Scientists at Tokyo Institute of Technology together with their international collaborators developed a novel quantitative method to quantify the effects of plastic on marine animals. This method successfully shows that plastic ingestion by sea turtles might be causing population declines, despite a lack of strong effects on individual turtles.
A team led by the University of Colorado Boulder is pioneering a new solution to the problem of spring cleaning on the moon: Why not zap away the grime using a beam of electrons?
The research, published recently in the journal Acta Astronautica, marks the latest to explore a persistent, and perhaps surprising, hiccup in humanity's dreams of colonizing the moon: dust. Astronauts walking or driving over the lunar surface kick up huge quantities of this fine material, also called regolith.
Researchers at Linköping University, Sweden, have developed a molecule that absorbs energy from sunlight and stores it in chemical bonds. A possible long-term use of the molecule is to capture solar energy efficiently and store it for later consumption. The current results have been published in the Journal of the American Chemical Society, JACS.
In a major public health success, the introduction of pneumococcal conjugate vaccine PCV13, or Prevnar 13, in 2010 in the United States is associated with reduction in socioeconomic disparities and the near elimination of Black-white-based racial disparities for invasive pneumococcal disease.
More than 13% of women and 3.6% of men on college campuses have an eating disorder of some kind, but fewer than 20% of those affected ever receive treatment due to lack of available clinicians and the stigma associated with seeking help. New research led by eating disorders experts at Washington University School of Medicine in St. Louis indicates a phone app may help change that.
WINSTON-SALEM, N. C. - August 31, 2020 - Specific fungi in the gut associated with a higher risk of Alzheimer's disease and found in people with mild cognitive impairment (MCI) can be altered in a beneficial manner by eating a modified Mediterranean diet, researchers at Wake Forest School of Medicine have found.
The small study is published in the current online edition of the journal EBioMedicine.
It is usually difficult to predict how well drugs will work when they are combined. Sometimes, two antibiotics increase their effect and inhibit the growth of bacteria more efficiently than expected. In other cases, the combined effect is weaker. Since there are many different ways of combining drugs - such as antibiotics - it is important to be able to predict the effect of these drug combinations. A new study has found out that it is often possible to predict the outcomes of combining certain antibiotics by quantitatively characterizing how individual antibiotics work.
A team led by researchers at the University of California, Davis, has discovered a missing link in the evolution of photosynthesis and carbon fixation. Dating back more than 2.4 billion years, a newly discovered form of the plant enzyme rubisco could give new insight into plant evolution and breeding.
Rubisco is the most abundant enzyme on the planet. Present in plants, cyanobacteria (also known as blue-green algae) and other photosynthetic organisms, it's central to the process of carbon fixation and is one of Earth's oldest carbon-fixing enzymes.
NOAA/NASA's Suomi NPP satellite captured two images that tell the story about the smoke coming off the fires in California. One instrument on the provided a visible image of the smoke, while another analyzed the aerosol content within. The images were captured on August 30, 2020.
A team of scientists from the University of Michigan Rogel Cancer Center has developed the first drug-like compounds to inhibit a key family of enzymes whose malfunction is associated with several types of cancer, including an aggressive form of childhood leukemia.
Florida State University researchers have developed a new material that could be used to make flexible X-ray detectors that are less harmful to the environment and cost less than existing technologies.
The team led by Biwu Ma, a professor in the Department of Chemistry and Biochemistry, created X-ray scintillators that use an environmentally friendly material. Their research was published in the journal Nature Communications .
BOSTON- A recent study published in the journal Nature Medicine, led by researchers Todd Allen, PhD, a professor of Medicine at Harvard Medical School (HMS) and group leader at the Ragon Institute of MGH, MIT and Harvard, and Jim Riley, PhD, a professor of Microbiology in the Perelman School of Medicine at the University of Pennsylvania, describes a new Dual CAR T cell immunotherapy that can help fight HIV infection. The paper's first authors are Colby Maldini, a graduate student at the University of Pennsylvania and Daniel Claiborne, PhD, a research fellow at the Ragon Institute.
A consortium of researchers funded by Brazil’s National Council for Scientific and Technological Development (CNPq) and FAPESP has sequenced the genome of Frieseomelitta varia, a native stingless bee (common name: marmelada). The feat extends scientists’ understanding of the evolution of stingless bees (Meliponini) and paves the way for the breeding of commercially useful species.
According to a linguist from RUDN University, the number of COVID-19 cases in a country might be related to the existence of aspirated consonants in its main language of communication. This data can help create more accurate models to describe the spread of COVID-19. The results of the study were published in the Medical Hypotheses journal.
The Covid-19 outbreak has caused immense problems at a macro socioeconomic level throughout the world. Not only has it affected the Covid-19 patients but has also taken a toll on the caregivers, physicians, paramedics and all others who have been engaged in the combat against the pandemic.
