A Mount Holyoke College geologist looking for ornamental garden stones, chanced upon a dark-colored fossil bone, which he later identified as the distal (outer) end of the right humerus (long upper-arm) of a large neotheropod. The bone dates to the Lower Jurassic period, between 201 million and 174.1 million years ago.
Although essential genes are only a tiny part of the genes of most organisms (about 5% to 10%), they are important because they are responsible for much of the organism's protein synthesis and because they are the targets of most antibiotics. Essential genes are notoriously hard to study, however, because their removal leads to the death of the organism.
Tuberculosis is currently the deadliest infectious disease in the world, affecting nearly 2 billion people. It is caused by the organism Mycobacterium tuberculosis.
Twenty aviation students recently received job offers through a partnership between Auburn University and Delta Air Lines.
Researchers at the University of Missouri and the University of Minnesota have discovered how HIV evades one of the body’s best defenses – and their collaborative work could offer hope for future treatments that stop the spread of HIV in the body.Messenger RNA (mRNA) from HIV is known to utilize a host cell’s system in order to create its own viral proteins.
The direct conversion of methane gas to liquid methanol at the site where it is extracted from the Earth holds enormous potential for addressing a number of significant environmental problems. Developing a catalyst for that conversion has been a critical focus for Associate Professor Heather Kulik and the lab she directs at MIT.
An unprecedented new telescope image of the Milky Way galaxy’s turbulent center has revealed nearly 1,000 mysterious strands, inexplicably dangling in space.
A recent paper by two Cambridge University scientists shows how a concept important in physics as a whole, called “gauge,” plays out in the specific theory of electromagnetism.
Decades of research has shown that limits on calorie intake by flies, worms, and mice can enhance life span in laboratory conditions.
Systems engineering is the technique used for planning and managing the huge array of materials, manpower, methods and flows required in modern manufacturing and construction projects.
Researchers at the University of Gothenburg in Sweden have achieved a deeper understanding of the chemical structure of intestinal mucus, a key part of the body’s innate immune system.
How do speeding cells come to a screeching halt at just the right point within blood vessels?
Fog and low stratus clouds over airports can create dangerous travel conditions that result in costly delays and disrupted travel plans.
A growing problem for the vast amount of digital information the world generates is how to store it efficiently and keep it intact and accessible.
Korean scientists have designed a magnetically controlled wireless capsule that can efficiently and non-invasively deliver treatment drugs to patients who have gastrointestinal cancer.
Scientists analysing one of the largest genomic datasets of plants have discovered how the first plants on Earth evolved the mechanisms used to control water and ‘breathe’ on land hundreds of millions of years ago.
Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial infection that has become resistant to most of the antibiotics used to treat regular staph infections.
Coral reefs connected by larvae dispersal networks have been found to benefit local fisheries and biodiversity conservation, prompting recommendations to increase the protection of connected reefs.
