Physicists reach atomic-scale telegraphy with light
In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking work, the unit of frequency.....»»
Catalyst search shows how computing can take the guesswork out of chemistry
Imagine synthesizing and then testing over 50 different complex molecules to identify the most effective catalyst for a particular chemical reaction. The traditional approach to developing new catalysts for chemical reactions in this "try it and see".....»»

Pirate Site Blocking Agency Reveals How and Why Pirates Circumvent Blocking
As the Motion Picture Association's site-blocking drive lands back on home turf, countries that have already implemented their own site-blocking programs are evaluating their effectiveness. A new survey carried out by French anti-piracy agency Arcom.....»»
Subscene’s Demise is No Surprise But Millions of App Users Face Disruption
After reporting that the site hasn't been financially viable for years, the operator of Subscene, one of the internet's most important subtitle sites, has pulled the plug. The plan had been known for some time and at least two, mostly complete backup.....»»
Pirate Site Owners Must Surrender, Informants Get Five-Figure Reward
After re-writing the rules of anti-piracy enforcement, the P.CoK team at Kakao Entertainment have now torn up the rulebook, set it on fire, and thrown both its remains and conventional thinking out of a window. For a limited time only, pirate site ow.....»»
Z-Library Confusion as ‘Official’ Social Media Announces Crackdown in China
Last month Z-Library reported that users in China were experiencing difficulties accessing the site, with new domains being blocked very quickly. The site's official WeChat and Bilibili social media accounts seemed unaffected until a surprise announc.....»»
A photocatalyst for sustainable syngas production from greenhouse gases

Researchers discover three ingots made of Roman lead in Northern Córdoba
Three ingots from the site of Los Escoriales de Doña Rama (Belmez) and dating from the Roman era demonstrate the importance of lead production and exportation in northern Córdoba. Measuring some 45 centimeters long and weighing between 24 and 32 ki.....»»
Regulating branch development of petunias
Branching is a pivotal determinant of plant architecture, not only influencing the capacity of the plant to adapt to its environment but also significantly impacting crop yield, ornamental characteristics, and production economics of horticultural pl.....»»
Geologists reveal mysterious and diverse volcanism in lunar Apollo Basin, Chang"e-6 landing site
The far side of the moon is a mysterious place that is never visible from the Earth. The most remarkable feature of the moon is its asymmetry between the lunar near side and far side in composition, crust thickness, and mare volcanism. Scientists hav.....»»

Geologists, biologists unearth the atomic fingerprints of cancer
Scientists at the University of Colorado Boulder and Princeton University have, for the first time, employed a tool often used in geology to detect the atomic fingerprints of cancer......»»
Scientists directly measure a key reaction in neutron star binaries
An X-ray burst (XRB) is a violent explosion that occurs on the surface of a neutron star as it absorbs material from a companion star. During this absorption, increasing temperatures and densities on the surface of the neutron star ignite a cascade o.....»»
BlackBasta claims Synlab attack, leaks some stolen documents
The BlackBasta ransomware / cyber extortion gang is behind the recent cyber attack that resulted in the temporary shutdown of operations at Synlab Italia. The group claimed the attack on their leak site on Saturday and says they have exfiltrated appr.....»»
