It seems like yesterday — not 10 years ago — that Steve Jobs took the stage at MacWorld to debut Apple’s latest new gadget: the iPhone.
The iPhone was three devices in one, he declared at Moscone West in San Francisco. It was a widescreen iPod with touch controls, a revolutionary mobile phone, and a breakthrough Internet communications device.
Apple’s “three-in-one device” has gone on to become a critical contributor to the company’s success, accounting for more than half its revenues annually, as well as a can’t-live-without tool for many people.
New, Complex Call Recorded in Mariana Trench Believed to Be From Baleen whale
A sound in the Mariana Trench notable for its complexity and wide frequency range likely represents the discovery of a new baleen whale call, according to the Oregon State University researchers who recorded and analyzed it.
Scientists at OSU’s Hatfield Marine Science Center named it the “Western Pacific Biotwang.”
Lasting between 2.5 and 3.5 seconds, the five-part call includes deep moans at frequencies as low as 38 hertz and a metallic finale that pushes as high as 8,000 hertz.
Summary: Researchers have proposed in-orbit reference datasets for calibrating weather satellites. A recent presentation demonstrated that using these references reduced errors in microwave and infrared weather satellites to fractions of a degree Celsius.
“Traffic and weather, together on the hour!” blasts your local radio station, while your smartphone knows the weather halfway across the world. A network of satellites whizzing around Earth collecting mountains of data makes such constant and wide-ranging access to accurate weather forecasts possible. Just one satellite, such as the National Oceanic and Atmospheric Administration’s (NOAA) Geostationary Operational Environmental Satellite-R that launched in 2016, can collect 3.5 terabytes of weather data per day.
Hummingbirds See Motion in an Unexpected Way
Summary: Have you ever imagined what the world must look like to hummingbirds as they zoom about at speeds of up to 60 miles per hour? According to new evidence on the way the hummingbird brain processes visual signals you can’t. That’s because a key area of the hummingbird’s brain processes motion in a unique and unexpected way.

Review looks at studies on chicken intelligence, social development and emotions
Suummary: Chickens are not as clueless or ‘bird-brained’ as people believe them to be. They have distinct personalities and can outmaneuver one another. They know their place in the pecking order, and can reason by deduction, which is an ability that humans develop by the age of seven. Chicken intelligence is therefore unnecessarily underestimated and overshadowed by other avian groups.
Chickens are not as clueless or “bird-brained” as people believe them to be. They have distinct personalities and can outmaneuver one another. They know their place in the pecking order, and can reason by deduction, which is an ability that humans develop by the age of seven. Chicken intelligence is therefore unnecessarily underestimated and overshadowed by other avian groups. So says Lori Marino, senior scientist for The Someone Project, a joint venture of Farm Sanctuary and the Kimmela Center in the USA, who reviewed the latest research about the psychology, behavior and emotions of the world’s most abundant domestic animal. Her review is published in Springer’s journal Animal Cognition.
Why you should NEVER feed your baby water – and how it could be fatal if you do
There are plenty of warnings and advice about giving your baby water. Here’s what you need to know
Whether you’re expecting or in those early, blurry first days of parenthood, you will have most likely come across a wealth of baby-related information.
Feeding babies, weaning babies, sleep-training your baby, all those milestones, all the things to avoid, all the individual expert opinions.

The universe is expanding faster than anyone had previously measured or calculated from theory. This is a discovery that could test part of Albert Einstein’s theory of relativity, a pillar of cosmology that has withstood challenges for a century.
Nasa and the European Space Agency jointly announced the universe is expanding 5% to 9% faster than predicted, a finding they reached after using the Hubble space telescope to measure the distance to stars in 19 galaxies beyond theMilky Way.
Zika Virus Case in Utah Raises New Questions for Scientists
Scientists from the Centers for Disease Control and Prevention (CDC) are scrambling to figure out how a Utah caregiver became ill with Zika.
The virus is overwhelmingly transmitted via bites from infected mosquitoes, but can also spread through sexual contact. The case in Utah seems to be the result of something completely different, however, say state officials. Scientists aren’t exactly sure how the person became infected, but they working to figure what’s behind this latest twist in the ongoing epidemic.
In a dingy apartment building, insulated by layers of hanging rugs, the last family on Earth huddles around a fire, melting a pot of oxygen. Ripped from the sun’s warmth by a rogue dark star, the planet has been exiled to the cold outer reaches of the solar system. The lone clan of survivors must venture out into the endless night to harvest frozen atmospheric gases that have piled up like snow.
As end-of-humanity scenarios go, that bleak vision from Fritz Leiber’s 1951 short story “A Pail of Air” is a fairly remote possibility. Scholars who ponder such things think a self-induced catastrophe such as nuclear war or a bioengineered pandemic is most likely to do us in. However, a number of other extreme natural hazards—including threats from space and geologic upheavals here on Earth—could still derail life as we know it, unraveling advanced civilization, wiping out billions of people, or potentially even exterminating our species.
Yet there’s been surprisingly little research on the subject, says Anders Sandberg, a catastrophe researcher at the University of Oxford’s Future of Humanity Institute in the United Kingdom. Last he checked, “there are more papers about dung beetle reproduction than human extinction,” he says. “We might have our priorities slightly wrong.”
Frequent, moderately severe disasters such as earthquakes attract far more funding than low-probability apocalyptic ones. Prejudice may also be at work; for instance, scientists who pioneered studies of asteroid and comet impacts complained about confronting a pervasive “giggle factor.” Consciously or unconsciously, Sandberg says, many researchers consider catastrophic risks the province of fiction or fantasy—not serious science.
Researchers found efforts such as joining Scouts or exposure to classical music led to little or no impact on attainment
Texting parents about their children’s homework proved to be cheaper and more effective in improving exam results than a series of other efforts, including joining the Scouts, exposure to classical music or individual tuition over the internet, according to new research.
Trials funded by the Educational Endowment Foundation found no substance in a number of myths, with most of the studies showing little or no impact in terms of attainment even if several resulted in improved self-confidence and teamwork.
