Chemist's new process fast-tracks drug treatments for viral infections and cancer

Saturday August 8th, 2020 12:57:56 PM
Discovering antiviral and anticancer drugs will soon be faster and cheaper thanks to new research.

Deep-sea misconceptions cause underestimation of seabed-mining impacts

Saturday August 8th, 2020 12:57:54 PM
A new publication on the impacts of deep-seabed mining by 13 prominent deep-sea biologists seeks to dispel scientific misconceptions that have led to miscalculations of the likely effects of commercial operations to extract minerals from the seabed.

Curious clues in war between bacteria in cystic fibrosis patients

Saturday August 8th, 2020 12:57:52 PM
Several different kinds of bacteria can cause lung infections in people with cystic fibrosis. Pseudomonas aeruginosa, which can cause pneumonia, typically infects infants or young children and persists for life, while Burkholderia cepacia complex species only infect teenagers and adults. Although Burkholderia infections are rare, when they do take hold, they are deadly. Now, scientists have discovered a reason for this pathogen's apparent age discrimination.

Predicting drought in the American West just got more difficult

Saturday August 8th, 2020 12:57:50 PM
A new study of more than 1,000 years of North American droughts and global conditions found that forecasting a lack of precipitation is rarely straightforward.

Decline in plant breeding programs could impact food security

Friday August 7th, 2020 07:36:53 PM
A team of scientists led by a horticulture professor who leads a pome fruit (apples and pears) breeding program, found that public plant breeding programs are seeing decreases in funding and personnel.

Advance in programmable synthetic materials

Friday August 7th, 2020 07:36:48 PM
DNA information is stored in a sequence of chemical building blocks; computers store information as sequences of zeros and ones. Researchers want to transfer this concept to artificial molecules. Researchers have taken another step toward encoding information in the sequence of metal atoms in metal-organic frameworks (MOFs), showing how to read the sequence. Multivariate MOFs could encode digital information, but also conduct programmed chemical modifications or controlled drug release.

Layer of nanoparticles could improve LED performance and lifetime

Friday August 7th, 2020 07:36:44 PM
Adding a layer of nanoparticles to LED designs could help them produce more light for the same energy, and also increase their lifetime.

Highly sensitive dopamine detector uses 2D materials

Friday August 7th, 2020 07:36:43 PM
A supersensitive dopamine detector can help in the early diagnosis of several disorders that result in too much or too little dopamine, according to new research.

Authors' 'invisible' words reveal blueprint for storytelling

Friday August 7th, 2020 07:36:41 PM
The ''invisible'' words that shaped Dickens classics also lead audiences through Spielberg dramas. And according to new research, these small words can be found in a similar pattern across most storylines, no matter the length or format.

Materials science researchers develop first electrically injected laser

Friday August 7th, 2020 05:19:22 PM
Materials science researchers have demonstrated the first electrically injected laser made with germanium tin. Used as a semiconducting material for circuits on electronic devices, the diode laser could improve micro-processing speed and efficiency at much lower costs.

New test better predicts which babies will develop type 1 diabetes

Friday August 7th, 2020 05:19:18 PM
A new approach to predicting which babies will develop type 1 diabetes moves a step closer to routine testing for newborns which could avoid life-threatening complications.

Sugar-based signature identifies T cells where HIV hides despite antiretroviral therapy

Friday August 7th, 2020 05:19:17 PM
Scientists may have discovered a new way of identifying and targeting hidden HIV viral reservoirs during treatment with antiretroviral therapy (ART). These findings may have translational implications for improving the long-term care of HIV positive people.

Strong link found between abnormal liver tests and poor COVID-19 outcomes

Friday August 7th, 2020 05:19:12 PM
Researchers found that patients with COVID-19 presented with abnormal liver tests at much higher rates than suggested by earlier studies. They also discovered that higher levels of liver enzymes -- proteins released when the liver is damaged -- were associated with poorer outcomes for these patients, including ICU admission, mechanical ventilation, and death.

Newly discovered mutation could point to heart disease therapeutic target

Friday August 7th, 2020 05:19:10 PM
New work identifies a potential therapeutic target for clogged arteries and other health risks that stem from an excess of harmful fats in the bloodstream. The study opens the door for the design of more specific MTP inhibitors that could reduce circulating triglyceride levels without the risk of unpleasant and serious side effects in the intestines and liver.

Updating Turing's model of pattern formation

Friday August 7th, 2020 03:19:42 PM
New research revisits the Turing instability mechanism; proving mathematically how the instabilities which give rise to patterns can occur through simple reactions, and in widely varied environmental conditions.

Measuring electron emission from irradiated biomolecules

Friday August 7th, 2020 03:19:40 PM
Researchers have successfully determined the characteristics of electron emission when high-velocity ions collide with adenine - one of the four key nucleobases of DNA.

Pinpointing the cells that keep the body's master circadian clock ticking

Friday August 7th, 2020 03:19:38 PM
Scientists have developed a genetically engineered mouse and imaging system that lets them visualize fluctuations in the circadian clocks of cell types in mice. The method gives new insight into which brain cells are important in maintaining the body's master circadian clock. But they say the approach will also be broadly useful for answering questions about the daily rhythms of cells throughout the body.

Scientists use CRISPR to knock down gene messages early in development

Friday August 7th, 2020 03:19:35 PM
Researchers have harnessed the technology to target gene messages (messenger RNA) involved in early vertebrate development.

Florida current is weaker now than at any point in the past century

Friday August 7th, 2020 03:19:29 PM
A key component of the Gulf Stream has markedly slowed over the past century -- that's the conclusion of a new research paper.

Atlantic hurricanes linked to weather system in East Asia

Friday August 7th, 2020 03:19:26 PM
Climate researchers have found a link between hurricanes that form in the Atlantic Ocean - and threaten the United States - and a weather system in East Asia. A jet stream originating in East Asia carries an atmospheric wave to the Atlantic Ocean that affects wind shear - a key element in whether tropical storms develop.
