Scientists hunt 'anti-evolution' drugs in new cancer fight

By Ben Hirschler LONDON (Reuters) - Scientists are opening a new front in the war on cancer with plans to develop "anti-evolution" drugs to stop tumour cells from developing resistance to treatment. Britain's Institute of Cancer Research (ICR), one of the world's top cancer centres, said on Friday its initiative was the first to have at its heart the target of overcoming cancer evolution and drug resistance. In the same way that bacteria evolve resistance to antibiotics, cancer cells also change to evade the medicines used to fight them, leading to "survival of the nastiest".

Brazil scientists find Zika traces in Culex mosquitoes in wild

Brazilian researchers on Thursday said they found signs of the Zika virus in a common mosquito that is a separate species from the insect known to be the primary means of transmission. The scientists, from a leading Brazilian research institute known as the Oswaldo Cruz Foundation, discovered the Zika traces in Culex mosquitoes captured in and around the northeastern Brazilian city of Recife, capital of the state that was hit hardest by the Zika outbreak since last year. In March, the same researchers said they had successfully transmitted the Zika virus to Culex mosquitoes in the lab, but were not yet sure at the time whether the species could carry the virus naturally.

Newly developed wheel converts any bicycle into an electric vehicle

Right off the bat, Michael Burtov said he and his team at technology startup GeoOrbital did not re-invent the wheel. After two years and five prototypes, the Cambridge, Massachusetts-based startup has developed a new type of electric bicycle wheel that steered the company into crowdfunding stardom raising more than $1.2 million at a record-setting pace on Kickstarter.   The newly developed bicycle wheel has the major components of an electric vehicle – a 500 watt motor, a lithium battery and a suit of electronics, all arranged to fit perfectly into the radial of a wheel made out of high density foam to avoid a flat. “The unique thing about this wheel is that we rearranged it," Michael Burtov, the CEO & Founder of GeoOrbital said.

Chickens May Help Repel Malaria-Carrying Mosquitoes

In a perhaps unexpected finding, the smell of live chickens could help in the fight against malaria, new research shows. Researchers looked at the behavior of the malaria-carrying mosquito Anopheles arabiensis in three villages in western Ethiopia, where people commonly share their living quarters with their livestock. BecauseAnopheles mosquitoes primarily use their sense of smell to find hosts, the scientists collected hair, wool and feathers from the cattle, sheep, goats and chickens in the villages, identified scent compounds known as odorants that were unique to each and then investigated how well these odorants repelled the mosquitoes.

Was Zika Contracted in Florida? How the Virus Could Spread Locally

Health officials in Florida are investigating a case of Zika that may have been acquired locally rather than in another country. For someone to acquire Zika in Florida, a person infected with Zika would have to spread the virus to a mosquito, which then would spread it to another human. For example, a new chain of "locally acquired" cases of Zika could happen if a Florida resident were to travel to a country where Zika is spreading, become infected with the virus and then return to Florida, where they would be bitten by a mosquito while the Zika virus was in their blood.

Why Comparing Yourself to Others Is Normal

That's because people automatically compare their own performance with that of others, according to the study, published today (July 20) in the journal Neuron. When they're cooperating with another person, they perceive that person's performance as a reflection on their own: A better partner makes people feel better about their own abilities, while a worse partner makes them feel incompetent, too.

Robot with Sea Slug Parts Makes Hybrid Debut

Researchers have developed a hybrid robot built with body parts from a novel source: sea slugs. The new robot combines a Y-shaped muscle from the mouth of a California sea hare (Aplysia californica) with a 3D-printed skeleton. The robot was modeled after the way sea turtles crawl, because the researchers wanted to create something that could move with only one Y-shaped muscle, study lead author Victoria Webster, a graduate student at Case Western Reserve University in Cleveland, told Live Science in an email.

Create 3D Animations with the Stroke of a Pen

With just the stroke of a pen or the click of a mouse, you can now transform your 2D sketches into 3D animations. New computer software, known as Mosketch, allows anyone to try their hand at 3D animation without toiling away at numerous sketches. Now available in beta, Mosketch was developed by Moka Studio and École Polytechnique Fédérale de Lausanne (EPFL), a research institute in Switzerland that specializes in physical sciences and engineering.

Scientists looking for invisible dark matter can't find any

WASHINGTON (AP) — Scientists have come up empty-handed in their latest effort to find elusive dark matter, the plentiful stuff that helps galaxies like ours form.

'Witch' Prison Revealed in 15th-Century Scottish Chapel

An iron ring set in the stone pillar of a 15th-century chapel in the Scottish city of Aberdeen may not look like much, but historians say it could be a direct link to a dark chapter in the city’s past — the trial and execution of 23 women and one man accused of witchcraft during Aberdeen's "Great Witch Hunt" in 1597. "I was skeptical, to be honest — the ring is not all that spectacular, but it is actually quite genuine," said Arthur Winfield, project leader for the OpenSpace Trust in the United Kingdom, which is restoring the chapel as part of a community-based redevelopment of the East Kirk sanctuary at the historic Kirk of St Nicholas, in central Aberdeen. Winfield told Live Science that two places within the kirk (the Lowland Scots word for "church") had been equipped as a prison for witches snared in the Aberdeen witch hunt: the stone-vaulted chapel of St Mary, and the tall steeple of the kirk, which was at that time the tallest structure in the c…

Caribbean Cave Art Illuminates Encounters with Europeans

Puerto Rico's Mona Island is famous for its vast network of caves. In these dark underground chambers, archaeologists have discovered engravings by indigenous people and early European colonizers alike. Led by Jago Cooper, of the British Museum in London, and Alice Samson, of the University of Leicester, a group of researchers spent years documenting the subterranean artwork at Mona Island —which is about halfway between the main island of Puerto Rico and Hispaniola.

Hottest Year Ever? 2016 Burns Through Heat Records, NASA Says

This year may be only half over, but 2016 is already on track to be the hottest year ever on record, with each of the first six months, from January to June, setting new temperature records, NASA officials announced this week. For the first time, NASA shared a midyear climate analysis, doing so because temperature averages this year have been so in excess of previous data, agency officials said. NASA's data showed that each month in 2016 was the warmest respective month globally in the modern temperature record, which dates to 1880.
