Despite significant advances in medicine, cancer remains the second leading cause of death worldwide (WHO, 2018). One of the main approaches to the destruction of cancer cells, along with cancer immunotherapy, is to initiate cell death through chemo- and radiotherapy. In their article in Nature Reviews Cancer, several researchers have proposed a new look at the role of ferroptosis (a type of cell death) in the development of cancer.

Danger avoidance can be genetically encoded for four generations, biologists say

Princeton University researchers have discovered that learned behaviors can be inherited for multiple generations in C. elegans, transmitted from parent to progeny via eggs and sperm cells. The paper detailing this finding, by Rebecca Moore, Rachel Kaletsky and Coleen Murphy, appears in the June 13 issue of the journal Cell.

How old are your organs? To scientists' surprise, organs are a mix of young and old cells

Scientists once thought that neurons, or possibly heart cells, were the oldest cells in the body. Now, Salk Institute researchers have discovered that the mouse brain, liver and pancreas contain populations of cells and proteins with extremely long lifespans—some as old as neurons. The findings, demonstrating "age mosaicism," were published in Cell Metabolism on June 6, 2019. The team's methods could be applied to nearly any tissue in the body to provide valuable information about lifelong function of non-dividing cells and how cells lose control over the quality and integrity of proteins and important cell structures during aging.

New research shakes up the sloth family tree

New studies by two research teams published today in the journals Nature Ecology and Evolution and Current Biology challenge decades of accepted scientific opinion concerning the evolutionary relationships of tree sloths and their extinct kin. The research teams used different molecular tools—the protein collagen in one case and the mitochondrial genome in the other—but they reached nearly the same results. The concurrent findings are significant because they provide molecular evidence that appears to overturn a longstanding consensus, based on the study of anatomical features, regarding how the major groups of sloths are related to one another.

Two new species of 'tweezer-beaked hopping rats' discovered in Philippines

Just about everybody loves peanut butter. We put it on sandwiches and in candy, we use it to trick our dogs into taking their heartworm pills, and, when we have to, we bait mouse traps with it. But, as scientists learned when trapping rodents in the mountains of the Philippines, peanut butter isn't for everyone. A highly distinctive (weird-looking) group of rodents sometimes called "tweezer-beaked hopping rats" don't care for peanut butter, but love earthworms. Armed with this knowledge (and worms), the scientists discovered two new species of the tweezer-beaked hopping rats. The discovery was announced in the Journal of Mammalogy.

Dynamics of key viral attack strategy visible for first time

Many infectious viruses, from HIV to West Nile, rely on a fundamental biological process called frameshifting to maximize their attack. Long identified as a key mechanism that viruses use to proliferate inside their hosts, the real-time dynamics of frameshifting had never been directly observed, until now.

Freshwater stingray venom varies according to sex and age

There is no antidote or specific treatment for freshwater stingray venom, although accidents involving these animals are frequent on rivers in the Amazon and other regions.

Is sex primarily a strategy against transmissible cancer?

One of the greatest enigmas of evolutionary biology is that while sex is the dominant mode of reproduction among multicellular organisms, asexual reproduction appears much more efficient and less costly. However, in a study publishing on June 6 in the open-access journal PLOS Biology, researchers suggest that sexual reproduction is favored by selection because, unlike asexual reproduction, it not only provides important evolutionary advantages in constantly changing environments, but also prevents the invasion of transmissible cancer, or "cheater" cells.

Social interactions impact climate change predictions, study reveals

Something as simple as chatting with your neighbours about their new energy-efficient home renovations can affect wider climate change predictions, a new University of Guelph study reveals.

Dogs mirror owner's stress

The levels of stress in dogs correlate with the stress of their owners, according to a new study from Linköping University, Sweden. The scientists believe that dogs mirror their owner's stress level, rather than vice versa. The study has been published in the scientific journal Scientific Reports.

Unusual Japanese plant inspires recalculation of equation used to model leaf arrangement patterns

Leaves are enjoyed for their shade, autumn colors, or taste, and the arrangement of leaves on a plant is a practical way to identify a species. However, the details of how plants control their leaf arrangement have remained a persistent mystery in botany. A Japanese plant species with a peculiar leaf pattern recently revealed unexpected insight into how almost all plants control their leaf arrangement.

Student gives possible explanation for female mating preferences that decrease male survival chances

Pavitra Muralidhar, a Ph.D. student in the Department of Organismic and Evolutionary Biology at Harvard University, has developed a theory to explain why females of some species are more attracted to some males who have a lesser chance of survival. In her paper published in the journal Nature, she outlines her theory of selfish sex chromosomes and how it might work in nature. Mark Kirkpatrick, with the University of Texas has published a News and Views piece in the same journal issue, outlining the work done by Muralidhar.

Sediment from fishing choking out sea sponges, study shows

Sediment stirred up from fishing activity has a detrimental effect on reef-building sea sponges in northern British Columbia, according to a new study by University of Alberta biologists.

What organizes the genome in the nucleus?

Spatial separation of active from inactive fractions of the genome in the cell nucleus is crucial for gene expression control. A new study uncovers leading mechanisms of such separation and turns our picture of the nucleus upside down.

How flow shapes bacterial biofilms

EPFL biophysicists have taken a systematic look into how bacterial biofilms are affected by fluid flow. The findings can give us clues about the physical rules guiding biofilm architecture, but also about the social dynamics that shape evolution.

Translation of genes more complex than expected

Researchers from Marvin Tanenbaum's group at the Hubrecht Institute have shown that translation of the genetic information stored in our DNA is much more complex than previously thought. This discovery was made by developing a type of advanced microscopy that directly visualizes the translation of the genetic code in a living cell. Their study is published in the scientific journal Cell on June 6th.

Just a phage? How bacteria's predators can shape the gut microbiome

The gut microbiome is a complex, interconnected ecosystem of species. And, like any ecosystem, some organisms are predators and some are prey. A new study led by investigators at Brigham and Women's Hospital and the Wyss Institute investigates the impact of bacteriophage, viruses that infect and kill bacteria. They find that phage can have a profound impact on the dynamics of the gut microbiome, not only affecting certain species directly but also having a cascading effect on others. Phage may also be impacting their human host by modulating metabolites, including chemical substances found in the brain. The team, which includes first author Bryan Hsu, Ph.D., and co-corresponding senior author Pamela Silver, Ph.D., at the Wyss Institute, and Lynn Bry, MD, Ph.D., at the Brigham and director of the Massachusetts Host-Microbiome Center, has published its results in Cell Host & Microbe.

The deep learning dive: how cells regulate division

Combining tissue imaging and artificial intelligence, Hollings Cancer Center researchers at the Medical University of South Carolina probed deeper into how cell division cycles are regulated, in this study released online in the May 2019 issue of Cell Reports.

Scientist looks to resurrect Hong Kong's 'Pearl of the Orient' past

On a raft floating off Hong Kong's rural eastern coastline former investment banker turned scientist Yan Wa-tat patiently scrapes barnacles off some 2,000 oysters—a tiresome but crucial part of his mission to bring back pearl farming.

Scientists unlock genetic mystery: Why corals reject life-saving algae

Algae can help corals adapt to warming seas but scientists have discovered they have relationship issues. It's complicated.

Many plant species at risk of extinction—and we're blind to danger this poses to life on Earth

Up to 1 million species may go extinct due to human activity according to a recent report, some within decades. We all know the mammals in trouble—polar bears, giant pandas and snow leopards—but how many of us could name an endangered plant? A 2019 report assessed 28,000 plant species and concluded that about half of them were threatened with extinction.

How we're helping the western ground parrot survive climate change

When a threatened species is found only in one small area, conservationists often move some individuals to another suitable habitat. This practice, called "translocation," makes the whole species less vulnerable to threats.

Why humans (or something very similar) may have been destined to walk the Earth

What would happen if the hands of time were turned back to an arbitrary point in our evolutionary history and we restarted the clock? American paleontologist Stephen Jay Gould proposed this famous thought experiment in the late 1980s—and it's one that still grips the imagination of evolutionary biologists today.

A bean for all seasons?

Biology professor and researcher Christopher Cullis said he pondered two big questions when he first caught sight of the wild marama bean plant, its definitive patches of green leaves standing out in contrast from among an otherwise parched and brown Namibian landscape.

Talking to each other—how forest conservation can succeed

Forest conservation can be a source of tension between competing priorities and interests from forestry, science, administration and nature conservation organisations. The different stakeholders can create the public impression of disagreement with regard to the objectives and measures in forest conservation. Scientists from the University of Göttingen, the HAWK University of Applied Sciences and Arts Hildesheim/Holzminden/Göttingen and the Northwest German Forest Research Institute have developed a framework of conservation objectives whereby targets for nature conservation can be compared and analysed. The study was published in Nature Conservation.

Northeastern deer more susceptible to wasting disease than those to the west

Some deer are more susceptible to chronic wasting disease that is spreading through herds of white-tailed deer across much of the United States, according to Penn State researchers, who have identified a panel of genetic markers that reliably predict which animals are most vulnerable to the contagious neurological disorder.

What's fair game on the high seas?

Sustainability-driven new research could one day help tuna fisheries cast their nets more selectively, mitigating unintentional "bycatch" of undersized fish and off-limits species.

New model predicts impact of invasive lionfish predators on coral reefs

A new model is providing insight into the impact of invasive lionfish on coral reefs in the Atlantic Ocean and Caribbean Sea. The venomous predatory fish has invaded more than 7.3 million square kilometres in the Atlantic and Caribbean, wreaking havoc among native fish populations.

Days are numbered for Norway's fur farms

Baby minks, their skin still smooth and furless, snuggle up against one another under a pile of hay, letting out the occasional squeal: this sight will soon be a thing of the past at Norway's fur farms.

Court fight could affect future of bison in Montana

The Democratic governor of Montana who is running for president and the Republican secretary of state who wants his job were locked in a constitutional dispute over a uniquely Western issue that lies at the intersection of politics, wildlife, agriculture and property rights.

Emerging frontiers in phenological research

As climate change looms, we urgently need to understand how ecosystems will respond. Plant phenology, or the timing of developmental events like flowering, offers a powerful lens to make sense of the changes we are likely to see. Phenology is both driven by climate and deeply impacts ecosystem functioning. The timing of trees leafing out, blooming, and fruiting are key events in ecosystems, and even small perturbations in this timing can have drastic, cascading effects across an ecosystem. A recent special issue of Applications in Plant Sciences titled "Emerging Frontiers in Phenological Research" presents several studies on the forefront of phenological research.

'Fishing a line' coupled with clockwork for daily rhythm

Organisms on this planet, including human beings, exhibit a biological rhythm that repeats about every 24 hours to adapt to the daily environmental alteration caused by the rotation of the earth. This circadian rhythm is regulated by a set of biomolecules working as a biological clock. In cyanobacteria (or blue-green algae), the circadian rhythm is controlled by the assembly and disassembly of three clock proteins, namely, KaiA, KaiB, and KaiC. KaiC forms a hexameric-ring structure and plays a central role in the clock oscillator, which works by consuming ATP, the energy currency molecule of the cell. However, it remains unknown how the clock proteins work autonomously for generating the circadian oscillation.
