Wasps are already scary enough, but scientists from the University of California Riverside created a new breed of mutant wasps featuring terrifying red eyes.
According to a report from UC Riverside, the team introduced the new strain of wasps to prove that the CRISPR gene-slicing technology can be applied to the parisitic jewel wasps. With the success of this project, the scientists have a new method of studying the biology of the wasp including how males are able to turn all their progeny into males.
The way the males are able to produce only male offspring is an intriguing mystery that scientists are looking forward to cracking. Assistant professor of entomology Omar Akbari explained, “To understand that, we need to pursue their PSR (paternal sex ratio) chromosomes, perhaps by mutati… Read more

Elephants are naturally intelligent social creatures, but Mali is being held in deplorable and isolated conditions in Philippines’ Manila Zoo.

Imagine being trapped in a tiny room all your life, completely isolated and never being able to run free, play with other children or even socialize with fellow humans. Such is the life of Mali, a lonely elephant who has been trapped in an enclosure in Manila Zoo in the Philippines since 1997.
According to Free Mali, she was captured in Sri Lanka when she was just a nursing baby. That was 40 years ago. Since then, the majestic creature has spent her days in a cramped cage within a zoo that«s only a total of 0.055 square kilometers. Mali hasn»t even seen another elephant in over 30 years.
There are a few balls, a tire, running water and some paintings of trees in Mali«s enclosure, a report from The Dodo said. But that»s i… Read more

Blood from human umbilical cords just may be the key in fighting back aging. Researchers from the Stanford University School of Medicine found that the protein located in the blood can actually boost learning and memory in older mice, opening the potential of new treatments for age-related mental declines, according to a report from Medical Xpress.
«Neuroscientists have ignored it and are still ignoring it, but to me it’s remarkable that something in your blood can influence the way you think,» senior author Tony Wyss-Coray, PhD, explained. Wyss-Coray participated in a previous study that showed older mice displaying improved memory and learning after the infusion of young… Read more
Are jellies our oldest known living ancestor?

Where did humans come from? The answer might be jellies.
In a new paper published in the journal Nature Ecology and Evolution, scientists from the Vanderbilt University and University of Wisconsin-Madison suggested that ctenophores or comb jellies were the first animals on Earth.
For years, the scientific community has been debating whether jellies or sponges came first. Both creatures emerged around 500 million years ago, but one has to come first, right?
According to a report from Gizmodo, this recent study used a new genetic technique to conclude that the oldest of all animal species are the comb jellies, although the interpretative nature of the data might mean that the debate might be far from over.
To prove that the comb jelly has the most ancient genome in the world, the researchers a… Read more
PCB concentration of 9mg/kg is already considered damaging to marine mammals, meaning the PCBs found in Lulu’s blubber extremely goes beyond the limit.

Last year, a killer whale named Lulu, who was thought to have died after being entangled in fishing nets, washed ashore the Isle of Tiree in Scotland.
As mentioned by The Guardian, after a series of post-mortem examinations, results have revealed that Lulu’s blubber contains shocking levels of a toxic chemical known as polychlorinated biphenyls (PCB) 950mg/kg, to be exact. In addition, it was found out that she never had a calf despite having lived for at least 20 years.
In 2016, a separate study found out that PCBs harm breeding success and immune systems of not just killer whales but many marine mammals, including dolphins. It also revealed that Europe’s cetaceans have levels of PCBs that… Read more
Artificial intelligence could soon pave the way to cross-species communication, starting with dolphins.

In a few years, humans can do more than just play with dolphins — it«s possible we can also talk to them. Swedish start-up technology company Gavagai and Sweden»s Royal Institute of Technology (KTH) are teaming up to develop an artificial intelligence technology that would make it possible to translate the sounds dolphins make, according to a report from The Local.
«The technology models meaning instead of structure,» Gavagai CEO Lars Hamberg explained. «It is unsupervised, and it continuously learns meaning by itself, by observing every language’s usage — much like a human. The technology is based on many years of world-leading research.»
The research will include four years of working with bottlenose dolphin… Read more
For the first time ever, researchers record the normally herbivorous deer eating a human carcass.

For the first time ever, a deer was spotted snacking on human flesh.
According to a report from Popular Science, scientists from the Forensic Anthropology Research Facility (FARF) were studying the reactions of scavengers on human remains when they left a body in the woods. The team monitored the site with a motion-sensitive camera, which was able to catch a range of scavengers such as vultures, raccoons and coyotes, among others.
Nearly one year after they began the experiment — the body has been scavenged into a mere skeleton at this point — the researchers spotted a young white-tailed deer by the carcass with a human rib bone in its mouth. A few days later, there was another glimpse of a deer with ano… Read more
Male great tits ( Parus major ) choose neighbors with similar personalities to their own, according to new research from the University of Oxford, UK.
Johnson et al assessed whether a great tit breeding population is structured by personality. Image credit: Shirley Clarke / Fordingbridge Camera Club / CC BY-SA 3.0.
Lead author Katerina Johnson, a doctoral student in the University of Oxford’s Departments of Zoology and Experimental Psychology, and co-authors investigated whether the personality of birds influences their social lives — in particular who they choose to nest near.
The study involved analyzing social network structure in a population of wild great tits at Wytham Woods, Oxfordshire, UK, over six consecutive breeding seasons.
“We found that males, but not females, were picky about p… Read more
Two new tarsier species have been discovered in the forests of the northern peninsula of Sulawesi, Indonesia.

Tarsiers are small, nocturnal, predaceous primates of the 45-million-year-old family Tarsiidae.
They are intermediate in form between lemurs and monkeys, measuring up to 6 inches (15 cm) long and weighing 100 – 150 g.
They have elongated hind legs and feet, a thin tail and long fingers. Their fur is velvety or silky and buff, grayish brown, or dark brown on the back and grayish or buffy on the underside.
These primates have the largest eyes relative to body size of any mammal on Earth, each typically larger than the… Read more

Marine biologists are baffled by the huge numbers of dead leopard sharks being washed ashore San Francisco Bay, from San Mateo to Bolinas.
Since the second week of March, hundreds of dead leopard sharks have been spotted at the shorelines of Oakland, Berkeley, Hayward, Foster City, Redwood City, Alameda and San Francisco. The huge die-off of the stripped fish is considered to be largest leopard shark mortality event since 2011.
«My estimate is that several hundred sharks have already died,» said Mark Okihiro, the senior fish pathologist for the California Department of Fish and Wildlife, as per SF Gate. “There appears to be no leveling off of shark deaths in the bay. I am still getting reports from locati… Read more
