- Researchers prove fish-friendly detection method more sensitive than electrofishingon January 21, 2021 at 9:20 pm
Delivering a minor electric shock into a stream to reveal any fish lurking nearby may be the gold standard for detecting fish populations, but it's not much fun for the trout.
- Nature's decline risks our quality of lifeon January 21, 2021 at 9:19 pm
It is no secret that over the last few decades, humans have changed nature at an ever-increasing rate. A growing collection of research covers the many ways this is impacting our quality of life, from air quality to nutrition and income. To better understand how which areas are most at risk, scientists have combed through volumes of literature to present global trends in the relationship between human wellbeing and environmental degradation.
- Scientists make pivotal discovery on mechanism of Epstein-Barr virus latent infectionon January 21, 2021 at 8:13 pm
Researchers at The Wistar Institute have discovered a new enzymatic function of the Epstein-Barr Virus (EBV) protein EBNA1, a critical factor in EBV's ability to transform human cells and cause cancer. Published in Cell, this study provides new indications for inhibiting EBNA1 function, opening up fresh avenues for development of therapies to treat EBV-associated cancers.
- Spitting Cobra venom reveals how evolution often finds the same answer to a common problemon January 21, 2021 at 8:09 pm
A study of spitting cobras reveals how a combination of venom components have evolved to create an instantly painful venom, not once, but on three separate occasions.
- Researchers prove fish-friendly detection method more sensitive than electrofishingon January 21, 2021 at 8:09 pm
Delivering a minor electric shock into a stream to reveal any fish lurking nearby may be the gold standard for detecting fish populations, but it's not much fun for the trout. Scientists have found that sampling stream water for evidence of the presence of various species using environmental DNA, known as eDNA, can be more accurate than electrofishing, without disrupting the fish.
- Snake sex chromosomes say less about sex and more about survivalon January 21, 2021 at 8:09 pm
Sex-specific chromosomes are a dangerous place to be, if you're a gene. Because these chromosomes—Y chromosomes, in humans—do not have a matching chromosome with which to exchange genetic information, they are prone to losing non-essential genes left and right in a process called genetic decay.
- Scientists discover how the potentially oldest coral reefs in the Mediterranean developedon January 21, 2021 at 8:05 pm
A new study from the Institut de Ciències del Mar (ICM-CSIC, Spain) and the National Oceanography Centre brings unprecedented insights into the environmental constraints and climatic events that controlled the formation of these reefs.
- Novel effector biology research provides insights into devastating citrus greening diseaseon January 21, 2021 at 8:04 pm
Citrus greening disease, also known as Huanglongbing (HLB), is devastating to the citrus industry, causing unprecedented amounts of damage worldwide. There is no known cure. Since the disease's introduction to the United States in the early 2000s, research efforts have increased exponentially. However, there is still a lack of information about the molecular mechanism behind the disease.
- How cells 'eat' their own fluid componentson January 21, 2021 at 8:01 pm
Autophagy is a fundamental cellular process by which cells capture and degrade their own dysfunctional or superfluous components for degradation and recycling. Recent research has revealed that phase separated droplets have a range of important functions in cells. An international collaboration between German, Norwegian, and Japanese researchers has unraveled the mechanisms underpinning both how these droplets are captured through autophagy, as well as how droplets can serve as a platform from which structures facilitating cytosolic autophagy arise.

A study of spitting cobras, published in Science reveals how a combination of venom components have evolved to create an instantly painful venom, not once, but on three separate occasions.
- Invasive tawny crazy ants have an intense craving for calcium – with implications for their spread in the USon January 21, 2021 at 6:20 pm
In a recent study, my colleagues and I discovered micronutrients in the ground can control populations of invasive crazy ants (Nylanderia fulva).
- See how they run: 'Exercise protein' doubles running capacity, restores function and extends healthy lifespans in older miceon January 21, 2021 at 6:19 pm
A new study shows that humans express a powerful hormone during exercise and that treating mice with the hormone improves physical performance, capacity and fitness. Researchers say the findings present new possibilities for addressing age-related physical decline.
- This Great Lakes fish may have evolved to see like its ocean ancestors didon January 21, 2021 at 6:19 pm
In the dark waters of Lake Superior, a fish species adapted to regain a genetic trait that may have helped its ancient ancestors see in the ocean, a study finds. 'Evolution is often thought of as a one-way process, at least over deep time, but in this example, over 175 million years, we have this reversal back to a much earlier ancestral state,' one of the researchers says.
- Message in a bottle: Info-rich bubbles respond to antibioticson January 21, 2021 at 6:18 pm
Researchers describe the effects of antibiotics on membrane vesicles, demonstrating that such drugs actively modify the properties of vesicle transport. Under the influence of antibiotics, MVs were produced and released by bacteria in greater abundance and traveled faster and further from their origin. The work sheds new light on these important information-carrying entities, implicated in many cellular communication processes, including antibiotic resistance.
- Estrogen receptors in mom's placenta critical during viral infectionon January 21, 2021 at 6:17 pm
A team of researchers has found a mechanism that protects a fetus from harm when the mother's innate immune system responds to a viral infection. Inflammation that would harm the fetus is dampened by a cell-surface estrogen receptor called GPER1 that is especially abundant in the placenta and fetal tissues.
- Climate-related species extinction possibly mitigated by newly discovered effecton January 21, 2021 at 6:08 pm
Changes in climate that occur over short periods of time influence biodiversity. For a realistic assessment of these effects, it is necessary to also consider previous temperature trends going far back into Earth's history.
- As oceans warm, large fish struggleon January 21, 2021 at 6:01 pm
Warming ocean waters could reduce the ability of fish, especially large ones, to extract the oxygen they need from their environment. Animals require oxygen to generate energy for movement, growth and reproduction. In a recent paper in the Proceedings of the National Academy of Science, an international team of researchers from McGill, Montana and Radboud universities describe their newly developed model to determine how water temperature, oxygen availability, body size and activity affect metabolic demand for oxygen in fish.
- Seeds transfer their microbes to the next generationon January 21, 2021 at 5:47 pm
Scientists have been pondering if the microbiome of plants is due to nature or nurture. Research at Stockholm University, published in Environmental Microbiology, showed that oak acorns contain a large diversity of microbes, and that oak seedlings inherit their microbiome from these acorns.
- Pioneering new technique could revolutionise super-resolution imaging systemson January 21, 2021 at 5:46 pm
Scientists have developed a pioneering new technique that could revolutionize the accuracy, precision and clarity of super-resolution imaging systems.
- Message in a bottle: Info-rich bubbles respond to antibioticson January 21, 2021 at 5:34 pm
Once regarded as merely cast-off waste products of cellular life, bacterial membrane vesicles (MVs) have since become an exciting new avenue of research, due to the wealth of biological information they carry to other bacteria as well as other cell types.
