New method boosts the study of regulation of gene activity
One way cells can control the activities of their genes is by adding small chemical modifications to the DNA that determine which genes are turned on or off. Methyl groups are one of these chemical modifications or tags. Researchers have found that i.....»»
The effects of climate variability on children"s migration and childcare practices in sub-Saharan Africa

Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation
Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species due to its redox inertnes.....»»
Amazonia"s fire crises: Emergency fire bans insufficient, strategic action needed before next burning season
In response to the escalating fire crises in the Amazon, a timely study has revealed alarming shortcomings in the emergency fire bans implemented by the Brazilian Government. Initially seen as a promising solution in 2019, these bans have consistentl.....»»
Researchers reveal a hidden trait in Mycobacterium genomes governing stress adaptation
A new study, led by Qingyun Liu, Ph.D., assistant professor in the Department of Genetics, has uncovered a genetic feature known as "transcriptional plasticity," which plays a pivotal role in governing the transcriptional response of Mycobacteria to.....»»
"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

Study examines influence of social media on televised debate viewing
Anyone who regularly watches news or sports has likely noticed the steady creep of content competing for screen space, whether it be stock market prices, social media posts, game scores or some other graphic display. Previous studies have indicated t.....»»
Global study reveals health impacts of airborne trace elements
As anyone with seasonal allergies knows, unseen airborne particles can really wreck a person's day. Like the tree pollen that might be plaguing you this spring, small concentrations of trace elements in the air can have significant negative impacts o.....»»
Current police response to intimate partner violence calls for change, researchers say
Policing of intimate partner violence (IPV) may result in adverse consequences for survivors, according to a new study at Columbia University Mailman School of Public Health. However, the evidence concerning the generalized consequences of IPV polici.....»»
Soil bacteria link their life strategies to soil conditions: Study
Soil bacteria help regulate the cycling of carbon and nutrients on Earth. Over time, these bacteria have evolved strategies that determine where they live, what they do, and how they deal with a changing environment. However, microbiologists do not f.....»»
Climate damages by 2050 will be 6 times the cost of limiting warming to 2°
Study tracks the past costs of climate events and projects them into the future. Enlarge (credit: Frame Studio) Almost from the start, arguments about mitigating climate change have included an element of cost-benefit an.....»»
