Log every request to corporate apps, no code changes required

When a user connects to a corporate network through an enterprise VPN client, this is what the VPN appliance logs: The administrator of that private network knows the user opened the door at 12:15:05, but, in most cases, has no visibility into what they did next. Once inside that private network, users can reach internal tools, sensitive data, and production environments. Preventing this requires complicated network segmentation, and often server-side application changes. Logging the steps that an individual takes inside…

The road less traveled — ScienceDaily

Two pathways diverged in a chemical synthesis, and one molecule took them both. Chemists at the University of Tokyo have studied how molecular building blocks can either form a spherical cage or an ultrathin sheet that shows some of the basic properties of a “smart” material that can respond to its environment. “This molecule is interesting because it builds different structures depending on the conditions when it reaches the bifurcation point of its synthesis,” said Professor Shuichi Hiraoka from the…

Transplanting new inhibitory neurons may repair damaged brain circuits — ScienceDaily

Researchers from the University of California, Irvine developed a breakthrough cell therapy to improve memory and prevent seizures in mice following traumatic brain injury. The study, titled “Transplanted interneurons improve memory precision after traumatic brain injury,” was published today in Nature Communications. Traumatic brain injuries affect 2 million Americans each year and cause cell death and inflammation in the brain. People who experience a head injury often suffer from lifelong memory loss and can develop epilepsy. In the study, the…

How nematodes outsmart the defenses of pests — ScienceDaily

The western corn rootworm causes economic losses of over 2 billion US dollars in maize cultivation and is thus a serious agricultural pest. Originally from America, the western corn rootworm is currently invading Europe, including Switzerland. A successful pest In an earlier study, Christelle Robert and Matthias Erb from the Institute of plant sciences (IPS) at the University of Bern elucidated one of the strategies that underlies the success of the western corn rootworm. Maize plants store certain defense substances,…

Researchers develop thin heat shield for superfast aircraft — ScienceDaily

The world of aerospace increasingly relies on carbon fiber reinforced polymer composites to build the structures of satellites, rockets and jet aircraft. But the life of those materials is limited by how they handle heat. A team of FAMU-FSU College of Engineering researchers from Florida State University’s High-Performance Materials Institute is developing a design for a heat shield that better protects those extremely fast machines. Their work will be published in the November edition of Carbon. “Right now, our flight…

Smart people may learn music faster — ScienceDaily

Intelligence could play a role, according to a Michigan State University study that investigated the early stages of learning to play piano. Published in the journal Intelligence, the study may be the first to examine the relationship between intelligence, music aptitude and growth mindset in beginner pianists. Growth mindset refers to whether students believe they can improve basic abilities, like piano ability. “The strongest predictor of skill acquisition was intelligence, followed by music aptitude,” said Alexander Burgoyne, a doctoral candidate…

A day in the life of a Backend Foundation Engineer at Slack

While it’s not always easy to get up before seven, particularly when the sun hasn’t risen yet, being able to get a head start on the day before most of the city begins their commute makes it worthwhile. I sneak out of bed and get ready for work. I’m typically out the door, down the four flights of stairs, and walking to the BART by 6:50. I’ll pop in my earbuds and boot up the latest podcast in my queue:…

Monitoring server applications with Vortex

At Dropbox, we use monitoring and alerting to gain insight into what our server applications are doing, how they’re performing, and to notify engineers when systems aren’t behaving as expected. Our monitoring systems operate across 1,000 machines, with 60,000 alerts evaluated continuously. In 2018, we reinvented our monitoring and alerting processes, obviating the need for manual recovery and repair. We boosted query speed by up to 10000x in some cases by caching more than 200,000 queries. This work has improved…

Collaborating to advance internet infrastructure

Today, we joined colleagues from across the industry — including service providers, system integrators, startups, technology providers, and other ecosystem partners — for the fourth annual Telecom Infra Project (TIP) Summit in Amsterdam. At the summit, TIP demonstrated momentum on a range of initiatives including new network deployments and trials of TIP solutions such as Disaggregated Cellsite Gateway and OpenRAN. A substantial expansion of the TIP Community Lab program was announced, as well as new resources available to the community,…

The more you bend it, the softer it gets — ScienceDaily

New research by engineers at the University of Illinois combines atomic-scale experimentation with computer modeling to determine how much energy it takes to bend multilayer graphene — a question that has eluded scientists since graphene was first isolated. The findings are reported in the journal Nature Materials. Graphene — a single layer of carbon atoms arranged in a lattice — is the strongest material in the world and so thin that it is flexible, the researchers said. It is considered…
