Image: Hubble sees a stellar furnace

An orange glow radiates from the center of NGC 1792, the heart of this stellar furnace. Captured by the NASA/ESA Hubble Space Telescope, this intimate view of NGC 1792 gives us some insight into this galactic powerhouse. The vast swathes of tell-tale blue seen throughout the galaxy indicate areas that are full of young, hot stars, and it is in the shades of orange, seen nearer the center, that the older, cooler stars reside.

Newly developed material could lead to lighter, safer car designs

A new form of 3-D-printed material made by combining commonly-used plastics with carbon nanotubes is tougher and lighter than similar forms of aluminium, scientists say.

Researchers advance simple and inexpensive diagnostic blood test

In diagnostic medicine, biopsies, where a sample of tissue is extracted for analysis, is a common tool for the detection of many conditions. But this approach has several drawbacks—it can be painful, doesn't always extract the diseased tissue, and can only be used in a sufficiently advanced disease stage, making it, in some cases, too late for intervention. These concerns have encouraged researchers to find less invasive and more accurate options for diagnoses.

CLOUD at CERN reveals the role of iodine acids in atmospheric aerosol formation

In a paper published today in the journal Science, the CLOUD collaboration at CERN shows that aerosol particles made of iodic acid can form extremely rapidly in the marine boundary layer—the portion of the atmosphere that is in direct contact with the ocean. Aerosol particles in the atmosphere affect the climate, both directly and indirectly, but how new aerosol particles form and influence clouds and climate remains relatively poorly understood. This is particularly true of particles that form over the vast ocean.

Dinosaur frills were likely the result of sexual selection

Why dinosaurs evolved such a huge diversity of crests and frills on their skulls has long been an enigma.

Researchers find peptide that treats, prevents killer citrus disease

New research affirms a unique peptide found in an Australian plant can destroy the No. 1 killer of citrus trees worldwide and help prevent infection.

Winner-takes-all synthetic gene circuit process opens new pathways to disease treatment

A new process for inserting synthetic gene circuits into host cells, developed by a team of bioengineers at Arizona State University, has broad implications for improving the effectiveness of a range of disease therapies.

Hearing acrobatics: Dynamic, delicate connection between protein filaments enables hearing

The sense of hearing is, quite literally, a molecular tightrope act. Turns out, it involves acrobatics as well.

Reducing biases about autism may increase social inclusion

Efforts to improve the social success of autistic adolescents and adults have often focused on teaching them ways to think and behave more like their non-autistic peers and to hide the characteristics that define them as autistic. Psychology researchers at The University of Texas at Dallas, however, have been focusing on another approach: promoting understanding and acceptance of autism among non-autistic people.

Happy childhood? That's no guarantee for good mental health

It's well understood that a difficult childhood can increase the likelihood of mental illness, but according to new research from the University of South Australia, a happy and secure childhood does not always protect a child from developing a mental illness later in life.

Survey: Most Americans say they'll continue health precautions after COVID-19

A new national survey of more than 2,000 Americans by The Ohio State University Wexner Medical Center finds most plan to continue many of the pandemic precautions in the name of public health, even when the pandemic is over.

Online searches can help foreshadow future COVID-19 surges and declines, new study shows

Online searches for mobile and isolated activities can help to predict later surges and declines in COVID-19 cases, a team of researchers has found. Its findings, based on a four-month analysis of online searches, offer a potential means to anticipate the pathways of the pandemic—before new infections are reported.

Higher blood pressure over life span increases congestive heart failure risk in Black people

Starting with early childhood, otherwise healthy Black people show signs of slightly diminished heart muscle strength and a slightly higher blood pressure than their white counterparts, factors which may put them on a course for early development of congestive heart failure, researchers report.

Front-of-package product names and ingredient lists of infant and toddler food can be hard to navigate
