CHAMPAIGN, Ill. -- Researchers are using artificial intelligence to help airlines price ancillary services such as checked bags and seat reservations in a way that is beneficial to customers' budget and privacy, as well as to the airline industry's bottom line.
How can a planet be "hotter than hot?" The answer is when heavy metals are detected escaping from the planet's atmosphere, instead of condensing into clouds.
Observations by NASA's Hubble Space Telescope reveal magnesium and iron gas streaming from the strange world outside our solar system known as WASP-121b. The observations represent the first time that so-called "heavy metals"--elements heavier than hydrogen and helium--have been spotted escaping from a hot Jupiter, a large, gaseous exoplanet very close to its star.
WASHINGTON - Current design standards for United States hydrologic infrastructure are unprepared for the increasing frequency and severity of extreme rainstorms, meaning structures like retention ponds and dams will face more frequent and severe flooding, according to a new study.
Police officers who had a greater proportion of colleagues previously named in use-of-force complaints were more likely to
be named in subsequent complaints
Authors recommend police departments consider how assigning officers with histories of using excessive force affects the
behavior of other officers
EVANSTON, Ill. --- A new Northwestern University study investigated how Chicago police officers' exposure to peers who had been accused of misconduct shaped their involvement in subsequent excessive force cases.
LAWRENCE -- A paper appearing today in a special edition of the Journal of Abnormal Psychology questions much of the statistical evidence underpinning therapies designated as "Empirically Supported Treatments," or ESTs, by Division 12 of the American Psychological Association.
A growing number of scientists are looking for fast, cost-effective ways to convert carbon dioxide gas into valuable chemicals and fuels.
Now, an international team of researchers has revealed a new approach that utilizes a series of catalytic reactions to electrochemically reduce carbon dioxide to methane, the main ingredient in natural gas, eliminating an intermediate step usually needed in the reduction process.
Understanding the internal energy flow - including the metabolism - of large ocean creatures like sharks and rays could be key to their survival in a changing climate, according to a new study.
University of Queensland PhD candidate Christopher Lawson led a team of researchers investigating the bioenergetics of sharks and rays; data which may reveal how they will fare in a drastically changing ocean.
"Shark and rays play crucial roles as top predators in many marine ecosystems, but are currently among the most threatened vertebrates," Mr Lawson said.
The way barn owl brains use sound to locate prey may be a template for electronic directional navigation devices, according to a team of Penn State engineers who are recreating owl brain circuitry in electronics.
"We were already studying this type of circuitry when we stumbled across the Jeffress model of sound localization," said Saptarshi Das, assistant professor of engineering science and mechanics.
Whether it is oil gushing through pipelines or blood circulating through arteries, how liquids flow through tubes is perhaps the most fundamental problem in hydrodynamics. The challenge is to maximize transport efficiency by minimizing the loss of energy to friction between the moving liquid and the stationary tube surfaces. Counterintuitively, adding a small amount of large, slow moving polymers to the liquid, thus forming a 'complex liquid', leads to faster, more efficient transport.
Researchers at the University of Birmingham have shown that it's possible to produce a compound with anti-cancer properties directly from feverfew - a common flowering garden plant.
The team was able to extract the compound from the flowers and modify it so it could be used to kill chronic lymphocytic leukaemia (CLL) cells in the laboratory.
Feverfew is grown in many UK gardens, and also commonly sold in health food shops as a remedy for migraine and other aches and pains.
(Boston)--In an effort to protect the planet and preserve its natural treasures for future generations, another contraception revolution that provides options for populations not currently being served by modern contraception may be the answer according to a Perspective in this week's New England Journal of Medicine.
(WASHINGTON, July 31, 2019) -- Women who receive a blood transfusion after giving birth are twice as likely to have an adverse reaction related to the procedure, such as fever, respiratory distress, or hemolysis (destruction of red blood cells), compared with non-pregnant women receiving the same care, according to a new study published today in Blood Advances. Women with preeclampsia, a condition marked by high blood pressure during pregnancy, were found to be at the greatest risk for problems.
SEATTLE -- July 31, 2019 -- In a paper published in the July 31 issue of Science Translational Medicine, researchers at Fred Hutchinson Cancer Research Center used CRISPR-Cas9 to edit long-lived blood stem cells to reverse the clinical symptoms observed with several blood disorders, including sickle cell disease and beta-thalassemia.
It's the first time that scientists have specifically edited the genetic makeup of a specialized subset of adult blood stem cells that are the source of all cells in the blood and immune system.
In spring 2018, the surprising discovery of superconductivity in a new material set the scientific community abuzz. Built by layering one carbon sheet atop another and twisting the top one at a "magic" angle, the material enabled electrons to flow without resistance, a trait that could dramatically boost energy efficient power transmission and usher in a host of new technologies.
A new study harnessed the unique genetic history of the people of Finland to identify variations in DNA that might predispose certain individuals to disease, whether or not they are Finnish themselves. The study was conducted by researchers at Washington University School of Medicine in St. Louis, in collaboration with the University of California, Los Angeles; the University of Michigan and other institutions, including several partners in Finland.
