mars volcano died at same time as dinosaurs


around the same time that the dinosaurs became extinct on earth, a volcano on mars went dormant, nasa researchers have learned. arsia mons is the southernmost volcano in a group of three massive martian volcanoes known collectively as tharsis montes. until now, the volcano's history has remained a mystery. but thanks to a new computer model, scientists were finally able to figure out when arsia mons stopped spewing out lava. according to the model, volcanic activity at arsia mons came to a halt about 50 million years ago. around that same time, earth experienced the cretaceous-paleogene extinction event, which wiped out three-quarters of its animal and plant species, including the dinosaurs.

volcanoes rocked mars for at least 2 billion years


volcanoes erupted on mars for nearly half of the planet's history, a new study suggests. a team of scientists determined that a mars meteorite known as northwest africa (nwa) 7635 cooled and solidified 2.4 billion years ago — about 2 billion years earlier than other, similar red planet rocks from the same "volcanic center." the finding indicates that mars hosts some of the longest-lived volcanoes in the solar system, study team members said. [7 biggest mars mysteries] the researchers, led by university of houston geology professor tom lapen, analyzed 0.07 ounces (2 grams) of material from the interior of nwa 7635, which was discovered in algeria in 2012. the scientists identified nwa 7635 as a type of volcanic rock called a shergottite, and they dated its solidification to 2.4 billion yea






olympus working on 8k video for micro four thirds: digital photography review


in an interview with french publication focus numerique senior representatives from olympus have revealed a number of interesting insights about what consumers can expect from the japanese manufacturer in the future, for example micro four third image sensor that support 8k video. general manager of olympus product planning, mr. akira watanabe, said: “we can assure you that there is no problem in developing sensors at 33 million pixels for filming in 8k. we started the 4/3″ saga with a sensor at 5 mpx in 2003. now the same sensor is at 20 mpx with a much higher image quality especially for the management of electronic noise.”in the same interview mr. watanabe suggests that olympus might be working on its own version of a bluetooth-based app, the likes of which samsung pioneered and has rec

lonely ice volcano on ceres may have once had company


the mystery of the dwarf planet ceres' lonely ice volcano may have just been solved. nasa's dawn probe discovered the 2.5-mile-high (4 kilometers) cryovolcano, named ahuna mons, in 2015. there's nothing else remotely like it on the 590-mile-wide (950 km) ceres — a fact that has had scientists scratching their heads. "imagine if there was just one volcano on all of earth," michael sori, of the lunar and planetary laboratory at the university of arizona, said in a statement. "that would be puzzling." [the dwarf planet ceres in p os] ahuna mons could simply be a one-of-a-kind feature. but new research by sori and his colleagues suggests another possible answer: ahuna mons may have once had company, older cryovolcanoes that flattened out and disappeared over the eons via a process called "vis

olympus plans autofocus, stabilization improvements for flagship e-m1 mark ii


why it matters to you early adopters of olympus’ new flagship era can rest ured that it is only going to get better from here on out.when it comes to image stabilization and autofocus performance, olympus’ om-d e-m1 mark ii is no slouch. the $2,000 flagship mirrorless era is a technological tour de force, and counts 4k video and an impressive 60 fps continuous shooting mode among its key features.that was enough to earn a digital trends editor’s choice award, but apparently olympus engineers think they can do even better, revealing that improvements to both stabilization and autofocus, among other things, could be coming via future firmware updates.“our [image stabilization] is becoming very, very sensitive. but we are not isfied with the current performance and will continue to improve i






olympus' redesigned scope is linked to infection outbreak


doctors have tied a superbug outbreak at a foreign health facility to a medical scope that olympus modified last year in an attempt to reduce its risk of spreading bacteria between patients.five patients treated with the modified device tested positive for the same potentially deadly bacteria, according to a report filed with the food and drug administration.one of those patients died, but the report blamed the death on the person's pre-existing condition rather than the infection.american hospitals are currently using about 4,400 of the devices that olympus voluntarily recalled last year to replace a small mechanism linked to deadly outbreaks around the world.several of those outbreaks happened in southern california hospitals, including at ucla ronald reagan medical center two years ago

predecessor to the mirrorless camera officially defunct -- so what's next for mi


why it matters to you the end of production of lenses for a camera system that hasn't launched a new body in over six years isn't surprising, but the landmark format continues to drive new ideas.the predecessor of olympus’ current mirrorless system has officially gotten the axe — lenses for the olympus zukio four thirds mount are now out of production. but, as the four thirds format fades into photographic history, the company is looking to take its little sibling, the micro four thirds, which started the mirrorless category, further with 8k video and the possibility of even more stabilization.the discontinuation comes at no surprise, since the last four thirds body from the company is over six years old. the idea stemmed from developing a camera with an optimal sensor size for both image

this dwarf planet's freaky ice volcano might not be alone after all


image: nasathe only thing cooler than a volcano is an ice volcano, obviously. scientists think they’ve spotted these mounds of icy rock—called cryovolcanoes—on many moons, such as triton, europa, titan, and demoted planet pluto (sorry, pluto). perhaps the strangest one of all is ahuna mons, a solitary ice giant half the size of mount everest, located on the dwarf planet ceres. but a new study suggests ahuna mons might not have always been the loneliest (ice) volcano in the solar system.advertisementa team of researchers at the university of arizona in tucson have taken a particular interest in ahuna mons, frankly because it’s a bit of an anomaly. “imagine if there was only one volcano on all of earth, and it was just one thing that had that shape and was made of lava” the study’s lead auth






dwarf planet ceres & the case of the vanishing ice volcanoes


the solitary mountain on the dwarf planet ceres may be slowly disappearing, following in the footsteps of earlier peaks.  new research suggests that the outer layer of the icy world may be slowly shifting over time, allowing the peak to gradually stretch out and sink into the crust. similar mountains may have peppered the planet in the past and flattened out over time. "it's sort of like if you spill some syrup or honey on a plate and you watch it spread out over time, not instantaneously like water does but a little more slowly, it eventually gets to a flatter, broader shape; it's the same process," michael sori, a planetary scientist at the university of arizona, told space.com. [nasa probe snaps stunning new pics of dwarf planet ceres] sori is lead author on a paper proposing that the m






throwback thursday: our first cameras: digital photography review


for this week's throwback thursday, i asked fellow dpreview staffers to write a few paragraphs about their first cameras, film and digital. i'll go first.jeff kellerunlike most of my colleagues, i wasn't a huge film photographer. i recall owning one of those flat 110 cameras, followed by a standard-issue clamshell compact, which was promptly stolen by someone in the baggage department at london's heathrow airport. i ended up running to harrods to pick up something similar. i probably paid way too much.i was lucky enough to get my hands on digital cameras really early – like 1996 early. after toying around with early kodak, casio and apple cameras, i finally bit the bullet and dropped $900 on the olympus d-300l, also known as the camedia c-800l. this powerhouse had an f2.8, 36mm-equivalent






u.s. senator seeks data on infection outbreak linked to 'repaired' olympus scope


saying she was alarmed by a new superbug outbreak, a u.s. senator on tuesday asked olympus for data showing its redesigned medical scope was safe.in a letter, sen. patty murray (d-wash.) asked the japanese device manufacturer for more information about a recent outbreak that sickened five patients in europe.the patients’ infections, all caused by the same drug-resistant bacteria, were linked to a scope that olympus recalled last year to replace a small mechanism. three independent investigations found that the mechanical part could spread deadly bacteria between patients.“this tragic incident is particularly alarming because your company recalled and reportedly fixed the device in question,” wrote murray. she asked the company for data proving that the “repaired” scope could be disinfected
