Older adults who are childless in the U.S. are more likely to be college educated, working and white than those with children, and their numbers are growing.

Scientists have simulated the transition of the SARS-CoV-2 spike protein structure from when it recognizes the host cell to when it gains entry, according to a study published today in eLife.

A new family of materials that could result in improved digital information storage and uses less energy may be possible thanks to a team of Penn State researchers who demonstrated ferroelectricity in magnesium-substituted zinc oxide.

Rare earth elements are finding their way into Colorado water supplies, driven by changes in climate, finds a new study published in the journal Environmental Science & Technology.

Brown dwarfs aren't quite stars and aren't quite planets, and a new study suggests there might be more of them lurking in our galaxy than scientists previously thought.

By taking advantage of a natural lens in space, astronomers have captured an unprecedented look at X-rays from a black hole system in the early universe.

A spectacular portrait of the galaxy Centaurus A has been captured by astronomers using the Dark Energy Camera mounted on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile. This galaxy's peculiar appearance—cloaked in dark tendrils of dust—stems from a past interaction with another galaxy, and its size and proximity to Earth make it one of the...

A coalition of animal rights groups filed a lawsuit Tuesday to stop Wisconsin's wolf hunt this fall and invalidate a state law mandating annual hunts, arguing the statutes don't give wildlife officials any leeway to consider population estimates.

If you're heading back to the office after working from home, you may re-encounter interruptions you've not experienced for 18 months: The family pet is replaced by chatty coworkers who stop at your desk to say hi.

With today's existing translation tools to overcome language barriers, global collaboration should be no major feat for researchers. Yet throughout the COVID-19 pandemic, articles published in Chinese journals focusing on critical aspects of the disease were often never cited by English journals. As a result, U.S. academics wasted precious time performing research thereby replicating already...

A Paris auction house will seek to sell in October the world's biggest known example of the dinosaur triceratops, known as "Big John", with the spectacular skeleton on show to the public beforehand, organisers said Tuesday.

A new study explains the science behind microscale concave interfaces (MCI)—structures that reflect light to produce beautiful and potentially useful optical phenomena.

Climate change and meteorological disasters have become grave challenges to human beings. Because of global warming and the increasing extreme weather and climate events it has caused, meteorological disasters have led to worsening socioeconomic damage throughout the world in recent decades. The United Nations reported that, between 1998 and 2017, disaster-hit countries experienced direct economic...

Researchers with the Single-Cell Center, Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS), have developed a fast, low-cost and high-throughput technique capable of profiling dynamic metabolic features from just one isogenic sample of cells.

Internal job applicants who face rejection are nearly twice as likely to leave their organizations than those who were either hired for an internal job or had not applied for a new job at all.

Each day we confront risks at home, at work and in society, but the COVID-19 pandemic, including the rise of new variants, has changed our relationship with risk. As workers and employers determine health measures and back-to-the-office plans, calculations and perceptions of risk loom large.

Ocean currents embody motion, snaking their way from the tropics to the poles and back, shifting vast quantities of water from moment to moment. But they are also incredibly old, following their basic course for millions of years.

The ongoing debate over raising the national minimum wage generally focuses on the negative impact it would have on employers, but a new study finds it has a positive effect on a different group: consumers.

Canada needs a more cohesive strategy to help the more than 1.7 million people currently living in unaffordable, overcrowded or poor-condition housing, says UBC expert Dr. Penny Gurstein, head of the Housing Research Collaborative at UBC's school of community and regional planning.

Scientists are less likely to adopt important new ideas in biomedicine introduced by women researchers, a new study has found.

Scanning tunneling microscopes capture images of materials with atomic precision and can be used to manipulate individual molecules or atoms. Researchers have been using the instruments for many years to explore the world of nanoscopic phenomena. A new approach by physicists at Forschungszentrum Jülich is now creating new possibilities for using the devices to study quantum effects. Thanks to...

Scientists have uncovered a fascinating new insight into what caused one of the most rapid and dramatic instances of climate change in the history of the Earth.

The asteroid Vesta is the second largest asteroid in our Solar System. With a diameter of about 330 miles, it orbits the sun between the planets Mars and Jupiter.

Researchers seeking ways to discover more about bee behavior without disrupting the nest have built the world's first 'wild bee nests' with built-in webcams.
