Study provides data on gains and losses attributable to individual countries, including the finding that a group from the world’s leading national emitters of GHGs have caused $6 trillion in global economic losses through warming caused by their emissi…

A team successfully transplanted two genetically engineered pig hearts into recently deceased humans in June and July, marking the latest advances toward addressing the nationwide organ shortage and developing a clinical protocol that would provide an …

Over half a century ago, a group of manatees from Bocas del Toro was flown into the artificial Gatun Lake to control the abundance of aquatic plants and for public health reasons. Where are they now?

The results singled out growing-degree days as the most important climatic factor and water holding capacity as the most influential soil property for crop-yield variability.

Researchers have found a new, dynamic protein structure in cells.

In coinfected patients, influenza A virus interferes with SARS-CoV-2 replication in the lung and can continue to do so even more than 1 week after clearance of influenza A, according to new research.

The study is the most rigorous and comprehensive analysis to date of scientific literature on health and spirituality. Overlooking spirituality in health care leaves patients feeling disconnected from the health care system and from the clinicians cari…

The re-entry of abandoned stages of rockets left in orbit from space launches have a six to 10 per cent chance of severely injuring or killing a human being in the next decade, according to a new study. Researchers say governments need to take collecti…

Engineers have succeeded in fabricating a nickel single crystal with only a very few crystalline defects by irradiating nickel powder with a large-radius, flat-top laser beam (i.e., a laser beam whose intensity is uniform across a cross-section of the …

Scientists have developed a new, experimental human cell line from retinal pigment epithelial cells. Called ABC, these cells so closely resemble and retain the properties of native retinal pigment epithelial (RPE) cells, the research team has shown tha…

As most Americans wind down for bed, 15 million people are just clocking into work. These hospital workers, emergency responders, factory operators and others are among the 20 percent of the world’s population who do shift work. Their different sleep-w…

Protein molecules require a defined shape in order to function. When they are created, their building blocks are therefore linked together in a very specific way. Researchers are now taking a closer look at a key step in this process and are investigat…

New research reveals that two different white blood cell types influence cardiac arrhythmia, suggesting that treatments that influence these cells may help reduce patients’ risk of sudden cardiac death.

New research demonstrates that inhibitory and excitatory neuronal circuits of the visual system develop through different processes, even if the organization of the mature circuit is similar. These findings highlight the importance of the continued stu…

Superconductivity is a fascinating state of matter in which an electrical current can flow without any resistance. Usually, it can exist in two forms. One is destroyed easily with a magnetic field and has ‘even parity’, i.e. it has a point symmetric wa…

The emotional context in which eating occurs has been thought to influence eating patterns and diet, with studies finding negative emotions predict excessive calorie intake and poor diet quality. A research article discusses how children’s unhealthy fo…

There is great news to share about hospital patient safety nationally over the last decade with the largest medical record-based study ever finding a significant decrease in hospital adverse events.

Purple sea urchins are munching their way through California’s kelp forests at a speed and scale that have stunned scientists, fishermen and divers alike. But the kelp forests have long been home to red and purple urchins, so it’s clear the three speci…

Using details from historical newspaper accounts and letters, seismologists have learned more about Haiti’s 1860 Jour de Pâques (Easter Sunday) earthquake sequence, and how it might have impacted the country’s most recent devastating earthquakes.

NASA has revealed groundbreaking new views of the cosmos from the James Webb Space Telescope. The images include the deepest infrared view of our universe that has ever been taken.
