These Small, Stealthy Bats Use High-Frequency Vocalizations to Keep Their Chatter Out of the Range of Predators and Prey
New research shows that proboscis bats communicate with each other and echolocate at higher frequencies than scientists expected. This could help the animals sneak up to their targets and evade creatures that want to eat them The tiny proboscis bat sits outside on tree trunks during the day and eats insects like moths and mosquitoes, keeping the bug population in check.
Weill Cornell awarded $17.4M grant to develop shorter TB treatment regimen
Researchers at Weill Cornell Medicine have received a $17.4 million, five-year grant from the National Institute of Allergy and Infectious Diseases to discover new approaches to shorten tuberculosis (TB) treatment, potentially making it easier for patients to complete therapy. The researchers aim to shift TB drug development toward creating new drugs from the start to work in the combinations needed to cure TB.
Ants Can Get Distracted by Cookies, Chips and Other Junk Food. Here’s Why That Could Be a Problem for the Environment
The insects enjoy snack crumbs, but new research shows that this unnatural food source can divert them from one of their most significant roles: dispersing plant seeds Summer is a time for picnics and barbecues, but a few uninvited guests occasionally crash the party. These guests—ants—have developed a taste for the same processed foods that humans enjoy.
Targeting inflammation may help overcome drug resistance in colon cancer
Chemotherapy drugs that target a common mutation in colorectal cancer rapidly lose efficacy in patients, leading to relapse. According to a new preclinical study from Weill Cornell Medicine investigators, colorectal tumors often find multiple ways to survive treatment, including additional genetic mutations and activation of cellular pathways typically associated with inflammation and regeneration.
When Vampire Bats Become Close Friends, They Start ‘Talking’ Like Each Other
New research shows that just like humans, vampire bats with deep social relationships use similar sounds as one another to communicate Sometimes when people hang around one another long enough, they begin using the same slang, vocal inflections and pitch. Humans can pick up and mimic the sounds and words of the people around them, especially those with whom they have close personal relationships. But humans don’t have a unique claimon this kind of behavior, which is called vocal convergence.
See Ten Gorgeous Photographs of Lions and Discover What Makes the Majestic Felines Special
A new book of essays and images reveals the history of the big cats and how they’ve become a vulnerable species today, and uncovers little-known facts about them Long considered symbols of royalty and strength, lions have fascinated humans for centuries. Although we are their biggest admirers, we are also one of their , poaching them for their skins, encroaching on their territories, killing them to protect livestock and hunting them as trophies.
How One Chihuahua Proved to Be a Link to the Ancient Dogs That Moved to Latin America With the Spread of Agriculture
New research shows that ancient dogs did not join Indigenous people in Central and South America until farming became popular—especially of maize The tiny, feisty Chihuahua is a relic of sorts. As European settlers arrived in the Americas 500 years ago, their dogs quickly replaced native canines, obliterating detectable genetic traces of them—except in a few distinct breeds such as the Chihuahua.
Living lenses? Glass-coated microbes might take better photos
bacteria: (adj: bacterial) Single-celled organisms. These dwell nearly everywhere on Earth, from the bottom of the sea to inside other living organisms (such as plants and animals). Bacteria are one of the three domains of life on Earth. biologist: A scientist involved in the study of living things. cell: (in biology) The smallest structural and functional unit of an organism. Typically too small to see with the unaided eye, it consists of a watery fluid surrounded by a membrane or wall.
Mosquitoes taste you before they decide to bite
amino acids: Simple molecules that occur naturally in plant and animal tissues and that are the basic building blocks of proteins. behavior: The way something, often a person or other organism, acts towards others, or conducts itself. biologist: A scientist involved in the study of living things. cell: (in biology) The smallest structural and functional unit of an organism. Typically too small to see with the unaided eye, it consists of a watery fluid surrounded by a membrane or wall.
Immune complex removes receptors from stem cells to protect against cancer, preclinical study finds
A group of immune proteins called the inflammasome can help prevent blood stem cells from becoming malignant by removing certain receptors from their surfaces and blocking cancer gene activity, according to a preclinical study by Weill Cornell Medicine investigators. The study, published in Nature Immunology, may lead to therapies that target the earliest stages of cancer.
These Fish Transformed Their Dorsal Fins Into Taste Buds
When ichthyologist Paulo Presti, a graduate student at the University of São Paulo in Brazil, found a jar containing a preserved Remo flounder inside, he was stumped. “When I turned the jar to look at the specimen, I saw a strange little thing on its head on its blind side,” he says.
Many flowers and ferns lure in ants as bodyguards
Earth’s Cretaceous Period is well-known for its huge, lumbering dinosaurs. But many smaller organisms were shaping the landscape at the same time. And the results of these battles can still be seen in today’s woods and gardens. This period is when the first flowering plants appeared. Some insects developed a taste for those and other plants. In time, some plants found a way to fight back — indirectly. They recruited ants to fend off savaging beetles, flies and caterpillars.
‘Fearsome’ Saber-Toothed Cats Needed Their Baby Teeth and Mommies, Too
With long, thin blades protruding from their mouths, saber-toothed cats roamed the Earth during the last ice age, alongside woolly mammoths, giant ground sloths and mastodons. They lived from the Eocene to Pleistocene epochs, which spanned over 50 million to about 11,700 years ago. Not all saber-toothed creatures were felids, or “true cats,” which are the animals we consider to be “cats” today, such as lions, tigers and housecats.

Starchy Bioplastic Could Make Soggy Paper Straws a Thing of the Past
In the fight against pollution, several regions in the U.S. have banned the use of plastic straws. Alternative materials exist, but most options are either too expensive to scale up, go limp in drinks or taste bad. But now, a team reporting in ACS Omega has developed a new type of bioplastic film from all-natural, degradable materials that can be rolled into a straw that doesn’t get soggy and is stronger than plastic.

Weaponizing Oxygen to Kill Infections and Disease
The life-threatening bacteria called MRSA (methicillin-resistant Staphylococcus aureus) can cripple a hospital since it spreads quickly and is resistant to treatment. But scientists report that they are now making advances in a new technique that avoids antibiotics. Instead, they are using light to activate oxygen, which then wipes out antibiotic-resistant bacteria. The method also could be used to treat other microbial infections, and possibly even cancer.
Elephant and Cow Manure for Making Paper Sustainably
It’s likely not the first thing you think of when you see elephant dung, but this material turns out to be an excellent source of cellulose for paper manufacturing in countries where trees are scarce, scientists report. In regions with plenty of farm animals such as cows, upcycling manure into paper products could be a cheap and environmentally sound method to get rid of this pervasive agricultural waste.
Explaining the #Bingate Controversy to America
I know this series aired more than four years ago, and this article is about to be four years old, so I admit it seems a bit nuts to be commenting on it now (although in my defense, I only recently saw it). I don't understand this need to whitewash the events. Diana didn't "accidentally" leave Iain's ice cream out of the freezer. She intended to take it out to make room for her own, and she did.
Microalgae’s impact on human and animal nutrition, April 2024
Programming plants Computers have revolutionized how people do business, interact with friends, and find information. With the right inputs, computers churn out loads of information or, with artificial intelligence, they can create brand-new stories, poems, or images. The possibilities seem endless.
Begin at the end when isolating plant proteins
From body builders to vegans to those just wanting to lose a little weight, it seems that everyone is trying to get more protein in their diets. In specialty nutrition stores and the health food aisle of the grocery store, protein-packed products dominate. High-protein bars and shakes are popular, as is pure protein powder. But whereas animal meat is naturally high in protein, plants also contain a high percentage of oils, fats, carbohydrates, and fiber.
