When a chromosome is lost: How do human cells react to monosomy?
Human cells are usually diploid—they contain two sets of chromosome. Cells in which one chromosome is missing from the duplicated chromosome set are generally not viable. For a long time, the mechanisms responsible for the loss of viability were un.....»»
Chemists introduce new copper-catalyzed C-H activation strategy
Inspired by what human liver enzymes can do, Scripps Research chemists have developed a new set of copper-catalyzed organic synthesis reactions for building and modifying pharmaceuticals and other molecules. The new reactions are expected to be widel.....»»
Uncovering key players in gene silencing: Insights into plant growth and human diseases
Monash University biologists have shed light on the intricate molecular mechanisms that are responsible for gene silencing induced by expanded repeats in an international study published today in Nature Plants......»»
Why zebrafish can regenerate damaged heart tissue, while other fish species cannot
A heart attack will leave a permanent scar on a human heart, yet other animals, including some fish and amphibians, can clear cardiac scar tissue and regrow damaged muscle as adults......»»

AuditBoard expands executive team to support the next phase of growth
AuditBoard announced it has brought on public SaaS company veteran Jeff Harper as Chief Human Resources Officer (CHRO) to help scale the organization and infrastructure, continue to attract and retain exceptional talent, and steward AuditBoard’s aw.....»»
Light show in living cells: New method allows simultaneous fluorescent labeling of many proteins
Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge—especially in living cells, as the required fluorescent labeling had to be individually attached to each p.....»»
Key protein regulates immune response to viruses in mammal cells
Researchers have revealed the regulatory mechanism of a specific protein that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and.....»»
Cyberattack on key parts supplier triggered dispute that cost Stellantis $300M, lawsuit says
The automaker lost more than $300 million in revenue because it was unable to manufacture 6,000 vehicles without parts from Yanfeng, the lawsuit says......»»
CEOs" human concern translates into higher stock price, says study
Compassionate leadership has tangible benefits: CEOs' expressions of empathy correlate with positive stock performance, a study led by the University of Zurich shows. The researchers analyzed data from conference calls between CEOs and financial anal.....»»
First evidence of ancient human occupation found in giant lava tube cave in Saudi Arabia
If you look from above, you can see thousands of stone structures dotting the landscape of the Arabian peninsula. On the ground, you can find a bounty of stone tools and ancient fireplaces scattered along the edges of ancient lakes, as well as rock a.....»»
Bird flu in cattle: What are the concerns surrounding the newly emerging bovine H5N1 influenza virus?
The confirmed presence of bird flu in American dairy cattle in a March 25 report from the U.S. Department of Agriculture (USDA)—and a case in Texas where a human working with cattle was infected—has put Canadian public health experts on high aler.....»»
Researchers crack mystery of swirling vortexes in egg cells
Egg cells are the largest single cells on the planet. Their size—often several to hundreds of times the size of a typical cell—allows them to grow into entire organisms, but it also makes it difficult to transport nutrients and other molecules ar.....»»
"Human-induced" climate change behind deadly Sahel heat wave: Study
The deadly heat wave that hit Africa's Sahel region in early April would not have occurred without human-induced climate change, according to a study by the World Weather Attribution (WWA) group published Thursday......»»
Mobile genetic elements can inadvertently suppress bacterial immune systems, research reveals
Bacterial restriction-modification systems are responsible for protecting cells from foreign genetic material, for example, bacteriophages and plasmids. Immune systems require strict regulation, as bacteria, like humans, can have autoimmune reactions.....»»
Scientists grow human mini-lungs as animal alternative for nanomaterial safety testing
Human mini-lungs grown by University of Manchester scientists can mimic the response of animals when exposed to certain nanomaterials. The study is published in Nano Today......»»
Researchers identify genetic variant that helped shape human skull base evolution
Humans, Homo sapiens, have unique features compared with other closely related hominin species and primates, including the shape of the base of the skull. The evolutionary changes underlying these features were significant in allowing the evolution o.....»»
Bodies found in Neolithic pit were likely victims of ritualistic murder
