Ministerstvo obchodu Spojených států připravuje nová digitální pravidla. Americké podniky by na základě nich mohly spolupracovat s čínskou firmou Huawei Technologies na stanovování norem pro mobilní sítě (5G). Agentuře Reuters to řekly zdroje obeznámené se situací. Loni touto dobou přitom USA uvalily restrikce na obchodování s Huawei.

Současná koronavirová krize otřásla finančními trhy, zlevněné akcie jsou příležitostí, jak zhodnotit investici. Jenomže kdy je správná chvíle investovat? Už se trhy odrazily ode dna, nebo přijde další propad? A jak snížit riziko špatného načasování? Nad tím se zamýšlí Michal Valentík, investiční analytik společnosti Broker Trust.

Práci z domova u zaměstnanců soukromých firem nelze jednostranně nařídit, vzniká jen na základě dohody obou stran. U pedagogických pracovníků a zaměstnanců škol však platí trochu jiná pravidla. Ve spolupráci s právníky Bořivojem Líbalem a Markem Polonim přinášíme odpovědi na nejčastější dotazy pedagogů.

Like in Newtonian kinematics, the relativistic change of reference frame must be a vector system of transformation laws for position, velocity and acceleration. In special relativity, when changing the reference frame the coordinates of a moving point is transformed using Lorentz transformation. But the velocity-addition formula that transforms velocity is in a too different mathematical...

(University of Southampton) Scientists have published highly detailed images of lab-grown neurons using Extreme Ultraviolet radiation that could aid the analysis of neurodegenerative diseases.

(Florida Atlantic University) Despite PPE use, reports show that many health care workers contracted COVID-19. A novel training technique reinforces the importance of using proper procedures to put on and take off PPE when caring for patients during the pandemic. Researchers vividly demonstrate how aerosol-generating procedures can lead to exposure of the contagion with improper PPE use. The most common error made by the health care workers was contaminating the face or forearms during PPE removal.

(Goethe University Frankfurt) According to modern particle physics, matter produced when neutron stars merge is so dense that it could exist in a state of dissolved elementary particles. This state of matter, called quark-gluon plasma, might produce a specific signature in gravitational waves. Physicists at Goethe University Frankfurt and the Frankfurt Institute for Advanced Studies have now calculated this process using supercomputers.

(SCALE Nanotech) ESA-backed researchers demonstrate the laser-propulsion of graphene sails in microgravity. The light sails use a scalable micro-membrane design that minimizes their mass and hence increases their thrust upon light irradiation. To demonstrate the new sail concept, the scientists gained access to ZARM Drop Tower. There, the sail prototypes were set in vacuum and microgravity, and 1W-lasers caused their acceleration up to 1 m/s2.

SAVANNAH—Gregory and Travis McMichael have been arrested and charged with murder and aggravated assault in connection with the February killing of Ahmaud Arbery, the Georgia Bureau of Investigation announced Thursday. According to police, the white father and son, 64 and 34, chased Arbery, a 25-year-old black man, after he ran by Travis McMichael’s home in the Satilla Shores neighborhood of Brunswick on Feb. 23. He was unarmed and jogging at the time. “This is a start towards victory,” Thea Brooks, Arbery’s aunt, told The Daily Beast on Thursday. “This only the beginning though, but this is what we were all hoping for.”The McMichaels said they believed Arbery was a burglar responsible for a series of break-ins in their neighborhood and that they pursued him in their pickup truck while armed with a shotgun and a .357 magnum. The GBI alleges the McMichaels confronted Arbery, and that Travis shot him. A local prosecutor previously indicated a third man, William Bryan, took part in the chase and filmed the incident.‘It’s Murder’: This Shooting of an Unarmed Black Man Is Roiling GeorgiaAt least two shots hit the 25-year-old, the Glynn County Coroner’s Office told The Daily Beast last week.Video that Brooks said depicted her nephew’s death elicited a furious reaction nationwide, and residents of the area protested the initial failure to prosecute a case on Tuesday.“It’s murder. It’s heartbreaking to even look at. The whole city has seen it,” Brooks told The Daily Beast after the video was released this week.The Georgia NAACP echoed her words in a Thursday response to the McMichaels’ arrest: “The murderers of Ahmaud Arbery have been arrested.”Gregory McMichael, a former cop and investigator with a local prosecutor’s office, previously told The Daily Beast he “never would have gone after someone for their color.” He also said the “closest version of the truth” about the incident was captured in a letter effectively clearing him and his son that was written by a prosecutor who recused himself from the case, George Barnhill. McMichael also admitted he had no direct evidence that Arbery was a thief. “But he’s the guy who’s there without permission,” he said from behind the closed front door of his son’s home.The owner of an unfinished home just down the street from Travis McMichael's home, Larry English, told The Daily Beast earlier this week that he had surveillance footage that appeared to show Arbery stopping to look at the foundation of his still-under-construction home. While Gregory McMichael claimed to police that Arbery had been caught on surveillance video, it was not immediately clear what video he was referring to. English told The Daily Beast he had no knowledge of the McMichaels seeing his surveillance footage. McMichael’s ties to law enforcement helped fuel a haze of suspicion around the killing from the beginning. Barnhill was one of two area prosecutors who looked into the incident before recusing themselves. A third prosecutor—District Attorney Tom Durden—sought a GBI probe ahead of the arrests this week.Read more at The Daily Beast.Got a tip?

Top-down proteomics studies intact proteoform mixtures and offers important advantages over more common bottom-up proteomics technologies, as it avoids the protein inference problem. However, achieving complete molecular characterization of investigated proteoforms using existing technologies remains a fundamental challenge for top-down proteomics. Here, we benchmark the performance of ultraviolet photodissociation (UVPD) using 213 nm photons generated by a solid-state laser applied to the study of intact proteoforms from three organisms. Notably, the described UVPD setup applies multiple laser pulses to induce ion dissociation, and this feature can be used to optimize the fragmentation outcome based on the molecular weight of the analyzed biomolecule. When applied to complex proteoform mixtures in high-throughput top-down proteomics, 213 nm UVPD demonstrated a high degree of complementarity with the most employed fragmentation method in proteomics studies, higher-energy collisional dissociation (HCD). UVPD at 213 nm offered higher average proteoform sequence coverage and degree of proteoform characterization (including localization of post-translational modifications) than HCD. However, previous studies have shown limitations in applying database search strategies developed for HCD fragmentation to UVPD spectra which contains up to nine fragment ion types. We therefore performed an analysis of the different UVPD product ion type frequencies. From these data, we developed an ad hoc fragment matching strategy and determined the influence of each possible ion type on search outcomes. By paring down the number of ion types considered in high-throughput UVPD searches from all types down to the four most abundant, we were ultimately able to achieve deeper proteome characterization with UVPD. Lastly, our detailed product ion analysis also revealed UVPD cleavage propensities and determined the presence of a product ion produced specifically by 213 nm photons. All together, these observations could be used to better elucidate UVPD dissociation mechanisms and improve the utility of the technique for proteomic applications.
