Researchers identify potential new combination treatment for pancreatic cancer
Researchers identify potential new combination treatment for pancreatic cancer
FINDINGS Researchers from UCLA's Jonsson Comprehensive Cancer Center have identified a possible new therapeutic strategy using two types of drug inhibitors at once to treat one of the world's deadliest cancers. The combination approach uses one drug that inhibits the process — known as lysosome — that allows cancer cells to recycle essential nutrients to survive, and another drug that blocks the pathway used to repair DNA.

Butterfly numbers down by two thirds
Butterfly numbers down by two thirds
Meadows adjacent to high-intensity agricultural areas are home to less than half the number of butterfly species than areas in nature preserves. The number of individuals is even down to one-third of that number. These are results of a research team led by Jan Christian Habel at the Technical University of Munich (TUM) and Thomas Schmitt at the Senckenberg Nature Research Society.

Nicotine addiction from vaping is a bigger problem than teens realize
As the vaping epidemic continues, researchers point to well-known health risks associated with nicotine. Data show clearly that young people are vaping in record numbers. And despite the onslaught of reports and articles highlighting not only its dangers but the marketing tactics seemingly aimed to hook teens and young adults, the number of vaping users continues to climb.  These teens may be overlooking (or underestimating) a key ingredient in the vapors they inhale: nicotine.

Antiretroviral therapy crucial in preventing non-Hodgkin lymphoma
A research team led by the Yale School of Public Health has found that for people living with HIV/AIDS, both recent immunosuppression (a low recent CD4 T-cell count [white blood cells that fight infection]) and prolonged HIV viremia (the presence of HIV in the blood) play important and independent roles in the development of non-Hodgkin lymphoma.

Humans switch between apps in ’remarkably similar’ ways, scientists find
Humans are unknowingly adhering to a universal pattern when they flick between apps on their smartphones, scientists have discovered. Experts from Cardiff University have shown that although we spend a varying amount of time glued to our screens, the way in which we specifically switch between our different apps is remarkably similar.

Taking gravity from strength to strength
Ten years ago, ESA launched one of its most innovative satellites. GOCE spent four years measuring a fundamental force of nature: gravity. This extraordinary mission not only yielded new insights into our gravity field, but led to some amazing discoveries about our planet, from deep below the surface to high up in the atmosphere and beyond.

How our body «listens» to vibrations
How our body «listens» to vibrations
UNIGE researchers show that, for the brain, sounds and vibrations are ultimately quite similar. This would explain why vibrations are sometimes as unpleasant as noise pollution. We all know the feeling of a mobile phone vibrating in our hands when announcing an incoming call. If we perceive these vibrations so clearly, it is due to specialized receptors that transduce them into neural signals sent to our brain.

Precision work for large molecules
Precision work for large molecules
Quantum cascade lasers are able to measure the smallest molecules with high precision. But the technology has failed to measure larger gas molecules - until now! Empa researchers have succeeded in quantifying ethanol, an important organic molecule, with the aid of such a laser. In collaboration with the Swiss Federal Institute of Metrology (METAS), a team of researchers has successfully developed a method for determining the concentration of ethanol in a gas mixture with a very high proportion of water vapour and carbon dioxide.

Protein BRCA1 as a Stress Coach
Protein BRCA1 as a Stress Coach
03/20/2019 Two proteins work hand in hand to ensure that the tumour cells of neuroblastoma can grow at full speed. In "Nature", a Würzburg research team shows how the proteins can do this. Anyone who has ever studied the molecular basis of breast cancer will probably have heard of the abbreviation BRCA1 - this is a protein that protects the cells of breast tissue against cancer.

Starving bacteria can eject their tails to save energy and stay alive
When nutrients are dangerously low, a group of bacteria have been found to take the drastic measure of getting rid of their tails. Some bacteria use tails, or flagella, to swim through liquids - including those in our bodies. However, new research published today in PLOS Biology reveals a surprisingly drastic measure taken by some bacteria when facing starvation: they eject their flagella, leaving themselves paralyzed, but conserving energy so they can stay alive.

Managed retreat due to rising seas is a public health issue
Sea-level rise associated with climate change is a concern for many island and coastal communities. While the dangers may seem far off for large coastal cities like Miami or New Orleans, the advancing oceans are already displacing some small indigenous communities, and many others are at risk around the world.

Public-sector research boosts cleantech start-ups
Cleantech start-ups in the USA that cooperate with government research agencies outperform their competitors both in terms of patents and funding. That is the conclusion of a study by the Technical University of Munich (TUM), the University of Maryland and the University of Cambridge. In the cleantech sector, where development processes can extend over many years, public-private partnerships could prove valuable in other countries, too.
