Holograms are everywhere, from driver's licenses to credit cards to product packaging. And now, edible holograms could someday enhance foods. Researchers reporting in ACS Nano have developed a laser-based method to print nanostructured holograms on dried corn syrup films. The edible holograms could also be used to ensure food safety, label a product or indicate sugar content, the researchers say.
ROCHESTER, Minn. -- A new study by Mayo Clinic researchers has identified that a chromosome instability gene, USP24, is frequently missing in pediatric patients with neuroblastoma, an aggressive form of childhood cancer. The finding provides important insight into the development of this disease. The study is published in Cancer Research, the journal of the American Association for Cancer Research.
A mutation in the spike protein of SARS-CoV-2--one of several genetic mutations in the concerning variants that have emerged in the United Kingdom, South Africa, and Brazil--makes the virus up to eight times more infectious in human cells than the initial virus that originated in China, according to research published in the journal eLife.
Teens who bully, harass, or otherwise victimize their peers are not always lashing out in reaction to psychological problems or unhealthy home environments, but are often using aggression strategically to climb their school's social hierarchy, a University of California, Davis, study suggests. These findings point to the reasons why most anti-bullying programs don't work and suggest possible strategies for the future.

Leesburg, VA, February 17, 2021--According to an open-access article in ARRS' American Journal of Roentgenology (AJR), COVID-19-related disseminated leukoencephalopathy (CRDL) represents an important--albeit uncommon--differential consideration in patients with neurologic manifestations of coronavirus disease (COVID-19).
Your morning cereal or oatmeal. The bread on your sandwich. The corn chips for your snack, and the cookies for dessert. Not one would be possible with the humblest of ingredients: the seed.
Seeds such as wheat, rice and corn directly provide about 70% of the calories eaten by people every day. And they ultimately provide nearly every morsel of food, either by providing feed for livestock or by being grown into fruits and vegetables. It's no overstatement to say that without seeds, civilization would be impossible.
Some of the planet's rarest metals - used in the manufacture of smartphones and other electrical equipment - are increasingly being found in everyday consumer plastics, according to new research.
Scientists from the University of Plymouth and University of Illinois at Urbana-Champaign tested a range of new and used products including children's toys, office equipment and cosmetic containers.
Lesbian, gay and bisexual (LGB*) people are significantly more likely to have mental health conditions and report alcohol and drug misuse than heterosexual people - according to a new study led by UCL researchers in collaboration with the University of East Anglia and City, University of London.
The findings, published today in Psychological Medicine, come despite apparently more tolerant societal attitudes towards same-sex relationships.
Memorial Sloan Kettering Cancer Center (MSK) physicians and scientists presented new research at the 2021 American Society of Clinical Oncology Genitourinary Cancers Symposium held virtually February 11-13. Notably, MSK medical oncologist Robert Motzer, MD, presented encouraging data from a phase III randomized study that assessed two new treatment combinations as first-line treatments that may prolong survival in people with advanced kidney cancer. Dr. Motzer's findings were also published on February 13 in the New England Journal of Medicine.
Most people infected with SARS-CoV-2 are able to recover from the disease at home - even if they might experience very stressful disease progressions. Some have no symptoms at all. But about ten percent of those affected become so severely ill that they have to be treated in a hospital. The assumption that a weak immune system is behind a severe progression is short-sighted. Especially with critical progressions, the immune system works under intense pressure, but does not manage to control the virus.
Computing - Modeling COVID dynamics
To better understand the spread of SARS-CoV-2, the virus that causes COVID-19, Oak Ridge National Laboratory researchers have harnessed the power of supercomputers to accurately model the spike protein that binds the novel coronavirus to a human cell receptor.
These simulations also shed light on the ligand molecules that can inhibit such binding, pointing the way to potential drug therapies.
Researchers have discovered that the use of Cytoglobin (CYGB) as an intravenous drug could delay liver fibrosis progression in mice.
Between January 2012 and March 2018, there were an average of 1,000 failures each year at large North American gas power plants due to unscheduled fuel shortages and fuel conservation interruptions. This is a problem as the power grid depends on reliable natural gas delivery from these power plants in order to function. More than a third of all U.S. electricity is generated from natural gas.
DALLAS - Feb. 16, 2021 - A study that identifies how a coronavirus protein called Nsp1 blocks the activity of genes that promote viral replication provides hope for new COVID-19 treatments.
Since the start of the pandemic, scientists have worked endlessly to understand SARS-CoV-2, the coronavirus that causes COVID-19. Even with the arrival of vaccines, the virus is still spreading and there is a need to develop alternative therapies. Scientists hope to achieve this by studying how SARS-CoV-2 infects cells and propagates itself while avoiding the body's natural immune system.
