Weizmann Institute scientists show that bacteria live inside all cancer cells, from brain to breast to bone, and that each type of cancer has its own type of bacteria. Understanding this relationship could help predict treatment effectiveness or lead to ways of using the bacteria to boost treatments.
The Sun is the brightest object in the sky and has been studied for hundreds of years, but it continues to hide some secrets. We all know that the visible Sun is extremely hot, at temperature of about 5500 degrees.
As a plant grows, it moves cellular material through transporter (motor) proteins along a highway system of microtubule tracks, moving cargo from its version of manufacturing sites to the cell wall construction zone. The Dixit lab found motor proteins necessary for track stability.

Researchers at Tulane University School of Medicine identified a gene that causes an aggressive form of breast cancer to rapidly grow. More importantly, they have also discovered a way to “turn it off” and inhibit cancer from occurring. The animal study results have been so compelling that the team is now working on FDA approval to begin clinical trials and has published details in the journal Scientific Reports.
Not long ago, the center of our galaxy exploded. Our primitive ancestors, already afoot in Africa, probably saw the resulting flare. Now Hubble detects that flash's signature in a huge tail of gas orbiting the galaxy some 200,000 light-years away.
Microcapsules for the storage and delivery of substances are tiny versions of the type of capsule used for fish oil or other liquid supplements. A new method for synthesizing microcapsules, reported in AIP Advances, creates microcapsules with a liquid core that are ideal for the storage and delivery of oil-based materials in skin care products. They also show promise in some applications as tiny bioreactors. In this new method, a surfactant-free microfluidics process is used.
Throughout an individual’s lifetime, the uterus undergoes spontaneous contractions of the uterine wall, which can induce uterine peristalsis, a specific wavelike contraction pattern. These contractions are important for many reproductive processes, but hyperperistalsis could impede fertility and lead to diseases, such as adenomyosis or endometriosis. In an APL Bioengineering article, researchers present two mechanobiology tools for experiments on synthetic or artificial uterine tissue. They wanted to study the negative effects of hyperperistalsis.
Researchers at Mount Sinai have discovered that human acute myeloid leukemia (AML) stem cells are dependent on a transcription factor known as RUNX1, potentially providing a new therapeutic target to achieve lasting remissions or even cures for a disease in which medical advances have been limited.
Using skin cells from human volunteers, researchers at the University of Pittsburgh School of Medicine have created fully functional mini livers, which they then transplanted into rats. In this proof-of-concept experiment, the lab-made organs survived for four days inside their animal hosts.
Generating power through wind or solar energy is dependent on the abundance of the right weather conditions, making finding the optimal strategy for storage crucial to the future of sustainable energy usage. Research published in the Journal of Renewable and Sustainable Energy identifies key indicators that will help achieve balance between green energy storage capacity and harvesting capability and determine the energy potential of a region.
ORNL Story Tips: Shuffling atoms, thinning forests, fusion assembly and nuclear medicine
More than 1,000 bottlenose dolphins live in Florida’s Indian River Lagoon year-round. Although extensively studied, what they do at nighttime is still a mystery. Using satellite telemetry, scientists provide the first documentation that these dolphins have a larger range that encompasses more habitats than previously thought. They regularly leave the brackish waters of the estuarine system and, not only travel into the ocean, but swim substantial distances – up to 20 kilometers – up freshwater rivers, creeks, and canals.
Graphene triangles with an edge length of only a few atoms behave like peculiar quantum magnets. When two of these nano-triangles are joined, a "quantum entanglement" of their magnetic moments takes place: the structure becomes antiferromagnetic. This could be a breakthrough for future magnetic materials, and another step towards spintronics. An international group led by Empa researchers recently published the results in the journal "Angewandte Chemie".
Approximately three quarters of the deaths associated with COVID-19 in the nation’s capital have been among the African American community. A new Georgetown University report illuminates entrenched health and socioeconomic disparities that explain one reason this is occurring. Main points: • 15-year difference in the life expectancy between residents in Ward 3 and Ward 8; • Residents from Wards with more Black residents (5, 7, and 8) more likely hospitalized for preventable health conditions; • Number of Blacks who are obese is 3x higher than Whites; • Number of Blacks with diabetes is 7x higher than Whites; • Number of Blacks who die from heart disease is 2.5 times higher than Whites; • Median household income is 3x less for Blacks; and • Blacks have the lowest percentage of bachelor degree attainment.
A new study finds that regular exercise can offset the blood vessel impairment that occurs after drinking sugary soft drinks. The study is published ahead of print in the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology.
How might the novel coronavirus be prevented from entering a host cell in an effort to thwart infection? A team of biomedical scientists has made a discovery that points to a solution.

Most people in their 50s and older were capable home cooks just before COVID-19 struck America, but only 5% had ordered groceries online, according to a new national poll. The cooking skills that enabled half of older adults to eat dinner at home six or seven days a week may have served them well during the height of the pandemic, the poll suggests. However, they may need added support for grocery shopping as the pandemic continues and older adults seek to avoid COVID-19.
