But the latest work has divided developmental biologists. Some question the need for such experiments using closely related primates — these animals are not likely to be used as model animals in the way that mice and rodents are. Nonhuman primates are protected by stricter research ethics rules than are rodents, and they worry such work is likely to stoke public opposition.
The chimaeras lived up to 19 days — but some scientists question the need for such research.
Local health authorities in several parts of the United States are monitoring dozens of travelers for Ebola after the Centers for Disease Control (CDC) ordered airlines to collect information on people who’d been in several western African countries, including Guinea or the Democratic Republic of Congo.
Washington state is monitoring at least 23 travelers. Another 45 are being watched in Ohio. Four people are also being monitored in Oregon.
Ebola is highly contagious and causes severe illness that often leads to death. Symptoms include fever, headache, pain and unexplained bleeding or bruising.
Spot was apparently being used for reconnaissance.
Pictures of the exercises were shared on Twitter by France’s foremost military school, the École Spéciale Militaire de Saint-Cyr. It described the tests as “raising students’ awareness of the challenges of tomorrow,” which include the “robotization of the battlefield.”
A report by French newspaper Ouest-France offers more detail, saying that Spot was one of a number of robots being tested by students from France’s École Militaire Interarmes (Combined Arms School), with the intention of assessing the usefulness of robots on future battlefields.
Boston Dynamics’ vice president of business development Michael Perry told The Verge that the robot had been supplied by a European distributor, Shark Robotics, and that the US firm had not been notified about this particular use. “We’re learning about it as you are,” says Perry. “We’re not clear on the exact scope of this engagement.” The company says it was aware that its robots were being used with the French government, including the military.
Halloween is forever if you’re a Japanese black bear.
The Japanese city of Takikawa is using robot wolves to prevent bear attacks. Bear encounters have been on the rise as cities have grown and acorns — a key part of black bears’ pre-hibernation diet — have become harder to find. Since these robots were installed in Takikawa, there have been no attacks in the city’s surrounding area.
The tendency of many cellular proteins to form protein-rich biomolecular condensates underlies the formation of subcellular compartments and has been linked to various physiological functions. Understanding the molecular basis of this fundamental process and predicting protein phase behavior have therefore become important objectives. To develop a global understanding of how protein sequence determines its phase behavior, we constructed bespoke datasets of proteins of varying phase separation propensity and identified explicit biophysical and sequence-specific features common to phase-separating proteins. Moreover, by combining this insight with neural network-based sequence embeddings, we trained machine-learning classifiers that identified phase-separating sequences with high accuracy, including from independent external test data.
Intracellular phase separation of proteins into biomolecular condensates is increasingly recognized as a process with a key role in cellular compartmentalization and regulation. Different hypotheses about the parameters that determine the tendency of proteins to form condensates have been proposed, with some of them probed experimentally through the use of constructs generated by sequence alterations. To broaden the scope of these observations, we established an in silico strategy for understanding on a global level the associations between protein sequence and phase behavior and further constructed machine-learning models for predicting protein liquid–liquid phase separation (LLPS). Our analysis highlighted that LLPS-prone proteins are more disordered, less hydrophobic, and of lower Shannon entropy than sequences in the Protein Data Bank or the Swiss-Prot database and that they show a fine balance in their relative content of polar and hydrophobic residues.
Measurements of the muon magnetic moment strengthen a previously reported tension with theoretical predictions, ushering in a new era of precision tests of the standard model.
Employees play a vital role in ensuring their company’s cybersecurity bubble remains intact. Many malware campaigns begin by sending an e-mail communication to employees. To learn basic cybersecurity hygiene, employees must become familiar with password management, identify and report security threats, and recognize suspicious behavior. Regular content and training will assist employees in countering any malware threats they encounter.
Adopt a culture of comprehensive security.
Given the ongoing evolution of malware attacks and their capability to surpass what they were capable of, organizations should prioritize a strong malware protection strategy. Consultation with experienced cybersecurity experts like Indusface can help them create a solution that meets their needs.
Multiple one-click vulnerabilities have been discovered across a variety of popular software applications, allowing an attacker to potentially execute arbitrary code on target systems.
The issues were discovered by Positive Security researchers Fabian Bräunlein and Lukas Euler and affect apps like Telegram, Nextcloud, VLC, LibreOffice, OpenOffice, Bitcoin/Dogecoin Wallets, Wireshark, and Mumble.
“Desktop applications which pass user supplied URLs to be opened by the operating system are frequently vulnerable to code execution with user interaction,” the researchers said. “Code execution can be achieved either when a URL pointing to a malicious executable (.desktop,.jar,.exe, …) hosted on an internet accessible file share (nfs, webdav, smb, …) is opened, or an additional vulnerability in the opened application’s URI handler is exploited.”
New Horizons is the fifth most distant spacecraft from Earth.
Pioneer 10, which was launched in 1972 and was the first probe to pass through the asteroid belt and to fly by Jupiter, reached 50 AU on Sept. 22, 1990. Today, it is approximately 129 AU from Earth.
Its sister ship, Pioneer 11, reached 50 AU a year later in 1991. It was launched in 1973 and in addition to flying by Jupiter, was the first to make direct observations of Saturn. It is now about 105 AU from Earth.
