Study explores link between shark nose shape, size and sensitivity of smell
Sharks have reputations as "super smellers" that use olfaction to detect odors related to finding prey and mates, communicating with their own species and avoiding predators. Their olfactory system is unique because it is separate from the respirator.....»»
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.....»»
Researchers investigate three star-forming regions, identify hundreds young stellar objects
Using data from various space telescopes and astronomical surveys, Armenian researchers have investigated three star-forming regions. The study identified hundreds of young stellar objects and provided important information regarding the stellar cont.....»»
Capturing DNA origami folding with a new dynamic model
Most people are familiar with the DNA double-helix. Its twisted ladder shape forms because the long pieces of DNA that make up our genome are exactly complementary—every adenine paired to a thymine, and every cytosine paired to a guanine. Sequences.....»»
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......»»
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......»»
El Nino not climate change driving southern Africa drought: Study
A drought that pushed millions of people into hunger across southern Africa has been driven mostly by the El Niño weather pattern—not climate change, scientists said on Thursday......»»
Mind the gender gap: Study finds London police least trusted by women
Across all England's regions, a study appearing in the journal Policing & Society spotlights London's Metropolitan Police as the area where women trust the least......»»
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.....»»
Two-dimensional nanomaterial sets expansion record
It is a common hack to stretch a balloon out to make it easier to inflate. When the balloon stretches, the width crosswise shrinks to the size of a string. Noah Stocek, a Ph.D. student collaborating with Western physicist Giovanni Fanchini, has devel.....»»
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.....»»
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.....»»
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.....»»
The Aral Sea has made Central Asia significantly dustier, according to study
The drying up of the Aral Sea has made Central Asia 7% dustier in the last 30 years. Between 1984 and 2015, dust emissions from the growing desert almost doubled from 14 to 27 million tons. This is the result of a study by the Leibniz Institute for T.....»»
Peptides on interstellar ice: Study finds presence of water molecules not a major obstacle for formation
A research team led by Dr. Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles. However, it was previo.....»»
In life cycle diagrams, small changes make a big difference
Life cycle diagrams are ubiquitous in science textbooks, and they may be due for some updates. A new study finds simple design changes in these diagrams can have a dramatic impact on the ability of undergraduate students to understand key biology con.....»»
Study shows copper beads in pig feed reshape swine gut microbiome
Copper is a natural antimicrobial material that, when added to pig feed, may promote the growth and health of the animals. Since pigs can tolerate high levels of the metal, researchers at Texas Tech University in Amarillo recently investigated whethe.....»»
