Researchers have found that T cells from people who have recovered from COVID-19 or received the Moderna or Pfizer-BioNTech vaccines are still able to recognize several concerning SARS-CoV-2 variants.

A new study calculates the probability of living past age 110, which, though rare, likely will increase this century.

Imaging spectroscopy can help predict water stress in wild blueberry barrens, according to a new study. Researchers deployed a drone with a spectrometer to photograph wild blueberry fields, then process the images to measure reflected light spectra from plants for properties that would help them estimate water potential. Incorporating data from the images into models allowed them predict water...

In COVID-19 patients whose symptoms were mild, researchers found that they were more likely than sicker patients to have signs of prior infection by similar, less virulent coronaviruses.

Hereditary information is passed from parent to offspring in the genetic code, DNA, and epigenetically through chemically induced modifications around the DNA. New research has uncovered a mechanism which adjusts these modifications, altering the way information beyond the genetic code is passed down the generations.

A new technique called sci-Space, combined with data from other technologies, could lead to four-dimensional atlases of gene expression across diverse cells during embryonic development of mammals. Such atlases would map how the gene transcripts in individual cells reflect the passage of time, cell lineages, cell migration, and location on the developing embryo. They would also help illuminate the...

Scientists have been looking for half an electron as a basis for a quantum computer. They investigated a promising experimental setup just to find that the signals they measured were not telling the truth.

Current rates of plastic emissions globally may trigger effects that we will not be able to reverse, argues a new study. According to the authors, plastic pollution is a global threat, and actions to drastically reduce emissions of plastic to the environment are 'the rational policy response.'

Our brains have sensory cells, which process the faces that we see, and memory cells dedicated to storing data from person encounters. But until now, a hybrid neuron capable of linking vision to memory -- and explaining how we recall familiar faces -- remained elusive.

Fifteen years ago, an electrical and materials professor pioneered a method for integrating a laser onto a silicon wafer. The technology has since been widely deployed in combination with other silicon photonics devices to replace the copper-wire interconnects that formerly linked servers at data centers, dramatically increasing energy efficiency -- an important endeavor at a time when data...

Zeolites are extremely porous materials: Ten grams can have an internal surface area the size of a soccer field. Their cavities make them useful in catalyzing chemical reactions and thus saving energy. An international research team has now made new findings regarding the role of water molecules in these processes. One important application is the conversion of biomass into biofuel.

Metal additive manufacturing (AM) experiments are slow and expensive. Engineers are using physics-informed neural networks to predict the outcomes of complex processes involved in AM. The team trained the model on supercomputers using experimental and simulated data. They recreated the dynamics of two benchmark experiments in metal AM. The method could lead to fast prediction tools for AM in the...

Researchers have now uncovered their crucial role in closing the period of brain plasticity that follows birth, finding them to be key to the development of sensory and cognitive faculties. Over the longer term, these findings will make it possible to envisage new strategies for reintroducing brain plasticity in adults, thereby promoting rehabilitation following brain lesions or neurodevelopmental...

Antibiotic sales soared during India's first surge of COVID-19, suggesting that the drugs were inappropriately used to treat mild and moderate COVID-19 infections, according to new research. The excessive usage is especially concerning because antibiotic overuse increases the risk for drug-resistant infections -- not just in India, but worldwide.

A researcher is reporting that use of a plastic drape during catheter insertion in very low birth-weight newborn babies can lower the rates of hypothermia, and she is recommending replacing cloth blanket and towels with them.

A team of scientists has devised a more accurate way to predict the effects of climate change on plants and animals -- and whether some will survive at all.

Researchers have discovered that genetic variants in a neuro-associated gene called SPTBN1 are responsible for causing a neurodevelopmental disorder. The study is a first step in finding a potential therapeutic strategy for this disorder, and it increases the number of genes known to be associated with conditions that affect how the brain functions.

Scientists have set out to harness the potential of self-assembling peptides (SAPs) in intracellular spaces. They present a de novo designed peptide, Y15, which displays a strong tendency to assemble in cellular environments. The addition of Y15-tagged bioactive proteins can functionalize these assemblies, enhancing their utility and relevance by leaps and bounds.

Plastic waste is considered one of the biggest environmental problems of our time. Researchers surveyed consumers in Germany about their use of plastic packaging. Their research reveals that fundamental changes in infrastructures and lifestyles, as well as cultural and economic transformation processes, are needed to make zero-waste shopping the norm.

An affordable lab system uses grass blades to turn cells into cultured meat, by creating a scaffold that animal stem cells can attach to and grow on.

Scientists resurrected the genus Philozoon by using modern technologies to thoroughly characterize two of the species of algae that biologist Patrick Geddes had investigated in the mid-to-late 19th century, along with six new related ones.

What if a microscope allowed us to explore the 3D microcosm of blood vessels, nerves, and cancer cells instantaneously in virtual reality? What if it could provide views from multiple directions in real time without physically moving the specimen and worked up to 100 times faster than current technology?

New research has shown that many of the symptoms in fibromyalgia syndrome (FMS) are caused by antibodies that increase the activity of pain-sensing nerves throughout the body. The results show that fibromyalgia is a disease of the immune system, rather than the currently held view that it originates in the brain.

The establishment of nasal mucosal immunity against SARS-CoV-2 through a nasal vaccine could be the most efficient way to combat COVID-19 infection.
