For The Better

How is climate change affecting the permanently frozen soils of the Arctic? What will the consequences be for the global climate, human beings, and ecosystems? And what can be done to stop it?

A new oral treatment for ulcerative colitis that focuses on reducing inflammation in gut microbiota has been developed by researchers.

Although mindfulness originates within an individual, a new study has found the benefits do not end with this person. The real payoffs emerge when an individual’s mindfulness is translated into mindful interactions and relationships. Such interactions …

Research on wastewater finds that a large spike in acetaminophen preceded a spike in viral RNA during one COVID-19 wave in Western New York.

Researchers are learning more about how special regulatory T cells can impact the immune system’s response and how those cells could be manipulated for potential treatments for food allergies and autoimmune disease.

When heat waves hit, they don’t just take a toll on people — plants suffer too. That’s because when temperatures rise, certain plant defenses don’t work as well, leaving them more susceptible to attacks from pathogens and pests. Scientists say they ha…

An international group of geneticists and archaeologists have found that the ancestry of dogs can be traced to at least two populations of ancient wolves. The work moves us a step closer to uncovering the mystery of where dogs underwent domestication, …

A dramatic outbreak of kelp-eating sea urchins along the Central Coast of California in 2014, leading to a significant reduction in the region’s kelp forests, was driven primarily by the emergence of sea urchins from their hiding places rather than an …

Mitochondria are the power plants of cells, and they contain their own genetic material and RNA molecules. Scientists have now discovered that certain modifications in mitochondrial RNA boost the invasive spread of cancer cells by supporting protein sy…

Scientists have shown it is possible to reverse a key process that allows pancreatic cancer cells to grow and spread around the body. These findings show that a protein called GREM1 is key to regulating the type of cells found in pancreatic cancer — a…

Fruit flies are known for their sweet tooth, but new research also indicates they may offer hints to how animals sense — and avoid — high concentrations of salt. Using mutant fruit flies, zoologists have identified a new high-salt receptor on the ton…

Engineers have created a new type of semiconductor laser that accomplishes an elusive goal in the field of optics: the ability to maintain a single mode of emitted light while maintaining the ability to scale up in size and power. It is an achievement …

Astrophysicists have developed the first 3D simulation of the entire evolution of a jet — from its birth by a rotating black hole to its emission far from the collapsing star. Simulation shows that as the star collapses, its material falls on the disk…

Researchers have simulated SARS-CoV-2 infection in human lungs, thereby generating key insights into the mechanisms involved. Using cultured lung tissue samples, the researchers showed that the virus responsible for COVID-19 has only limited capacity f…

Researchers explore a basic building block used in the fabrication of many DNA nanoforms. Known as a Holliday junction, this nexus of two segments of double stranded DNA has been used to form elaborate, self-assembling crystal lattices at the nanometer…

The skin’s top layer contains a diverse set of hundreds of lipid molecules called ceramides with varying chain lengths that play a vital role in its barrier function.

Researchers have found that organic vapor can dissolve molecular salts in a phenomenon known as organic deliquescence. Similar to how water vapor can induce deliquescence of compounds like calcium chloride, this phenomenon will be useful for developing…
