To kickstart the 30th anniversary year of the NASA/ESA Hubble Space Telescope, Hubble has imaged a majestic spiral galaxy. Galaxy UGC 2885 may be the largest known in the local universe. It is 2.5 times wider than our Milky Way and contains 10 times as many stars.
A collaboration of researchers at Louisiana State University, University of Missouri, and University of Tennessee found that peer victimization is associated with adverse psychological and behavioral problems, including depression and risky health behaviors such as substance use and unprotected sex with multiple partners. In 2015, approximately one-third of high school students in the US reported having sex recently. Of these, 43% had not used a condom, 21% had drunk alcohol or used drugs before sexual intercourse, and 14% had not used any contraception.
Most living things have an internal body clock which regulates when they sleep and when they wake up. A complex set of genes turning on and off, make this body clock run over roughly 24 hours, and a gene known by the acronym BMAL1 is one of the master regulators of this clock, controlling many other body clock genes and pathways.
The internal body clock being out of alignment with the environment is why we get jet lag, but more recently, scientists have also found that the body clock affects immunity too.
Mindfulness has been shown to reduce negative emotions in both healthy individuals as well as patients with psychological problems. Studies have also shown that mindfulness is effective for treating clinical emotional problems like anxiety, depression, stress and trauma related disorders.
Complex Innovative Design (CID) trials could be transformed for the better, following the publication of recommendations, published today in the British Journal of Cancer* (Monday).
The authors believe, if implemented, the ten recommendations they've developed for CID trials could ultimately reduce the time it takes to get innovative treatments to patients with cancer.
They are now calling on clinicians, funders, regulators and the pharmaceutical industry to get behind the recommendations and work together to rapidly implement them.
WASHINGTON, January 5, 2020 -- Due to long-term and systemic issues leading to the consistent exclusion of African Americans in physics and astronomy, a task force is recommending sweeping changes and calling for awareness into the number and experiences of African American students studying the fields.
A new frailty index shows promise in determining how acute illness affects functional ability in older patients admitted to hospital, according to a new study in CMAJ (Canadian Medical Association Journal) co-led by researchers from Dalhousie University, Canada, and University College London (UCL), United Kingdom: http://www.cmaj.ca/lookup/doi/10.1503/cmaj.190952
With the recent legalization of cannabis edibles in Canada, physicians and the public must be aware of the novel risks of cannabis edibles, argue authors in a commentary in CMAJ (Canadian Medical Association Journal): http://www.cmaj.ca/lookup/doi/10.1503/cmaj.191217
Astronomers seeking to learn about the mechanisms that formed massive black holes in the early history of the Universe have gained important new clues with the discovery of 13 such black holes in dwarf galaxies less than a billion light-years from Earth.
These dwarf galaxies, more than 100 times less massive than our own Milky Way, are among the smallest galaxies known to host massive black holes. The scientists expect that the black holes in these smaller galaxies average about 400,000 times the mass of our Sun.
Allergic reactions in the skin can be caused by many different chemical compounds found in creams, cosmetics, and other topical consumer products, but how they trigger the reaction has remained somewhat mysterious.
A new study suggests the way some chemicals displace natural fat-like molecules (called lipids) in skin cells may explain how many common ingredients trigger allergic contact dermatitis, and encouragingly, suggests a new way to treat the condition.
EUGENE, Ore. - Researchers are moving closer to a new approach for improving spinal fusion procedures and repairing broken or defective bones that avoids an over-production of bone that commonly occurs in current treatments.
In a preclinical study, researchers significantly reduced undesired bone growth outside of targeted repair areas in rat femurs by delivering a potent bone-forming protein called bone morphogenetic protein, or BMP, using a new biomaterial made from heparin.
Monash University researchers have developed the world's most efficient lithium-sulphur battery, capable of powering a smartphone for five continuous days.
Prototype cells have been developed in Germany. Further testing in cars and solar grids to take place in Australia in 2020.
Researchers have a filed patent on the manufacturing process, and will capture a large share of Australia's lithium chain.
A new study by San Francisco State University Assistant Professor of Management Nara Jeong suggests that CEOs look to the White House for leadership on social responsibility -- but not the way you might expect. It turns out that corporate leaders are less likely to act on their values when they're in agreement with the president. And their social responsibility efforts increase when they don't agree with the leadership of the commander in chief.
New Haven, Conn. -- A new study led by Yale University researchers finds that scaling up use of methadone and buprenorphine -- medications for treating opioid use disorder known as opioid agonist therapies (OATs) -- could greatly reduce HIV transmission rates and prevent deaths in Ukraine, where the disease is epidemic among people who inject drugs.
The study was published in The Lancet.
Crop rotation is vital to any crop production system. Rotating crops maintains crop productivity and soil health by replenishing organic matter, nutrients, soil structure, and other properties while also improving water management and reducing erosion. Rotating crops also reduces the buildup of soilborne pathogens and diseases.
