetables may not be their first choice. But with more time at the lunch table, they are more likely to pick up those healthy foods. If we want to improve children's nutrition and health, ensuring longer school lunch breaks can help achieve those goals, according to new research.
