Update: The story has been updated to include comments from Capella Space CEO Payam Banazadeh and Phase Four. Paragraph five and six have been updated with additional context on solar flair activity and premature satellite reentry, and paragraph eleven contains additional information on Phase Four technology.

Capella Space’s synthetic aperture radar satellites are falling back to Earth much sooner than the three years they were anticipated to operate, according to publicly available satellite data.

The startup has launched a total of ten small satellites to low Earth orbit since 2018, including eight in its family of “Whitney”-class spacecraft. Five of these satellites have reentered the atmosphere since the end of January of this year, including three of the Whitneys. Those Whitney sats were in orbit for less than two-and-a-half years; one, Capella-5, was in orbit for less than two years.

The gold that makes up your most precious jewelry may have been forged in a violent cosmic collision millions or billions of light years away between two neutron stars. New research seeks to better understand this process.

There is only a single confirmed site in the Universe capable of generating conditions extreme enough to initiate the production process for many of the heaviest elements in the Universe, including gold, platinum, uranium – neutron star.

A neutron star is the collapsed core of a large (between 10 and 29 solar masses) star. Neutron stars are the smallest and densest stars known to exist. Though neutron stars typically have a radius on the order of just 10 — 20 kilometers (6 — 12 miles), they can have masses of about 1.3 — 2.5 that of the Sun.

The recent Ant-Man movie did a great job of putting quantum up in lights, but the future of quantum science shines even brighter than fiction. One application, quantum sensors, is already the basis of some of the most important systems and technologies in our world — global positioning systems (GPS) and magnetic resonance imaging (MRI) scanners are prime examples.

Quantum sensors and quantum AI are just the beginning: Robots are now getting the quantum sensor treatment too. Quantum sensors will supercharge the way robots work and how we apply them to important 21st-century challenges.

Assessments of the health impacts of the non-sugar sweetener aspartame are released today by the International Agency for Research on Cancer (IARC) and the World Health Organization (WHO) and the Food and Agriculture Organization (FAO) Joint Expert Committee on Food Additives (JECFA). Citing “limited evidence” for carcinogenicity in humans, IARC classified aspartame as possibly carcinogenic to humans (IARC Group 2B) and JECFA reaffirmed the acceptable daily intake of 40 mg/kg body weight. Aspartame is an artificial (chemical) sweetener widely used in various food and beverage products since the 1980s, including diet drinks, chewing gum, gelatin, ice cream, dairy products such as yogurt, breakfast cereal, toothpaste and medications such as cough drops and chewable vitamins.

An expert panel found a potential association with liver cancer, but too little research exists to assume a causal connection. For now, the WHO left current consumption guidelines unchanged.

Lymphedema is the buildup of lymph in your body. Lymph is a fluid surrounding tissues. Lymph moves through vessels in the lymph system and into the bloodstream. The lymph system is a major part of the immune system.

(WTAJ) — The U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) is issuing a public health alert due to concerns about a raw beef product that may be contaminated.

According to the release, the raw beef item may contain soft, clear plastic. FSIS is issuing this public health alert to ensure that consumers are aware that this product should not be consumed. However, the product is no longer available for purchase.

A team of researchers from British universities has trained a deep learning model that can steal data from keyboard keystrokes recorded using a microphone with an accuracy of 95%.

When Zoom was used for training the sound classification algorithm, the prediction accuracy dropped to 93%, which is still dangerously high, and a record for that medium.

Such an attack severely affects the target’s data security, as it could leak people’s passwords, discussions, messages, or other sensitive information to malicious third parties.

India’s third moon mission’s spacecraft, Chandrayaan-3, is one step closer to a lunar landing after the Indian Space Research Organisation (ISRO), announced that it has successfully entered the moon’s orbit, on Saturday (August 5).

ISRO’s Chandrayaan-3 mission update.

The announcement was made by the Indian space agency on X, formerly known as Twitter where it wrote: “‘MOX, ISTRAC, this is Chandrayaan-3. I am feeling lunar gravity’. Chandrayaan-3 has been successfully inserted into the lunar orbit.”
