- 20/7/2 21:37
As many as 7% of moms-to-be use marijuana while pregnant, and that number is rising fast as more use it to quell morning sickness. But new research suggests such use could have a lasting impact on the fetal brain, influencing children's sleep for as much as a decade.
Research reflects how AI sees through the looking glass
- ScienceDaily
- 20/7/2 21:24
Intrigued by how reflection changes images in subtle and not-so-subtle ways, a team of researchers used artificial intelligence to investigate what sets originals apart from their reflections. Their algorithms learned to pick up on unexpected clues such as hair parts, gaze direction and, surprisingly, beards - findings with implications for training machine learning models and detecting faked...

In a new meta-study, experts have published ground-breaking findings on the effects of climate change for fish stock around the globe.
How the body fights off urinary tract infections
- ScienceDaily
- 20/7/2 20:47
Some people are better protected than others against urinary tract infections. This may be because their bodies produce more of a protein called uromodulin. An interdisciplinary research team has now found out exactly how this helper protein brings relief when nature calls and how this knowledge might benefit the treatment and prevention of these painful inflammations.
Why are the offspring of older mothers less fit to live long and prosper?
- ScienceDaily
- 20/7/2 20:41
In a new study in rotifers (microscopic invertebrates), scientists tested the evolutionary fitness of older-mother offspring in several real and simulated environments, including laboratory culture, under threat of predation in the wild, or with reduced food supply. They confirmed that this effect of older maternal age, called maternal effect senescence, does reduce evolutionary fitness of the...
Sniffing out smell: How the brain organizes information about odors
- ScienceDaily
- 20/7/2 20:41
Neuroscientists describe for the first time how relationships between different odors are encoded in the brain. The findings suggest a mechanism that may explain why individuals have common but highly personalized experiences with smell, and inform efforts better understand how the brain transforms information about odor chemistry into the perception of smell.
New light-based method for faster and 'green' production of building blocks for medicines
- ScienceDaily
- 20/7/2 20:41
Researchers have developed a new method to convert gaseous, low-weight hydrocarbons into more complex molecules by illuminating the hydrocarbons with light in the presence of a suitable catalyst.
Grassroots dog vaccinations can help stop rabies, but not alone
- ScienceDaily
- 20/7/2 20:41
While scientists are trying to find a vaccine for COVID-19, the rabies virus continues to kill 59,000 people every year. But unlike COVID, a vaccine has existed for more than a century. Vaccinating dogs can stop the spread to humans, but systemic challenges make that easier said that done. In a new study, scientists where grassroots campaigns to stop rabies work -- and where they need to be...
Anaplasmosis bacterium tinkers with tick's gene expression to spread to new hosts
- ScienceDaily
- 20/7/2 20:41
For the first time, scientists have shown that the bacterium that causes the tick-borne disease anaplasmosis interferes with tick gene expression for its survival inside cells and to spread to a new vertebrate host.
New method measures temperature within 3D objects
- ScienceDaily
- 20/7/2 20:41
Engineers have made it possible to remotely determine the temperature beneath the surface of certain materials using a new technique they call depth thermography. The method may be useful in applications where traditional temperature probes won't work, like monitoring semiconductor performance or next-generation nuclear reactors.
Moss protein corrects genetic defects of other plants
- ScienceDaily
- 20/7/2 20:40
Almost all land plants employ an army of molecular editors who correct errors in their genetic information. Researchers have now transferred one of these proofreaders from the moss Physcomitrium patens (previously known as Physcomitrella patens) into a flowering plant. Surprisingly, it performs its work there as reliably as in the moss itself.
