An analysis of data from university COVID-19 screening programs reveals omicron arrived earlier and took over more quickly than experts predicted. Data from university screening programs helped researchers alert hospitals about an imminent surge of omicron cases. The findings suggest university screening programs could be a valuable tool for surveillance of future infectious diseases.

A research team has shown that a synthetic IL-9 receptor allows cancer-fighting T cells to do their work without the need for chemotherapy or radiation.

Interdisciplinary study shows changes to brain structures associated with memory and cognitive function are directly linked to social isolation. The data shows that socially isolated people are 26% more likely to develop later dementia. The study has implications for health and social care policy, in the wake of the COVID-19 pandemic.

Higher levels of optimism were associated with longer lifespan and living beyond age 90 in women across racial and ethnic groups.

Up to now, protecting hardware against manipulation has been a laborious business: expensive, and only possible on a small scale. And yet, two simple antennas might do the trick.

A new technique can dramatically accelerate programs known as shell scripts, through a process called parallelization, while ensuring the programs return accurate results.

The fossil of a still-unnamed species provides the first known record of the abelisaurid group of theropods from a middle Cretaceous-aged (approximately 98 million years old) rock unit known as the Bahariya Formation, which is exposed in the Bahariya Oasis of the Western Desert of Egypt.

With the second version of the International Bathymetric Chart of the Southern Ocean (IBCSO v2), an international group of researchers recently presented the best and most detailed seafloor map of the Southern Ocean, which plays a pivotal role in the Earth system.

A team of engineers has demonstrated for the first time that the Bluetooth signals emitted constantly by our mobile phones have a unique fingerprint that can be used to track individuals' movements.

In a new study, researchers have discovered that paternal nicotine taking is associated with addiction-like behaviors, cognitive deficits, and anxiety-like behaviors in male offspring.

A new study reveals that walking for exercise can reduce new frequent knee pain among people age 50 and older diagnosed with knee osteoarthritis, the most common form of arthritis. Additionally, findings from the study indicate that walking for exercise may be an effective treatment to slow the damage that occurs within the joint.

Using cutting-edge electron microscopes and novel techniques, a team of researchers has found a way to map phonons -- vibrations in crystal lattices -- in atomic resolution, enabling deeper understanding of the way heat travels through quantum dots, engineered nanostructures in electronic components.

A recently discovered, rare and persistent rapid-fire fast radio burst source -- sending out an occasional and informative cosmic ping from more than 3.5 billion light years away -- helps to reveal the secrets of the broiling hot space between the galaxies.

Using radio transmitters, scientists have gained new insights into the behavior of medium ground finches in the Galapagos Islands. A study reveals daily movement patterns covering an area equivalent to the size of 30 soccer fields.

Reducing the excess prevalence of low birthweight, preterm birth or small-for-gestational-age birth in low- and middle-income countries may lead to substantial long-term human capital gains when it comes to both long-term schooling and lifetime income gains, according to a new study.

As cities test different approaches to handling 911 calls, a new study shows dispatching mental health specialists for nonviolent emergencies can be beneficial. In Denver, it reduced reports of less serious crimes and lowered response costs.

A new study offers direct evidence showing where near-light speed particle acceleration occurs inside the largest explosion known in the solar system, the solar flare.

New research offers evidence that getting a second or third dose of the COVID-19 vaccine in the final stages of pregnancy offers protection for infants against SARS-CoV-2 infection (the virus that causes COVID-19 illness).

Engineers have developed a therapeutic that they say avoids major allergic reactions that plagued previous versions while maintaining its therapeutic activity. The keys to the discovery were the use of a similar, membrane-bound version of stem cell factor delivered in engineered lipid nanocarriers.

Research has revealed that an abrupt change in climate conditions in the North Atlantic around 800 years ago played a role in a decline in Atlantic salmon populations returning to rivers. Subsequent human exploitation of salmon combined to reduce their populations still further.

As the cherished rainforest in South America's Amazon River region continues to shrink, the river itself now presents evidence of other dangers: the overexploitation of freshwater fish.

A new study describes one of the first entirely new drug delivery microencapsulation approaches in decades.

Pregnant women's use of alcohol correlates with that of their partner, a new study shows. Paying attention to both parents' use of alcohol may help to prevent drinking during pregnancy, as well as fetal exposure to the adverse effects of alcohol.

New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a better understanding of natural hazards like earthquakes and volcanoes.
