Understanding brain tumors in children
07/04/2020 - The causes of 40% of all cases of certain medulloblastomas -- dangerous brain tumors affecting children -- are hereditary. A genetic defect that occurs in 15% of these children plays a key role by...
Blocking the iron transport could stop tuberculosis
07/04/2020 - The bacteria that cause tuberculosis need iron to survive. Researchers have now solved the first detailed structure of the transport protein responsible for the iron supply. When the iron transport...
Models explain changes in cooking meat
07/04/2020 - Mathematicians show that by modelling meat as a fluid-saturated matrix of elastic proteins, which are deformed as the fluid moves, cooking behaviors can be simulated more precisely.
Surprising hearing talents in cormorants
07/04/2020 - The great cormorant has more sensitive hearing under water than in air. This new knowledge may help protect vulnerable bird species.
What can be learned from the microbes on a turtle's shell?
07/04/2020 - Researchers have found that a unique type of algae, usually only seen on the shells of turtles, affects the surrounding microbial communities. It is hoped that these findings can be applied to...
Understanding how the protein tau moves between neurons yields insight into possible treatments for neurodegenerative diseases
07/04/2020 - In the fight against neurodegenerative diseases such as frontotemporal dementia, Alzheimer's and Chronic Traumatic Encephalopathy, the tau protein is a major culprit. Found abundantly in our...
Codexis, Takeda Sign Gene Therapy Collaboration
03/04/2020 - Partnership to leverage Codexis’ protein engineering platform to advance novel gene therapies for rare genetic disorders
Eat less, live longer
25/03/2020 - LA JOLLA—If you want to reduce levels of inflammation throughout your body, delay the onset of age-related diseases and live longer—eat less food. That’s the conclusion of a new study by...
Alzheimer's and an unusual molecular chaperone
25/03/2020 - A research team elucidates the aggregation mechanism of the Alzheimer protein tau.
Chip-based devices improve practicality of quantum-secured communication
25/03/2020 - Researchers have demonstrated new chip-based devices that contain all the optical components necessary for quantum key distribution while increasing real-world security. The fast and cost-effective...
Disease Knows No Borders: UC to Address COVID-19 Impacts on U.S-Mexico Region
25/03/2020 - As the spread of COVID-19 has permeated communities around the world, experts from the University of California are looking at how to protect those most vulnerable along the U.S.-Mexico border.
Engineers zap and unstick underwater smart glue
25/03/2020 - Turning adhesion on and off is what makes a glue smart. Inspired by nature, catechols are synthetic compounds that mimic the wet-but-still-sticky proteins found in mussel feet and offer promise for...
Events - The global refugee compact and its consequences for refugee protection - 3 March 2020, Brussels, Belgium
26/02/2020 - This conference gathers high-profile decision makers and stakeholders to discuss the possible consequences of the Global Refugee Compact for refugee protection. Economic and political crises...
New drug helps to preserve brain cells for a time after stroke
26/02/2020 - A team took a novel, interdisciplinary approach to analyzing the behavior of breast tumor cells by employing a statistical modeling technique more commonly used in physics and economics. The team was...
Cryptographic 'tag of everything' could protect the supply chain
26/02/2020 - To combat supply chain counterfeiting, which can cost companies billions of dollars annually, researchers have invented a cryptographic ID tag that's small enough to fit on virtually any product...
New green technology generates electricity 'out of thin air'
26/02/2020 - Electrical engineers and microbiologists have created a device they call an 'Air-gen' or air-powered generator, with electrically conductive protein nanowires produced by the microbe...
New encapsulation technique protects electronic properties of sensitive materials
26/02/2020 - Researchers are searching for tiny components that function reliably in increasingly narrow electronic configurations. Promising elements include the chemical compounds indium selenide and gallium...
Drug combo reverses arthritis in rats
31/01/2020 - LA JOLLA—People with osteoarthritis, or “wear and tear” arthritis, have limited treatment options: pain relievers or joint replacement surgery. Now, Salk researchers have discovered that a...
Women still face barriers to breastfeed at work
24/01/2020 - Despite the protections in place to support breastfeeding for employees, the burden still falls on working mothers to advocate for the resources they need, according to a new study.
Tiny devices made of DNA detect cancer with fewer false alarms
09/01/2020 - A new cancer-detecting tool uses tiny circuits made of DNA to identify cancer cells by the molecular signature on their surface. The circuits work by attaching to the outside of a cell and analyzing...
Finding the smallest genes could yield outsized benefits
09/01/2020 - LA JOLLA—While scientists know of about 25,000 genes that code for biologically important proteins, additional, smaller genes hiding in our DNA may be just as important. But these tiny lines of...
