Where do 'Hawaiian box jellies' come from?
An insightful cross-disciplinary team, working for over a decade, published a study recently revealing that a key number of hours of darkness during the lunar cycle triggers mature 'Hawaiian box jellyfish' (Alatina alata) to swim to leeward O'ahu shores to spawn. 05/20/2022 06:12 PM
Unraveling a perplexing explosive process that occurs throughout the universe
Novel simulation brings extraordinary fast radio bursts into the laboratory in a way once thought impossible. 05/20/2022 06:12 PM
Researchers unveil a secret of stronger metals
Researchers determined exactly what happens as crystal grains in metals form during an extreme deformation process, at the tiniest scales, down to a few nanometers across. The findings could lead to better, more consistent properties in metals, such as hardness and toughness. 05/20/2022 06:12 PM
Deciphering the biosynthetic gene cluster for potent freshwater toxin
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. 05/20/2022 02:47 PM
Study discovers an underlying cause for infantile spasms and points to a novel therapy
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. 05/20/2022 02:47 PM
PFAS chemicals do not last forever
Once dubbed 'forever chemicals,' per-and polyfluoroalkyl substances, or PFAS, might be in the market for a new nickname. Adding iodide to a water treatment reactor that uses ultraviolet (UV) light and sulfite destroys up to 90% of carbon-fluorine atoms in PFAS forever chemicals in just a few hours, reports a new study led by environmental engineers. The addition of iodide accelerates the speed of the reaction up to four times, saving energy and chemicals. 05/20/2022 02:47 PM
Haywire T cells attack protein in 'bad' cholesterol
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. 05/20/2022 02:47 PM
Light pollution can disorient monarch butterflies
Biologists say nighttime light pollution can interfere with the remarkable navigational abilities of monarchs, which travel as far as Canada to Mexico and back during their multi-generational migration. Researchers found that butterflies roosting at night near artificial illumination such as a porch or streetlight can become disoriented the next day because the light interferes with their circadian rhythms. Artificial light can impede the molecular processes responsible for the butterfly's remarkable navigational ability and trigger the butterfly to take wing when it should be resting. 05/20/2022 02:46 PM
Mixing laser- and x-ray-beams
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. 05/20/2022 02:46 PM
New research shows no evidence of structural brain change with short-term mindfulness training
A team found flaws in previous research that purported to show meditation could alter the brain's structure. 05/20/2022 02:46 PM
Neuromorphic memory device simulates neurons and synapses
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. 05/20/2022 01:29 PM
Children with same-sex parents are socially well-adjusted
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. 05/20/2022 01:29 PM
Study links thalamus inhibition in adolescence to long-lasting cortical abnormalities
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. 05/20/2022 01:28 PM
New research challenges established ideas about infant crying
A research project provides a new understanding of what can be defined as normal and excessive crying among infants. 05/20/2022 01:28 PM
Climate change likely to reduce the amount of sleep that people get per year
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. 05/20/2022 01:28 PM
Function follows form in plant immunity
Scientists have discovered a novel biochemical mechanism explaining how immune proteins defend plants against invading microorganisms. 05/20/2022 01:28 PM
Killer T vs. memory -- DNA isn't destiny for T cells
Scientists have uncovered how one type of T cell creates two genetically identical, but functionally different, daughter cells. 05/20/2022 01:28 PM
Research reveals surprising inactivation mechanism for a voltage-gated ion channel
The study from St. Jude Children's Research Hospital presents a new understanding of how a VGIC, crucial for the communication of neurons and muscle cells, can become unresponsive. 05/20/2022 01:28 PM
Superconductivity and charge density waves caught intertwining at the nanoscale
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. 05/20/2022 01:28 PM
Novel preclinical drug could have potential to combat depression, brain injury and cognitive disorders
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. 05/20/2022 01:28 PM
