Interplanetary hoppers: Microbes from Earth may have reached Venus by hitchhiking on asteroids
If Venusian life does exist, it may have originated from Earth: An interplanetary hopper hitched a ride with an asteroid that grazed Earth’s upper atmosphere and landed on Venus. Researchers from Harvard University — astronomy professor Avi Loeb and student Amir Siraj — proposed the idea after a group of scientists recently detected signatures of phosphine. Microorganisms can produce […]

Researchers examine how pink sea urchins sharpen their teeth to develop self-sharpening tools
Aside from their fearsome array of spines, sea urchins have another evolutionary edge over other sea creatures: self-sharpening teeth. According to researchers from Northwestern University, the spiny invertebrates, unlike other animals whose teeth are built to resist constant wear and tear, have teeth engineered to chip and weather in such a way that they maintain their sharp […]

Study proposes that the “fight or flight” response is triggered by your bones, NOT adrenaline
In the face of fear and apparent danger, both humans and animals initiate an acute reaction to stress in their bodies. Their breath quickens, their pupils dilate and their hearts begin to pound faster than usual. These programmed changes occur as part of the so-called “fight-or-flight” response. Scientists have long believed that the hormone called adrenaline triggers […]

Biologists identify the protein that makes tendon-muscle connections last a lifetime
The collaboration between muscles and tendons is important for facilitating animal movement. Muscles are contractile tissues whose function is to produce force and motion. What keeps muscles in place and attaches them to the bones is a strong and flexible connective tissue called tendon. Muscles and tendons are connected to each other by attachments, which […]

Scientists study the unique reproductive system of the African pouched rat, a clever animal used to detect land mines and tuberculosis
A species of big rat from Africa possesses an incredibly sensitive nose that can sniff out the presence of deadly tuberculosis and equally dangerous landmines. Researchers recently uncovered more information about the reproductive habits of these useful animals, which can help them breed the notoriously finicky rodents in captivity. The African giant pouched rat (Cricetomys […]

Spider species discovered to use catapult technology to fling sticky webs at prey… previously scientists believed only humans possessed such weapons tech
Scientists at The University of Akron in Ohio have made yet another remarkable discovery about the intricacies of the animal kingdom, which continue to amaze even the brightest minds. Believe it or not, there’s actually a spider out there that’s not only able to spin its web in awe-inspiring wonder, but also pull this web […]

New study shows that wild insects “grow old” – losing some of their physical abilities – before they die
Humans and crickets have at least one trait in common, according to a recently published U.K. study. As they approach the end of their lives, certain physical capabilities start to diminish in a process some may recognize as “aging.” Many wild insects have brief lifespans, especially when compared to humans. Field crickets, for example, only live […]

Study reveals glass knifefish use tiny active sensing motions to keep track of their surroundings
Researchers are finally beginning to understand how the brain of an organism controls its active senses. An experiment with glass knifefish (Eigenmannia virescens) revealed that the tiny active sensing motions performed by the animal are controlled via sensory feedback. The tiny movements increase the accuracy of the data that is being sent to the brain of the fish. These […]

New research finds that the brains of fruit flies work similarly to advanced computer algorithms
Fruit flies and computers apparently follow the same thinking process when it comes to analyzing unknown information. A new study indicated that computer algorithms could take some hints from the way flies identify new smells. A fly can swiftly determine whether or not it has smelled an odor before. Based on the familiarity of the scent, the insect determines […]

Bacteria “gangs” defend their turf by forming “social networks” that release toxins to neutralize enemies, according to new research
Scientists have long known that bacteria can fight other bacteria by producing their own version of antibiotics. The researchers behind a recent study have uncovered another bacterial survival tactic. By generating toxic proteins, certain bacteria become capable of communicating with one another, essentially allowing them to form their own social networks. This remarkable discovery was […]
