Mammals Can Breathe Through Their Intestines
fahrbot-bot shares a report from Gizmodo: When pressed for oxygen, some fish and sea cucumbers will use their lower intestines to get a little extra out of their environment. Now, a team of Japanese researchers say that mammals are also capable of re.....»»
These 3D-printed pipes inspired by shark intestines outperform Tesla valves
Prototypes control fluid flow in a preferred direction with no need for moving parts. Enlarge / Shark intestines are naturally occurring Tesla valves; scientists have figured out how to mimic their unique structure. (credit: Sara.....»»
Naked mole-rat found to have lost infection-resistant proteins
Scientists have found that the naked mole-rat—an underground rodent that lives up to 40 years—has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious.....»»
Ancient DNA helps uncover the Iberian lynx"s potential secret weapon against extinction
Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a "genetic database" to fall back on to ad.....»»
Scientists in South Africa say they have identified the first known outbreak of rabies in seals
Scientists in South Africa say they have identified an outbreak of rabies in seals that is believed to be the first time the virus has spread in sea mammals......»»
"Scuba-diving" lizards use bubble to breathe underwater and avoid predators
Presenting the world's smallest (and scrappiest) scuba diver: A species of semi-aquatic lizard produces a special bubble over its nostrils to breathe underwater and avoid predators, according to new research from Binghamton University, State Universi.....»»
Environment takes center stage as global summits loom
Global warming. Disappearing plant and animal species. Fertile land turning to desert. Plastic in the oceans, on land, and the air we breathe......»»
Backside breathing and pigeon bombers studies win Ig Nobel prizes
Mammals that can breathe through their backsides, homing pigeons that can guide missiles and sober worms that outpace drunk ones: these are some of the strange scientific discoveries that won this year's Ig Nobels, the quirky alternative to the Nobel.....»»
Another rare Javan rhino calf spotted at Indonesia park
A new Javan rhino calf has been spotted in an Indonesian national park, the facility's head said Friday, further boosting hopes for one of the world's most endangered mammals after two other sightings this year......»»
Scientists discover crude oil decimates sea otter buoyancy
Sea otters are famed for their luscious pelts, but the fur almost led to their extinction. By 1938, only a tiny population of ~50 remained clinging to the central California coast. Since then, the mammals have battled back. However, the charismatic c.....»»
Spiny mice point the way to new path in social neuroscience
Scientists have zeroed in on brain circuitry powering the desire of spiny mice to live in large groups, opening the door to a new model for the study of complex social behaviors in mammals......»»
Taiwan volunteers fight rise in whale and dolphin strandings
Taiwanese volunteers gathered around a large inflatable whale as they learned how to help beached sea mammals—an increasingly common sight across the island......»»
How fruit flies use internal representations of head direction to support goal-directed navigation
Animal behavior is known to rely on transforming sensory information into motor commands, often influenced by an animal's internal needs. While in mammals and other large animals this process is supported by complex brain processes, simpler versions.....»»
Rare whale species observed during recent Antarctic expedition
Research by Wageningen Marine Research and partners on the relationship between sea ice and the Southern Ocean food web investigates various components of that food web, including the so-called "top predators," or seabirds and marine mammals. To map.....»»
What the unique shape of the human heart tells us about our evolution
Mammals, from the mighty blue whale to the tiny shrew, inhabit nearly every corner of our planet. Their remarkable adaptability to different environments has long fascinated scientists, with each species developing unique traits to survive and thrive.....»»
Brazilians "struggling to breathe" as Amazon burns
Residents of Porto Velho in the Brazilian Amazon have barely seen sunlight in days as a thick cloud of smoke from forest fires envelops their city......»»
Some solitary mammals have surprisingly social lives: What one researcher has learned from a tiny south African rodent
We probably all know someone who lives a solitary life. But not everyone realizes that there are solitary individuals in the animal kingdom, too. Examples of solitary species are some shrews, and large predators, such as black bears (Ursus americanus.....»»
Using dental growth rings scientists reveal differences in growth patterns between ancient and modern mammals
A study published in Science Advances reveals how early mammals grew and developed during their pivotal Jurassic radiation. Using a technique called synchrotron X-ray tomography to image growth rings in fossilized tooth roots, the researchers were ab.....»»
Plants offer fruit to insects to disperse dust-like seeds, botanist discovers
Fruit exist to invite animals to disperse the swallowed seeds. A Kobe University research team found that plants targeting insects rather than birds or mammals for this service are more common than previously thought. These plants produce dust-like s.....»»
"Baby talk:" Decoding how children"s vocal and cognitive cues sway adults
Compared to other mammals, human children are dependent on their caregivers for a remarkably long time. Throughout the ages, they have developed "psychological tactics" to endear themselves to adults and thus enhance their chances of survival. This p.....»»
Timber plantations near urbanized areas support the movement of small and medium-sized terrestrial mammals
In the fight to mitigate climate change and deforestation in the tropics, timber plantations have emerged as a promising strategy for reforesting degraded land and connecting patches of natural forest. Often, these are species with commercial value f.....»»
