Lightning no longer a mystery, physicist publishes landmark paper revealing clues about phenomenon

Posted by in category: climatology

It is essential to understand how lightning works so that buildings, airplanes, skyscrapers, and people can be protected more effectively.

Ever wondered why lightning zig-zags? Or how it is connected to the thundercloud ago? You might have tried looking up the many textbooks on the lightning but failed to find a definite and convincing answer.

A key enzyme in brain function shuts off randomly, study reveals

Posted by in categories: biotech/medical, chemistry, neuroscience

The finding could have implications on drug development beyond neuroscience.

A new study conducted by researchers at the University of Copenhagen has found that V-ATPase, an enzyme thought to be a key component of brain function, switches off randomly, even for hours at a time. This discovery has the potential to change our understanding of how our brain functions, according to a press release.

V-ATPase is an enzyme that can break down ATP molecules, the cell’s energy currency, as they pump protons across cellular membranes.

Life on Mars? Scientists confirm that Mars’ Jezero Crater was full of organic materials

Posted by in category: alien life

The search continues for signs of ancient alien life on the red planet.

NASA’s Perseverance mission on Mars has performed several world firsts, including the first controlled flight on another planet and the first extraction of oxygen from the Martian atmosphere.

New Mars findings point to ancient alien life.

Marvelous engineering of Voyager: The aircraft that traveled around the world without refueling

Posted by in categories: engineering, transportation

The flying fuel tank’s flight “was arguably aviation’s last milestone.”

Nearly 36 years ago, on December 23, 1986, pilots Dick Rutan and Jeana Yeager, designer Burt Rutan, and crew chief Bruce Evans earned the Collier Trophy, aviation’s most prestigious award, according to a NASA report published in 2013.

FDA just approved the world’s most expensive drug that costs $3.5 million

Posted by in categories: biotech/medical, neuroscience

It could actually be cheaper than other treatment options.

The U.S. Food and Drug Administration (FDA) recently approved a new drug Hemgenix, to be used in patients with hemophilia B, a blood clotting disorder. Since the condition is rare, it will be used only in a small group of patients worldwide.

Hope for first blood test to detect deadly heart inflammation

Posted by in category: biotech/medical

The first blood test to diagnose inflammation of the heart muscle (myocarditis) could be in use in as little as a year, following the discovery of a molecular signal in the blood by Queen Mary University of London researchers. The research, published today in the journal Circulation, offers hope of a quick and cheap way of diagnosing the condition.

Myocarditis is a difficult condition to diagnose. Symptoms include a temperature, fatigue, chest pain and shortness of breath, which can all be easily mistaken for other conditions. The gold standard method for diagnosis is a biopsy, an expensive, invasive, and risky procedure which can sometimes still miss signs of the condition. It’s estimated that one young person dies suddenly every week in the UK due to previously undiagnosed myocarditis.

Now, a team of researchers led by BHF Professor Federica Marelli-Berg at Queen Mary University of London have found that the presence of T-cells—a type of white cell—expressing a molecule called cMet in the blood strongly indicates that a person has myocarditis. They say that cMet-expressing T cells levels could be detected through a routine blood test that could cost less than £50 with results available within hours.

Microscale structure of rock affects microseismicity at underground carbon dioxide storage site

Posted by in categories: climatology, computing, sustainability

Mitigating and reversing the effects of climate change is the most important scientific challenge facing humanity. Carbon sequestration describes a range of technologies with the potential to reduce the concentration of carbon dioxide (CO2) in the atmosphere. Most of these schemes involve storing the gas underground, however, this is not without risk, and scientists are concerned that underground storage could lead to increased seismic activity (a phenomenon known as “induced seismicity”).

Now, researchers in the US and Switzerland have studied microseismicity, the small seismic events caused by carbon injection into host rock, at the Illinois Basin Decatur Project (IBDP) in the midwestern US. In 2011–2014, the IBDP injected one million tonnes of CO2 into an underground reservoir just above a rhyolite crystalline basin. Nikita Bondarenko and Roman Makhnenko at the University of Illinois and Yury Podladchikov at the University of Lausanne have used a combination of field observations and computer simulations to show how microseismicity at the IBDP is highly dependent on the microscale structure of the host rock.

WHO, CDC: A record 40 million kids miss measles vaccine dose

Posted by in categories: biotech/medical, surveillance

LONDON (AP) — The World Health Organization and the U.S. Centers for Disease Control and Prevention say measles immunization has dropped significantly since the coronavirus pandemic began, resulting in a record high of nearly 40 million children missing a vaccine dose last year.

In a report issued Wednesday, the WHO and the CDC said millions of children were now susceptible to measles, among the world’s most contagious diseases. In 2021, officials said there were about 9 million measles infections and 128,000 deaths worldwide.

The WHO and CDC said continued drops in vaccination, weak disease surveillance and delayed response plans due to COVID-19, in addition to ongoing outbreaks in more than 20 countries, mean that “measles is an imminent threat in every region of the world.”

Scientists demonstrate world’s first continuous-wave lasing of deep-ultraviolet laser diode at room temperature

Posted by in categories: biotech/medical, computing

A research group led by 2014 Nobel laureate Hiroshi Amano at Nagoya University’s Institute of Materials and Systems for Sustainability (IMaSS) in central Japan, in collaboration with Asahi Kasei Corporation, has successfully conducted the world’s first room-temperature continuous-wave lasing of a deep-ultraviolet laser diode (wavelengths down to UV-C region).

These results, published in Applied Physics Letters, represent a step toward the widespread use of a technology with the potential for a wide range of applications, including and medicine.
