A new smart monitoring system could help doctors avoid mistakes—but it’s also alarming some surgeons and leading to sabotage.

“Kepler contributed many historical benchmarks in astronomy and physics in the 17th century, leaving his legacy even in the space age,” said Hisashi Hayakawa.

How can 400-year-old sunspot drawings help modern-day scientists with solar cycles? This is what a recent study published in The Astrophysical Journal Letters hopes to address as an international team of researchers used 400-year-old drawings of sunspots to better understand solar cycles and how we can study them in the future. This study holds the potential to help researchers use non-electronic scientific tools to gain greater insight into scientific discoveries around the world.

For the study, the researchers examined drawings of sunspots made by Johannes Kepler in 1,607 along with past notes to ascertain which solar cycle these sunspots belonged to, which could help astronomers piece together solar cycles during that time and predict them, as well.

Researchers’ detection of two gases, phosphine and ammonia, in the clouds of Venus raises speculation about possible life forms in the planet’s atmosphere.

It’s critical for leaders to know when to make a difficult decision before it leads to an unavoidable setback.

The dense peaks in the wavelength distribution graph observed in a Lyman-Alpha forest indeed resemble many small trees. Each of those peaks represents a sudden drop in “light” at a specific and narrow wavelength, effectively mapping the matter that light has encountered on its journey to us.

Aging is a universal experience, evident through changes like wrinkles and graying hair. However, aging goes beyond the surface; it begins within our cells. Over time, our cells gradually lose their ability to perform essential functions, leading to a decline that affects every part of our bodies, from our cognitive abilities to our immune health.

To understand how cellular changes lead to age-related disorders, Calico scientists are using advanced RNA sequencing to map molecular changes in individual cells over time in the roundworm, C. elegans. Much like mapping networks of roads and landscapes, we’re charting the complexities of our biology. These atlases uncover cell characteristics, functions, and interactions, providing deeper insights into how our bodies age.

In the early 1990s, Cynthia Kenyon, Vice President of Aging Research at Calico, and her former team at UCSF discovered genes in C. elegans that control lifespan; these genes, which influence IGF1 signaling, function similarly to extend lifespan in many other organisms, including mammals. The genetic similarities between this tiny worm and more complex animals make it a useful model for studying the aging process. In work published in Cell Reports last year, our researchers created a detailed map of gene activity in every cell of the body of C. elegans throughout its development, providing a comprehensive blueprint of its cellular diversity and functions. They found that aging is an organized process, not merely random deterioration. Each cell type follows its own aging path, with many activating cell-specific protective gene expression pathways, and with some cell types aging faster than others. Even within the same cell type, the rate of aging can vary.

The captivating world of quantum mechanics is constantly evolving, revealing complexities that challenge our perception of reality. Recent advancements illuminate the puzzling wave functions of entangled photons, providing remarkable insights into the behavior of these fundamental particles.

At the forefront of this research are experts from the University of Ottawa and Sapienza University of Rome. Their innovative approach allows for real-time visualization of entangled photon wave functions, pushing the boundaries of what we thought possible in quantum science.

Quantum entanglement is a mind-boggling phenomenon that underscores the profound interconnectedness of two particles.

WASHINGTON — The U.S. Space Force awarded Akima’s subsidiary Five Rivers Analytics a $480 million 10-year contract to support and modernize the Satellite Control Network — a decades-old system of 19 globally distributed parabolic antennas spread across several locations worldwide.

Akima, an Alaska Native Corporation-owned defense contractor, won the contract dubbed STORMS (Satellite Control Network Tracking Station Operations, Remote Site and Mission Partner Support).

The STORMS contract is an Indefinite Delivery/Indefinite Quantity (IDIQ) agreement. This type of contract allows the Space Force to procure services as needed over a specified period. It succeeds the previous $445 million CAMMO (Consolidated Air Force Satellite Control Network Modifications and Maintenance Operations) contract won by CACI International in 2016.
