Medical Xpress / FDA authorizes first standalone robotic device to draw blood
The U.S. Food and Drug Administration has authorized Aletta as the first standalone robotic device that can draw blood from a patient's arm. Marketing authorization was granted to Vitestro.
Phys.org / Three photons at once beat the standard photon test
Physicists at the University of Twente have improved the standard test for the quality of individual particles of light. By letting three photons interfere at the same time instead of two, they draw more information from ...
Phys.org / Scientists 'see' nanoscale forces, providing evidence of electric fields at the air‑water interface
Bubbles are round, and we know surface tension does that. But squeeze that gas-liquid boundary into a space only a few tens of nanometers wide—could other forces be at work?
Phys.org / Largest catalog yet of how human cells read DNA shows how chemical marks alter genetic instructions
Every cell in the body contains essentially the same DNA, yet a brain cell behaves differently from a muscle cell or an immune cell. The difference lies largely in how each cell reads its genetic instructions.
Phys.org / Area affected by wildfires in Europe could almost triple due to climate change
Increasingly hot, dry and windy conditions could substantially extend the area affected by wildfires across Europe, according to a new study led by the Potsdam Institute for Climate Impact Research (PIK) with contributions ...
Medical Xpress / A molecule released during exercise may help protect muscles weakened by type 2 diabetes
Scientists have discovered that a key molecule released during exercise strengthens muscles, improves exercise performance and could be a potential therapeutic treatment for muscle damage caused by type 2 diabetes.
Phys.org / How ancient trees are warning us about the next enormous solar storm
Our sun is capable of storms far bigger than we've ever recorded. Studying the world's oldest trees suggests we could soon be due one of these gargantuan events.
Phys.org / Who's watching who? Otters turn their attention to humans
For many people, a trip to the zoo is a chance to watch playful otters dart through the water and chatter with one another. But while we may worry that crowds could stress the otter community, a new Australian study shows ...
Phys.org / DNA's physical properties may shape which mutations evolution preserves
Nearly every cell in the human body contains essentially the same genetic information, yet different cells activate different genes. For regulatory proteins to reach these genes, DNA must be accessible. This accessibility ...
Medical Xpress / Researchers find cold storage platelets safe and effective
A new study has found platelets kept in cold storage are as effective at treating bleeding and have a longer shelf life than platelets stored at room temperature. Dr. James Preuss and Dr. Warren Pavey, from The University ...
Phys.org / Dying radio galaxies suggest a shorter, more dynamic afterlife for black hole jets
Astronomers have uncovered a previously underexplored population of faint, rapidly fading remnant radio galaxies, offering new insights into what happens after supermassive black holes stop powering their enormous radio jets.
Medical Xpress / Newly found 'immune organ' inside skull directs brain defense
Researchers at Washington University School of Medicine in St. Louis have discovered lymph node-like structures in the skull bone marrow of mice for the first time and demonstrated that they act as rapid first responders ...
