Researchers report the development of ultrahigh refractive index metamaterials which are integrated with a low refractive index polymer producing distributed Bragg reflector (DBR). The highest refractive index in the visible and near-infrared regions w…

Scientists have proposed a new mechanistic model (AD2) for Alzheimer’s, looking at it not as a brain disease, but as a chronic autoimmune condition that attacks the brain.

Researchers used cryo-electron microscopy to reveal the structure of bacteria’s ‘propellers’ in near atomic detail.

Even small objects, such as dust and leaves, can block sunlight from reaching solar cells, and understanding how the loss of incoming radiation affects power output is essential for optimizing photovoltaic technology. Researchers explore how different …

Researchers have analyzed the manifestations of COVID-19 in the lungs and colon and pinpointed the differences at a molecular level. Their findings form the basis for the identification of novel biomarkers and the development of new treatment strategies.

Researchers in quantum technology have succeeded in developing a technique to control quantum states of light in a three-dimensional cavity. In addition to creating previously known states, the researchers are the first ever to demonstrate the long-sou…

The use of virtual fencing to manage cattle grazing on sagebrush rangelands has the potential to create fuel breaks needed to help fight wildfires, a recent study found.

Twelve years after an oil spill coated nearly 35 miles of the Kalamazoo River, new research confirms that turtles rehabilitated in the aftermath of the disaster had high long-term survival rates.

After 10 months flying in space, NASA’s Double Asteroid Redirection Test (DART) — the world’s first planetary defense technology demonstration — successfully impacted its asteroid target on Monday, the agency’s first attempt to move an asteroid in sp…

Scientists have pinpointed a protein in lysosomes that is involved in recycling a crucial fatty component of cell membranes to keep cells healthy.

Drinking two to three cups of coffee a day is linked with a longer lifespan and lower risk of cardiovascular disease compared with avoiding coffee, according to new research. The findings applied to ground, instant and decaffeinated varieties.

The first large, real-world study of the effectiveness of mRNA COVID-19 vaccines during pregnancy found these vaccines, especially two initial doses followed by a booster, are effective in protecting against serious disease in expectant mothers whether…

A new scoring tool that helps to ‘transparently’ prioritize which countries are in greatest need of COVID-19 vaccines, has been developed by researchers.

Researchers developed a more accurate simulation of the impact that formed Earth’s largest crater — Vredefort crater — nearly two billion years ago. They found the impactor (most likely an asteroid) that formed Vredefort crater is much larger than pr…

Astronomers have assembled the largest-ever compilation of high-precision galaxy distances, called Cosmicflows-4.

Stronger hurricanes that are reenergised by jet stream winds are twice as likely to cross the Atlantic and wreak havoc in Europe than weaker ones, new research has found.

Genetic testing for amyotrophic sclerosis (ALS), also called motor neuron disease, is usually restricted to patients with family members also affected by ALS, or patients who do not have a family history but have symptoms starting early, under the age …

Astronomers believe bright reflections beneath the surface of Mars’ South Pole are not necessarily evidence of liquid water, but instead geological layers.

Researchers are developing new ways to study why an antibiotic causes hair cell death and permanent hearing loss in people.

Rendering the invisible visible is among scientists’ favorite challenges. In their efforts to uncover how the olfactory system makes sense of thousands of otherwise invisible odors, scientists now have uncovered more of the cellular and molecular steps…
