Chlamydia are bacteria that cause venereal diseases. In humans, they can only survive if they enter the cells. This is the only place where they find the necessary metabolites for their reproduction. And this happens in a relatively simple way: The bacteria create a small bubble in the cell and divide in it over several generations.

As the population grows, and the global standard of living improves, humanity's appetite for seafood is increasing. In 2020 seafood consumption reached an all-time high, with an average of 20kg consumed annually by every person on the planet.

Traditional single-cell sequencing methods help to reveal insights about cellular differences and functions—but they do this with static snapshots only rather than time-lapse films. This limitation makes it difficult to draw conclusions about the dynamics of cell development and gene activity. The recently introduced method 'RNA velocity' aims to reconstruct the developmental trajectory of a...

The RCP 8.5 CO2 emissions pathway, long considered a "worst case scenario" by the international science community, is the most appropriate for conducting assessments of climate change impacts by 2050, according to a new article published today in the Proceedings of the National Academy of Sciences. The work was authored by Woods Hole Research Center (WHRC) Risk Program Director Dr. Christopher...

Millimeter by millimeter, your hair is building a record of your diet. As hair strands are built from amino acids that come from your food, they preserve the chemical traces of the protein in that food. It's a strong enough record to show whether you prefer veggie burgers or double bacon cheeseburgers.

When baboons experience trauma in early life, they have higher levels of stress hormones in adulthood—a potential marker of poor health—than their peers who don't experience trauma, even if they have strong social relationships as adults, according to a study led by a University of Michigan researcher.

The research suggests that biodiversity hotspots—such as the Daintree Rainforest in Australia and the Cloud Forests of Ecuador—are teeming with species because they have been ecologically stable for long periods of time, allowing evolution to forge ahead undisturbed.

Virgin Orbit said Monday it has determined what caused the failure of its debut rocket launch and is working toward a second flight that will carry small satellites for NASA.

Whether in flood early-warning systems or in agriculture—rainfall measurements are of great importance. However, there is a lack of accurate data for many regions in the world due to the fact that comprehensive measurements have so far been too expensive. This could change with a new method that has just passed its practical test. Researchers at KIT (Karlsruhe Institute of Technology) and the...

Researchers from Frankfurt and Tübingen say the skull of a very large crane found at the Hammerschmiede fossil site in Allgäu, Bavaria, is more than eleven million years old. It is the earliest evidence of such a large crane in Europe, the paleontologists say. The fossil most closely resembles the skull of today's long-beaked Siberian crane, according to Gerald Mayr of the Senckenberg Research...

A half-century of controversy over two popular bird species may have finally come to an end. In one corner: the Bullock's Oriole, found in the western half of North America. In the other corner: the Baltimore Oriole, breeding in the eastern half. Where their ranges meet in the Great Plains, the two mix freely and produce apparently healthy hybrid offspring. But according to scientists from the...

Despite decades of positive messaging to encourage women and girls to pursue education tracks and careers in STEM, women continue to fall far below their male counterparts in these fields. A new study at Carnegie Mellon University examined 25 languages to explore the gender stereotypes in language that undermine efforts to support equality across STEM career paths. The results are available in the...

When two neutron stars slam together, the result is sometimes a black hole that swallows all but the gravitational evidence of the collision. However, in a series of simulations, an international team of researchers including a Penn State scientist determined that these typically quiet—at least in terms of radiation we can detect on Earth—collisions can sometimes be far noisier.

Despite enormous efforts to advance traditional pharmacology approaches, more than three quarters of all human proteins remain beyond the reach of therapeutic development. Targeted protein degradation (TPD) is a novel approach that could overcome this and other limitations, and thus represents a promising therapeutic strategy. TPD is based on small molecules, generally called 'degraders,' which...

In the human body, proteins sometimes occur in fibrillar aggregates called amyloids. Although certain amyloids are known to have a biological function, amyloid formation is often associated with pathologies, including Alzheimer's and Parkinson's diseases. Understanding how exactly amyloid fibrils form is crucial for gaining insights into the development of such diseases and for advancing with...

With the reopening of flights during the summer holiday season in Europe, many countries have started to see an increase in COVID-19 infections.

A novel mathematical modeling method has been developed to estimate operation models of biomolecular motors from single-molecule imaging data of motion with the Bayesian inference framework. The operation mechanism of a linear molecular motor "chitinase," which moves one-way on a chitin chain with degrading the chain passed by, was elucidated by mathematical modeling of experimental imaging data...

The tension in the outer membrane of cells plays an important role in a number of biological processes. A localized drop in tension, for example, makes it easier for the surface bend inward and form invaginations that will become free vesicles inside the cell. These are delimited by a membrane that contains all proteins originally present in the invaginations. A fundamental function of these...
