Toward unhackable communication: Single particles of light could bring the ‘quantum internet’

Posted by in categories: government, internet, particle physics, quantum physics

Hacker attacks on everything from social media accounts to government files could be largely prevented by the advent of quantum communication, which would use particles of light called “photons” to secure information rather than a crackable code.


Using light to send information is a game of probability: Transmitting one bit of information can take multiple attempts. The more photons a light source can generate per second, the faster the rate of successful information transmission.

“A source might generate a lot of photons per second, but only a few of them may actually be used to transmit information, which strongly limits the speed of quantum communication,” Bogdanov said.

‘Chemo brain’ caused by malfunction in three types of brain cells, study finds

Posted by in categories: biotech/medical, neuroscience

In a new #Stanford study explaining the cellular mechanisms behind cognitive impairment from chemotherapy, scientists have demonstrated that a widely used chemotherapy drug, #methotrexate, causes a complex set of problems in three major cell types within the brain’s white matter. The study also identifies a potential remedy.

Why the Future of Solar Power Is from Space

Posted by in categories: solar power, space, sustainability

Over seven decades ago in 1941, Isaac Asimov wrote a short story, “Reason” (PDF), in which energy captured from the sun was transmitted via microwave beams to nearby planets from a space station. Flash forward to today, scientists are looking to make that very science fiction dream a reality for Earth.

There has been tremendous research on space-based solar power (SBSP) or space solar power (SSP) since the mid 20th century. Here is a great timeline of the various international studies and projects related to SBSP.

Engineers create an inhalable form of messenger RNA

Posted by in category: biotech/medical

Messenger RNA, which can induce cells to produce therapeutic proteins, holds great promise for treating a variety of diseases. The biggest obstacle to this approach so far has been finding safe and efficient ways to deliver mRNA molecules to the target cells.


Patients with lung disease could find relief by breathing in messenger RNA molecules.

Binghamton University researchers design a more durable MEMS switch

Posted by in category: mobile phones

Researchers from Binghamton University’s Mechanical Engineering Department have developed a way to make cell phones and power lines more durable.


Assistant Professor Sherry Towfighian and graduate student Mark Pallay created a new type of microelectromechanical system – more commonly known as a MEMS switch – that uses electrostatic levitation to provide a more robust system.

“All cell phones use MEMS switches for wireless communication, but traditionally there are just two electrodes,” said Towfighian. “Those switches open and close numerous times during just one hour, but their current lifespan is limited by the two-electrode system.”

Novel fiber-optic device lays foundation for quantum-enhanced measurements

Posted by in categories: particle physics, quantum physics

Researchers at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) has developed and tested a new #Interferometer


January 3, 2019 — By analyzing a pattern formed by the intersection of two beams of light, researchers can capture elusive details regarding the behavior of mysterious phenomena such as gravitational waves. Creating and precisely measuring these interference patterns would not be possible without instruments called interferometers.

For over three decades, scientists have attempted to improve the sensitivity of interferometers to better detect how the number of photons—particles that make up visible light and other forms of electromagnetic energy—leads to changes in light phases. Attempts to achieve this goal are often hampered by optical loss and noise, both of which can decrease the accuracy of interferometer measurements.

India scientists dismiss Einstein theories

Posted by in categories: biotech/medical, government

Scientists in India have hit out at speakers at a major conference for making irrational claims, including that ancient Hindus invented stem cell research.

Some academics at the annual Indian Science Congress dismissed the findings of Isaac Newton and Albert Einstein.

Hindu mythology and religion-based theories have increasingly become part of the Indian Science Congress agenda.

Human Pilot Study Results for Senolytics Published

Posted by in categories: biotech/medical, life extension

The results from a human pilot study that focused on treating idiopathic pulmonary fibrosis with senescent cell-clearing drugs has been published. The drugs target aged and damaged cells, which are thought to be a reason we age and get sick, and remove them from the body.

Senescent cells and aging

As we age, increasing numbers of our cells become dysfunctional, entering into a state known as senescence. Senescent cells no longer divide or support the tissues and organs of which they are part; instead, they secrete a range of harmful inflammatory chemical signals, which are collectively known as the senescence-associated secretory phenotype (SASP).
