Scientists discover the enzymes responsible for the production of one of the most toxic and fast-acting neurotoxins associated with freshwater harmful algal blooms in lakes and ponds. The discovery revealed that guanitoxin-producing cyanobacteria are more prevalent than originally known in the United States, opening the possibility for new molecular diagnostic testing to better inform and protect the public from this natural freshwater toxin.

A groundbreaking study has found the underlying cause and a potential treatment for infantile spasms -- intractable epilepsy common in babies and with limited treatment options.

Detecting these T cells may lead to diagnostics to better detect heart disease--and disease severity--through a blood sample. The knowledge also brings researchers closer to developing a vaccine that dampens this dangerous immune cell activity to prevent atherosclerosis.

Unlike fictional laser swords, real laser beams do not interact with each other when they cross -- unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing can give rise to beams with changed colors and directions.

A team found flaws in previous research that purported to show meditation could alter the brain's structure.

New research could lead to better treatment options for a rare but very lethal type of bacterial infection.

Researchers have reported a nano-sized neuromorphic memory device that emulates neurons and synapses simultaneously in a unit cell, another step toward completing the goal of neuromorphic computing designed to rigorously mimic the human brain with semiconductor devices.

Difficult social and legal conditions are stress factors for same-sex families, but do not affect the behavior of children and young people with same-sex parents, new research suggests.

Researchers have reported new evidence that cognitive abnormalities seen in neuropsychiatric disorders such as schizophrenia may be traceable to altered activity in the thalamus during adolescence, a time window of heightened vulnerability for schizophrenia.

Two recent discoveries may help lead to new ways to treat patients with Allan-Herndon-Dudley syndrome (AHDS), a brain development disorder that causes severe intellectual disability and problems with movement.

Most research looking at the impact of climate change on human life has focused on how extreme weather events affect economic and societal health outcomes on a broad scale. Yet climate change may also have a strong influence on fundamental daily human activities -- including a host of behavioral, psychological, and physiological outcomes that are essential to wellbeing. Investigators now report that increasing ambient temperatures negatively impact human sleep around the globe.

Scientists have uncovered how one type of T cell creates two genetically identical, but functionally different, daughter cells.

Scientists discover superconductivity and charge density waves are intrinsically interconnected at the nanoscopic level, a new understanding that could help lead to the next generation of electronics and computers.

Scientists have described a novel preclinical drug that could have the potential to combat depression, brain injury and diseases that impair cognition. The drug, which notably is brain-permeable, acts to inhibit the kinase enzyme Cdk5.

A research team has mapped out the development and genetic trajectory of previously understudied macrophages associated with the central nervous system. Among other things, the team found that meningeal macrophages are formed during gestation and develop in the same way as microglia, while perivascular macrophages develop after birth. Their new insights could pave the way for better understanding the origins and mechanisms behind leading brain-related pathologies such as Alzheimer's disease.

According to a new study, long-term insomnia symptoms can pose a risk of poorer cognitive functioning later in life. This is another reason why insomnia should be treated as early as possible.

Researchers shed light on the way Quetzalcoatlus would have flown, finding that the dinosaur's flying dynamics were actually very different to how it has been depicted in popular culture.

Real data gathered by volunteers was combined with new computer models for the first time to reveal which UK moth species are struggling to expand into new regions and the landscape barriers restricting their movement. Farmland and suburban moths were found to be struggling most, with hills or regions with variable temperatures acting as barriers. This has implications for British wildlife being forced to move to adapt to climate change, and habitat restoration in challenging areas could help wildlife movement.

A substantial part of the trade in blood pythons in Indonesia is illegal and underreported, a new study has found. The study found no convincing evidence that the harvest of blood pythons in the area is sustainable. Even though the harvest and trade of the species are regulated by a quota system, misdeclared, underreported and illegal trade remain a serious challenge to its sustainable exploitation.

Scientists have shown an existing drug may reduce damage after spinal cord injury, by blocking the inflammatory response in the spinal cord.

Scientists have been relentlessly working on understanding the fundamental mechanisms at the base of high-temperature superconductivity with the ultimate goal to design and engineer new quantum materials superconducting close to room temperature.

Many wild salmon populations in B.C. have experienced substantial declines over the last three decades. New research can help chart a course towards better protection of wild salmon.
