How a single nerve cell can multiply

Neurons are constantly performing complex calculations to process sensory information and infer the state of the environment. For example, to localize a sound or to recognize the direction of visual motion, individual neurons are thought to multiply two signals.

Researchers have now discovered in fruit flies the biophysical basis that enables a specific type of neuron to multiply two incoming signals. This provides fundamental insights into the algebra of neurons -- the computations that may underlie countless processes in the brain.

Genome of Steller’s sea cow decoded

During the Ice Age, giant mammals such as mammoths, sabre-toothed cats and woolly rhinoceroses once roamed Northern Europe and America. The cold oceans of the northern hemisphere were also home to giants like Steller's sea cow, which grew up to eight meters long and weighed up to ten tons, and has been extinct for around 250 years. Now an international research team has succeeded in deciphering the genome of this ice-age species from fossil bones. They also found an answer to the question of what the genome of this extinct species of sea cow reveals about present-day skin diseases.

Important step towards fasting-based therapies

Voluntary fasting, for example interval fasting, is beneficial to health for many people, depending on their individual condition. For example, controlled periods of starvation can prevent and improve diseases such as diabetes and obesity. Researchers have now found that the immune system plays an important role in ensuring the positive effects of fasting on our bodies. The new findings will help develop more effective therapies based on fasting.

A new multipurpose on-off switch for inhibiting bacterial growth

Researchers have discovered an antitoxin mechanism that seems to be able to neutralize hundreds of different toxins and may protect bacteria against virus attacks. The mechanism has been named Panacea, after the Greek goddess of medicine whose name has become synonymous with universal cure. The understanding of bacterial toxin and antitoxin mechanisms will be crucial for the future success of so-called phage therapy for the treatment of antibiotic resistance infections, the researchers say.

Unique seagrass nursery aims to help Florida's starving manatees

More than 1,000 manatees died in 2021, due mostly to starvation. They consume about 100 pounds of seagrass a day, and this staple food is now scarce in Florida's Indian River Lagoon (IRL). A new study shows that about 7,400 acres of seagrasses were lost in the IRL between 1943 and 1994. Between 2011 and 2019, about 58 percent of seagrasses were lost. To help with recovery efforts, researchers are experimenting with growing seagrass in large tanks and then transplanting it into the IRL to try to restore some of the lost seagrass beds.

A new study demonstrates the ability of the mutant Kras oncogene to use genetic reprogramming to make cells more stem-like and plastic; it resolves the long-standing debate over why Kras is so special in tumor formation. They were also able to identify an effector complex that can be targeted for therapeutic treatment against mutant Kras.

Underwater 'breathing' plants could be key to stress-resistant crops

Wetland plants have a high tolerance against flooding due to the formation of 'lysigenous aerenchyma,' air channels that help transfer gases to the submerged roots. These channels also help the plant withstand drought and nutrient deficiency. Now, scientists investigate the underlying mechanism of aerenchyma formation to understand the phenomenon better, opening doors to the development of crops that are resilient against extreme weather changes.

Preventing pandemics costs far less than controlling them

An analysis by epidemiologists, economists, ecologists and biologists at 21 institutions finds we could reduce the risks of future pandemics by investing as little as 1/20th of the losses incurred so far from COVID into conservation measures designed to stem the spread of zoonotic viruses from wildlife to humans in the first place. This includes funding programs to train more veterinarians, create a global database of virus genomics, and end tropical deforestation and wildlife trafficking.

Exploring the strategies of categorization

Our mental ability to divide the complex world into categories makes our daily life much easier. But how do we categorize? What kind of stimulus properties do we assess? Researchers have come a step closer to answering these questions with the help of pigeons. They discovered that birds use different strategies to successfully learn categories. To gather data, the researchers used a novel research method. To this end, they combined so-called virtual phylogenesis, in which artificial stimuli are generated by computers, with a machine learning approach, namely an automated evaluation of the birds' pecking behavior.

Different autism risk genes, same effects on brain development

Researchers have found that three different autism risk genes actually affect similar aspects of neuron development and the same neuron types, although each gene acted through unique molecular mechanisms. Additionally, a person's specific genomic background fine-tuned the genes' effects. The study was conducted using miniature 3D models, or 'organoids,' of the human cerebral cortex, the part of the brain responsible for cognition, perception, and language. The results advance our understanding of autism spectrum disorder and are a first step toward finding treatments for the condition.

Scientists uncover 'missing' plastics deep in the ocean

A new study unveils the prevalence of plastics in the entire water column of an offshore plastic accumulation zone in the southern Atlantic Ocean and implicates the ocean interior as a crucial pool of 'missing' plastics. Results show that small microplastics are critical, underexplored and integral to the oceanic plastic inventory. In addition, findings show that weak ocean current systems contribute to the formation of small microplastics hotspots at depth, suggesting a higher encounter rate for subsurface particle feeders like zooplankton.
