Engineers identified an optical signature in a widely used class of magnetic 'Dynabeads' that could be used to quickly detect contaminants in food, water, or the human body.
Scientists invent new way to sort cells by type using light
Researchers have developed and demonstrated a new method for high-throughput single-cell sorting that uses stimulated Raman spectroscopy rather than the traditional approach of fluorescence-activated cell sorting. The new approach could offer a label-free, nondestructive way to sort cells for a variety of applications, including microbiology, cancer detection and cell therapy.
Paper cups are just as toxic as plastic cups
Replacing single use plastic cups with paper ones is problematic. Researchers show that a paper cup that ends up in nature can also cause damage as they also contain toxic chemicals.
Paper drinking straws may be harmful and may not be better for the environment than plastic versions
'Eco-friendly' paper drinking straws contain long-lasting and potentially toxic chemicals, a new study has concluded.
2023 Global Heat Wave: July brought the hottest three weeks observed so far
The first three weeks of July 2023 have been the hottest global three-week period so far. Researchers report that the European population's exposure to heat was highest in Italy.
Bonobos grow similarly to humans
Parents with children in adolescence know this all too well: one minute 'the little ones' are just up to your shoulder, and all of a sudden, they're growing over your head. Until now, it was assumed that such pubertal growth spurt in body length only occurs in humans, but not...
Loss of Antarctic sea ice causes catastrophic breeding failure for emperor penguins
Emperor penguin colonies experienced unprecedented breeding failure in a region of Antarctica where there was total sea ice loss in 2022. The discovery supports predictions that over 90% of emperor penguin colonies will be quasi-extinct by the end of the century, based on current global warming trends.
New modeling method helps to explain extreme heat waves
To prepare for extreme heat waves around the world -- particularly in places known for cool summers -- climate-simulation models that include a new computing concept may save tens of thousands of lives.
Scientists solve mystery of why thousands of octopus migrate to deep-sea thermal springs
Researchers used advanced technology to study a massive aggregation of deep-sea octopus gathered at thermal springs near an extinct underwater volcano off the coast of Central California. Warm water from hydrothermal springs accelerates development of octopus embryos, giving young octopus a better chance of survival. The Octopus Garden is the...
National parks support wildlife inside and outside their borders
Fresh research suggests that national parks enhance bird diversity inside their borders. Large parks also support higher diversity of both birds and mammals in nearby unprotected areas.
