Study unlocks clues in mystery of naked mole-rats' exceptional fertility

Introduction For many species, aging often comes with a decrease in fertility. Humans and other mammals, for instance, become less fertile with age. However, an incredible exception to this rule can be found in the mysterious, subterranean wonders of the animal kingdom – the naked mole-rats. Little is known about these fascinating creatures, but one thing is certain: their remarkable lifespan comes with eternal fertility. Now, a new study published in Nature Communications explains the secrets behind their indefinite fertility, with exciting potential implications for humans. What are Naked Mole-Rats? Naked mole-rats (Heterocephalus glaber) are small, almost hairless rodents native to eastern Africa. These extraordinary creatures live longer than any other rodent species, with lifespans of up to 40 years. Remarkably, they also remain fertile throughout their whole lifespan. Though they look like something out of a science fiction movie – with their bulbous eyes and wrinkly skin – naked mole-rats are some of the most fascinating creatures on the planet. They live in vast, underground tunnel systems and are the only known eusocial mammal, meaning their social structure resembles that of social insects like bees and ants. Unique Reproductive Biology Until recently, scientists were at a loss to explain the naked mole-rats' indefinite fertility. But a new study from the University of Rochester reveals a unique mechanism behind their longevity and reproductive success. The researchers identified a key factor in the rodents' reproductive biology: their lack of a germline stem cell niche. In other mammals, germline stem cells are located in a particular area of the body, where they can interact with other essential reproductive cells. Without this location and communication, the mammals' fertility eventually decreases with age. In naked mole-rats, however, there is no such location or communication. As a result, they don't experience the fertility decline seen in other species. The researchers also found that their reproductive cells contain fewer genetic mutations than those of other mammals, likely contributing to the animals' extended fertility. Implications for Humans The findings of this study are exciting and open up new possibilities for humans. Though germline stem cell niches are important in mammalian reproduction, they clearly don't tell the whole story. The lack of one in the naked mole-rats shows that alternative processes may be responsible for extended fertility in other species, including humans. The findings also point to potential new treatments for age-related fertility issues. For example, the study’s authors suggest that improving the communication between reproductive cells – much like that seen in the naked mole-rats – could potentially be used to help humans extend their fertility beyond the natural decline seen in other mammals. Conclusion Though small and often overlooked, naked mole-rats are one of the most remarkable creatures of the animal kingdom. Thanks to a new study from the University of Rochester, we now have a better understanding of the rodents' indefinite fertility. The findings suggest that similar alternative processes could be responsible for extended fertility in other species, including humans. With further research and exploration, scientists could eventually use this knowledge to create new therapies for age-related fertility issues. That’s certainly something to be excited about.

Was Earth already heating up, or did global warming reverse a long-term cooling trend?

The Earth's temperature has been on a dramatic rise for the past century. The effects of this rapid increase in temperature can be felt almost all around the world, from diminished snow and ice cover, to heat waves and coastal flooding. The scientific community has traced the worldwide temperature increase to human activities, particularly the burning of fossil fuels, which has led to a buildup of greenhouse gases such as carbon dioxide and methane in the atmosphere. For the past one hundred years, thermometers and other sophisticated measuring devices have been used to monitor the Earth's climate and temperature. The results have been clear and consistent. According to the National Aeronautics and Space Administration (NASA), the global average surface temperature has risen by 1.8 degrees Fahrenheit (1 degree Celsius) over the past century. This warming has been observed in both land and ocean temperatures. The evidence of this global temperature rise is alarming, but unfortunately it is not surprising. Scientists have long known that the burning of fossil fuels was causing a buildup of greenhouse gases in the atmosphere, trapping heat and rising temperatures around the world. This phenomenon is known as the “greenhouse effect.” The accumulation of these pollutants has been identified as the primary driver of the Earth’s temperature increase. It is important to note that the effects of global warming are not limited to temperature. Perhaps the most visible of global warming’s effects is the melting of snow and ice cover. As temperatures continue to rise due to greenhouse gases, snow and ice cover is diminishing in many areas worldwide. This has far-reaching impacts, from the disruption of Arctic ecosystems, to sea-level rises in coastal areas. Beyond the melting of snow and ice, global warming has been linked to an increase in the frequency of extreme weather events. Heat waves, droughts, floods, hurricanes, and other weather phenomena have all been linked to rising temperatures. Warmer air temperatures can lead to a greater number of extreme weather events, causing further disruption to ecosystems and communities around the world. The scientific community has now largely agreed that human activities – such as the burning of fossil fuels – are the primary driver of global warming. The Earth’s temperature has risen steadily over the past century and the evidence is difficult to dispute. Measuring devices such as thermometers and sensors around the world have confirmed this global temperature rise and the data is alarming. The most visible impact of global warming is the melting of snow and ice cover in many areas around the world. In addition to this, global warming has also been linked to an increase in the frequency of extreme weather events. Heat waves, droughts, floods, hurricanes, and other weather phenomena have all been linked to rising temperatures. The consequences of global warming reach far beyond the disruption of ecosystems and communities around the world. Scientists have warned of the potential for irreversible damage to the planet. Global warming is leading to sea-level rises and has been linked to the acidification of ocean waters, as well as an overall decrease in the world’s biodiversity. Humans must take steps to reduce their contribution to global warming. If we do not act now, the planet could suffer catastrophic and irreversible damage, resulting in a whole host of serious consequences. We must consider the future of the planet and move away from activities that produce greenhouse gases and other pollutants. Reducing our emissions is the only way to prevent further warming of the planet. It is clear that global warming is a serious issue and its impacts cannot be ignored. The Earth’s average temperature has risen by 1 degree Celsius (1.8 degrees Fahrenheit) over the past century, due to the burning of fossil fuels and the accumulation of greenhouse gases in the atmosphere. This rapid temperature increase is leading to the melting of snow and ice cover, sea-level rises, and an overall decrease in the world’s biodiversity. In addition, warmer temperatures have been linked to an increase in extreme weather events, such as heat waves and floods. It is now more important than ever that humans take action to reduce emissions and move away from activities that produce greenhouse gases and other pollutants. We must consider the future of the planet and take steps to reduce the impacts of global warming. If we are to avoid catastrophic and irreversible damage to the planet, we must act now.

Lonely tunes: Humpback whales wail less as population grows

Humpback whales are some of the most impressive and majestic creatures of the sea, known for their haunting and melodic songs that can often be heard echoing throughout the depths of the ocean. However, what is not commonly known is that these songs may actually be a sign of loneliness experienced by the whales. Recent research has shown that these beautiful songs may be a primal instinctive response to a lack of companionship for the humpbacks. It is thought that when a whale does not have a suitable social group with which to swim and interact, they release a plaintive song into the watery depths in search of other whales and a sense of belonging. This hypothesis was initially put forward by researchers studying the behavior of several groups of humpbacks in the Pacific Ocean. Upon observation, it was noted that when an isolated whale was encountered, its song was much more plaintive and melancholic than the songs sung by whales who had companions. Over time, the scientists noted a correlation between the songs and the social dynamics of the humpbacks – those who were alone had the saddest and most plaintive songs, while those who were in the presence of social groups had happier and more lively songs. Although the activities of whales are still not fully understood, it is likely that the melancholic tunes sung by lone humpbacks can be seen as a sign of loneliness. For many of these remarkable creatures, the need for companionship is as strong as that of any social animal, and their songs may simply be a form of communication to help them in their search for companionship. In further support of this idea, recent studies of other whale species have produced similar results. For example, a study of blue whales in the Pacific revealed that the songs of the isolated whales were much sadder and more plaintive than their counterparts who were with their pods. This suggests that loneliness is not only an issue for humpbacks but for other whale species too. Although the research into the melancholy songs sung by whales is still in its early stages, the observations made by the scientists go some way to explaining the songs of the humpbacks. It is thought that the whales use their plaintive tunes as a way to connect with their own kind and to draw attention to their plight. Despite the melancholy nature of these tunes, it is also a reminder of the importance of companionship among the whale species. It demonstrates that, regardless of species, social connection is a key factor in the happiness of animals. These remarkable creatures should serve as a reminder to us all of the importance of connecting with others and the need for companionship.

Climate modelers add ocean biogeochemistry and fisheries to forecasts of future upwelling

A handful of hyper-productive fisheries provide sustenance to a billion people and employ tens of millions. These fisheries occur on the eastern edges of the world's oceans—off the West Coast of the U.S., the Canary Islands, Peru, Chile, and Benguela. There, a process called upwelling brings cold water and nutrients to the surface, which in turn supports large numbers of larger sea creatures that humans depend on for sustenance.

CRISPR-based strategy restores neurons affected by Rett syndrome

Rett syndrome is a rare, progressive neurodevelopmental disorder that typically affects girls, causing severe intellectual disability, loss of motor skills, and autism-like symptoms, and there is currently no cure. Rett syndrome is caused by a loss-of-function mutation in the X chromosome gene MECP2. Females typically have two copies of MECP2—one on each X chromosome—and in most cases of Rett syndrome, only one copy has the mutation. The disease occurs because the other, normal copy of MECP2 is turned off in neurons by a process called X chromosome inactivation.

Commonly used antiretroviral drugs used to treat HIV and hepatitis B reduce immune cells' energy production

New UCLA-led research suggests that antiretroviral drugs called TAF and TDF directly reduce energy production by mitochondria, structures inside cells that generate the power that cells use to function. Both drugs led to reduced cellular oxygen consumption rates, a measure of the ability of the mitochondria to produce energy, compared with controls. But in combination with other antiretrovirals, TAF appeared to result in a larger energy reduction than TDF did. Whether this is a cause for concern is not known at this point.

Riddle solved: Why was Roman concrete so durable?

The ancient Romans were masters of engineering, constructing vast networks of roads, aqueducts, ports, and massive buildings, whose remains have survived for two millennia. Many of these structures were built with concrete: Rome's famed Pantheon, which has the world's largest unreinforced concrete dome and was dedicated in A.D. 128, is still intact, and some ancient Roman aqueducts still deliver water to Rome today. Meanwhile, many modern concrete structures have crumbled after a few decades.

Development of standardized tests for assessing lidars in autonomous vehicles

Today, autonomous vehicles (AVs) and advanced driver assistance systems (ADASs) are rapidly growing research avenues aimed at increasing vehicle and road safety. Both technologies minimize human error by enabling cars to "perceive" their surroundings and act accordingly. This is achieved using light detection and ranging (lidar) technology, one of the most important and versatile components in AVs. Lidars provide a three-dimensional map of all objects around the vehicle regardless of external lighting conditions. This map, updated hundreds of times per second, can be used to estimate the position of the vehicle relative to its surroundings in real time.

Researchers uncover how embryonic cells sense their mechanical environment to collectively form tissues

Building tissues and organs is one of the most complex and important tasks that cells must accomplish during embryogenesis. Individual cells do not make these decisions; rather, building tissue is a collective task that requires cells to constantly communicate with each other. Different communication methods exist, including chemical cues, similar to a cell's sense of smell, and also mechanical cues, the cell's sense of touch. Researchers in a variety of fields have been fascinated by cell communication for decades and have discovered how cells use biochemical cues for that purpose. However, how cells use their sense of touch to make decisions during embryogenesis is still a mystery.

Tipping points complicate the evaluation of complex climate models

An analysis by Robbin Bastiaansen and Anna von der Heydt, the University of Utrecht, the Netherlands; and Peter Ashwin, the University of Exeter, UK, indicates that it might remain difficult to accurately find the equilibrium climate sensitivity in complex climate models. The equilibrium climate sensitivity is used to compare and evaluate models and is calculated using a limited set of data from a relatively short simulation. But such results could be heavily underestimating long-term warming as late climate tipping cannot be excluded by the commonly used methods to estimate equilibrium climate sensitivity, conclude the authors. The work is part of the European TiPES project on tipping points in the Earth system.

Good hydration linked to healthy aging

Adults who stay well-hydrated appear to be healthier, develop fewer chronic conditions, such as heart and lung disease, and live longer than those who may not get sufficient fluids, according to a National Institutes of Health study published in eBioMedicine.     Using health data gathered from 11,255 adults over a 30-year period, researchers analyzed links between serum sodium levels—which go up when fluid intake goes down—and various indicators of health. They found that adults with serum sodium levels at the higher end of a normal range were more likely to develop chronic conditions and show signs of advanced biological aging than those with serum sodium levels in the medium ranges. Adults with higher levels were also more likely to die at a younger age.
