University of California regents on Thursday approved a multiyear plan to raise tuition and fees at the system's 10 campuses.

Having friends may not only be good for the health of your social life, but also for your actual health—if you're a hyena, that is. Strong social connections and greater maternal care early in life can influence molecular markers related to gene expression in DNA and future stress response, suggests a new University of Colorado Boulder study of spotted hyenas in the wild.

By analyzing peoples' visitation patterns to essential establishments like pharmacies, religious centers and grocery stores during Hurricane Harvey, researchers at Texas A&M University have developed a framework to assess the recovery of communities after natural disasters in near real time. They said the information gleaned from their analysis would help federal agencies allocate resources...

Millennials, often referred to as the "job-hopping generation," represent a group of young workers who once grabbed the national spotlight with their publicized demands for "fun" work perks, such as happy hours. However, researchers at the Novak Leadership Institute at the University of Missouri and Kansas State University discovered today's young workers—ages 21-34—represent a life-stage...

Scientists at Duke University have developed a suite of four new tests that can be used to detect coal ash contamination in soil with unprecedented sensitivity.

The University of Surrey has built an artificial intelligence (AI) model that identifies chemical compounds that promote healthy aging—paving the way towards pharmaceutical innovations that extend a person's lifespan.

As a fourth-generation cattle farmer, Jared Decker knows that cattle suffer from health and productivity issues when they are taken from one environment—which the herd has spent generations adapting to—to a place with a different climate, a different elevation or even different grass. But as a researcher at the University of Missouri, Decker also sees an opportunity to use science to solve...

To meet an ambitious goal of carbon neutrality by 2045, California's policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers at the University of California, Irvine warn that future climate change may limit the ecosystem's ability to perform this service.

Using information obtained from around a dozen earthquakes detected on Mars by the Very Broad Band SEIS seismometer, developed in France, the international team of NASA's InSight mission has unveiled the internal structure of Mars. The three papers published on July 23, 2021 in the journal Science, involving numerous co-authors from French institutions and laboratories, including the CNRS, the...

Lower winds and better weather helped crews using bulldozers and helicopters battling the nation's largest wildfire in southern Oregon while a Northern California wildfire crossed into Nevada, prompting new evacuations as blazes burn across the West.

For much of human history, animals and plants were perceived to follow a different set of rules than the rest of the universe. In the 18th and 19th centuries, this culminated in a belief that living organisms were infused by a non-physical energy or "life force" that allowed them to perform remarkable transformations that couldn't be explained by conventional chemistry or physics alone.

A new method that analyzes how individual immune cells react to the bacteria that cause tuberculosis could pave the way for new vaccine strategies against this deadly disease, and provide insights into fighting other infectious diseases around the world.

A new study, led by University of Minnesota Twin Cities engineering researchers, shows that the stiffness of protein fibers in tissues, like collagen, are a key component in controlling the movement of cells. The groundbreaking discovery provides the first proof of a theory from the early 1980s and could have a major impact on fields that study cell movement from regenerative medicine to cancer...

Based on the analysis of marsquakes recorded by NASA's InSight mission, the structure of Mars's crust has now been determined in absolute numbers for the first time. Beneath the InSight landing site, the crust is either approximately 20 or 39 kilometers thick. That is the result of an international research team led by geophysicist Dr. Brigitte Knapmeyer-Endrun at the University of Cologne's...

Researchers at the University of Regensburg track the first step in the reaction of one single dye pigment with oxygen at an unprecedented resolution.

For the first time, a team of international scientists have proven that cockatoos, an iconic Australian bird species, learn from each other a unique skill—lifting garbage bin lids to gather food. The world-first research published today in Science, confirms that cockatoos spread this novel behavior through social learning. Led by Barbara Klump and Lucy Aplin (Max Planck Institute of Animal...

As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight?

Researchers from Osaka University have found that the attachment of a ubiquitin molecule to a protein called PCNA at the lysine 107 position causes gross chromosomal rearrangements. This lysine is located where two PCNA molecules interact, and the ubiquitin attachment to it may change the ring structure they form. The ubiquitin attachment occurs through the action of Rad8 (a ubiquitin ligase) and...

Nuclear fusion offers the potential for a safe, clean and abundant energy source.

Plastics offer many benefits to society and are widely used in our daily life: they are lightweight, cheap and adaptable. However, the production, processing and disposal of plastics are simply not sustainable, and pose a major global threat to the environment and human health. Eco-friendly processing of reusable and recyclable plastics derived from plant-based raw materials would be an ideal...

Silicon, a semi-metal, bonds in its natural form with four other elements and its three-dimensional structure takes the form of a tetrahedron. For a long time, it seemed impossible to achieve the synthesis and characterisation of a two-dimensional equivalent—geometrically speaking, a square. Now scientists from the field of Inorganic Chemistry at Heidelberg University have succeeded in producing...

Around 470 million years ago, plants began to conquer the terrestrial surfaces. The first examples had a small axis terminated by a structure capable of forming spores, almost like current mosses. The appearance of plant organs mediated the explosive radiation of land plants, which shaped the surface of our planet and allowed the establishment of terrestrial animal life.

When Alexander Flemming discovered a mold on a culture plate overgrown with bacteria in 1928, he did not expect to find one of the most widely used active substances: penicillin. Accidental discoveries and the identification of active ingredients from traditional remedies, such as the morphine of the opium poppy, have shaped the discovery of new medicines for a long time.

In the depths of space, there are celestial bodies where extreme conditions prevail: Rapidly rotating neutron stars generate super-strong magnetic fields. And black holes, with their enormous gravitational pull, can cause huge, energetic jets of matter to shoot out into space. An international physics team with the participation of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has now proposed a...
