DNA vaccine for tick-borne disease ‘SFTS’ confers protection against lethal infection in ferrets

A KAIST research team reported the development of a DNA vaccine for Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV) which completely protects against lethal infection in ferrets.

New optical technology heralds exciting potential for mammalian behavioral studies

In an article published in the peer-reviewed, open-access SPIE publication Neurophotonics, "A multi-site microLED optrode array for neural interfacing," researchers present an implantable optrode array capable of exciting below-surface neurons in large mammal brains at two levels, both by structured-light delivery and large-volume illumination.

Cancer cells ‘corrupt’ their healthy neighbors to support tumor growth

The healthy cells immediately surrounding a tumor become more stem cell-like and support cancer growth, reveals a new study published in Nature.

MUSC researchers narrow down risk of preeclampsia to a specific phenotype

The force of blood traveling through your arteries and veins determines much of your heart health. High blood pressure can lead to heart disease, heart failure, heart attack, stroke and chronic kidney disease, and when it's coupled with type 1 diabetes and pregnancy, it can put both the mother and the baby at risk.

Researchers shed new light on how the brain constructs itself

The cerebral cortex acts as the control center of our cognitive processes. During embryogenesis, dozens of types of neurons with distinct functions come together to form the circuits that drive our thoughts and actions.

Using 3D nanoparticle printing to fabricate ultra-high density neural probes

Carnegie Mellon University's Rahul Panat, an associate professor of mechanical engineering, and Eric Yttri, an assistant professor of biological sciences, have received a $1.95 million R01 grant from the National Institutes of Health to use a low-cost, rapid additive manufacturing method to create a new class of high-density neural probes to record neurological data.

A single cholesterol-derived molecule promotes adiposity

A single cholesterol-derived molecule, called 27-hydroxycholesterol (27HC), lurks inside your bloodstream and will increase your body fat, even if you don't eat a diet filled with red meat and fried food. That kind of diet, however, will increase the levels of 27HC and body weight.

UC San Francisco scientists identify second 'short sleep' gene after 10-year search

After a decade of searching, the UC San Francisco scientists who identified the only human gene known to promote "natural short sleep" -- lifelong, nightly sleep that lasts just four to six hours yet leaves individuals feeling fully rested -- have discovered a second.

High-protein bedtime snacks do not disturb overnight fat metabolism for active women

Physically active women who have foresworn bedtime snacks should feel no fear cracking open the cupboards after sundown for a protein-rich treat, according to new Florida State University-led research.

Researchers uncover how the brain remembers motor sequences

Ever wondered what was going on in the brain of John Coltrane when he played the famous solo on his album Giant Steps? Researchers at the National Institute of Information and Communications Technology, Japan, and Western University, Canada, have succeeded in visualizing how information is represented in a widespread area in the human cerebral cortex during a performance of skilled finger movement sequences.

Scientists identify PoEMs that promote breast cancer metastasis

When breast cancer cells spread through the body, they do so mainly through the lymph system that normally removes excess fluid and waste products from our tissues.

Social and executive brain functions critical for effective communication

Impairments in social and executive brain functions hinder effective communication, according to research in patients with dementia recently published in eNeuro.

Scientists discover potential novel target for treating deadly brain cancer

Scientists at USC and UC San Diego have discovered a potential novel target for treating glioblastoma, the deadly brain cancer that took the life of Sen. John McCain and kills 15,000 Americans a year.

Maternal high-fat diet may slow learning ability in offspring, study suggests

In a bid to further explore how a mother-to-be's diet might affect her offspring's brain health, Johns Hopkins Medicine researchers have found that pregnant and nursing rats fed high fat diets have offspring that grow up to be slower than expected learners and that have persistently abnormal levels of the components needed for healthy brain development and metabolism.

Empa researchers aim to gain a better understanding of bone failure

Can analytical methods from materials science help us better understand human bones? A research team at Empa in Thun is pursuing precisely this approach.

Researchers study biological risk potential of nanoparticles

Nanoparticles are smaller than five nanometres - a nanometre being one millionth of a millimetre - which corresponds approximately to the size of macromolecules. Such tiny particles are very easily absorbed in body cells.

Traumatic brain injuries could be healed using peptide hydrogels

Traumatic brain injury (TBI) –– defined as a bump, blow or jolt to the head that disrupts normal brain function –– sent 2.5 million people in the U.S. to the emergency room in 2014, according to statistics from the U.S. Centers for Disease Control and Prevention.
