Weighing Cancer Cells To Personalize Drug Choices

A new study shows a link between patient survival and changes in tumor cell mass after glioblastoma treatment.

3 Questions: Understanding The Haiti Earthquakes

Assistant professors Camilla Cattania and William Frank discuss the science behind the 2010 and 2021 earthquakes in Haiti.

Rover Images Confirm Jezero Crater Is An Ancient Martian Lake

The findings include signs of flash flooding that carried huge boulders downstream into the lakebed.

Cellular Environments Shape Molecular Architecture

Researchers glean a more complete picture of a structure called the nuclear pore complex by studying it directly inside cells.

How The Brain Deals With Uncertainty

Dedicated circuits evaluate uncertainty in the brain, preventing it from using unreliable information to make decisions.

Study Shows Fragile X Treatment Can Incur Resistance, Suggests Ways Around It

While the brain acquires resistance to continuous treatment with mGluR5 inhibitor drugs, lasting effects may still arise if dosing occurs intermittently and during a developmental-critical period.

How The Brain Navigates Cities

We seem to be wired to calculate not the shortest path but the “pointiest” one, facing us toward our destination as much as possible.

Artificial Networks Learn To Smell Like The Brain

When asked to classify odors, artificial neural networks adopt a structure that closely resembles that of the brain’s olfactory circuitry.

New Cancer Treatment May Reawaken The Immune System

By combining chemotherapy, tumor injury, and immunotherapy, researchers show that the immune system can be re-engaged to destroy tumors in mice.

African Network Protects Key Turtle Sites

A network of West African Marine Protected Areas (MPAs) covers key sites used by green turtles, new research shows.

New Research Highlights “Significant Gap” in Evidence About Effectiveness of Relationship Education Programmes

Educators should have not have ‘high’ confidence in the quality of existing relationship education programmes because there is a lack of robust evaluation, experts have warned.

Forest Income and Livelihoods on Pemba: a Quantitative Ethnography

This paper offers a systematic approach to quantifying the socio-economic role of forests for 'forest-dependent' communities.

Expanding the Understanding of Majority‑bias in Children’s Social Learning

Prior experiments with children across seven different societies have indicated U‑shaped age patterns in the likelihood of copying majority demonstrations.

Thousands Of Intestinal Viruses Have Now Been Mapped. And They Can Be Used To Fight Antibiotic Resistance

ANTIBIOTIC RESISTANCE A new method developed at the University of Copenhagen has been used to identify more than 1,000 different types of bactericidal viruses in the human intestines. The researchers behind the new study believe the discovery may help fight antibiotic resistance.

Research Discovery Reveals How A Cancer Cell Resists Radiation Treatment

CANCER Radiation is usually an effective treatment for cancer. Unfortunately, cancer cells are frequently able to defend themselves against the treatment. But now researchers from the University of Copenhagen have shown how cancer cells defend themselves, and their discovery may help ensure that this frontline treatment can save more lives.

Coevolution of Relative Brain Size and Life Expectancy in Parrots

Previous studies have demonstrated a correlation between longevity and brain size in a variety of taxa.

New Sleep Molecule Discovered: “It Shows Just How Complex The Machinery Of Sleep Is”

CELL BIOLOGY Researchers from the University of Copenhagen and Aalborg University presents a new study demonstrating that a small molecule in brain cells affects the level of hypocretin, which is responsible for making us feel awake during the day and tired at night. People with a genetic variation of this molecule have a higher risk of suffering from daytime sleepiness.

Are the More Flexible Great-Tailed Grackles Also Better at Behavioral Inhibition?

Behavioral flexibility should, theoretically, be positively related to behavioral inhibition because one should need to inhibit a previously learned behavior to change their behavior when the task changes (flexibility).

Investigating Sex Differences in Genetic Relatedness in Great-tailed Grackles in Tempe, Arizona to Infer Potential Sex Biases in Dispersal

In most bird species, females disperse prior to their first breeding attempt, while males remain close to the place they hatched.
