Sexual inequality between boys and girls starts as early as in the mother's womb – but how and why this occurs could be a key to preventing higher rates of preterm birth, stillbirth and neonatal death among boys.
Texas Tech food expert Mindy Brashears discusses current food supply issues, prices.
It took every inch of the Large Hadron Collider's 17-mile length to accelerate particles to energies high enough to discover the Higgs boson. Now, imagine an accelerator that could do the same thing in, say, the length of a football field. Or less. That is the promise of laser-plasma accelerators. Scientists have grappled with building these devices for two decades, and a new theoretical study predicts that this may be easier than previously thought.
A new study of how biodiversity arises shows how a mutation in a single gene in development can lead to different consequences not only in jaw shape, but how this leads to different feeding strategies. It is among the first to show how one genetic change influences trait development and function.
Soils that formed on the Earth’s surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet’s carbon cycle.
University of Adelaide research has for the first time confirmed that women who eat a poor diet before they become pregnant are around 50% more likely to have a preterm birth than those on a healthy diet.
A high-velocity hydrogen cloud hurtling toward the Milky Way appears to be encased in a shell of dark matter, according to a new analysis of data from the National Science Foundation’s Green Bank Telescope (GBT).
Australia can no longer lay claim to the origins of the iconic New Zealand kiwi following University of Adelaide research published in the journal Science today showing the kiwi’s closest relative is not the emu as was previously thought.
A group of 11 genes can successfully predict whether an individual is at increased risk of alcoholism, a research team from the United States and Germany reports
Bacteria that naturally live in the soil have a vast collection of genes to fight off antibiotics, but they are much less likely to share these genes, a new study by researchers at Washington University School of Medicine in St. Louis has revealed
Mayo Clinic researchers have discovered an enzyme they say is tightly linked to how aggressive pancreatic cancer will be in a patient.
Research in an animal model at Saint Louis University supports the potential therapeutic value of an antisense compound to treat Alzheimer's disease.
The ability to discern pitch – to hear the difference between “cat,” “bat” and “hat,” for example – hinges on remarkable gradations in specialized cells within the inner ear. New research from the University of Virginia School of Medicine and the National Institute on Deafness and Communication Disorders has explained, for the first time, what controls these cells’ development and patterning – findings crucial to efforts to reverse hearing loss caused by age, loud sounds or other factors.
A team of researchers has created a new type of lithium ion conductor for future batteries that could be the basis for a whole new generation of solid-state batteries. It uses rock salt Lithium Borohydride (LiBH4), a well-known agent in organic chemistry laboratories that has been considered for batteries before, but up to now has only worked at high temperatures or pressures.
A program aimed at reducing behavior problems in order to boost academic achievement has improved performance in math and reading among low-income kindergartners and first graders, according to a study by researchers at NYU’s Steinhardt School of Culture, Education, and Human Development.
In what is believed to be the largest and most detailed genetic analysis of its kind, researchers at NYU Langone Medical Center and elsewhere have concluded that 69 percent of healthy American adults are infected with one or more of 109 strains of human papillomavirus (HPV).
Vanderbilt astronomers have developed a model that estimates the effect that ingesting large amounts of the rocky material from which ‘terrestrial’ planets like Earth, Mars and Venus are made has on a star’s chemical composition and has used the model to analyze a pair of twin stars which both have their own planets.
On Wednesday May 21, a panel of leading experts in astrophysics and astronomy will describe the scientific and technological roadmap for discovering habitable worlds among the stars. The panel, entitled "The Search for Life in the Universe," is part of the 30th Space Symposium to be held in Colorado Springs, Colorado, May 19 to 22.
Scientists have advanced a brain-scanning technology that tracks what the brain is doing by shining dozens of tiny LED lights on the head. This avoids the radiation exposure and bulky magnets the others require.
It was long assumed that the joining of egg and sperm launched a dramatic change in how and which genes were expressed. Instead, new research shows that totipotency is a step-wise process, manifesting as early as in precursors to sperm, called adult germline stem cells (AGSCs), which reside in the testes. The research was published online in the journal Cell Stem Cell.
