Observing the birth of a quasiparticle
Over the past decades, physicists worldwide have been trying to gain a better understanding of non-equilibrium dynamics in quantum many-body systems. Some studies investigated what are known as quasiparticles, disturbances or entities in physical sys.....»»
Preemie boys age faster as men, study shows
Using an epigenetic clock, the researchers looked at the genes of 45 of those who were ELBW babies along with 47 who were normal birth weight when they were age 30 to 35 to compare their biological age, controlling for chronic health problems and sen.....»»
Observing eco farmers could guide sustainable information technology innovation
Cutting-edge agricultural technology has advanced in recent years, introducing innovations from self-driving tractors and laser scarecrows to robotic bees that aid in pollination......»»
Maternal stress during pregnancy may shorten lifespans of male lizard offspring
Mother fence lizards that experience stress during pregnancy give birth to male offspring with shortened telomeres, or bits of non-coding DNA that cap the ends of chromosomes, according to a Penn State-led study. Shorter telomeres are associated with.....»»
Largest-ever study of artificial insemination in sharks—and the occasional "virgin birth"
It's a tough time to be a shark. Pollution, industrialized fishing, and climate change threaten marine life, and the populations of many top ocean predators have declined in recent years. In addition to studying sharks in the wild, scientists working.....»»
Bacteria do not colonize the gut before birth
Researchers examined prenatal stool (meconium) samples collected from 20 babies during breech Cesarean delivery. By including only breech caesarean deliveries in healthy pregnant women they were able to avoid the transmission of bacteria that occurs.....»»
Observing individual atoms in 3D nanomaterials and their surfaces
Atoms are the basic building blocks for all materials. To tailor functional properties, it is essential to accurately determine their atomic structures. KAIST researchers observed the 3D atomic structure of a nanoparticle at the atom level via neural.....»»
Seeing colleagues succeed may make us feel more motivated
Observing the success of a colleague can motivate us to learn more and perform at a higher level. But when we perceive that a peer's accomplishment has risen above the usual standard of "good work" and can be rated an "exceptional" success, our motiv.....»»
A deeper understanding of how cells move and stick together
Observing how cells stick to surfaces and their motility is vitally important in the study of tissue maintenance, wound healing and even understanding how cancers progress. A new paper published in The European Physical Journal Plus, by Raj Kumar Sad.....»»
The Apple Watch proves helpful during surprise mid-flight birth
As if giving birth on a flight isn't unusual enough, Lavinia Mounga didn't even realize she was pregnant, making her trip from Salt Lake City to Honolulu on April 28 particularly memorable. AppleInsider reports that Mounga was lucky in that a physici.....»»
Greater access to birth control leads to higher graduation rates
When access to free and low-cost birth control goes up, the percentage of young women who leave high school before graduating goes down by double-digits, according to a new CU Boulder-led study published May 5 in the journal Science Advances......»»
Using cosmic-ray neutron bursts to understand gamma-ray bursts from lightning
Analysis of data from a lightning mapper and a small, hand-held radiation detector has unexpectedly shed light on what a gamma-ray burst from lightning might look like—by observing neutrons generated from soil by very large cosmic-ray showers. The.....»»
Deciphering the lives of double neutron stars in radio and gravitational wave astronomy
Scientists from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) have described a way to determine the birth population of double neutron stars—some of the densest objects in the universe formed in collapsing massive stars. Th.....»»
Transient grating spectroscopy with ultrafast X-rays
Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in looking inside materials using the method of transient grating spectroscopy with ultrafast X-rays at SwissFEL. The experiment at PSI is a milestone in observing proce.....»»
Childbirth versus pelvic floor stability
Human childbirth is comparatively difficult because our babies' heads are large relative to our birth canals. This tight 'fetopelvic' fit increases the risk of obstructed labor, which in turn has potentially dire outcomes for both mother and child. I.....»»
"Yellowballs" offer new insights into star formation
A serendipitous discovery by citizen scientists has provided a unique new window into the diverse environments that produce stars and star clusters, revealing the presence of "stellar nurseries" before infant stars emerge from their birth clouds, acc.....»»
Study shows multiple factors shape timing of birth in mule deer
A five-year study of mule deer does and newborn fawns in western Wyoming shows that migrating deer have a lot to balance when it comes to birth timing......»»
Baby elephant dies rejected by family at Swedish zoo
A two-week old elephant has died after being rejected by her family following the birth of another elephant calf, Sweden's Boras Zoo announced Friday......»»
Dogs act jealously even when they don"t see their rival
Past surveys have shown that more than 80% of dog owners report observing jealous behaviors from their dogs—vocalizations, agitated behavior, pulling on a leash—when they give attention to other dogs. New research published in the journal Psychol.....»»
Births among endangered right whales highest since 2015
North Atlantic right whales gave birth over the winter in greater numbers than scientists have seen since 2015, an encouraging sign for researchers who became alarmed three years ago when the critically endangered species produced no known offspring.....»»
Curved plasmonic fluxes reveal new way to practical light manipulation within nanoscal
Scientists from Tomsk Polytechnic University jointly with Russian colleagues and researchers from Technical University of Denmark the first time have experimentally proved the existence of a two-dimensional (2D) curved flux of plasmonic quasiparticle.....»»
