- By combining a novel metal, CeIrIn5, with a sapphire crystal, scientists can draw superconducting circuits into the crystal.
- Until now, the superconducting states were virtually impossible to manipulate in superconductors.
- CeIrIn5 has a unique property where some of it can be superconductive, while other parts of it retain a normal metallic state.
- Scientists that discovered this have also created a model that enables the design of complex conducting patterns by varying the temperature of the material.
- This could lead to new technologies, including a quantum version of a conventional transistor.
- Oxygen ventilation could be a more effective for carbon monoxide (CO) poisoning when coupled with phototherapy.
- When CO poisoning is associated with lung injury, a typical oxygen treatment is ineffective and sometimes dangerous.
- For a new treatment, scientists combined light that can detach CO from hemoglobin, with a membrane that enables oxygenation of blood and removal of CO.
- So far it’s only been tested in rats, where it increased the rate of CO removal by 3 times, and increased the survival rate of treated rats.
- First patient, in a study that will involve up to 45 people aged 18 - 35, has been successfully injected with over 2 billion CRISPR-edited cells.
- The patient suffers from sickle cell -- genetic disease causing defective hemoglobin that deforms red blood cells, impairing their ability to carry oxygen.
- Sickle cell has dramatic, long-term effects, and this treatment could help sickle cell patients lead a normal life.
- Scientists extract bone marrow cells from the patient, edit a gene that will make them produce fetal hemoglobin, and inject them again.
- Since it’s an experimental treatment, it will take several months to detect first signs of it, and years to understand whether it actually helped the patients.
- Resource Generation, a group of wealthy young people across America, are using their capital to transfer power to financially struggling communities.
- They want to decrease the earnings gap, and help more people have access to the opportunities that few -- except the wealthy -- can afford.
- The group is focused on smart redistribution of wealth, and wants to encourage people to openly talk about money and status.
- It has been around since the 1990s, and in the first half of 2019 members pledged $20 million to social justice and grassroots organizations.
- 38% of coral colonies, lost to a heat wave in 2003 around Spain’s Columbretes Islands, show signs of regrowth.
- This finding is promising in terms of saving coral reefs around the world.
- Coral is made of thousands of tiny creatures called polyps which, in the damaged coral, shrunk and gradually -- over several years -- grew into new formations.
- It’s the first time that this phenomenon was observed and it gives hope.
- However, the regrowth is still too slow, ~3 millimeters per year, considering that heat waves are happening more often.
