New research suggests that regular exercise may improve the well-being of African American cancer survivors, but most survivors do not meet current recommendations for physical activity. The findings are published early online in CANCER, a peer-reviewed journal of the American Cancer Society (ACS).
In a study published in Advanced Materials, researchers at Aalto University, the University of Tokyo, Sichuan University, and the University of British Columbia have demonstrated that plant-derived cellulose nanocrystals (CNCs) can form an adhesive that fully integrates the concepts of sustainability, performance, and cost which are generally extremely challenging to achieve simultaneously.
New research from the University of Sheffield has discovered that switching to a rich diet after eating a restricted diet can decrease life expectancy and have negative effects on health.
It has long been known that restricting food intake can extend lifespan however researchers have now provided new insight into why, as well as how diets could benefit humans in terms of slowing ageing and the onset of age-related disease.
Maize is a staple food all over the world. In the United States, where it's better known as corn, nearly 90 million acres were planted in 2018, earning $47.2 billion in crop cash receipts.
But, under the effects of climate change, this signature crop may not fare so well. As the world tries to feed a population skyrocketing to nine billion by 2050, that has major implications. So, what can we do about it? The answer might be exotic.
One of the strategies used for biological control of the South American fruit fly Anastrepha fraterculus is sterilization of males by X-ray or gamma-ray irradiation. The aim of the procedure is to bring about a decrease in the wild population of these insects.
A. fraterculus is a major crop pest in the South Region of Brazil, mainly affecting apple and peach orchards.
LOS ANGELES, Feb. 21, 2020 -- A common medication that reduces bleeding could be a treatment for bleeding stroke, particularly if administered quickly, according to late breaking science presented today at the American Stroke Association's International Stroke Conference 2020. The conference, Feb. 19-21 is in Los Angeles, a world premier meeting for researchers and clinicians dedicated to the science of stroke and brain health.
The Chan group at the Beckman Institute for Advanced Science and Technology has recently developed a probe named CoxFluor, which is able to distinguish between Cyclooxygenase-2, an enzyme that plays a major role in driving the progression of cancer, and Cyclooxygenase-1, which is expressed in all cells.
There are two tropical cyclones affecting American Samoa in the South Pacific Ocean on Feb. 21. Tropical Storm Vicky has triggered warnings, while Tropical Cyclone 18P continues to develop. The Global Precipitation Measurement mission or GPM satellite provided a look at the rainfall rates occurring in both storms.
Vicky is located to the southeast of American Samoa and 18P is located to the northwest. American Samoa is a U.S. territory covering seven islands and atolls. The capital city of Pago Pago is located on Tutuila, the largest island.
Advanced leaf-out, or early sprouting and opening leaves, is a direct response to climate change. In northern hemisphere, leaf-out has advanced at a rate of 4-5 days per decade on average since 1980s, according to synthesis of over 40 satellite-derived phenology studies across decades and regions. Scientists are curious to know if, in turn, this advancement would affect climate by modulating seasonal cycles of surface energy, water, and carbon budgets.
Immunotherapy is showing great promise for treating cancer. But so far, this approach has been effective in only about 20% of all cancers. To advance those results, researchers are looking for new ways to mobilize the immune system to destroy tumors.
Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team led by Professor Sungjae Cho in the KAIST Department of Physics developed a thickness-controlled black phosphorous tunnel field-effect transistor (TFET) that shows 10-times lower switching power consumption as well as 10,000-times lower standby power consumption than conventional complementary metal-oxide-semiconductor (CMOS) transistors.
Three scientists from the University of Chicago have run the numbers, and they believe there may be a way to make a material that could conduct both electricity and energy with 100% efficiency--never losing any to heat or friction.
The breakthrough, published Feb. 18 in Physical Review B, suggests a framework for an entirely new type of matter, which could have very useful technological applications in the real world. Though the prediction is based on theory, efforts are underway to test it experimentally.
Researchers at the Smithsonian Tropical Research Institute (STRI) discovered a massive, 7,000-year-old fossilized coral reef near the institute's Bocas del Toro Research Station in Panama. Spanning about 50 hectares, it rewards paleontologists with an unusual glimpse of a "pristine" reef that formed before humans arrived.
"All modern reefs in the Caribbean have been impacted in some way by humans," said STRI staff scientist Aaron O'Dea. "We wanted to quantify that impact by comparing reefs that formed before and after human settlement."
The early-stage research in rats, by a group of scientists led by Imperial College London, revealed two existing medications can boost the body's own repair machinery, by triggering the release of stem cells from the bone marrow.
The scientists published their research in the journal npj Regenerative Medicine.
The team say the two drugs (currently used for bone marrow transplants and bladder control) could be used for different types of bone fractures, including to the spine, hip and leg, to aid healing after surgery or fractures.
HOUSTON - Comprehensive profiling of tumor samples taken from patients with osteosarcoma shows that multiple factors contribute to the traditionally poor responses observed from treatment with immune checkpoint inhibitors, according to new research from The University of Texas MD Anderson Cancer Center.
