Protein engineers navigate toward more targeted therapeutics

More than a third of FDA-approved drugs work by targeting a G protein-coupled receptor, or GPCR. The human body has more than 800 types of GPCRs that provide cells with information about the external environment to calibrate responses. Drugs that either block or activate GPCRs are used to treat a wide range of diseases including hypertension, pain and inflammation. Most drugs bind to the outside...

Researchers prepare for quantum sensing in outer space

As part of a new NASA Quantum Pathways Institute consisting of a multi-university research team, UC Santa Barbara professor of electrical and computer engineering Daniel Blumenthal will help to build technology and tools to improve measurement of important climate factors by observing atoms in outer space.

Integrated grafting system developed for passion fruit plantlets

Passion fruit has become an important fruit crop in Taiwan and Southeast Asia due to its special taste and nutrient-rich flesh. However, it is seriously harmed by viruses, blight, and brown spot diseases. As a result of virus disease, producers have to renew passion fruit plantlets every year to ensure yield and fruit quality.

Modeling superfast processes in organic solar cell material

In organic solar cells, carbon-based polymers convert light into charges that are passed to an acceptor. This type of material has great potential, but to unlock this, a better understanding is needed of the way in which charges are produced and transported along the polymers.

Research team develops multifunctional vortex beam for UV-visible spectra

The Fourth Industrial Revolution is driving exponential growth in data transmission, and cost-effective, ultrafast, and compact optical communication technologies are urgently needed to manage the exploding data transmission volume. Vortex beams, which exhibit a swirling shape around the axis of propagation, have the potential to increase the amount of information that can be stored at the same...

Testing the ocean's chemistry and climate impact

A team of graduate students and researchers from the University of Miami is navigating through the northern Atlantic Ocean on an international research voyage to learn more about how the ocean is changing through time.

Researchers document 55 more white sharks in Cape Cod waters

The scientific nonprofit that tracks the white shark population in Cape Cod waters identified 55 sharks never before documented in the area during its most recent research season, but experts say that's no reason for tourists who flock to the vacation hotpsot every summer to be afraid of going in the water.

How does Idaho count wolves? Critics say state uses 'smoke and mirrors,' misleads public

As a scruffy gray-and-brown wolf stood in a grassy Idaho clearing, it fixed its gaze straight ahead. Another dark wolf trotted down a muddy dirt road. A third stepped over gravelly terrain, its mouth open as it panted in the sun. Motion-triggered cameras, placed by the Idaho Department of Fish and Game, snapped photos of the wild animals along trails. Later, the agency would use those photos to...

Excavations reveal copper deposits that made Cyprus one of the most important Late Bronze Age trade hubs

Excavations led by researchers from the University of Gothenburg show that the coveted metal copper and a sheltered location turned the Cypriot village of Hala Sultan Tekke into one of the most important trade hubs of the Late Bronze Age. The researchers' study published in the Journal of Archaeological Science: Reports confirms the importance of the Bronze Age city in the first period of...

Long noncoding RNA TARL can help fish resist Vibrio infection by regulating the stability of TAK1

In a study published in the journal Science China Life Sciences, Miichthys miiuy in teleost was taken as the research object to explore whether lncRNA can play a regulatory role in the process of teleost resisting susceptible pathogenic Vibrio infection. And the researchers found that the expression of lncRNA TARL was up-regulated in the spleen tissue of M. miiuy stimulated by LPS.
