Ocean waves propel PFAS back to land

Science Daily - 06/04/2024
A new study reveals that PFAS re-emit into the air from crashing ocean waves at levels comparable to or greater than other sources, establishing a cyclical transport process for these 'forever chemicals' between land and sea.

Atlas of the human ovary with cell-level resolution is a step toward artificial ovary

Science Daily - 06/04/2024
A new 'atlas' of the human ovary provides insights that could lead to treatments restoring ovarian hormone production and the ability to have biologically related children, according to engineers.

A simple, inexpensive way to make carbon atoms bind together

Science Daily - 06/04/2024
The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon -- a carbon atom bonded to four other carbon atoms. But now, scientists have uncovered a potential cost-effective way to produce these tricky motifs.

In the evolution of walking, the hip bone connected to the rib bones

Science Daily - 06/04/2024
A new reconstruction of the 375-million-year-old fossil fish Tiktaalik -- a close relative of limbed vertebrates -- used micro-CT to reveal bones still embedded in matrix. The reconstruction shows that the fish's ribs likely attached to its pelvis, an innovation thought to be crucial to supporting the body and for the eventual evolution of walking.

Innovative sensing platform unlocks ultrahigh sensitivity in conventional sensors

Science Daily - 06/04/2024
Engineers unlock the power of exceptional points (EPs) for advanced optical sensing. EPs -- specific conditions in systems where extraordinary optical phenomena can occur -- can be deployed on conventional sensors to achieve a striking sensitivity to environmental perturbations.

Dinosaur study challenges Bergmann's rule

Science Daily - 06/04/2024
A new study calls into question Bergmann's rule, an 1800s-era scientific principle stating that animals in high-latitude, cooler climates tend to be larger than close relatives living in warmer climates.

Common loons threatened by declining water clarity

Science Daily - 06/04/2024
The Common Loon, an icon of the northern wilderness, is under threat from climate change due to reduced water clarity, according to a new study. The study followed up an earlier paper that showed substantial reproductive decline in the author's study area in northern Wisconsin.

Can language models read the genome? This one decoded mRNA to make better vaccines

Science Daily - 06/04/2024
Researchers developed a foundational language model to decode mRNA sequences and optimize those sequences for vaccine development. The tool shows broader promise as a means for studying molecular biology.

First tandem repeat expansions genetic reference maps

Science Daily - 06/04/2024
A research team has built a genetic reference maps for short lengths of DNA repeated multiple times which are known to cause more than 50 lethal human diseases, including amyotrophic lateral sclerosis, Huntington's disease and multiple cancers.

eDNA methods give a real-time look at coral reef health

Science Daily - 06/04/2024
The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.

Chemical reactions can scramble quantum information as well as black holes

Science Daily - 05/04/2024
A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and testing their theory in chemical reactions.

A deep dive into the genetics of alcohol consumption

Science Daily - 05/04/2024
Some people have genes that protect them from alcohol abuse. An examination of databases at 23andMe reveal that those same alcohol-protective variants have associations with conditions and behaviors that may have nothing to do with alcohol.

Heat stress from ocean warming harms octopus vision

Science Daily - 05/04/2024
While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.

Rapid, simultaneous detection of multiple bacteria achieved with handheld sensor

Science Daily - 05/04/2024
A team has developed a method for simultaneous detection of multiple disease-causing bacterial species within one hour using a handheld device.

The sense of smell is influenced by cues from other senses

Science Daily - 05/04/2024
The sense of smell is highly influenced by the cues from other senses, while the sense of sight and hearing are affected to a much lesser extent, shows a new study.

RNA that doesn't age

Science Daily - 05/04/2024
Certain RNA molecules in the nerve cells in the brain last a life time without being renewed. Neuroscientists have now demonstrated that this. RNAs are generally short-lived molecules that are constantly reconstructed to adjust to environmental conditions. The research group hopes to decipher the complex aging process of the brain and gain a better understanding of related degenerative diseases.

Astronomy: How do brown dwarfs form?

Science Daily - 05/04/2024
New observations provide insights into whether the birth of the giant planets takes a similar course to that of stars.

Four in five bird species cannot tolerate intense human pressures

Science Daily - 05/04/2024
In a recent study, researchers found that 78% of the world's bird species do not thrive in the most modified human-dominated environments. These species are also most likely to have declining populations.

Functional capacity in old age is like an ecosystem that may collapse when disrupted

Science Daily - 05/04/2024
In old age, a tighter interlinkage between different domains of functional capacity may indicate a loss of system resilience. When functional capacity domains are tightly interconnected, a disruption in one domain can affect others and lead to a collapse in functioning. It is therefore important to look at functioning as a whole and to take care of the different aspects of physical and mental well-being.
