A new study describes a bioluminescent gene that could be the reason that so-called "sea pickles," or pyrosomes, an underwater free-floating colony of thousands of tiny animals, reverberate in blue-green light. If confirmed, the finding would be the first bioluminescent gene identified from a chordate--the group that includes all vertebrates as well as a couple types of invertebrates: sea squirts (including pyrosomes) and lancelets. The research is published today in the journal Scientific Reports.
Researchers at McMaster University have found distinct effects of adversity early in life in the genomes of men compared to women who were born extremely preterm.
The study, published online in the journal Development and Psychopathology, followed infants who weighed between 580 and 1000 grams at birth. The cohort was initiated by Saroj Saigal in the Department of Pediatrics in the late 1970's and has been prospectively followed over four decades.
A paleoseismic trench dug across the Gales Creek fault, located about 35 kilometers (roughly 22 miles) west of Portland, Oregon, documents evidence for three surface-rupturing earthquakes that took place about 8,800, 4,200 and 1,000 years ago.
A chip-based technology that generates sound profiles with high resolution and intensity could create new options for ultrasound therapy, which would become more effective and easier. A team of researchers led by Peer Fischer from the Max Planck Institute for Intelligent Systems and the University of Stuttgart has developed a projector that flexibly modulates three-dimensional ultrasound fields with comparatively little technical effort. Dynamic sound pressure profiles can thus be generated with higher resolution and sound pressure than the current technology allows.
HOUSTON - (Oct. 19, 2020) - U.S. and Italian engineers have demonstrated the first nanophotonic platform capable of manipulating polarized light 1 trillion times per second.
"Polarized light can be used to encode bits of information, and we've shown it's possible to modulate such light at terahertz frequencies," said Rice University's Alessandro Alabastri, co-corresponding author of a study published this week in Nature Photonics.
COLUMBUS, Ohio - Humans aren't born with mature brain circuitry that attaches emotions to the things they see or hear in their environment, a new study shows.
Researchers studying brain scans of newborns found that the part of the brain involved in experiencing emotions isn't functionally connected in a mature way with the regions that process visual or auditory stimuli.
In adults, the connections between those parts of the brain allow us to feel fear when we see a bear in the woods or love when we see the face of a family member.
Rocks from the Rio Grande continental rift have provided a rare snapshot of active geology deep inside Earth's crust, revealing new evidence for how continents remain stable over billions of years, according to a team of scientists.
The number of sea turtles spotted along the coasts of the UK and Ireland has declined in recent years, researchers say.
University of Exeter scientists studied records going back more than a century (1910-2018) and found almost 2,000 sea turtles had been sighted, stranded or captured.
Recorded sightings increased dramatically in the 1980s and 1990s - possibly due to more public interest in conservation, and better reporting schemes.
Numbers have dropped since 2000, but the reasons for this are unclear.
Krill is rapidly gaining popularity. The small shrimp-like organism from the Antarctic is used as fish food in aquaculture and increasingly in dietary supplements and healing ointments. Although the krill catch is regulated, caution is required to avoid endangering the population itself and the species that depend on it, warns a group of krill experts headed by Prof. Dr. Bettina Meyer from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) in the journal Communications Earth & Environment - Nature.
In his quest to bring ever-faster cameras to the world, Caltech's Lihong Wang has developed technology that can reach blistering speeds of 70 trillion frames per second, fast enough to see light travel. Just like the camera in your cell phone, though, it can only produce flat images.
FRANKFURT. In 1999, the Egyptian chemist Ahmed Zewail received the Nobel Prize for measuring the speed at which molecules change their shape. He founded femtochemistry using ultrashort laser flashes: the formation and breakup of chemical bonds occurs in the realm of femtoseconds. A femtosecond equals 0.000000000000001 seconds, or 10 exp -15 seconds.
Oncotarget Volume 11, Issue 29 reported that In multivariate analyses, serum albumin, GNRI, pathological tumor-node-metastasis stage, and tumor differentiation were independent prognostic factors for CSS.
In pTNM stage I, multivariate analysis identified C-reactive protein and GNRI as independent prognostic factors for CSS.
Palo Alto, CA-- In a changing climate, understanding how organisms respond to stress conditions is increasingly important. New work led by Carnegie's Arthur Grossman and Emanuel Sanz-Luque could enable scientists to engineer the metabolism of organisms to be more resilient and productive in a range of environments.
While much attention has been paid to the increasing prevalence of autism spectrum disorder (ASD) among U.S. children and adolescents, less is known about the population of adults with ASD. Medicaid is an important health care coverage provider for individuals with autism, including adults. Using administrative data from the Medicaid Analytic eXtract (MAX), researchers from Drexel University's A.J.
Scientists in Australia have stumbled across an unusual way to observe colour that had previously gone unnoticed.
To create the effect, researchers attached a very thin film of one material to another, larger sample. The electric field (an invisible force created by the attraction and repulsion of electrical charges) is very strong where the two materials are connected.
