Nasa dismisses report that alien life announcement is imminent
Nasa has no announcements to make about the discovery of alien life, a spokesperson said, dismissing media reports which claimed that the US space agency was about to discover extraterrestrial life. Last week, the hacking group Anonymous posted a video on YouTube suggesting that Nasa is about to announce the discovery of life beyond Earth. Contrary to some reports, there's no pending announcement from Nasa regarding extraterrestrial life, Nasa science chief Thomas Zurbuchen said in a Twitter post.
The stable retrograde orbit of the Bee-Zed asteroid explained
Asteroid 2015 BZ509, also known as Bee-Zed, takes 12 years to make one complete orbit around the sun. This is the same orbital period as that of Jupiter, which shares its orbit but moves in the opposite direction. The asteroid with the retrograde co-orbit was identified by Helena Morais, a professor at Sao Paulo State University's Institute of Geosciences & Exact Sciences (IGCE-UNESP).
New wound healing properties of ficin researched
Ficin, an enzyme derived from figs latex, has been found to be active against biofilms formed by Staphylococcus. The project is headed by Senior Research Associate of the Microorganism Genetics Lab Ayrat Kayumov and funded by Russian Science Foundation and Project 5-100. He says, If you treat wounds with an enzyme or protease, healing accelerates. Together with our Voronezh University colleagues, we decided to try ficin, which has not yet been studied well.
Firms scramble to recover from wave of cyberattacks
Thousands of computer users across the globe scrambled on Wednesday to reboot after a wave of ransomware cyberattacks spread from Ukraine and Russia across Europe to the United States. The new attack appeared much smaller in scale, with global cybersecurity firm Kaspersky Lab estimating the number of victims at 2,000. Some IT specialists identified the newcomer as Petrwrap, a modified version of ransomware called Petya which circulated last year.
A bioplastic derived from soya protein which can absorb up to 40 times its own weight
Researchers at the University of Seville, together with experts from the University of Huelva, have obtained a natural bioplastic from soya protein that is capable of absorbing up to 40 times its own weight. The researchers are exploring its use in horticulture, specifically as a raw material from which to make agricultural nutrient dispensers. They are trying to reduce the use of artificial polymers and use another plastic that is natural and biodegradable.
Sunscreen creams break down into dangerous chemical compounds under the sunlight
The ability of avobenzone to absorb ultraviolet light in a wide range of wavelengths has ended in its widespread use in lipsticks, creams and other cosmetics. Although the substance is safe, the Russian scientists have proved that in water solution, it's capable of breaking down into hazardous chemical compounds. These experiments simulated the real situation in which a sunscreen is applied to the skin of swimmers. This reliable method allows conducting qualitative and quantitative analysis of the most complex mixtures of chemical compounds.
Space junk to be cleared using magnetic space tugs to prevent satellite collisions [VIDEO]
Accumulation of excess dead satellites in space is becoming a major concern for astronomers as it can make space travel pretty dangerous. The researchers are planning to use magnetic space tugs to tackle the dead satellites. When their mission ends, they continue to float in space and are capable of triggering danger by clashing with other satellites. This would result in increasing the space debris and make space travel a risky affair.
Philips buys US cardiac-implant firm for 1.9 bln euros
Dutch electronics giant Philips Wednesday announced it was buying for 1.9 billion euros ($2.2 billion) a specialist US company manufacturing ground-breaking treatments for heart and vascular diseases to broaden its health portfolio. The Amsterdam-based company said it would acquire Spectranetics, which has developed a range of lasers and balloons for treating blockages in cardio and arterial vessels.
Cambodia conservationists find rare cache of crocodile eggs
Wildlife researchers in Cambodia say they've found a clutch of eggs from one of the world's most endangered crocodiles, raising hopes of its continuing survival in the wild. The New York-based Wildlife Conservation Society said Wednesday that its researchers, along with Fisheries Administration employees and local residents, had found six eggs of the Siamese Crocodile in the southern province of Koh Kong as they were exploring for tracks, signs and dung of the reptile.
Wildlife species causing 'significant damage' to life, property across the country: Scientists
Upto 32 wildlife species are causing significant damage to life and property across India, say scientists who urge that the country must strengthen human-wildlife conflict management to reduce the losses. Rural families use up to 12 different mitigation techniques to protect their crops, livestock and property. Across wildlife reserves, people reported average crop losses amounting to Rs 12,559 and Rs 2,883 of livestock losses annually.
'On your mark, get set'-Neutrons run enzyme's reactivity for better biofuel production
Producing biofuels like ethanol from plant materials requires various enzymes to break down the cellulosic fibers. Scientists using neutron scattering have identified the specifics of an enzyme-catalyzed reaction that could significantly reduce the total amount of enzymes used, improving production processes and lowering costs. A deeper understanding of the enzyme reactivity could also lead to improved computational models that will further guide industrial applications for cleaner forms of energy.
Facebook to livestream Champions League football games
Facebook will broadcast Champions League matches for American internet users under a deal with Fox Sports, which will host the livestreams on its pages, the channel said Tuesday. The partnership will involve two group matches per day, four round of sixteen games and the four quarter-finals of the 2017-18 season, in the social media giant's latest foray into sportscasting. Facebook will act only as a host for the streams, with the images and content produced by Fox Sports.
Finding friends: Lonely elephant arrives at Los Angeles Zoo
The Los Angeles Zoo has a new elephant-a lonely pachyderm from Fresno. The zoo says a 46-year-old Asian female named Shaunzi arrived Tuesday after being trucked 215 miles from the Fresno Chaffee Zoo in a special crate. Shaunzi was born in Thailand and spent much of her youth in a circus before arriving in Fresno with another elephant named Kara. The two females were constant companions until Kara died earlier this month.
Are asteroids humanity's 'greatest challenge'?
The largest occur once every 100 million years, and the next impact could well ring in the end of human civilisation. Far, experts have managed to list more than 90 percent of asteroids in the dino-killing range, and determined that none poses an immediate threat. A much bigger concern is the whereabouts of millions of asteroids in the 15- to 140-metre (49- to 460-feet) range. At the very least, it would allow for cities to be evacuated, or a shockwave warning to be issued.
Toshiba pushes back closing deal on memory unit sale
Japanese electronics and energy giant Toshiba has delayed its deadline for reaching an agreement on selling its lucrative computer memory chip business. Tokyo-based Toshiba had hoped to have an agreement in time for Wednesday's shareholders meeting, being held in a city east of Tokyo. Financially ailing Toshiba is facing the risk of having its shares delisted and needs the cash from selling Toshiba Memory Corp.
'Ransomware' wave seemed aimed at old flaw and Ukraine
A global wave of cyberattacks exploited an already patched vulnerability in Windows software and appeared to have Ukraine as a primary target, according to computer security specialists. The first reports of trouble came from Ukrainian banks, Kiev's main airport and Rosneft, in a major incident reminiscent of the recent WannaCry virus. The bedeviling onslaught Tuesday was also being referred to as ransomware by US software titan Microsoft and security specialists.
In rural Kentucky, solar eclipse preparation keeps town busy
The first coast-to-coast total solar eclipse in the US in 99 years has heightened anticipation and excitement in small, rural towns of southwestern Kentucky. With 32,000 people, Hopkinsville is nearest the point of greatest eclipse. One shop owner says she'll camp at work instead of risking traffic, though the city requested National Guard help on roads. The mayor says Hopkinsville residents are ready and excited to host eclipse-chasers from around the world.
Scientists create better tools to study the processes of life
The University of Leeds in collaboration with Avacta Life Sciences, a Leeds spin-out company has developed tools, called Affimer technology, which can replicate the work of animal-derived antibodies traditionally used to help study biological molecules and processes. Like antibodies, Affimer technology can bind tightly to a target molecule to help scientists study its actions. For many years researchers have used animal-derived antibodies to indicate the presence of biological molecules and to study how they work.
Predicting eruptions using satellites and math
Volcanologists are beginning to use satellite measurements and mathematical methods to forecast eruptions and to better understand how volcanoes work, shows a new article in Frontiers in Earth Science. Climate researchers have also used the same method to estimate the long-term evolution of the climate due to carbon emissions. Volcanologists are just beginning to explore whether the technique can also be used to forecast volcanic eruptions. Such reservoirs are typically miles below the surface and, as such, they're nearly impossible to study with existing methods.
This Is When Volcanoes Appeared In Human Stories For The Very First Time
Written texts of volcanoes do go back incredibly far into the past, however. Most major religions reference volcanic eruptions or volcanoes quite clearly. Well Pandora herself was crafted and designed by none other than Vulcan (Roman)/Hephaestus (Greek), the deity of fire, volcanoes and forging weapons. Dating back even further, a Mesoamerican temple in the shape of a volcano can be found hiding within coastal Peru.
