White-nose syndrome in little brown bats: how to protect them
In a recent study, scientists discovered that white-nose syndrome (WNS)-affected little brown bats significantly boosted their foraging activities at artificial insect buffets. Bats will be able to boost their fat reserves before and during hibernation thanks to the bug buffets, which are situated close to hibernation areas. They should be able to survive the illness as a result. For bats with WNS, … Continue reading White-nose syndrome in little brown bats: how to protect them

A range-shifting damselfly species is now cohabitating alongside its UK relative
New research demonstrates that an introduced European species of damselfly offers only a little threat to native British damselflies and dragonflies. The little red-eyed damselfly has expanded its range northward from the Mediterranean as temperatures rise. In 1999, it was first seen in the UK, and since then it has spread throughout the country. The new research examined data from the British … Continue reading A range-shifting damselfly species is now cohabitating alongside its UK relative

Scientists have found out how electrochemical energy in bacteria makes them resistant to antibiotics
The threat posed by antibiotic-resistant microorganisms to world health is growing. Each year, millions of people die as a result of bacterial infections that acquire genetic resistance to antibiotics. However, one of the many ways that bacteria might resist antibiotics is through genetic resistance. Texas A&M University researchers are looking at how bacteria might become resistant to drugs without gaining new genes … Continue reading Scientists have found out how electrochemical energy in bacteria makes them resistant to antibiotics

Fever following cancer treatment may be facilitated by mucus-eating gut bacteria
Neutropenia is the depletion of neutrophils, a type of white blood cell, which is a typical side effect of cytotoxic cancer treatments like chemotherapy and radiation. Patients with severe neutropenia often experience fever. The mucus-degrading commensal bacterium Akkermansia muciniphila was identified as the possible causative agent of this fever, according to research published on November 16 in Science Translational Medicine.

After a century of misidentification, a species of giant tortoise has been uncovered
Several species of the gigantic reptiles originally roamed alongside their much smaller counterparts in the southwestern region of Madagascar, which was a hotspot for tortoises. Now, researchers may complete that picture with a new species. Astrochelys rogerbouri, which the scientists estimated to have had a carapace of around 50 centimeters long, would have been one of the island’s giant tortoises. Despite the … Continue reading After a century of misidentification, a species of giant tortoise has been uncovered

Leaf-clipping and other leaf-modifying actions among East African chimpanzees as a form of gestural dialects
University of St. Andrews researchers have discovered that chimpanzees in two nearby groups in Uganda’s Budongo Forest utilize leaf motions in several languages to communicate with one another. A community of chimpanzees will employ their own preferred way of leaf-modifying motion, and nearby groups can use different ones, resulting in each group having its own gestural language, according to research published on Jan. 5 … Continue reading Leaf-clipping and other leaf-modifying actions among East African chimpanzees as a form of gestural dialects

Researchers have developed a blood test that may identify the ‘toxic’ protein years before Alzheimer’s symptoms appear
Most people diagnosed with Alzheimer’s today have already shown typical symptoms including memory loss. Once symptoms have progressed so far, the best treatment choices do nothing more than slow the disease’s progression. However, studies have revealed that the seeds of Alzheimer’s are planted years, if not decades, before the onset of any cognitive deficits that would allow for a diagnosis. Amyloid beta … Continue reading Researchers have developed a blood test that may identify the ‘toxic’ protein years before Alzheimer’s symptoms appear

The ability of elephants to remain in their seasonal habitat despite environmental change
Dr. Rhea Burton-Roberts, a biologist and lecturer at Bangor University, found that elephants had extremely stable seasonal migratory patterns over years. In Kruger National Park, Rhea found that elephant family groups prefer to stay in regions that they know well, but a scarcity of food during very dry seasons might lead them to move their foraging to less known habitats. Her research was … Continue reading The ability of elephants to remain in their seasonal habitat despite environmental change

The transformation of a tentacle into a foot
Differentiated cells are the building blocks of all multicellular organisms, including humans, animals, and plants. Thus, the cells that make up the skin are not the same as the cells that line the digestive tract, nor do they serve the same purpose. However, how these cells are able to maintain their unique characteristics remains uncertain. One of the important regulators, the transcription factor … Continue reading The transformation of a tentacle into a foot

The process by which humans began to lose their body hair
Humans don’t have it, but other mammals like orangutans, mice, and horses do. For a long time, it has been mysterious to scientists why humans have such a small amount of body hair compared to other mammals. However, the story of how humans and other mammals lost their locks is just beginning to be revealed thanks to a groundbreaking analysis of genetic … Continue reading The process by which humans began to lose their body hair

As a result of coral bleaching, reef fish needs to relearn the rules of interaction
New research shows that mass coral bleaching events are making it tougher for some reef fish species to distinguish between rivals. After widespread loss of coral due to bleaching, scientists studying reefs in five parts of the Indo-Pacific discovered that butterflyfish individuals’ capacity to detect competing species and respond appropriately was compromised. As a result of this change, the butterflyfishes are less likely to … Continue reading As a result of coral bleaching, reef fish needs to relearn the rules of interaction

What is decompression sickness?
When the internal pressure of the body drops too low, a condition known as decompression sickness (DCS) can set in. DCS occurs when gases that were previously dissolved in the blood or other body tissues become undissolved. Divers who come up to the surface of the water too quickly are susceptible to this illness, as are pilots flying at high altitudes in … Continue reading What is decompression sickness?
