Andrea Estefanía Portales is a freelance science writer based in Argentina who also works as a graduated teaching assistant in biochemistry at the Faculty of Exact Sciences of La Plata National University (UNLP).
Before exploring the science communication field, she obtained a Ph.D. in biology from UNLP, studying the mechanisms that regulate the appearance of energy-dissipating fat cells in white fat. Besides translating the hard science into edible content, she enjoys playing all kinds of sports.
A chlorophyll sensor detects plant stress for better crop yields
The sensor could improve crop yield by detecting changes in plant chlorophyll levels earlier and more precisely than existing methods.
Have your morning coffee and wear it too!
Scientists convert waste coffee husks into cellulose fibers and films with potential applications in textiles and biodegradable products.
A pocket-sized PCR test delivers results in 15 minutes
The hand-held device was designed for use by the general public, providing diagnoses in only 15 minutes without the need for appointments and long wait times for results.
A new, simple test enables early detection of ovarian cancer
Scientists are hopeful that a new, more sensitive test for detecting ovarian cancer might provide better options, especially for patients with BRCA genes.
Predicting wound healing with a wound-integrated miniaturized sensor
Scientists develop a sensor that predicts wound healing rate with more than 70% accuracy.
A smart package for monitoring food contamination
A new device can detect Salmonella on individual products in real-time and with minimal need for laboratory equipment or specialized operators.
Thin film improves “usable light” needed to grow microalgae on industrial scales
A textured film maximizes sunlight by generating an increased amount of red light, reducing the costs of algae production on a significant scale.
A long-lasting drug delivery system to treat HIV
This clever drug delivery platform could improve HIV patients’ adherence to treatment and help eradicate the virus.
Low-cost contact lenses to tackle color blindness
Scientists used 3D printing and an inexpensive ink to make colored contact lenses that could improve color distinction in color-blind people.
