Photosynthesis News and Research

RSS

Photosynthesis is a chemical process by which plants, some bacteria, and algae convert energy derived from sunlight to chemical energy. This is an important process for biological life on earth because it allows energy from sunlight to be harnessed and transferred into a form that can be utilized by organisms to fuel their activity.

Boston College chemists use nanowires to power photosynthesis

Harnessing the power of the sun has inspired scientists and engineers to look for ways to turn sunlight into clean energy to heat houses, fuel factories and power devices. While a majority of this research focuses on energy production, some researchers are looking at the potential uses of these novel solar technologies in other areas.

Scientists discover curious twist in chalcone-isomerase

A curious twist in a family of plant proteins called chalcone-isomerase recently was discovered by Salk Institute for Biological Studies scientist Joseph Noel and colleagues at Iowa State University led by Eve Wurtele.

Researchers uncover how phytoplankton release powerful toxins into environment

Each year, phytoplankton blooms known as "red tides" kill millions of fish and other marine organisms and blanket vast areas of coastal water around the world. Though the precise causes of red tides remain a mystery, a team of researchers in the United States and Spain has solved one of the main riddles about these ecological disasters by uncovering the specific mechanism that triggers phytoplankton to release their powerful toxins into the environment.

SonoPhoto Dynamic Therapy shows promise against squamous cell carcinoma

George Miller developed an ulcer on his bottom lip that began to bleed. His doctor sent cell scrapings to a pathologist, and diagnosed Miller with squamous cell carcinoma (SCC). According to TMD Limited, a medical tourism company, squamous cell carcinoma is the 2nd most common cancer in humans and other animals.

Sunscreen pills from coral

Researchers have found that coral does not suffer from sunburn despite living in shallow water in tropical areas, because it is able to produce its own “natural sunscreen”. By studying the compounds which protect it from UV rays, researchers hope to develop a tablet which can protect human skin and eyes without the need for dark glasses or sun cream. Scientists from King's College London said the first sunscreen pill could be available within five years.

More biodiversity needed to keep ecosystems functioning

The biological diversity of organisms on earth is not just something we enjoy when taking a walk through a blossoming meadow in spring; it is also the basis for countless products and services provided by nature, including food, building materials, and medicines as well as the self-purifying qualities of water and protection against erosion.

Sediments buried beneath the Black Sea contain ancient virus and host DNA

A scientist analyzing ancient plankton DNA signatures in sediments of the Black Sea has found that the same genetic populations of a virus and its algal host can persist--and coexist--for centuries.

Super-resolution microscopy technique reveals how and why cell's defenses fail against plague

Researchers at Sandia National Laboratories have developed a super-resolution microscopy technique that is answering long-held questions about exactly how and why a cell's defenses fail against some invaders, such as plague, while successfully fending off others like E.coli.

MIT develops new software to predict complex 3-D DNA structures

While the primary job of DNA in cells is to carry genetic information from one generation to the next, some scientists also see the highly stable and programmable molecule as an ideal building material for nanoscale structures that could be used to deliver drugs, act as biosensors, perform artificial photosynthesis and more.

Researchers develop hard X-ray laser to determine structure of biomolecules

Unraveling the molecular basis of life is an age-old quest of humanity. A breakthrough towards this goal was reported in a pair of studies published Feb. 3 in the scientific journal Nature, detailing a new method developed to determine structures of biomolecules based on diffraction from protein nanocrystals that are so small that they are not even visible under the microscope.

Study confirms human excrements contribute to water pollution

Every person emits the equivalent of approximately two tonnes of carbon dioxide a year from the time food is produced to when the human body excretes it, representing more than 20% of total yearly emissions. That is what a study by the Universidad de Almer-a says, confirming for the first time that human excrements contribute to water pollution, primarily with nitrogen and phosphorus.

Scientists determine tertiary structure of TehA membrane protein in Haemophilus bacteria

Proteins are molecular machines that transport substances, catalyze chemical reactions, pump ions, and identify signaling substances. They are chains of amino acids and the individual amino acid sequence is known for many of them. However, the functions a protein can carry out inside the cell are determined by the three-dimensional spatial structure of the protein. Establishing this so-called tertiary structure presents a great challenge to scientists.

ASU receives grant to unravel membrane proteins in host-pathogen interaction

Arizona State University has been awarded a $7.7 million grant for the next five years from the National Institute of General Medical Sciences, part of the National Institutes of Health, to unravel the structures of membrane proteins that play a key role in protection against infectious diseases.

Researchers explore range of potential new fuel sources in nature

On the long and difficult road toward a carbon-neutral source of transportation fuels, the U.S. Department of Energy is pursuing a diversified approach. This effort involves exploring a range of potential new fuel sources in nature: from plants that may serve as cellulosic feedstocks-fast-growing trees and perennial grasses on land-to oil-producing organisms in aquatic and other environments, such as algae and bacteria.
