It is in industrialised countries and regions of the world where one can find the highest concentrations of lead, the world's most widespread neurotoxical accumulative metal. Thus, it was presumed that the Amazon, the world's largest expanse of tropical rainforest containing the highest levels of biocultural and cultural diversity, would contain a low amount of urban or industrial contaminants due to its remoteness and low human impact.

Some older adults without noticeable cognitive problems have a harder time than younger people in separating irrelevant information from what they need to know at a given time, and a new Johns Hopkins University study could explain why.

The findings offer an initial snapshot of what happens in the brain as young and old people try to access long-term memories, and could shed light on why some people's cognitive abilities decline with age while others remain sharp.

BEER-SHEVA, Israel...August 5, 2019 - Mankai, a new high-protein aquatic plant strain of duckweed, has significant potential as a superfood and provides glycemic control after carbohydrate consumption, a team of researchers from Ben-Gurion University of the Negev (BGU) has determined.

A new team-based model for intensive care unit (ICU) pharmacists, developed by Rutgers and RWJBarnabas Health System, resolves a common dilemma for hospitals and improves care for critically ill patients.

Given that they generate hardly any greenhouse gases, are undemanding, nutritious and fast growing, insects have generated a lot of hype in recent years. They are touted as the superfood of the future - cheap suppliers of protein that can even decompose all kinds of residual products.

Tomato yellow leaf curl disease (TYLCD) caused by tomato yellow leaf curl virus-like viruses is the most destructive disease of tomato, causing severe damage to crops worldwide and resulting in high economic losses. To combat this disease, many farmers opt for intensive application of insecticides. However, this practice is frequently ineffective and has a negative impact on the environment and human health.

HOUSTON - (Aug. 5, 2019) - Paper is at the heart of an experimental device developed by Rice University bioengineers to study heart disease.

They are using paper-based structures that mimic the layered nature of aortic valves, the tough, flexible tissues that keep blood flowing through the heart in one direction only. The devices allow the engineers to study in detail how calcifying diseases slow or stop hearts from functioning.

Bottom Line: Incorporation of pan-cancer microsatellite instability (MSI) detection into the 74-gene panel Guardant360 liquid biopsy assay showed high concordance with matched tissue samples in nearly 1,000 patients.

PITTSBURGH, Aug. 5, 2019 - Scientists at Magee-Womens Research Institute (MWRI), collaborating with clinicians at UPMC Magee-Womens Hospital and UPMC Children's Hospital of Pittsburgh report two cases in which young transgender women attempted to recover their fertility after starting and stopping gender-affirming medications.

A genetic mutation that slowed down the development of the prefrontal cortex (PFC) in two or more children may have triggered a cascade of events leading to acquisition of recursive language and modern imagination 70,000 years ago.

Adults are really good at paying attention only to what you tell them to - but children don't ignore anything.

That difference can actually help children do better than adults in some learning situations, a new study suggests.

Researchers surprised adults and 4- and 5-year-old children participating in the study by making information that was irrelevant at the beginning of the experiment suddenly important for a task they had to complete.

A new analysis of data on more than 900 Baltimore adults by Johns Hopkins Medicine researchers has linked stressful life experiences among middle-aged women -- but not men -- to greater memory decline in later life.

The researchers say their findings add to evidence that stress hormones play an uneven gender role in brain health, and align with well-documented higher rates of Alzheimer's disease in women than men.

Drone footage has shown never-before seen behaviour of two leopard seals sharing food.

Despite being considered a charismatic and enigmatic Antarctic predator, leopard seals are normally thought of as being solitary.

They are largely intolerant of each other but can be forced to hunt alongside one another when congregating in areas of abundant prey.

A new study analysing the previously unseen footage reports up to 36 seals seen feeding at the same king penguin colony in South Georgia.

A small team of researchers at Indiana University has created the first global map of labor flow in collaboration with the world's largest professional social network, LinkedIn. The work is reported in the journal Nature Communications.

One of the most dangerous risks expectant mothers face as their delivery date approaches is a surprisingly common condition with a little-known name: placental accreta.

In normal childbirth, the placenta that sustains fetal development during pregnancy is delivered shortly after the newborn infant. But sometimes, the placenta becomes so deeply attached to the woman's uterus that it cannot be removed without causing massive, sometimes fatal bleeding. In many cases, the emergency surgery needed to save the mother's life can leave her unable to have any more children.
