Over the years, scientists have used 3D printers for various products. They include electronic devices, jewelry and even artificial organs. Now, mechanical engineers from New York's Columbia University have unveiled a 3D-printed cheesecake made with seven ingredients. This is the most number of items ever used to print a single food product....

This year's eclipse season will begin with a bang with a hybrid solar eclipse on April 20, 2023. The rare astronomical event occurs just once every decade. The last one was on November 3, 2013, and the next one will not be until November 30, 2031. Unfortunately, the celestial phenomenon will only be seen in western Australia, East Timor, and eastern Indonesia....

An international team of researchers has found the fossilized remains of the largest-known penguin on Earth. The newfound species is thought to have weighed about 340 pounds (154 kg). This is over three times heavier than the largest living species, the emperor penguin. The record previously belonged to a 256-pound (116 kg) penguin that lived in Antarctica about 37 million years ago....

The fruit fly larva is no more than 10 mm long. Hence, it would be reasonable to assume that its brain, which is smaller than a poppy seed, is fairly simple. However, a recently-unveiled map of the insect's brain shows a surprisingly complex structure. It has 3,016 neurons connected by 548,000 synapses....

Dr. Joseph Dituri is on a mission to spend 100 days underwater. If successful, the University of South Florida (USF) associate professor will set a new record for undersea living. The record is a nice bonus. But the researcher is mainly doing it for science....

The recent discovery of the oldest-known vertebrate brain is giving scientists valuable insights into the evolution of the ray-finned fish species. The diverse group comprises about 50 percent of living vertebrate species. They include everything from trout to salmon and goldfish to seahorses....

A holiday celebrating a math constant may not seem very exciting. But Pi ("π") Day, observed annually in the US on March 14 (3/14), is an exception. The celebrations usually start with math activities centered around pi — the ratio of the circumference of a circle to its diameter — widely recognized as 3.14. But they typically end with a slice or two of delicious pie!...

Malaria is a life-threatening disease caused by parasites. It is transmitted to humans through the bites of infected female mosquitoes. Malaria can be found in most tropical and subtropical climates. But Africa is the most affected for a number of reasons. In 2021, 619,000 people died of malaria worldwide. Most were young children in sub-Saharan Africa. However, there is hope. Two recently-approved vaccines may provide some protection against this deadly disease....

The health impacts of outdoor air pollution are well-known. But indoor air pollution, caused by emissions from building materials or even air fresheners, can be just as harmful. Yet, there are no widely-accepted methods to detect the toxins. But researchers at the University of Turku in Finland hope to change that with the help of tiny glowing worms....
