(Press-News.org) Humans were making tools from whale bones as far back as 20,000 years ago, according to a study conducted by scientists from the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB), the French National Centre for Scientific Research (CNRS), and the University of British Columbia. This discovery broadens our understanding of early human use of whale remains and offers valuable insight into the marine ecology of the time.
Whales, the largest animals on Earth, were an important source of food and materials such as oil and bone. For this reason, they are believed to have played a key role in the survival of many coastal human groups. However, tracing the origins of human-whale interactions is challenging, as coastal archaeological sites are especially fragile and vulnerable to rising sea levels, making it difficult to preserve evidence of early human-marine mammal relationships.
The research, led by Jean-Marc Pétillon (CNRS) along with ICTA-UAB scientist Krista McGrath and published in Nature Communications, analyzes 83 bone tools excavated from sites around the Bay of Biscay in Spain, along with 90 additional bones from Santa Catalina Cave, also located in the province of Biscay. The authors used mass spectrometry and radiocarbon dating to identify the species and age of the samples.
“Our study reveals that the bones came from at least five species of large whales, the oldest of which date to approximately 19,000–20,000 years ago. These represent some of the earliest known evidence of humans using whale remains as tools”, says Jean-Marc Pétillon, senior author of the research.
According to Krista McGrath, leading author of the paper, “ZooMS is a powerful technique for investigating past sea mammal diversity, particularly when diagnostic morphometric elements are missing from bone remains and objects, which is often the case for bone artefacts. We managed to identify species such as sperm whales, fin whales, blue whales, all still present in the Bay of Biscay today, as well as grey whales, a species now mostly restricted to the North Pacific and Arctic Oceans”.
In addition, chemical data extracted from the bones suggest that the feeding habits of these ancient whales differed slightly from those of their modern counterparts, pointing to potential changes in behavior or the marine environment. Overall, this discovery not only enhances our understanding of early human use of whale remains but also sheds light on the role whales played in past ecosystems.

Germinated flours in breadmaking: Striking a balance between nutrition and quality
2025-05-27
A recent study explores the potential of germinated flours as functional ingredients in breadmaking, highlighting both their nutritional benefits and their technological challenges.
The growing demand for healthier foods has inspired the scientific community to reexamine traditional ingredients through a modern lens. One such example is germinated flours, which are emerging as a promising alternative for enhancing the nutritional profile of bread, one of the most widely consumed foods worldwide.
At the Food Science and Technology Laboratory at ESPOL, researchers comprehensively reviewed the latest findings on the use of germinated ...
Timely initiation of statin therapy for diabetes shown to dramatically reduce risk of heart attack and stroke
2025-05-27
Taking a statin medication is an effective, safe, and low-cost way to lower cholesterol and reduce risk of cardiovascular events. Despite clinicians recommending that many patients with diabetes take statins, nearly one-fifth of them opt to delay treatment. In a new study, researchers from Mass General Brigham found that patients who started statin therapy right away reduced the rate of heart attack and stroke by one third compared to those who chose to delay taking the medication. The results, which can help guide decision-making conversations between clinicians and their patients, are published in the Journal of the ...

Record-breaking performance in data security achieved with quantum mechanics
2025-05-27
A joint team of researchers led by scientists at King Abdullah University of Science and Technology (KAUST) and King Abdulaziz City for Science and Technology (KACST) has reported the fastest quantum random number generator (QRNG) to date based on international benchmarks. The QRNG, which passed the required randomness tests of the National Institute of Standards and Technology, could produce random numbers at a rate nearly a thousand times faster than other QRNG.
“This is a significant leap for any industry that depends on strong data security,” said KAUST Professor Boon Ooi, who led the study, which is published in Optics Express. KAUST ...

Study: Emotional responses crucial to attitudes about self-driving cars
2025-05-27
PULLMAN, Wash. -- When it comes to public attitudes toward using self-driving cars, understanding how the vehicles work is important—but so are less obvious characteristics like feelings of excitement or pleasure and a belief in technology’s social benefits.
Those are key insights of a new study from researchers at Washington State University, who are examining attitudes toward self-driving cars as the technology creeps toward the commercial market—and as questions persist about whether people will readily adopt them.
The study, published in the journal Transportation Research, ...

Can AI analogize?
2025-05-27
Can large language models (LLMs) reason by analogy? Some outputs suggest that they can, but it has been argued that these results reflect mimicry of the results of analogical reasoning in the models’ training data. To test this claim, LLM’s have been asked to solve counterfactual problems that are unlikely to be similar to problems in training data sets. Here is an example:
Let’s solve a puzzle problem involving the following fictional alphabet:
[x y l k w b f z t n j r q a h v g m u o p d i c s e]

AI aversion in social interactions
2025-05-27
An experimental study suggests that people are less likely to behave in a trusting and cooperative manner when interacting with AI than when interacting with other humans. Scientists use experimental games to probe how humans make social decisions requiring both rational and moral thinking. Fabian Dvorak and colleagues compared how humans act in classic two-player games when playing with another human to how humans act when playing with a large-language model acting on behalf of another human. Participants played the Ultimatum ...
In dry conditions, locust babies are born with their first lunch
2025-05-27
Locusts have undersized babies—with their first lunch already in their guts—in dry conditions. Desert locusts have two distinct modes—solitary and gregarious—that are behaviorally and visibly different. The insects also live in the Sahara desert, an environment with frequent dry conditions. Koutaro Ould Maeno and colleagues explored how a lack of moisture and the presence of other locusts shift reproductive resource allocation in the insects. In lab experiments, the authors raised locusts in crowds and in isolation. Crowd-reared females produced fewer, larger eggs than females raised in ...
