BIRMINGHAM, Ala. - Cervical cancer kills more than 300,000 middle-aged women a year, and 19 of the 20 nations with the highest death rates are sub-Saharan countries.
Now an international team, including Akinyemi I. Ojesina, M.D., Ph.D., University of Alabama at Birmingham, has published the first comprehensive genomic study of cervical cancers in sub-Saharan Africa, with a focus on tumors from 212 Ugandan patients with cervical cancer.
Ojesina is one of five researchers who jointly supervised this work, which was published in Nature Genetics.
On Aug. 9, 2020 NASA's Aqua satellite imaged the Apple Fire near Big Bear Lake in California using its false-color bands in order to be able to distinguish burn scars from the surrounding area more easily. The combination of reflectance bands 7, 2, and 1 on the MODIS instrument are most useful for distinguishing burn scars from naturally low vegetation or bare soil and enhancing floods. The MODIS Corrected Reflectance imagery is available only as near real-time imagery. The imagery can be visualized in Worldview and the Global Imagery Browse Service (GIBS).
Philadelphia, August 11, 2020 - Autism spectrum disorder (ASD) is rarely diagnosed until symptoms arise, often well into childhood. Evidence however, is mounting that developmental abnormalities likely emerge in the brain long before then: early identification of babies at risk for ASD could allow for interventions that would improve their developmental outcomes.
A new study in Nucleic Acids Research, published by Oxford University Press, suggests a possible effective treatment strategy for patients suffering from prion disease.
New research out today highlights the future effects of climate change on important fish stocks for south-west UK fisheries.
The study, which generated future projections of climate impacts on fish in a rapidly warming sea region, suggests changes in the availability and catchability of commercially important Atlantic fish species including Atlantic cod, Dover sole, monkfish and lemon sole. This could have implications for fisheries management, and future fish diets of the British public.
Denver--(Embargoed for 7 a.m. EST August 8, 2020) The combination of first-line nivolumab and ipilimumab demonstrated an improvement of overall survival for patients with unresectable malignant pleural mesothelioma compared to platinum-based chemotherapy, according to research presented today at the International Association for the Study of Lung Cancer Virtual Presidential Symposium.
A new publication on the impacts of deep-seabed mining by 13 prominent deep-sea biologists, led by University of Hawai'i at Mānoa oceanography professor Craig Smith, seeks to dispel scientific misconceptions that have led to miscalculations of the likely effects of commercial operations to extract minerals from the seabed.
People hoping to get a handle on future droughts in the American West are in for a disappointment, as new USC-led research spanning centuries shows El Niño cycles are an unreliable predictor.
KANSAS CITY, MO--Since its discovery, scientists have been using the much-lauded gene editing tool CRISPR to alter the DNA of model organisms and uncover the functions of thousands of genes. Now, researchers at the Stowers Institute for Medical Research in Kansas City, Missouri, and the Andalusian Center of Developmental Biology at Pablo de Olavide University in Seville, Spain, have harnessed the technology to target gene messages (messenger RNA) involved in early vertebrate development.
Each cigarette smoked a day by heavier smokers increases the risk of contracting some diseases by more than 30 per cent, according to a new international study published today.
The Australian Centre for Precision Health based at the University of South Australia led the study, which links heavier smoking* with 28 separate health conditions, revealing a 17-fold increase in emphysema, 8-fold increase in atherosclerosis (clogged arteries) and a 6.5-fold higher incidence of lung cancer.
DALLAS - Aug. 7, 2020 - UT Southwestern scientists have developed a genetically engineered mouse and imaging system that lets them visualize fluctuations in the circadian clocks of cell types in mice. The method, described online in the journal Neuron, gives new insight into which brain cells are important in maintaining the body's master circadian clock. But they say the approach will also be broadly useful for answering questions about the daily rhythms of cells throughout the body.
Spontaneous mutations of a single gene are likely to cause serious developmental disorders of the excretory organs and genitalia. This is shown in an international study led by the University of Bonn and published in the journal Frontiers in Cell and Developmental Biology. The researchers also owe their findings to an unusual model organism: the zebrafish.
A group of researchers from three Japanese universities has discovered why the western subarctic Pacific Ocean, which accounts for only 6 percent of the world's oceans, produces an estimated 26 percent of the world's marine resources.
Japan neighbors this ocean area, known for rich marine resources including salmon and trout. The area, located at the termination of the global ocean circulation called the ocean conveyor belt, has one of the largest biological carbon dioxide draw-downs of the world's oceans.
A key component of the Gulf Stream has markedly slowed over the past century--that's the conclusion of a new research paper in Nature Communications published on August 7. The study develops a method of tracking the strength of near-shore ocean currents using measurements made at the coast, offering the potential to reduce one of the biggest uncertainties related to observations of climate change over the past century.
As the most abundant constituent in Earth's atmosphere, dinitrogen (N2) is the main nitrogen source of N-containing compounds in the Earth. Therefore, N2 fixation and activation are essential both for nature and humans. Nevertheless, the high bond dissociation energy (942 kJ/mol) and large HOMO-LUMO gap (10.82 eV) make N2 exhibit extremely low reactivity and be regarded as an inert gas.
