From life-like faces to elaborate nature scenes, tattoos are a true art form. But the inks are unregulated in the U.S. Their chemical composition is a mystery, which means potential side effects are largely unknown. Now, scientists are shedding light o…

Researchers have developed a new gene therapy approach that shows promise for treating the dry form of Age Related Macular Degeneration (AMD) — a progressive eye disease that affects up to 10% of adults over 65 years of age and is a leading cause of s…

An international team of astronomers has discovered an exoplanet that could be completely covered in water.

Our own immune system can become the enemy when mechanisms that are actually protective get out of control. In ANCA-associated vasculitis, excessive inflammatory reactions lead to pulmonary hemorrhages that can be fatal if left untreated. Researchers h…

Researchers have found that gut bacteria in mice co-evolve with their hosts.

A new analysis of a beaver anklebone fossil found in Montana suggests the evolution of semi-aquatic beavers may have occurred at least 7 million years earlier than previously thought, and happened in North America rather than Eurasia.

If autonomous vehicles are ever going to achieve widespread adoption, we need to know they are capable of navigating complex traffic situations, such as merging into heavy traffic when lanes disappear on a highway. To that end, researchers have develop…

Researchers are developing a coronavirus vaccine designed to be less sensitive to mutations and equipped for future strains. The vaccine showed promising results in mice in a newly published study, and the researchers now hope to be able to take it to …

Researchers have conducted a landmark survey to identify and stratify antimicrobial stewardship programs into four different groups — a first step toward studying the effectiveness of these models to best enhance patient care and reduce the rise of an…

Kelp forms vast seaweed forests along temperate coastlines, which sequester large amounts of atmospheric carbon. But according to a new study, warming oceans could reduce the capacity of kelp forests to trap carbon for long periods in deep ocean stores…

Many tumor cells mist themselves with a protective perfume that disables the immune system. But a drug already approved for other purposes can apparently render this weapon harmless. The researchers now want to further optimize the compound. In the med…

A first-of-its-kind study of the 50 largest cities in the U.S. found a lack of preparedness, specifically to evacuate carless and vulnerable populations. Only seven cities had strong plans, including Charlotte, North Carolina; Cleveland; Jacksonville; …

The growing demand for nickel, copper, cobalt, and zinc — raw materials for solar panels and batteries — puts the mining and metals sector in the spotlight of climate change mitigation. But how does the sector itself fare when it comes to meeting the…

Do you have a secret stash of chocolates that you keep from your partner, or do you intentionally keep your spouse from knowing about something you bought online? New research indicates that small but commonly hidden actions such as these may be good f…

Gene therapy has partly restored the function of the retina’s cone receptors in two children who were born completely colourblind, reports a new study.

Researchers have made an important discovery about the way our brains process the sensations of sound and touch. The new study reveals how the brain’s different sensory systems are all closely interconnected — with regions that respond to touch also i…

People with an obsessive urge to constantly check the news are more likely to suffer from stress, anxiety, as well as ill health, finds a new study.

Caregivers who consume digital media for relaxation are more likely to engage in negative parenting practices, according to a new multinational study.

New research has found evidence that Earth’s early continents resulted from being hit by comets as our Solar System passed into and out of the spiral arms of the Milky Way Galaxy, turning traditional thinking about our planet’s formation on its head.

Marked differences in how climate change will affect different parts of Europe require further focus and political attention if European agriculture is to adapt to future climatic conditions, say researchers.
