New platform creates digital map for marine biobanks‎

A new digital platform developed under the leadership of CIIMAR is making Portugal's marine biodiversity more accessible by bringing together thousands of biological resources into a single access point. The Blue Biobanks Digital Research Platform aims to bridge scientific research and industry by simplifying the identification of organisms and biological materials with potential applications in areas such as biotechnology, bioremediation, aquaculture, health, cosmetics and many others.

Collective agreements are least common where workers need them most‎

Workers earning the lowest wages are the least likely to be covered by collective agreements in Germany, despite being the group for whom these protections are arguably most important. In 2021, only 34% of workers in the lowest wage decile were covered by collective agreements, compared with more than 60% of workers in the middle of the wage distribution, according to findings of a new report by the ROCKWOOL Foundation Berlin (RFBerlin) and the Institute for Employment Research (IAB) in Nuremberg.

Understanding anti-blackness at Hispanic-serving research universities‎

At Hispanic-Serving Institutions (HSIs), conversations about diversity often center on supporting Hispanic/Latine students. New research from scholars at University of New Mexico highlights an important and sometimes overlooked issue--the experiences of Black students at these universities, specifically those classified as R1, or highly research-intensive institutions.

Geoscientists reveal how Earth's forces are shaping the 'Roof of the World'‎

Geoscientists at the University of Glasgow have helped reveal new evidence about the formation of one of the highest mountainous areas on Earth—the Tibetan Plateau. A study by an international team of Chinese and U.K. geoscientists shows that the unique topography at the summit of the plateau is shaped by processes going on deep in Earth.

To ancient astronomers, Theta Eridani was brighter for 1,000 years—now we know why‎

There's a bit of a historical mystery surrounding the star Theta Eridani. Ptolemy in the second century A.D. and al-Sufi in A.D. 964 both recorded Theta Eridani as one of the 13 brightest stars in the sky. Hipparchus may have said the same. But there's a problem. For it to be one of the 13 brightest, it had to be much more luminous than it is today.

New sensors capture warning signs before fish deaths in Lake Victoria‎

Researchers from King's College London recorded the warning signs of a major low-oxygen event in Lake Victoria just hours before fish deaths were reported by local communities, demonstrating why earlier warning systems are urgently needed.

Dark energy flips its sign, but the Hubble tension refuses to budge‎

For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the Supernova Cosmology Project, led by Saul Perlmutter, and the High-Z Supernova Search Team, led by Brian Schmidt and Adam Riess, discovered something strange: The expansion is speeding up. The finding earned them the 2011 Nobel Prize in Physics. The leading explanation for this acceleration is "dark energy," a mysterious force usually modeled as a constant called Lambda, pushing space apart. Combined with cold dark matter, this gives us the LCDM model, the standard picture of the cosmos for the past 25 years.

Children back group claims over evidence, but privacy reduces bias, experiments reveal‎

As we move closer to Election Day 2026, voting preferences are moving back into focus—and with them, analyses of what drives partisanship at the polls. However, less frequently asked is when Americans show evidence of partisan behavior: shortly or well after reaching the legal voting age? As teenagers? In elementary school?

Why natural forests survive heat waves better than planted forests‎

When a record-breaking drought and heat wave swept across China's Yangtze River Basin in 2022, forests across the region faced an extreme test. The event provided a rare opportunity for researchers to test how different forests respond when rising temperatures and water shortages strike at the same time.

Moderate warming rewires one-third of microalga's genes, study finds‎

Researchers have demonstrated for the first time that the microalga Chlamydomonas reinhardtii alters the activity of about one-third of its protein-coding genes in response even to moderate temperature changes. The study, published in the journal The Plant Cell, points to far-reaching consequences of climate change for aquatic ecosystems and soil. The research team is from the Cluster of Excellence Balance of the Microverse at Friedrich Schiller University Jena and the Leibniz Institute for Natural Product Research and Infection Biology—Hans Knöll Institute (Leibniz-HKI).
