There are good papers everywhere e.g. Nature Photonics IF = 32.9 is based on 238 papers. Optics Letters (OL) IF = 3.3 is based on 3240 papers. Recomputing the IF of OL based on its top 238 papers gives IF ~ 12. A mistake to focus only on the left column I think.

Fun fact. In November 2026, NASA's Voyager 1 will become the first human-made object to reach a distance of one light-day from Earth (about 25.9 billion kilometers). This milestone will be reached after more than 47 years of travel since its launch in 1977.

Deep in a New Zealand swamp, scientists discovered an ancient kauri tree that had been entombed for more than 40,000 yearsโ€”its trunk preserved like a wooden time capsule. But this wasnโ€™t just any prehistoric tree. Its rings revealed something extraordinary: it had lived through

This map should be included in every history book... History is not there for you to like or dislike. It is there for you to learn from it. And if it offends you, even better. Because then you are less likely to repeat it. Itโ€™s not yours for you to erase or destroy. โค๏ธ

โ€œIn Finland, the number of homeless people has fallen sharply. Those affected receive a small apartment & counselling with no preconditions. 4 out of 5 people affected make their way back into a stable life. And all this is cheaper than accepting homelessness.โ€

We are deeply saddened to hear of the passing of Papa Jake Larson, a true American hero and beloved D-Day veteran. At 102 years old, Jake was one of the last living links to the bravery, sacrifice, and determination of the Greatest Generation. Jake landed on Omaha Beach on June

Iโ€™m glad to see some sensible advice on this. I started full time in Horizon just after turning 37, and I was able to build the company primarily because I had gone through college and grad school and spent years doing research to become expert in an emerging technology.

Ever wonder why the Sun looks yellow from Earth when itโ€™s actually white? Our atmosphere scatters blue light, leaving mostly yellow and red wavelengths to reach our eyes. Learn more about the Sun: asc-csa.gc.ca/eng/astronomy/โ€ฆ ๐Ÿ“ท: NASA/JPL-Caltech/MSSS/Texas A&M Univ.
