A new study conducted by the researchers at the University of Liverpool reveals how the ancient photosynthetic organisms - cyanobacteria - evolve their photosynthetic machinery and organise their photosynthetic membrane architecture for the efficient capture of solar light and energy transduction.

Underwater recordings show that endangered blue whales are present and singing off the southwest coast of India. This extends the range of a known song type by 1,000 kilometers, into Indian waters. The results suggest that conservation measures should include this region.

For older adults, participating in social activities can protect against physical and mental signs of aging, but it may also pose risks, especially for women.

Preliminary results of a new study show that a wearable electroencephalogram device that gathers data from the ear measures sleep as reliably as traditional EEG electrodes attached to the scalp.

People who have a high sensation-seeking personality trait may be more likely to develop an addiction to cocaine, according to a Rutgers study.

The routes and schedules of public transit, the presence or absence of sidewalks, the availability of different transportation options, and the design of highways that divide cities--these are examples of aspects of transportation systems that can profoundly impact underserved communities' access to basic needs like jobs, health care, education and even food.

In a review published in the journal Cancer Cell of 200 patients with a wide spectrum of cancer diagnoses, researchers found that after full vaccination, 94%of patients overall demonstrated seroconversion, which was determined by the presence of antibodies to the SARS-CoV-2 spike protein. Response rates were very high among patients with solid tumors and were lower in people with certain blood cancers, but even the majority of those patients mounted an immune response.

University of Illinois Chicago researchers studying birth outcomes in marmoset monkeys found there were no adult maternal characteristics like age or weight gain during pregnancy to predict stillbirth or early neonatal death, but that a mother's birth weight or litter size were associated with early neonatal death.

Considering local stakeholder conceptions of fairness in conservation is critical. Current conservation practice and policy in low- and middle-income countries are shaped by rich Western countries, which means they are underpinned by Western ideas about fairness.

Researchers at Staffordshire University have developed a new low-cost method to help prevent life-threatening foot ulcers in diabetic patients.

Smokers needed their blocked arteries fixed nearly a decade earlier than non-smokers, and patients with obesity underwent these procedures four years earlier than non-obese patients, according to a new study from across Michigan.

New research in AGU's journal Geophysical Research Letters used a system for monitoring nuclear tests to track the infrasound from 1,001 rocket launches, identifying the distinctive sounds from seven different types of rockets. In some cases, like the Space Shuttle and the Falcon 9, the researchers were also able to identify the various stages of the rockets' journey (audio available).

Researchers from the University of Maryland School of Medicine (UMSOM) and their colleagues found that nearly 20 percent of patients with unexplained sudden cardiac death - most of whom were under age 50 - carried rare genetic variants. These variants likely raised their risk of sudden cardiac death.

Purdue University engineers have developed a new spray/sewing method to transform any conventional cloth items into battery-free wearables that can be cleaned in the washing machine.

A new study led by Penn paleontologist Aja Carter documents distinct patterns in how early amphibians' spines evolved. Certain modifications, the research team found, correlated with the animals' habitat: terrestrial or aquatic.

Russian scientists have found a way to increase photoluminescence in silicon, the notoriously poor emitter and absorber of photons at the heart of all modern electronics. This discovery may pave the way to photonic integrated circuits, boosting their performance.

Researchers from York University and the University of British Columbia have found social media use to be one of the factors related to the spread of COVID-19 within dozens of countries during the early stages of the pandemic.The researchers say this finding resembles other examples of social media misinformation ranging from the initial phase of vaccine rollout to the 2021 Capitol riot in the United States.

Small pieces of plastic are everywhere, stretching from urban environments to pristine wilderness. Left to their own devices, it can take hundreds of years for them to degrade completely. Catalysts activated by sunlight could speed up the process, but getting these compounds to interact with microplastics is difficult. In a proof-of-concept study, researchers reporting in ACS Applied Materials & Interfaces developed self-propelled microrobots that can swim, attach to plastics and break them down.

Chronic inflammation in the gut may propel processes in the body that give rise to Parkinson's disease, according to a study by scientists at Van Andel Institute and Roche.The study, published in Free Neuropathology, is the latest in a growing list that links the gut and the immune system to Parkinson's.
