Research into the synthesis of new materials could lead to more sustainable and environmentally friendly items such as solar panels and light emitting diodes (LEDs). Scientists have developed a colloidal synthesis method for alkaline earth chalcogenides. This method allows them to control the size of the nanocrystals in the material and study the surface chemistry of the nanocrystals.

Aggregates of the protein alpha-synuclein spread in the brains of people with Parkinson's disease through a cellular waste-ejection process, suggests a new study.

In lab experiments, researchers observed a molecule called EGCG break up tau tangles extracted from Alzheimer's disease brain tissue EGCG does not, however, easily penetrate the human brain. They found two other molecules -- CNS-11 and CNS-17 -- that work like EGCG to stop tangles spreading cell to cell but are better leads for drugs.

Researchers have uncovered a novel pathway that explains how cancer cells become resistant to chemotherapies, which in turn offers a potential solution for preventing chemo-resistance.

The zebrafish serves as a model organism for researchers around the world: it can be used to study important physiological processes that also take place in a similar form in the human body. It is therefore routinely used in the search for possible active substances against diseases. Researchers have now described an innovative way to do this. In this process, the larvae fish are made a bit more...

A new study links an amphibian die-off in Costa Rica and Panama with a spike in malaria cases. The study demonstrates the importance of biodiversity to human health.

Researchers introduce a new neurocomputational model of the human brain that could bridge the gap in understanding AI and the biological mechanisms underlying mental disorders.

Does eye-contact always attract attention? Not in every case, as a research team has recently shown. Why not? Because context matters.

Biologists investigated whether octopuses preferred certain arms over others when hunting, rather than using each arm equally. No matter what type of prey came by, each octopus attacked using the second arm from the middle.

A study of moles reveals that cold weather -- not lack of food -- drives the rare phenomenon of reversible brain shrinkage in mammals.

Genetic variation affecting developmental genes not previously linked to urethral development may contribute to a congenital condition that is the most common cause of kidney failure in young males, a new study suggests.

Scientists have shown how tumor cells evade immunotherapy by generating unique, temporary cell-in-cell structures, where the inner cells remain in tact and can return to single tumor cells.

A topical gel that blocks the receptor for a metabolic byproduct called succinate treats gum disease by suppressing inflammation and changing the makeup of bacteria in the mouth, according to a new study.

Scientists explore how digital health solutions can expand audiology services in clinical and research settings. Audiology assessment via telehealth would allow patients to access care while a specialist is located hundreds of miles away and, as a research tool, telehealth would allow for more representative and decentralized data on hearing, without compromising results. The team is currently...

Scientists have uncovered a mechanism by which certain breast cancer cells regulate their own metastases, fuel dissemination from the original tumor site, and determine routes to invade distant organs such as the lungs, according to a new study.

A large-scale study has identified alarming rates of depression and PTSD among Flint, Michigan residents five years after their water crisis began. The public-works environmental disaster is over in some senses, but psychological recovery may be longer in coming.

A new passive cooling system relies on evaporation and radiation and requires no electricity. The device can provide up to about 19 degrees Fahrenheit (9.3 degrees Celsius) of cooling from the ambient temperature, to help keep food fresh longer or supplement air conditioning.

Fungal pathogens have a major global impact upon human health -- they are often difficult to diagnose and treat, and there is an urgent need for better diagnostics and more effective antifungal treatments. Using newly developed imaging technologies, researchers have now revealed how Candida albicans, a common fungus, evades immune responses. According to the researchers this involves an...

A research group has found that sensory neurons play an important role in human skin pigmentation and physiology. Specifically, the neurons secrete a protein known as Repulsive Guidance Molecule B (RGMB), which stimulates melanocytes (the cells in skin that produce melanin, which is responsible for skin coloration). This study could lead to the development of new drugs to treat pigmentation...

With autocorrect and auto-generated email responses, algorithms offer plenty of assistance to help people express themselves. But new research shows people who rely on algorithms for assistance with language-related, creative tasks didn't improve their performance and were more likely to trust low-quality advice.

Scientists have shown that high-fat diets can cause rapid changes in the bone marrow of mice, driving the production of inflammatory immune cells, according to new findings.

Researchers have made a breakthrough -- discovering new, natural sweeteners in citrus for the first time.

Researchers have developed a new mathematical technique to begin to understand how a cell's nucleus is organized. They hope this understanding will expose vulnerabilities that can be targeted to reprogram a cell to stop cancer or other diseases.

Across the world, specialists are working on implementing quantum information technologies. One important path involves light: Looking ahead, single light packages, also known as light quanta or photons, could transmit data that is both coded and effectively tap proof. To this end, new photon sources are required that emit single light quanta in a controlled fashion -- and on demand. Only recently...
