Researchers have created a newborn hearing screening system that uses cheap earbuds and a smartphone instead of an expensive commercial device.

Twilight observations have enabled astronomers to spot three near-Earth asteroids (NEA) hiding in the glare of the Sun. These NEAs are part of an elusive population that lurks inside the orbits of Earth and Venus. One of the asteroids is the largest ob…

A new protocol extends live imaging time for C. elegans larvae and adults using light sheet fluorescence microscopy from 20 minutes to more than 2 hours, while avoiding heat stress in the specimen.

Hair loss is undesirable for many men — and women — because one’s hairstyle is often closely tied to their self-confidence. And while some people embrace it, others wish they could regrow their lost strands. Now, researchers have used artificial inte…

Despite the broad recognition of mimicry among bumble bees, distinct North American mimicry rings have yet to be defined, due in part to the prevalence of intermediate and imperfect mimics in this region. Scientists employ a generalization approach usi…

Climate change will increase opportunities to see rainbows, according to a new study. The study’s authors estimate that by 2100, the average land location on Earth will experience about 5% more days with rainbows than at the beginning of the 21st centu…

An international study shows that the number of atmospheric aerosol particles measured at observation sites across Europe has, on average, declined since the beginning of the 2000s. The declining trend was also observed by the climate models studied, b…

Researchers have determined the three-dimensional structure of the proteolytic enzyme PAPP-A. The results may allow us to better understand the basic biology that regulates linear growth of vertebrates. The same regulatory mechanisms are also involved …

While both protect from severe disease, inactivated SARS-CoV-2 and spike mRNA vaccines trigger different T-cell responses.

A new technique to improve the coating of nanoparticles used in cancer therapy may enhance tumor targeting.

A new way of reprogramming our immune cells to shrink or kill off cancer cells has been shown to work in the otherwise hard to treat and devastating skin cancer, melanoma. The discovery demonstrates a new way to clear early stage pre-cancerous and even…

The risk of developing breast cancer is higher in what are known as dense breasts, which appear white in mammograms, than in nondense breasts, which appear grey. Researchers have now shown that there are major biological differences dense breasts and n…

The researchers suggest that mass school shootings are different from other forms of mass murder, and that they should be looked at as a distinct phenomenon. Factors other than severe mental illness contribute to the vast majority of cases.

Researchers have drawn inspiration from the art of origami to create programmable surfaces that allow engineers to alter physical properties of a uniform substance across a range of directions.

Findings suggest COVID-19 presents caregivers with unique challenges not evident in other patients. Data also confirm previous research that, in general, the bulk of family caregiving falls to women, with 75 percent of the COVID-19 caregivers in the st…

A beautiful tapestry of colors, showing the ghostly remains of a gigantic star, was captured in incredible detail with the VLT Survey Telescope, hosted at the European Southern Observatory’s Paranal site in Chile.

A new study looks at several aspects of the effects of exposure to earlier forms of the SARS-CoV-2 spike antigen on the immune system’s reaction to the prevailing Omicron variants.

A study has found that Eurasian jays can pass a version of the ‘marshmallow test’ — and those with the greatest self-control also score the highest on intelligence tests.

Global warming is changing the Arctic by causing permafrost thaw, glacier melt, droughts, fires and changes in vegetation. These developments are strongly linked to the energy exchange between land and the atmosphere. Researchers have now shown that di…

A study indicated that sleep quality impacted women’s mood and changed how they felt about advancing in their careers. Meanwhile, men’s aspirations were not impacted by sleep quality. The researchers discovered this finding in a two-week-long survey st…
