Sexual parasitism helped anglerfish invade the deep sea during a time of global warming
2024-05-23
Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers reporting in the journal Current Biology on May 23 show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.
The findings have implications for understanding evolution and the effects that global warming may have in the deep sea, according to the researchers.

Archaeology: Differences in Neanderthal and Palaeolithic human childhood stress
2024-05-23
Neanderthal children (who lived between 400,000 and 40,000 years ago) and modern human children living during the Upper Palaeolithic era (between 50,000 and 12,000 years ago) may have faced similar levels of childhood stress but at different developmental stages, according to a study published in Scientific Reports. The authors suggest that these findings could reflect differences in childcare and other behavioural strategies between the two species.
Laura Limmer, Sireen El Zaatari and colleagues analysed the dental enamel of 423 Neanderthal teeth (from 74 Homo neanderthalensis individuals) and 444 Upper Palaeolithic humans (from 102 Homo sapiens ...
Rising temperatures will significantly reduce streamflow in the upper Colorado river basin as groundwater levels fall, new research shows
2024-05-23
The Colorado River makes life possible in many Western cities and supports agriculture that sustains people throughout the country. Most of the river’s water begins as snowmelt from the mountainous watersheds of Colorado, Utah, and Wyoming, and a warming climate will drastically reduce these streamflows, new research finds.
Researchers from Desert Research Institute (DRI), USGS, and Lawrence Berkeley National Laboratory teamed up for the new study, published May 23 in Nature Water. By applying warming to historical conditions for the East River in Colorado and using computer simulations to observe the impact on streamflow and groundwater ...
Prenatal exposure to chemical mixtures and metabolic syndrome risk in children
2024-05-23
About The Study: The findings of this cohort study suggest that prenatal exposure to endocrine-disrupting chemical mixtures may be associated with adverse metabolic health in children.

Exposure to mixtures of endocrine-disrupting chemicals during pregnancy is associated with higher odds of metabolic syndrome in children
2024-05-23
The term ‘metabolic syndrome’ (MetS) encompasses a group of factors, such as abdominal obesity, hypertension and insulin resistance, that together increase the risk of cardiovascular disease and type 2 diabetes. A new study suggests that prenatal exposure to a combination of endocrine disrupting chemicals (EDCs) is associated with a poorer metabolic health in childhood, which in turn may contribute to an increased risk of metabolic syndrome in adulthood. The research, led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, has been published in JAMA Network Open.

Sea of love: Behind the unusual sexual parasitism of deep-water anglerfishes
2024-05-23
New Haven, Conn. – As the planet’s most expansive ecosystem, the deep sea can be a tough place to find a mate. Though, scientists say, some deep-sea anglerfishes evolved a unique method of reproduction that ensures that once they land a partner in the vast open waters, they remain latched for life.
These anglerfishes, called ceratioids, reproduce through sexual parasitism, in which the tiny males attach to their much larger female counterparts to mate. In some species, the males bite the females ...

YouTubers cheer people up more than casual friends
2024-05-23
One-sided relationships with YouTubers are more emotionally fulfilling than talking to casual friends, a new study suggests.
The University of Essex research discovered people feel watching online stars like Zoella, KSI and PewDiePie can cheer them up more than weak-tie acquaintances – like neighbours or co-workers.
Dr Veronica Lamarche, from the Department of Psychology, also found people feel liked, respected and understood by fictional characters.
The study suggests watching online celebrities offer positive reinforcement - despite them not being able to respond.

Earth twin or evil twin
2024-05-23
The discovery of a planet similar to Venus around a star in the neighborhood of the Solar System raises hopes that astronomers may someday unlock the secret to why life appeared on Earth.
The study of life in the Universe is difficult because we have only one example of a planet where life has been confirmed: Earth. It is difficult to say which characteristics of Earth are required for life to appear, and which are irrelevant. Until we find an “Earth twin” where the conditions for life also appeared, the best astronomers ...
Tracking down the genetic causes of lupus to personalize treatment
2024-05-23
Lupus is a lifelong, often painful and occasionally lethal autoimmune disease. Few treatments exist today beyond powerful steroids to knock down a patient's immune system — a therapy that has its own serious risks.
The good news is that new and promising treatments are in clinical trials. But the term lupus belies the fact that the disease has a variety of causes, which means that treatments will have to be highly personalized to guarantee that each patient is given the drug that targets the specific genetic mutation ...
New discoveries about the nature of light could improve methods for heating fusion plasma
2024-05-23
Both literally and figuratively, light pervades the world. It banishes darkness, conveys telecommunications signals between continents and makes visible the invisible, from faraway galaxies to the smallest bacterium. Light can also help heat the plasma within ring-shaped devices known as tokamaks as scientists worldwide strive to harness the fusion process to generate green electricity.
Now, scientists have made discoveries about light particles known as photons that could aid the quest for fusion ...
Lehigh University researchers explore innovative cable-based approach to aerial robotics
2024-05-23
When we think about drones, we tend to think about Amazon. But their potential is much greater, and arguably far more important, than dropping off a box of laundry pods by lunchtime (an idea that’s struggled to take off since Jeff Bezos floated it more than a decade ago).
Aerial robots could be a huge asset, saving time, money, and workers’ well-being, in industries like construction where humans often have to heft materials up multiple floors, says David Saldaña, an assistant professor of computer science and engineering. They could also deliver ...

How family economic insecurity can hurt child mental health
2024-05-23
COLUMBUS, Ohio – Economic difficulty caused by the COVID-19 pandemic led to a cascade of connected problems for some parents – resulting in mental health problems for their children, a new study suggests.
Researchers found that economic insecurity was linked to higher levels of depressive symptoms for parents, which was then associated with poorer relationship quality for the couples. That was linked with more harsh parenting and then to increased internalizing behaviors for their children.

Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought to the disturbances from humans
2024-05-23
Summer is coming and that means more boats in the sea. Danish coastal waters are especially cluttered with small boats in the summertime. Locals water skiing, going fishing or just riding around the beautiful bays and fjords.
In general people relax and have a good time on the water, but that is unfortunately not the case for the harbor porpoise.
The more motor boats speeding noisily around, the more they are disturbed. And that can be a big problem for the animals.
Because the harbor porpoise is a relatively large animal that feeds on small fish it needs to spend a lot of time hunting. New research shows that it spends around 60 percent of its time on the hunt, but ...
