Scientists discover fully regenerating marine animal

Certain amphibians, fish and other sea creatures can grow back missing limbs or damaged organs like brains and hearts. But one species of sea squirt, in particular, takes regeneration to the extreme, growing back entire organs even after being dissected into three separate, organless sections. Researchers from Tel Aviv University in Israel were shocked to discover that the sea squirt species known … Continue reading Scientists discover fully regenerating marine animal

Weak spot in magnetic field may be caused by an ancient planet buried inside the Earth

There is a weak spot in the Earth’s magnetic field, and some scientists believe it may have been caused by the remnants of an ancient planet that impacted the Earth billions of years ago. The Earth has a protective geomagnetic field that shields the planet from deadly solar radiation. This field is generated by a process that … Continue reading Weak spot in magnetic field may be caused by an ancient planet buried inside the Earth

Inspired by spiders and fire ants, researchers develop a new unsinkable metal

Researchers from the University of Rochester have developed an extremely buoyant metal that can be used to make unsinkable ships. The researchers have drawn inspiration from fire ants and diving bell spiders, which have the remarkable ability to remain afloat or survive underwater for long periods of time. These creepy-crawlies are able to do this by trapping air in an … Continue reading Inspired by spiders and fire ants, researchers develop a new unsinkable metal

Study shows cuttlefish can also pass “marshmallow test” designed for children

It’s a well-known fact that dogs and primates are some of the most clever animals on the planet. Dolphins are also known for their intelligence. But according to an interesting study published in the journal Proceedings of the Royal Society B, cephalopods like cuttlefish can give other smart creatures a run for their money. Researchers reported that cuttlefish can also … Continue reading Study shows cuttlefish can also pass “marshmallow test” designed for children

Meteorite in Michigan may hold clues to origin of life on Earth

According to a new study a meteorite that fell in Michigan in 2018 may contain clues to the origin of life on Earth. Published in the journal Meteoritics & Planetary Science, the study said that the meteorite contained a good amount of organic matter. Researchers from the U.S., Canada, Germany and China were able to pick up and examine the rock … Continue reading Meteorite in Michigan may hold clues to origin of life on Earth

Infected patients develop long-term immunity to coronavirus

People infected by the coronavirus develop long-term immunity to COVID-19. A new study published August 14 in the journal Cell presented evidence that the immune system is capable of preventing the recurrence of the disease, thanks to specialized immune cells that commit the virus into memory. Memory T cells are a type of white blood cell trained to recognize … Continue reading Infected patients develop long-term immunity to coronavirus

Scientists develop artificial muscles powered by glucose: Findings will be used to develop a system that’s “even closer to a biological muscle”

A recent breakthrough in engineering and robotics just might blur the line between man and machine. Researchers from Linköping University in Sweden have successfully developed and created artificial muscles that run on glucose and oxygen — just like their organic counterparts. According to the researchers, they wanted to develop artificial muscles, which, instead of using traditional actuators powered by … Continue reading Scientists develop artificial muscles powered by glucose: Findings will be used to develop a system that’s “even closer to a biological muscle”

Updating fluid-powered machines: Scientists design bizarre-looking lionfish powered by a blood-like compound

You’ve heard of robots that can run, lift, jump and crawl. Now, prepare to see one that can bleed. In a paper published in the scientific journal Nature, a joint team of researchers from Cornell University and the University of Pennsylvania detailed how they built a soft robotic lionfish, complete with a multi-functional circulatory system. At its core: a blood-like compound that not … Continue reading Updating fluid-powered machines: Scientists design bizarre-looking lionfish powered by a blood-like compound

Ambitious study looks at converting food waste back into food

Swedish researchers talk about the potential of using fungi to convert food waste into valuable products. In addition to the usual biofuels, animal feed, and textiles produced from waste food, they want to turn the fungi into a protein-rich source of food for humans. Human civilization continues to churn out increasing amounts of waste products like plastic trash and food … Continue reading Ambitious study looks at converting food waste back into food

Worms are cool: They can regrow their brains if they lose their heads

There are some animals that can grow back specific parts of their body when they have been cut off. Lizards, for example, are known for their ability to grow back their tails. However, experts have found something even more fascinating. New research published in Proceedings of the Royal Society B has revealed that some species of ribbon … Continue reading Worms are cool: They can regrow their brains if they lose their heads
