The bacterium Pseudomonas aeruginosa is the leading cause of hospital-acquired infections. The pathogen is resistant to many antibiotics so treating those infections, particularly in patients with compromised immune systems, is difficult.
A new study from UT has identified certain chemical receptors in cells that could deceive the bacteria and improve patient response to drugs.
The study was published this week in the Proceedings of the National Academy of Sciences.
Scientists with the SOLAR-JET Project have demonstrated the first-ever entire process to make kerosene, the jet fuel used by commercial airlines, using a high-temperature thermal solar reactor to create syngas. Shell Global Solutions in Amsterdam refined the solar syngas into jet fuel, using the Fischer-Tropsch method.
Thermochemical solar fuel manufacturing would be an energy industry with a life of centuries, rather than decades. The feedstock of sunlight, carbon dioxide and water is essentially unlimited.
First genetic mutation discovered to protect against multiple aspects of aging in humans
Amish carrying the mutation live more than 13 percent longer to 85 years old instead of 75 for those who don't carry the mutation
Longevity drug developed from this research is being tested in humans
Closely related form of drug being developed as topical treatment for baldness
So, you thought the fictional people-eating great white shark in the film "Jaws" had a powerful bite.
But don't overlook the mighty mouth of the parrotfish - its hardy teeth allow it to chomp on coral all day long, ultimately chewing and grinding it up through digestion into fine sand. That's right: Its "beak" creates beaches. A single parrotfish can produce hundreds of pounds of sand each year.
With less than 25,000 breeding pairs in existence today, it is an uphill battle for the African Penguin, which calls South Africa home. The 60 percent drop in their population since 2001 has put them on the endangered species list by the International Union for Conservation of Nature. In some South African colonies, the drop in population has been as high as 80 percent. Competition with fisheries, oil spills, climate change, diseases and predators are all contributing factors in their dramatic decline.
To humans, being right-handed or left-handed plays an important role. The majority favours the right side of their bodies, while only about three per cent of people innately use both hands equally well. Preferring one side of the body over another is not unique to humans: the phenomenon occurs in the animal kingdom as well, for instance in great apes or birds, although their "handedness" is typically not as obvious as it is in humans. "Handedness" is particularly pronounced in cichlid fish of the species Perissodus microlepis, which is endemic to Lake Tanganyika in Africa.
What does the general public know about climate engineering, and what do they think about what they know? These were questions asked by researchers from Linköping University, together with researchers from Japan, the US and New Zealand.
Scientists from RUDN University and the Ivan Franko National University of Lviv have found a way to produce aromatic rings in organic compounds in three stages. These stages proceed successively in one-pot conditions and at room temperature. Now analogues of hormones, steroids, some sugars, terpenes and other complex organic substances can be synthesized faster and at softer conditions. The paper was published in Tetrahedron Letters.
A new study by researchers at Loma Linda University Health has found that eating nuts on a regular basis strengthens brainwave frequencies associated with cognition, healing, learning, memory and other key brain functions. An abstract of the study -- which was presented in the nutrition section of the Experimental Biology 2017 meetings in San Diego, California, and published in the FASEB Journal.
Not only are immediate friendships an important aspect of our life, but so are our extended acquaintances and friends' of friends connections, according to new Oxford University research. The findings shed light on how social networks can evolve, by showing that complex social patterns observed across the animal kingdom may be simpler than they appear.
These relationships are known as 'indirect social connections', and show where each individual is positioned within the overall social network.
