PCR technology is a molecular diagnostics technology that detects target nucleic acids by amplifying the DNA amount. It has brought marked progress in the life sciences field since its development in 1984. This technology has recently become familiar to the public due to the COVID-19 pandemic, since PCR can detect nucleic acids that identify the COVID-19 virus. However, due to the technical nature of the PCR test, results cannot be immediately delivered. It takes at least 1 to 2 hours for the test as it requires repeated temperature cycles (60~95℃). Dr. ...

In a chemical reaction, molecules in different substances meet one another to form new molecules causing changes in the bonds of their atoms. The molecules collide at an extremely close distance—a nanometer or less—in an extremely short amount of time. This makes investigating the details of chemical reactions at the molecular scale difficult. Most experimental knowledge, used to explain single-molecule reaction dynamics, was obtained by studying reactions in gases. However, the overwhelming majority of chemical reactions take place in liquids, so elucidating single-molecule reaction dynamics in solution is an important challenge, with very few experimental ...

A team of researchers from the Keck School of Medicine of USC found that exposure to a mixture of synthetic chemicals found widely in the environment alters several critical biological processes, including the metabolism of fats and amino acids, in both children and young adults. The disruption of these biological processes is connected to an increased risk of a very broad range of diseases, including developmental disorders, cardiovascular disease, metabolic disease and many types of cancer.  Known as per- and polyfluoroalkyl substances, or PFAS, these man-made chemicals are used in a wide range of consumer and industrial products. PFAS are sometimes ...

(MIAMI, FL, FEB. 21, 2023) – To create the most effective, personalized treatment plans for patients with Hodgkin lymphoma or other cancers, scientists and clinicians need the clearest picture of the genetic changes leading to the cancer’s development. That picture, say scientists at Sylvester Comprehensive Cancer Center in the University of Miami Miller School of Medicine, comes into much better focus when whole genome sequencing – rather than the current standard, exome sequencing – is used to identify changes driving the cancer. Exome sequencing, which reads only protein-coding genes, can detect some specific mutations and other variants that propel cancers, ...

Eurasian spruce bark beetles (Ips typographus) burrow into the bark of Norway spruce (Picea abies) trees where they mate and lay their eggs. Major outbreaks in Europe have decimated millions of hectares of conifer forests. The beetles preferentially attack trees that are already infected with symbiotic fungi (such as Grosmannia penicillata), which is thought to weaken host trees and break down their chemical defenses, allowing the beetles to successfully develop in the bark. To investigate the chemical signals ...

The mass outbreaks of bark beetles observed in recent years have caused shocking amounts of forest damage throughout Germany. As reported by the Federal Statistical Office in July 2022, more than 80% of the trees that had to be felled in the previous year were damaged by insects. The damaged timber felled due to insect damage amounted to more than 40 million cubic meters. One of the main pests is the European spruce beetle Ips typographus. In the Thuringian Forest and the Harz Mountains, for example, the beetle, which is only a few millimeters long, encountered spruce monocultures that had already been weakened by high temperatures and extended ...

Takeaki Ozawa and his team from the University of Tokyo reveal the metabolic reactions upon activating an enzyme called Akt2. In doing so, they reveal the inner workings of insulin-regulated metabolism. The findings lead the way for Akt2-targeting therapeutics for diabetes and metabolic disorders.  It takes energy to do anything—even to exist. You can metabolize food to convert glucose into energy: thanks to many cascades of molecular reactions within your cells. As soon as you eat, your pancreas secretes insulin hormone, which starts ...

SAN FRANCISCO, CA—February 21, 2023—Of all the known genetic risk factors for late-onset Alzheimer’s disease, the strongest is a gene for the protein called ApoE4. People with one copy of this gene are 3.5 times more likely, on average, to develop Alzheimer’s than others, and those with two copies face a 12-fold increased risk. However, exactly how ApoE4 boosts the risk of Alzheimer’s remains unclear. Multiple types of cells in the brain make ApoE4—some of it is produced by neurons, but other brain cells called glia make it in higher quantities. For that reason, most prior research on this protein has focused on ...

Today, there are many emerging applications for small satellite constellations, ranging from space-borne networks to environmental monitoring. However, small satellites have special needs when it comes to transmitter (TX) technology. For one, they have stringent limitations on power consumption as they draw energy from solar panels and cannot easily dissipate generated heat. Moreover, small satellites need to communicate with fast-moving targets that can be over a thousand kilometers away. Thus, they require efficient and precise beam steering capabilities to direct most of the transmitted power ...

A database updated in 2022 reported around 4,852 active satellites orbiting the earth. These satellites serve many different purposes in space, from GPS and weather tracking to military reconnaissance and early warning systems. Given the wide array of uses for satellites, especially in low Earth orbit (LEO), researchers are constantly trying to develop better ones. In this regard, small satellites have a lot of potential. They can reduce launch costs and increase the number of satellites in orbit, providing a better network with wider coverage. ...

ATP, the compound essential for the functioning of photosynthetic organisms such as plants, algae, and cyanobacteria, is produced by an enzyme called “chloroplast ATP synthase” (CFoCF1). To control ATP production under varying light conditions, the enzyme uses a redox regulatory mechanism that modifies the ATP synthesis activity in response to changes in the redox state of cysteine (Cys) residues, which exist as dithiols under reducing (light) conditions, but forms a disulfide bond under oxidizing (dark) conditions. ...

Bicycles whirr by, students rush to class, staff and faculty are grabbing lunch or coffee on the go — and sheep graze the grassy knolls among the traffic, bleating every now and then. The grazing is their job. The 25 wooly sheep who seasonally — for the past two years — leave their University of California, Davis, barns to nibble on lawns at various central campus locations, are doing much more than mowing, fertilizing and improving the ecosystem. The sheep also are improving people’s mental health. The sheep — four breeds of Suffolk, Hampshire, Southdown and Dorset — first took on this role in 2021, when COVID-19 ...
